C, N, P and Si in dissolved, particulate, organic and inorganic forms, determined from 12 surveys in the river Oitabén-Verdugo during 2002, allowed quantification of the chemical composition, phase partitioning and fluxes of continental materials to the inner Ría de Vigo (NW Spain). Despite the large fluxes normalised to the drainage basin of the river Oitabén-Verdugo (280 mmol C m−2 y−1, 56.5 mmol N m−2 y−1, 1.35 mmol P m−2 y−1, and 61.3 mmol Si m−2 y−1), its reduced dimensions (350 km2) yielded relatively low concentrations of these species. Organic C, N and P represented 62%, 43% and 48% of the total C, N and P fluxes, respectively. About 90% of the organic C and N and 60% of the organic P was in the dissolved form. The chemical composition of the organic materials was compatible with detrital organic matter derived from aquatic plants, phytoplankton and soil leaching but not with unprocessed terrestrial plants. Significant temporal changes were observed in the chemical composition, related to the seasonal cycle of the biological activity in stream waters and soils, as well as the chemical weathering reactions. Spatial differences were due to the contrasting dynamic regime and, likely, the origin of the materials Financial support came from the Spanish ‘Ministerio de Educacio´ n y Ciencia’ (MEC) grant n REN2000-0880-C02-01 MAR and the ‘Xunta de Galicia’ (XUGA) grant n PGIDT01MAR40201PN.

This paper shows that this dam has an impact on Atlantic salmon (Salmo salar) migration and that adult fish experience adaptive responses. Upstream migration activities were recorded with a 70 kHz echosounder (SIMRAD EY500 model) during two monitoring programs in 2010 and 2011, combining a total of 172 days of data collection. The echosounder was fixed at an upstream location, 8 km from the dam, and its detection beam capacity was approximately one third of the river's cross sectional area. In addition to the time of year, the upstream direction, swimming speed limit and fish size range were the specific criteria used from our database to efficiently discriminate other fish species from the Atlantic salmon. Among a total of 116,000 fishes counted during the two periods of investigations, 189 salmon were identified using those criteria. This study enabled us to identify the driving factors that influence the salmon migration in this semi-natural environment. There was a significant difference in fish activity when the dam was operating and when the river flow was under "normal" hydraulic conditions. Furthermore, during the opening and closing phases of the dam, the migration activity was scattered during the day, with peak abundance occurring mainly during the beginning of the operating phases. However, during all valve-opening phases, the salmon activity occurred mainly during the night. Therefore, the results suggest that this dam has a strong influence on fish migration activity at this particular location. (C) 2013 Elsevier Ltd. All rights reserved.

In the laboratory, we studied the impact of pCO2 (3540, 1338 and 541μatm) on the physiology of pearl oysters exposed for 100 days. This experiment was repeated after an interval of one year. Several physiological compartments were examined in pearl oysters: the scope for growth by measuring ingestion, assimilation and oxygen consumption, gametogenesis by means of histological observations, shell growth by measurement and observation by optical and electronic microscopy, and at molecular level by measuring the expression of nine genes of mantle cells implied in the biomineralisation process. Results from both experiments showed that high pCO2 had no effect on scope for growth and gametogenesis. High pCO2 (3540 μatm) significantly slowed down the shell deposit rate at the ventral side and SEM observations of the inside of the shell found signs of chemical dissolution. Of the nine examined genes high pCO2significantly decreased the expression level of one gene (Pmarg-PUSP 6). This study showed that shell growth of the pearl oyster would be slowed down without threatening the species since the management of energy and reproduction functions appeared to be preserved. Further investigations should be conducted on the response of offspring to acidification. International audience

Scorpaena notata is a small, sedentary scorpaenid species widely distributed in the Mediterranean and adjacent waters of the Atlantic. In the western Mediterranean it inhabits coastal continental shelf bottoms. In the Balearic Islands, these bottoms are characterised by the presence of the facies with red algae, including both Peyssonnelia and mäerl beds. These beds enhance the structural complexity, biodiversity and secondary production of the soft bottoms. Due to the oceanographic conditions of the Islands, the facies with red algae are especially rich in terms of biomass and algal coverage, and are widespread distributed between 40 and 90 m depth, where trawlers exploiting the continental shelf operate. The present work studies the biology of S. notata and its relationship with habitat characteristics. Special attention is focused on the aspects related to fish condition and growth as a tool to assess the importance of the facies with red algae for fish. The reproduction period of S. notata in the Balearic Islands occurs in summer and is accompanied by a decrease in hepatic condition, as it happens in the adjacent area off the Iberian Peninsula; however, in contrast with this adjacent area, this period is accompanied by a decrease in somatic condition and an increase in feeding potential, which suggests that these could be adaptations to the higher oligotrophy of the Archipelago. The standardised algal biomass (mostly Rhodophyceae) present in the bottoms positively affected the abundance, somatic condition and feeding potential of S. notata. Individuals inhabiting bottoms with the highest algal biomass showed faster growth than the entire population analysed together. Both, the structural complexity and the availability of preys in the facies with red algae are revealed as advantageous traits for the life history of fish. Taking into account the importance of individual health for the overall success of the population, the indexes studied here could be a useful tool for identifying high quality or essential fish habitats. Our results highlight the importance of the facies with red algae as oasis of high productivity where benthic fish can circumvent the general oligotrophic conditions of the Mediterranean, and the necessity of urgent management measures in order to protect them from human impacts.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2018Publisher:Elsevier BV Authors: Julia Lübbers; Joachim Schönfeld;Julia Lübbers; Joachim Schönfeld;Abstract This study reports for the first time boreal to subarctic intertidal foraminiferal assemblages from saltmarshes at Borgarnes and Faskrudsfjordur on Iceland. The composition of living and dead foraminiferal assemblages was investigated along transects from the tidal flat to the highest reach of halophytic plants. The foraminiferal assemblages from Borgarnes showed 18 species in the total foraminiferal assemblage of which only 7 species were recorded in the living fauna. The assemblages were dominated by agglutinated taxa, whereas 3 calcareous species were recorded, of which only Haynesina orbicularis was found in the living fauna. The distribution limit of calcifying species corresponds to the lower boundary of the lower saltmarsh vegetation zone. Furthermore, calcareous tests showed many features of dissolution, which is an indication of a carbonate corrosive environment. The species forming the dead assemblages were mainly derived from the ambient intertidal areas and were displaced by tidal currents into the saltmarsh. The foraminiferal assemblages from Faskrudsfjordur showed two species, of which only one species was recorded in the living fauna. The assemblage was dominated by the agglutinated foraminifer Trochaminita irregularis. The foraminiferal species recorded on Iceland were the same as commonly found elsewhere in Europa. Since no species was found which is endemic to North America, Iceland is considered part of the European bio province. The foraminiferal could have been immigrated to Iceland from Europe through warm water currents, migratory birds or marine traffic since the last Ice Age.

Single pressures are rare and, in the future, models must be able to examine multiple factors affecting living marine resources such as interactions between: i) climate-driven changes in temperature regimes and acidification, ii) reductions in water quality due to eutrophication, iii) the introduction of alien invasive species, and/or iv) (over-)exploitation by fisheries. Statistical (correlative) approaches can be used to detect historical patterns which may not be relevant in the future. Advancing predictive capacity of changes in distribution and productivity of living marine resources requires explicit modelling of biological and physical mechanisms. New formulations are needed which (depending on the question) will need to strive for more realism in ecophysiology and behaviour of individuals, life history strategies of species, as well as trophodynamic interactions occurring at different spatial scales. Coupling existing models (e.g. physical, biological, economic) is one avenue that has proven successful. However, fundamental advancements are needed to address key issues such as the adaptive capacity of species/groups and ecosystems. The continued development of end-to-end models (e.g., physics to fish to human sectors) will be critical if we hope to assess how multiple pressures may interact to cause changes in living marine resources including the ecological and economic costs and trade-offs of different spatial management strategies. Given the strengths and weaknesses of the various types of models reviewed here, confidence in projections of changes in the distribution and productivity of living marine resources will be increased by assessing model structural uncertainty through biological ensemble modelling. The research leading to these results has received funding from the European Union's Seventh Framework Programme for research, technological development and demonstration (FP7/2007-2013) within the Ocean of Tomorrow call under Grant Agreement No.266445 for the project Vectors of Change in Oceans and Seas Marine Life, Impact on Economic Sectors (VECTORS).

This was revealed by direct turgor pressure measurements and by chemical analyses of osmotic solutes after exposure of upper and lower shore Cladophora to the different salinity regimes occurring in the intertidal zone or representing steady state osmotic acclimation. The main internal osmotic solutes were K + , Cl − , amino acids, NO 3 − and glycine betaine. Na + , SO 4 2− and PO 4 3− were of less importance. The sum of the charges on the cations was similar to that for the anions. K + , Cl − and, to a lesser extent, amino acids were responsible for limited turgor pressure adjustment which did occur. The concentrations of the major osmotic solutes were influenced not only by salinity but also by light: those of amino acids and NO 3 − were increased while those of K + and Cl − were decreased under illumination. Cladophora populations from the upper and lower shore differed in their ability to restore internal K + and Cl − levels on transfer to full seawater after long term exposure to low salinity. This may indicate ecotypic variation.

All show clear evidence of mid-estuarine barium concentration maxima, although the location and scale of these maxima vary. These differences are rationalized in terms of low-salinity desorption of particulate barium, estuarine particle dynamics, riverine sediment supply and barium storage and subsequent slow release in salt marshes. Low-salinity removal of barium also occurs in some estuaries, apparently related to dissolved iron and manganese removal.

Meadows; David S. Limpenny; Hubert I Rees;Abstract A survey was conducted in the eastern English Channel to investigate the use of sidescan sonar, used in conjunction with traditional biological sampling methods, to map the variety and distribution of benthic biotopes (i.e. sea bed habitats and their associated biological communities). An area of sea-bed, approximately 28 km×12 km in size, offshore from Shoreham, U.K., was surveyed using a digital sidescan sonar system and a mosaic of the output was produced covering 100% of the survey area. This was used to divide the area into acoustically distinct regions, around which subsequent benthic ground-truth surveys were designed. Benthic communities and sediment types within each of the these regions were sampled using a Hamon grab fitted with a video camera, and using a heavy duty 2-m beam trawl. Further information concerning the sea-bed was obtained through the application of additional video and photographic techniques. Substrates within each acoustic region were generally homogeneous in distribution, and sediment types ranged across the survey area from cobbles and coarse gravel through to muddy sands. Analysis of the faunal data revealed the presence of statistically distinct biological assemblages within most of the acoustic regions, although species similarity between samples collected from within each acoustic area was often low. Using a combination of all the data sets, five discrete biotopes could be identified and mapped across the area. The application of acoustic techniques, used in conjunction with biological sampling techniques, to map the distribution of sea-bed habitats and associated benthic communities is discussed.

The Adra River deltaic system, southeast Iberian Peninsula, shows a steep topography and is subjected to strong climatic seasonality. This system has been affected by alternating wet and dry periods, and it has also undergone numerous anthropogenic activities such as deforestation, mining activities, river channel deviations and dam construction, particularly during the last two centuries. Two sediment cores were retrieved off the Adra River, from the western (MS_V9) and eastern (MS_V4) lobes of the subaqueous deltaic deposit. A multi-proxy study was carried out, including grain size, benthic foraminiferal assemblages, magnetic susceptibility and geochemical element analyses, in order to understand the sedimentary expression of recent climatic cycles and anthropogenic interventions in the river basin. Periods of increased deposition of coarse-grained sediments, low absolute abundance of benthic foraminifera and high elemental ratios indicative of terrigenous contributions, were interpreted as periods of increased sediment supply to the shelf. Four flooding events were recorded in core MS_V9 and three events on core MS_V4, of which two were observed in both cores. They were related to periods with major floods that were documented on the southern Iberian Peninsula around 1770e1810 and 1860 e1870 AD. On the other hand, sediment core intervals exhibiting increasing proportion of fine-grained sediments and higher abundances of foraminiferal species assigned as successful colonizers (Textularia earlandi) and opportunistic species that feed on bacteria or terrestrial organic matter (Bolivina ordinaria, Bulimina elongata, Eggerelloides scaber and Ammonia beccarii or tepida), indicate the establishment of new environments with new ecological constraints. They were related to significant decreases of terrigenous sediment input during low rainfall or dry periods. The increase of opportunistic species feeding on fresh phytodetritus (Nonionella iridea, Nonionella stella, Nonionella sp., Brizalina dilatata, Epistominella vitrea and Bolivinellina pseudopuntata), under more stable environmental conditions, also point to a stronger marine influence on the prodeltaic environments during these periods. The human interventions on the river basin after 1872 AD, with the deviation of the main river channel to the east, led to a drastic reduction of the sediment exported to the western delta lobe. This study showed that the sedimentation on the Adra subaqueous deltaic deposit was mainly controlled by rainfall variability from 1663 to 1872 AD, and afterwards by anthropogenic interventions. SI

C, N, P and Si in dissolved, particulate, organic and inorganic forms, determined from 12 surveys in the river Oitabén-Verdugo during 2002, allowed quantification of the chemical composition, phase partitioning and fluxes of continental materials to the inner Ría de Vigo (NW Spain). Despite the large fluxes normalised to the drainage basin of the river Oitabén-Verdugo (280 mmol C m−2 y−1, 56.5 mmol N m−2 y−1, 1.35 mmol P m−2 y−1, and 61.3 mmol Si m−2 y−1), its reduced dimensions (350 km2) yielded relatively low concentrations of these species. Organic C, N and P represented 62%, 43% and 48% of the total C, N and P fluxes, respectively. About 90% of the organic C and N and 60% of the organic P was in the dissolved form. The chemical composition of the organic materials was compatible with detrital organic matter derived from aquatic plants, phytoplankton and soil leaching but not with unprocessed terrestrial plants. Significant temporal changes were observed in the chemical composition, related to the seasonal cycle of the biological activity in stream waters and soils, as well as the chemical weathering reactions. Spatial differences were due to the contrasting dynamic regime and, likely, the origin of the materials Financial support came from the Spanish ‘Ministerio de Educacio´ n y Ciencia’ (MEC) grant n REN2000-0880-C02-01 MAR and the ‘Xunta de Galicia’ (XUGA) grant n PGIDT01MAR40201PN.

This paper shows that this dam has an impact on Atlantic salmon (Salmo salar) migration and that adult fish experience adaptive responses. Upstream migration activities were recorded with a 70 kHz echosounder (SIMRAD EY500 model) during two monitoring programs in 2010 and 2011, combining a total of 172 days of data collection. The echosounder was fixed at an upstream location, 8 km from the dam, and its detection beam capacity was approximately one third of the river's cross sectional area. In addition to the time of year, the upstream direction, swimming speed limit and fish size range were the specific criteria used from our database to efficiently discriminate other fish species from the Atlantic salmon. Among a total of 116,000 fishes counted during the two periods of investigations, 189 salmon were identified using those criteria. This study enabled us to identify the driving factors that influence the salmon migration in this semi-natural environment. There was a significant difference in fish activity when the dam was operating and when the river flow was under "normal" hydraulic conditions. Furthermore, during the opening and closing phases of the dam, the migration activity was scattered during the day, with peak abundance occurring mainly during the beginning of the operating phases. However, during all valve-opening phases, the salmon activity occurred mainly during the night. Therefore, the results suggest that this dam has a strong influence on fish migration activity at this particular location. (C) 2013 Elsevier Ltd. All rights reserved.

In the laboratory, we studied the impact of pCO2 (3540, 1338 and 541μatm) on the physiology of pearl oysters exposed for 100 days. This experiment was repeated after an interval of one year. Several physiological compartments were examined in pearl oysters: the scope for growth by measuring ingestion, assimilation and oxygen consumption, gametogenesis by means of histological observations, shell growth by measurement and observation by optical and electronic microscopy, and at molecular level by measuring the expression of nine genes of mantle cells implied in the biomineralisation process. Results from both experiments showed that high pCO2 had no effect on scope for growth and gametogenesis. High pCO2 (3540 μatm) significantly slowed down the shell deposit rate at the ventral side and SEM observations of the inside of the shell found signs of chemical dissolution. Of the nine examined genes high pCO2significantly decreased the expression level of one gene (Pmarg-PUSP 6). This study showed that shell growth of the pearl oyster would be slowed down without threatening the species since the management of energy and reproduction functions appeared to be preserved. Further investigations should be conducted on the response of offspring to acidification. International audience

Scorpaena notata is a small, sedentary scorpaenid species widely distributed in the Mediterranean and adjacent waters of the Atlantic. In the western Mediterranean it inhabits coastal continental shelf bottoms. In the Balearic Islands, these bottoms are characterised by the presence of the facies with red algae, including both Peyssonnelia and mäerl beds. These beds enhance the structural complexity, biodiversity and secondary production of the soft bottoms. Due to the oceanographic conditions of the Islands, the facies with red algae are especially rich in terms of biomass and algal coverage, and are widespread distributed between 40 and 90 m depth, where trawlers exploiting the continental shelf operate. The present work studies the biology of S. notata and its relationship with habitat characteristics. Special attention is focused on the aspects related to fish condition and growth as a tool to assess the importance of the facies with red algae for fish. The reproduction period of S. notata in the Balearic Islands occurs in summer and is accompanied by a decrease in hepatic condition, as it happens in the adjacent area off the Iberian Peninsula; however, in contrast with this adjacent area, this period is accompanied by a decrease in somatic condition and an increase in feeding potential, which suggests that these could be adaptations to the higher oligotrophy of the Archipelago. The standardised algal biomass (mostly Rhodophyceae) present in the bottoms positively affected the abundance, somatic condition and feeding potential of S. notata. Individuals inhabiting bottoms with the highest algal biomass showed faster growth than the entire population analysed together. Both, the structural complexity and the availability of preys in the facies with red algae are revealed as advantageous traits for the life history of fish. Taking into account the importance of individual health for the overall success of the population, the indexes studied here could be a useful tool for identifying high quality or essential fish habitats. Our results highlight the importance of the facies with red algae as oasis of high productivity where benthic fish can circumvent the general oligotrophic conditions of the Mediterranean, and the necessity of urgent management measures in order to protect them from human impacts.

The composition of living and dead foraminiferal assemblages was investigated along transects from the tidal flat to the highest reach of halophytic plants. The foraminiferal assemblages from Borgarnes showed 18 species in the total foraminiferal assemblage of which only 7 species were recorded in the living fauna. The assemblages were dominated by agglutinated taxa, whereas 3 calcareous species were recorded, of which only Haynesina orbicularis was found in the living fauna. The distribution limit of calcifying species corresponds to the lower boundary of the lower saltmarsh vegetation zone. Furthermore, calcareous tests showed many features of dissolution, which is an indication of a carbonate corrosive environment. The species forming the dead assemblages were mainly derived from the ambient intertidal areas and were displaced by tidal currents into the saltmarsh. The foraminiferal assemblages from Faskrudsfjordur showed two species, of which only one species was recorded in the living fauna. The assemblage was dominated by the agglutinated foraminifer Trochaminita irregularis. The foraminiferal species recorded on Iceland were the same as commonly found elsewhere in Europa. Since no species was found which is endemic to North America, Iceland is considered part of the European bio province. The foraminiferal could have been immigrated to Iceland from Europe through warm water currents, migratory birds or marine traffic since the last Ice Age.

Single pressures are rare and, in the future, models must be able to examine multiple factors affecting living marine resources such as interactions between: i) climate-driven changes in temperature regimes and acidification, ii) reductions in water quality due to eutrophication, iii) the introduction of alien invasive species, and/or iv) (over-)exploitation by fisheries. Statistical (correlative) approaches can be used to detect historical patterns which may not be relevant in the future. Advancing predictive capacity of changes in distribution and productivity of living marine resources requires explicit modelling of biological and physical mechanisms. New formulations are needed which (depending on the question) will need to strive for more realism in ecophysiology and behaviour of individuals, life history strategies of species, as well as trophodynamic interactions occurring at different spatial scales. Coupling existing models (e.g. physical, biological, economic) is one avenue that has proven successful. However, fundamental advancements are needed to address key issues such as the adaptive capacity of species/groups and ecosystems. The continued development of end-to-end models (e.g., physics to fish to human sectors) will be critical if we hope to assess how multiple pressures may interact to cause changes in living marine resources including the ecological and economic costs and trade-offs of different spatial management strategies. Given the strengths and weaknesses of the various types of models reviewed here, confidence in projections of changes in the distribution and productivity of living marine resources will be increased by assessing model structural uncertainty through biological ensemble modelling. The research leading to these results has received funding from the European Union's Seventh Framework Programme for research, technological development and demonstration (FP7/2007-2013) within the Ocean of Tomorrow call under Grant Agreement No.266445 for the project Vectors of Change in Oceans and Seas Marine Life, Impact on Economic Sectors (VECTORS).

This was revealed by direct turgor pressure measurements and by chemical analyses of osmotic solutes after exposure of upper and lower shore Cladophora to the different salinity regimes occurring in the intertidal zone or representing steady state osmotic acclimation. The main internal osmotic solutes were K + , Cl − , amino acids, NO 3 − and glycine betaine. Na + , SO 4 2− and PO 4 3− were of less importance. The sum of the charges on the cations was similar to that for the anions. K + , Cl − and, to a lesser extent, amino acids were responsible for limited turgor pressure adjustment which did occur. The concentrations of the major osmotic solutes were influenced not only by salinity but also by light: those of amino acids and NO 3 − were increased while those of K + and Cl − were decreased under illumination. Cladophora populations from the upper and lower shore differed in their ability to restore internal K + and Cl − levels on transfer to full seawater after long term exposure to low salinity. This may indicate ecotypic variation.

All show clear evidence of mid-estuarine barium concentration maxima, although the location and scale of these maxima vary. These differences are rationalized in terms of low-salinity desorption of particulate barium, estuarine particle dynamics, riverine sediment supply and barium storage and subsequent slow release in salt marshes. Low-salinity removal of barium also occurs in some estuaries, apparently related to dissolved iron and manganese removal.

Meadows; David S. Limpenny; Hubert I Rees;Abstract A survey was conducted in the eastern English Channel to investigate the use of sidescan sonar, used in conjunction with traditional biological sampling methods, to map the variety and distribution of benthic biotopes (i.e. sea bed habitats and their associated biological communities). An area of sea-bed, approximately 28 km×12 km in size, offshore from Shoreham, U.K., was surveyed using a digital sidescan sonar system and a mosaic of the output was produced covering 100% of the survey area. This was used to divide the area into acoustically distinct regions, around which subsequent benthic ground-truth surveys were designed. Benthic communities and sediment types within each of the these regions were sampled using a Hamon grab fitted with a video camera, and using a heavy duty 2-m beam trawl. Further information concerning the sea-bed was obtained through the application of additional video and photographic techniques. Substrates within each acoustic region were generally homogeneous in distribution, and sediment types ranged across the survey area from cobbles and coarse gravel through to muddy sands. Analysis of the faunal data revealed the presence of statistically distinct biological assemblages within most of the acoustic regions, although species similarity between samples collected from within each acoustic area was often low. Using a combination of all the data sets, five discrete biotopes could be identified and mapped across the area. The application of acoustic techniques, used in conjunction with biological sampling techniques, to map the distribution of sea-bed habitats and associated benthic communities is discussed.

The Adra River deltaic system, southeast Iberian Peninsula, shows a steep topography and is subjected to strong climatic seasonality. This system has been affected by alternating wet and dry periods, and it has also undergone numerous anthropogenic activities such as deforestation, mining activities, river channel deviations and dam construction, particularly during the last two centuries. Two sediment cores were retrieved off the Adra River, from the western (MS_V9) and eastern (MS_V4) lobes of the subaqueous deltaic deposit. A multi-proxy study was carried out, including grain size, benthic foraminiferal assemblages, magnetic susceptibility and geochemical element analyses, in order to understand the sedimentary expression of recent climatic cycles and anthropogenic interventions in the river basin. Periods of increased deposition of coarse-grained sediments, low absolute abundance of benthic foraminifera and high elemental ratios indicative of terrigenous contributions, were interpreted as periods of increased sediment supply to the shelf. Four flooding events were recorded in core MS_V9 and three events on core MS_V4, of which two were observed in both cores. They were related to periods with major floods that were documented on the southern Iberian Peninsula around 1770e1810 and 1860 e1870 AD. On the other hand, sediment core intervals exhibiting increasing proportion of fine-grained sediments and higher abundances of foraminiferal species assigned as successful colonizers (Textularia earlandi) and opportunistic species that feed on bacteria or terrestrial organic matter (Bolivina ordinaria, Bulimina elongata, Eggerelloides scaber and Ammonia beccarii or tepida), indicate the establishment of new environments with new ecological constraints. They were related to significant decreases of terrigenous sediment input during low rainfall or dry periods. The increase of opportunistic species feeding on fresh phytodetritus (Nonionella iridea, Nonionella stella, Nonionella sp., Brizalina dilatata, Epistominella vitrea and Bolivinellina pseudopuntata), under more stable environmental conditions, also point to a stronger marine influence on the prodeltaic environments during these periods. The human interventions on the river basin after 1872 AD, with the deviation of the main river channel to the east, led to a drastic reduction of the sediment exported to the western delta lobe. This study showed that the sedimentation on the Adra subaqueous deltaic deposit was mainly controlled by rainfall variability from 1663 to 1872 AD, and afterwards by anthropogenic interventions. SI
