Here we quantify the abundance and distribution of three primary permafrost region disturbances (PRD; lakes and their dynamics, wildfires, retrogressive thaw slumps) using trend analysis of 30-m resolution Landsat imagery from 1999-2014 and auxiliary datasets. The datas...

In this study the importance of spatial scales on nematode species distribution and patterns of biodiversity and turnover in cold seeps was investigated. Therefore it was identified how nematode assemblages differ in densities and composition at different spatial scales...

Although anthropogenic infuences such as global warming, overfishing, and eutrophication may contribute to jellyfish blooms, little is known about the effects of ocean acidification on jellyfish. Most medusae form statoliths of calcium sulfate hemihydrate that are compo...

The dataset contains pore water and core incubation silicic acid concentration and isotope measurements, sponge silicon isotope measurements, and pore water major and trace elemental concentrations obtained from seven sediment cores collected from the Greenland margin a...

Swiftia phaeton, a new species, is described for Mauritania where it is endemic at the upper bathyal. This azooxanthellate octocoral is distinctive from congeneric species in the NE Atlantic and Mediterranean Sea by the dark red coloration of the colonies and polyps, th...

This dataset contains major element oxide data of tephra layers from marine sediment core GS16-204-22CC. The core has been investigated for increased tephra occurrences and geochemically analysed for the major element composition of tephra shards to identify their sourc...

Increasing atmospheric carbon dioxide (CO2) concentrations are expectedto decrease surface ocean pH by 0.3-0.5 units by 2100, lowering the carbonate ion concentration of surfacewaters. This rapid acidification is predicted to dramatically decrease calcification in many ...

High acoustic seafloor-backscatter signals characterize hundreds of patches of methane-derived authigenic carbonates and chemosynthetic communities associated with hydrocarbon seepage on the Nile Deep Sea Fan (NDSF) in the Eastern Mediterranean Sea. During a high-resolu...

To understand the response of marine calcifying organisms under high CO2 scenarios, it is critical to study their calcification patterns in the natural environment. This paper focuses on a major calcifying phytoplankton group, the coccolithophores, through the interpret...

Changes in calcification of coccolithophores may affect their photosynthetic responses to both, ultraviolet radiation (UVR, 280-400 nm) and temperature. We operated semi-continuous cultures of Emiliania huxleyi (strain CS-369) at reduced (0.1 mM, LCa) and ambient (10 mM...
