This batch of script reproduces the results of "Watermass characteristics and circulation near 110 °E in the south-east Indian Ocean" research paper. This is written using MATLAB. I have also used M_Map(A mapping package for MATLAB) version 1.4m, GSW Oceanographic Toolbox and J.M.Lilly toolbox to save figures. For more information, tutorial and the details of the analysis please see our paper https://doi.org/10.1016/j.dsr2.2022.105149.

To overcome the cost of competition resulting from foraging socially, individuals may balance their use of private (i.e. acquired from personal sampling) and social (i.e. acquired by watching other individuals) information to adjust their foraging strategy accordingly. Reliability of private information about environmental characteristics, such as the spatial distribution of prey, is thus likely to affect individual movement and social interactions. We aimed to investigate how movement characteristics of foraging individuals changed as they acquired reliable information about the spatial occurrence of prey in a foraging context. We allowed guppies (Poecilia reticulata) to develop the reliability of their private knowledge about prey spatial occurrence by repeatedly testing shoals in a foraging task under three experimental distributions of prey: 1) aggregated prey forming three patches located in fixed locations, 2) scattered distribution of prey with random locations, or 3) no prey (used as control). Using individual time series of spatial coordinates, we computed a suite of movement variables reflecting search effort, social proximity and locomotion characteristics during foraging, to examine changes occurring over repeated trials. Over time, individuals foraging on either scattered or aggregated prey travelled greater distances, showed an increasing distance to their closest neighbour and became more stochastic in their acceleration profile, compared to control individuals. We found that behaviour changed as private information increased over time, with a behavioural shift and an increase of collective foraging efficiency occurring on the third testing day. Social proximity was the major predictor of foraging success in the absence of prior foraging information, while search effort became the most important predictors of foraging success as information increased. In conclusion, we show that individual movement patterns changed as they acquired private information. Contrary to our predictions, the spatial distribution of prey did not affect any of the movement variables of interest. This dataset was collected by filming guppy shoals foraging in an experimental arena under laboratory conditions. A number of variables (viz. distance travelled, distance to nearest neighbour, acceleration entropy, time spent grouping, number and duration of grouping events) were computed from the tracking data of the first minute of the foraging trials. Statistical investigations aimed to identify changes in movement characteristics and social interactions occuring over repeated foraging trials. R and Excel are required to access the data files.
