Data and Code Associated with Publication "Current Marine Protected Areas conserve fish spawning aggregations under climate change due to habitat refugia"
(2025-07-27) Bartlett, Brian S.; Asch, Rebecca
"This dataset includes all bias-corrected climatological data, Nassau grouper spawning aggregation data, reef shape data and MPA border data used in ""Paper Title"". This repository also contains the species distribution model (NPPEN) code used to analyze this data in Matlab. These datasets were input for the NPPEN model, described in the paper, under various time periods and RCP scenarios.
Climatological data is organized as MODEL_timeperiod_variable.csv. Each file consists of 14 columns, with columns 1 and 2 representing latitude and longitude respectively. Columns 3-14 represent the bias-corrected monthly value for that variable (3=January, 4=February… 14=December) etc. Sea Surface Temperature (SST) variables are measured in °C, Seasonal Temperature Gradients (STG) are measured in change in °C/month. North/South geostrophic currents (v) are measured in cm/s. MPA_boundaries.csv lists the northernmost, southernmost, easternmost and westernmost extents of individual MPAs. Pixels_with_reefs.csv provides a 0.5°x0.5° grid with ‘1’s representing pixels in our model region with reefs, and ‘0’s representing the absence of reefs.
NG_spawning_data.csv provides information on Nassau grouper spawning aggregations. Columns 1 and 2 provide latitude and longitude (respectively) data of spawning aggregations, truncated to the nearest 0.1°. Column 3 provides the month of the spawning aggregation. Column 4 provides SST in °C, column 5 provides STG in change °C/month and column 6 provides north/south geostrophic currents in m/s. NPPEN_script_Matlab.rtf provides generalized NPPEN code for matlab, using variables provided."
