UG-MESA Potential Fishing Zone Maps
Description
The PFZ chart is developed from a Generalized Additive Model built from a binomial distribution family with a probit link function. Parameters for developing the model were presence- absence data of fish catch data from logbooks and a suite of environmental datasets covering the equatorial Atlantic. The charts are generated daily with surface temperature (SST), sea surface heights (SSH), geostrophic currents (UV) and salinity (SSS) datasets as inputs into the model. The PFZ chart shows the probability of occurrence of pelagic fish in the equatorial Atlantic. The pixel values range from 0% to 100% which indicates the probability of finding the optimal conditions preferred by pelagic fishes.
