The targeted area of the ballasted float deployments lies between the DeSoto Canyon and the northern extent of the Loop Current in the eastern Gulf of Mexico. The EM-APEX profiling float is equipped with Conductivity, Temperature, Depth (CTD) and electromagnetic current sensors and also measures the following biochemical properties: dissolved oxygen (DO), chlorophyll fluorescence as proxy for phytoplankton abundance, backscatter as proxy of particle concentration (including marine particles and oil droplets), and colored dissolved organic matter (CDOM) fluorescence as proxy of CDOM (including fluorophoric oil components). Floats were deployed in May 2017 and transmitted data for nearly two years. Lynn K.
