Period of record is for the first 10 days of operation during a cold front passage.The first day of record for each float ranges from May 2, 2017, to May 7, 2017. Technology for measuring subsurface ocean currents is available using the Autonomous Profiling Explorer floats with electromagnetic sensors (APEX-EM) recently developed by Teledyne Webb Research and the University of Washington. Velocity measurements obtained from electromagnetic current sensor pairs. Given the passage of a strong atmospheric front in May 2017, these data were used in an initial evaluation of the state-of-the-art float and its response to strong wind-driven currents. This float technology enables investigators to look more closely at the upper ocean response to strong forcing events that impact biochemistry and hydrocarbon dispersion. Sampling rates were changed by updating mission profiles from continuous to profiling modes between specific depths by changing the piston counts on the missions via Iridium remote sensing when the float reaches the free surface. unknown Lynn K.
