EM-APEX profiling floats measuring temperature, salinity, horizontal currents, and turbulence are continuing to be deployed into the global Sampling QUantitative Internal-wave Distributions (SQUID) array. This spring, 7 floats were launched from the R/V Marcus G. Langseth in the South Atlantic on GO-SHIP repeat hydrography line A13.5, and another was launched from the R/V Kilo Moana on a short cruise to the Kauai Channel—a key location of past internal wave study in the Hawaii Ocean Mixing Experiment. SQUID floats are characterizing the internal wave energy levels in a range of ocean … Read More
