Physical and biogeochemical CTD, ADCP, and towed vehicle data collected for the Mechanisms Controlling Hypoxia Project in the northern Gulf of Mexico from 2010-04-06 to 2014-08-12 (NCEI Accession 0240146)

The physical and biogeochemical processes that control and maintain the hypoxic zone in the northern Gulf of Mexico are complex and their relative strengths are known to vary temporally and spatially at many scales. The MCH Project was funded by NOAA from 2003-2016 and consisted of an integrated observational and numerical modeling approach to better understand the interactions of the physical, biological, and geochemical processes and their variability across the entire Texas/Louisiana shelf. This information contributes to a comprehensive description of the mechanisms that control hypoxia in the northern Gulf of Mexico. Environmental and oceanographic observations were recorded on 31 process-oriented research cruises and resulted in more than 120 towed transects, ~5000 CTD casts, ~30000 water samples, and more than 50000 km of ship flow-through system data. The data represented in this submission account for 15 research cruises and is the second of two submissions to NCEI; access to first submission is Accession 0088164.
