MOCNESS profile and ichthyoplankton and decapod specimen identification data collected during NRDA Plankton Survey Nick Skansi 9 (NS9) in the northern Gulf of Mexico from 2011-04-17 to 2011-06-26 (NCEI Accession 0239999)

This data package contains MOCNESS (Multiple Opening/Closing Net Environmental Sensing System) profile data and other ichthyoplankton and decapod data collected during Natural Resource Damage Assessment (NRDA) Plankton Survey Nick Skansi 9 (NS9) in the Gulf of Mexico from 2011-04-17 to 2011-06-26. This survey was part of a series of NS NRDA cruises conducted in 2010 and 2011 to evaluate the distribution and densities of ichthyoplankton and other zooplankton in northern Gulf of Mexico waters potentially affected by the Deepwater Horizon Oil Spill (DWHOS). The data package includes the original profile data representing environmental samples (e.g., temperature, salinity, pressure) for individual MOCNESS tows as well as combined and summary data (all tows) for the full cruise. Dataset also includes sampling event data (e.g., time, latitude, longitude, depth, volume filtered) and specimen data (e.g., taxonomic identification, length, number of individuals).
