attribute	NC_GLOBAL	comment	String	Zooplankton identification and enumeration from discrete tow samples taken at deployments and recoveries of gliders often equipped with an on-board ASL Acoustic Zooplankton Fish Profiler (AZFP) multi-frequency echo sounder with transducers configured for zooplankton (120, 200, 455 and 769 kHz). Zooplankton were collected aboard the vessel at glider deployment and recovery by performing replicate oblique tows from the surface to approximately 5 m above the seafloor with a 0.25 m^2, 200 micron mesh net with filtering cod-end and preserved in 10% buffered formalin. Net depth was estimated using wire angle and length of wire until April 2025 when the depth was measured using a HOBO Titanium 250-Foot Depth Water Level Data Logger attached to the net. In the lab, each tow was split to obtain a representative sample, and individual zooplankton were identified to lowest feasible taxonomic group and counted using a dissecting stereo microscope.

attribute	NC_GLOBAL	summary	String	This project is conducting a seasonal baseline survey with a pair of underwater Slocum gliders deployed in each season with a full complement of available sensors to simultaneously map oceanographic and ecological variables. Zooplankton samples were taken during glider deployments and recoveries. When a zooplankton-configured ASL Acoustic Zooplankton Fish Profiler (AZFP) was on board the glider, these samples were used to ground-truth the glider-based acoustic zooplankton concentration and biomass estimates. Full-resolution quality-controlled glider datasets and associated raw and processed acoustic data are archived at National Centers for Environmental Information (NCEI)'s Water Column Sonar Data repository https://www.ncei.noaa.gov/products/water-column-sonar-data. Full-resolution raw glider datasets that do not contain the acoustic data can be downloaded at https://slocum-data.marine.rutgers.edu/erddap/index.html.
