Description:
The Eddies Dynamics, Mixing, Export, and Species composition (EDDIES) mesozooplankton biomass data set includes estimates of mesozooplankton biomass determined from MOCNESS plankton net tows. Zooplankton biomass estimates were determined from 1 m^2, 150 micron mesh MOCNESS (Multiple Opening/Closing Net and Environmental Sensing System) tows. The following discrete depth intervals were sampled on the upcast: 0-50, 50-100, 100-150, 150-200, 200-300, 300-400, 400-500, 500-600, and 600-700 m. Generally paired tows during the day (9:30-15:00 local time) and night (21:30-03:00) were performed at each station. A single tow generally covered 5-15 km. The nominal position (lat_n and lon_n) for each tow is the position at the mid depth 200-300m sampling interval. Table 1 (pg 1362) of Goldthwait and Steinberg (2008) is a sequential list of all MOCNESS mesozooplankton tows and includes eddy identification number and location. Each sample was size-fractionated using nested sieves of 0.15 mm, 0.5 mm, 1 mm, 2mm, and 5 mm mesh. Zooplankton in each size class were transferred onto pre-weighed 0.15 mm nitex mesh filters and rinsed with deionized water. Samples were then dried for 24 hours at 60 degrees C and weighed.
