Zooplankton abundance and population structures were assessed during April-September of 2001-2, Southern Ocean, GLOBEC
Listed in NASA Earthdata CMR
Zooplankton abundance, vertical and horizontal distribution, and population structures were assessed in the area adjacent to the Antarctic Peninsula.
Description
Sampling was conducted during multi-ship surveys, April thru September of 2001-2002, using a m<sup>2</sup> Multiple Opening and Closing Nets and Environmental Sampling System (MOCNESS). In this application, the MOCNESS system consisted of nine nets having 333 µm mesh and environmental sensors of temperature, salinity and depth.
The entire water column was sampled on the downcast using net # 0, this sample is not reported here. The water column was typically sampled from close to the bottom at stations on the shelf where depths were less than 1000 m, or to 1000 m at stations off the shelf where depths were often from 3000 to 4000 m. Nets 1 through 8 sampled from various depth intervals to the surface with smaller strata near the surface.

Several tows targeted krill swarms by towing in a single strata. Zooplankton samples sorted to species, life stage and size class. Ship Cruises: cruise / cruise id / dates Nathaniel B.
