Dataset: Gulf Stream Warm-Core and Cold-Core Rings integrated Euphausiid abundance and zooplankton biomass from multiple cruises in the North Atlantic from 1972-1982 (NAtlDarkData project)

     These data are zooplankton collected and identified in the 1970s and 1980s as part of the cold-core and warm-core rings multidisciplinary programs and other related projects. They have been filtered and post-processed. Included are zooplankton biomass and euphausiid species abundance from 306 tows and related metadata taken on 34 research cruises in the Northwest Atlantic.  The zooplankton biomass and euphausiid catch data and the associated environmental information were acquired using ring nets, net systems, and CTD/rosettes (Conductivity-Temperature-Depth) and Niskin bottles. Ring net, Bongo net and MOCNESS (Multiple Opening and Closing Nets and Environmental Sensing Systems)  tows were quantified using flow meters calibrated to provide volumes of water filtered for each tow.

A note about 'nd':  Traditionally 'nd' is taken to mean 'no data'.  Within that meaning, however, there is much variability.  Here 'nd' could mean the more traditional 'we tried and got bad or no data'.  It could mean 'these data are not considered relevant to the overall effort'.  Finally, 'nd' could mean 'does not exist'.

This particular dataset is a re-display of the dataset Integrated Euphausiid Abundance and Zooplankton Biomass with the individual zooplankton under a general heading of 'species'.
