Dataset: Cold core rings stratified euphausiid abundance and biomass (carbon) from multiple cruises in the N. Atlantic, 1973 - 1977

This dataset is the one of several from this project discovered, rescued, and made available online.

These data are zooplankton, specifically euphausiids, collected and identified in the 1970s as part of the cold-core rings multidisciplinary program.  Included are stratified euphausiid species abundance and zooplankton biomass from over 100 MOCNESS tows and related metadata taken on 9 research cruises in the Northwest Atlantic.  The euphausiid abundance numbers represent numbers per cubic meter in each depth layer. MOCNESS (Multiple Opening and Closing Nets and Environmental Sensing Systems) tows were quantified using flow meters calibrated to provide the volume 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'.
