| Summary: | <p>This dataset is the one of several from this project being discovered and rescued and made available on line.</p> <p>These data are zooplankton, specifically euphausiids, collected and identified in the 1980s as part of the warm-core rings multidisciplinary programs. Included are stratified euphausiid species abundance and zooplankton biomass from 100 MOCNESS tows and related metadata taken on 18 research cruises in the Northwest Atlantic. The euphausiid abundance numbers represent numbers per cubic meter in that depth layer. 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.</p> <p><strong>A note about 'nd':</strong> 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'.</p>
