©2020 Biological and Chemical Oceanography Data Management Office.ZooSCAN biovolume to biomass from the Sargasso Sea including locations in the vicinity of the Bermuda Atlantic Time-series Study (BATS). Samples were collected during MOCNESS tows during R/V Atlantic Explorer cruises between 2016 to 2019 (AE1614, AE1712, AE1830, AE1917, AE1918, AE1931) and a few small boat deployments. These data were published in Maas et al. (2021) as Supplementary Table 1.
Methodology: Individual zooplankton of a variety of taxa were individually selected from multiple MOCNESS and Reeve net tows. Organisms were picked from both surface and deep nets and across a range of sizes to represent the full range of potential morphologies. They were imaged on a ZooSCAN ver. 3 at 4,800 dpi (following the methods in: Gorsky et al., 2010, Vandromme et al., 2012). Raw images were then processed in ZooProcess (Gorsky et al., 2010, Vandromme et al., 2012), resulting in a measurement and metadata file. After imaging each individual organism was weighed wet on a Mettler-Toledo XPR microbalance, dried for 3 days in a drying oven at 60 C, and reweighed.
Sampling and analytical procedures: Most samples (all from the MOCNESS) had been preserved in formalin for between 1 and 4 years. Individuals from the Reeve net had been preserved in ethanol or stored at -80C for 1-2 years. All individuals were imaged in DI water at room temperature.
