©2026 Biological and Chemical Oceanography Data Management Office.In May 2024, the R/V Sally Ride cruises SR2406-SR2408 were conducted in the Gulf of California. During SR2408 a set of individuals were collected for a biomass to biovolume comparison for a wide range of oranisms from the region. These samples come from th net 0 (0-1000 m sampling interval) from a pair of day and night tows (moc 9 and moc 10) in Guaymas Basin in the Gulf of California on May 15th. This dataset provides the relationship between size and mass for multiple large taxonomic groups.

Individuals used in the Biovolume to Biomass dataset were collected May 15, 2024 at 26°22.348 N, 110°45.295 W. They were frozen at sea then returned to the lab where they were imaged on a ZooSCAN following the methods described in Maas et al. 2021 to obtain size-related metrics. After imaging each individual was weighed on a Mettler-Toledo XPR microbalance then dried for a minimum of 3 days in a drying oven at 55C. They were then weighed again to obtain dry mass.
