Abstract:

Deep water sampling of in-situ seawater and associated fauna (cruise DP02, August 8-22, 2015) aboard the R/V Point Sur for an area encompassing roughly 28°N to 29°N and 87.5°W to 88.5°W. Submitted data in this dataset are ADCP, UDAS, Chlorophyll flowthrough data, environmental data, and ship logs. The biological and trawl data collected during this cruise are available in GRIIDC dataset R4.x257.226:0001. The MOCNESS sensor data are available in GRIIDC dataset R4.x257.226:0006.
