Abstract

This is the log for the trace metal rosette niskin bottles deployed on the R/V Atlantis CliOMZ AT50-10 expedition from Golfito Costa Rica to San Diego USA that occurred in May - June of 2023. The log contains metadata associated with each rosette deployment, including location, bottle depth, and time. The rosette was launched on 1/4" kevlar line spooled on a MASH2K winch from the East Coast Winch Pool. The Science party included members from WHOI, UCSB, UTGRV, and Clark University.

Data was logged and collected from Trace Metal Clean Rosette (TMR) deployments during reseach cruise AT50-10. The TMR was deployed on a non-conducting 1/4" Kevlar line and preprogrammed to trip at pre-determined depths on the upcast. 

Sampling was conducted using a Trace Metal Clean Rosette (TMR) outfitted with X-Niskin bottles and physicochemical parameters were measured using a mounted Sea-Bird SEACAT 19+. The TMR was deployed on a MASH-2K winch from the UNOLS East Coast Winch Pool.
