Scientific sampling event log from the US GEOTRACES Pacific Meridional Transect (PMT) cruise (GP15) from September to November 2018

Abstract:

Scientific sampling event log from the US GEOTRACES Pacific Meridional Transect (PMT) cruise (GP15) from September to November 2018. GP15 was carried out on the R/V Roger Revelle and was split into two legs: RR1814 (Seattle, WA to Hilo, HI) and RR1815 (Hilo, HI to Papeete, French Polynesia).
