Particle birefringence photon yield and particle beam attenuation coefficient derived from optical particle sensors deployed on GTC CTD casts on the U.S. GEOTRACES Pacific Meridional Transect (PMT) cruise (GP15) on R/V Roger Revelle from Sept-Nov 2018

This data set was derived from optical particle sensors deployed during casts of the GEOTRACES Trace Metal Carousel (GTC) as part of the GEOTRACES Pacific Meridional Transect (GP15 expedition). There are several related data files provided. Data files are provided containing the average of all optical data profiles at each station for 0-500 meters (m) depth as well as for the full depth of the water column (6000 meters). CTD data used in the profile data calculations are also provided.
