The data processing methodology is as described in Li, et al. (2025) and in Bishop, et al. (2022). Processing code logic was finalized in August 2024.
===========
Processing logic:

# CST1450 Processing

# cst1450c=(cst1450-cst1450z)/cst1450r - cum1450dr - cst1450t*0.3
# tr=cst1450c/CST1450_NetVref
# cp1450_sd=-4*ln((CST1450_NetVref-cst1450_sd)/CST1450_NetVref)
# cp1450=-4*ln(tr)
#
# PIC011 processing
# prc=-PIC011_PRcoefft*press ! pressure correction
# drc=PIC011_driftMULT*cum1450dr ! drift correction
# tmc=pic011t*PIC011t_Mult ! thermal shock correction
#
# pic011zc=pic011-PIC011_z
# pic011cc=(pic011zc-PIC011_NETcross*tr)/pic011r
# adjpic=drc+tmc
# pic011p=(pic11-adjpic)/tr^0.5+prc
# pic011Biref=pic011p*PIC011_BIREF
# pic011Biref_sd=picuse_sd*644.4
#
# Fluorometer Processing
# chl_flwl=(flwlv-Flwl_z)*Flwl_Mult
# chl_flwl_sd=(0.02^2+(Flwl_Mult*flwlv_sd)^2)^0.5
# chl_flwl_n=flwlv_n
#
# Turbitity Processing
# mFTU=(seapoint-seapoint_Z)*5000
# mFTU_sd=seapoint_sd*5000
# mFTU_n=seapoint_n

16:T5d1,This dataset was derived from optical particle sensors interfaced to a logging CTD and deployed during McLane Pump casts of the as part of the GEOTRACES GP17-OCE Expedition from the south Pacific gyre to Southern Ocean (R/V Roger Revelle RR2214). Data files are provided containing data for the 0-500 meter depth interval and also for the full water column. Files include measures of particle birefringence photon yield (units of parts per million per meter) and particle beam attenuation coefficient (units of per meter), scattering (units of mFTU), and chlorophyll estimated from fluorescence readings. Note McLane CTD scatting profiles are available only at GP17-OCE stations 1, 3, 6, 8, 12, and 14. The two PIC sensors (PIC010, and PIC011) used in this study have been extensively documented (Bishop et al.
