©2020 Biological and Chemical Oceanography Data Management Office.This dataset contains estimates of Euphotic Zone (EZ) depths based on mean light extinction coefficients calculated from PAR sensor readings at 5 and 100 meters from cruise RR2201 on R/V Roger Revelle (BLOOFINZ-IO, January-March 2022) in the Argo Basin region off NW Australia.
Euphotic Zone (EZ) depth was defined as the depth at which photosynthetically available radiation (PAR) was 1% of incident surface radiation. Mean light extinction coefficients (Ext Coeff, m-1) were calculated from PAR sensor readings at 5 and 100 meters from CTD downcast profiles at 1-meter resolution according to the equation:
Ext Coeff = -ln(PAR100m/PAR5m)/95.
Euphotic Zone (m) was calculated as EZ = -ln(0.01)/(Ext Coeff).
