CTD Data

Environmental parameters collected during conductivity, temperature and depth (CTD) casts typically performed daily at the end of marine mammal visual observations;.

Both processed and unprocessed CTD are provided

main goal is to provide vertical profiles of salinity, temperature, and oxygen content to a maximum depth of 500 m.
