Processed CTD data from all sensors mounted on the rosette from R/V Knorr cruise KN210-04 in the Western Atlantic Ocean between Uruguay and Barbados in 2013 (Deep Atlantic DOM project) | For hydrocasts less than 1000m deep, a Biospherical Instruments QSP-200L4S underwater PAR sensor was attached to the CTD rosette. This sensor was linked to a surface PAR sensor on the ship (QSR-240). | Biospherical Instruments QSP-200L4S underwater PAR sensor |
