Purpose: We will collect gelatinous organisms, emphasizing depths beyond 1500m. Our target organisms are: ctenophores, siphonophores, radiolarians and squid. Blue-water scuba dives will be conducted each morning except for the first and last days according to standard procedures, weather permitting. Three divers will be present on the ship and paperwork is filed with Kim Reisenbichler. Trawls will be conducted from 2000h to approximately 2300h each night. We will bring the trawl but will need the winch to be set-up and operated. Trawls will generally not be oblique, so dedicated operator time will be mostly during launch and recovery.
