Typical missions of the 329 feet T-AGS 60 vessels may include oceanographic sampling and data collection of surface water, mid-water and ocean floor parameters; the launch and recovery of small boats known as hydrographic survey launches (HSLs); the launching, recovering and towing of scientific packages (both tethered and autonomous) including the handling, monitoring and servicing of remotely operated vehicles (ROVs); shipboard oceanographic data processing and sample analysis; and precise navigation, trackline maneuvering and station-keeping to support deep-ocean and coastal surveys.
