Abstract: An autonomous surface vessel includes an elongate body, and a sampling system operatively coupled to the body and including one or more sampling modules, wherein each sampling module includes a housing including a storage container, a sampling material receivable within the storage container, an actuation system operatively coupled to the sampling material via a lead line, and an end cap operatively coupled to the lead line and matable with an open end of the storage container. A computer system is in communication with the sampling system to operate the actuation system, wherein each sampling module is actuatable between a stowed state, where the sampling material is received within the storage container and the end cap sealingly engages the open end, and a deployed state, where the end cap is disengaged from the open end and the sampling material is drawn out of the sampling container.

Abstract: Detection and sampling of dissolved hydrocarbons of interest in an environment expected to have hydrocarbon molecules, such as a water column or interstitial water in sediment. An apparatus comprising at least one oleophilic film frame is deployed into the environment and the at least one oleophilic film frame is exposed thereto for a defined period of time, and thereafter isolated from the environment to cease exposure thereto. Hydrocarbon molecules scavenged by the oleophilic film may be analyzed to determine their type and/or concentration.
