Designs for an Ocean Floor Sediment Collection Device

Job ID: 33632865

Budget: $290 – $410 USD

ABSTRACT
designs for an automated, inexpensive, underwater sediment collection device for operation in the epipelagic zone of the ocean to a depth of 200 meters. The device must be capable of operation attached to a remotely operated vehicle (ROV) or by a diver with minimal manual intervention. It should weigh (in air) 5 kilograms or less, be capable of collecting samples of clay, silt, and sand while retaining any layering found within the sample, and collect samples to a sediment depth between 300 and 600 millimeters.

This Theoretical Challenge requires only a written proposal.

OVERVIEW

Ocean sediments can affect the performance of sonar systems and other seabed activities. Information on the composition and layer structure of ocean floor sediments from an area of interest may be used during mission planning to account for these effects. Current methods typically utilize divers with hand-held implements to collect material from the ocean floor but this often only leads to general composition information with no layer or structure information due to the nature of the implements used for collection. The US Navy is soliciting designs for an inexpensive, automated underwater sediment collection device that can collect samples of clay, silt, and sand while retaining the layering found within the sample. It must be capable of operating attached to a remotely operated vehicle (ROV) or by a single diver with limited manual intervention and operate to a depth of 200 meters. Designs should include preliminary CAD files and wiring diagrams and be accompanied by a detailed description of the device as well as an operating guide for the proposed device.

This is a Theoretical Challenge that requires only a written proposal to be submitted.
