RRS James Clark Ross

Occupied: 1 December 1990 to present

RRS James Clark Ross (JCR), launched by HM the Queen in 1990, is primarily a marine research vessel for biological, oceanographic and geophysical cruises. It is equipped with a suite of laboratories and winch systems that allows scientific equipment to be deployed astern or amidships. The ship has an extremely low noise signature, allowing the deployment of sensitive acoustic equipment. A swath bathymetry system was fitted in 2000. The JCR also carries out some cargo and logistical work. During the northern summer the JCR supports NERC research, largely in the Arctic.

RRS James Clark Ross (named after Admiral Sir James Clark Ross, R.N.) was built by Swan Hunter Shipbuilders, Wallsend, UK. The vessel can steam at a steady two knots through level sea ice one metre thick. To assist passage through heavy pack ice a compressed air system rolls the ship from side to side freeing the passage.

Researchers describe how they use robotic technologies to measure ice shelves and sea ice.

Purpose

RRS James Clark Ross contains some of Britain’s most advanced facilities for oceanographic research.

The ship is equipped for geophysical studies, with a compressor bank to power a seismic air gun array, and large aft and starboard decks for scientific equipment deployed by aft and midships gantries.

For biological studies, the vessel can deploy a wide range of sampling gear and benefits from modern underway instrumentation.

The ship is designed with an extremely low noise signature to allow sensitive underwater acoustic equipment to operate effectively.
