PurposeResearch
ObjectivesThree different cruises are described in this report: ES031, ES038 and ES048. ES048 covers the LTMS-P work around the South Orkneys, in collaboration with Lamont-Doherty Earth Observatory (Columbia University, New York), ES038 was to be for LTMS-P work at the Filcher Sill, in collaboration with Bjerknes Centre for Climate Research (Bergen), southern Weddell Sea, and ES031 was to serve the ACES-FOCAS project, again in the southern Weddell Sea. In cooperation with the Alfred-Wegener-Institut für Polar- und Meeresforschung, Bremerhaven (AWI) a mooring programme was carried out to extend the location facilities for the Weddell Sea under ice float programme.

In the event, sea ice conditions prevented ES038 from being accomplished: on two different attempts the ship encountered ten-tenths pack ice west of 031W at the latitude of the mooring locations, with giant floes entirely stopping further progress westwards.

Despite very heavy sea ice, the majority of ES031 was achieved. The location of one of the moorings was again too far to the west to be accessed, and, in any case, the malfunction of one of the six Ixsea releaser units would have prevented its deployment. Some of the CTD sections that were to extend to the north and west also had to be shortened because of the sea ice conditions. The available time was spent undertaking a details hydrographic survey around, and to the north of Brunt Ice Shelf, a survey that will contribute directly to the ACES-FOCAS project. The final element of ES031 was the tagging of seals, in collaboration with the Sea Mammal Research Unit of St Andrews University. Four CTD tags were successfully deployed on Weddell seals near Helmert Bank, at the eastern Filchner Sill. A fifth tag was deployed on a male Elephant seal on Signy Island.
