RRS James Clark Ross JR20071212 (JR196 Leg2)
Cruise summary report
|Ship name (ship code)||RRS James Clark Ross (74JC)|
|Cruise identifier||JR20071212 (JR196 Leg2)|
|Cruise period||2007-12-12 — 2007-12-26|
|Port of departure||Rothera, Antarctica|
|Port of return||Stanley, Falkland Islands (Malvinas)|
|Objectives||The principal objective is to study variations in the flow of the Antarctic Circumpolar Current (ACC) on large time and space scales; however the ACCLAIM network is also a component of GLOSS (Global Sea Level Observing System). The BPRs have supplied sea level data that providing knowledge of tidal behaviour in this remote area.
ACCLAIM Bottom Pressure Recorders have been deployed since 1988, initially in the Scotia Sea and then later in the Drake Passage. The data is made available to the international research community through the Permanent Service for Mean Sea Level (PSMSL).
1) Service the Sea Level Recorder at Port Stanley, Falkland Islands.
2) Install a Meteosat Tide Gauge system and replace the existing Orbcomm system at Port Stanley, Falkland Islands.
3) Deploy two BPR's in the Drake Passage.
4) Service and repair the Sea Level Recorder at Vernadsky Antarctic Research Station.
5) Service the Sea Level Recorder at Rothera Antarctic Research Station.
6) Install a PORTUX base communication system to replace the existing GUMSTIX equipment again at Rothera Antarctic Research Station.
7) Collect downloaded data from the Signy Gauge and check installation
8) Supply and repair tide gauge equipment at King Edward Point Antarctic Research Station.
