Dynamics and Transport of the Antarctic Circumpolar Current in Drake Passage |
The goal of this program is to quantify the transport and understand the dynamical balances of the Antarctic Circumpolar Current (ACC) in Drake Passage. For this purpose we have proposed a transport line and a local dynamics array of CPIES (Current and Pressure recording Inverted Echo Sounders) spanning the predominant along-stream wavelength of 250 km for 4 years. Data will be collected annually by acoustic telemetry, leaving the instruments undisturbed until recovered. |
Project funded and deployment is scheduled on the N.B. Palmer 5-30 November 2007.Dynamics and Transport of the Antarctic Circumpolar Current in Drake Passage |

Cape Adare Long-term Mooring (CALM) |
An array of moorings will be deployed and maintained east of Cape Adare at the northwestern corner of the Ross Sea to observe the properties of AABW exiting the Ross Sea. This location was identified during two of the recent AnSlope expeditions as an ideal place to make such measurements. A single pilot mooring funded by Columbia University was deployed near Cape Adare during the second AnSlope cruise; the proposed moorings will continue the time series begun by that pilot effort. |
This is a three-year pilot phase to demonstrate the feasibility and potential long-term benefits of such a time series in a region of deep- and bottom-water outflow in the Western Ross Sea. |
Data will be made available 2 years after recovery cruise (Feb 08 or 09) |

Orkney Passage Moorings |
These moorings will monitor changes in the speed and properties of AABW as it crosses the ridge from the Weddell Sea into the Scotia Sea, as part of its export into the World Ocean. (Properties measured: temperature, salinity, velocity, pressure.) |

French Drake
Passage moorings.
|
10 current meter moorings were deployed across Drake Passage at T/P altimeter crossover points along the T/P groundtrack 104. Each mooring includes current meters at 500, 1000 and 2500 m.
|
Moorings will be partly replaced by Polarstern in April 2008

biophysical
moorings |
Two biophysical
moorings are currently deployed in STW and SAW water masses at
41ºS and 46º40ºS on
178º30ºE.
The moorings are
located in 2700-3100 m water depths and each comprise sediment trap
and current meters at 1500 m depth, a current meter at 50 m and a
MicroCat (T/S) at 80 m with temperature loggers over the top 200 m at
both sites. In addition, at the southern site the mooring has an in
situ natural fluorometer at 30-40 m depth and a pCO2 sensor at 60
m.
|
Work will
continue to at least 2008 |

French
Malvinas/Falklands current mooring array.
|
An array of
current meter moorings has been located in the region of the Malvinas
Current at 41°S since 1999, to evaluate the water mass transport
associated with the Malvinas Current and the exchange of subantarctic
waters between the Antarctic and Atlantic
Oceans.
|
An array of 3
current meter moorings was deployed in Dec. 2002 under JASON track
26. This array should be recovered later this year. A Yoyo profiler with CTD and nitrate analyser will also
be deployed soon.

Antarctic
Sea-Ice Thickness Project (AnSITP) |
Since the start
of the project, 53 moorings with upward-looking sonars have
been deployed. The present 6 AWI ULS-moorings are located along the
Greenwich Meridian in the Weddell Sea. These records exist since 1996
and will be continued at least until 2004.

established on the Filchner sill, where the Filchner Depression
intersects the continental shelf brake. |
