| Zusammenfassung |
| The Ross Ice Shelf Ocean Cavity, at a volume of around 125,000 km3, is one of the
largest and least explored ocean regions of the Antarctic coastal margin. Ice Shelf
Water (ISW) flowing out from the cavity on the Coriolis-favoured western side of
the cavity flows either side of Ross Island. To the east of the island is the zone
most often associated with the Ross Sea Polynya and typically thought of as the
dominant exit pathway. Haskell Strait is the largely ice-covered, and lesser understood,
connection between the two water bodies to the south of Ross Island. In particular, this
flow path, the so called Victoria Land Coastal Current, interacts with numerous
smaller shelves and floating glaciers. Here we consider available data and simulations
to seek answers to (i) Is there exchange flow within the Strait? (ii) What are the
implications for sea ice once ISW passes through the Strait and finally (iii) is ISW
flow through the Strait of any significance compared to other exit pathways? We
synthesize data from various campaigns over the last decade, along with ROMS cavity
circulation modelling, and project out to contributions from up-coming initiatives. |
