The uncorrected (for sea level) ULS draft values are included in the point data set but are not included in the summary file. The Expedition is funded by the Netherlands … instrument depth; sea ice draft. By continuing to browse this site you agree to us using cookies as described in About Cookies..

We have removed any draft greater tham 30 m in computing the draft statistics. Location of the shelf slope front and degree of baroclinicity in the Weddell Gyre [Meredith et al., 2008; Jullion et al., 2010] place further constraints on the export of dense water.
Marking the edge of the continent, the break between shelf and continental slope lies at a depth of about 1,600 feet (500 metres). The south-western and southern borders of the sea are formed by the Larsen and the Filchner-Ronne Ice Shelves which produce the huge tabular icebergs that are so abundant in the Weddell Sea. In addition, the Expedition has measured sea ice freeboard and snow depth in the Weddell Sea, which will help better understand Antarctic sea ice thickness and its implications for climate change and global ocean circulation. The uncorrected (for sea level) ULS draft values are included in the point data set but are not included in the summary file.

The biggest physiological challenges in adapting to pressure are probably faced by those animals that must routinely travel from the surface to great depth. We have removed any draft greater tham 30 m in computing the draft statistics. Six adult Weddell seals were equipped with Argos PTTs, so called Conductivity Temperature Depth-combined data loggers, in austral summer 2014 in the Filchner Outflow System. Some sea creatures exploit great depths.
Built in 2007, by Sea Boats Incorporated of Fall River, Massachusetts (hull #7) as the Scott C. for Sea Boats Incorporated of Portsmouth, Rhode Island. Diving: Weddell seals are impressive divers, they can reach 600m in depth and spend as long as 82 minutes, the longest dives are undertaken when swimming under ice searching for new breathing holes. Where she was renamed as the Weddell Sea. First discovered by James Weddell in 1823, the Weddell Sea is home to vast tabular icebergs, pack ice, a barren landscape, grand vistas and some of Antarctica’s greatest penguin rookeries.
Weddell Sea-derived Antarctic Bottom Water (AABW) is one of the most important deep water masses in the Southern Hemisphere occupying large portions of … Differences between snow depth estimates from a repeat survey of one Weddell Sea track separated by 12 days, without accounting for variability due to ice motion, is −0.7 ± 13.6 cm. About Cookies, including instructions on how to turn off cookies if you wish to do so. Weddell Plain) is an undersea abyssal plain named in association with the Weddell Sea. Average snow depth is thicker in coastal northwestern Weddell and thins toward Cape Norvegia, a decrease of >30 cm. Number of samples. The Antarctic Bottom Water of the Weddell Sea usually ranges from -0,8 to 0 degrees Celsius (31.8 to 32 degrees Fahrenheit), but surface temperatures are generally below freezing. One mooring, AWI206, has what appear to be a lot of ice bergs (or bad data) with drafts up to 100m. A number of sampling sites have been regularly revisited between annual ice formation and breakup each year to obtain a continuous record of snow depth, freeboard, sea-ice- and sub-ice platelet layer thickness across the bay. The bay is located on the north-eastern edge of Ekström Ice Shelf in the eastern Weddell Sea, close to the German wintering station Neumayer Station III. Those data loggers record data on geographic position, dive behaviour and hydrography at the same time (temperature and salinity, the latter from the conductivity). seasonality in surface conditions such as sea ice formation and brine rejection [Drinkwater et al., 1995].
In 2011, the tug was acquired by the K-Sea Transportation Partnership of East Brunswick, New Jersey. Conservation status: Least concern. Weddell Sea Covering an area of approximately 2.8 million square kilometres between the South Shetland Islands and the continent of Antarctica, the Weddell Sea is among the harshest and most treacherous environments in the world.
