High salinity shelf water
WebApr 11, 2024 · Coastal polynyas in the Ross Sea are important source regions of high salinity shelf water (HSSW) – the precursor of Antarctic Bottom Water that supplies the lower limb of the thermohaline circulation. Here, the response of sea ice production and HSSW formation to synoptic- and meso-scale cyclones was investigated for the Ross Ice … WebThe fresh water from rivers has salinity levels of 0.5 ppt or less. Within the estuary, salinity levels are referred to as oligohaline (0.5-5.0 ppt), mesohaline (5.0-18.0 ppt), or polyhaline …

WebWeddell Sea Bottom Water is a subset of Antarctic Bottom Water that is at a temperature of -0.7 °C or colder. It consists of a higher salinity branch and a lower salinity branch. It … WebHigh Salinity Shelf Water (HSSW) is a major component of Antarctic Bottom Water (AABW), a water mass that fills the lowest kilometer of the world’s oceans and drives global thermohaline circulation.
WebThe water column is destratified to ~350-m depth by the end of September, and the mixed-layer salinity reaches ~34.5 g kg −1, as observed. If the contribution from meteoric water is not taken into account, convection extends to the seafloor and the mixed-layer salinity (~34.6 g kg −1) is higher than observed. WebMay 27, 2024 · 3. The salinity of water increases as the water moves from the inland area to the ocean. This is because the ocean has high salinity. Salinity is the amount or …

Salinity and potential … WebThe formation of High-Salinity Shelf Water (HSSW), which is the major source of Antarctic bottom water (AABW), has been observed in Terra Nova Bay (TNB) in Antarctica. We believe that a description of the spatio-temporal variation of salinity in TNB would help understand the production of HSSW in the region.
WebWater Salinity. Cold, high-salinity water of the west-wind drift of the Southern Ocean current system lies above the slope year-round, and when the Leeuwin Current flow is relaxed in austral summer this water mass intrudes over the shelf break and may flood onto the continental shelf.
