Tides in the Weddell Sea

Modelling tides in the southern Weddell Sea: updated model with new bathymetry from ROPEX

A significant fraction of the total oceanic kinetic energy in the southern and western Weddell Sea is supplied by tidal currents [Robertson et al., 1998: denoted “RPE-98”]. The region of strong tides includes the ocean cavity under the Filchner-Ronne Ice Shelves (FRIS), and the adjacent broad southern continental shelf and upper slope. The spatial distribution of tidal energy was estimated usin...

Internal tides and baroclinicity in the southern Weddell Sea 1. Model description

Near the continental shelf break in the southern Weddell Sea, Warm Deep Water and Western Shelf Water meet. Mixing mechanisms, such as internal tides, have the potential to mix these water masses and form Antarctic Bottom Water. A modified version of the Princeton Ocean Model was utilized to investigate the internal tidal fields generated by the interaction of the M2 barotropic tide with topogr...

Internal Tides and Baroclinicity in the Southern Weddell Sea. Part I: Model Description and Comparison of Model Results to Observations

In the southern Weddell Sea, several water masses with the capability to form Antarctic Bottom Water (AABW) meet near the continental shelf break. The internal tidal field over the continental shelf break here is of interest due to its potential to mix these waters and form AABW. A modified version of the Princeton Ocean Model (POM) was utilized to investigate the internal tidal fields generate...
