| Title: | Observations of thermohaline convection adjacent to Brunt Ice Shelf / Ilker Fer, Keith Makinson, Keith W. Nicholls. |
| Author(s): | Fer, Ilker. Makinson, Keith. Nicholls, Keith W. |
| Date: | 2012. |
| In: | Journal of Physical Oceanography. (2012.), Vol. 42(3) (2012) |
| Abstract: | Presents observations of ocean microstructure and horizontal currents adjacent to Brunt Ice Shelf in south-eastern Weddell Sea in February 2009, where periods of in situ supercooled water extending as deep as 65 m were associated with ice nucleation and frazil formation at depth. Ascending ice crystals due to convection lead to increased dissipation rates. Main outflow of potentially supercooled water from deep beneath ice shelf is suggested to be in deep channel northeast of measurement site. Because this water is advected southward along front, it becomes in situ supercooled, leading to suspended ice formation, thermohaline convection, and enhanced dissipation. |
