Abstract: bservations were made of ocean microstructure and horizontal currents adjacent to Brunt Ice Shelf in the southeastern Weddell Sea. Periods of in situ supercooled water extending as deep as 65 m were associated with ice ...

Abstract: nder ice measurements by seals carrying a miniaturized conductivity?temperature?depth (CTD) instrument fill an important gap in existing observations. Here the authors present data from an instrumented Weddell seal that ...

Abstract: iffusive convection?favorable thermohaline staircases are observed directly beneath George VI Ice Shelf, Antarctica. A thermohaline staircase is one of the most pronounced manifestations of double-diffusive convection. ...

Abstract: Parameterizations of turbulent transfer through the oceanic boundary layer beneath an ice shelf are tested using direct measurements of basal ablation. Observations were made in the southwestern part of Ronne Ice Shelf, ...

Abstract: he exchange between the open ocean and sub?ice shelf cavities is important to both water mass transformations and ice shelf melting. Here, the authors use a high-resolution (500 m) numerical model to investigate to which ...

Abstract: ABSTRACTOpen-ocean polynyas in the Weddell Sea of Antarctica are the product of deep convection, which transports Warm Deep Water (WDW) to the surface and melts sea ice or prevents its formation. These polynyas occur only ...
