Two new ocean tide models for the Ross Sea including the ocean cavity under the Ross Ice Shelf, are described. The optimum model for predicting ice shelf surface height variability is based on assimilation of gravimetry-derived tidal constituents from the Ross Ice Shelf. Synthetic aperture radar interferograms provide an independent test of model performance. The standard deviation of tide heig...

The interaction between the atmosphere and ocean is of fundamental importance for understanding the dynamics and thermodynamics of the atmosphere and the ocean. Understanding of the upper ocean response to intense wind forcing has been limited by the paucity of direct observations. A circular region within a radius of 400 km of Bermuda has been struck by 188 tropical storms or hurricanes from 1...

Warming ocean currents are considered to be a contributing factor to the retreat of marine-terminating glaciers worldwide, but direct observations near the ice–ocean interface are challenging. We use radar intensity imagery and an iceberg tracking algorithm to produce half-hourly current maps within an imaged portion of Jökulsárlón, a proglacial lagoon in southeastern Iceland. Over our 43.5-h o...

The influence of oceanic heat transport on the sensitivity of climate to an increase of the atmospheric CO 2 concentration is studied by comparing the CO2-induced changes of two mathematical models. The first model is a general circulation model of the coupled ocean-atmosphere system which includes ocean currents. In the second model the oceanic component of the first model is replaced by a sim...
