IEEE Transactions on Geoscience & Remote Sensing:
Deep ocean convection, the process by which the deep waters of the world's oceans are created and renewed, plays a keg role in the global thermohaline circulation and hence the world's heat balance. The process of deep ocean convection involves a vigorous overturning of the ocean mater column down to depths of 2000-3000 m in an area probably not larger than 50 km in diameter. This paper details the results of a theoretical study to identify remotely sensible surface signatures for deep ocean convection. Due to the all-weather capability, efforts have focused on the microwave part of the spectrum, particularly the high resolution imaging capability of synthetic aperture radar (SAR). The goal of this research is to use the SAR surface signature or "fingerprint" to identify and characterize areas of convection in the open ocean. This information is then used to improve model parameterizations for deep convection used in general circulation models.
