Fields of interest
Tropical and extratropical air-sea interaction observed from heavily instrumented surface moorings and Saildrone (an autonomous sailing vessel !!). Particular interests include frontal dynamics, large-scale ocean dynamics, upper ocean processes, hydrological cycle, coupled feedback processes, physical processes of the carbon cycle, and model assessment studies using reference station observations.

Description of scientific projects
There is a growing database of observations in the tropics and at higher latitudes that can be used to investigate air-sea interaction and upper ocean processes. I am lead PI on a Tropical Pacific Observing System (TPOS)-2020 project that will send 2 saildrone ( to the tropics to test this new innovative platform, a remotely-controlled sailboat, and its ability to make climate quality surface meteorological, oceanic, and biogeochemical measurements. The first mission will be to the NASA sponsored SPURS-2 study site. As a postdoc, you would be participating in SPURS-2 ( as well as TPOS-2020 (, using cutting edge technology. I also lead the NOAA PMEL Ocean Climate Stations program that maintains surface reference station moorings in key regions of the climate system ( At present we have two moorings in the North Pacific – the Kuroshio Extension Observatory (KEO), which is in the western boundary current region where the ocean warms the atmosphere and subtropical mode water is formed; and Station Papa in the Gulf of Alaska, which is a region where the effects of ocean acidification are expected to manifest. These moorings were both initiated during process studies and thus are part of a larger data set that place these observations within the mesoscale and large-scale context. Their data can be used in a variety of analyses investigating processes on diurnal-interannual and longer time scales.
