Educational Opportunities

Graduate students in the Ocean Physics Department take their coursework through an academic department at the UW, while pursuing research projects with a faculty advisor in OPD. Students are offered the opportunity to experience the entire life cycle of sea-going research projects, including experiment planning, participation in research cruises, data processing, scientific analysis and the presentation of results at national and international meetings.  More >>
Current Students >>

What We Do

OPD investigators pursue research focused primarily on small-scale and meso-scale oceanographic processes, design and build unique instruments to facilitate these studies, and educate undergraduate and graduate students through instruction and employment.

Basic and Applied Research Push Seaglider's Capabilities

Seaglider offers depth, versatility, and persistence at an operating cost far less than an ocean research vessel. People should like them because they're really cool, but they do like them because they're comparatively inexpensive. In May 2013, UW's Center for Commercialization licensed the manufacture of Seagliders to Kongsberg Underwater Technology, Inc., granting them sole rights to produce, market, and continue the development of Seaglider technology.  More >>

Marginal Ice Zone Program

An integrated program of observations and numerical simulations will focus on understanding ice–ocean–atmosphere dynamics in and around the MIZ, with particular emphasis on quantifying changes associated with decreasing ice cover. The MIZ measurement program will employ a novel mix of autonomous technologies (ice-based instrumentation, floats, drifters, and gliders) to characterize the processes that govern Beaufort Sea MIZ evolution from initial breakup and MIZ formation though the course of the summertime sea ice retreat.  More >>

Deep-Sea Rescue of Valuable Research Instruments

The subsurface mooring component of the Northwest Enhanced Moored Observatory (NEMO) had to be rescued by a ROV piloted by APL-UW engineers. Extensive crevice corrosion from a longer-than-expected deployment was behind the acoustic release failures. More >>

Puget Sound's rich waters supplied by deep, turbulent canyon

UW News and Information,

14 Apr 2014

The headwaters for Puget Sound%u2019s famously rich waters lie far below the surface, in a submarine canyon that draws nutrient-rich water up from the deep ocean. New measurements may explain how the Pacific Northwest%u2019s inland waters are able to support so many shellfish, salmon runs and even the occasional pod of whales.

Scientists say a deep canyon feeds Puget Sound

King5 News (Seattle),

14 Apr 2014

University of Washington researchers said they are astounded by the volume of deep sea water that is flowing through an underwater canyon at the mouth of the Strait of Juan de Fuca.
