Physical Oceanography

The projects listed below are examples of how CFOS's physical oceanographers:

  • Observe and monitor Alaskan oceanographic conditions;
  • Provide data and model results that would be critical to oceanic disaster response efforts and ocean climate policy;
  • Develop new technologies tailored to conditions in Alaskan arctic and sub-arctic waters;
  • Collect supporting information needed for an ecosystem-based approach to resource management.
 

A Real-Time Sensor System for Detecting Freeze-up on Arctic Shelves 

In Fall 2015, a moored array measured temperature in the Chukchi Sea and reported data in real-time via satellite as sea ice was forming.

 

 Alaska Region Digital Elevation Model

We developed a bathymetric dataset that incorporates data sources from Alaskan and Russian waters to improve coverage there.

 

 Arctic Ecosystem Integrated Survey

A comprehensive assessment of the northeastern Bering Sea and Chukchi Sea (NEBS/CS) ecosystems.

 

 Arctic ice-ocean modeling

Models of high latitude areas such as the Beaufort, Bering, and Chukchi Seas are being developed for oil spill risk analyses, oil spill response planning efforts, climate studies, and scientific studies.

 

 Arctic Marine Biodiversity Observing Network (AMBON)

A demonstration project of a national network to monitor biodiversity in the Arctic from microbes to whales.

 

 Arctic Tracer Release Experiment (ARCTREX): Applications for Mapping Spilled Oil in Arctic Waters

Data collected during a dye release study was displayed in real-time by NOAA's Environmental Response Management Application.

 

 Chukchi Beaufort Circulation Study

Field studies using drifters, gliders (AUVs), high-frequency radars (HFRs), meteorological buoys, a high-resolution cruise surveys, and year-round moorings.

Chukchi Sea Environmental Studies Program

A multi-year, multi-discipline marine science research program in the northeastern Chukchi Sea.

 

 Coastal Community Ocean Observers (C2O2): A network of community-driven coastal ocean observations

Alaskan coastal communities are collecting oceanographic data in collaboration with researchers at UAF.

 

 Cook Inlet Circulation Studies

A field study of the circulation of Kachemak Bay using drifters.

 

 End-to-end fish model

Modeling multi-decadal cycles of sardines and anchovies using physics, nutrient-phytoplankton-zooplankton, and fisheries.

A Chukchi Sea mooring records physical, nutrient and carbonate chemistry, particulate, phytoplankton, zooplankton, and fisheries data.

   Port Valdez Environmental Studies Program
   Resilience and adaptive capacity of arctic marine systems under a changing climate (RACArctic)
 

 Satellite tracked drifters

We have released hundreds of drifters in the Bering and Chukchi Seas since 2002 with the help of local residents.

 

 Seasonal Ice Zone Observing Network (SIZONET)

SIZONet is an interdisciplinary project that implements an integrated program for observing seasonal ice in the context of a changing Arctic.

 

 Surface Currents

Measuring surface currents in the Northeastern Chukchi and Western Beaufort Seas utilizing shore-based High Frequency Radar (HFR) systems.
