Beluga Whales Cook Inlet Alaska Tidal and Environmental Hydrodynamic Inundation Model
2015/7/22
The population of beluga whales in Cook Inlet, Alaska, is in decline, and since 2000 these whales have been under consideration for designation as "endangered" under the Endangered Species Act (and we...
A Child's View of Circulation in Prince William Sound, Alaska?
Prince William Sound Circulation
2015/7/20
An oceanographic field exercise was conducted in central Prince William Sound, Alaska, in mid summer 2004 to evaluate the capability of the Prince William Sound Observing System to forecast the trajec...
Recent lake ice-out phenology within and among lake districts of Alaska, U.S.A.
lake districts of Alaska
2014/4/2
The timing of ice-out in high latitudes is a fundamental threshold for lake ecosystems and an indicator of
climate change. In lake-rich regions, the loss of ice cover also plays a key role in landsca...

CO2 the photosynthetic physiology phytoplankton the Gulf of Alaska
2014/4/16
In the high-nutrient, low-chlorophyll waters of the Gulf of Alaska, microcosm manipulation experiments were used to assess the effect of CO2 on growth and primary production under iron-limited and iro...
Dark production of hydrogen peroxide in the Gulf of Alaska

On the Ocean Temperature Distribution in the Gulf of Alaska, 1974–1975
Ocean Temperature Distribution Gulf of Alaska
2009/3/7
Infrared data gathered by the NOAA 3 and 4 satellites have made it possible to construct a detailed synoptic view of sea surface temperatures in the northern Gulf of Alaska. These satellite data are c...
Observed Surface Winds at Middleton Island, Gulf of Alaska and Their Influence on the Ocean Circulation
Observed Surface Winds Middleton Island Ocean Circulation
2009/2/16
Winds observed at an island in the Gulf of Alaska display a large annual signal with maximum easterlies in winter and weak easterlies in summer. For the northern Gulf of Alaska, the monthly mean Ekman...
Coastal Flow in the Northern Gulf of Alaska as Observed by Dynamic Topography and Satellite-Tracked Drogued Drift Buoys
Coastal Flow Dynamic Topography Satellite-Tracked Drogued Drift Buoys
2009/2/13
Drifting buoys and dynamic topography over the continental shelf in the northern Gulf of Alaska are used to describe the coastal circulation and flow in the offshelf Alaska Current. One permanent anti...
On the Effect of Precipitation and Runoff on Coastal Circulation in the Gulf of Alaska
Precipitation Runoff Coastal Circulation
2009/2/13
Surface waters in the Gulf of Alaska undergo a net dilution throughout most of the. year since the regional precipitation exceeds evaporation. Recent hydrographic data give evidence that seasonal dyna...
On Lateral Water Mass Interaction—A Case Study, Bristol Bay, Alaska
Lateral Water Mass Interaction Bristol Bay Alaska
2009/2/13
Salinity-temperature-depth data obtained on several spring and summer cruises during 1976 and 1977 from outer Bristol Bay in the southeast Bering Sea indicate the existence of a zone, between two well...
Variability of Current and Bottom Pressure Across the Continental Shelf in the Northeast Gulf of Alaska
Current Continental Shelf Bottom Pressure Northeast Gulf of Alaska
2009/2/11
The low-frequency (<0.25 cph) velocity and bottom pressure variability were studied in the northeast Gulf of Alaska from March to August 1976. Measurements of velocity in 100, 185 and 250 m of water s...
