2014 Planned Field Operations


In 2014, we plan to have the High Frequency Radar (HFR) sites in Point Lay and Wainwright operational in June, and to have the sites at Point Barrow and Cape Simpson operational in July. The Point Barrow site will use the remote power module (RPM) that was was originally fabricated in 2010 with funding from the Center for Island, Maritime, and Extreme Environment Security (CIMES). The Cape Simpson site, east of Point Barrow, will be powered by an RPM that was funded by the State of Alaska Coastal Impact Assistance Program (CIAP). All sites will be reporting hourly real-time surface current velocities approximately 100 miles offshore until sea ice ceases data returns.

High-Resolution Shipboard Survey

In September, 2014, there was a cruise aboard the Norseman II to perform a high-resolution shipboard survey. During the cruise, our Sea Sciences Acrobat towed research platform measured profiles of temperature, salinity, pressure, chlorophyll, dissolved organic matter, and particle concentrations. Additional vessel instrumentation includes a vessel mounted Acoustic Doppler Current Profiler (ADCP) and a Thermosalinograph (TSG).

We had planned to deploy one Webb Slocum glider with a long-term lithium battery in July, 2014, but there was too much ice in the area. Instead, it will be deployed with the other two gliders during the September cruise. Gliders will be piloted from UAF, and will perform independent surveys of the shelf. All gliders will record temperature, salinity, and optics data and they all will be recovered in September.

Met-Ocean Buoys

The UAF meteorological buoy that is funded under this project will be deployed again in 2014 by Evans Hamilton RPS in late July or early August offshore of Point Lay. Measured properties will include wind speed, wind direction, wind gust, air temperature, water temperature, relative humidity, barometric pressure, solar radiation, pitch, roll, and battery voltage. There will also be several industry sponsored meteorological buoys deployed in the Chukchi Sea. All buoys will be recovered when ships leave the area for the season in early to mid-October.

Current meter moorings

The current meter mooring nearest to Wainwright, BC2, will be recovered and re-deployed from the Norseman II in September. These instruments store data internally, so the data will downloaded after the moorings are recovered.
