2013 Planned Field Operations
In 2013, High Frequency Radar (HFR) sites in Point Lay, Wainwright, and
Barrow will once again be operational beginning in late June/early
July. Last season's Barrow site will be moved from grid power to an
existing remote power module (RPM) at Point Barrow that utilizes solar
and wind power. The RPM was originally fabricated with Center for
Island, Maritime, and Extreme Environment Security (CIMES
) funding in 2010. Additionally, this year a
fourth site will be added at Cape Simpson (east of Point Barrow) in
August. A newly fabricated RPM will power the radar equipment at
Cape Simpson and is 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
- Update: The HFR season for 2013 is over, and the sites are off for the winter.
High-Resolution Shipboard Survey
In 2013, the high-resolution shipboard survey utilizing the Sea Sciences
platform measuring temperature, salinity, pressure, chlorophyll,
dissolved organic matter, and particle concentrations will collect a
second year of data in the northeast Chukchi from the Norseman II
in September. Last year more than 4,000 CTD profiles were collected
over 1,200 nm. Upgrades for the survey this year include a vessel
- Two Pacifc Gyre SVP drifters remained on the Beaufort Shelf, after having been frozen in the sea ice all winter. They have since beached.
- Twenty Pacifc Gyre Microstar surface drifters have deployed around of Hanna Shoal in September from the Norseman II.
- The North Slope Borough Department of Wildlife Management (NSBW) deployed 5 MetOcean iSPHERE drifters (which have all since beached) and 52 Pacifc Gyre Microstar drifters.
- Update: 5 of the drifters deployed in 2013 are currently operational, and all are stuck in ice.
View 2013 Data
In 2013, two Webb Slocum Gliders
and one Exocetus Coastal Glider
will be deployed in the northeast Chukchi. One Webb
Slocum Glider will utilize a long-term Lithium battery and be deployed
from the Westward Wind in late July/early August. The second Webb
Slocum Glider and the Exocetus Coastal Glider will be deployed in
September from the Norseman II. All gliders will record temperature,
salinity, and optics data and be recovered by the Norseman II in
Funded under this project, the UAF meteorological buoy will
be deployed once again in 2013 by Evans Hamilton RPS
in late July/
Early August offshore of Point Lay. Measured properties 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 three industry sponsored
meteorological buoys in the regions of Burger, Klondike, and Hanna
Shoal. All buoys were recovered when ships left 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, as will
Weingartner's COMIDA project Hanna Shoal moorings. Two additional
Hanna Shoal moorings will be deployed in conjunction with this project
by Robert Pickart, WHOI, from the USCGC Healy. Dr. Pickart will also
deploy moorings in the western Beaufort Sea.
These instruments store data internally, so the data will downloaded after the moorings are recovered.
- Update 10/8/2013: Current meters have been recovered successfully. 7 have been deployed
