Barrow Alaska
Observatory Operations: BRW
Barrow Observatory, established in 1973, is located near sea level 8 km east of Barrow, Alaska at 71.32 degrees north. This facility is manned year around by 2 engineers/scientists who often commute to work in winter on snow machines. Due to its unique location, dedicated and highly trained staff, excellent power and communications infrastructure, the Barrow Observatory is host to numerous cooperative research projects from around the world. ...

Barrow, Alaska
The Barrow station began measuring aerosol radiative properties in 1976. Since 1988, simultaneous measurements of light absorption and light scattering (as a function of wavelength) have been made. A major upgrade of the aerosol sampling system was completed on October 5, 1997. The new system was funded by the Atmospheric Radiation Measurement program of the U.S. Department of Energy ( DOE/ARM ). The new system provides aerosol measurements that are quantitatively comparable to measurements at other NOAA/CMDL and DOE/ARM sites. In addition to improved instrumentation, the new system measures aerosol properties in two particle size ranges at a controlled relative humidity. The old and new systems were operated in parallel for one year to evaluate any potential biases introduced in to the long time series of aerosol measurements at Barrow. The new system was referred to as North Slope of Alaska (NSA) during the overlap period. A comparison of the measurements shows good agreement betwe ... [Read More]
ARM - Sites: NSA Barrow Facility
The Barrow facility has a trailer and platforms to support the instrumentation and data system. Significantly, an extended range AERI (ER-AERI) is operating at Barrow. The ER-AERI was built specifically for the high latitudes where low water vapor concentrations are common. ARM also operates many of the same instruments, including a 35-GHz cloud radar, that are located at its warmer sites. However, many of these instruments have been hardened to withstand temperatures that drop below -40 C/F. Barrow Instruments ... [Read More]

11:30 pm and still at work under the midnight sun! Jim Liljegren poses next to a microwave radiometer that he and Kevin Widener had just installed at ARM's Cloud and Radiation Testbed site in Barrow, Alaska. The microwave radiometer was the first instrument to be installed at the Barrow site. It will provide continuous measurements of vertically-integrated water vapor and cloud liquid water for scientists engaged in global change research at PNNL and world-wide.

A Native Whaler's View
My name is Burton "Atqaan" Rexford. I was born in 1930 at Pt. Barrow "Nuvuk", Alaska and now reside in Barrow, Alaska. I am a whaling captain and the Chairman of the Alaska Eskimo Whaling Commission (AEWC), which is made up of ten subsistence villages: Gambell, Little Diomede, Barrow, Nuiqsut and Kaktovik. ... Eskimo hunters at Barrow, Nuiqsut and Kaktovik, Alaska are concerned that cumulative effects of offshore activities, especially seismic exploration, may have displaced fall migrating bowhead whales thereby affecting their subsistence hunt. In March of 1997, MMS sponsored a workshop at llisagvik College in Barrow, Alaska, to discuss whaling and offshore oil and gas activities. Whaling Captains and crew from Barrow and the villages of Nuiqsut and Kaktovik, along with experts from the scientific community, regulatory agencies and industry attended the workshop. ...

BARROW SNOWMELT DATE
). Both sites are within the Kuparuk River Watershed located southeast of Barrow. Barter Island BTI (70.1°N, 143.6°W; elev. 15 m) was another NWS station where, until 1987, melt dates were determined from snow depth data. The series labeled satellite SAT was derived from visible satellite images of a strip of tundra about 150 km south of Barrow, Alaska [Foster et al., 1992]. The upper two curves in Figure 3a are proxy records. Cooper Island CPI (71.7°N, 155.7°W; elev. 3 m) is a time series of dates when a species of Arctic bird, the Black Guillemot, first lays an egg. Each spring Guillemots nest on the island but only after the snow melts and they have access to nest cavities do they breed, producing their first clutch of eggs about two weeks later. Isaktoak ISK is a time series of dates when ice has melted completely off of the Isaktoak Lagoon, which is located in the village of Barrow. These proxy records are correlated with the BRW time series suggesting that snowmel ... [Read More]

With the impact of global warming, Barrow AK has experienced warmertemperatures than Kotzebue AK which is situated in atransitional climate zone, where as Barrow AK is classified as anarctic climate zone. [1] ... "In ecologically less favorable districts, local families mightinclude a dozen or so members whereas in highly productive areas, local family size could reach as high as 50 or more. Major population centers such as Point Hope and Point Barrow, located along sea mammal migration routes, contained several large local families clustered in distinct locations or neighborhoods, each set linked together by various affinal and consanguineal kinship ties."

Antarctic UV Spectroradiometer Monitoring Program: Contrasts in UV Irradiance at the South Pole and Barrow, Alaska
Barrow, Alaska, contrasts with the South Pole in that it is located where a significant change in surface albedo occurs due to both the springtime snowmelt [ Dutton and Endres , 1991] and changes in sea-ice coverage. Also, Barrow experiences significant changes in incident irradiance due to Arctic storms. The contrast in irradiances between Barrow and the South Pole is seen in Figure 1b, which depicts the integrated noontime irradiances over the UV-A spectrum (320-400 nm) from January 1993 through December 1995. ...
