The Sea Ice Index provides a quick look at sea ice changes in spatial and historical context and gives a consistent, up-to-date source of sea ice extent and sea ice concentration values and images. The NSIDC Near-Real-Time DMSP SSM/I Daily Polar Gridded Sea Ice Concentrations and the Sea Ice Concentrations from Nimbus-7 SSMR and DMSP SSM/I Passive Microwave Data data sets are used to generate the monthly records of sea ice extent and sea ice concentration for the Arctic and Antarctica from satellite passive microwave data. Data files tabulate monthly mean extent and area, in millions of square kilometers, by year for a given month. Plots of monthly sea ice extent anomalies with trend lines and significance intervals...
This dataset provides information on fish species composition and their diet information for 16 lakes and 16 ponds at two locations on the central Arctic Coastal Plain, Alaska. In one table, we provide the presence of fish species and the total species count for each lake or pond sampled. This table also includes metrics of surface water connectivity to the stream network. In a second table, stomach content information is provided for fish collected during summer sampling periods (late June to mid-August) over three years (2011–2013). The third table includes stable carbon isotope and stable nitrogen isotope signature data for fish species and snails (the baseline organism) from 16 water bodies at one study location...
Climate change is already affecting ecosystems, and will likely trigger significant and permanent changes in both ecological and human communities. Such transformations are already occurring in the Arctic region of Alaska, where temperatures are warming at twice the global average and causing some ecosystems to transition to new states. Arctic warming has led to coastal erosion that has forced human communities to relocate and a loss of sea ice that has forced marine mammals, such as polar bears and walrus, to adapt to a more terrestrial mode of living. Meanwhile, in the Great Plains of the U.S., past interactions between land and water use during the Dust Bowl and recent high rates of depletion of the Ogallala...

Snow conditions are extremely important to a wide range of hydrologic and ecosystem components and processes, including those related to surface energy and moisture stores and fluxes, vegetation, mammals, birds, and fish. The required snow datasets currently do not exist at the required spatial and temporal resolutions needed by end users such as scientists, land managers, and policy makers.

The digitally compiled map includes geology, oil and gas field centerpoints, and geologic provinces of the Arctic (North Pole area encircled by 640 N Latitude). The GIS data sets were designed originally in ESRI's ARC/INFO ver. 8.0.1 and were published as part of a series of interim CD-ROM products of the U.S. Geological Survey's World Energy Project (WEP). The goal of the WEP is to assess the undiscovered, technically recoverable oil and gas resources of the world. Results of this assessment were reported in the year 2000 (see USGS DDS-60; http://pubs.usgs.gov/dds/dds-060/).

The dataset consists of geochemical and isotopic data from fine-grained sediments and glendonite crystals collected at Carter Creek on the North Slope of Alaska. Total Organic Carbon (TOC) values in the measured section were found to range between 0.5 and 3.5%, with a shift towards lower values in the uppermost 5 m of the section. Stable isotopes (13C) in organic matter were relatively stable throughout the section, ranging between -25.5 and -26, with a slight 0.3 per mil positive shift within this range approximately 57 m from the base of the section. Glendonites themselves were analyzed for δ13Ccarb and δ18Ocarb, with δ18O values relatively consistent between -0.22 and +1.28, and a much wider range of δ13C values...
Typed information accompanying photograph: Print only. Similar to A-1, but slightly different view. Lamont work trailer at early light, probably mid February, 1969. There were several weeks with dawn and dusk, but no daylight. Note: T-3 Photographs - Roll A - Color slides - February - March 1969. These photos were taken during February and March of 1969 and developed into Ektachrome slides in May of 1969. Some have deteroriated. When the slides were new some of them were printed as color prints. Some prints don't have matching slides. A few slides were copied as Kodacolor slides some time during the 1970s and there are some duplicate slides. The Kodacolor slides have not deteriorated. Some images are missing....

Typed information accompanying negative: The second load: This drop was also on target. Note: T-3 Photographs - Roll F B&W negatives - June paradrop, 1969. There were three paradrops during the summer of 1969 performed by Navy C-130 planes from Elmendorf Air Force Base in Fairbanks, Alaska. These are described in this website, http://www.firebirds.org/menu2/t3/t3_p02.htm On the receiving end of the paradrops on T-3, these days were the high points of the summer season. This roll documents the first paradrop, which occurred in late June on a cloudy day. The loads were delivered on target to the camp runway without mishap. The second paradrop was similar, one month later. The day of the third paradrop was windy...

Typed information accompanying slide: Telephone lines to the GM camp in the twilight. The colors at dusk were lovely. Similar to D-9. Link to this photograph is listed below in Web Links. Note: T-3 Color slides - Roll D - Color slides September 1969. These photos were developed in late 1969 after I returned from T-3 and made into Kodacolor slides. Photos by Dave Scoboria.
Typed information accompanying negatives: Graham Law was one of the two employees on T-3 working for Lamont in the summer of 1969. I believe that he was a student at Columiba University. We flew to T-3 on one of the NARL DC-3s on June 1, 1969. We had never met before, but in an odd coincidence we had once dated sisters when we were in high school. Note: T-3 Photographs - Roll F B&W negatives - June paradrop, 1969.

USGS hydrohut with pressure ridges in the distance. T-3 (Fletcher's) Ice Island, Arctic Ocean. 1969.
Typed information accompanying photograph: Slide and print: USGS hydrohut with pressure ridges in the distance. Taken from the top of the Lamont hydrohut tower. Similar to B-16, but slightly different view. Note: T-3 Photographs - Roll B - Color slides April 1969. These photos were developed into Ektachrome slides in May of 1969. Some have deteriorated. Some were printed as color prints and these may be in better condition than the slides. A few slides were copied into Kodacolor slides. Some images are missing. Photos by Dave Scoboria.
