Typed information accompanying negative: USGS hydrohut and an unidentified hydrohut and trailer, with tangle of electric lines, taken from the USGS trailer, late August/early September. Note: T-3 Photographs - Roll I B&W negatives – August-September 1969 This roll shows activities during August and September 1969 on T-3. The summer season had now lasted two months. The weather grew cold. Photos by Dave Scoboria.

Typed information accompanying slide: A wide shallow lake. At the edge of the lake there is fresh water on top of ice island, water a foot or so deep. One of the camp members walked far out on the lake. June 1969. Similar to C-33 and C-34. Links to these images listed in Web Links below. Note: T-3 Color slides - Roll C - Color slides June 1969. These photos were taken between June 6, 1969 and June 27, 1969 and developed in late 1969 into Kodacolor slides after returning from T-3. One slide has deteriorated. Photos by Dave Scoboria, except for C-6.

This dataset consists of long-term (~63 years) shoreline change rates for the north coast of Alaska between the U.S. Canadian Border and the Hulahula River. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.3, an ArcGIS extension developed by the U.S. Geological Survey. Long-term rates of shoreline change were calculated using a linear regression rate-of-change method based on available shoreline data between 1947 and 2010. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate long-term rates.

This dataset includes a reference baseline used by the Digital Shoreline Analysis System (DSAS) to calculate rate-of-change statistics for the sheltered north coast of Alaska coastal region between the Hulahula River and the Colville River for the time period 1947 to 2010. This baseline layer serves as the starting point for all transects cast by the DSAS application and can be used to establish measurement points used to calculate shoreline-change rates.

Migratory birds are important for recreation and tourism, contributing to a vibrant birdwatching industry in Alaska. Every spring, hundreds of birds migrate to their summer breeding grounds in Alaska and northern Canada. Their arrival is timed with the height of the spring green-up of plants, which provide the food necessary for birds to reproduce and raise their young. However, over the last fifty years, warming temperatures in Alaska as a result of climate change have prompted an earlier transition from winter to spring. The purpose of this project was to examine whether there have been changes in the timing of spring green-up in recent years (1985-2009) and, if so, whether migratory birds are adapting their migration...
