USGS is flying drones for science, small uncrewed areal systems (sUAS), to surveys walruses when they rest on shore. The sUAS makes minimal sound due it is broad wing and is flown high above the walrus herds to enables survey data collection with minimal risk to walruses.

Two adult walrus carcasses on the beach observed during the summer after a large group of walruses had rested on shore. USGS is collaborating with the North Slope Borough Department of Wildlife Management to screen walruses for wildlife diseases and algal toxins.

This is a community flyer for distribution in Point Lay, Alaska, to alert community members of USGS activities in the area. A collaborative team of USGS, the North Slope Borough, University of Alaska Fairbanks, and Point Lay residents will assist in surveys of walrus carcasses at a remote coastal haulout that has been used by hundreds of thousands of walruses e

Glory of Russia Cape, named by Russian Polar explorer, Gavril Sarychev, is the northernmost point of St. Matthew Island. The cape is best know for the 1989 shipwreck of the Greek ship "Milos Reefer". The rusted and battered haul is still visible below the rocky cliffs.

Pairs of Common Murre (Uria aalge; chocolate-colored hue) and Thick-billed Murre (Uria lomvia; black-colored hue) nest along the sea cliffs of a grotto on St. Matthew Island. The island is home to over 1.6 million nesting seabirds, including cormorants, kittiwakes, puffins and auklets.

Woolly lousewort (Pedicularis lanata), also known as "bumble-bee flower" are native to the alpine regions of Alaska, Canada, and Greenland. This compact and hardy plant can withstand even the strongest Bering Sea winds. The "wool", as it is known, is a layer of fuzzy insulation, which wraps around the steam of the plant, protecting it from wind and cold.

The lower jawbone of an adult male walrus rests on the sandy shore of St. Matthew Island, Alaska. The Pacific Walrus (Odobenus rosmarus) is a large pinniped that occurs within the Bering and Chukchi Sea regions. Although more commonly observed on the mainland coast of western Alaska, walrus "haulouts" have been observed on St.

Arctic primrose are native to the alpine regions of Alaska, Yukon, Northwest Territories and Far Eastern Russia. On St. Matthew Island, these flowers are typically observed on moist alpine slopes where snow remains long into the summer months. The flower was observed while conducting McKay's Bunting and Rock Sandpiper distance-sampling surveys on St.

A pair of skiffs sit atop the R/V Tiglax on a cold summer morning in the Bering Sea. It is not uncommon for snow showers any time of the year in the Bering Sea region, however, this particular visit to St. Matthew proved to be extra chilly, as it never reaches over 40 degrees Fahrenheit into mid-June.

The McKay's Bunting (Plectrophenax hyperboreus) is endemic to the Bering Sea Region and only breeds on St. Matthew Island. Designated as a species of high conservation concern due to its small population size, surveys show that the species has continued to decline since the initial survey effort in 2003.

The Pribilof Rock Sandpiper (Calidris ptilocnemis ptilocnemis) is endemic to the Bering Sea Region and only breeds on the islands of St. Matthew, Hall, St. Paul, and St. George. The Rock Sandpiper is one of two focal species monitored as part of a long-term population study led by USGS Alaska Science Center, U.S.

During the summer months on St. Matthew Island the sun never truly sets. The amber hues on the horizon serve as the perfect backdrop to a long, yet successful, day conducting Rock Sandpiper and McKay's Bunting distance-sampling surveys. The sunset photo was taken at 12:10am.

The St. Matthew Island LORAN station began operation by the Coast Guard on July 10, 1944. The station closed on September 13, 1946. Although equipment was removed from the island a few years after the station was closed, large and heavy objects were left behind, including this toilet, which stands in nearly pristine condition.

Cape Upright is located on the southeasternmost point of St. Matthew Island and is comprised of rocky tundra and towering cliffs that reach over 1,000 feet. The point was named by Captain James Cook on July 29, 1778. This view was observed while conducting McKay's Bunting and Rock Sandpiper distance-sampling surveys on St. Matthew Island.

In August of 1944, 29 Nunivak Island reindeer were transported to St. Matthew Island via barge as a free-range food source for the Coast Guard officials that maintained the long-range navigation site (Loran) during World War II. At the peak, 6,000 reindeer roamed the island at a density of 47 animals per square mile.
