Detailed Description
Alaska’s landscapes are changing at a more rapid rate than those of the lower 48. Its large size makes the collection of aerial surveys—a biannual occurrence for the conterminous United States—cost-prohibitive. That means the Landsat series of land imaging satellites offer the only publicly available, up-to-date imagery of land conditions for Alaska. Landsat satellites underpin public and private sector decisions in the State and across the Nation for effective adaptation to changing landscapes.

Image of the Week: Glacial Retreat Fills Alaska Lake
The visible impact of climate change on the Earth’s surface is often clearest in the Arctic’s receding glaciers and swelling glacial lakes. Southeastern Alaska’s Harlequin Lake is one of the fastest-growing in North America. These false color Landsat images show the rapidly-retreating Yakutat Glacier, which feeds the lake.

The Arctic is changing at a more rapid rate than the rest of the planet. Some of the most significant changes are tied to the thawing of near-surface permafrost, the layers of frozen soil containing vast stocks of stored carbon.

The Shishaldin Volcano on the eastern edge of Alaska's Aleutian Island chain erupted with activity in January of 2020. The eruption on the island of Unimak sent an ash cloud nearly 5 miles into the sky on January 7th, sparking ash alerts for aviators, mariners, and residents of nearby communities.

Unlike the South Pole, the geographic North Pole does not lie on a land mass. The Earth’s northern axis of rotation is in the Arctic Ocean, covered by shifting sea ice.
Landsat does not image the North Pole, which makes it an imperfect investigative tool for the detection of Santa’s workshop.

The Landsat archive has added its 8 millionth scene. This stunning image was captured by Landsat 8 on July 28, 2018. It shows the coastline of Nordaustlandet, the second-largest island in Norway’s Svalbard archipelago.

Landsat sensor technology has come a long way since the days of the Return Beam Vidicon cameras on the first three Landsat satellites. Known as the RBV, it wasoriginally intended to be the satellites’ primary sensor. But the Multispectral
Scanner, or MSS, became the more stable and superior instrument.

The Landsat archive, the world's longest continuously acquired collection of space-based, moderate-resolution land remote sensing data, has now surpassed 7 million scenes since Landsat 1 first began collecting data in July 1972.

On June 28, 2016, a 4,000-foot-high mountainside in Glacier Bay National Park and Preserve collapsed, sending rocky debris equivalent to 60 million mid-size SUVs tumbling onto nearby Lamplugh Glacier.

This Landsat satellite imagery was acquired in August 2009, from the USGS-Earth Resource and Observation Science Center web page, https://www.usgs.gov/centers/eros/data-tools. This Landsat Enhanced Thematic Mapper Plus satellite image was augmented to detect submerged aquatic vegetation in Chignik

The tongue of the Malaspina Glacier, the largest glacier in Alaska, fills most of this image. The Malaspina lies west of Yakutat Bay and covers 1,500 sq mi (3,880 sq km).

These cloud formations were seen over the western Aleutian Islands. Their color variations are probably due to differences in temperature and in the size of water droplets that make up the clouds.

Within days of the launch, Landsat 1 acquired an image of an astounding 81,000-acre (327.8 square kilometers) fire burning in isolated, central Alaska. For the first time ever, scientists and resource management officials were able to see the full extent of damage from a fire in a single image while it was still burning.

The surface of the Earth is always changing. Some changes like earthquakes, volcanoes, floods, and landslides happen quickly, and other changes, such as most erosional processes, happen slowly over time. It’s often hard to see these changes from ground level. Earthshots shows you how satellite data are used to track these changes over time.
