The Arctic region is warming faster than anywhere else in the nation. Understanding the rates and causes of coastal change in Alaska is needed to identify and mitigate hazards that might affect people and animals that call Alaska home.

The increasing risk of flooding along our coasts is driven by climate change, development and habitat loss.

During a recent dive on the New England Seamount chain off the North Atlantic coast, researchers aboard the NOAA Ocean Exploration Expedition, North Atlantic Stepping Stones, discovered a marine geological feature known as a ferromanganese (Fe-Mn) nodule field in the saddle between two peaks of Gosnold Seamount.

The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards during storms. The protective services of these natural defenses are not assessed in the same rigorous economic terms as artificial defenses, such as seawalls, and therefore often are not considered in decision-making.

Title: Sea-Level Rise, Extreme Water Levels, and Coastal Erosion ... How bad could it possibly be?

In the spring, winter sea ice thaws and moves offshore leaving the coast exposed to increased wave action and relatively warm water temperatures that, when in contact with the bluff, erodes the toe of the bluff.

Recorded June 1, 2019 - August 18, 2019: Video shows a series of photos taken every hour during daylight hours in the summer of 2019. The camera looks westward along the coastal bluffs of Barter Island, located on Alaska’s North Slope.
