New Technique Maps Large-scale Impacts of Fire-induced Permafrost Thaw in Alaska

Florida Atlantic University — Tue, 14 Feb 2023 08:30:47 EST

For the first time, researchers have developed a machine learning-based ensemble approach to quantify fire-induced thaw settlement across the entire Tanana Flats in Alaska, which encompasses more than 3 million acres. They linked airborne repeat lidar data to time-series Landsat products (satellite images) to delineate thaw settlement patterns across six large fires that have occurred since 2000. The six fires resulted in a loss of nearly 99,000 acres of evergreen forest from 2000 to 2014 among nearly 155,000 acres of fire-influenced forests with varying degrees of burn severity. This novel approach helped to explain about 65 percent of the variance in lidar-detected elevation change.

Researchers uncover secrets on how Alaska's Denali Fault formed

Brown University — Wed, 18 Jan 2023 17:45:19 EST

When the rigid plates that make up the Earth's lithosphere brush against one another, they often form visible boundaries, known as faults, on the planet's surface. Strike-slip faults, such as the San Andreas Fault in California or the Denali Fault in Alaska, are among the most well-known and capable of seriously powerful seismic activity.

Study Finds Growing Potential for Toxic Algal Blooms in the Alaskan Arctic

Woods Hole Oceanographic Institution — Tue, 05 Oct 2021 08:40:56 EST

Changes in the northern Alaskan Arctic ocean environment have reached a point at which a previously rare phenomenon--widespread blooms of toxic algae--could become more commonplace, potentially threatening a wide range of marine wildlife and the people who rely on local marine resources for food. That is the conclusion of a new study about harmful algal blooms (HABs) of the toxic algae Alexandrium catenella being published in the journal Proceedings of the National Academy of Science.

From Alaska to Florida, FAU's Third Sea-Level Rise Summit Will Generate Blueprint for Solutions and Adaptation

Florida Atlantic University — Fri, 08 Apr 2016 17:30:55 EST

While Florida and Alaska are on the opposite ends of the spectrum, they share mutual concerns of the imminent challenges presented by environmental changes. The rapid melting of the Arctic ice is threatening coastal locations globally, and impacts include increased flooding from sea-level rise in Florida to infrastructure instability from permafrost melting in Alaska.
