Erosion along Alaska’s Arctic coastline near the village of Kaktovik
Erosion along Alaska’s Arctic coastline near the village of KaktovikNeal Pastick – lead author of the study – investigating erosion along Alaska’s Arctic coastline near the village of Kaktovik. Permafrost-dominated coasts of Alaska have drastically changed as the result of coastal transgression and storm-surge flooding which can result in the loss of cultural sites and damage to infrastructure.

Aerial view toward the southwest of the actively erupting cone within Veniaminof calderaAerial view toward the southwest of the actively erupting cone within Veniaminof caldera. The white steam plume is produced where a lava flow is descending the side of the cone and melting snow and ice. The darker colored, ashy plume is rising in bursts from the active vent.

A handful of adult ninespine stickleback
A handful of adult ninespine stickleback ready to be measured for total body length. These fish are ubiquitous in freshwater habitats of the Arctic Coastal Plain, outnumbering other fish species by as many as 800 individuals to one.
