Rapid coastal erosion in the ArcticThis video shows rapid coastal erosion at Drew Point, Alaska between 25 July and 25 August 2016. Images were captured at hourly intervals from a near real-time camera and were pieced together to create this time-lapse video. The video shows thermo-erosional niche formation and block collapse associated with an ice-rich, permafrost-influenced coastal bluff. During this month long period, some coastal segments retreated more than 6 meters.

Teshekpuk Lake - Arctic NurseryVideo courtesy of Audubon Alaska. Learn more at www.audubonalaska.org. Teshekpuk Lake is located on the North Slope of Alaska and is one of the most ecologically important wetlands in the entire Arctic. This sensitive area provides habitat for tens of thousands of molting geese, threatened species like the Spectacled Eider, and the 45,000-head Teshekpuk Lake Caribou Herd. This video was sponsored by Audubon Alaska and the Wildlife Conservation Society, in cooperation with the Cornell Lab of Ornithology. Support for Audubon's Western Arctic conservation program was provided by the Campion Foundation, the Conservation Alliance, the William and Flora Hewlett Foundation, the Wilburforce Foundation, and the 444 S Foundation.

Wetlands Live: Arctic Coastal Plain with Dr. ArpRecorded at the TLO in August 2012 - Dr. Christopher Arp talks about wetlands on the Arctic Coastal Plain of northern Alaska. Thermokarst lakes on the Arctic Coastal Plain began to form during the beginning of the Holocene around 10,000 years ago. Over time many of these lakes have drained creating a mosaic of lakes and drained lake basins which provides important diversity in habitat types in the region. One of the big questions that scientists face is the question: How will climate change influence the distribution of lakes and drained lake basins on the landscape and the animals that rely on them for habitat?

Understanding the winter regime of Arctic lakes
On March 1st IARC’s Alessio Gusmeroli collaborating with project leaders Christopher Arp (WERC) and Benjamin Jones (USGS) traveled 400 miles roundtrip from Toolik field station (68N) to the Colville River delta (70N) to observe lake-ice conditions in some of the numerous lakes in the area. The expedition lasted for seven days and windchill temperatures ranged from -30C to -50C during the field campaign. Arp and colleagues recently documented a shift in the thermal regime of Arctic lakes; such a shift may cause significant changes in the aquatic habitat, a critical component of the Arctic terrestrial food chain. Our measurements are being used to validate satellite imagery acquired for our study site on the same days that we were out conducting the ground surveys. These data are necessary to monitor and observe these sentinels of changing Arctic ecosystems. The team also made an outreach documentary, which helps illustrate the conditions that Arctic scientists often face while studying winter processes.
