USGS Arctic researchers aimed a cellular-connected camera, used for tracking game, on another camera system as a means to keep an eye on the integrity of those video cameras “across the way.” What's funny is that the game cam went offline over the cold winter, and the scientists thought they'd lost it. Then suddenly, on April 15th, the game cam emailed an image! The one shown here is a bit more colorful and from a few days later, on April 19th. Now they know that #1 this game cam is still working (but just got a little frozen!) and #2 that their tower for mounting video cameras (used to observe and quantify coastal processes) is still standing and ready for summer installation.

Read more about our ongoing research about climate impacts to Arctic coasts, and how we use video imagery to study coastal change in Barter Island, Alaska.

July 2018

In July 2018, three USGS Pacific Coastal and Marine Science Center researchers installed thermometers, video cameras, a seismometer, and a wave gauge to measure permafrost temperatures and bluff erosion on the Arctic Ocean coast of Barter Island, Alaska. Combined data from these instruments will be used to test the possibility of remotely estimating wave heights without installing and maintaining wave gauges in the ocean. USGS oceanographer Shawn Harrison devised and lead the installation of video cameras and seismometer. Coastal erosion along the Arctic coast of Alaska threatens Native Alaskan villages, sensitive ecosystems, energy- and defense-related infrastructure, and large tracts of Native Alaskan, State, and Federally managed land. The scientists also hosted a community outreach event to present results from earlier studies and to discuss their ongoing research. Government officials, residents, and non-residents attended the event. PCMSC researchers particularly appreciated the local coastal information, insights, and concerns provided by long-time community residents.
View photos of the installation process for the cameras and the seismometer below.

USGS scientist Cordell Johnson points to the Raspberry Shake, a sensitive instrument used to detect ground shaking. Johnson mounted the Raspberry Shake to an aluminum pole which he will then drive into the ground to bury the instrument beneath the tundra. This process will help isolate it from the wind.

This device, called a Raspberry Shake, is a sensitive instrument used to detect ground shaking. It is being carefully buried in this shallow hole in the tundra, to isolate it from wind.

Climate impacts to Arctic coasts

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.

Coastal Climate Impacts

The impacts of climate change and sea-level rise around the Pacific and Arctic Oceans can vary tremendously. Thus far the vast majority of national and international impact assessments and models of coastal climate change have focused on low-relief coastlines that are not near seismically active zones. Furthermore, the degree to which extreme waves and wind will add further stress to coastal...
