Monitoring Tundra Travel Across the National Petroleum Reserve-Alaska

Submitted by atripp on Wed, 05/19/2021 - 10:57

Alaska is the only Arctic State in the Nation. The Arctic environment presents some unique challenges to living, working, and operating, including a lack of road infrastructure, high costs of shipping freight, and seasonal daylight limitations during the winter. The sun drops below the horizon in November and does not rise above the horizon until mid-February.

Using Temperature to Detect Active Carbonate Precipitation in Lakes

Submitted by atripp on Mon, 04/06/2020 - 13:10

Carbonate precipitation can occur where groundwater enters lakes and supplies chemicals missing from the lake, creating carbonate mounds called tufa mounds or microbialites. These precipitates can often be associated with microbes that either create micro-environments that encourage precipitation or act as templates for precipitation.

Submitted by atripp on Wed, 04/01/2020 - 14:15

Low-lying island environments, such as the Majuro Atoll in the Republic of the Marshall Islands, are particularly vulnerable to coastal flooding (inundation) whether the increased water levels are from episodic events (storm surge, wave run-up, king tides) or from chronic conditions (long-term sea-level rise). Land elevation is the primary environmental variable that determines exposure to inundation in coastal settings.

RiverView: Another Point of View for Remote Sensing

Submitted by atripp on Tue, 03/31/2020 - 15:25

BOR is a key partner in the Trinity River Restoration Program (TRRP), located in far northern California. Remote sensing for the TRRP includes annual high-resolution aerial photography (0.5-foot pixel resolution), which provides a standard point of view for detecting morphological and vegetation changes to the river channel and floodplain.

National Land Imaging Program Requirements, Capabilities and Analysis Activities
