KUAC in Alaska is featuring our 2015 research on the Tanana River near Fairbanks, AK and in the Yukon Flats, north of the Arctic Circle. Here is the link to their piece: http://fm.kuac.org/post/nasa-tracks-alaska-waters

President Obama to address GLACIER conference. Plus new article on Alaska Natives and Climate Change
Alaska is receiving a great deal of attention this week as President Obama arrives to address the GLACIER - Global Leadership in the Arctic - conference in Anchorage tomorrow (Monday 31-August-2015). The president will also visit outlet glaciers in the Kenjai fjords as well as rural Arctic villages. It has also been announced that the President will officially rename "Mt. McKinley" to "Denali", the original Alaska Native name given to the tallest peak in North America.
In preparation, the Los Angeles Times published an article about climate change and its pronounced affect on a rural village in Alaska. Check out the article here: http://www.latimes.com/nation/la-na-arctic-obama-20150830-story.html
In April 2015 we installed a radar level sensor on the bridge in Kangerlussuaq, Greenland to monitor water levels in near real time in one of the largest glacial fed rivers in Greenland. We partnered with Dave Finnegan and Adam LeWinter at CRREL to design and install the sensor.
Here are some photos of Adam LeWinter and I completing the installation in April 2015.
Check out the case study that Sutron put together about our installation and a pdf of the Sutron Project Profile report.
New Paper: "Technical Note: Semi-automated effective width extraction from time-lapse RGB imagery of a remote, braided Greenlandic river"
Check out our new paper:
Technical Note: Semi-automated effective width extraction from time-lapse RGB imagery of a remote, braided Greenlandic river
This paper discussing our use of time-lapse cameras to monitor Greenland Ice Sheet meltwater outflow in a large braided river in western Greenland.
At left, is a picture I took in August 2013 of Colin J. Gleason (UCLA - Department of Geography), lead author of this study, servicing these time-lapse cameras for the winter. At right is a picture of the Isortoq River flowing from the Issungata Sermia glacier in western Greenland to the ocean.

An estimated 21,000 gallons of crude oil have leaked from a Plains All American Pipeline near Refugio State Park, along the Gaviota Coast north of Santa Barbara, California. Reportedly, an oil slick roughly 4-miles long and 50-100 yards wide extends off the coast of Refugio State Park Beach.
This is an eery reminder of Union Oil's 1969 oil spill off the coast of Santa Barbara - which had significant ecological and environmental impacts on coastal Santa Barbara County.
In lieu of Governor Jerry Brown's announcement to imposed 25% water consumption cuts, the New York Times released this very interesting interactive map displaying current water consumption in California both in summer and in winter.

The NASA/JPL Airborne Snow Observatory released a new study finding that the Tuolumne Basin Snowpack contains just 40% snow water equivalent that it did at its highest level in 2014. More about this research can be found here: http://www.nasa.gov/jpl/nasa-california-tuolumne-snowpack-40-percent-of-worst-year/index.html
Heading into summer, this is dismal news for the pronged drought in California.

My name is Lincoln H Pitcher. I am a graduate student in the Department of Geography at UCLA. My research focuses hydrologic and cryospheric systems and interfaces with emerging ground, air and spaceborne remote sensing and geospatial technologies. I aim to use these emerging technologies to enhance understanding of remote and logistically inaccessible places. My current research focuses on both Greenland and Arctic Alaska.
