Carbon Emissions from Boreal Forest Fires

Ignition locations and burned areas in Alaska, 2015

Ignition locations and burned area for Interior Alaska in 2015 (from Veraverbeke et al, 2017).

Researchers with NASA's ABoVE estimated the daily burned area and carbon emissions from boreal fires from 2001-2015.

Effects of Oil Exploration on Alaskan Vegetation

Alaskan researchers collected environmental data from 87 study plots near an abandoned test oil well in Oumalik, Alaska.

Arctic Vegetation in Kuparuk, Alaska

Glacial geology in the Upper Kuparuk River area of Alaska

Data released in support of NASA's ABoVE project provides vegetation, landscape, hydrology, and geologic maps for the Kuparuk River Basin in Alaska.

Tree mortality due to fires and bark beetles

Cumulative tree mortality from forest fires and bark beetles

Cumulative tree mortality due to (a) fires and (b) bark beetles from 2003-2012 on forestland in the western United States (from Berner et al., 2017, in review).

Wildfire and bark beetles caused tree mortality, and decreased carbon storage, in areas of the western USA from 2003-2012.

Is the snow melting earlier?

Mean snowmelt timing map

Mean snowmelt Day of Year (DOY) for the years 2001-2015 for North America. The DOY values for snowmelt timing were identified by observing the transition from snow-cover to no-snow for individual MODIS pixels throughout the annual melt period.

A new time-series analysis of snow cover has identified the day of snowmelt in each MODIS pixel across North America in each year from 2001 - 2015.
