Global Solar-Induced Chlorophyll Fluorescence (SIF)

Solar-induced chlorophyll fluorescence.

Predicted spatially contiguous solar-induced chlorophyll fluorescence (SIF) across the United States for August 1 - 16, 2015. Areas of high SIF are in red, and areas of low SIF are in blue. Agricultural areas, like the U.S. Midwestern corn belt, often have a high rate of photosynthetic production which results in high SIF.

High-resolution, global, estimates of SIF based on data from the OCO-2 satellite serve as a proxy for rates of terrestrial photosynthesis.

Changing Availability of Subsistence Resources in Alaska

Lake grass vegetation at Tok.

This photo from June 2016 shows the "extreme" growth of lake grass in a lake near the Tok Community, Alaska.

ABoVE researchers worked with rural communities to document environmental changes that affect access to subsistence resources.

Highlights from the Literature

Mapping Global Mangrove Forests

Mangrove cover and height.

Heights of mangrove forests along the northern coast of Borneo (countries Brunei and Malaysia) reach 39 meters tall. Mangrove cover is illustrated in orange, where darker orange represents taller canopies.

Maps of the global distribution and biomass of mangrove forests are available for 116 countries.
