Highlighted Data

Last Update: 2017-01-12
Point Measurements of Surface Mass Balance, Eklutna Glacier, Alaska, 2008-2015

This data set consists of a time-series of direct measurements of glacier surface mass balance, at Eklutna Glacier, Alaska. It includes seasonal measurements of winter snow accumulation and summer snow and ice ablation.

Fatty acid signature data of Chukchi Sea polar bears, 2008-2015

This dataset contains fatty acid data expressed as mass percent of total fatty acids for Chukchi Sea polar bears.

Avian Point Count, Habitat, and Covariate Data for Subarctic Bird Abundance, Seward Peninsula, Alaska, 2012-2014

This data release contains three tables of information: avian counts by species, habitat type, a covariate information used for analysis of bird surveys conducted between 2012 and 2014 on the Seward Peninsula, Alaska, as part of the USGS Changing Arctic Ecosystems Initiative. We conducted 1,208 point counts on 12 study blocks from 2012-2014 in northwestern Alaska, using repeated surveys to account for imperfect detection of birds. We considered the importance of shrub height, density of low and tall shrubs (i.e. shrubs >0.5 m tall), percent of ground cover attributed to shrubs (including dwarf shrubs <0.5 m tall), and percent of herbaceous plant cover in predicting bird abundance.
