Black bear density in Glacier National Park, Montana
Wildlife Society Bulletin, 2014 We report the first abundance and density estimates for American black bears (Ursus americanus) in Glacier National Park (NP), Montana, USA. We used data from 2 independent and concurrent noninvasive genetic sampling methods—hair traps and bear rubs ...

A seismic analysis of subglacial lake D2 (Subglacial Lake Cheongsuk) beneath David Glacier, Antarctica [PDF]
The CryosphereSubglacial lakes beneath Antarctic glaciers are pivotal in advancing our understanding of cryosphere dynamics, basal hydrology, and microbial ecosystems. We investigate the internal structure and physical properties of Subglacial Lake D2 (SLD2), which is

When Do Single‐Species Occupancy Models Outperform Multispecies Models?
Ecology and EvolutionOccupancy models have become increasingly popular for species monitoring and assessment, in part, because detection/non‐detection data are readily obtained using a variety of methods.

Seismic Imaging of the Arctic Subsea Permafrost Using a Least-Squares Reverse Time Migration Method
Remote SensingHigh-resolution seismic imaging allows for the better interpretation of subsurface geological structures. In this study, we employ least-squares reverse time migration (LSRTM) as a seismic imaging method to delineate the subsurface geological structures ...

Scientific ReportsAntarctic lakes are extreme, oligotrophic habitats that contain microbial communities distinct from those of temperate freshwater systems. Our central question was whether these lakes host microbial communities distinct from those of non-Antarctic ...

Development of Petrov glacial-lake system (Tien Shan) and outburst risk assessment
Лëд и снег, 2015 Global climate warming causes an intensive melting and retreat of glaciers in the Tien Shan mountains. Melting water of glaciers causes overfilling of high mountain lakes.

Changes of Marukh Glacier from 1945 to 2011
Лëд и снег, 2015 Field studies have been carried out in summer 2011 at Marukh Glacier located in western part of the Northern Caucasus. The studies included ground-based radio-echo sounding measurements at a frequency of 20 MHz and glacier surface elevation survey using ...

Glacierized headwater streams as aquifer recharge corridors, subarctic Alaska
Geophysical Research Letters, 2017 Arctic river discharge has increased in recent decades although sources and mechanisms remain debated. Abundant literature documents permafrost thaw and mountain glacier shrinkage over the past decades. Here we link glacier runoff to aquifer recharge via
