Impacts of tidewater glacier advance on iceberg habitat

open access: yesAnnals of Glaciology, 2023
Icebergs in proglacial fjords serve as pupping, resting and molting habitat for some of the largest seasonal aggregations of harbor seals (Phoca vitulina richardii) in Alaska.

Changes in Imja Tsho in the Mount Everest Region of Nepal [PDF]

open access: yes, 2014
Imja Tsho, located in the Sagarmatha ( Everest) National Park of Nepal, is one of the most studied and rapidly growing lakes in the Himalayan range. Compared with previous studies, the results of our sonar bathymetric survey conducted in September of ...

Hydraulic and mechanical properties of glacial sediments beneath Unteraargletscher, Switzerland: implications for glacier basal motion [PDF]

open access: yes, 2001
The force on a ‘ploughmeter’ and subglacial water pressure have been measured in the same borehole at Unteraargletscher, Switzerland, in order to investigate ice–sediment coupling and the motion at the base of a soft-bedded glacier.

Species conflict at Earth’s edges – Contests, climate, and coveted resources

open access: yesFrontiers in Ecology and Evolution, 2022
Direct conflict between species is an infrequently witnessed biological phenomenon. Potential drivers of such contests can include climate change, especially at Earth’s high elevation and latitudinal extremes where temperatures warm 2–5 times faster than

Ecosystem-Based Fishery Management in the Bering Sea

open access: yesJournal of Marine Science and Engineering, 2023
The waters of the Bering Sea are among the most productive on earth, having supported major commercial fisheries for up to ~60 years and First Nations cultures for millennia [...]

Melt regimes, internal stratigraphy, and flow dynamics of three glaciers in the Alaska Range [PDF]

open access: yes, 2012
We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska.

Worldwide Assessment of National Glacier Monitoring and Future Perspectives

open access: yesMountain Research and Development, 2019
It is widely accepted that glaciers are retreating throughout the world and that their decline causes serious impacts on many societies. Knowledge of glacier distribution and quantification of glacier changes is crucial to assessing the impact of glacier

Underwater Acoustic Ecology Metrics in an Alaska Marine Protected Area Reveal Marine Mammal Communication Masking and Management Alternatives

open access: yesFrontiers in Marine Science, 2018
Vessel-generated underwater noise can affect humpback whales, harbor seals, and other marine mammals by decreasing the distance over which they can communicate and detect predators and prey.

Response of Marine‐Terminating Glaciers to Forcing: Time Scales, Sensitivities, Instabilities, and Stochastic Dynamics [PDF]

open access: yes, 2018
Recent observations indicate that many marine‐terminating glaciers in Greenland and Antarctica are currently retreating and thinning, potentially due to long‐term trends in climate forcing.

Local topography increasingly influences the mass balance of a retreating cirque glacier [PDF]

open access: yesThe Cryosphere, 2018
Local topographically driven processes – such as wind drifting, avalanching, and shading – are known to alter the relationship between the mass balance of small cirque glaciers and regional climate.
