Ecosystem-Based Fishery Management in the Bering Sea

Journal 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 [...]

Spectral roughness of glaciated bedrock geomorphic surfaces: Implications for glacier sliding [PDF]

, 2000
A microroughness meter (MRM) was used to measure the high-frequency roughness of a number of geomorphic surfaces in the forefield of Glacier de Tsanfleuron, Switzerland.

Mountain goat declines in a protected, interior, native population

Ecosphere
A shifting climate poses threats to alpine‐adapted species including mountain goats. We used long‐term (12 years) citizen science monitoring data and Bayesian N‐mixture modeling to estimate population trends and drivers of population metrics among ...

A New Method for Automatic Glacier Extraction by Building Decision Trees Based on Pixel Statistics

Remote Sensing
Automatic glacier extraction from remote sensing images is the most important approach for large scale glacier monitoring. Commonly used band calculation indices to enhance glacier information are not effective in identifying shadowed glaciers and debris-

Imprints of sea ice, wind patterns, and atmospheric systems on summer water isotope signatures at Hercules Névé, East Antarctica [PDF]

The Cryosphere
This study investigated the influence of summer climate variability on water isotopes (δ18O, δ2H, and deuterium excess[dexc]) in a Hercules Névé ice core from Antarctica.

Representing moisture fluxes and phase changes in glacier debris cover using a reservoir approach [PDF]

, 2014
Due to the complexity of treating moisture in supraglacial debris, surface energy balance models to date have neglected moisture infiltration and phase changes in the debris layer.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Quantifying lake expansion probability under compound glacier–climate forcing using a GCL-CPF framework integrating multi-source Earth observation and vine copula theory

International Journal of Applied Earth Observations and Geoinformation
Lakes across the Tibetan Plateau exhibit pronounced responses to climatic variability and glacier fluctuations. However, the compound effects of glacier and climate forcing on lake dynamics remain insufficiently quantified, owing to limited observational

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

The 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.
