Modelling climate sensitivity of debris-covered glaciers
, 2022 The common occurrence of debris-covered glaciers in high-mountain areas makes their response to climate change relevant. The insulating effect of debris cover on surface melt causes debris-covered glaciers behave differently from debris-free glaciers, warranting the use of a specialized model for predictions.

Limnology and Oceanography: Methods, EarlyView.Abstract The integration of high‐throughput image–based flow cytometry into routine phytoplankton assessment requires rigorous evaluation against established microscopy techniques. As method agreement is often site‐ and species‐specific, case‐by‐case validation is essential to successfully adopt emerging methods.

Ablation process of debris-covered glaciers.
Journal of the Japanese Society of Snow and Ice, 2001 岩屑に覆われた永河の融解過程は複雑で観測が困難なためこれまで詳細な研究が少なかった.当初の研究は岩屑に覆われた部分に重点がおかれ,均一な厚さの岩屑に覆われた氷雪の融解についての実験的研究が多くの研究者によって行われてきた.実際の氷河では岩屑の粒径,組成,厚さなどの分布を広い面にわたって把握することが困難であった.そこで近年発達した衛星画像で得られた表面温度分布から消耗域全体の融解量を推定するモデルが開発された.このモデルにより推定された値は実際の岩屑に覆われた氷河の融解量よりも大きくなった.この原因は岩屑氷河の池や氷壁の部分で大きな熱の吸収が氷河の融解を促進させていることが一因と考えられる.

People and Nature, EarlyView.Abstract Fires are expanding in frequency and intensity worldwide due to climate change and land‐use transformations. At the same time, fire often plays a regenerative role in ecosystems. Traditional and cultural practices incorporate fire use for landscape management and landscape renewal. In this complex matrix of fire ecologies, digital technologies

, 2017 . We provide the first synoptic view of the drainage system of a Himalayan debris-covered glacier and its evolution through time, based on speleological exploration and satellite image analysis of Ngozumpa Glacier, Nepal.

Journal of Glaciology, 2019 Glaciological ablation is computed from point-scale data at a few ablation stakes that are usually regressed as a function of elevation and averaged over the area-elevation distribution of a glacier.

Glacial Loss and Threatened Fish: The Future of Mount Rainier's Cold‐Water Bull Trout Habitats
River Research and Applications, EarlyView.ABSTRACT Rivers supplied by glacial ice provide critical habitat for aquatic organisms that survive only in cold water, including federally threatened Bull Trout (Salvelinus confluentus). However, as glaciers retreat due to climate change, stream temperatures in key habitats could warm.

Aspect controls the survival of ice cliffs on debris-covered glaciers [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance Glaciers in High Mountain Asia (HMA) are important water sources for millions of people downstream. Ice cliffs on debris-covered glaciers act as hot spots for melt and may explain anomalously high glacier mass losses in HMA, but their temporal evolution remains unknown, hindering sound parameterizations of these features ...

Incorporating moisture content in surface energy balance modeling of a debris-covered glacier
The Cryosphere, 2019 . Few surface energy balance models for debris-covered glaciers account for the presence of moisture in the debris, which invariably affects the debris layer's thermal properties and, in turn, the surface energy balance and sub-debris melt of a debris ...
