Limnology and Oceanography: Methods, EarlyView.Abstract Imaging Pulse Amplitude Modulation (PAM) fluorometry allows spatially resolved measurements of Photosystem II (PSII) fluorescence kinetics through time without disturbing study organisms or their environments. In particular, the use of photosynthesis–irradiance curves (P–I curves) provides detailed information on PSII quantum efficiency ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

Geophysical Research LettersThe melting of glaciers by ocean waters along the ice sheet periphery is a major physical process driving glacier evolution in a changing climate. Using a fiber‐optic‐tethered Grounding line Remote Operated Vehicle, we explore the ice shelf cavity of ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

Distributed acoustic sensing of microseismic sources and wave propagation in glaciated terrain
Nature Communications, 2020 In this study, Walter and colleagues deploy a 1 km long fiber optics cable on a glacier surface. Via the use of distributed acoustic sensing, the authors are capable of monitoring glacier dynamics and Alpine mass movements.

Boreas, EarlyView.Crater lakes in core regions of former ice sheets have the potential to preserve long‐term sedimentary archives that are otherwise rare in glaciated landscapes due to pervasive glacial erosion. Lake Wiyâshâkimî, an impact crater lake located in the inner core of the Québec‐Labrador Dome of the Laurentide Ice Sheet, provides a rare example of such a ...

Exploring the submarine geomorphology of Te Rua-o-te-Moko Fiordland, Aotearoa New Zealand
Frontiers in Earth ScienceTemperate fjords serve as key environments for understanding glacial landscape evolution, sedimentary processes, and dynamics. These overdeepened, glacially carved inlets serve as high-resolution repositories of past climate and ice behaviour.

Glaciological Literature [PDF]
Journal of Glaciology, 1974 AbstractThis is a selected list of glaciologcal literature on the scientific study of snow and ice and of their effects on the Earth; for the literature on polar expeditions, and also on the “applied” aspects of glaciology, such as snow ploughs, readers should consult the bibliographies in each issue of Recent Polar Literature (supplement to the Polar ...

Estimating the characteristics of runoff inflow into Lake Gojal in ungauged, highly glacierized upper Hunza River Basin, Pakistan [PDF]
, 2013 Motivated by the potential flood outburst of Lake Gojal in the ungauged highly glacierized (27%) upper Hunza River Basin (HRB) in Pakistan that was dammed by a massive landslide on 4 January 2010, we attempt to analyze the characteristics of water inflow
