Continuous Loss of Global Lake Ice Across Two Centuries Revealed by Satellite Observations and Numerical Modeling

open access: yesGeophysical Research Letters, 2022
Lake ice loss has been detected worldwide due to recent climate warming, yet spatially and temporally detailed information on the changes in global ice phenology does not exist.

Southern Ocean Biogeochemical Argo detect under-ice phytoplankton growth before sea ice retreat [PDF]

open access: yesBiogeosciences, 2021
The seasonality of sea ice in the Southern Ocean has profound effects on the life cycle (phenology) of phytoplankton residing under the ice. The current literature investigating this relationship is primarily based on remote sensing, which often lacks ...

On thin ice: Linking elevation and long‐term losses of lake ice cover

open access: yesLimnology and Oceanography Letters, 2021
Despite long‐term analyses of lake ice phenology globally, comparatively little is known about high‐elevation lakes, for which climate shifts are thought to be occurring faster than at lower elevations. Using a 36‐yr dataset (1983–2018) on alpine lakes (>

Sea ice directs changes in bowhead whale phenology through the Bering Strait

open access: yesMovement Ecology, 2023
AbstractBackgroundClimate change is warming the Arctic faster than the rest of the planet. Shifts in whale migration timing have been linked to climate change in temperate and sub-Arctic regions, and evidence suggests Bering–Chukchi–Beaufort (BCB) bowhead whales (Balaena mysticetus) might be overwintering in the Canadian Beaufort Sea.MethodsWe used an ...

Sea ice and snow phenology in the Canadian Arctic Archipelago from 1997 to 2018

open access: yesArctic Science, 2021
The multiple islands and narrow channels that form the Canadian Arctic Archipelago (CAA) complicate snow/ice monitoring, as coarse resolution satellite observations are unable to resolve smaller-scale changes in snow/ice cover. We present the first study

Dominance of grain size impacts on seasonal snow albedo at deforested sites in New Hampshire [PDF]

open access: yes, 2017
Snow cover serves as a major control on the surface energy budget in temperate regions due to its high reflectivity compared to underlying surfaces.

Changes in Snow Phenology from 1979 to 2016 over the Tianshan Mountains, Central Asia [PDF]

open access: yes, 2019
Snowmelt from the Tianshan Mountains (TS) is a major contributor to the water resources of the Central Asian region. Thus, changes in snow phenology over the TS have significant implications for regional water supplies and ecosystem services.

Beavers on Ice: Factors Influencing Emergence Phenology in Boreal Canada. [PDF]

open access: yesGlob Chang Biol
Climate‐driven changes in ice phenology influence the timing of spring emergence of a non‐hibernating ice‐bound mammal, the North American beaver. ABSTRACT The influence of climate change on emergence phenology of hibernating mammals in northern latitudes is receiving increased attention, yet for freshwater semi‐aquatic mammals such as beavers, which ...
