Evaluating RADARSAT-2 for the Monitoring of Lake Ice Phenology Events in Mid-Latitudes

Remote Sensing, 2018
Lake ice is an important component in understanding the local climate as changes in temperature have an impact on the timing of key ice phenology events. In recent years, there has been a decline in the in-situ monitoring of lake ice events in Canada and

Low‐temperature soft electrochemical actuator based on hierarchically structured polypyrrole membranes for subzero operation

FlexMat, EarlyView.
A soft electrochemical actuator using a hierarchically structured polypyrrole membrane with coral‐like hollow vesicles achieves stable performance at −24°C. The unique architecture ensures continuous conductivity and rapid ion diffusion, resulting in large strain, low energy consumption, and high coulombic efficiency under subzero conditions. This work

Future Range Shifts and Diversity Patterns of Antarctic Lecideoid Lichens Under Climate Change Scenarios

Global Change Biology Communications, EarlyView.
Modeling of current and future spatial distribution of Antarctic lecideoid lichens shows that warming will strongly increase the potential habitat. Under three climate‐change scenarios, most fungal and algal partners are projected to expand inland. Overall, climate change drives widespread range shifts and promotes colonization of interior Antarctica ...

Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

Global Change Biology Communications, EarlyView.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

Proglacial Lake Drainage Events Drive Fast Grounding Line Advance in a Warming Climate

Geophysical Research Letters
Proglacial lakes along the retreating margin of the Laurentide ice sheet (LIS) significantly influenced the ice sheet's dynamics. This study investigates the interaction between proglacial lake drainage events and ice sheet evolution during deglaciation.

Neoarchean Arc Magmatism and Crust Recycling in the Northern Marginal Zone of the Limpopo Complex, Zimbabwe: New Insights From Zircon U‐Pb‐Hf Isotopes of a Charnockite Suite

Geological Journal, EarlyView.
Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

Origins of the Pangkaimen Au Deposit in the Northern Great Xing'an Range, China: Evidence From Geochronological, Geochemical, Fluid Inclusion, and H–O–S–Pb Isotope Data

Geological Journal, EarlyView.
The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...
