Final Results From the Circumarctic Lakes Observation Network (CALON) Project [PDF]

, 2015
Since 2012, the physical and biogeochemical properties of ~60 lakes in northern Alaska have been investigated under CALON, a project to document landscape-scale variability of Arctic lakes in permafrost terrain.

The IceShark, an effective method for sampling plankton under sea ice

Limnology and Oceanography: Methods, EarlyView.
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Interfacial Energy and Composition Controlled Self‐Stratification in Polyurethane Coatings

Macromolecular Materials and Engineering, EarlyView.
This study elucidates self‐stratification in polyurethane coatings driven by interfacial energies and composition‐dependent phase separation. Using XPS, SIMS, and Raman analyses, we reveal rapid formation of hydrophobic and hydrophilic layers and substrate‐dependent interfacial structures.

Parkinson's‐Linked LRRK2 and GBA1 Mutations Modulate the Peripheral Immune Response to Pseudomonas aeruginosa

Movement Disorders, EarlyView.
Abstract Background Peripheral disease mechanisms such as immune dysregulation may contribute to Parkinson's disease (PD). To investigate interactions between common PD mutations and immune responses to environmental pathogens, we studied responses to Pseudomonas aeruginosa (P.

Skeletal Muscle Microbiopsies in Children and Adults—Tolerability, Sample Yield, and Analyzability

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Traditional methods of sampling skeletal muscle tissue are invasive. This study aimed to evaluate a sub‐millimeter core‐biopsy (microbiopsy) as a potentially more tolerable method, with further regard to tissue yield and analyzability of RNA expression.

Saplings of significance: Nurturing cultural value of new tree plantings through participatory opportunities

People and Nature, EarlyView.
Abstract Tree‐planting initiatives are a crucial part of international sustainability and climate action efforts. Yet, many of these initiatives fail to achieve their long‐term sustainability and climate goals. The role of community value is an often‐overlooked factor in promoting the success of new tree plantings.

Permafrost Mass Wasting in Ice‐Rich Landscapes: Recent Advances (2013 to 2024) on Mechanisms, Dynamics and Impacts

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 ...

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

Effects of Surface Characteristics on the Existence of Isolated Permafrost in Northeastern Mongolia

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Isolated patches of permafrost, where ground thermal changes are affected by ecosystem factors such as vegetation cover rather than climate, may be vulnerable to environmental disturbances in semiarid regions. However, the impacts of ecosystem factors remain underevaluated in Mongolia.
