Detecting mass wasting of Retrogressive Thaw Slumps in spaceborne elevation models using deep learning

Climate change has led to stronger warming in the Arctic, causing higher ground temperatures and extensive permafrost thaw. Retrogressive Thaw Slumps (RTSs) represent one of the most rapid and considerable geomorphological changes in permafrost regions, oc ...

network-based constraint to evaluate climate sensitivity

Athanasios Nenes, Lucile Anna Ricard

The 2015 Paris agreement was established to limit Greenhouse gas (GHG) global warming below 1.5°C above preindustrial era values. Knowledge of climate sensitivity to GHG levels is central for formulating effective climate policies, yet its exact value is s ...

Identifying airborne snow metamorphism with stable water isotopes

Michael Lehning, Sonja Wahl

Abstract. Wind-blown snow is a frequent phenomenon in high-elevation and polar regions which impacts the surface energy and mass balance of these areas. Loose surface snow gets eroded and transported by wind, which influences the snow particles' physical p ...

Superconducting Gravimeter Observations Show That a Satellite-Derived Snow Depth Image Improves the Simulation of the Snow Water Equivalent Evolution in a High Alpine Site

Michael Lehning

The lack of accurate information on the spatiotemporal variations of snow water equivalent (SWE) in mountain catchments remains a key problem in snow hydrology and water resources management. This is partly because there is no sensor to measure SWE beyond ...

Perturbations of heterotrophs and autotrophs in tidally dynamic coastal sediments: Development of a scalable model

Zhaoyang Luo

Tidal wetlands undergoing regular tidal inundation contribute more than 60% CO(2) uptake of the coastal ocean. However, a comprehensive understanding of tidal microbial spatial distribution is poorly known, giving rise to previously ignored perturbations o ...

CO2 storage in basalts: the impact of mineralisation on the hydromechanical response of the material

Lyesse Laloui, Eleni Stavropoulou

Carbon mineralisation in basalts is a promising cost-effective way to permanently store CO2 in view of climate change mitigation. In this work, the impact of carbon mineralisation on the hydromechanical properties of a basaltic sample is studied. Unlike pr ...

Comparative Population Transcriptomics Provide New Insight into the Evolutionary History and Adaptive Potential of World Ocean Krill

Gaëlle Delphine Toullec

Genetic variation is instrumental for adaptation to changing environments but it is unclear how it is structured and contributes to adaptation in pelagic species lacking clear barriers to gene flow. Here, we applied comparative genomics to extensive transc ...

Spatially adaptive machine learning models for predicting water quality in Hong Kong

Rongrong Li

Water quality prediction in the spatially heterogeneous environment is challenging as the importance of water quality parameters (WQPs) and the performance of prediction models may vary across space. Thus, this study proposed spatially adaptive machine lea ...

Strategic factors to design the next generation of molecular water oxidation catalysts: Lesson learned from ruthenium complexes

Mohammad Khaja Nazeeruddin

Energy conversion through sustainable means is essential to counter global warming and an urgent solution through a multidisciplinary approach is required. The temperature change stems from the emission of greenhouse gases largely contributed by burning fo ...

Positive interactions between corals and damselfish increase coral resistance to temperature stress

Leïla Ezzat

By the century's end, many tropical seas will reach temperatures exceeding most coral species' thermal tolerance on an annual basis. The persistence of corals in these regions will, therefore, depend on their abilities to tolerate recurrent thermal stress. ...

Hydrological trends and the evolution of catchment research in the Alptal valley, central Switzerland

Jana Freiin von Freyberg, Ilja van Meerveld

When the observation of small headwater catchments in the pre-Alpine Alptal valley (central Switzerland) started in the late 1960s, the researchers were mainly interested in questions related to floods and forest management. Investigations of geomorphologi ...

Drainage Canals in Southeast Asian Peatlands Increase Carbon Emissions

Mateusz Kozinski, Doruk Oner

Drainage canals associated with logging and agriculture dry out organic soils in tropical peatlands, thereby threatening the viability of long-term carbon stores due to increased emissions from decomposition, fire, and fluvial transport. In Southeast Asian ...

Optical properties and photochemical production of hydroxyl radical and singlet oxygen after ozonation of dissolved organic matter

Urs von Gunten, Frank Jonathan Leresche

This study focuses on the effects of ozonation on the optical and photochemical properties of dissolved organic matter (DOM). Upon ozonation, a decrease in light absorption properties of DOM was observed concomitantly with a large increase in singlet oxyge ...

Hotter droughts alter resource allocation to chemical defenses in pinon pine

Charlotte Grossiord

Heat and drought affect plant chemical defenses and thereby plant susceptibility to pests and pathogens. Monoterpenes are of particular importance for conifers as they play critical roles in defense against bark beetles. To date, work seeking to understand ...

Modeling the coupled dynamics of stream metabolism and microbial biomass

Tom Ian Battin, Enrico Bertuzzo, Pier Luigi Segatto

Estimating and interpreting ecosystem metabolism remains an important challenge in stream ecology. Here, we propose a novel approach to model, estimate, and predict multiseasonal patterns of stream metabolism (gross primary production [GPP] and ecosystem r ...

Changes in Climatology, Snow Cover, and Ground Temperatures at High Alpine Locations

Michael Lehning

Knowledge about changes in ground temperatures under a changing climate is important for many environmental, economic, and infrastructure applications and can be estimated by transient numerical simulations. However, a full annual cycle of precipitation da ...

Accessing Monosubstituted Cyclopentadienyl Rhodium(I) and Iridium(I) Complexes by a Simultaneous Nucleophilic Addition-Metalation Approach to Fulvenes

Nicolai Cramer, Aragorn Nathan Laverny

Despite advances in the synthesis of polysubstituted cyclopentadienyl metal complexes, the rapid access to a library of monosubstituted Cp bearing metal complexes remains challenging. A convenient and general method to access a broad range of monosubstitut ...

Predicting ambient aerosol thermal–optical reflectance (TOR) measurements from infrared spectra: extending the predictions to different years and different sites

Satoshi Takahama, Matteo Reggente

Organic carbon (OC) and elemental carbon (EC) are major components of atmospheric particulate matter (PM), which has been associated with increased morbidity and mortality, climate change, and reduced visibility. Typically OC and EC concentrations are meas ...
