Moisture inversions in the central Arctic: Product assessment and long‐wave radiative effect
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study evaluates the integrated water vapour and the vertical distribution of water vapour of state‐of‐the‐art reanalyses, weather forecast models, and ground‐ and space‐based remote‐sensing products in the central Arctic. A particular focus lies on the representation of humidity inversions and the quantification of the long‐wave radiative effect ...

Polar‐low track prediction using machine‐learning methods
Quarterly Journal of the Royal Meteorological Society, EarlyView.Machine‐learning models are developed to produce reliable and efficient forecasts of polar‐low (PL) trajectories 12 hours ahead. A temporal model (RLSTM) benefiting from the rolling‐forecast strategy, improves overall prediction accuracy and is suitable for quick experimentation, while a spatiotemporal model (PL‐UNet), incorporating both historical and

Multilevel Cloud Structures over Svalbard
Monthly Weather Review, 2017 Abstract The presented picture of the month is a superposition of spaceborne lidar observations and high-resolution temperature fields of the ECMWF Integrated Forecast System (IFS). It displays complex tropospheric and stratospheric clouds in the Arctic winter of 2015/16.

TAXON, EarlyView.Abstract This study investigates species boundaries in the lichen genus Arctomia (Arctomiaceae, Ascomycota) using an integrative approach combining molecular phylogenetics, full Bayesian population delimitation, heuristic and model‐based species delimitation, and supervised machine learning applied to morphological data.

Wildlife Biology, EarlyView.Humans are often perceived as predators by free‐living animals, and thus, even non‐consumptive human activities such as outdoor recreation may trigger behavioural and physiological responses, often with negative consequences on individual fitness and population persistence.

Brute force prey metabarcoding to explore the diets of small invertebrates
Ecology and EvolutionPrey metabarcoding has become a popular tool in molecular ecology for resolving trophic interactions at high resolution, from various sample types and animals. To date, most predator–prey studies of small‐sized animals (

On the tidal forcing of an Arctic coastal polynya—Storfjorden polynya
Arctic ScienceStorfjorden in eastern Svalbard is known to be an “ice factory” during winter and a key dense water formation site due to its recurring coastal polynya.

The Svalbard Fisheries Protection Zone: How Russia and Norway Manage an Arctic Dispute
Арктика и Север, 2020 Svalbard and the maritime zone around this Arctic archipelago are central to Norway–Russia rela-tions. Since 1977, a dispute has concerned Norway’s right to exercise jurisdiction over fisheries.
