Future sea ice weakening amplifies winddriven trends in surface stress and Arctic Ocean spin-up
(Nature Communications;15, Journal article, 2024-07)Arctic sea ice mediates atmosphere-ocean momentum transfer, which drives upper ocean circulation. How Arctic Ocean surface stress and velocity respond to sea ice decline and changing winds under global warming is unclear. ... -
Reduced Deep Convection and Bottom Water Formation Due To Antarctic Meltwater in a Multi-Model Ensemble
(Journal article, 2023)The additional water from the Antarctic ice sheet and ice shelves due to climate-induced melt can impact ocean circulation and global climate. However, the major processes driving melt are not adequately represented in ... -
Upper ocean warming and sea ice reduction en the East Greenland current from 2003 to 2019
(Journal article, 2023) -
The Deep Arctic Ocean and Fram Strait in CMIP6 Models
(Journal article, 2023)Arctic sea ice loss has become a symbol of ongoing climate change, yet climate models still struggle to reproduce it accurately, let alone predict it. A reason for this is the increasingly clear role of the ocean, especially ... -
The Southern Ocean Freshwater Input from Antarctica (SOFIA) Initiative: scientific objectives and experimental design
(Journal article, 2023)As the climate warms, the grounded ice sheet and floating ice shelves surrounding Antarctica are melting and releasing additional freshwater into the Southern Ocean. Nonetheless, almost all existing coupled climate models ... -
Divergence in Climate Model Projections of Future Arctic Atlantification
(Journal article, 2022)The Arctic Ocean is strongly stratified by salinity in the uppermost layers. This stratification is a key attribute of the region as it acts as an effective barrier for the vertical exchanges of Atlantic Water heat, ... -
An improved radiative forcing scheme for better representation of Arctic under-ice blooms
(Journal article, 2022)In the present study, a newly designed radiative forcing scheme, i.e., impulsive radiative forcing scheme (IRFS), is applied in the one-dimensional Regional Ocean Modeling System-Carbon Silicate Nitrate Ecosystem (ROMS-CoSiNE) ... -
On the turbulent heat fluxes: A comparison among satellite-based estimates, atmospheric reanalyses, and in-situ observations during the winter climate over Arctic sea ice
(Journal article, 2023)En sammenligning mellom satellittbaserte estimater, atmosfæriske reanalyser, og in situ observasjoner under vinterklimaet over arktisk sjøis I Polhavet og tilgrensende områder finnes det svært få direkte målinger av fysiske ... -
Regime shift in Arctic Ocean sea ice thickness
(Journal article, 2023)Manifestations of climate change are often shown as gradual changes in physical or biogeochemical properties1. Components of the climate system, however, can show stepwise shifts from one regime to another, as a nonlinear ... -
Seabird-Transported Contaminants Are Reflected in the Arctic Tundra, But Not in Its Soil-Dwelling Springtails (Collembola)
(Journal article, 2019-10)Arctic-breeding seabirds contain high levels of many anthropogenic contaminants, which they deposit through guano to the tundra near their colonies. Nutrient-rich soil in vicinity to seabird colonies are favorable habitats ... -
First assessment of pollutant exposure in two balaenopterid whale populations sampled in the Svalbard Archipelago, Norway
(Peer reviewed; Journal article, 2020-02)Pollutant concentrations are poorly known for the largest animals on Earth, blue whales Balaenoptera musculus and fin whales Balaenoptera physalus. In this study, concentrations of persistent organic pollutants (POPs) were ... -
First videos of endemic Zanzibar servaline genet Genetta servalina archeri, African palm civet Nandinia binotata (Mammalia: Carnivora: Viverridae) and other small carnivores on Unguja Island, Tanzania
(Peer reviewed; Journal article, 2019)The faunal diversity of the densely populated island of Unguja, Zanzibar archipelago, Tanzania, includes several endemic mammals. Camera-trapping in Jozani-Chwaka Bay National Park and Kiwengwa–Pongwe Forest Reserve in ... -
Circumpolar status of Arctic ptarmigan: population dynamics and trends
(Peer reviewed; Journal article, 2019)Rock ptarmigan (Lagopus muta) and willow ptarmigan (L. lagopus) are Arctic birds with a circumpolar distribution but there is limited knowledge about their status and trends across their circumpolar distribution. Here, we ... -
Black carbon in the atmosphere and snow, from pre-industrial times until present
