Acidification of the Nordic Seas
(Journal article; Peer reviewed, 2022)Due to low calcium carbonate saturation states, and winter mixing that brings anthropogenic carbon to the deep ocean, the Nordic Seas and their cold-water corals are vulnerable to ocean acidification. Here, we present a ... -
Arctic Ocean acidification over the 21st century co-driven by anthropogenic carbon increases and freshening in the CMIP6 model ensemble
(Journal article; Peer reviewed, 2021)The uptake of anthropogenic carbon (Cant) by the ocean leads to ocean acidification, causing the reduction of pH and the saturation states of aragonite (Ωarag) and calcite (Ωcalc). The Arctic Ocean is particularly vulnerable ... -
Carbon cycle feedbacks in an idealized simulation and a scenario simulation of negative emissions in CMIP6 Earth system models
(Peer reviewed; Journal article, 2024)Limiting global warming to well below 2 ∘C by the end of the century is an ambitious target that requires immediate and unprecedented emission reductions. In the absence of sufficient near-term mitigation, this target will ... -
Deep-sea sponge grounds as nutrient sinks: Denitrification is common in boreo-Arctic sponges
(Peer reviewed; Journal article, 2020)Sponges are commonly known as general nutrient providers for the marine ecosystem, recycling organic matter into various forms of bioavailable nutrients such as ammonium and nitrate. In this study we challenge this view. ... -
Evaluation of ocean dimethylsulfide concentration and emission in CMIP6 models
(Peer reviewed; Journal article, 2021)Characteristics and trends of surface ocean dimethylsulfide (DMS) concentrations and fluxes into the atmosphere of four Earth system models (ESMs: CNRM-ESM2-1, MIROC-ES2L, NorESM2-LM, and UKESM1-0-LL) are analysed over the ... -
Net primary production annual maxima in the North Atlantic projected to shift in the 21st century
(Peer reviewed; Journal article, 2024)Shifts in the day of peak net primary production (NPP) were detected in different biogeochemical provinces of the North Atlantic (25–65° N). Most provinces displayed a shift toward earlier peak NPP, with the largest change ... -
The northern European shelf as an increasing net sink for CO2
(Peer reviewed; Journal article, 2021)We developed a simple method to refine existing open-ocean maps and extend them towards different coastal seas. Using a multi-linear regression we produced monthly maps of surface ocean fCO2 in the northern European coastal ... -
Plant phenology evaluation of CRESCENDO land surface models-Part 1: Start and end of the growing season
(Peer reviewed; Journal article, 2021)Plant phenology plays a fundamental role in land–atmosphere interactions, and its variability and variations are an indicator of climate and environmental changes. For this reason, current land surface models include ... -
The representation of alkalinity and the carbonate pump from CMIP5 to CMIP6 Earth system models and implications for the carbon cycle
(Peer reviewed; Journal article, 2023)Ocean alkalinity is critical to the uptake of atmospheric carbon in surface waters and provides buffering capacity towards the associated acidification. However, unlike dissolved inorganic carbon (DIC), alkalinity is not ... -
Reviews and syntheses: Remotely sensed optical time series for monitoring vegetation productivity
(Peer reviewed; Journal article, 2024)Vegetation productivity is a critical indicator of global ecosystem health and is impacted by human activities and climate change. A wide range of optical sensing platforms, from ground-based to airborne and satellite, ...
