Can structural enrichment reduce predation mortality and increase recaptures of hatchery‐reared Atlantic salmon Salmo salar L. fry released into the wild?
(Peer reviewed; Journal article, 2019)Captive‐reared fish often have poor survival in the wild and may fail to boost threatened populations. Enrichment during the nursery period can in some circumstances generate a broader behavioural repertoire than conventional ... -
Can we use ice sheet reconstructions to constrain meltwater for deglacial simulations?
(Journal article, 2012)Freshwater pulses from melting ice sheets are thought to be important for driving deglacial climate variability. This study investigates challenges in simulating and understanding deglacial climate evolution within this ... -
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 ... -
Carbonate compensation depth drives abyssal biogeography in the northeast Pacific
(Peer reviewed; Journal article, 2023)Abyssal seafloor communities cover more than 60% of Earth’s surface. Despite their great size, abyssal plains extend across modest environmental gradients compared to other marine ecosystems. However, little is known about ... -
Causal oceanic feedbacks onto the winter NAO
(Peer reviewed; Journal article, 2024)Of the climate variability patterns that influence the weather in the North Atlantic region in winter, the North Atlantic Oscillation (NAO) is the most dominant. The effects of the NAO span from cold air outbreaks to ... -
Causes of bias and uncertainty in fracture network analysis
(Peer reviewed; Journal article, 2019)Fault and fracture networks are analysed to determine the deformation history and to help with such applications as engineering geology and fluidflow modelling. These analyses rely on quantifying such factors as length, ... -
Centennial relationships between ocean temperature and Atlantic puffin production reveal shifting decennial trends
(Peer reviewed; Journal article, 2021)The current warming of the oceans has been shown to have detrimental effects for a number of species. An understanding of the underlying mechanisms may be hampered by the non-linearity and non-stationarity of the relationships ... -
Challenges for transgene detection in landraces and wild relatives: learning from 15 years of debate over GM maize in Mexico
(Peer reviewed; Journal article, 2018)Maize is one of the world’s five staple cereals and its traditional varieties constitute a global resource critical to future agricultural development. Fifteen years ago, claims that transgenes had spread into traditional ... -
Changes in Onset of Vegetation Growth on Svalbard, 2000–2020
(Journal article; Peer reviewed, 2022)The global temperature is increasing, and this is affecting the vegetation phenology in many parts of the world. The most prominent changes occur at northern latitudes such as our study area, which is Svalbard, located ... -
Characteristics of precipitation extremes over the Nordic region: added value of convection-permitting modeling
(Peer reviewed; Journal article, 2022)It is well established that using kilometer scale grid resolution for simulations of weather systems in weather and climate models enhances their realism. This study explores heavy- and extreme-precipitation characteristics ... -
Characteristics of Surface “Melt Potential” over Antarctic Ice Shelves based on Regional Atmospheric Model Simulations of Summer Air Temperature Extremes from 1979/80 to 2018/19
(Peer reviewed; Journal article, 2023)We calculate a regional surface “melt potential” index (MPI) over Antarctic ice shelves that describes the frequency (MPI-freq; %) and intensity (MPI-int; K) of daily maximum summer temperatures exceeding a melt threshold ... -
Characterization of a novel cold-adapted intracellular serine protease from the extremophile Planococcus halocryophilus Or1
(Peer reviewed; Journal article, 2023)The enzymes of microorganisms that live in cold environments must be able to function at ambient temperatures. Cold-adapted enzymes generally have less ordered structures that convey a higher catalytic rate, but at the ... -
Characterizing Reef Net Metabolism Via the Diel Co-Variation of pH and Dissolved Oxygen From High Resolution in Situ Sensors
(Peer reviewed; Journal article, 2023)Coral reefs are subject to degradation by multiple environmental stressors which are predicted to intensify. Stress can alter ecosystem composition, with shifts from hard coral to macroalgae dominated reefs often accompanied ... -
Checklist of newly-vouchered annelid taxa from the Clarion-Clipperton Zone, central Pacific Ocean, based on morphology and genetic delimitation
(Journal article; Peer reviewed, 2023)We present a checklist of annelids from recent United Kingdom Seabed Resources (UKSR) expeditions (Abyssal Baseline - ABYSSLINE project) to the eastern abyssal Pacific Clarion-Clipperton Zone (CCZ) polymetallic nodule ... -
Circulation responses to surface heating and implications for polar amplification
(Journal article; Peer reviewed, 2024)A seminal study by Hoskins and Karoly (1981) explored the atmospheric circulation response to tropospheric heating perturbations at low latitudes and midlatitudes. Here we revisit and extend their study by investigating ... -
Climate change information over Fenno-Scandinavia produced with a convection-permitting climate model
(Peer reviewed; Journal article, 2022)This paper presents results from high-resolution climate change simulations that permit convection and resolve mesoscale orography at 3-km grid spacing over Fenno-Scandinavia using the HARMONIE-Climate (HCLIM) model. Two ... -
Climate Evolution Through the Onset and Intensification of Northern Hemisphere Glaciation
(Peer reviewed; Journal article, 2023)The Pliocene Epoch (∼5.3–2.6 million years ago, Ma) was characterized by a warmer than present climate with smaller Northern Hemisphere ice sheets, and offers an example of a climate system in long-term equilibrium with ... -
Climate Scenarios for Switzerland CH2018 – Approach and Implications
(Peer reviewed; Journal article, 2022)To make sound decisions in the face of climate change, government agencies, policymakers and private stakeholders require suitable climate information on local to regional scales. In Switzerland, the development of climate ... -
Climate tipping point interactions and cascades: A review
(Journal article; Peer reviewed, 2024)Climate tipping elements are large-scale subsystems of the Earth that may transgress critical thresholds (tipping points) under ongoing global warming, with substantial impacts on the biosphere and human societies. Frequently ... -
Climate transition at the Eocene-Oligocene influenced by bathymetric changes to the Atlantic-Arctic oceanic gateways
(Peer reviewed; Journal article, 2022)The Eocene–Oligocene Transition (∼33.9 Ma) marks the largest step transformation within the Cenozoic cooling trend and is characterized by a sudden growth of the Antarctic ice sheets, cooling of the interior ocean, and the ...
