Global Ocean Sediment Composition and Burial Flux in the Deep Sea
(Journal article; Peer reviewed, 2021)Quantitative knowledge about the burial of sedimentary components at the seafloor has wide-ranging implications in ocean science, from global climate to continental weathering. The use of 230Th-normalized fluxes reduces ... -
Global ocean wave fields show consistent regional trends between 1980 and 2014 in a multi-product ensemble
(Journal article; Peer reviewed, 2022)Historical trends in the direction and magnitude of ocean surface wave height, period, or direction are debated due to diverse data, time-periods, or methodologies. Using a consistent community-driven ensemble of global ... -
Global Surface Ocean Acidification Indicators From 1750 to 2100
(Journal article; Peer reviewed, 2023)Accurately predicting future ocean acidification (OA) conditions is crucial for advancing OA research at regional and global scales, and guiding society's mitigation and adaptation efforts. This study presents a new ... -
Global variability in seawater Mg:Ca and Sr:Ca ratios in the modern ocean
(Journal article; Peer reviewed, 2020)Seawater Mg:Ca and Sr:Ca ratios are biogeochemical parameters reflecting the Earth–ocean–atmosphere dynamic exchange of elements. The ratios’ dependence on the environment and organisms' biology facilitates their application ... -
Global wind speed and wave height extremes derived from long-duration satellite records
(Peer reviewed; Journal article, 2019)The application of extreme-value analysis to long-duration (30 year) global altimeter and radiometer datasets is considered. In contrast to previous extreme-value analyses of satellite data, the dataset is sufficiently ... -
GLODAPv2.2022: the latest version of the global interior ocean biogeochemical data product
(Journal article; Peer reviewed, 2022)The Global Ocean Data Analysis Project (GLODAP) is a synthesis effort providing regular compilations of surface-to-bottom ocean biogeochemical bottle data, with an emphasis on seawater inorganic carbon chemistry and related ... -
The greater Agulhas Current system: an integrated study of its mesoscale variability
(Journal of Operational Oceanography, Journal article, 2008-02)For the purpose of developing an operational oceanography system for the greater Agulhas Current regime, a high resolution Hybrid Coordinate Ocean Model (HYCOM) has been set in a nested configuration. The intense and complex ... -
Greenland climate simulations show high Eemian surface melt which could explain reduced total air content in ice cores
(Journal article; Peer reviewed, 2021)This study presents simulations of Greenland surface melt for the Eemian interglacial period (∼130 000 to 115 000 years ago) derived from regional climate simulations with a coupled surface energy balance model. Surface ... -
Greenland surface air temperature changes from 1981 to 2019 and implications for ice-sheet melt and mass-balance change
(Journal article; Peer reviewed, 2020)We provide an updated analysis of instrumental Greenland monthly temperature data to 2019, focusing mainly on coastal stations but also analysing ice‐sheet records from Swiss Camp and Summit. Significant summer (winter) ... -
Greenland-Scotland overflow studied by hydro-chemical multivariate analysis
(Peer reviewed; Journal article, 2003-01)Hydrographic, nutrient and halocarbon tracer data collected in July-August 1994 in the Norwegian Sea, the Faroe Bank Channel (FBC), the Iceland and Irminger Basins and the Iceland Sea are resented. Special attention was ... -
Grounding Performance under Lightning Surges in High Voltage Substations
(Master thesis, 2018-06-16)To achieve electromagnetic compatibility (EMC) and sufficient protection against lighting transients in the power transmission system, understanding of the grounding system transient behavior becomes crucial when deviating ... -
Groundwater fluctuations during a debris flow event in western Norway - Triggered by rain and snowmelt
(Journal article; Peer reviewed, 2021)Pore pressure is crucial in triggering debris slides and flows. Here we present measurements of groundwater pore pressure and temperature recorded by a piezometer 1.6 m below the surface on a slope susceptible to debris ... -
Growing Ice in a Tank: Young Sea Ice Evolution and Turbulence in the Under Ice Boundary Layer
(Master thesis, 2011-11-14)Thin sea ice and its modifications of the oceanic boundary layer are important in the context of the recent retreat of the Arctic sea ice cover. To study turbulence in the under ice boundary layer during thin sea ice growth, ... -
Has a warm North Atlantic contributed to recent European cold winters?
(Peer reviewed; Journal article, 2014-06-02)The rise of global surface temperature waned during the last decade, despite increasing greenhouse gas concentrations. The temperature changes were most pronounced over northern hemisphere land masses during winter (Cohen ... -

Heterogeneity of impacts of high CO2 on the North Western European shelf
(Peer reviewed; Journal article, 2014-02-03)The increase in atmospheric CO2 is a dual threat to the marine environment: from one side it drives climate change, leading to modifications in water temperature, circulation patterns and stratification intensity; on the ... -
High northern latitude surface air temperature: comparison of existing data and creation of a new gridded data set 1900–2000
(Peer reviewed; Journal article, 2008-03)Detection, attribution and understanding of temperature changes in the high northern latitudes depend on constraining uncertainties and resolving apparent discrepancies in observational data sets. We quantitatively compare ... -
High resolution sea ice monitoring using space borne Synthetic Aperture Radar
