230Th Normalization: New Insights on an Essential Tool for Quantifying Sedimentary Fluxes in the Modern and Quaternary Ocean
(Journal article; Peer reviewed, 2020-01)230Th normalization is a valuable paleoceanographic tool for reconstructing high‐resolution sediment fluxes during the late Pleistocene (last ~500,000 years). As its application has expanded to ever more diverse marine ... -
The 3 km Norwegian reanalysis (NORA3) – a validation of offshore wind resources in the North Sea and the Norwegian Sea
(Journal article; Peer reviewed, 2021)We validate a new high-resolution (3 km) numerical mesoscale weather simulation for offshore wind power purposes for the time period 2004–2016 for the North Sea and the Norwegian Sea. The 3 km Norwegian reanalysis (NORA3) ... -
A 4.5 Year‐Long Record of Svalbard Water Vapor Isotopic Composition Documents Winter Air Mass Origin
(Journal article; Peer reviewed, 2020)From May 2014 to September 2018, a laser spectrometer analyzer provided a 4.5 years continuous record of water vapor isotopic composition at Ny-Ålesund (8 m above sea level, a.s.l.), Svalbard. It corresponds to the longest ... -
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 ... -
Advances in understanding and parameterization of small-scalephysical processes in the marine Arctic climate system: a review
(Peer reviewed; Journal article, 2014-09-10)The Arctic climate system includes numerous highly interactive small-scale physical processes in the atmosphere, sea ice, and ocean. During and since the International Polar Year 2007–2009, significant advances have been ... -
Aerodynamic study of a suspension bridge deck by CFD simulations, wind tunnel tests and full-scale observations
(Journal article; Peer reviewed, 2021)Assessing the aerodynamic characteristics of long-span bridges is fundamental for their design. Depending on the terrain complexity and local wind conditions, episodes of large angles of attack (AoA) of 15° may be observed. ... -
Airborne observations of the Eyjafjalla volcano ash cloud over Europe during air space closure in April and May 2010
(Peer reviewed; Journal article, 2011-03-11)Airborne lidar and in-situ measurements of aerosols and trace gases were performed in volcanic ash plumes over Europe between Southern Germany and Iceland with the Falcon aircraft during the eruption period of the Eyjafjalla ... -
Aircraft-based observations and high-resolution simulations of an Icelandic dust storm
(Peer reviewed; Journal article, 2012-11-16)The first aircraft-based observations of an Icelandic dust storm are presented. The measurements were carried out over the ocean near Iceland's south coast in February 2007. This dust event occurred in conjunction with an ... -
Along‐stream, seasonal, and interannual variability of the North Icelandic Irminger Current and East Icelandic Current around Iceland
(Journal article; Peer reviewed, 2020)Data from repeat hydrographic surveys over the 25-year period 1993 to 2017, together with satellite altimetry data, are used to quantify the temporal and spatial variability of the North Icelandic Irminger Current (NIIC), ... -
Amplification of synoptic to annual variability of West African summer monsoon rainfall under global warming
(Journal article; Peer reviewed, 2020)Increased knowledge of future changes in rainfall variability is needed to reduce vulnerability to potential impacts of global warming, especially in highly vulnerable regions like West Africa. While changes in mean and ... -
