Evolving the global ocean observing system for research and application services through international coordination
(Peer reviewed; Journal article, 2019-08-06)Climate change and variability are major societal challenges, and the ocean is an integral part of this complex and variable system. Key to the understanding of the ocean’s role in the Earth’s climate system is the study ... -
Exceptionally Warm and Prolonged Flow of Warm Deep Water Toward the Filchner‐Ronne Ice Shelf in 2017
(Journal article; Peer reviewed, 2020)The Filchner-Ronne Ice Shelf, fringing the southern Weddell Sea, is Antarctica's second largest ice shelf. At present, basal melt rates are low due to active dense water formation; however, model projections suggest a ... -
Exchange of water masses between the southern Weddell Sea continental shelf and the deep ocean
(Doctoral thesis, 2018-06-13)The exchange of water masses between the shallow Weddell Sea continental shelf and the deep ocean is of climatic importance. Firstly, on-shelf transport of warm oceanic water masses, contributes to basal melting of ice ... -
Experimental characterization of the marine atmospheric boundary layer in the Havsul area, Norway
(Peer reviewed; Journal article, 2013)Offshore wind energy applications depend strongly on an improved knowledge of the physical processes taking place in marine atmospheric boundary layer (MABL). In particular the better understanding of the complex interactions ... -
Experimental investigation of the stable water isotope distribution in an Alpine lake environment (L-WAIVE)
(Journal article; Peer reviewed, 2021)In order to gain understanding on the vertical structure of atmospheric water vapour above mountain lakes and to assess its link with the isotopic composition of the lake water and with small-scale dynamics (i.e. valley ... -
Experimental methods to study the process of snow-ice formation induced by saltwater rise
(Master thesis, 2018-11-09)The Arctic region is experiencing a change from thick multiyear to much younger and thinner sea ice. In many places, increasing precipitation is leading to higher snow loads on young sea ice. Hence seawater can infiltrate ... -
An experimental study on the effects of winglets on the tip vortex interaction in the near wake of a model wind turbine
(Journal article; Peer reviewed, 2020)An experimental study of the near wake up to four rotor diameters behind a model wind turbine rotor with two different wing tip configurations is performed. A straight-cut wing tip and a downstream-facing winglet shape are ... -
Exploring Arctic-midlatitude teleconnections using observations and numerical models
(Doctoral thesis, 2021-05-27)The Arctic is warming at a much faster rate than the rest of the globe, with large declines in sea ice, snow cover and permafrost over the last decades. These profound changes have been proposed to influence the midlatitude ... -
Exploring the coupled ocean and atmosphere system with a data science approach applied to observations from the Antarctic Circumnavigation Expedition
(Journal article; Peer reviewed, 2021)The Southern Ocean is a critical component of Earth's climate system, but its remoteness makes it challenging to develop a holistic understanding of its processes from the small scale to the large scale. As a result, our ... -
Exploring the potential of the RPA system SUMO for multipurpose boundary-layer missions during the BLLAST campaign
(Peer reviewed; Journal article, 2016-06-24)In June and July 2011 the RPAS (Remotely Piloted Aircraft System) SUMO (Small Unmanned Meteorological Observer) performed a total number of 299 scientific flights during the BLLAST (Boundary Layer Late Afternoon and Sunset ... -
Export of calcium carbonate corrosive waters from the East Siberian Sea
(Peer reviewed; Journal article, 2017-04-05)The Siberian shelf seas are areas of extensive biogeochemical transformation of organic matter, both of marine and terrestrial origin. This in combination with brine production from sea ice formation results in a cold ... -
Export of ice sheet meltwater from Upernavik fjord, West Greenland
(Journal article; Peer reviewed, 2022)Meltwater from Greenland is an important freshwater source for the North Atlantic Ocean, released into the ocean at the head of fjords in the form of runoff, submarine melt, and icebergs. The meltwater release gives rise ... -
Extracting statistical parameters of extreme precipitation from a NWP model
(Peer reviewed; Journal article, 2009-11-25)Precipitation simulations on an 8×8 km grid using the PSU/NCAR Mesoscale Model MM5 are used to estimate the M5 and Ci statistical parameters in order to support the M5 map used for flood estimates by Icelandic engineers. ... -
The extreme Arctic warm anomaly in November 2020
(Journal article; Peer reviewed, 2022)In November 2020, the eastern Arctic experienced an extensive extreme warm anomaly (i.e., the second strongest case since 1979), which was followed by extreme cold conditions over East Asia in early winter. The observed ... -
Extreme precipitation in Central Norway. A case and climate study
(Master thesis, 2010-06-01)An extreme precipitation event occurred over Central Norway at the end of January to the beginning of February 2006. The heavy precipitation in addition to high temperatures lead to snow melt and increased run-off, which ... -
Extreme Precipitation in Nepal. Trends and Key Processes
(Doctoral thesis, 2018-03-21)Nepal is located at the rim of the Himalayas and houses the highest mountains of the world. Owing to the complex topography and a seasonal monsoon climate, Nepal experiences precipitation events of considerable intensity. ... -
Extreme winds in the Nordic Seas : polar lows and Arctic fronts in a changing climate

Extremes and Trends in Wave Climate. A regional and global study
(Doctoral thesis, 2015-01-16)Wind generated surface waves represent a critical factor for offshore constructions and coastal development, and are highly relevant in scientific questions related to climate and weather. The sea state can be described ... -
Facilitating microplastic quantification through the introduction of a cellulose dissolution step prior to oxidation: Proof-of-concept and demonstration using diverse samples from the Inner Oslofjord, Norway
(Journal article; Peer reviewed, 2020)Identifying and quantifying microplastic in marine samples can be facilitated by removing natural organic matter (NOM). Cellulosic material, like chitin, however, are a type of NOM that is resistant to chemical digestion, ... -
