A 30-year probability map for oil spill trajectories in the barents sea to assess potential environmental and socio-economic threats
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-24)Increasing exploration and exploitation activity in the Arctic Ocean has intensified maritime traffic in the Barents Sea. Due to the sparse population and insufficient oil spill response infrastructure on the extensive Barents Sea shoreline, it is necessary to address the possibility of offshore accidents and study hazards to the local environment and its resources. Simulations of surface oil ... -
Assessment of possible adverse consequences for biodiversity when planting vascular plants outside their natural range in Norway -(VKM)
(Research report; Forskningsrapport, 2021-06-25)We sow or plant vascular plant species on a large scale in revegetation and restoration projects in Norway today. Some of the species used are already found in Norway, but many of the species, subspecies or populations used though native are not local, that is, they are <i>regionally alien</i>. A regionally alien species is a species that is native to Norway (has been in Norway since 1800) somewhere ... -
Assessment of risk and risk-reducing measures related to the introduction and dispersal of the invasive alien carpet tunicate Didemnum vexillum in Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-17)Didemnum vexillum is colonial sea squirt, a marine species which originates from the northwest Pacific; it was first recorded in Norway in November 2020. Didemnum vexillum is an alien species, meaning that it is a species that has been transferred from its original region to other regions of the world through human activity, and it had not previously been recorded in Norwegian waters. The species ... -
Assessment of the risk to Norwegian biodiversity from import and keeping of crustaceans in freshwater aquaria. Scientific Opinion of the Panel on Alien Organisms and Trade in Endangered Species of the Norwegian Scientific Committee for Food and Environment
(Research report; Forskningsrapport, 2021)The Norwegian Scientific Committee for Food and Environment (VKM) was requested by the Norwegian Environment Agency to assess the risk of negative impacts to biodiversity in Norway resulting from import of crustacean decapods for keeping in freshwater aquariums.<p> <p>VKM was asked to 1) list species of crayfish, crabs and shrimps that are currently kept in freshwater aquaria in Norway, and ... -
A dataset of direct observations of sea ice drift and waves in ice
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-03)Variability in sea ice conditions, combined with strong couplings to the atmosphere and the ocean, lead to a broad range of complex sea ice dynamics. More in-situ measurements are needed to better identify the phenomena and mechanisms that govern sea ice growth, drift, and breakup. To this end, we have gathered a dataset of in-situ observations of sea ice drift and waves in ice. A total of 15 ... -
Estimating a mean transport velocity in the marginal ice zone using ice-ocean prediction systems
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-01)Understanding the transport of objects and material in the marginal ice zone (MIZ) is critical for human operations in polar regions. This can be the transport of pollutants, such as spilled oil, or the transport of objects, such as drifting ships and search and rescue operations. For emergency response, the use of environmental prediction systems are required which predict ice and ocean parameters ... -
Impacts of offshore oil spill accidents on island bird communities: A test run study around Orkney and Svalbard archipelagos
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-15)The sea area around the Orkney archipelago, Scotland is subjected to substantial maritime shipping activities. By contract, the Svalbard archipelago, Norway currently has a rather low marine traffic profile. Future projections, however, indicate that the Trans-Arctic route might change the whole transportation picture and Svalbard may be at the centre of maritime activities. Both archipelagos ... -
Integrated analysis of multi-sensor datasets and oil drift simulations - a free floating oil experiment in the open ocean
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-20)A free‐floating oil spill experiment (two oil types) in the open ocean is described, and the results from slick characterization through integrated analysis of drift simulations with remote sensing and in situ data are discussed. We compare oil drift simulations (OpenOil), applying various configurations of wind, wave, and current information, with the observed slick positions and shape. We describe ... -

The One Ocean Expedition: Science and Sailing for the Ocean We Want
(Research report; Forskningsrapport, 2023-08-24)The One Ocean Expedition (OOE) was a 20-month long circumnavigation of the globe by the Norwegian sail training vessel Statsraad Lehmkuhl, and a recognised part of the UN decade of Ocean Science for Sustainable Development. The ship was equipped with modern instrumentation to collect high-quality data on ocean physics, chemistry, and biology. Many of the data series were available in near real time ... -
OpenMetBuoy-v2021: An Easy-to-Build, Affordable, Customizable, Open-Source Instrument for Oceanographic Measurements of Drift and Waves in Sea Ice and the Open Ocean
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-26)There is a wide consensus within the polar science, meteorology, and oceanography communities that more in situ observations of the ocean, atmosphere, and sea ice are required to further improve operational forecasting model skills. Traditionally, the volume of such measurements has been limited by the high cost of commercially available instruments. An increasingly attractive solution to this ... -
Quantitative assessment of two oil-in-ice surface drift algorithms
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-04)The ongoing reduction in extent and thickness of sea ice in the Arctic might result in an increase of oil spill risk due to the expansion of shipping activity and oil exploration shift towards higher latitudes. This work assessed the response of two oil-in-ice surface drift models implemented in an open-source Lagrangian framework. By considering two numerical modeling experiments, our main finding ... -
Status and trade assessment of parrots listed in CITES Appendix I. Scientific Opinion of the Panel on Alien Organisms and trade in endangered species (CITES)
(Research report; Forskningsrapport, 2020-12-18)Parrots are one of the most species-rich groups of birds of which the majority inhabits tropical and subtropical forests. Nearly one-third of parrots are threatened with extinction (IUCN categories CR, EN or VU) and more than half of the world’s parrot species are assumed to be decreasing in numbers. Parrots are popular pets on all continents, mainly due to their colourful feathers, their capacity ...
