Distinct polymer-dependent sorption of persistent pollutants associated with Atlantic salmon farming to microplastics
(Peer reviewed; Journal article, 2022)Interactions of microplastics and persistent organic pollutants (POPs) associated with Atlantic salmon farming were studied to assess the potential role of microplastics in relation to the environmental impact of aquaculture. ... -
Distinction and relatedness – Taxonomic and genetic studies reveal a new species group of goatfishes (Upeneus; Mullidae)
(Journal article; Peer reviewed, 2015-10-07)Phenotypic and genetic differentiation among goatfish species of the genus Upeneus which had been formerly included in the so-called ‘vittatus group’ were examined using a comprehensive alpha-taxonomic and barcoding approach. ... -
Distribution and Abundance of the Blue Whale (Balaenoptera musculus indica) off Sri Lanka during the Southwest Monsoon 2018
(Peer reviewed; Journal article, 2022)Blue whales Balaenoptera musculus are the most abundant and widely distributed cetacean species in Sri Lankan waters. A vessel-based opportunistic line transect survey focusing on marine mammals was conducted in Sri Lankan ... -
Distribution and Abundances of Planktic Foraminifera and Shelled Pteropods During the Polar Night in the Sea-Ice Covered Northern Barents Sea
(Peer reviewed; Journal article, 2021)Planktic foraminfera and shelled pteropods are important calcifying groups of zooplankton in all oceans. Their calcium carbonate shells are sensitive to changes in ocean carbonate chemistry predisposing them as an important ... -
Distribution and biomass estimation of Antarctic krill (Euphausia superba) off the South Orkney Islands during 2011-2020
(Peer reviewed; Journal article, 2023)Antarctic krill is a key species in the Southern Ocean and subject to the most extensive fishery in the Antarctic. The Norwegian Institute of Marine Research has conducted acoustic-trawl monitoring of krill off the South ... -
Distribution and density of goldsinny wrasse (Ctenolabrus rupestris) (Labridae) in the Risør and Arendal areas along the Norwegian Skagerrak coast
(Journal article; Peer reviewed, 2002-03)Samples of fish were collected in the Arendal and Risør areas on the Norwegian Skagerrak coast during the period 1986 to 1990 using a beach seine at 36 different locations. In the Risør area, 131 out of 254 hauls yielded ... -
Distribution and diversity of fish species along the Sudanese Red Sea coast based on three combined trap and gillnet surveys
(Peer reviewed; Journal article, 2021)On the western shore of the semi-enclosed coral-reef rich Red Sea, the 850 km coastline of the Red Sea State of the Republic of Sudan provides livelihoods to artisanal fishers, but the present state of the living natural ... -
Distribution and diversity of mesopelagic fauna on seamounts of the Madeira-Tore complex (Northeastern Atlantic)
(Peer reviewed; Journal article, 2020)Mesopelagic organisms play an important role in the vertical carbon flux through diel vertical migrations. The mesopelagic fauna of three NE Atlantic seamounts (Gorringe Bank, Josephine and Seine) and surrounding oceanic ... -
