Atlantic salmon Salmo salar and ballan wrasse Labrus bergylta display different susceptibility to clonal strains of Paramoeba perurans
(Journal article; Peer reviewed, 2020)Amoebic gill disease (AGD), caused by the marine amoeba Paramoeba perurans, is an important disease of farmed Atlantic salmon Salmo salar L. in Norway. The use of wrasse as cleaner fish in salmon net pens raises questions ... -
Atlantic thermohaline changes and its implications on the carbon cycle during the Last Interglacial
(Doctoral thesis, 2020-06-16)Large and abrupt changes in the Earth’s climate have been recorded in marine records and Greenland ice cores and mostly characterize the last glacial period. These sudden transitions of climate, occurring within a few ... -
Atlantic Water Boundary Current Along the Southern Yermak Plateau, Arctic Ocean
(Journal article; Peer reviewed, 2023)The major ocean current that carries heat into the Arctic Ocean splits into three main branches of Atlantic Water (AW) and recirculations when it encounters the Yermak Plateau (YP) located north of Svalbard. While the ... -
Atlantic Water Circulation and Properties Northwest of Svalbard During Anomalous Southerly Winds
(Journal article; Peer reviewed, 2022)Atlantic Water (AW), the main source of heat and salt for the Arctic Ocean, undergoes large transformations (cooling and freshening) north of Svalbard as it flows near the surface above the Yermak Plateau (YP). In September ... -
The Atlantic Water flow along the Vøring Plateau: Detecting frontal structures in oceanic station time series
(Journal article, 2007-01-13)The topographic steering of the baroclinic western branch of the Norwegian Atlantic Current (NwAC) determines the extent of Atlantic Water and location of the Arctic Front in the Nordic Seas. In this paper the geographical ... -
Atlantic Water in the Arctic Ocean - Mechanisms and Impacts
(Doctoral thesis, 2021-08-19)The Arctic Ocean plays a fundamental role in regulating Earth’s climate, and a changing Arctic will affect climate, weather, and life everywhere on the planet. Understanding the fundamental dynamics and mechanisms driving ... -
Atlantic water inflow into the Arctic Ocean: studies of pathways, transport and mixing processes using observations from ships and autonomous underwater vehicles
(Doctoral thesis, 2024-01-23)Nordishavet spiller en viktig rolle i det globale klimasystemet. Produksjon av kaldt vann med høy tetthet, samt frysing av sjøis i Arktis, bidrar til å drive den Atlantiske meridionale omveltningssirkulasjonen og kan påvirke ... -
Atlantic Water Inflow Through the Yermak Pass Branch: Evolution Since 2007
(Journal article; Peer reviewed, 2022)Thirty-four months (2017–2020) of mooring data were recently obtained at 80.6°N, 7.26°E in the main branch of Atlantic Water inflow to the Arctic, the Yermak Pass Branch. The Yermak Pass Branch was sampled at that same ... -
Atlantic Water Pathways Along the North-Western Svalbard Shelf Mapped Using Vessel-Mounted Current Profilers
(Peer reviewed; Journal article, 2019-03)A large amount of warm Atlantic water (AW) enters the Arctic as a boundary current through Fram Strait (West Spitsbergen Current [WSC]) and is the major oceanic heat source to the Arctic Ocean. Along the north‐western ... -
Atlantic water properties, transport and heat loss from mooring observations north of Svalbard
(Journal article; Peer reviewed, 2022)The Atlantic Water inflow to the Arctic Ocean is transformed and modified in the area north of Svalbard, which influences the Arctic Ocean heat and salt budget. Year-round observations are relatively sparse in this region ... -
Atlantic water transformation along its poleward pathway across the Nordic Seas
(Peer reviewed; Journal article, 2018-08-23)The warm and salty Atlantic Water is substantially modified along its poleward transit across the Nordic Seas, where it reaches deeper isopycnals. In particular, the Lofoten Basin, exposed to intense air‐sea interactions, ... -
An Atlantic-driven rapid circulation change in the North Pacific Ocean during the late 1990s
(Peer reviewed; Journal article, 2019-10-08)Interbasin interactions have been increasingly emphasized in recent years due to their roles in shaping climate trends and the global warming hiatus in the northern hemisphere. The profound influence from the North Atlantic ... -
Atlantic-Origin Overflow Water in the East Greenland Current
(Peer reviewed; Journal article, 2019)Dense water masses transported southward along the east coast of Greenland in the East Greenland Current (EGC) form the largest contribution to the Denmark Strait Overflow. When exiting Denmark Strait these dense water ... -
ATLAS b-jet identification performance and efficiency measurement with tt¯ events in pp collisions at √s=13 TeV
(Peer reviewed; Journal article, 2019)The algorithms used by the ATLAS Collaboration during Run 2 of the Large Hadron Collider to identify jets containing b-hadrons are presented. The performance of the algorithms is evaluated in the simulation and the efficiency ... -
