Lateral Heat Transport in the Lofoten Basin: Near-Surface Pathways and Subsurface Exchange
Dugstad, Johannes Sandanger; Fer, Ilker; Lacasce, Joseph Henry; Sanchez de la Lama, Marta; Trodahl, Marta (Peer reviewed; Journal article, 2019)The Lofoten Basin in the Nordic Seas plays a central role in the Atlantic overturning circulation by acting as a reservoir for the warm and saline Atlantic Water flow toward the Arctic Ocean. The mass and heat exchange ... -
The mesoscale eddy field in the Lofoten Basin from high-resolution Lagrangian simulations
Dugstad, Johannes Sandanger; Isachsen, Pål Erik; Fer, Ilker (Journal article; Peer reviewed, 2021)Warm Atlantic-origin waters are modified in the Lofoten Basin in the Nordic Seas on their way toward the Arctic. An energetic eddy field redistributes these waters in the basin. Retained for extended periods, the warm ... -
Norwegian Atlantic Slope Current along the Lofoten Escarpment
Fer, Ilker; Bosse, Anthony; Dugstad, Johannes Sandanger (Journal article; Peer reviewed, 2020-06)Observations from moored instruments are analyzed to describe the Norwegian Atlantic Slope Current at the Lofoten Escarpment (13∘ E, 69∘ N). The data set covers a 14-month period from June 2016 to September 2017 and resolves ... -
A numerical estimate of the tidal energy in the Lofoten area
Dugstad, Johannes Sandanger (Master thesis, 2014-05-28)In the following study the energy potential associated with tidal energy will be investigated. A depth integrated model based on the Navier Stokes equations and the continuity equation will be applied to simulate the tides ... -
Pathways and Water Mass Transformation Along and Across the Mohn‐Knipovich Ridge in the Nordic Seas
Ypma, Stefanie; Georgiou, S.; Dugstad, Johannes Sandanger; Pietrzak, J.D.; Katsman, C.A. (Journal article; Peer reviewed, 2020)Atlantic Water takes various pathways through the Nordic Seas, and its transformation to denser waters forms a crucial connection to the lower limb of the Atlantic Meridional Overturning Circulation. Circulation maps often ... -
Vertical structure and seasonal variability of the inflow to the Lofoten Basin inferred from high resolution Lagrangian simulations
Dugstad, Johannes Sandanger; Kozalka, Inga Monika; Isachsen, Pål Erik; Dagestad, Knut-Frode; Fer, Ilker (Peer reviewed; Journal article, 2019-11-13)The Lofoten Basin in the eastern Nordic Seas plays a central role in modifying the warm Atlantic Water inflow toward the Arctic Ocean. Here, the Atlantic Water experiences increased residence times, cooling, and substantial ... -
Water mass exchange, pathways and the mesoscale eddy field in the Lofoten Basin of the Norwegian Sea
Dugstad, Johannes Sandanger (Doctoral thesis, 2020-11-05)The Lofoten Basin situated in the Norwegian Sea, plays a central role in redistributing and modifying the warm Atlantic Water carried poleward with the Norwegian Atlantic Current. Increased residence time of the warm ...
