An along-track Biogeochemical Argo modelling framework: a case study of model improvements for the Nordic seas
Yumruktepe, Veli Çağlar; Mousing, Erik Askov; Tjiputra, Jerry; Samuelsen, Annette (Peer reviewed; Journal article, 2023)We present a framework that links in situ observations from the Biogeochemical Argo (BGC-Argo) array to biogeochemical models. The framework minimizes the technical effort required to construct a Lagrangian-type 1D modelling ... -
Implementation and evaluation of open boundary conditions for sea ice in a regional coupled ocean (ROMS) and sea ice (CICE) modeling system
Duarte, Pedro; Brændshøi, Jostein; Shcherbin, Dmitry; Barras, Pauline; Albretsen, Jon; Gusdal, Yvonne; Szapiro, Nicholas; Martinsen, Andreas Rostrup; Samuelsen, Annette; Wang, Keguang; Debernard, Jens Boldingh (Peer reviewed; Journal article, 2022)The Los Alamos Sea Ice Model (CICE) is used by several Earth system models where sea ice boundary conditions are not necessary, given their global scope. However, regional and local implementations of sea ice models require ... -
Key physical processes and their model representation for projecting climate impacts on subarctic Atlantic net primary production: A synthesis
Myksvoll, Mari Skuggedal; Sandø, Anne Britt; Tjiputra, Jerry; Samuelsen, Annette; Yumruktepe, Veli Caglar; Li, Camille; Mousing, Erik Askov; Bettencourt, Joao P.H.; Ottersen, Geir (Peer reviewed; Journal article, 2023)Oceanic net primary production forms the foundation of marine ecosystems. Understanding the impact of climate change on primary production is therefore critical and we rely on Earth System Models to project future changes. ... -
Mesoscale Eddies Are Oases for Higher Trophic Marine Life
Godø, Olav Rune; Samuelsen, Annette; Macaulay, Gavin J.; Patel, Ruben; Hjøllo, Solfrid Sætre; Horne, John K.; Kaartvedt, Stein; Johannessen, Johnny A. (Journal article; Peer reviewed, 2012-01-07) -
Particle aggregation at the edges of anticyclonic eddies and implications for distribution of biomass
Samuelsen, Annette; Hjøllo, Solfrid Sætre; Johannessen, Johnny Andre; Patel, Ruben (Journal article; Peer reviewed, 2012)Acoustic measurements show that the biomass of zooplankton and mesopelagic fish is redistributed by mesoscale variability and that the signal extends over several hundred meters depth. The mechanisms governing this ... -
Shelf recruitment of Calanus finmarchicus off the west coast of Norway: role of physical processes and timing of diapause termination
Samuelsen, Annette; Huse, Geir; Hansen, Cecilie (Journal article; Peer reviewed, 2009-07-02)The copepod Calanus finmarchicus is an important part of the Norwegian Sea ecosystem because of its dominating abundance and importance as prey for fish larvae and adult planktivorous fish. The abundance of C. finmarchicus ... -
Tuning and assessment of the HYCOM-NORWECOM V2.1 biogeochemical modeling system for the North Atlantic and Arctic oceans
Samuelsen, Annette; Hansen, Cecilie; Wehde, Henning (Journal article; Peer reviewed, 2015) -
Virvler i havet skaper oaser av liv
Samuelsen, Annette; Hjøllo, Solfrid Sætre (Chronicle, 2012-03-31)
