Eddy-resolving simulations of the Fimbul Ice Shelf cavity circulation: Basal melting and exchange with open ocean
Hattermann, Tore; Smedsrud, Lars Henrik; Nøst, Ole Anders; Lilly, Jonathan M.; Galton-Fenzi, Ben K. (Peer reviewed; Journal article, 2014-10)Melting at the base of floating ice shelves is a dominant term in the overall Antarctic mass budget. This study applies a high-resolution regional ice shelf/ocean model, constrained by observations, to (i) quantify present ... -
Necessary Conditions for Warm Inflow Toward the Filchner Ice Shelf, Weddell Sea
Daae, Kjersti; Hattermann, Tore; Darelius, Elin Maria K.; Mueller, Rachael D.; Naughten, Kaitlin A; Timmermann, Ralph; Hellmer, Hartmut H. (Journal article; Peer reviewed, 2020)Understanding changes in Antarctic ice shelf basal melting is a major challenge for predicting future sea level. Currently, warm Circumpolar Deep Water surrounding Antarctica has limited access to the Weddell Sea continental ... -
Observing Antarctic Bottom Water in the Southern Ocean
Silvano, Alessandro; Purkey, Sarah; Gordon, Arnold L.; Castagno, Pasquale; Stewart, Andrew L.; Rintoul, Stephen R.; Foppert, Annie; Gunn, Kathryn L.; Herraiz-Borreguero, Laura; Aoki, Shigeru; Nakayama, Yoshihiro; Naveira Garabato, Alberto C.; Spingys, Carl; Akhoudas, Camille Hayatte; Sallée, Jean-Baptiste; de Lavergne, Casimir; Abrahamsen, E. Povl; Meijers, Andrew J. S.; Meredith, Michael P.; Zhou, Shenjie; Tamura, Takeshi; Yamazaki, Kaihe; Ohshima, Kay I.; Falco, Pierpaolo; Budillon, Giorgio; Hattermann, Tore; Janout, Markus A.; Llanillo, Pedro; Bowen, Melissa M.; Darelius, Elin Maria K.; Østerhus, Svein; Nicholls, Keith W.; Stevens, Craig; Fernandez, Denise; Cimoli, Laura; Jacobs, Stanley S.; Morrison, Adele K.; Hogg, Andrew McC.; Haumann, F. Alexander; Mashayek, Ali; Wang, Zhaomin; Kerr, Rodrigo; Williams, Guy D.; Lee, Won Sang (Journal article; Peer reviewed, 2023)Dense, cold waters formed on Antarctic continental shelves descend along the Antarctic continental margin, where they mix with other Southern Ocean waters to form Antarctic Bottom Water (AABW). AABW then spreads into the ... -
On the effect of topography and wind on warm water inflow— An idealized study of the southern Weddell Sea continental shelf system
Daae, Kjersti; Hattermann, Tore; Darelius, Elin Maria K.; Fer, Ilker (Peer reviewed; Journal article, 2017-03)An idealized eddy-resolving numerical model, with topographic features common to the southern Weddell Sea, is constructed to study mechanisms through which warm deep water enters a wide continental shelf with a trough. The ... -
Phenology and Environmental Control of Phytoplankton Blooms in the Kong Håkon VII Hav in the Southern Ocean
Kauko, Hanna Maria; Hattermann, Tore; Ryan-Keogh, Thomas J.; Singh, Asmita; de Steur, Laura; Fransson, Agneta; Chierici, Melissa; Falkenhaug, Tone; Hallfredsson, Elvar H.; Bratbak, Gunnar; Tsagaraki, Tatiana Margo; Berge, Terje; Zhou, Qin; Moreau, Sebastien (Journal article; Peer reviewed, 2021)Knowing the magnitude and timing of pelagic primary production is important for ecosystem and carbon sequestration studies, in addition to providing basic understanding of phytoplankton functioning. In this study we use ... -

Upstream sources of the Denmark Strait Overflow: Observations from a high-resolution mooring array
Harden, Benjamin E.; Pickart, Robert S.; Valdimarsson, Héðinn; Våge, Kjetil; de Steur, Laura; Richards, Clark; Bahr, Frank; Torres, Dan; Børve, Eli; Jónsson, Steingrímur; Macrander, Andreas; Østerhus, Svein; Håvik, Lisbeth; Hattermann, Tore (Peer reviewed; Journal article, 2016)We present the first results from a densely instrumented mooring array upstream of the Denmark Strait sill, extending from the Iceland shelfbreak to the Greenland shelf. The array was deployed from September 2011 to July ... -
Warming beneath an East Antarctic ice shelf due to increased subpolar westerlies and reduced sea ice
Lauber, Julius; Hattermann, Tore; de Steur, Laura; Chiche, Elin Maria Kristina Darelius; Auger, Matthis; Nøst, Ole Anders; Moholdt, Geir (Journal article; Peer reviewed, 2023)Understanding how climate change influences ocean-driven melting of the Antarctic ice shelves is one of the greatest challenges for projecting future sea level rise. The East Antarctic ice shelf cavities host cold water ... -
