    • Circulation and Exchanges at High-latitude Ocean Margins: Dynamical models and Observations from Instrumented Seals 

      Zhou, Qin (Doctoral thesis; Doktorgradsavhandling, 2014-01-14)
      Circulation and exchange processes at high-latitude ocean margins are investigated in this thesis, by using analytical models, numerical simulations and hydrographic data. In the Northern Hemisphere, the establishment of Atlantic Water transport as a topographically steered slope current has been investigated. A simplified analytical model based on geostrophic balance predicts that buoyancy loss ...

    • The Framework for Ice Sheet-Ocean Coupling (FISOC) V1.1 

      Gladstone, Rupert; Galton-Fenzi, Benjamin K.; Gwyther, David; Zhou, Qin; Hattermann, Tore; Zhao, Chen; Jong, Lenneke; Xia, Yuwei; Guo, Xiaoran; Petrakopoulos, Konstantinos; Zwinger, Thomas; Shapero, Daniel; Moore, John C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-11)
      A number of important questions concern processes at the margins of ice sheets where multiple components of the Earth system, most crucially ice sheets and oceans, interact. Such processes include thermodynamic interaction at the ice–ocean interface, the impact of meltwater on ice shelf cavity circulation, the impact of basal melting of ice shelves on grounded ice dynamics and ocean controls on ...

    • Impact of the Nares Strait sea ice arches on the long-term stability of the Petermann Glacier ice shelf 

      Prakash, Abhay; Zhou, Qin; Hattermann, Tore; Kirchner, Nina (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-12)
      One of the last remaining floating tongues of the Greenland ice sheet (GrIS), the Petermann Glacier ice shelf (PGIS), is seasonally shielded from warm Atlantic water (AW) by the formation of sea ice arches in the Nares Strait. However, continued decline of the Arctic sea ice extent and thickness suggests that arch formation is likely to become anomalous, necessitating an investigation into ...

    • Jellyfish summer distribution, diversity and impact on fish farms in a Nordic fjord 

      Halsband, Claudia; Majaneva, Sanna Kristiina; Hosia, Aino; Emaus, Per; Gaardsted, Frank; Zhou, Qin; Nøst, Ole Anders; Renaud, Paul Eric (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-19)
      Jellyfish can cause high mortality of farmed fish and hence significant economic losses for the aquaculture industry. Despite their socio-economic importance, distribution and diversity data on gelatinous plankton are scarce from northern Norwegian fjords and other Nordic systems. Intense blooms of jellyfish have repeatedly been observed in Ryggefjord, Finnmark (Norway), sometimes concurrent with ...

    • A nested high-resolution unstructured grid 3-D ocean-sea ice-ice shelf setup for numerical investigations of the Petermann ice shelf and fjord 

      Prakash, Abhay; Zhou, Qin; Hattermann, Tore; Bao, Weiyang; Graversen, Rune Grand; Kirchner, Nina (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-18)
      Three-dimensional numerical simulation of circulation in fjords hosting marine-terminating ice shelves is challenging because of the complexity of processes involved in such environments. This often requires a comprehensive model setup. The following elements are needed: bathymetry (usually unknown beneath the glacier tongue), ice shelf draft (impacting water column thickness), oceanographic state ...
