Diversity and seasonal development of large zooplankton along physical gradients in the Arctic Barents Sea
Engeland, Tom Van; Bagøien, Espen; Wold, Anette; Cannaby, Heather Anne; Majaneva, Sanna Kristiina; Vader, Anna; Rønning, Jon S.; Handegard, Nils Olav; Dalpadado, Padmini; Ingvaldsen, Randi Brunvær (Peer reviewed; Journal article, 2023)Due to ongoing climate change, a new Arctic Ocean ecosystem is emerging. Within the framework of the Nansen Legacy project, we investigated the community composition of the large zooplankton and its seasonal development ... -
Environmental controls on macrozooplankton and fish distributions over diurnal to seasonal time scales in the northern Barents Sea
Cannaby, Heather Anne; Ingvaldsen, Randi Brunvær; Lundesgaard, Øyvind; Renner, Angelika; Skaret, Georg; Sakinan, Serdar S.; Chierici, Melissa; Gjøsæter, Harald (Peer reviewed; Journal article, 2023)We present acoustic observations obtained by bottom mounted echosounders at two locations in the northern Barents Sea and a third on the northern continental slope of the Barents Sea. Data collected over a period of ... -
Numerical models and long term monitoring - How can numerical models be used to support in situ sampling and survey design for long term hydrographic monitoring in standard sections?
Cannaby, Heather Anne; Albretsen, Jon; Ingvaldsen, Randi Brunvær; Lien, Vidar Surén; Mork, Kjell Arne (Rapport fra havforskningen;2024 - 18, Research report, 2024)As a part of regular monitoring of the marine environment, IMR conducts 10 fixed transects on a multiannual basis during which hydrographical, chemical and plankton data are collected at the same positions several times a ... -
Under-ice observations by trawls and multi-frequency acoustics in the Central Arctic Ocean reveals abundance and composition of pelagic fauna
Ingvaldsen, Randi Brunvær; Eriksen, Elena; Gjøsæter, Harald; Engås, Arill; Schuppe, Birte Katarina; Assmann, Karen; Cannaby, Heather Anne; Dalpadado, Padmini; Bluhm, Bodil (Peer reviewed; Journal article, 2023)The rapid ongoing changes in the Central Arctic Ocean call for baseline information on the pelagic fauna. However, sampling for motile organisms which easily escape vertically towed nets is challenging. Here, we report the ...
