Antarctic krill and ecosystem monitoring survey off the South Orkney Islands in 2023
Krafft, Bjørn Arne; Pedersen, Ronald; Zhang, Guosong; Menze, Sebastian; Rasmussen, Astrid Fuglseth; Skaar, Hege; Dale, Julian; Biuw, Martin; Oosthuisen, Chris; Lowther, Andrew (Toktrapport;2023 - 8, Research report, 2023)Environmental monitoring along 5 set transect lines off South Orkney Islands in the Southern Ocean have been carried out annually (since 2011) by the Institute of Marine Research, Norway. Data are used to calculate biomass ... -
Atlantic Water Pathways Along the North-Western Svalbard Shelf Mapped Using Vessel-Mounted Current Profilers
Menze, Sebastian; Ingvaldsen, Randi Brunvær; Haugan, Peter M.; Fer, Ilker; Sundfjord, Arild; Beszczynska-Moeller, Agnieszka; Falk-Petersen, Stig (Journal article; Peer reviewed, 2019)A large amount of warm Atlantic water (AW) enters the Arctic as a boundary current through Fram Strait (West Spitsbergen Current [WSC]) and is the major oceanic heat source to the Arctic Ocean. Along the north‐western ... -
Estimating the spatial distribution of vocalizing animals from ambient sound spectra using widely spaced recorder arrays and inverse modelling
Menze, Sebastian; Zitterbart, Daniel P.; Biuw, Martin; Boebel, Olaf (Journal article; Peer reviewed, 2019)The sound energy from marine mammal populations vocalizing over extended periods of time adds up to quasi-continuous “choruses,” which create characteristic peaks in marine sound spectra. An approach to estimate animal ... -
Ocean acidification state variability of the Atlantic Arctic Ocean around northern Svalbard
Jones, Elizabeth Marie; Chierici, Melissa; Menze, Sebastian; Fransson, Agneta; Ingvaldsen, Randi Brunvær; Lødemel, Helene Hodal (Peer reviewed; Journal article, 2021)The Svalbard shelf and Atlantic Arctic Ocean are a transition zone between northward flowing Atlantic Water and ice-covered waters of the Arctic. Effects of regional ocean warming, sea ice loss and greater influence of ... -
Productive detours – Atlantic water inflow and acoustic backscatter in the major troughs along the Svalbard shelf
Menze, Sebastian; Ingvaldsen, Randi Brunvær; Nikolopoulos, Anna; Hattermann, Tore; Albretsen, Jon; Gjøsæter, Harald (Peer reviewed; Journal article, 2020)Atlantic Water (AW) flowing along the western and northern Svalbard shelf-break extends the Atlantic domain into the Arctic and is the region’s major source of heat, nutrients and advected plankton. We investigated the ... -
The influence of sea ice, wind speed and marine mammals on Southern Ocean ambient sound
Menze, Sebastian; Zitterbart, Daniel P.; van Opzeeland, Ilse; Boebel, Olaf (Journal article; Peer reviewed, 2017)This paper describes the natural variability of ambient sound in the Southern Ocean, an acoustically pristine marine mammal habitat. Over a 3-year period, two autonomous recorders were moored along the Greenwich meridian ...
