Age readings of Sebastes marinus otoliths: bias and precision between readers and otolith preparation methods
Stransky, Christoph; Guðmundsdóttir, Sif; Sigurdsson, Thorsteinn; Lemvig, Svend; Nedreaas, Kjell Harald (ICES CM documents, Working paper, 2001)This study presents a comparative age reading on Sebastes marinus from the Icelandic shelf within an otolith exchange program between institutes in Germany, Iceland and Norway. Out of a series of 212 otolith pairs, ... -

New evidence for the establishment of coastal cod Gadus morhua in Svalbard fjords
Spotowitz, Lisa; Johansen, Torild; Hansen, Agneta; Berg, Erik; Stransky, Christoph; Fischer, Philipp (Peer reviewed; Journal article, 2022)The Arctic is experiencing increasing water temperatures, leading to a northward shift of Atlantic species into Arctic waters. Arctic marine ecosystems are therefore subject to substantial changes in species distributions ... -
