Integrated Ecosystem Assessment of East Greenland Waters

Søren Post, Jesper Boje, AnnDorte Burmeister, Henrik Christiansen et autres

This report presents results from a Nordic project (2023–2025) on understanding the marine ecosystem off East Greenland. It brings together scientists, local stakeholders, and communities to share knowledge about a region undergoing rapid environmental change. The study highlights how ocean conditions are …

West Greenland Atlantis Model Input Parameters, Data Sources and Overview of Data Availability

J. Rasmus Nielsen, Søren Post, Torkel Gissel Nielsen, AnnDorte Burmeister et autres

Data catalogue and review of available data (and parameters) and their sources for parameterization of an Atlantis end-to-end holistic ecosystem model in the West Greenland marine ecosystem covering inshore, coastal and offshore waters. Documentation in relation to potential model implementation.

The East Greenland Polar Front as a Mediator of Climate‐Ocean‐Ecosystem Variability Along Southeast Greenland

Caroline V. B. Gjelstrup, Jesper Boje, Brian R. MacKenzie, Søren Post et autres

Abstract The southeast Greenland region features a confluence of Arctic‐ and Atlantic origin waters along the continental shelf‐break, forming the East Greenland Polar Front (EGPF). Here we examine the role of the EGPF in mediating climate‐ocean‐ecosystem variability. We observe systematic temporal variability …

Population structure of Greenland halibut across the North Atlantic inferred from large-scale monitoring and spatial modelling

Martin Lindegren, Magnús Thorlacius, James T. Thorson, Bjarki Þór Elvarsson et autres

Abstract The Greenland halibut (Reinhardtius hippoglossoides) is an ecologically and economically important marine fish species in the Northern Hemisphere. In the North Atlantic, the current spatial management units comprise four large offshore stocks and eight additional inshore stocks. However, the underlying biological …

An interdisciplinary approach to detect and grade ‘Mushy Halibut Syndrome’ in fillets of Greenland halibut (Reinhardtius hippoglossoides)

Natacha L. Severin, Samuel Ortega, Rowan Romeyn, Stein Harris Olsen et autres

Abstract ‘Mushy halibut syndrome’ (MHS) affects the quality of Greenland halibut fillets. Fillets affected by MHS are jelly-like and turn mushy when cooked. Different severities of MHS occur in commercial catches, and cause food wastage and economic losses due to a lack …

Sex Influences the Genetic Structure of Greenland Halibut in the North Atlantic

D.A. García Estévez, Denis Roy, Mikko Vihtakari, Davíð Gíslason et autres

) is a commercially important species in the North Atlantic whose spatial population structure has not yet been fully determined across its entire range. We genotyped individuals from across the North Atlantic using a subset of informative single nucleotide polymorphic (SNP) markers …

Sex influence on the genetic structure of Greenland halibut, Reinhardtius hippglossoides (Walbaum, 1792), in the North Atlantic

D.A. García Estévez, Denis Roy, Mikko Vihtakari, Davíð Gíslason et autres

Greenland halibut (Reinhardtius hippoglossoides) is a commercially important species in the North Atlantic whose spatial population structure has not yet been fully determined.To help resolve this issue further, we genotyped individuals from across the North Atlantic using a subset of previously identified, …

Using multivariate autoregressive state‐space models to examine stock structure of Greenland halibut in the North Atlantic

Adriana Nogueira, Nick Tolimieri, Mikko Vihtakari, Bjarki Þór Elvarsson et autres

Abstract Accurate information on population structure is essential for effective fisheries management. Greenland halibut (Reinhardtius hippoglossoides) in the North Atlantic is managed as four separate offshore stocks. We use Multivariate Autoregressive State‐Space (MARSS) models to assess population structure by means of abundance …

Population structure discovered in juveniles of Greenland halibut (Reinhardtius hippoglossoidesWalbaum, 1792)

Davíð Gíslason, D.A. García Estévez, Sæmundur Sveinsson, Agneta Hansen et autres

Abstract Understanding the genetic differentiation among populations of most marine fish requires investigating the differences among spawning grounds. However, this can be challenging as spawning grounds for some species are not well known, or spawning fish are difficult to collect. An alternative …

Migration patterns of Greenland halibut in the North Atlantic revealed by a compiled mark–recapture dataset

Mikko Vihtakari, Bjarki Þór Elvarsson, Margaret A. Treble, Adriana Nogueira et autres

Abstract Marine fisheries are often allocated to stocks that reflect pragmatic considerations and may not represent the species’ spatial population structure, increasing the risk of mismanagement and unsustainable harvesting. Here we compile mark–recapture data collected across the North Atlantic to gain insight …
