Atlantic water properties, transport and heat loss from mooring observations north of Svalbard

The Atlantic Water inflow to the Arctic Ocean is transformed and modified in the area north of Svalbard, which influences the Arctic Ocean heat and salt budget. Year-round observations are relatively sparse in this region partially covered by sea ice. We took advantage of one-year-long records of ocean currents and hydrography from seven moorings north of Svalbard. The moorings are organized in two arrays separated by 94 km along the path of the Atlantic Water inflow to investigate the properties, transport and heat loss of the Atlantic Water in 2018/2019. The Atlantic Water volume transport varies from 0.5 Sv (1 Sv = 106 m3s−1) in spring to 2 Sv in fall. The first mode of variation of the Atlantic Water inflow temperature is a warm/cold mode with a seasonal cycle. The second mode corresponds to a shorter time scale (6–7 days) variability in the onshore/offshore displacement of the temperature core linked to the mesoscale variability. Heat loss from the Atlantic Water in this region is estimated, for the first time using two mooring arrays and conserving the volume transport. The heat loss varies between 302 W m−2 in winter to 60 W m−2 in spring. The onshore moorings show a westward countercurrent driven by Ekman setup in spring, carrying transformed-Atlantic Water. The offshore moorings show a bottom-intensified current that covaries with the wind stress curl. These two mooring arrays allowed for a better comprehension of the structure and transformation of the slope currents north of Svalbard.publishedVersio

Sampling protocol for the determination of nutrients and contaminants in fish and other seafood – The EAF-Nansen Programme

Seafood plays a central role in global food and nutrition security. However, there is a lack of data on the concentration of nutrients and contaminants in fish and other seafood, especially in low- and middle-income countries. In order to assess the potential risks and benefits associated with seafood intake, reliable and up-to-date food composition data is crucial. The quality of food composition data is affected by several factors, such as sampling protocols and the suitability and quality of the methods applied for sample preparation and analysis. In this paper, we describe the sampling methodology and protocols related to the sampling of fish and other seafood and the corresponding analytical methods used to analyse the nutrient and contaminant content of such species. For nutrients, the determination of protein, fat, ash, energy, fatty acids, cholesterol, and amino acids is described, in addition to analyses for determination of the vitamin and mineral content in fish and other seafood. For contaminants, analyses for the determination of organic pollutants and microplastics are described. The methodology described in this paper is used for sampling data through scientific surveys in low- and middle-income countries with research vessel Dr. Fridtjof Nansen under the EAF-Nansen Programme. The Programme aims to improve knowledge on the nutritional composition of fish and ensure the fish is safe to consume. •In this paper, we describe the sampling protocols used for sampling fish and other seafood during scientific surveys under the EAF-Nansen Programme. •This paper describes the methodology and quality control for analysing nutrients and contaminants in fish and other seafood.publishedVersio

Norge etter 22. juli

"At the time of this book’s publication, almost seven years have passed since the dramatic and brutal terror attacks at Norway’s Government Headquarters in Oslo and the island of Utøya on 22 July 2011. How have we coped during this time? Which values have been important? Have we managed to protect the ideals of democracy, openness and humanity? And not least: Who is this ""we"" that we are referring to? This scholarly anthology includes articles from researchers associated with the project NECORE (Negotiating Values: Collective Identities and Resilience after 22 July) and other researchers whose work is closely associated with the project. They give us insights, opinions and sharp perspectives on not just 22 July, but also about Norway today, about values, identities and resilience in Norwegian society in the wake of the terror attacks. An important backdrop for the book and the project is the assertion that, as the events themselves recede into the past, it is even more important to focus on what the terror events have led to and how we can learn from them. In a world where terrorism has become an all too common part of political reality, it is crucial that we understand how we ought to think about terror, and how we as a society encounter it.
