The One Ocean Expedition (OOE) was a 20-month long circumnavigation of the globe by the Norwegian sail training vessel Statsraad Lehmkuhl, and a recognised part of the UN decade of Ocean Science for Sustainable Development. The ship was equipped with modern instrumentation to collect high-quality data on ocean physics, chemistry, and biology. Many of the data series were available in near real time ...

Since the mid-1990s, traceability has become a popular concept in industrial logistics, regardless of the production regime and type of product. Implementing traceability systems across the food supply chain is seen as crucial for increasing food quality and safety, for optimizing production or for documenting sustainability. However, implementation of traceability systems in the seafood sector seems ...

Presentasjon av institusjonelle utviklingstrekk i fiskeri- og havbruksforvaltning. Samspill mellom regulering, næringstilpasning og teknologi.

Parallelt med tiltagende lukking av de store fiskeriene i Norge, har det skjedd en nedgang i antall fiskere, samtidig som også færre rekrutteres til fiske. Spørsmålet her er om fiskere har blitt skjøvet ut av yrket eller om de har sluttet av andre grunner? En undersøkelse blant fiskere som har sluttet, tyder på at utviklinga i andre næringer og i samfunnet har hatt innvirkning på sysselsettingssystemet ...

The decrease in Arctic sea-ice extent and thickness as a result of global warming will impact the timing, duration, magnitude and composition of phytoplankton production with cascading effects on Arctic marine food-webs and biogeochemical cycles. Here, we elucidate the environmental drivers shaping the composition, abundance, biomass, trophic state and vertical flux of protists (unicellular eukaryotes), ...

Objectives - This empirical study investigated the relationship between globalisation and suicide rates. We examined whether there is a beneficial or harmful relationship between economic, political and social globalisation and the suicide rate. We also estimated whether this relationship differs in high-, middle- and low-income countries.<p> <p>Study design - Using panel data from 190 countries ...

Cultivation of sterile-only fish in aquaculture offers multiple benefits of environmental, economical, and social value. A reliable method for efficient sterilization without affecting fish welfare and performance traits would have significant impact on fish production practices. Here, we demonstrate sterilization of Atlantic salmon embryos by targeting the dead end gene with antisense oligonucleotides. ...

Oceanographic changes adjacent to Antarctica have global climatic and ecological impacts. However, this is the most challenging place in the world to obtain marine data due to its remoteness and inhospitable nature, especially in winter. Here, we present more than 2000 Conductivity-Temperature-Depth (CTD) profiles and associated water sample data collected with (almost uniquely) full year-round ...

There is an urgent need to understand and address the risks associated with a warming climate for ecosystems and societies in the Arctic and sub-Arctic regions. There are major gaps in our understanding of the complex effects of climate change—including extreme events, cascading impacts across ecosystems, and the underlying socioecological dynamics and feedbacks—all of which need collaborative efforts ...

The Svalbard white whale (Delphinapterus leucas) population is one of the smallest in the world, making it particularly vulnerable to challenges such as climate change and pathogens. In this study, serum samples from live captured (2001-2016) white whales from this region were investigated for influenza A virus (IAV) antibodies (Abs) (n = 27) and RNA (n = 25); morbillivirus (MV) Abs (n = 3) and RNA ...
