Two diol-epoxide metabolites of benzo[c]phenanthrene and benzo[a]pyrene, polynuclear aromatic hydrocarbons which occur in the environment, were tested for carcinogenicity by direct injection into the mammary fat pads of female CD rats. The compounds anti-3,4-dihydroxy-1,2-epoxy-1,2,3,4-tetrahydrobenzo[c]phenanthrene (BcPDE), a fjord region diol-epoxide, and anti-7,8-dihydroxy-9,10-epoxy-7,8,9,1...

Marine ecosystems, and particularly fjords, are experiencing an increasing level of human activity on a year-round basis, including the poorly studied winter period. To improve knowledge base for environmentally sustainable management in all seasons, this study provides hydrographic biological baseline data sub-Arctic fjord Kaldfjorden, Northern Norway (69.7° N, 18.7° E), between autumn 2017 sp...

Biogeochemical processes in fjords are likely affected by changes surrounding glacier cover but very little is known about how meltwater directly influences dissolved organic matter (DOM) fjords. Moreover, the data available restricted to a handful of northern hemisphere sites. Here we analyze seasonal and spatial variation carbon (DOC) concentration DOM composition (spectrofluorescence, ultrah...

We evaluate the hypothesis that Atlantic cod larvae are passively transported by sea currents from off-shore spawning areas to settle in coastal waters, a hypothesis which has recently gained support from genetic analysis of cod in the North Sea-Skagerrak area. Such larval transport has been suggested to be an important mechanism behind the commonly observed low spatial genetic differentiation ...

Culturing experiments were performed with the benthic foraminifer Ammonia aomo riensis from Flensburg Fjord, western Baltic Sea. The experiments simulated a projected rise in atmospheric CO2 concentrations. We exposed specimens to 5 seawater pCO2 levels ranging from 618 μatm (pH 7.9) to 3130 μatm (pH 7.2) for 6 wk. Growth rates and mortality differed significantly among pCO2 treatments. The hig...

Polar pelagic microbial communities access a narrower range of polysaccharide substrates than communities at lower latitudes. For example, the glucose-containing polysaccharide pullulan is typically not hydrolyzed in fjord waters of Svalbard, even though pullulan is rapidly hydrolyzed in sediments from Svalbard fjords, other polysaccharides are hydrolyzed rapidly in Svalbard waters, and pullula...

A spatially explicit coupled hydrodynamic-mass transport model system was used to simulate dispersal of particulate organic matter from Atlantic salmon (Salmo salar) farming in central Norway. Model setups of 32m horizontal resolution were run for periods of up to 650 days for 3 sites of different oceanographic characteristics: one fjord location, one medium-exposed location influenced by fjord...
