Response of halocarbons to ocean acidification in the Arctic
(Journal article; Peer reviewed, 2013)The potential effect of ocean acidification (OA) on seawater halocarbons in the Arctic was investigated during a mesocosm experiment in Spitsbergen in June–July 2010. Over a period of 5 weeks, natural phytoplankton communities ... -
Temporal biomass dynamics of an Arctic plankton bloom in response to increasing levels of atmospheric carbon dioxide
(Journal article; Peer reviewed, 2013)Ocean acidification and carbonation, driven by anthropogenic emissions of carbon dioxide (CO2), have been shown to affect a variety of marine organisms and are likely to change ecosystem functioning. High latitudes, ... -
Membrane bioreactors (MBRs): Activated sludge filterability and full-scale MBR functioning
(Journal article; Peer reviewed, 2013)Despite continuous developments in the field of MBR technology, membrane fouling together with the associated energy demand and related costs issues remain major challenges. The efficiency of the filtration process in an ... -
CO2 increases C-14 primary production in an Arctic plankton community
(Journal article; Peer reviewed, 2013)Responses to ocean acidification in plankton communities were studied during a CO2-enrichment experiment in the Arctic Ocean, accomplished from June to July 2010 in Kongsfjorden, Svalbard (78°56′ 2′′ N, 11°53′ 6′′ E). ... -
Contrasting responses of DMS and DMSP to ocean acidification in Arctic waters
(Journal article; Peer reviewed, 2013)Increasing atmospheric CO2 is decreasing ocean pH most rapidly in colder regions such as the Arctic. As a component of the EPOCA (European Project on Ocean Acidification) pelagic mesocosm experiment off Spitzbergen in 2010, ... -
Cardiac molecular-acclimation mechanisms in responseto swimming-induced exercise in atlantic salmon
(Journal article; Peer reviewed, 2013)Cardiac muscle is a principal target organ for exercise-induced acclimation mechanisms in fish and mammals, given that sustained aerobic exercise training improves cardiac output. Yet, the molecular mechanisms underlying ... -
«Gigant-mikroben» sjøplomme Nostoc pruniforme i Slettnes naturreservat på Nordkinnhalvøya, Finnmark
(Journal article; Peer reviewed, 2013)This article is the first comprehensive account about the occurrence of the cyanobacterium Nostoc pruniforme in Norway. The investigation was carried out in a rocky pool inhabited by the species. The locality is situated ... -
Kan informasjon om bløtbunnssamfunn og modeller for geofysiske forhold gi heldekkende kart over naturtilstanden i norske kystvann?
(Journal article; Peer reviewed, 2013)Artsmangfold og sammensetning av dyr i marine sedimenter (bløtbunnsfauna) er spesielt egnet for å måle miljøets tilstand, fordi ulike typer partikkelbundet forurensning før eller senere når havbunnen. Indekser på artsmangfold ... -
Effect of water treatment on the growth potential of Vibrio cholerae and Vibrio parahaemolyticus in seawater
(Journal article; Peer reviewed, 2013)In laboratory experiments we added Vibrio cholerae and Vibrio parahaemolyticus to bottles with seawater previously treated by filtration, UV, chlorine or ozone. The purpose was to investigate the influence of different ... -
Faunal trophic structure at hydrothermal vents on the southern Mohn's Ridge, Arctic Ocean
(Journal article; Peer reviewed, 2013)We explore the trophic ecology of heterotrophic fauna associated with a high temperature (HT) vent, 2 low temperature vents, a ‘near-HT vent’ habitat and a non-vent site situated at upper bathyal depths on the southern ... -
Combined and interactive effects of global climate change and toxicants on populations and communities
(Journal article; Peer reviewed, 2013)Increased temperature and other environmental effects of global climate change (GCC) have documented impacts on many species (e.g., polar bears, amphibians, coral reefs) as well as on ecosystem processes and species ... -
Atmospheric mercury inputs in montane soils increase with elevation: evidence from mercury isotope signatures
(Journal article; Peer reviewed, 2013)The influence of topography on the biogeochemical cycle of mercury (Hg) has received relatively little attention. Here, we report the measurement of Hg species and their corresponding isotope composition in soil sampled ... -
Håp for kjønnsforstyrrede snegler – overvåking av imposex og intersex viser at forbud mot TBT har hatt positiv effekt
(Journal article; Peer reviewed, 2013)Tributyltinn (TBT) er et giftstoff som har vært brukt som begroingshindrende tilsetning i skipsmaling siden 1960-tallet. TBT forårsaker kjønnsforstyrrelser hos marine snegler, hvor hunner utvikler maskuline kjønnskarakterer. ... -
Optical water types of the Nordic Seas and adjacent areas
(Journal article; Peer reviewed, 2013)A new map of Jerlov's optical water types in the Nordic Seas and adjacent waters at 139 locations, as well as a table with statistical and geographical properties of the vertical attenuation coefficient of downward irradiance ... -
Passive sampling methods for contaminated sediments: risk assessment and management
(Journal article; Peer reviewed, 2013)This paper details how activity-based passive sampling methods (PSMs), which provide information on bioavailability in terms of freely dissolved contaminant concentrations (Cfree), can be used to better inform risk management ... -
