  Q3 Gear casts

  pi_name: Marit Reigstad
  

  Abstract

  The RV Kronprins Haakon cruise Nansen Legacy seasonal Q3 (Q3= 3rd quarter of the year), initiated the seasonal investigation of the northern Barents Sea and adjacent Arctic Basin. This activity is a key milestone for 2019 and 2020. The cruise addressed objectives of the research foci in RF1 on Physical drivers, RF2 on Human drivers and RF3 on the living Barents Sea, and collected necessary data along the Nansen Legacy transect in open waters and within the ice. Experiments were an important component of the research to quantify processes, rates and interactions that will also feed modeling work and projections in RF4. The ongoing establishment of routines for sampling, data management and data storing continued as part of the practical work onboard. The observational capacity was increased also outside the cruise periods, through deployment of 2 gliders for RF1, and 3 moorings in collaboration with RF1/2/3.

  T2-2.5 Critical seasonal windows of responses to multiple stressors on key organisms of benthic and pelagic food chains

  pi_name: Oystein Varpe
  

  Abstract

  Due to climate change and pollution Arctic ecosystems are exposed to multiple stressors. Arctic ecosystems are highly seasonal and include substantial changes in the lipid composition of the organisms throughout the year. In periods with lipid mobilization many marine species will be prone to external stressors which may influence their ecology, physiology and biochemistry. These “critical periods of effects” (when energy stores are depleted and pollutants are remobilized from lipids to blood and other body organs) need to be determined in Arctic species belonging to the benthic and pelagic food chain. Key species in the benthic (amphipods, bivalves and common eiders) and pelagic (macrozooplankton, polar cod and kittiwakes) food web will be sampled throughout the year, with seabird data primarily from collaboration with ongoing and NPI lead work in breeding colonies. For fish and birds, organ specific distributions of pollutants and organ specific annual composition of fat, protein and energy will be quantified to determine their critical periods of effects in relation to time of year. From this, combined with habitat use and activity levels, critical periods of effects can be predicted.

  Effects of changes in species composition and distribution on contaminant food web accumulation

  pi_name: Katrine Borgå
  

  Abstract

  Work description As changes in temperature and sea ice distribution and thickness is expected in the region of interest, the energy transfer processes in the food web are expected to be changed compared to previous decades. Zooplankton and fish samples will be collected focusing on the process study cruises. From these, chemicals representing lipid soluble and protein associated contaminants will be analyzed, in addition to dietary descriptors to trace energy source (stable isotopes and lipid analyses). This will be repeated in the different seasons to interpret the annual dynamics of contaminant accumulation and transfer in the food web related to energy use and availability. So far, seasonal food web data are only available from Arctic fjords. At the UiO stable isotope lab, we will measure bulk C, H, N, O and S in organic material, and thus the ratios between lipid/protein/carbohydrate will be analyzed in small amounts of sample without extraction to assess the proximate biochemical composition. Model predictions of climate change effect on food web accumulation of contaminants include reduced accumulation due to predicted reduction in lipid storage. Bioaccumulation changes due to altered dietary composition is predicted to have less influence than the predicted lower lipid content. These predictions will be tested in the present task. A similar approach of sampling the central Barents Sea pelagic food web was taken in May 1998 (however, only with bulk stable isotope analyses of 13C and 15N), which allows a thorough comparison between the environmental states two decades apart.

  T2-2.5 Critical seasonal windows of responses to multiple stressors on key organisms of benthic and pelagic food chains

  pi_name: Oystein Varpe
  

  Abstract

  Due to climate change and pollution Arctic ecosystems are exposed to multiple stressors. Arctic ecosystems are highly seasonal and include substantial changes in the lipid composition of the organisms throughout the year. In periods with lipid mobilization many marine species will be prone to external stressors which may influence their ecology, physiology and biochemistry. These “critical periods of effects” (when energy stores are depleted and pollutants are remobilized from lipids to blood and other body organs) need to be determined in Arctic species belonging to the benthic and pelagic food chain. Key species in the benthic (amphipods, bivalves and common eiders) and pelagic (macrozooplankton, polar cod and kittiwakes) food web will be sampled throughout the year, with seabird data primarily from collaboration with ongoing and NPI lead work in breeding colonies. For fish and birds, organ specific distributions of pollutants and organ specific annual composition of fat, protein and energy will be quantified to determine their critical periods of effects in relation to time of year. From this, combined with habitat use and activity levels, critical periods of effects can be predicted.
