An important yet still not well documented aspect of recent changes in the Arctic Ocean is associated with advection anomalous sub-Arctic Atlantic- and Pacific-origin waters biota into polar basins, a process which we refer to as borealization. Using 37-year archive observations (1981–2017) demonstrate dramatically contrasting regional responses atlantification (that part borealization related progression anomalies from Atlantic sector seas Ocean) pacification (the counterpart influx Pacific...
Todays physical oceanography and primary secondary production was investigated for the entire Arctic Ocean with physical-biologically coupled SINMOD model. To obtain indications on effect of climate change in 21th century magnitude change, where when these may take place forced down-scaled trajectories International Panel Climate Change A1B scenario which appears to predict an average global atmospheric temperature increase 3.5 4 °C at end this century. It is projected that some surface...
Ongoing climate warming is causing a dramatic loss of sea ice in the Arctic Ocean, and it projected that Ocean will become seasonally ice-free by 2040. Many studies local food webs now exist, with this review paper we aim to synthesize these into large-scale assessment current status knowledge on structure various marine their response change, sea-ice retreat particular. Key drivers ecosystem change potential consequences for functioning are identified along gradient, special emphasis...
Currents, wind, bathymetry, and freshwater runoff are some of the factors that make coastal waters heterogeneous, patchy, scientifically interesting-where it is challenging to resolve spatiotemporal variation within water column. We present methods results from field experiments using an autonomous underwater vehicle (AUV) with embedded algorithms focus sampling on features in three dimensions. This was achieved by combining Gaussian process (GP) modeling onboard robotic autonomy, allowing...
Continental slopes – steep regions between the shelf break and abyssal ocean play key roles in climatology ecology of Arctic Ocean. Here, through review synthesis, we find that narrow slope contribute to ecosystem functioning disproportionately size habitat area (∼6% total Ocean area). Driven by inflows sub-Arctic waters steered topography, boundary currents transport boreal properties particle loads from Atlantic Pacific Oceans along-slope, thus creating both along cross-slope connectivity...
Abstract In recent decades, the central Arctic Ocean has been experiencing dramatic decline in sea ice coverage, thickness and extent, which is expected to have a tremendous impact on all levels of marine life. Here, we analyze regional temporal changes pan‐Arctic distribution population structure key zooplankton species Calanus glacialis C. hyperboreus relation conditions, based historical (1993–1998) (2007–2016) collections satellite‐based observations. We found strong correlations between...
A high resolution coastal and ocean hydrodynamic model system was used to investigate the transport deposition patterns of Particulate Organic Matter (POM) from kelp farmed at three locations different properties: a sheltered location, an exposed offshore location. Published values on sinking speeds organic particles were used, spanning several orders magnitude. Recent work quantifying release particulate matter link carbon possible cultivation volumes scenarios, finally this potential for...
Abstract Efficient sampling of coastal ocean processes, especially mechanisms such as upwelling and internal waves their influence on primary production, is critical for understanding our changing oceans. Coupling robotic with models provides an effective approach to adaptively sample features. We present methods that capitalize information from in situ measurements, using Gaussian process modeling objective functions, allowing efforts be concentrated regions high scientific interest....
Northwards flowing Atlantic waters transport heat, nutrients, and organic carbon in the form of zooplankton into eastern Greenland Sea Fram Strait. Less is known contribution phytoplankton advection this current, Water Inflow (AWI) spanning from North to Arctic Ocean. The situ advected primary production was estimated by using physical-biological coupled SINMOD model, northern Norway coast (along Norwegian Current, NAC), West Spitsbergen Current (WSC) entrance Ocean simulation results show...
The northern Svalbard shelf region is part of the Atlantic advective contiguous domain along which nutrients, phyto- and mesozooplankton are advected with Water from Norwegian Sea bream into Arctic Ocean. By applying SINMOD model we investigated how much region. We also compare this supply local production. To achieve this, selected a box north calculated in- outflux Calanus finmarchicus C. glacialis. average biomass inside ranged between 0.5 to 3.0 g C m-2 in March August, respectively....
Antarctic krill ( Euphasia superba ) are a key component in the Southern Ocean ecosystem, especially Atlantic sector, where majority of population is concentrated. The Norwegian commercial fishery exclusively targets three subareas Antarctic: western Peninsula, and northern shelves both South Orkney Islands Georgia. Given it's reliance on oceanic transport from other regions potential impact rising sea temperatures habitat, Georgian particularly sensitive to altering environmental...
Continuous sampling and analysis of data from the Atlantic sector Southern Ocean is key to monitoring rapid, stochastic ecosystem changes in region. Antarctic krill (hereafter krill), subject this research, particularly prone regional warming, with a southward contraction its habitat forecast. While coastal regions Peninsula, South Orkney Islands Georgia are relatively well surveyed using trawl acoustic survey methods, offshore environments represent significant gaps. Many important stages...
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 32 m horizontal resolution were run for periods up 650 days 3 sites different oceanographic characteristics: one fjord location, medium-exposed location influenced by water and coastal location. Records on feed each cage at converted feces released based a published mass balance model. The...
