Long-Term Statistics of Observed Bubble Depth Versus Modeled Wave Dissipation
Strand, Kjersti Opstad; Breivik, Øyvind; Pedersen, Geir; Vikebø, Frode Bendiksen; Sundby, Svein; Christensen, Kai Håkon (Journal article; Peer reviewed, 2020)Air bubble penetration depths are investigated with a bottom‐mounted echosounder at a seabed observatory in northern Norway. We compare a 1‐year time series of observed bubble depth against modeled and estimated turbulent ... -
The Northeast Greenland shelf as a potential habitat for the Northeast Arctic cod
Strand, Kjersti Opstad; Sundby, Svein; Albretsen, Jon; Vikebø, Frode Bendiksen (Peer reviewed; Journal article, 2017-09-26)Observations (1978–1991) of distributions of pelagic juvenile Northeast Arctic cod (Gadus morhua L.) show that up to 1/3 of the year class are dispersed off the continental shelf and into the deep Norwegian Sea while on ... -
Retention of Coastal Cod Eggs in a Fjord Caused by Interactions between Egg Buoyancy and Circulation Pattern
Myksvoll, Mari Skuggedal; Sundby, Svein; Ådlandsvik, Bjørn; Vikebø, Frode B. (Peer reviewed; Journal article, 2011-08-01)Norwegian coastal cod form a stationary population of Atlantic cod Gadus morhua consisting of several genetically separated subpopulations. A small-scale differentiation in marine populations with pelagic eggs and larvae ... -
Sub-surface maxima in buoyant fish eggs indicate vertical velocity shear and spatially limited spawning grounds
Strand, Kjersti Opstad; Vikebø, Frode; Sundby, Svein; Sperrevik, Ann Kristin (Peer reviewed; Journal article, 2018)Observed vertical profiles of buoyant particles, in this case pelagic Northeast Arctic cod eggs, occasionally deviate from the vertical diffusion-buoyancy balance by displaying sub-surface maxima. Here we present a mechanism ... -

Strand, Kjersti Opstad; Vikebø, Frode Bendiksen; Sundby, Svein; Sperrevik, Ann Kristin; Breivik, Øyvind (Peer reviewed; Journal article, 2019-05)Observed vertical profiles of buoyant particles, in this case pelagic Northeast Arctic (NEA) cod eggs, occasionally deviate from the vertical diffusion‐buoyancy balance by displaying subsurface maxima. Here, we present a ... -
Wind Intensity Is Key to Phytoplankton Spring Bloom Under Climate Change
Vikebø, Frode Bendiksen; Strand, Kjersti Opstad; Sundby, Svein (Peer reviewed; Journal article, 2019-08-30)The onset of the spring bloom (OSB) occurs when phytoplankton growth exceeds losses and is promoted by a transition from deep convection to a shallow mixing layer concurrent with increasing light intensities in nutrient-enriched ...
