The Nordic Seas circulation and exchanges.
The Nordic Seas provide the main oceanic connection between the Arctic and the deep global oceans via dense overflows between Greenland and Scotland, into the North Atlantic. An understanding of the circulation and exchanges of this region is vital for any consideration of the implications of high …

statistical analysis of acoustic transmission scintillation in the 2014 Nordic Seas Experiment
… properties. In February 2014, the 2014 Nordic Seas Experiment was conducted in Norway, in which acoustic broadband signals were transmitted and received frequently, propagating through a waveguide on the continental shelf, and large sets of acoustic data were gathered. The work presented …

Tracking and speed evaluation of cod schools in the 2014 Nordic Seas experiments
… Sensing system (OAWRS) was employed in the Nordic Seas for the study of fish shoal behavior in that region. The OAWRS system enables the study of multiple shoals simultaneously over long periods. The experiment took place in three main spawning areas on the shores of Norway, and lasted from …

Gradients in benthic community structure and bioturbation potential along the Nordic Seas continental margin
The Nordic Seas region, extending north from the Wyville-Thomson Ridge, west of Scotland to the Fram Strait, north of Svalbard, marks a transitional zone between the temperate North Atlantic Ocean and the polar Arctic Ocean. The influence of contrasting fluxes of organic matter on benthic community …

A study of the large scale circulation and water mass formation in the Nordic seas and Arctic Ocean
… that the dense overflows show little or no seasonal or interannual variability. An inverse box model has been constructed that shows that the new circulation scheme is consistent with conservation statements for mass, heat and salt as well. According to the new circulation scheme the major …

Meltwater injections and their impact on Atlantic meridional overturning circulation and climate during the time period of Heinrich Event 1 and the last deglaciation
… are<br/>combined with previous studies from the Nordic seas and the ‘Ice Rafted Debris<br/>(IRD) belt’, and portray a sequence of events through the interval of H1. These<br/>events progressed from an onset of meltwater release around 19 ka BP, through<br/>the ‘conventional’ H1 phase from ~17.5 …

Hydrographic structure of overflow water passing through the Denmark Strait
… is transferred from the upstream basins in the Nordic Seas, across the Greenland-Scotland Ridge, and to the North Atlantic Ocean. The goal of this study is to characterize the hydrographic structure of the different DSOW constituents at the sill before the water descends into the Irminger Sea …

Tracing past and present Arctic geochemical cycling and its link to climate change using neodymium isotopes
… in deep water sourcing and formation in the Nordic Seas from the last glacial to modern. During the Last Glacial Maximum, εNd in the Nordic Seas is found to have a similar homogeneity to the late Holocene and modern, suggesting similar advective circulation during both periods. Heterogeneous …

Instantaneous continental-shelf scale sensing of cod with Ocean Acoustic Waveguide Remote Sensing (OAWRS)
… cod with OAWRS over ecosystem scales in the Nordic Seas. Following direct requests by Massachusetts state officials to determine if OAWRS could be used to detect and survey the reported waning cod populations in coastal New England waters, we obtained measurements of typical aggregation …

The origins of the East Greenland Coastal Current on the Northeast Greenland Shelf: a comparison of two reanalysis products
… along the East Greenland Shelf and into the Nordic Seas and subpolar North Atlantic. How this fresh water initially flows onto the Northeast Greenland Shelf (NEGS) and feeds the EGCC is not well known due in part to the lack of observations in the region. In this thesis, I use two ocean …

A study of North Atlantic ventilation using transient tracers
… and 3He inflow to the abyssal Atlantic from the Nordic Seas is developed. The 3H and 3He distributions in the abyssal North Atlantic and Deep Western Boundary Current (DWBC) are also presented. A simple model of abyssal circulation is constructed using the model Nordic Seas overflow curves, the …

Strong wind events across Greenland’s coast and their influence on the ice sheet, sea ice and ocean
… adjacent to the subpolar North Atlantic and Nordic Seas is characterized by a large land-sea temperature contrast. Therefore, winds across the coast advect air across a horizontal temperature gradient and can result in significant surface heat fluxes both over the ice sheet (during onshore …

Moored observations of shelfbreak processes at the inflow to and outflow from the Arctic Ocean
