Plastic pollution is now pervasive in the Arctic, even in areas with no apparent human
activity, such as the deep seafloor. In this Review, we describe the sources and impacts of …

The Arctic Monitoring and Assessment Programme has published a plan and guidelines for
the monitoring of litter and microplastics (MP) in the Arctic. Here, we look beyond …

The increased global production of plastics has been mirrored by greater accumulations of
plastic litter in marine environments worldwide. Global plastic litter estimates based on field …

We explore dense water cascading (DWC), a type of bottom‐trapped gravity current, on
multidecadal time scales using a pan‐Arctic regional ocean‐ice model. DWC is particularly …

Accurately representing coastal and shelf seas in global ocean models represents one of
the grand challenges of Earth system science. They are regions of immense societal …

When a gravity current reaches the level of neutral buoyancy in a stratified water body it can
separate from the sloping boundary as an intrusion. If there is a density gradient within the …

Kveithola is a glacially-carved, EW trending trough located in the NW Barents Sea, an
epicontinental shelf sea of the Arctic Ocean located off northern Norway and Russia. A set of …

A multi-envelope generalised coordinate system for numerical ocean modelling is
introduced. In this system, computational levels are curved and adjusted to multiple 'virtual …

In response to an increasing demand for bespoke or tailored regional ocean modelling
configurations, we outline fundamental principles and practices that can expedite the …

Abstract The North Icelandic Jet (NIJ) is the densest component of the Denmark Strait
Overflow Water, feeding the abyssal limb of the Atlantic Meridional Overturning Circulation …
