Talk abstract:

This presentation will focus on observations, processes and variability in the Labrador Sea and various aspects of oceanic seasonality, especially with respect to interpreting shipboard observations and making conclusions about longer-term changes in the upper ocean and below. The present chapter of the North Atlantic series includes the Labrador Sea’s World Ocean Circulation Experiment (WOCE) line climatology, trends and multiyear cycles of convectively-formed water mass developments, approached with the…

Talk Abstract:

The ocean transports vast quantities of dispersed material such as sediment, plankton, microplastics, oil droplets, bubbles and more. At the ocean surface, gravity waves transport mass through a process referred to as Stokes drift. Finite-sized particles of arbitrary shape exhibit additional Stokes drift-like phenomena that can alter their transport. In this talk, I explore the effects of particle inertia and shape on particle behavior in waves. I demonstrate both an angular analogue of Stokes drift for non-spherical particles and a vertical Stokes drift for…

Talk Abstract:

The global meridional overturning circulation is key to climate through its role transporting and storing tracers such as heat and carbon. Climate models suggest that the circulation is changing but the physical drivers are poorly constrained. Here an explicitly transparent machine learning method, Tracking global Heating with Ocean Regimes (THOR), reveals the root mechanisms and assesses changes across a range of climate models. Addressing the fundamental question of the existence of dynamical coherent regions, these are identified and used to understand…

Talk Abstract:

Submesoscale processes provide a pathway for energy to transfer from the balanced circulation to turbulent dissipation. One class of submesoscale phenomena that has been shown to be quite effective at mixing and removing energy from the balanced flow are centrifugal-symmetric instabilities (CSIs), which have been observed to generate significant mixing in both the surface boundary layer and bottom boundary layer flows along bathymetry, where they have been implicated in the mixing and watermass transformation of Antarctic Bottom…
