	abstract = {Climatic changes have decreased the stability of the Gulf Stream (GS), increasing the frequency at which its meanders interact with the Mid-Atlantic Bight (MAB) continental shelf and slope region. These intrusions are thought to suppress biological productivity by transporting low-nutrient water to the otherwise productive shelf edge region. Here we present evidence of widespread, anomalously intense subsurface diatom hotspots in the MAB slope sea that likely resulted from a GS intrusion in July 2019. The hotspots (at \~{}50 m) were associated with water mass properties characteristic of GS water (\~{}100 m); it is probable that the hotspots resulted from the upwelling of GS water during its transport into the slope sea, likely by a GS meander directly intruding onto the continental slope east of where the hotspots were observed. Further work is required to unravel how increasingly frequent direct GS intrusions could influence MAB marine ecosystems.},

	abstract = {This work studies the subduction of the shelf water along the onshore edge of a warm-core ring that impinges on the edge of the Mid-Atlantic Bight continental shelf. The dynamical analysis is based on observations by satellites and from the Ocean Observatories Initiative Pioneer Array observatory as well as idealized numerical model simulations. They together show that frontogenesis-induced submesoscale frontal subduction with order-one Rossby and Froude numbers occurs on the onshore edge of the ring. The subduction flow results from the onshore migration of the warm-core ring that intensifies the density front on the interface of the ring and shelf waters. The subduction is a part of the cross-front secondary circulation trying to relax the intensifying density front. The dramatically different physical and biogeochemical properties of the ring and shelf waters provide a great opportunity to visualize the subduction phenomenon. Entrained by the ring-edge current, the subducted shelf water is subsequently transported offshore below a surface layer of ring water and alongside of the surface-visible shelf-water streamer. It explains the historical observations of isolated subsurface packets of shelf water along the ring periphery in the slope sea. Model-based estimate suggests that this type of subduction-associated subsurface cross-shelfbreak transport of the shelf water could be substantial relative to other major forms of shelfbreak water exchange. This study also proposes that outward spreading of the ring-edge front by the frontal subduction may facilitate entrainment of the shelf water by the ring-edge current and enhances the shelf-water streamer transport at the shelf edge.},
