Generation of Vorticity Near Topography: Anticyclones in the Caribbean Sea

van der Boog, C.G. (author), Molemaker, M. J. (author), Dijkstra, H. A. (author), Pietrzak, J.D. (author), Katsman, C.A. (author)

Mesoscale anticyclonic eddies dominate the sea-surface height variability in the Caribbean Sea. Although it is well established that these anticyclones are formed near the eastern boundary of the Caribbean Sea, which is demarcated by the Lesser Antilles, the source of their anticyclonic vorticity remains unclear. To gain insight into this...

Spatial Variations of Antarctic Intermediate Water in the Caribbean Sea Due To Vertical Mixing Along Its Path

van der Boog, C.G. (author), Dijkstra, Henk A. (author), Pietrzak, J.D. (author), Katsman, C.A. (author)

Because of its pronounced fresh signature, the properties of the northward-flowing Antarctic Intermediate Water (AAIW) affect the Atlantic Meridional Overturning Circulation. Hence, understanding modifications of AAIW along its path is important. Here, we analyze AAIW changes along its path in the Caribbean Sea and assess whether vertical...

Direct and Indirect Pathways of Convected Water Masses and Their impacts on the Overturning Dynamics of the Labrador Sea

Georgiou, S. (author), Ypma, S.L. (author), Brüggemann, N. (author), Sayol España, J.M. (author), van der Boog, C.G. (author), Spence, P. (author), Pietrzak, J.D. (author), Katsman, C.A. (author)

The dense waters formed by wintertime convection in the Labrador Sea play a key role in setting the properties of the deep Atlantic Ocean. To understand how variability in their production might affect the Atlantic Meridional Overturning Circulation (AMOC) variability, it is essential to determine pathways and associated timescales of their...

Global dataset of thermohaline staircases obtained from Argo floats and Ice-Tethered Profilers

van der Boog, C.G. (author), Koetsier, J.O. (author), Dijkstra, Henk A. (author), Pietrzak, J.D. (author), Katsman, C.A. (author)

Thermohaline staircases are associated with double-diffusive mixing. They are characterized by stepped structures consisting of mixed layers of typically tens of metres thick that are separated by much thinner interfaces. Through these interfaces enhanced diapycnal salt and heat transport take place. In this study, we present a global dataset...

Tropical Biogeomorphic Seagrass Landscapes for Coastal Protection: Persistence and Wave Attenuation During Major Storms Events

James, R.K. (author), Lynch, A. (author), Herman, P.M.J. (author), van Katwijk, M.M. (author), van Tussenbroek, B.I. (author), Dijkstra, H.A. (author), van Westen, R. M. (author), van der Boog, C.G. (author), Klees, R. (author), Pietrzak, J.D. (author), Slobbe, D.C. (author), Bouma, T.J. (author)

The intensity of major storm events generated within the Atlantic Basin is projected to rise with the warming of the oceans, which is likely to exacerbate coastal erosion. Nature-based flood defence has been proposed as a sustainable and effective solution to protect coastlines. However, the ability of natural ecosystems to withstand major...

The potential of coastal ecosystems to mitigate the impact of sea-level rise in shallow tropical bays

Keyzer, L.M. (author), Herman, P.M.J. (author), Smits, B.P. (author), Pietrzak, J.D. (author), James, R.K. (author), Candy, A.S. (author), Riva, R.E.M. (author), Bouma, T.J.

Shallow tropical bays in the Caribbean, like Orient Bay and Galion Bay in Saint Martin, are often sheltered by coral reefs. In the relatively calm environment behind the reefs, seagrass meadows grow. Together, these ecosystems provide valuable ecosystem services like coastal protection, biodiversity hotspots, nursery grounds for animals and...

Sea-level rise poses severe threats to coastal and low-lying regions around the world, by exacerbating coastal erosion and flooding. Adequate sea-level projections over the next decades are important for both decision making and for the development of successful adaptation strategies in these coastal and low-lying regions to climate change....

Tropical beaches provide coastal flood protection, income from tourism, and habitat for flagship species. They urgently need protection from erosion, which is being exacerbated by changing climate and coastal development. Traditional coastal engineering solutions are expensive, provide unstable temporary solutions, and often disrupt natural...

Haakman, Koen (author), Sayol España, J.M. (author), van der Boog, C.G. (author), Katsman, C.A. (author)

This work quantifies the magnitude, spatial structure, and temporal evolution of the cold wake left by North Atlantic hurricanes. To this end we composited the sea surface temperature anomalies (SSTA) induced by hurricane observations from 2002 to 2018 derived from the international best track archive for climate stewardship (IBTrACS). Cold wake...

The impact of upwelling on the intensification of anticyclonic ocean eddies in the Caribbean Sea

van der Boog, C.G. (author), Pietrzak, J.D. (author), Dijkstra, Henk A. (author), Brüggemann, N. (author), Van Westen, René M. (author), James, Rebecca K. (author), Bouma, Tjeerd J. (author), Riva, R.E.M. (author), Slobbe, D.C. (author), Klees, R. (author), Zijlema, Marcel (author), Katsman, C.A. (author)

The mesoscale variability in the Caribbean Sea is dominated by anticyclonic eddies that are formed in the eastern part of the basin. These anticyclones intensify on their path westward while they pass the coastal upwelling region along the Venezuelan and Colombian coast. In this study, we used a regional model to show that this westward...

In this study, an idealized eddy-resolving model is employed to examine the interplay between the downwelling, ocean convection and mesoscale eddies in the Labrador Sea and the spreading of dense water masses. The model output demonstrates a good agreement with observations with regard to the eddy field and convection characteristics. It also...

In the Caribbean Sea, mesoscale anticyclonic ocean eddies impact the local ecosystem by mixing of low salinity river outflow with the nutrient-rich waters upwelling along the Venezuelan and Colombian coast. To gain insight into the physics and the ecological impact of these anticyclones, we performed a combined hydrographic and biological...

Mechanisms of the 40–70 Day Variability in the Yucatan Channel Volume Transport

van Westen, René M. (author), Dijkstra, Henk A. (author), Klees, R. (author), Riva, R.E.M. (author), Slobbe, D.C. (author), van der Boog, C.G. (author), Katsman, C.A. (author), Candy, A.S.

The Yucatan Channel connects the Caribbean Sea with the Gulf of Mexico and is the main outflow region of the Caribbean Sea. Moorings in the Yucatan Channel show high-frequent variability in kinetic energy (50–100 days) and transport (20–40 days), but the physical mechanisms controlling this variability are poorly understood. In this study, we...
