Deep water cycle studies have largely focused on subduction of lithosphere formed at fast spreading ridges. However, oceanic plates are more likely to become hydrated as spreading rate decreases.

Variable water input controls evolution of the Lesser Antilles volcanic arc
Combined geochemical and geophysical data indicate that the structure and hydration of the subducted plate are directly connected to the evolution of the arc and its associated seismic and volcanic hazards.
Widespread Hydration of the Back Arc and the Link to Variable Hydration of the Incoming Plate in the Lesser Antilles From Rayleigh Wave Imaging
Subduction zone dynamics are important for a better understanding of natural hazards, plate tectonics, and the evolution of the planet. Despite this, the factors dictating the location and style of
Variation in Upper Plate Crustal and Lithospheric Mantle Structure in the Greater and Lesser Antilles From Ambient Noise Tomography
The crust and upper mantle structure of the Greater and Lesser Antilles Arc provides insights into key subduction zone processes in a unique region of slow convergence of old slow‐spreading oceanic
Subduction history of the Caribbean from upper-mantle seismic imaging and plate reconstruction
Teleseismic P-wave imaging of the eastern Caribbean upper mantle is improved and identified subducted-plate fragments are compared with trench locations predicted from plate reconstruction, showing that material at 700–1200 km depth below South America derives from 90–115 Myr old westward subduction, initiated prior to Caribbean Large-Igneous-Province volcanism.
Along‐Arc Heterogeneity in Local Seismicity across the Lesser Antilles Subduction Zone from a Dense Ocean‐Bottom Seismometer Network
The Lesser Antilles arc is only one of two subduction zones where slow‐spreading Atlantic lithosphere is consumed. Slow‐spreading may result in the Atlantic lithosphere being more pervasively and


Dehydration of subducting slow-spread oceanic lithosphere in the Lesser Antilles
Joint active-source/local-earthquake seismic tomography is used to derive unprecedented constraints on multi-stage fluid release from subducting slow-spread oceanic lithosphere, suggesting that serpentinized peridotite exhumed in tectonized slow- spread crust near fracture zones may increase water transport to sub-arc depths.
Water, oceanic fracture zones and the lubrication of subducting plate boundaries-insights from seismicity
We investigate the relationship between subduction processes and related seismicity for the Lesser Antilles Arc using the Gutenberg–Richter law. This power law describes the earthquake-magnitude
