    Chemistry in the Garden (2007)
    Cambridge : Royal Society of Chemistry
    Details Availability
    Description / Table of Contents: This book will make fascinating reading for the chemist with an interest in gardening as well as the gardener with a general interest in the scientific processes involved in the garden, The aim of this book is to describe some aspects of the chemistry and chemical ecology which are found in the garden. In the garden there are numerous interactions between plants, the soil and with other organisms in which chemistry plays a central mediating role. The discussion concerns several of the chemically and ecologically interesting compounds that are produced by common ornamental garden plants and vegetables and by the predators that attack them. Many chemists are amateur gardeners and this book is directed at them as well as those with a general interest in the scientific processes involved in the garden

    Seismic structure and segmentation of the axial valley of the Mid-Cayman Spreading Center (2017)
    AGU (American Geophysical Union) | Wiley
    In:  Geochemistry, Geophysics, Geosystems, 18 (6). pp. 2149-2161.
    Details
    Publication Date: 2020-02-06
    Description: We report the results of a two-dimensional tomographic inversion of marine seismic refraction data from an array of ocean-bottom seismographs (OBSs), which produced an image of the crustal structure along the axial valley of the ultraslow spreading Mid-Cayman Spreading Center (MCSC). The seismic velocity model shows variations in the thickness and properties of the young oceanic crust that are consistent with the existence of two magmatic-tectonic segments along the 110 km long spreading center. Seismic wave speeds are consistent with exhumed mantle at the boundary between these two segments, but changes in the vertical gradient of seismic velocity suggest that volcanic crust occupies most of the axial valley seafloor along the seismic transect. The two spreading segments both have a low-velocity zone (LVZ) several kilometers beneath the seafloor, which may indicate the presence of shallow melt. However, the northern segment also has low seismic velocities (3 km/s) in a thick upper crustal layer (1.5–2.0 km), which we interpret as an extrusive volcanic section with high porosity and permeability. This segment hosts the Beebe vent field, the deepest known high-temperature black smoker hydrothermal vent system. In contrast, the southern spreading segment has seismic velocities as high as 4.0 km/s near the seafloor. We suggest that the porosity and permeability of the volcanic crust in the southern segment are much lower, thus limiting deep seawater penetration and hydrothermal recharge. This may explain why no hydrothermal vent system has been found in the southern half of the MCSC.

    Magmatic-tectonic conditions for hydrothermal venting on an ultraslow-spread oceanic core complex (2017)
    GSA, Geological Society of America
    In:  Geology, 45 (9). pp. 839-842.
    Details
    Publication Date: 2020-02-06
    Description: Hydrothermal venting, an important cooling mechanism of the Earth, supports a diverse array of seafloor and sub-seafloor ecosystems that are sustained by large thermal and chemical fluxes. Vents have been found along even the slowest and coldest spreading centers, calling into question the driving heat source for these vents. The ultraslow-spreading Mid-Cayman Spreading Center in the Caribbean Sea, which hosts the axial-flank Von Damm Vent Field (VDVF), provides an opportunity to probe the mechanisms for venting at ultraslow spreading rates. Using active-source seismic data from the 2015 CaySeis (Cayman Seismic) experiment, we determined the seismic velocities in the large massif beneath the VDVF. We propose that this massif was produced by a pulse of on-axis magmatism at ca.2 Ma, which was then followed by exhumation, cooling, and fracturing. A low seismic velocity anomaly 5 km below the VDVF is evidence for either a cracking front mining lithospheric heat or intrusive magmatic sills, both of which could drive ongoing deep hydrothermal fluid circulation. We conclude that the transient magmatism and variable crustal thickness at ultraslow-spreading centers create conditions for long-lived hydrothermal venting that may be widespread, and other VDVF-like vents may be common in these areas.

    What’s rate got to do with it?: Oceanic core complex evolution and serpentinized mantle exhumation at the Mid-Cayman Spreading Center (2018)
    In:  [Invited talk] In: AGU Fall Meeting 2018, 10.-14.12.2018, Washington, D.C., USA .

    Description: The world’s slow and ultraslow spreading centers host oceanic core complexes and exhume extensive tracts of mantle to the seafloor. Oceanic core complexes (OCCs) are several km-high, detachment-fault-bounded massifs of lower crust and upper mantle materials and appear to form when magmatic accretion and tectonic stretching are somewhat proportional. Mantle exhumation at ultraslow spreading rates may be due to passive upwelling leading to a thicker lithospheric lid, lower mantle potential temperature, and an anomalously thin oceanic crust. The ultraslow spreading (~15 mm/yr full rate) Mid-Cayman Spreading Center (MCSC) poses some interesting challenges to these global relationships. The spreading center itself is in some ways similar to slow-spreading (〉20 mm/yr) centers, and especially the Mid-Atlantic Ridge (MAR): faulting and magmatic intrusion are “killing” the Cayman OCCs in one place causing hydrothermal venting, basalts have similar Mg# compositions to those along the MAR, and seismicity also defines a relatively shallow (〈6-10 km) brittle-ductile transition. Yet, the MCSC has some conspicuous differences from slow spreading centers: axial bathymetry is far deeper, from 〉6 km in the deep areas of the rift and ~2.5 km on the OCC summit, crustal thickness is thin, 〈3 km away from OCCs and ~5 km within them, and incompatible element concentrations in basalt are consistent with low mantle potential temperature. As Cayman OCCs were spread off the MCSC axis they were dismembered by normal faults forming curvilinear scarps, and OCCs formed in the same overall positions as the previous one as the “footwall domain” persistently spread to the west. Most remarkably, there is an apparent increase in the amount of exhumed serpentinized mantle across a ~10-Ma isochron without any significant change in spreading rate. The Cayman Trough thus illustrates that spreading rate alone does not govern many of the characteristics attributed to ultraslow spreading centers, and indeed no one petrological or structural model captures all of the heterogeneity exhibited in systems such as the Cayman Trough. Mantle heterogeneity, unexpected dynamics in asthenosphere-lithosphere relationships, and complicated crustal strain patterns all are significant controls on slower spreading MOR systems.
