My research as a marine geophysicist has focused primarily
on the mid-ocean ridge, the most active geologic feature
on the planet, using whatever geophysical or geological tools
I could employ to study the tectonics of this complex system.
Some the areas I see as promising for future research include:
the fundamental segmentation of mid-ocean ridges and
the significance of ridge-axis discontinuities including
overlapping spreading centers to the creation of oceanic crust,
the processes responsible for the creation and deformation
of oceanic crust particularly through the study of
marine magnetic anomalies and quantitative geomorphology,
and the importance of hydrothermal vent systems
to the heat balance of the ridge. So much is still not known
that I look forward to many more exciting discoveries and insights
in the future as we continue to explore the mid-ocean ridge.
The mid-ocean ridge offers extraordinary opportunities
for interdisciplinary research. The supply of magma to the ridge
controls the geochemistry of erupted lavas, the magnetization
of the crust and the location of seafloor hydrothermal systems;
which in turn control the distribution of exotic benthic
faunal communities. For example, if one plots the occurrence
of hydrothermal vents versus axial depth, cross-sectional area
or even crustal magnetization, there is an excellent correlation!
These linkages provide rich opportunities for cross-disciplinary
research.
