Current Research
Hey: Analysis of data from
recent oceanographic expeditions:
a) Tectonic/volcanic segmentation
and controls on hydrothermal
venting along Earth's fastest seafloor spreading system, EPR
27°-32°S
b) ALVIN magnetometer investigations of tectonic windows into
superfast spread crust exposed at Pito Deep, Easter Microplate
c) Origin of the V-shaped ridges along the Reykjanes Ridge south
of Iceland (see Fig.)
Current Research (Cont.)
Martinez: Major NSF initiatives such as the Ridge2000 Program
have decadal time spans with goals
of investigating a broad range of
interrelated processes at seafloor
spreading centers from mantle processes to the magmatic and tectonic
construction of the oceanic crust to
the biological systems that live in
these settings. Hydrothermal activity
is a key process that transfers matter
and energy across these components.
My recent work has focused on the
study of the geologic and geophysical
controls on the occurrence and distribution of hydrothermal activity at backarc spreading centers.
Evolution of mantle

Current Research
(Cont.)
Fryer: Divergent (MidAtlantic Ridge IODP Exp 305
and Mariana Backarc Basin)
and convergent plate margin
processes, (Mariana forearc)
petrogenesis and metamorphism
of the mantle, changing stress
regimes in subduction zones.
Recently funded to examine
dredged serpentinized peridotite
samples from numerous forearc
sites to study evolution of the
suprasubduction-zone mantle.

Current Research (Cont.):
Kroenke: plate tectonic reconstruction of the Pacific, initiation of
subduction, hot-spot mapping. Reconciling late Neogene Pacific
absolute and relative plate motion change.
Wessel et al., 2006: Geometry of the Hawaii-Emperor seamount chain. The Hawaii-Emperor Bend
dated at 47–48 Myr (~Chron 21) by allowing 1–2 Myr for edifice construction. Triangles = recent dates
from Sharp and Clague [2002] except for Nintoku [Tarduno et al., 2003].
Future Directions
Hey: in addition to continuing my research in the 3 areas mentioned
above, I'm revising the Cox and Hart textbook, Plate Tectonics:
How it Works.
Martinez: Studies of several (Lau, Manus and Mariana) backarc
basins reveal a broad range of conditions of back-arc basin
development. His work has attracted attention from major mining
companies (Teck Cominco, Nautilus Minerals - currently funding
my research though sizable gifts (~$700K) I hope to continue and
expand this academic/industry relationship in the future.
Kroenke: Will expand recent studies to include examination of
global tectonism, cause and effect.
Future Directions (Cont.):
Fryer: Studies of arc/backarc basin volcanism has been carried out
recently in collaboration with Japanese colleagues (Shinkai 6500
diving and dredging cruises). Studies of origin of island arc crust
will continue also with Shinkai 6500 dives. Recently funded
studies of effects of in situ Archeal communities on peridotitic
substrates will be carried out at ODP Seafloor Observatory Site
1200. I will be Co-chief Scientist and first user of WHOI HROV in
the Mariana Trench (2009). A recently funded study of the
evolution and regional variability of forearc mantle will use
dredged samples of serpentinized peridotites from the Mariana
forearc (analysis to include thermal IR, mineralogy, micro-Raman
mapping, EBSD analysis, velocity measurements). I am principal
proponent (approached to be Co-chief Scientist) of IODP drilling
expedition to Mariana region in 2009 (scheduled/funding
permitting).
