Nitrogen
Isotope (BioGeo)chemistry (OPPORTUNITIES
FOR NEW GRADUATE STUDENTS)
- analytical methods (experimentation with carrier gas
methods; Bebout et al., 2007, Chemical
Geology)
- field applications (cyclosilicates, eclogites, behavior during
partial melting,
fluid-mineral fractionation; incorporation
during microbial chemical
alteration
of seafloor basalts)
- preservation of N biogeochemical
signatures in ancient sedimentary (collaborative with Linda Godfrey,
Rutgers
University)
- records of deep N subduction in HP and UHP
metabasaltic suites (collaborative with Ralf Halama, Universität
Kiel;
Timm John, Universität
Münster;
Maureen Feineman, Penn. State University)

We
have recently
analyzed
C-N
concentrations and isotopic
compositions
of sediment
[and altered seafloor
basalt] recovered on ODP Legs 185
and 205 [see
Sadofsky and Bebout, 2004, G-cubed;
Li and Bebout, 2005, JGR
and ODP Leg
205 Scientific Results),
with the goals of characterizing organic sources and
diagenetic history
and subduction input fluxes in
the Izu-Bonin-Mariana
and Central American convergent
margins. Locations for
ODP Sites 1149, 801, and also the
ongoing NanTroSEIZE project (in which we are also involved), are
shown on
the
seafloor topographic map
above (image above is from Smith

Topography,
