Postdotoral opportunity in magmatism at tectonism at the Hawaiian Volcano Observatory (9/16/08)

Dear Colleagues,

Our apologies for duplicate postings of this announcement.

We would like to let you know about an exciting USGS Mendenhall
Postdoctoral Opportunity that may be of interest to students or postdocs.
The USGS, in collaboration with the University of Alabama, is seeking
applicants to conduct postdoctoral research on the magma plumbing system
of Kilauea volcano, which is currently experiencing an unprecedented
eruptive episode involving vents at both its summit and east rift zone.

The goal of the project is the development and implementation of
conceptually and physically realistic models of Kilauea's shallow magmatic
system that build on existing knowledge of the volcano and that
quantitatively predict the spatial and temporal patterns of recently
observed volcanic activity, seismicity, and deformation. We seek a
researcher who will develop innovative models that take advantage of the
vast archive of geophysical and geological data at Kilauea, and who will
employ new cutting-edge data streams, for example, PS InSAR, high-rate
GPS, gravity, or array seismology.

The Mendenhall program is an exceptional opportunity to conduct research
with the USGS and includes full salary and project funding for two years
(with a possible extension for two additional years). If you are
interested in more information about this project, please don?t hesitate
to contact any one of the project supervisors (listed below), and visit
both the Mendenhall Program website (http://geology.usgs.gov/postdoc/) as
well as the website for this specific research opportunity
(http://geology.usgs.gov/postdoc/2010/opps/opp31.html).

The application deadline for this opportunity is November 12, 2008. The
successful applicant will be expected to have completed their PhD and
start work at the Hawaiian Volcano Observatory in late 2009 or early 2010.

Many thanks,

AGU U09: Asthenosphere Session (9/3/08)

Dear Collagues,

We encourage you to participate in the multi-disciplinary session:
Different Views on One Asthenosphere" at the 2008 AGU fall meeting
in San Francisco.

We are very pleased to present as invited speakers

Karsten Bahr, University of Göttingen
Clint Conrad, University of Hawaii
Colleen Dalton, Boston University
Alberto Saal, Brown University

U09: Different Views on One Asthenosphere

It is generally accepted that the asthenosphere is a mechanically weak
region in the shallow mantle underneath the lithosphere. Even so, every
discipline has a different perspective on what the asthenosphere is. For
example, it has been termed the low (seismic) velocity zone and the
low-viscosity zone, and its unique properties have been attributed to
either mineral properties at relevant temperatures and pressures or to
the presence of melt and/or water.

While we have a good understanding of some of the asthenosphere's
properties and know of the importance of this thin layer as it
influences mantle flow, we are still seeking a unified picture that
includes independent constraints from all relevant disciplines.

In this session we will explore different views on the asthenosphere to
(1) identify first order characteristics (e.g. location, depth,
viscosity, seismic velocity, anisotropy, attenuation, electrical
conductivity, density, flow field, lateral variations) and (2) combine
observations to provide a forum to discuss a unified picture of the
asthenosphere.

Submission deadline is 10 September 2008. (You can submit at
http://submissions3.agu.org/submission/entrance.asp)

We look forward to learning about your recent work!

3 Fall AGU Session Announcements (8/14/08)

1. Session V14: High Field Strength Elements
2. Session U25: Integrated Geohazards along Continental Margins and
Plate Boundary Zones
3. Session T26: Microplate Geodynamics

---------------------------------------------------------------------------------------

1. Session V14 on High Field Strength Elements

Dear Colleagues,

We would like to call your attention to a special session at the 2008
AGU Fall Meeting relating to the cycling of high field strength elements
from subduction zones to the deep mantle and back to the surface in
mantle plumes. Session V14 "From Subduction Zones to Mantle Plumes:
High Field Strength Elements as Geochemical Tracers of Crustal
Recycling" is
intended to bring together a confluence of information provided by
experimental, dynamical and geochemical studies that helps to unravel
subduction zone processes, and ultimately detect the signatures of the
recycled materials in hotspot lavas. While the session will highlight
experimental and geochemical studies that utilize HFSE as tracers of
subduction zone processes and whole mantle recycling, presentation of
other geochemical indicators that help constrain these processes such as
Ni in olivine as a proxy for eclogite melting, radiogenic isotope (Os,
Sr, Nd, Pb, etc.) signatures for crustal recycling, noble gas and
volatile signatures for crustal melting beneath arcs and recycling into
hotspots, is very much encouraged.

We hope that you will consider submitting an abstract to this session.

Best regards,
Glenn Gaetani
Matt Jackson

V14: From Subduction Zones to Mantle Plumes: High Field Strength
Elements as Geochemical Tracers of Crustal Recycling

Large quantities of oceanic and continental crust are known to enter the
mantle at subduction zones, and some of this material may become
entrained in mantle upwellings, or plumes, imparting a geochemical
signature on hotspot lavas. However, following injection into the
mantle, the composition and fate of subduction zone-processed material
is little known, making the signatures associated with recycled oceanic
crust difficult unambiguously identify. This owes, in large part, to the
complex processes that operate in subduction zones, including phase
changes and dehydration or partial melting of the subducted oceanic
lithosphere. Many of the elements frequently used as geochemical tracers
for subduction are volatile and/or fluid mobile and appear to be largely
lost from the subducted lithosphere during dehydration and/or partial
melting. High field strength elements (HFSE), such as Ti, Zr, Hf, Nb,
and Ta, are thought to behave conservatively during subduction zone
processing, providing a unique tools for understanding subduction zone
processes and identifying recycling signatures in hotspot lavas. This
session is intended to bring together a confluence of information
provided by experimental, dynamical and geochemical studies that helps
to unravel subduction zone processes, and ultimately detect the
signatures of the recycled materials in hotspot lavas. While the session
will highlight experimental and geochemical studies that utilize HFSE as
tracers of subduction zone processes and whole mantle recycling,
presentation of other geochemical indicators that help constrain these
processes such as Ni in olivine as a proxy for eclogite melting,
radiogenic isotope (Os, Sr, Nd, Pb, etc.) signatures for crustal
recycling, noble gas and volatile signatures for crustal melting beneath
arcs and recycling into hotspots, is very much encouraged.

2. Session U25: Integrated Geohazards along Continental Margins and
Plate Boundary Zones

Dear colleagues -

We would like to bring your attention to the following AGU Union special
session that provides a unique opportunity to showcase your MARGINS and
related research, and its societal relevance. Please consider
submitting an abstract to this session.

*U25: Integrated Geohazards along Continental Margins and Plate Boundary
Zones*

An ancillary but significant product of investigations along continental
margins and plate boundary zones (e.g., through the NSF MARGINS Program,
ODP/IODP, and related programs) has been a broader, highly integrated
understanding of the scientific causes and resulting impacts of
geohazards. Examples include, but are not limited to, (1) rheologic and
structural controls on plate boundary seismogenesis and tsunamigenesis;
(2) stratigraphic, chemical, and geomechanical factors that promote
weakening and failure; (3) climatic, tectonic, and anthropogenic
influences on rates of sediment erosion, transport and deposition, and
impacts on our coastlines, and (4) explosive volcanism, and the role of
magma composition and volatile flux in eruptive behavior. Although
geologic settings may differ, they share many common processes and
conditions that contribute to hazardous phenomena; therefore a broad,
cross-disciplinary discussion could benefit many scientific
communities. To foster these discussions, we solicit contributions that
address the wide range of margin-related geologic hazards, their causes,
and their consequences. Field, laboratory, and numerical studies are
welcome.

3. Session T26: Microplate Geodynamics

Dear Colleague,

Suzanne Baldwin and I would like to encourage you to consider making a
presentation at a special session at AGU we are convening entitled
"Microplate Geodynamics". The detailed session information is listed
below. We ask that you share this email with students and colleagues who
may be interested. Please note that the AGU abstract deadline is
September 10, 2008 (23:59 Universal Time). For more information, please

Session #: T26 Title: Microplate Geodynamics Sponsor: Tectonophysics.
CoSponsors: Geodesy, Geomagnetism and Paleomagnetism, Seismology,
Volcanology, Geochemistry, and Petrology. Description: Microplates form
and evolve at convergent, transform, and divergent boundaries between
large lithospheric plates. These fault-bounded lithospheric fragments
preserve complex geologic and tectonic histories as they evolve over
relatively short spatial and temporal timescales, and rotate relative to
neighboring (micro)plates. Their evolution has important implications
for the recycling and exchange of material between crust and mantle,
terrane accretion, as well as the exhumation of high and
ultrahigh-pressure rocks. We invite contributions from the fields of
geodynamics, geophysics, geodesy, geology, geochemistry etc. that seek
to understand how microplates evolve in space and time, including
active, ancient or analog examples. Contributions that highlight
interdisciplinary approaches to the study of the four dimensional
evolution of microplates, including their formation, growth and
destruction, are especially encouraged.

Nankai Seismogenic Zone - AGU Session T-22 Announcement (8/14/08)

Colleagues,

Please consider submitting an abstract to the following special
session, organized to highlight all research related to the
seismogenic zone of the Nankai Trough subduction system.

SESSION T22: Plate Boundary Processes in the Nankai Trough
Subduction Zone

Conveners: Harold J. Tobin (Un. of Wisconsin, USA) and Masataka
Kinoshita (JAMSTEC-IFREE, Japan)

The Nankai Trough has become an iconic subduction zone for the
investigation of forearc tectonic processes and great subduction
earthquakes. It is perhaps the most intensively-studied
convergent plate boundary in the world. Recent work here ranges
from the discovery of deep, non-volcanic tremor and VLF
earthquakes, through detailed seismic tomography of subducting
plate and forearc wedge structure, high resolution 3D seismic
reflection surveys and, most recently, direct sampling through
scientific drilling. This multi-disciplinary session will
highlight the results of the just-completed first stage of IODP
drilling in the NanTroSEIZE project, as well as recent 3D
seismic reflection imaging, novel seismological observations,
and geodetic studies. Contributions are welcomed on any topic
related to the Nankai forearc and plate boundary processes,
including accretionary wedge architecture, state of stress,
fault zone structure, fluid-fault interaction, megathrust
earthquakes, tsunamigenesis, and tremor and VLF seismic events.

Session Announcement for AGU (8/6/08)

Dear colleagues,

We would like to encourage you to submit you latest research to the
session we organize at the next AGU in San Francisco (15-19 December
2008). We hope to bring together geochemists, petrologists,
geophysicists and all those interested by the subduction zones to
contribute to make the session a big success.

V06: Subduction Zones: Geochemical Processes and Geophysical Constraints
Sponsor: Volcanology, Geochemistry, and Petrology
CoSponsor: Mineral and Rock Physics, Seismology. Tectonophysics

Description: Subduction zones are one of the most geologically
dynamic and scientifically exciting areas of the earth because they are
the place where old crust is destroyed and new crustal material is
created. They also are responsible for most of the volcanoes and produce
most of the largest earthquakes and tsunamis. This session aims at
evaluating the geochemical processes and budgets of subduction zones and
the associated petrological processes. We welcome contributions focused
on (a) the chemical and isotopic budget of the subducted material (the
input sediments and crust), (b) the composition of the volcanic arcs,
back-arcs and fore-arc basins and their origins, (c) the effects of the
presence of volatiles on the melting conditions in the mantle wedge, (d)
the seismic and other geophysical characteristics of the materials of
the mantle wedge that constrain compositions and processes, and
establish mass transfer estimations and (e) physical and numerical
modeling of mass transfer in subduction channels and mantle wedge.
Integration of these different approaches should help our community to
decipher the complex processes occurring in key areas of our planet and
by consequence to better understand long-term contribution of subduction
processes to its evolution.

We hope to meet you soon in San Francisco!

Do not miss the deadline for submitting your abstract: 10 September 2008

The conveners: Catherine Chauvel, Bruno Reynard and Roy Hyndman

2 AGU Session Announcements (8/5/08)

1. Gulf of California - Salton Trough MARGINS Boundary System
2. Minerals, Inclusions and Volcanic Processes

----------------------------------------------------------------------------------------------------

1. Gulf of California - Salton Trough MARGINS Boundary System

AGU Session Announcement: Recent Advances in Understanding the Gulf of
California - Salton Trough Plate Boundary System: Along Strike and
Through Time

We would like to draw your attention to a special session at the Fall
AGU meeting that will examine the Gulf of California - Salton Trough
MARGINS focus site. We encourage submission of abstracts on recent
research and/or novel ideas from any relevant geoscience discipline, in
the terrestrial or marine realms, that contributes to understanding this
plate boundary over the past ~12 million years. Please share this
announcement with interested people who might not have received this
message.

SESSION T42: Recent Advances in Understanding the Gulf of California -
Salton Trough Plate Boundary System: Along Strike and Through Time

CONVENERS: Paul J. Umhoefer (paul.umhoefer at nau.edu), Michael Oskin
(oskin at geology.ucdavis.edu), Rebecca Dorsey (rdorsey at uoregon.edu), Joann
Stock (jstock at gps.caltech.edu)

DESCRIPTION: The Gulf of California - Salton Trough is an active
oblique-divergent plate boundary. Despite similar rates of relative
plate motion along strike, major differences in rifting style have been
expressed along the boundary and through time since 12 Ma. Many
parameters and processes along the plate boundary may have affected
rifting style, including strain partitioning, localization of strain,
width of rift domains, and the role of magmatism, low-angle normal
faults, and sediment flux in surface to upper mantle processes. The
Colorado River has produced a large sediment flux since 5 Ma that
dominates the north while the south is sediment-starved. The role of
varying climate and tectonics is an emerging research theme as the
boundary spans from temperate to tropical zones. The total offset across
the plate boundary and its temporal development is controversial. How
the northern part of the system in the Salton trough ties northward into
the broader Pacific - North America boundary is also incompletely
understood. This session welcomes contributions from recent research or
novel ideas from any relevant research, terrestrial or marine, that
contributes to understanding this plate boundary over the past 12
million years.

The last two decades have witnessed a dramatic growth in interest in
studies of melt inclusions, small portions of melt trapped by
crystals growing during magma evolution. One important area of
application for melt inclusion research is the study of primitive
mantle-derived magmas. These are commonly modified prior to eruption
by fractionation, degassing, assimilation and other processes, with
melt inclusions potentially providing snapshots of the early
crystallisation environment. Increasing interest in melt inclusions
has also stimulated theoretical, petrological and experimental
studies aimed at understanding the processes that lead to melt
inclusion trapping and post-entrapment modification. This session,
complementing the short-course for the new Reviews in Mineralogy and
Geochemistry volume Minerals, Inclusions and Volcanic Processes,
will focus on important and topical questions in the field of melt
inclusions research: What does the melt inclusion record actually
represent? How much is this record modified by post-entrapment
processes? What unique information is provided by melt inclusions?
How does this information tie in with broader topics in basaltic
petrogenesis? We welcome contributions based on studies of natural
samples and/or experimental and theoretical studies of melt inclusion
formation and modification.

Please forward this information to any interested students,colleagues or
other interested parties.

AGU session OS33: Coastal Geomorphology and Morphodynamics (7/31/08)

Greetings,
We wish to encourage submission of abstracts to the following AGU
session at The Fall Meeting in San Francisco (Dec 15-19). Abstracts
are due Sept 10.

OS33: Coastal Geomorphology and Morphodynamics

Coastal environments and landforms evolve in response to winds,
waves, tides, currents, sediment delivery, and relative sea level
fluctuations at a wide range of time and space scales. In light of
climate change-induced sea level rise, coastal geomorphology has
particular relevance to society because of the high density of human
population near the coast. This session welcomes contributions on
recent advances in coastal geomorphology and morphodynamics from a
variety of geomorphic settings (including rocky coasts, barrier
islands systems, open ocean coasts, sheltered/semi-enclosed bays,
uniform and mixed sediment beaches) at a variety of timescales
(event, seasonal, interannual through decadal, and century through
Quaternary), with particular emphasis on the feedbacks between
changes in morphology and forcing agents. Contributions based upon
field measurements, application and development of models, or
investigation of sedimentary deposits are encouraged.

Job Opportunities with USGS (7/29/08)

Dear colleague,
I want to bring to your attention our plan to advertise shortly for a
research scientist position in marine geology/geophysics at the USGS
Woods Hole Science Center. The center is located within the campus of
the Woods Hole Oceanographic Institution.
Please, follow the official announcement or contact me for details.

Separately we also seek a post-doctoral candidate to quantitatively
evaluate the tsunami hazard to the U.S. Gulf of Mexico and Atlantic
coasts. This two-year position, to start in October 2009, is part of the
USGS Mendenhall post-doctoral fellowship program. Details about the
program can be found at geology.usgs.gov/postdoc/. The official
announcement is attached.

Uri ten Brink (508) 457-2396, utenbrink@usgs.gov

Official annoucement for the Mendenhall post-doc:
2. Quantitative evaluation of tsunami hazard to the Gulf of Mexico
and Atlantic coasts

Tsunamis are among the world=92s most destructive coastal hazards. The
sharp increase in coastal population density, the intense development of
harbors and urban infrastructure, tourism, and the exploitation of
mineral resources in coastal areas, all set up a potential disaster of
catastrophic proportions. Although the frequency of tsunamis along the
Atlantic and Gulf of Mexico coasts of North America is low, tsunamis in
this region are a serious concern to policy makers and ordinary citizens
because of the dense infrastructure and population along the shoreline.
Major infrastructure projects, such as nuclear reactors, are designed
with consideration for a catastrophic event over a long time period
(10,000 years). Following the surge in application for licenses to build
new nuclear reactors along the Gulf and Atlantic Coasts, the USGS was
approached by the U.S. Nuclear Regulatory Commission to conduct research
that will help with the assessment of tsunami hazards to these coasts.

We seek a post-doctoral candidate to quantitatively evaluate the
tsunami hazard to the U.S. Gulf of Mexico and Atlantic coasts. The major
hazard to these coasts appears to arise from landslide-generated
tsunamis. The successful candidate will compile and analyze various data
including multibeam bathymetry, seismic reflection data, earthquake
data, and cores along the continental slope of the Gulf and Atlantic
coasts to evaluate and date the distribution of landslides in these
regions. The successful candidate will investigate theories and
observations regarding the effects of slide speed and bottom friction on
the amplitude of tsunamis and will use in-house software packages to
model the effects of potential landslide sources on selected coastal
segments of the Gulf and Atlantic coasts. The successful candidate is
expected to interact with the NOAA PMEL lab regarding modeling
techniques and with university scientists regarding landslide dynamics
to enhance the quality of their research. Postdoctoral candidates in the
fields of geophysics, geology (with a strong background in computer
simulations), or civil engineering are encouraged to apply. The
successful candidate will pursue their work both in Woods Hole, MA, and
Menlo Park, CA.

Tsunami research is a young and exciting interdisciplinary field that
bridges between geology, solid earth geophysics, seismology, civil
engineering, and hydrodynamics. In particular, little is known about
submarine landslides, their excitation by ground shaking, and the
coupling between landslide and the overlying water layer. The USGS is
emerging as a leader in this field because of its diverse expertise. The
successful candidate will promote USGS leadership in tsunami science.

Proposed Duty Station: Woods Hole, MA; Menlo Park, CA

Areas of Ph.D.: Geology, geophysics, engineering

Qualifications: Applicants must meet one of the following
qualifications: Research Geologist, Research Geophysicist, Research Engineer

(This type of research is performed by those who have backgrounds for
the occupations stated above. However, other titles may be applicable
depending on the applicant's background, education, and research
proposal. The final classification of the position will be made by the
Human Resources specialist.)

Central American Subduction System

Guest Editor(s): G. Alvarado, K. Hoernle, E. Silver

Description: This theme invites papers covering all disciplines and
aspects of the Central American Subduction System. Topics include (but
are not restricted to) the composition, age, structure, diagenetic,
metasomatic, and metamorphic reactions within the subduction input
(incoming and subducting plates) and processes occurring within,
structure of and output from the fore arc, volcanic arc, back arc, and
mantle wedge. Of particular interest are studies that (1) link processes
occurring in different parts of the subduction system, for example,
relationship between subduction input and output in the fore arc and
volcanic arc, material fluxes through the system, how differences in
subduction parameters (e.g., slab dip, crustal/lithospheric thickness)
or mantle wedge structure/composition affect magma composition, the
relationship between fluid release and seismic activity, (2)
characterize the temporal and spatial evolution of the subduction system
(e.g., changes in angle and dip of the subucting slab, fore-arc fluid
venting, and in the structure, chemistry, explosive activity, and
eruption rates of the volcanic arc), and (3) address the long- and
short-term hazards related to the subduction zone, such as the origin
and consequences of earthquakes, submarine and subaerial landslides/mass
wasting, tsunamis, and volcanic activity (eruptions and gas venting). By
the end of this decade, the Central American subduction system will be
one of the best studied on Earth. A major goal of this theme will be to
integrate the considerable international efforts that have been focused
on the Central American subduction system (e.g., U.S. Margins program,
German Collaborative Research Center SFB574, CRISP Drilling into the
seismogenic zone) with local projects carried out by geoscientists
throughout Central America. It is expected that this theme will remain
open for 3 years.

Two GSA 2008 Meeting Sessions (5/19/08)

1. Mixed Siliciclastic-Carbonate Systems: Mixing through Time and Space
2. Lithospheric Structure and Geologic Evolution of the Gulf of Mexico Passive
Margin

____________________________________________________________________

1. Announcement of session on Mixed Siliciclastic-Carbonate Systems: Mixing
through Time and Space; GSA Annual Meeting Houston, 5-9 October 2008

Dear Colleagues,

We are writing to request abstract submissions for a technical session at the
Joint GSA/GCAGS/HGS Annual Meeting to be held 5-9 October 2008 in Houston.

The session is titled Mixed Siliciclastic-Carbonate Systems: Mixing
through Time and Space. Carbonate and siliciclastic sediments/strata are
typically studied separately.However, there are numerous examples both in the
rock record and in modern environments where these sediment types interact on
various temporal and spatial scales. The interaction of carbonate and
siliciclastic sediments has been poorly studied and remains a gap in the
stratigraphic community's understanding of sedimentary systems. This session
will foster discussion of mixed systems by bringing together carbonate and
siliciclastic stratigraphers.

If you can share work on mixed systems, please consider submitting an abstract
for this session. Currently the session is listed as oral only, but a poster
session is also likely to be developed. The GSA abstract deadline is 3 June
2008.

Please forward this request to any colleagues that may be interested.

2. Lithospheric Structure and Geologic Evolution of the Gulf of Mexico Passive
Margin Geological Society of America 2008 Annual Meeting
5 - 9 October 2008
Houston, TX

Abstract deadline: June 3, 2008 Topical Session T64. Lithospheric Structure and Geologic Evolution
of the Gulf of Mexico Passive Margin (Organized by Libby Anthony, Steve Gao, and
Bob Stern)

Cosponsored by:
* GSA Geophysics Division
* GSA Structural Geology and Tectonics Division
* GSA South-central Division
* Gulf Coast Association of Geological Societies

Keynote speakers:
* Randy Keller - Geophysical evolution of the Gulf Coast.
* Tim Lawton - Tectonics of northeastern Mexico: salt diapers, mega-shear
accommodation and Cenozoic uplift
* Jim Pindell - The onshore-offshore evolution of the Gulf of Mexico.

Passive margins are hundreds of kilometers across and consist of
thick sedimentary sections built above broad transition zones that
separate oceanic and continental crusts and lithospheric mantles.
Link to EOS Forum article. Your interest in Texas and Gulf geology
would be a positive contribution to this session, and we urge you to
submit an abstract. Please also share this email with other
colleagues with similar interests. We hope to see you in Houston!

Session description:

Only by studying passive margins can we understand how oceanic and
continental crust and lithosphere merge into each other, and what
controls the massive subsidence that allows many thousands of meters
of sediments to accumulate, such as underlies the 2008 meeting site
in Houston. The sedimentary section of passive margins harbors
most of the undiscovered hydrocarbon reserves and is the focus of
intense study, exploration, and drilling by oil companies. Passive
margins straddle the divide between continental and marine geology,
posing special challenges for academic scientists that wish to carry
out comprehensive studies. The nature of the underlying
transitional crust and lithosphere is much more poorly studied.
This session will focus on a wide range of issues related to the
geology and geophysics of the Gulf of Mexico. Furthermore,
the transportable seismometer array of NSF initiative "EarthScope"
is planned to traverse the continental part of the region beginning
in 2010 and this technical session will help prepare the community
to take advantage of the new that this deployment promises to
provide.
