All,

Please consider attending the 2015 Interior of the Earth Gordon Research Conference (June 7-12) and Gordon Research Seminar (June 6-7), both at Mt. Holyoke College, MA USA. This year’s Gordon Research Conference has the theme “Surface Connections. As always, the GRC will include presentations on contemporary topics of interest from those actively engaged in new research and will facilitate extensive discussion after talks. A summary of sessions, session chairs, and speakers is below. A more detailed program is available online.

Further, please encourage post-docs and graduate students (and very junior research scientists/faculty) to consider attending the Interior of the Earth Gordon Research Seminar that immediately precedes the GRC.

The seminar, chaired by Heather Ford (Yale University), is meant for graduate students, post-docs, and very junior faculty or research scientists . It as the theme “The Structure, Properties and Evolution of Plate Boundaries’ and will include chiefly sessions contributed from attendees, with one keynote address from a senior researcher. The GRS will also include a career mentorship component on the subject of communication in the earth sciences. Normally those who attend the GRS also attend the GRC.

The registration deadline is May 9, 2015 for both the Conference and the Seminar. Those wishing to contribute talks to the Gordon Research Seminar need to submit abstracts before March 6, 2015.

Horton, J.W., Jr., Chapman, M.C., and Green, R.A., eds., 2015, The 2011 Mineral, Virginia, Earthquake, and Its Significance for Seismic Hazards in Eastern North America: Geological Society of America Special Paper 509, 431 p.

The magnitude ~5.8 Mineral, Virginia, earthquake of 2011 was the largest to occur in the Appalachian region in more than 100 years. It was felt over much of the eastern United States and southeastern Canada, caused significant damage from central Virginia to the National Capital Region, and was responsible for the automatic safe shutdown of a nuclear power station. It invigorated interest in earthquake processes, hazards, and preparedness along the Eastern Seaboard, and responses of the science and engineering communities to this rare event serve as models for responding to future events. The earthquake provided important new seismologic, engineering, geologic, hydrologic, and geophysical data that contribute to the understanding of earthquakes in eastern North America and to better assessment and mitigation of seismic hazards. This collection of 23 chapters makes these results available for geoscientists, engineers, and decision makers interested in understanding earthquakes and seismic hazards in eastern North America and other intraplate settings.

Please see below for session of interest to the GeoPRISMS community that will take place at the GSA Cordilleran Section annual meeting, 11-13 May, 2015, in Anchorage, Alaska.

Abstract Submission Deadline is February 10

Session title:

T10. Tempo of Arc Emplacement and Accretion

Organizers:

Elisabeth Nadin (U.of Alaska – Fairbanks), Chad Hults (National Park Service), and Erin Todd (USGS)

Session description:

Modern intra-oceanic arc systems (IOASs) have diagnostic features depending on their age. Re-assembling these features can be quite difficult in accreted IOASs, which have often undergone prolonged and complex tectonic histories. We welcome submissions that help clarify the nature and timing of arc assembly and accretion in modern and ancient settings.

Confirmed invited presenters:

Sue Kay (Cornell U.)

Are you an undergraduate interested in working on a seismological research project in the summer of 2015?
If so, consider applying for an IRIS Summer Undergraduate Internship (http://www.iris.edu/internship)

Once selected, your summer experience will begin with a one-week orientation held on the campus of an IRIS institution the last week of May 24 to May 30, 2015 (for those students whose quarter has not yet completed, alternative arrangements can be made). The goal of the orientation period is to develop a strong sense of community among interns, provide training in distance collaboration and introduce you to some of the most exciting aspects of modern seismology.

Following this week you will spend 8 to 10 weeks working on a seismological research project with researchers at an IRIS member intuition. Research projects may involve the deployment of seismic instruments in the field (within the US or internationally), and/or analyses of seismic data in a lab setting with the ultimate goal of producing results to be presented at a national scientific meeting. Each project will provide you with ample opportunities to:

* conduct research with state of the art geophysical data and leading researchers at IRIS institutions

* develop an understanding of scientific inquiry, including designing and conducting scientific investigations, defending scientific argu¬ments, and preparing publications

* gather, manage, and convey information, using various skills, strategies, resources, and

* learn, use, and evaluate technologies for the collection and study of geophysical data

Your summer research project will culminate with the opportunity to experience the exciting atmosphere of a professional meeting, while presenting your results. In the past, most interns and their hosts have chosen to present at the Fall American Geophysical Union (AGU) meeting held in San Francisco in early December.

As an IRIS Intern you will receive…

* A weekly stipend ($550/week for 9 – 11 weeks)

* Funding for travel to the orientation as well as room and board

* Funding for travel to the home institution of your research host

* Assistance securing housing at the host institution

* Funding for any additional expenses related to fieldwork

* Funding for travel to a professional meeting to present your results along with the associated meeting costs (travel, registration, abstract submission fee and per diem)

Minimum Requirements

* 3.0 GPA

* Two semesters of both Math & Physics

* Prior experience or coursework in seismology or geophysics is not a requirement

* Computer programming (Matlab, Mathmatica, C++, Java etc) a plus

The deadline to apply is February 1, 2015

Dear colleagues,

The American Mineralogist has now opened a Special Section in its Centennial Volume (2015-2016) on the theme of “New advances in subduction zone magma genesis”.

The Special Section is now open for submission (see details below), and will remain open until December 31, 2015. Editors for this special section are Susanne M. Straub and Heather Handley.

An important aspect is that American Mineralogist is set to become a more general journal for the Earth Science, as reflected in the subtitle of “A Journal of Earth and Planetary Materials”. This means that manuscripts are now accepted that could go to Geochim CosmochimActa, Contrib Mineral Petrol, G-cubed, Earth Planet Sci Lett, J Volcanol Geotherm Res, etc.

Here are some facts that to assist your decision to contribute to this volume:

– American Mineralogist offers print-on-demand which means that papers are published online as they are accepted, without waiting for the closure date for the Special Section. Once the section is closed, a journal-formatted collection of all the papers will be printed. The online publication date of the paper will be retained.

– Shorter papers are encouraged. While American Mineralogist accepts long papers as well, the regular articles have a 30 printed page limit (or a rough limit of 100 manuscript pages, when text, figures, tables etc. are taken together).

– American Mineralogist offers unlimited color in the on-line version of the journal is free to all MSA members ($80/year, and that includes Elements and American Mineralogist subscriptions).

– Color in the print version is $450/paper – not per page, but per an entire paper. However, if a paper has a huge amount of color maps, the fee may increase.

– American Mineralogist is cited in ISI and Scopus

How to submit a paper to the special section of American Mineralogist

1. Go to http://minsocam.allentrack.net —be sure cookies are on and Java enabled. Use the most recent version of Netscape, Explorer, Safari, etc. Register and then log in.

2. Full manuscript preparation guidelines are available at http://www.minsocam.org and include a handy list of abbreviations and other style information available on the web site.

Please feel free to send questions anytime to the volume editors (Straub/Handley), and also a short notice of intent and preliminary paper title anytime.

Best wishes,

Deep Carbon Observatory Thematic Institute: “Carbon from the Mantle to the Surface”

1-3 JULY 2015 (in conjunction with the 2015 CIDER Summer Program)

University of California, Berkeley

Berkeley, California USA

Deadline to Apply: February 28, 2015

Is the planet currently ingassing or outgassing carbon?

This defining question and others require an exploration into the forms and fluxes of carbon — from diamonds to volcanoes, from marine carbon to carbonated melts, and from the mantle to the surface and back again.

The Deep Carbon Observatory is sponsoring this 3-day Thematic Institute at UC Berkeley to bring together 50-75 researchers and young scientists with broad international representation in geochemistry, experimental petrology, volcanology, geodynamics, thermodynamics, geophysics, paleoclimate and geology.

The DCO TI will be run in parallel with the CIDER Summer School on “Mantle Interactions with the Hydrosphere and Carbosphere.” Interested and qualified students and postdocs are encouraged to apply to both.

Investigating Cascadia Subduction Zone Geodynamics Through Scientific Ocean Drilling

University of Washington, Seattle

April 29 – May 1, 2015

http://usssp-iodp.org/workshop/cascadia/

Deadline for US participants to request travel support: January 31, 2015

Deadline for others to register: March 15, 2015

Recent devastating megathrust earthquakes in Sumatra, Chile and Japan have heightened awareness of the hazard posed by subduction zones and the inevitability of a comparable earthquake along the coast of the Pacific Northwest. At the same time, there have been extensive efforts to expand the infrastructure and funding for scientific studies of the Cascadia subduction zone. The NSF GeoPRISMS program identified Cascadia as a Primary Site, cabled observatories have been installed off both the US and Canada, NSF’s Amphibious Array Facility is supporting a 4-year community experiment to understand the seismicity and seismic structure of the Cascadia margin and Juan de Fuca Plates and significant active-source seismic imaging, magneto-telluric and heat flow experiments have been undertaken offshore. However, only very recently have efforts been initiated to extend geodetic observations above the subduction zone offshore, even though such observations are critical for understanding the dynamics and hazards potential of the Cascadia megathrust. Offshore geodetic studies must be conducted on a decadal timescale to fully resolve many interseismic deformation processes and downhole geodetic and hydrogeological observations are some of the most sensitive tools for understanding subduction zone dynamics. The objective of this 2½-day workshop is to develop the framework for a full IODP proposal to be submitted in 2016 by considering how drilling can best contribute to our scientific understanding of the deformation of the Cascadia subduction zone, the degree of interseismic locking across and along strike, and its seismic and tsunamigenic potential.

In order to accomplish this objective the workshop will:

* Review the state of knowledge of the Cascadia Subduction Zone, existing infrastructure, and experimental initiatives that are underway.

* Review the results of drilling and downhole geodynamic observations in other subduction zone settings.

* Identify and prioritize the scientific questions in Cascadia that are best addressed by ocean drilling and downhole instrumentation.

* Prioritize borehole instrumentation that is required to achieve the scientific objectives.

* Develop a plan for a borehole observatory array (or series of transects) that can be designed in light of realistic drilling/infrastructure constraints, structural context, and define a strategy for the complementary integration of borehole, seafloor, and land-based monitoring.

By the end of the meeting, a group of proponents will be identified to lead the writing of a proposal.

The workshop will be open to U.S. and international participants. Travel funds for US participants will be available through the US Science Support Program for IODP. Travel funds will be allocated based on the submission of a short statement of interest and on need – a portion of the travel funds are specifically reserved for graduate students and early career scientists.

The meeting web page (http://usssp-iodp.org/workshop/cascadia/) includes a link for registration and requests for travel support for US participants.

Non-U.S. participants should inquire with their own IODP national offices for possible travel support, e.g., http://www.essac.ecord.org/index.php?mod=about&page=partners for European and Canadian applicants, and <info@j-desc.org> for Japanese applicants.
