  The NASA Cosmochemistry Program and the Lunar and Planetary Institute are sponsoring a five-year scientific initiative entitled "Oxygen in the Solar System: Origins of Isotopic and Redox Complexity." The goal of the initiative is to better understand the important cosmochemical roles of oxygen and oxygen compounds in all their manifestations. The initiative consists of four teams: Terrestrial Planets, Asteroids and Meteorites, Outer Planets, and Earliest Solar System Materials. Additional information can be accessed on the LPI Web site at

  The Earliest Solar System Materials Team and the Outer Planets Team have organized a combined workshop, to be held September 19–22, 2005, in Gatlinburg, Tennessee ( Oral and poster sessions will be held in meeting facilities at the Glenstone Lodge, which will also provide the primary accommodations for meeting attendees. Note that this meeting immediately follows the 2005 Annual Meeting of the Meteoritical Society and is being held at the same venue.

  The scope of the workshop is primarily focused on the cosmochemistry of oxygen, including but not restricted to topics such as nucleosynthesis of oxygen, oxygen in the interstellar medium, distribution and isotopic composition of oxygen in presolar grains, oxygen in the Sun (now and in the past), the role of oxygen in controlling condensation and evaporation processes in the nebula, oxygen in the gas giants and their icy moons, distribution and isotopic composition of oxygen in IDPs and implications for comets, the delivery of volatiles to the terrestrial planets, oxidation state of the solar nebula, oxygen isotopes in meteoritic materials and implications for oxygen isotopic reservoirs in the solar nebula, and the origin of 16O variations in early solar system materials. The three-and-one-half day workshop will consist of seven sessions comprising approximately 45 to 55 oral presentations, plus one poster session. Morning sessions will nominally be scheduled from 8:30 a.m. until noon, and afternoon sessions will be scheduled from 1:30 to 5:00 p.m. However, in the interest of promoting discussion, these times will remain flexible. The program will consist of both invited and contributed talks and posters. Each major subtopic will have one to three 20-minute presentations to provide an introduction and background. These will be followed by four to six 10-minute talks per session, with the remaining time allotted for discussion. The number of oral presentations will be limited to encourage and facilitate discussion.

Audio-visual equipment available for oral presentations will include one LCD projector and two overhead projectors. (NOTE: A 35-mm carousel slide projector will NOT be available. All electronic presentations must follow workshop guidelines as detailed in the Instructions for Electronic Presentations.)

A poster session is scheduled for Tuesday evening, September 20, 2005. Posters will remain on display throughout the entire meeting.

  All abstracts, whether invited or contributed, must be submitted electronically to the Lunar and Planetary Institute via the electronic abstract submission form by July 7, 2005, 5:00 p.m., U.S. Central Daylight Time (CDT). Abstracts will be limited to one (1) page, including graphics, tables, and references. Templates and detailed instructions for formatting and submitting your abstract are provided.

Note that electronic submission of files is not always instantaneous; gateways can be shut down temporarily, local routers can fail, network traffic can be heavy, etc. Because your file must be received at the LPI by 5:00 p.m. CDT, it is in your best interest to submit early to allow for possible technical problems or delays in transmission. Please DO NOT wait until the last minute to access the system; access to the Web form will terminate at 5:00 p.m. CDT.

Selected students may have the workshop registration fee waived in return for their assistance with the audio-visual services at the meeting. Please indicate your interest to volunteer for this service on the abstract submission form.

  A block of 75 guest rooms has been reserved at the Glenstone Lodge, 504 Historic Natural Trail, Gatlinburg, Tennessee, at a special, very favorable rate of $76.00 plus 12.5% tax (single or double occupancy). Participants should register directly with the Lodge at 800-362-9522 or The first night's room/tax deposit is due at the time of reservation, with the balance due at check-in.

Gatlinburg is the popular gateway to the Great Smoky Mountains National Park, known for its spectacular flora, 900 miles of hiking trails, and stunning mountain vistas. Climate varies tremendously within the park by season and elevation. Conditions often change without notice. Be prepared for almost anything at anytime ( Gatlinburg also offers a peaceful, safe environment with many restaurants and shops within easy walking distance or accessible by trolley cars.

  Gatlinburg is serviced by Knoxville's McGhee-Tyson Airport (TYS), which has direct flights from Atlanta, Charlotte, Chicago, Cincinnati, Dallas/Ft. Worth, Houston, Orlando, Pittsburgh, St. Louis, and Washington. The airport is ~50 miles (~80 km) from Gatlinburg. Van service can be reserved in advance to shuttle meeting participants to and from the airport at nominal cost, and rental cars (desirable if you wish to take advantage of the National Park) are available in the terminal.

  A fee of $250.00 ($200.00 for students) will be assessed each participant to cover conference services. You must preregister and prepay by August 17, 2005, to avoid a $50.00 late fee.

A welcome registration reception will be held on Sunday evening, September 18, from 5:30 to 7:00 p.m. This event, as well as the poster reception on Tuesday evening and meeting breaks refreshments, is included in the registration fee.

Please return the downloadable registration form with your payment before August 17, 2005, to avoid a $50.00 late fee, or you may use the electronic registration form if paying by credit card. Foreign participants who state on the registration form that they have a currency exchange problem may pay in cash at the meeting (and avoid a $50.00 late fee) if they return the form by August 17, 2005.

Cancellations with requests for refunds will be accepted through Friday, September 2, 2005. Please note that a $25.00 fee will be charged on all cancellations.

  Further details about the program will be included in the final announcement, available on this Web site around August 10, 2005.
