MEETING LOCATION AND DATE
||The Bridging the Gap II workshop will be held September 2226, 2007, at the John H. Chapman
Space Centre, headquarters of the Canadian Space Agency (CSA), which is located in Saint-Hubert on the outskirts of
Montréal. The Centre, about a 45-minute drive from Montréal-Pierre
Elliott Trudeau International Airport, is conveniently located near downtown Montréal at 6767
Route de l'Aéroport, Saint-Hubert, Quebec, J3Y 8Y9.
Date: September 2226, 2007
Location: Saint-Hubert, Quebec
PURPOSE AND SCOPE
||Impact cratering is a fundamental geological process that affects all solar system objects with a
solid surface. The formation of meteorite impact craters involves complicated physical processes
that occur over a wide range of temperatures, pressures, and spatial scales, and consequently a
multidisciplinary approach to research is required to improve knowledge of the cratering process.
The purpose of this workshop is to bring together researchers from various disciplines to address
one of its major outstanding problems: the effect of target properties, such as porosity, volatiles,
and layering, on the impact cratering process. The workshop builds upon the successful
workshop Impact Cratering: Bridging the Gap Between Modeling and Observations,
which was held in Houston, Texas, in February 2003.
||The five-day meeting will consist of an optional two-day field trip to the ~55-km-diameter
Charlevoix impact structure on September 2223, followed by a three-day workshop on
September 2426, at the John H. Chapman Space Centre, headquarters of the Canadian Space
Agency (CSA), Saint-Hubert.
The workshop has been organized into five topical sessions and a final integrated discussion on
the last afternoon of the meeting. Each session includes invited oral
presentations and contributed oral and poster presentations. Following the successful format of
the first Bridging the Gap workshop, each session includes invited speakers from the
theoretical/modeling community and the field/planetary observations community.
A general ground rule for every contribution is that "observationalists" are required to discuss
how their data constrain models of the impact process, and "modelers" are required to discuss
observations that could constrain their models.
The workshop will begin with a two-day field trip to the ~55-km-diameter Charlevoix impact
structure, which is about a four-hour drive from Montréal. Field trip participants will depart
from the workshop hotel,
Holiday Inn Montréal Midtown,
at 7:30 a.m. on the morning of September 22. Participants will return to the hotel in the evening of
September 23. Unfortunately, other pick-up locations are not possible due to Quebec transit regulations.
A prompt departure early on Saturday will be essential, so participants must arrive in Montréal on
Friday evening. Please arrive at the hotel lobby no later than 7:15 a.m. to ensure a prompt departure. Travel to and from Charlevoix and accommodations for the field trip are
included in the field trip registration fee.
Only 54 places are available and registration will be on a first-come, first-served basis.
Participants are strongly advised to register early for the field trip.
The Charlevoix impact crater is located on the north shore of the St. Lawrence River about 100 km
northeast of Quebec City and about 400 km from Montréal. The region is an eroded plateau
with relief of about 1 km and is renowned for its striking terrain and scenic and cultural diversity.
The crater is mid-Paleozoic in age, about 55 km in diameter, and formed in crystalline rocks of
the Canadian Shield with relicts of lower Paleozoic sedimentary rocks that comprised a relatively
thin cover at the time of impact. It is an excellent example of a peak-ring structure with a
pronounced central peak, a subdued ring, and a peripheral trough. Virtually all impact melt rocks
and breccias have been removed by erosion, so it provides an exceptional opportunity to examine
shock effects and structures in the immediate subjacent rocks. Later tectonic events linked to the
formation of the Appalachian Mountains and the St. Lawrence graben have bisected the crater,
and the region is still subject to significant earthquakes.
It is anticipated that the distances to be covered and the challenging topography will allow ~12
stops to be made. These will provide views of the terrain and opportunities to examine and, in a
few cases, sample exposed rocks within the crater. The field trip will be led by Mike Dence and John Spray.
The temperatures at Charlevoix vary from about 15°25°C midday to 510°C in the evening.
The weather can vary from bright sun to mists or rain and strong winds if a tropical storm passes up
the Atlantic seaboard. Stout footwear is desirable. Walking distances may be as far as 23 km over flat
terrain but will be limited by time constraints at the stops.
Accommodations on Saturday night will be at the Fairmont Le Manoir Richelieu overlooking the
St. Lawrence River at La Malbaie/Pointe-au-Pic, where an evening buffet and discussion
meeting will be held. Box lunches on both days and a cold breakfast on Sunday will be
provided. The field trip fee does not include expenses in Montreal incurred before the field trip or the
cost of the evening meal on Sunday which will be a dinner buffet in Quebec City at an estimated cost of $20.00-25.00.
The bus will reach the workshop hotel in Montreal by 9:00 p.m.
Workshop sessions will begin the morning of September 24, and continue through the
afternoon of September 26. Each session will generally begin with two or three invited 20- or 30-minute talks,
by modelers and observationalists, with the remainder of the talks as
contributions. Five half-day oral sessions are planned, with tentative session titles focusing on
the effect of target properties on the following key aspects of the impact cratering process:
- Initial energy deposition and shock wave propagation
- Shock melting, metamorphism, and damage to the target
- Mechanics of complex crater formation
- Plume evolution and ejecta emplacement (proximal and distal)
- Environmental consequences of impact cratering
Contributed oral presentations are limited to 15 minutes, including questions, discussion, and speaker transition.
Audio-visual equipment available for oral presentations includes one LCD projector and one PC laptop and/or desktop computer.
Please bring your electronic presentation on a CD-ROM or USB memory drive to download onto the laptop PC provided in the
meeting room (preferred option) or bring your electronic presentation on your own laptop. The meeting room will be
open prior to the beginning of the morning presentations and during lunch for downloading afternoon presentations.
The workshop will open with an overview presentation summarizing the results from Bridging
the Gap I and providing updates on some of the major questions and tasks that emerged from that
workshop (e.g., the ongoing impact codes validation effort; databases of terrestrial impact
craters; recent and future drilling of impact structures; impact-related missions). The workshop will close with an
integrated discussion focusing on the achievements since Bridging the Gap I and highlighting outstanding problems in impact
All sessions will include ample time for questions and discussion. The final afternoon session of
the workshop will be dedicated to discussion.
Contributed posters will be displayed for the duration of the workshop in the Salle III room next to the
conference hall. A dedicated poster session and reception is planned from 6:00 to 8:00 p.m. on Tuesday evening, September 25.
Participants will also be encouraged to view posters during coffee breaks and at lunch.
Each poster will have a space 36" × 36" for display. Posters will be displayed on free-standing
panels. Two presenters will share one side of one panel, so it is important that displays are
confined to the specified limit. Posters must be designed to be attached to the panel with push
