Subject: "Fluid seeps and shallow migration phenomena at continental
margins" and the Earth System Processes meeting in Edinburgh in June 2001:
Dear Colleagues,
Below you will find a description of an Earth System Processes theme
session called "Fluid seeps and shallow migration phenomena at continental
margins: impacts spanning the lithosphere, biosphere and hydrosphere".
Kathy Campbell (University of Auckland), Casey Moore, (UC, Santa Cruz) and
I will be coordinating this session. We are sending you this information to
encourage you and your students / colleagues to consider participating in
this exciting meeting by submitting an abstract on your recent work
(details below). In order to facilitate discussion and ideas for future
research the organizers have set up the meeting so that the bulk of the
scientific presentations will be in poster format. There will be three to
six oral presentations other than the two keynote addresses for our
session. The oral presentations will be scheduled to maximize viewing and
discussion at the poster sessions. We hope to see you in Scotland!

T15. Fluid seeps and shallow migration phenomena at continental margins:
impacts spanning the lithosphere, biosphere and hydrosphere
Kathy Campbell (Auckland, e-mail: [log in to unmask]), Lidia
Lonergan (Imperial College, London; [log in to unmask]) and Casey Moore
(UC, Santa Cruz; [log in to unmask])
This session examines seafloor seepage features and shallow manifestations
of water and hydrocarbon flow in modern and ancient environments. The
fate of fluids and their effects of fluids on the lithosphere, biosphere
and hydrosphere will be emphasized.
This theme session will focus on both seafloor seepage features and shallow
manifestations of water and hydrocarbon flow. Surface observations at
modern continental margins will be linked to shallow subsurface migration
features both in exhumed outcrops and in seismic reflection images. The
session will also consider Earth System Linkages in this interdisciplinary
arena by examining the fate and effects of fluids in/on the lithosphere,
biosphere, and hydrosphere.
Fluid seeps along continental margins directly reflect hydrocarbon
migration and sources, impact and sustain biological systems, alter the
overlying water and air quality, and influence coastal groundwater. The
magnitude of these impacts is unknown and the fundamentals of the seepage
system poorly understood. The proposed theme session intends to attract
papers outlining seep and migration phenomena from the North Sea and
adjacent margins, while drawing comparisons worldwide to both modern
phenomena and well preserved ancient examples.
Session Keynote speakers:
Ian MacDonald: Geochemical Environmental Research Group, Texas A&M
University, "The Northern Gulf of Mexico Slope - a Seep Laboratory"
Alan Judd, University of Sunderland: "Fluid seeps and their role in the
global carbon cycle"
