Nov. 1, CISM (International Center for Mechanical Sciences),
Piazza
Garibaldi 18, Udine, Italy
8:30 ISSEP Chair John Tarduno and ESSEP Chair Neil Lundberg opened the
sixth Joint Meeting of the Scientific Steering and Evaluation
Panel for the dynamics of Earth's Interior and Earth's Environment.
After
introduction of panel members the meeting host, Michele Rebesco, offered
some information on local logistics of the meeting. The panel thanked
Michele for organizing the pre-excursion field trip to Venice, and
for
his overall help in organizing the meeting.
JOIDES Office Report
Next the panel heard from Jeff Schuffert, who gave the JOIDES office
report. Jeff reported on the two new Program Planning Groups
(Hydrogeology and Arctic). The Hydrogeology group is well on its way
to
be established (offers have been made). The
chair for the Arctic PPG has yet to be identified (offers have been
turned down because of perceived conflict of interest).
Jeff next reviewed some proposal statistics. Thirty seven new or revised
proposals were received; with one exception they were received by the
deadline. The average proposal length is close to the published guidelines.
Craig Manning noted the panel's appreciation of the efforts by the JOIDES
office to enforce the proposal deadlines and guidelines.
Warner Brueckmann noted that 6 proposals were submitted electronically.
This may increase in the future; the SSEPs may consider receiving these
as electronic (pdf) files in the future.
SCICOM Report
Alastair Robertson reviewed actions taken at the last (August) SCICOM
meeting. He mentioned that the Woodlark proposal (560) was discussed.
SCICOM decided not to consider it in the ranking. 19 of 25 proposals
considered for ranking (6 were excluded because they were out of the
area
of expected operation). Alastair next reviewed the results of the SCICOM
ranking (reproduced below):
523 Hotspot
465 SE Pac
486 Eocene
525 Peridotite
500 H2O
499 ION Eq. Pac.
546 Hydrate Ridge
505 MCM
534 Shatsky Rise
510 Marion Plateau
----------------------------------
489 Ross
553 Cascadia
451 Tonga
535 Slow spreading
477 Okhotsk
549 OMZ
478A E. Nankai A
478B E. Nankai B
355 Peru
After the ranking OPCOM proposed several scheduling options (for
proposals above the line in the list above). These include scheduling
into FY02. SCICOM voiced its desire to complete ION; also, they
are
committed for development/implementation of ACORK. The final schedule
has
yet to be decided.
In other news, Alastair mentioned that SCICOM would be willing to
consider setting up a new biosphere PPG with a different membership
and
focus.
NSF Report: Jamie Allan
Jamie briefly reviewed the funding structure for the new panel members.
He noted that Margaret Leinen has joined NSF (she is a prior EXCOM
member). He gave a summary of the
CDC (conceptual design committee), which will provide input for the
design of a new non-riser ship; the US has agreed to capitalize this
ship.
JOI Report: Kate Moran
Kate Moran provided a broad review of the current ODP structure and
of
planning for post 2003. She also discussed ongoing technology development
include HYACE,
and laboratory updates of the ship for deep biosphere and gas hydrates
work. Kate also discussed recent meetings with industry; ideas for
cooperation were well received. Craig Manning asked if this was mainly
seen as a means to generate
more capital for ocean drilling. Kate replied that industry had
scientific objectives that could contribute to the overall effort.
She described the relationship of IPSC to other parts of the JOIDES
advisory structure. IPSC has established several working groups including
one to write a science plan for
a new program, taking input from the COMPLEX and CONCORD meetings.
Working groups for technology and industrial liaisons have also been
established.
The Japanese DIET has approved over $500M for design and construction
of
a new riser vessel. H. Tokuyama noted that he had some updated diagrams
of the new ship (these were reproduced and distributed later in a joint
session).
Kate continued by explaining US activities for post 2003 drilling. She
discussed the formation of the conceptual design committee by USSAC.
It
is hoped that the new ship will have capabilities that extend into
shallow water. The work of the committee
will be used as input for an RFP. The ultimate decision on the new
non-riser ship will decide whether a "hiatus" in drilling occurs.
Kate discussed several outreach efforts by JOI including the ocean
drilling seminar series on Capital Hill.
10:15-17:00 Separate ISSEP and ESSEP Meetings to Review Proposals
The SSEP chairs reviewed the conflict of interest rules prior to the
start of proposal reviews. Proponents are excluded, as are those having
active projects closely related to the projects
proposed. SSEP members at the same institutions as a proponent must
identify themselves to the SSEP chairs prior to review discussions.
During the meetings (Nov 1-3), the SSEPs considered the following

Julie Morris (incoming ISSEP chair)
Kate Moran (JOI)
John Farrell (JOI)
Warner Brueckmann (JOIDES office)
Jeff Schuffert (JOIDES office)
Alastair Robertson (SCICOM liaison to ISSEP)
The group met to discuss several issues including reporting by the
current and future PPGs. John Tarduno stressed that suggested revisions
to the original SCICOM motions concerning PPG-chair attendance at the
SSEP meetings were intended to apply to the new PPGs rather than all
the
current PPG (because most of the current groups have completed, or
soon will
complete their work). The SSEP chairs asked Warner Brueckmann
and Jeff
Schuffert to communicate this to Bill Hay. Julie Morris agreed to draft
suggested revisions to the SCICOM motion discussing PPG meetings and
reporting that are consistent with the JOIDES organization structure
(i.e. PPG report to the SSEPs).
20:15 Special Meeting to Discuss Marion Plateau-Shatsky Rise Scientific
Issues, Sala Rosone, Astoria Hotel
Attending:
John Tarduno (ISSEP chair)
Neil Lundberg (ESSEP chair)
Julie Morris (incoming ISSEP chair)

Randy Forsythe (ISSEP)
Kate Moran (JOI)
John Farrell (JOI)
Warner Brueckmann (JOIDES office)
Jeff Schuffert (JOIDES office)
On 29 Oct. the SCICOM chair Bill Hay requested that the SSEPs evaluate
a
drilling plan involving Proposals 510 (Marion Plateau) and 534 (Shatsky
Rise) proposed by the ODP managers. Specifically, SCICOM sought the
SSEP's opinion as to whether the highest priority scientific objectives
could be met by the plan. Bill Hay requested that the SSEP comments
be
sent by 4 Nov to the JOIDES office.
In response to this request, the SSEP chairs asked several members to
meet with representatives from the JOIDES office, JOI and SCICOM to
discuss the plan.
Kate Moran presented the plan and its intent to maximize the overall
science achieved. If both programs could be shortened, both might be
incorporated into the FY01 drilling schedule.
The SSEP chairs asked Jamie Austin to provide his opinion on the impact
on the science presented in the Marion Plateau proposal.
The SSEP chairs asked Ellen Thomas to provide her opinion on the impact
of the plan on the science presented in the Shatsky Rise proposal.
Both reviews were followed by considerable discussion, which included
other SSEP members asked to attend the meeting. After this discussion,
a
consensus was reached. The chairs asked Steven Clemens to draft a
consensus statement for consideration during the joint ISSEP-ESSEP
meeting. Furthermore, the SSEP chairs asked Jamie Austin
and Ellen Thomas to prepare statements reflecting their opinions on
the
science that could be obtained in the plan with respect to Marion Plateau
(Jamie Austin) and Shatsky Rise (Ellen Thomas). The SSEP chairs thanked
everyone for their patience, with the meeting concluding at approximately
23:00.
Nov 2. 8:30-18:00 Separate meetings of ISSEP and ESSEP to continue
reviewing proposals.
In addition to separate meetings for proposal review, two additional
Review
Working Groups met to coordinate ISSEP/ESSEP comments:

Nov. 3.
8:30 Separate Panel Meetings
ESSEP Meeting
ESSEP required the balance of this session to complete discussions on
the remaining proposals. In addition, there was discussion on
SCICOM
rankings of proposals at the August 1999 SCICOM meeting. In particular,
discussion was sparked by questions that arose during review of
proposals 477 (Okhotsk and Bering Seas) and 549 (Arabian Sea OMZ and
Monsoons). A number of ESSEP members considered these to be
high-priority proposals, and watchdogs felt they had insufficient
information about why these were ranked low by SCICOM to be able
to convey useful suggestions to proponents.
ISSEP Meeting
John Tarduno reviewed the status of priorities discussed previously
by
the panel, in light of recently scheduled programs. The following is
a
brief summary of this review.
Mantle Dynamics: The recent selection of ION and LIP proposals, together
with previously scheduled legs addressing mantle flow (i.e. AAD) forms
a
coherent effort to address
geodynamics, ranging from the present day to the Cretaceous. LIP legs
have been exploratory. The next phase of drilling should build on these
efforts, and be geared toward specific hypothesis testing.
Oceanic Lithosphere: The AOL PPG, and reports from prior planning
meetings, have outlined several areas of progress desired in the general
area of oceanic lithosphere.
These include plutonic foundations, complete penetration of insitu
crust,
hydrothermal systems and core complexes. ISSEP has seen proposals in
all
of these areas and legs
will address specific items (e.g. Manus Basin hydrothermal systems).
However, a plan to link specific proposals has not been produced by
prior
planning groups and ISSEP
might consider attempting to draft such a plan (or plans). Also, the
panel should be aware that it's desire to see an Oceanic Core
Complex
drilled prior to the end of the present
program is a priority that did not appear in SCICOM's subsequent
discussion of program priorities (that was communicated to EXCOM.)
Mass Balances and Temporal variations at subduction zones: The panel
had
previously expressed the desire to see an effort drilled before the
end
of the present program to complement previously scheduled legs (i.e.
Leg
185) ; there appears to be sufficient proposal pressure in this area.
Convergent Boundaries: There has been considerable advance in this area
with 2 scheduled legs at Nankai. The original intent of these
proposals
was to study processes of deformation and fluid flow in the accretionary
wedge. The panel will need to consider how this relates to the
seismogenic zone drilling given priority at CONCORD (use of the new
riser
drill ship).
Extensional Boundaries: The chair noted that the lack of proposals in
this area is not surprising; the panel previously requested that a
program planning group be established to represent this area because
of a
perceived lack of proposals.
Earthquake processes: ODP has made considerable advances in this area
with the recent instrumentation of the Japanese trench (ODP Leg 186).
The
chair noted that we hadn't been receiving many other proposals of this
type and that the panel might consider soliciting additional proposals.
Jamie Allan noted that the principal reason for the lack of proposals
was
probably the lack of cables that could service new installations. Jamie
noted that new installations in the northeast Pacific might lead to
new
proposals.
10:45 Joint ISSEP/ESSEP Meeting
ODP-TAMU Report
Paul Wallace and Mitch Malone of ODP-TAMU provided a brief summary
(results of recent legs have been linked to the SSEP web site,
www.earth.rochester.edu). Paul reviewed developments during the recent
drydock. The ICPE (Inductively Coupled Plasma Emission Spectrometer)
will
be installed prior to Leg 187. Debbie Kelley asked about pressurized
water samples for biosphere studies. The ODP-TAMU liaisons will provide
more information on this issue to the SSEPs.
Logging Report
Tim Brewer briefly asked for feedback regarding the development
of new
logging tools (descriptions have been posted on the SSEP web site,
www.earth.rochester.edu/issep).
The SSEP chairs agreed to provide feedback on these new tools.
PPG Reports:
SWS PPG Presentation by Terry Quinn
Terry Quinn, co-chair of the SWS PPG, reviewed the progress and
goals of
the PPG. Terry provided the group with a report addressing scientific
issues (white papers) which have been
posted on the SSEP web site (www.earth.rochester.edu). Terry reviewed
the
challenges that the SWS-PPG has faced. Shallow water science
requires
alternate platforms or a
reconfiguration of the JOIDES Resolution. Terry reviewed the timeline
of
the PPG work and a science/technology matrix. Terry's presentation
was
followed by questions and comments. Jamie Austin noted that the project
planning should be incorporated into IODP. Paul Baker was surprised
that
only 2 main scientific issues were identified in the report/ white
papers; he felt there were many more important issues. Peter deMenocal
felt the community was mature scientifically but was technology limited.
The SSEP chairs thanked Terry for the update and noted that the panels
were beginning to see increased proposal pressure in the area of shallow
water systems.
Gas Hydrates PPG Jon Martin
Jon Martin provided a comprehensive review of the Gas Hydrates meeting
held in September, 1999 in Berlin. The meeting addressed two major
themes: (1) technical aspects of gas hydrates (status of existing tools,
development of new tools, needs for new tools involving sampling and
geophysical tools) and (2) prioritizing the most important issues
(developing a drilling strategy and identifying type areas to target).
Jon reviewed existing tools or those under development including
HYACE ,
the Pressure Core Sampler (PCS), The Davis/Villenger Temperature Probe
(DVTP), the Water Sampler Temperature Probe (WSTP), and
the Fissler
Water Sampler (FWS). Jon also discussed some new tools including the
TCP
device under development by Charlie Paull to measure pressure and
temperature and electrical resist. on the piston head of the APC device.
This might allow measurements on every APC run. Jon also discussed
a
catwalk IR temperature sensor gun.
This might develop into a routine measurement on cores.
Jon noted that the PPG was pleased with the selection of Hydrate Ridge
for scheduling. Hydrate Ridge will address tectonic BSRs through
drilling in an active margin setting. The group discussed what might
be
missing from the Hydrate Ridge effort that is still important for an
overall approach to understand hydrates. Items discussed included slope
stability, hydrate-climate links, importance of hydrates in a passive
margin setting, gas chemistry and thermogenic vs. biogenic gas,
destabilization of gas hydrate and non- BSR hydrates. For non-BSR
hydrates, the group considered several options, with input from Jon
and
John Tarduno who also attended the meeting. These included APL's that
might propose specific studies that could be done on
legs addressing other topics but drilling in locations where non-BSR
hydrate might be expected. In addition, routine techniques to identify
gas hydrates were discussed (such as collection of
catwalk temperatures).
Some PPG members were reluctant to suggest specific strategies that
would
follow the Hydrate Ridge Drilling but did express that the link between
slop stability/geohazards and climate was perhaps the most important
remaining issue.
The SSEPs have received a final report from the PPG which discussed
this
and other issues; the report has been made available to SSEP members
through the SSEP web page (www.earth.rochester.edu/issep).
12:00 Lunch Break
13:00 Continuation of Joint ISSEP-ESSEP Meeting
The panels thanked Piera Spadea for her work in the planning of the
meeting.
Marion Plateau-Shatsky Rise Plan
Next the panels addressed the Marion Plateau-Shatsky Rise plan proposed
by the ODP Managers. A discussion of this plan was requested by Bill
Hay.
The SSEP chairs asked Jamie Austin to start by reviewing what high
priority science would be accomplished from the original Marion Plateau
proposal in the ODP Managers plan. The SSEP
chairs asked Ellen Thomas to follow Jamie's presentation with a similar
review with respect to the Shatsky Rise proposal. Next, the SSEP chairs
asked Steve Clemens to present a draft SSEP
consensus statement on this issue. This statement represents the outcome
of a meeting held in the evening on 1 Nov (see above). The SSEP chairs
then asked the opinion of other SSEP
members who were asked to attend the 1 Nov. meeting (Ulrich Bleil
and
Randy Forsythe). After adopting some minor changes in wording the
consensus statement was adopted by the SSEPs
The SSEP chairs thanked Jamie Austin, Ellen Thomas and Steve Clemens
for
their presentations.
Attachments B-E are the written reports of the SSEP deliberations on
the Marion Plateau-Shatsky Rise discussions, sent on Nov. 4, 1999 to
the JOIDES Office.
Attachment B is a cover letter from the SSEP chairs
on the Marion
Plateau Shatsky Rise deliberations; Attachment
C is the Marion Plateau
Shatsky Rise Consenus Statement from the SSEPs; Attachement
D is
a Marion Plateau review statement, written by ESSEP watchdog
Jamie Austin; and Attachment E is a Shatsky Rise
review statement,
written by ESSEP watchdog Ellen Thomas.
Presentation of SSEP Motion by Julie Morris
A series of recommendations to SCICOM were presented by Julie Morris.
These recommendations were in part stimulated by events following
the
last SCICOM meeting including handling of the Marion Plateau and Shatsky
Rise proposals. After discussion
and minor revision the issue was called to a vote by Hans Brumsack;
seconded and approved unanimously. The motions are found in Attachment
F.
Discussion of Joint Proposals: Review Working Group Leaders

Explanation for the Leg 194 Plan comments from the SSEPs
At the request of SCICOM, the SSEPs considered the Leg 194 plan.
Comments were
limited to the likelihood of achieving high-priority science objectives
of the
original science plans outlined in Proposals 510 and 534.
Comments regarding
the process will be forwarded to SCICOM separately as part of the
SSEP minutes.
Three files have been submitted to the JOIDES office directly from
our meeting
in Udine to meet the requested Nov. 4 deadline. These include:
1. A short summary of the consensus of the two SSEPs
2. Specific comments from Marion Plateau watchdog Jamie Austin.
These
comments were solicited by the SSEP chairs and reflect a watchdog
rather than a
consensus view.
3. Specific comments from Shatsky Rise watchdog Ellen Thomas.
These comments
were solicited by the SSEP chairs and reflect a watchdog rather
than a
consensus view.
Respectfully submitted,

Attachment C: Marion Plateau - Shatsky Rise Consenus Statement
SSEPS Consensus
Shatsky Rise
The Leg 194 drilling plan meets a significant number of the highly
ranked
Paleogene objectives which are consistent with climate change components
of the
ODP Long Range Plan. Highly ranked objectives of Shatsky
Rise Proposal 534
which could be addressed by the Leg 194 plan include those related
to (1) the
Eocene-Oligocene green-house to ice-house transition, (2) the nature
and onset
of middle Eocene cooling, (3) ocean temperature, chemistry,
and biotic
response to the early Eocene warm episode, (4) carbonate dissolution
and
hydrate instability during the late Paleocene thermal maximum,
(5) biotic
effects and oceanic productivity collapse at the K/T boundary,
and (5) middle
Maastrichtian extinctions, circulation, and sea level change. High-priority
science objectives of Proposal 534 which are totally eliminated
from the Leg
194 plan are those related to the onset of the mid-Cretaceous greenhouse
climate and Cretaceous evolution of marine plankton and benthos.
Marion Plateau
The Leg 194 drilling plan seriously jeopardizes the high-priority
sea-level
timing and amplitude objectives and eliminates the rate-of-change
and
facies-response objectives, all of which are consistent with the
goals of the
ODP Long Range Plan. Recovery of sufficient material from
specific horizons at
multiple locations throughout the Proposal 510 transect is critical
to
evaluating sea-level timing and amplitude, as well as sea-level
rate of change
and facies response. Given the difficulty anticipated in
recovering
coarse-grained carbonate clastics (especially at the more proximal
locations)
as well as interbedded pelagic units, there is significant concern
that
elimination of one or more holes at multiple sites as well as the
elimination
of sites CS-03, 08, and 09 significantly reduces the likelihood
of recovering
these critical intervals.
Attachment D: Marion Plateau review statement (Jamie Austin)
(from Jamie Austin, ESSEP watchdog for Proposal 510, 11/3/99)
Marion Plateau
A meeting of the SSEPs chairs and Marion / Shatsky watchdogs, together
with
representation from JOI and SCICOM, met on 1 November to consider
proposed
changes to the two affected science programs, with a view to scheduling
parts
of each as Leg 194.
Following is a site-by-site assessment of the Marion Plateau transect
for
Neogene sea level history. The conclusion is that the transect
as originally
proposed by the proponents cannot be cut, as proposed by ODP managers,
to
accomodate its inclusion with a Shatsky Rise mini-leg as a composite
Leg 194.
The scientific premise of the Marion Plateua transect is that sequential
growth
of two Miocene carbonate platforms (older: MP2; younger: MP3) atop
a stable and
subsiding basement substrate can be used to constrain a part of
the Miocene
eustatic sea-level history.
CS-01A
Objective:
1) date the onset of growth of MP2;
2) date the drowning of MP2.
Proponents: propose multiple holes to a TD of 500 mbsf
Leg 194 plan: unchanged, except the 194 plan recommends only RCB
coring and a
combined washing and sampling program below 300 mbsf. While the
Leg 194 plan
recommends sampling basement, the proponents' plan targets the
basement/sediment interface, to ascertain the initiation of growth
of MP2. That
goal cannot be abridged; continuous coring over the entire interval
is
recommended. No reduction in proposed site time.
CS-02A
Objective:
1) sampling of proximal flank facies of the MP2 platform, to basement.
Proponents: propose multiple holes to a TD of 450mbsf to assess
both the
age and
paleobathymetry of flank deposits.
Leg 194 plan: use of the MDCB or ADCB in a single hole to TD.
Recommmendation: leave the proponent plan in place; optimal recovery
is
critical
for the age/paleobathymetry objectives. These objectives are critical
to the
overall goal of assessing the history of the growth and presumed
drowning of
MP2.
CS-03A
Objective:
1) Sample flank deposits of MP2 in a downdip position, and
2) sample basinal deposits ("Megasequence C") deposits in part
derived from the
(younger) MP3. Paleobathymetry + age !
Proponents: propose multiple holes to a TD of 500mbsf to basement.
Leg 194 plan: eliminate this site.
Recommendation: leave the proponents' plan in place. Multiple penetrations
+
logs are necessary to assure a complete geologic history of the
growth of MP2,
and its stratigraphic relationship with (younger) MP3.
CS-04A
Objective:
1) Assess age control in the central basinal position between platforms
MP2 and
MP3.
Proponents: multiple holes to a TD of 600mbsf (to and through basement).
Leg 194 plan: unchanged, except that site time is reduced from
8.6 to 7.7
days.
Recommendation: leave the existing plan in place; adjust total
site time as
appropriate.
CS-05A
Objective:
1) sampling of proximal flank facies/deposits of the MP3 platform,
to basement
(including a wedge-shaped basal accumulation, "C2", that may represent
the
first clastic products of MP3).
Proponents: propose multiple holes to a TD of 500mbsf, to basement.
Leg 194 plan: use of the MDCB/ADCB in a single hole to TD, with
only spot
sampling below 300mbsf, to basement.
Recommendation: leave the proponent plan in place; optimal recovery
is critical
for age/paleobathymetry objectives. These objectives are critical
to the
overall goal of assessing the growth and presumed drowning of MP3.
CS-06A
Objective:
1) date the onset of growth of MP3,
2) date the drowning of MP3.
Proponents: propose multiple holes to 550mbsf.
Leg 194 plan: recommends only RCB coring to the same TD, with a
reduced site
time.
Recommendation: the interfaces at the crest and base (poorly imaged)
of MP3 are
critical. Multiple holes will be necessary; this site could be
shortened not to
include the basement target; if CS-05A is successful in reaching
the basement
objective.
CS-08A (CS-07A on my cross-section?)
Objective: see CS-06A
Proponents: multiple holes to a TD of 600mbsf.;
Leg 194 plan: eliminated.
Recommendation: this site might be eliminated, if the multi-hole
strategies
proposed by the proponents at CS-05A and CS-06A are successful.
CS-09A (CS-08A on my cross-section?)
Objective: compare proximal flank deposits of MP-3 (thicker on
this flank of
MP-3) with results at CS-05A.
Proponents: multiple holes to a TD of 570 mbsf, including basement.
Leg 194 plan: eliminated
Recommendation: flank deposits proximal to MP-3 differ seismically
on its two
flanks. In order to constrain the growth history of MP-3 completely,
both
CS-05A and CS-09A will be neccessary.

Attachment F: SSEP motion to SCICOM
The following motion, pertaining to communication between SCICOM
and the
SSEPs, was put forward by Julie Morris, duly seconded and passed
unanimously in the final joint session of ISSEP and ESSEP.
Resolution:
Timely and effective communication amongst SCICOM, the JOIDES office
and
the SSEPs is essential if the SSEPs are to fulfill their mandate
to
nurture proposals. Exceptional job performance by JOIDES
office
representatives, SCICOM liaisons to the SSEPs and SSEPs panelists
cannot
substitute for effective procedures that facilitate communication.
Therefore, the SSEPs make the following recommendations:
1. For proposals not ranked or below the line at SCICOM's August
meeting,
letters to proponents should be drafted by SCICOM watchdogs at
the SCICOM
meeting, and copied to the SSEP chairs and the rest of SCICOM within
one
week of the meeting.
2. Minutes from the SCICOM scheduling meeting should be made available
to
the SSEPs at the earliest opportunity, and not later than the proposal
deadline following the August meeting.
3. We strongly urge that the science plan and resulting ship schedule
be
finalized shortly after the August SCICOM meeting.
4. If SCICOM requests SSEPs input in finalizing the science
plan after
the August meeting, the first point of contact should be the SSEP
chairs. The JOIDES office must respect the responsibility
and
suitability of the SSEP chairs in choosing leaders for SSEP discussion.
5. Attendance by SCICOM liaisons to both panels at all meetings
is
essential to the SSEPs role in nurturing proposals. SCICOM
should
establish procedures to ensure effective liaison.
6. The SSEPs greatly benefit from the presence of the SCICOM chair
at
panel meetings.
