PRV Committee Meeting
May 5 & 6 May, 2011
Rob Dunbar, PRV Chair opened the meeting at 0900 with review of what we had accomplished thus far and the goals of the next two days. The PRV committee will work towards submitting a draft/interim report to NSF in June 2011.
Hugh Ducklow brought us up to date on activities of the National Academy Research Board as it relates to our efforts. The academy report is on a fast track with the second draft scheduled to be submitted by end of May. It will then be reviewed and finished by end of September.
In the ocean atmospheric section there will be a series of recommendations as defined by the science questions for next 20 years. They did a survey and results showed they need observing platforms. Blue Ribbon will follow the NASB study.
Polar Research Board- Hugh also on this, report coming out any day now. Also the Consortium for Ocean Leadership’s Working Group report will tie into this and will be made public in a week.
The Polar Research Vessel will be bipolar, serving both
One of the goals of this meeting is to develop and finish a one page polished document on each discipline.
Larry Lawver has been doing research on coring and provided an overview and feedback from Conoco on moonpools. Apparently in industry a 4m by 4 m moonpool is standard.
Larry also reviewed various coring systems such as:
Question was asked on how far should we go to make the ship capable of coring?
Larry- I think it is critical to answer science questions at hand.
Carin- Are their science drivers requiring winter conditions?
Larry- If you are doing a complicated science ops, having the ice will help keep ship
Carin – this is an operational issue, not a science driver.
Rob- we are talking about access to 50-100 meter depth cores.
Basic question- if you want an icebreaker to work in the ice, you need a moon pool.
per Dan Oliver.
Carin – Having a moon pool, it needs to be fully capable for everything, ctd’s, net tows,
Niskins casts, but also be able to also use a Baltic room. So it would be a combination
moon pool inside a Baltic Room.
Rob- I think we are in agreement that we want a interior moon pool. This is a substantial change from the 2006 study. On the order of 4 X 4 meter square.
There will be mission specific cases where we can’t use this ship, ie. Joides Resolution might need to be brought in . We need to call out examples of cases where we know this ship can’t do everything.
Core Lengths- 50 meter for long core, 100 meter for prod drill type.
On the moon pool issue, Dan Oliver and Doug Russell will collaborate
on this and on coring, Larry and
McMurdo Breakout- we recommend that this ship not be used to perform McMurdo
Helicopters- Dan Oliver and Doug Russell will write-up a draft report on this.
Special Purpose Science- There will be times when we need a special purpose vessel.
Ice Coverage- We need a figure in the report for sea ice
extend and thickness in both the
Frontiers- there is a need for comparative science to be
done for both
Operators- Will this be a UNOLS versus a commercial operator. This question will need further investigation.
Conference room –
Power compatibility of multi—national powered equipment from foreign countries.
6 May 2011- Meeting Commenced at 0830
General discussion on the report followed.
Ask Alex- about how she wants final copy of the report to look, That is does she want color, with nice pics?,, binding. See Alex’s e-mail on 6 May 2011
Rob asked each discipline leader to make sure science questions are
