With this amendment to ROSES-2005, and for the reasons explained below,
NASA postpones the call for proposals in the three Ocean Biology and
Biogeochemistry programmatic element topics associated with the Remote
Sensing Science for Carbon and Climate program described in Appendix A.7 of
ROSES-2005. The solicitation for proposals under the other four
programmatic element topics listed in Appendix A.7 of ROSES-2005 remains
unchanged. In particular, there is no change in due dates for Notices of
Intent (NOIs) or for proposals. Notices of Intent to propose are still due
June 3, 2005, and proposals are still due August 3, 2005. There is also no
change in the anticipated funding available to support the selection of new
investigations within this program element.

On or about June 8, 2005, Amendment No. 18 to NASA Research Announcement
"Research Opportunities in Space and Earth Sciences" (NNH05ZDA001N) will be
posted on its homepage Web site at http://nspires.nasaprs.com/ (select
"Solicitations" then "Open Solicitations" then "NNH05ZDA001N").

The Remote Sensing Science for Carbon and Climate program described in
Appendix A.7 of ROSES-2005 is postponing the call for proposals under three
of its seven programmatic element topics.

Selections for the 2004 Oceans and Ice NASA Research Announcement
(NRA-04-OES-02) are being announced this month. In order to allow NASA and
the research community to appropriately respond to this announcement, the
solicitation of proposals in related areas of Ocean Biology and
Biogeochemistry will be postponed.

Proposals are no longer solicited in the following three programmatic
element topics of Appendix A.7 of ROSES-2005:
- Global Ocean Carbon / Particle Abundance,
- Coastal Ocean Carbon, and
- Global Air-Sea CO2 Flux.

A new proposal due date for the postponed Ocean Biology and Biogeochemistry
programmatic element topics will be announced as a new program element in
the ROSES-2006 NASA Research Announcement. ROSES-2006 will be released in
late January 2006; proposals will be due no earlier than 90 days after the
release.

The solicitation for proposals under the other four programmatic element
topics listed in Appendix A.7 of ROSES-2005 remains unchanged. In
particular, there is no change in due dates for Notices of Intent (NOIs) or
for proposals. There is also no change in the anticipated funding
available to support the selection of new investigations within this
program element.
