submission policy data submitted to archive
within 1-year of date of collection (DOC) access
policy now follows NASA Earth Science Data
Information Policy all data publicly available
for research and education use original
contributors to be offered authorship for 3-years
of DOC contributors, NASA, and SeaBASS always to

Looking forward
new measurements, new questions new strategy
for archival? database issues physical data
management can be similar but, is SeaBASS
(cal/val driven) appropriate? new measurements
different products, questions, and goals same
archive structure, parallel structure, separate
entity? data products issues requires active
community participation expansion of expertise
(e.g., _at_ OBPG) identification of data products
(and goals) consolidation of product formats,
units, etc. other issues?

NOMAD
SeaBASS holdings post-processed and reorganized
into near-surface satellite validation and
algorithm development data set currently
consists of 3467 observations of Lw Es chl,
with ETOPO2 bathymetry and OISST Kd, IOPs, Wt,
and Sal where available absorption by
spectroscopy only, bb to be reviewed new data
products in Version 2 include POC, Kpar, and
depths of 37, 10, and 1 light levels (of
PAR) expected to be publicly released by end of
May 2008 http//seabass.gsfc.nasa.gov/cgi-bin/noma

Ocean Optics XIX
IOP Algorithm Workshop will be held in
conjunction with this years Ocean Optics XIX
Conference (Lucca, Italy) from 3-4 Oct 2008 long
term goal achieve community consensus on the
most effective algorithmic approach for producing
global scale, remotely sensed IOP
products extend the IOCCG (Algorithm Working
Group) effort to (1) dissect algorithm
components (parameterization, inversion,
optimization) to identify the most effective
method of producing global satellite products
(2) refine associated uncertainty budgets (3)
identify and remediate satellite inversion
failure conditions desired outcome community
investment in consolidated algorithm development
and routine production of satellite-derived IOP
data products

Ocean Optics XIX
participation (logistically) limited to 25
people specifically, community members with
established algorithms goal is to ensure that
participants represent spectrum of existing
approaches and relevant backgrounds workshop to
be culmination of analyses conducted from Jun to
Sep, and will focus on interpretation and
assimilation of results (with specific focus on
recently distributed series of questions) evaluat
ion data sources include NOMAD v2 and Level-2 and
-3 satellite files (e.g., SeaWiFS, MODIS-Aqua,
MERIS) Web site developed by OBPG to distribute
documentation and software and to catalog and
consolidate ongoing results
