2

• a busy year
• the NASA bio-Optical Marine Algorithm Data set
  (NOMAD) released
• and, a not so busy year
• rate of data submission still in decline
• no major updates to the archive, database,
  search engines, or validation software

NOMAD

• SeaBASS remains the NASA archive for in situ
  bio-optical data
• NOMAD is a standalone product developed using the
  data archived in SeaBASS
• data post-processed to remote-sensing relevant (
  surface) values
• release 1 includes 3,467 coincident observations
  of Rrs(?) and Ca, plus dates and locations
• also includes T, S, Kd(?), bb (?), ad (?), ag
  (?), and a? (?), when available
• a(?)s from spectroscopy only
• full data set with search engine publicly
  available via
• http//seabass.gsfc.nasa.gov/cgi-bin/nomad.cgi
• data preparation described in
• Werdell, P.J. and S.W. Bailey, 2005, Remote
  Sensing of Environment, 98, 122-140
• http//seabass.gsfc.nasa.gov/data/werdell_nomad_
  iop_qc.pdf
• featured in the Ocean Color Bio-optical Algorithm
  Mini-workshop (OCBAM)
• conducted at the University of New Hampshire, Sep
  2005

data access policy

• reviewed and accepted at the 2004 MODIS Science
  Team meeting
• full access limited to NASA OCRT members and
  voluntary data contributors
• voluntary contributor status reviewed annually
• data released publicly on 3-year collection
  anniversary
• contributors may opt to release data early
• contributors extended authorship rights until
  3-year collection anniversary
• users asked to acknowledge contributors,
  SeaBASS, and NASA

Road Map for next generation

• Inventory of the oceanic parameter measured
  data submission (AOPs, IOPs, HPLC, etc.)
• Revision of the required and highly desired
  in situ observations for ocean color system
  validation, and algorithm validation through an
  open community participation
• Future parameters for the SeaBASS/NOMAD could be
• Carbon data set measurements (dissolved inorganic
  carbon, dissolved organic matter, particulate
  organic matter, calcite, alkalinity, T, S,
  nutrients, O2, and related tracers such as CFCs,
  14C, etc.)
• Primary Production (PP)
• Sea Surface Temperature (SST)
• Other
• Protocol development

23
NASA policy requires data submission to SeaBASS

• Submission Ocean color algorithm development and
  new products are essentially observation limited,
  and rapid turnaround and access to such data are
  crucial for progress.
• Formats and Metadata Data should be provided in
  the currently agreed-upon format, along with
  relevant information describing collection
  conditions, instrument specifications, instrument
  performance and calibration, and statements of
  data accuracy. The currently used data format
  specifications and examples are posted on the
  SeaBASS Web site. The provider should use FCHECK,
  which is an automated format checker program, to
  test the format validity of SeaBASS data files
  via return e-mail.
• Use Conditions Prior to the three-year data
  collection anniversary, users of data will be
  required to provide proper credit and
  acknowledgment of the provider. A citation should
  also be made of the data archive. Users of data
  are encouraged to discuss relevant findings with
  the provider early in the research.
