## SeaBASS status report

- MODIS Science Team meeting
- 4 - 6 Jan 2006
- Baltimore, Maryland
- Jeremy Werdell
- NASA Ocean Biology Processing Group & SSAI

## 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 *****R******rs*****(********) and *****C******a*****, plus dates and locations**
**also includes *****T*****, *****S*****, *****K******d*****(********), *****b******b *****(********), *****a******d *****(********), *****a******g *****(********), 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***

**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**

## NOMAD: coastal data

## 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 CFC’s, 14C, etc.)
- Primary Production (PP)
- Sea Surface Temperature (SST)
- Other
- Protocol development

## 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.
