Welcome to the SeaWiFS Bio-optical Archive and Storage System (SeaBASS), the publicly shared archive of in situ oceanographic and atmospheric data maintained by the NASA Ocean Biology Processing Group (OBPG). For information on how to search for data, please refer to the "Get Data" menu options. For information about preparing files for submission to SeaBASS, refer to "Contribute Data."

Sat-v-Sat Search Modified

Satellite-to-satellite validation searches now only return results with coincident in situ measurements. The functionality to compare different satellites or processing versions, with or without in situ data, will return in future updates in the form of a timeseries search.


Angstrom Exponent Validation Now Available

Satellite validation matchups for AERONET Ocean Color stations to SeaWiFS, MODIS Aqua, MODIS Terra, and VIIRS of the Angstrom Exponent for AOT(443nm) to AOT(865nm) are now available via the SeaBASS Validation Search Engine.


Website updates: New Navigation Bar and Data Search

We at SeaBASS have recently updated a few layout and navigation features of our website. The most noticeable update is the new main navigation bar, which has been reorganized to better display and group similar topics. You will now find all SeaBASS data access tools (Data Search, Browse Archive, Validation Search, etc) under the new Get Data drop-down menu.

All relevant resources for data submitters may now be found under Contribute Data, including links to the list of standard SeaBASS metadata headers and fields and units.

We have also consolidated relevant SeaBASS database listings under the Lists drop-down menu, including sorted lists of SeaBASS experiments, cruises, submitting investigators and their affiliations, and recent data updates.

Additionally, all SeaBASS Data Search pages have undergone minor reorganization to simplify the process of finding data within the SeaBASS archive and validation system.


New Search Feature: Optically Shallow Measurements Flag

If SeaBASS files are known or suspected to contain optically shallow conditions -- non-negligible bottom reflectance, they are flagged with the metadata header "/optical_depth_warning=true". By default, these files are excluded from file search results. Use the "Yes" or "Exclusively" options under the File Search tab of the Data Search to include these data in your search results.


New Search Feature: Search and Preview Benthic Imagery

SeaBASS now supports the archiving of imagery data associated with a SeaBASS file. One recent addition of this kind of data to SeaBASS are benthic cover photo-mosaics as part of the CORAL project. To search for these kind of data, visit the Data Search and select the "Benthic Imagery" check box under the "Include Associated Files" section of the File Search tab. In the search results, there will be an image icon to the right of the file name if a SeaBASS file has associated image. Click the icon to preview the image. Note: you will likely need to check "Yes" under "Include Optically Shallow Measurements" on the Data Search page to find these SeaBASS files and images.


New Search Feature: Find Multiple Measurements if Co-located

By popular demand, a new option has been added to the File Search to find multiple specific measurements located together (by cruise). To use it, visit the File Search tab under the Data Search and select "Find files where all the specific products entered below were measured in the same cruise." In the search bars beneath, type in multiple products, 1 per search bar (e.g., "Rrs" and "ag").


New Database, New Website

We've completely redone our database and have updated the website accordingly. It should be a bit quicker and more reliable and, though highly tested, small features and bugs tend to slip through the cracks. Just notify the SeaBASS administrator of any oddities and we'll check it out ASAP.


New Software Tools

netCDF converter: sb2nc is a Perl script designed to convert SeaBASS format data files to netCDF4 files.

Python SeaBASS file reader: While many of Python's built-in functions may be used to read SeaBASS files, this module leverages Python libraries and tools, including NumPy and Ordered Dictionaries, to efficiently read, sort, mask, and return the contained data for easy use.



FCHECK now outputs a summary of the different types (and number of occurrences) of errors and warnings that were found during its scan. This summary should make it easier for users to identify problems when they have checked multiple files and there is a lengthy amount of output to read through.


Processing Version Labels

The validation search results and stats download now include the actual processing version used to produce the extracts.
