Seafloor/Habitat Data Access Catalog
High resolution multibeam bathymetry data collected and processed by the Seafloor Mapping Lab is distributed to partners and the wider research community for use in ecological modeling, coastal conservation, baseline habitat maps, etc. The group is developing an online portal via Google Earth interface in addition to its existing direct data download capabilities.
Important: If you are using imagery posted as kml files in the CSMP Data Catalog, please be aware that we discovered a positional offset between these images and the underlying GE terrain (although both were created from the same source data). The positional errors, which vary from image to image, occurred during conversion from ArcGIS GRID to kml format. Most of these problem kmzs have been reconverted to positionally-correct versions using a more robust method and are now available. There are a minute number of files that could not be updated; however, these shifted-image kmls will remain available for visualization purposes. If you have additional questions, please contact email@example.com
Note: The Google Maps interface may unexpectedly omit the scrollbar in the survey placemark balloons. If this tool is not available and the data list is truncated, please go directly to the SFML Map Locator [to access data tables], or open the SFML survey kml in Google Earth to download the data. Additionally, the data maps/TOC list may exceed a single page. To view all surveyed regions, click on "view catalog in larger map" and scroll to the bottom of the page for multiple page links.

How to View or Download Data
For each survey you may (1) download data directly from the SFML Data Library, or (2) view specific data files in Google Earth. Data products include high-resolution multibeam bathymetry and backscatter imagery, generalized habitat interpretations, bathymetric soundings and contours, survey tracklines, and FGDC metadata.
The data available for each region is shown on the map as survey footprint polygons (squares). Yellow squares mean the data link is not active at this time, orange squares indicate an active infromation/download link. Click on the data "blocks" for the list of data and viewing options. At this time, only multibeam bathymetry images are available in KMZ format and can be selected and viewed in Google Earth. The grayscale and depth-colored images are large files and may take time to load.
- Clicking on a data block will open a download menu. When selecting a file from the menu you will be prompted to either save the file (zip or KMZ formats) or open it in Google Earth (KMZ). There may be mulitple survey locations listed within a single block.
