Marine Nearshore Characterization (319)
Problem: Need accurate characterization of nearshore habitat types in both the intertidal and subtidal zones
Project Activity Scope (from Technical Overview Chart): Measurement and Analysis Method Development through Measurement and Analysis System Applications
PNNL Solution:
- Use Compact Airborne Spectrographic Imager (CASI) to obtain intertidal habitat delineation
- Use georeferenced underwater video to characterize habitat in the subtidal and lower intertidal zones
- Sufficient resolution and precision (position and habitat classification) allow integration of the two data sets
Capabilities Employed to Meet Client Needs: Marine field study planning and execution; georeferenced underwater video data collection; aerial imagery data provided by project collaborator; ground-truth data collection during CASI flights with hand-held radiometer, analysis of georeferenced data sets from both characterization methods; data set comparison and integration in the overlap data in the lower reaches of the intertidal zone; prepared fully integrated maps for the study area that enhanced assessment of eelgrass habitat over a range of water depths unobtainable through conventional, single methods.
