Ridge-to to-Reef Assessment of Land-based Pollution Impacts on Nearshore Pacific Coral ReefsPIERC Project Leader: Jim Jacobi, Ph.D. (w/ Pat Chavez, Mike Field, Barry Hill and Jon Stock) |
 |
Objectives: Quantify terragenic sediments on reefs in multiple locations on high islands Evaluate watershed ecosystems for sediment sources, transport, and causes Develop sedimentation model that links terrestrial and marine ecosystems with resource management options |
| Accomplishments: Measured magnitude and residency patterns of sediments on reefs Acquired and evaluated > 8,000 aerial images of watersheds and reefs Determined daily discharge of fresh water and sediment to coastal waters Initiated studies of sediment and algal impacts on coral physiology and changes in marine communities over time |
Significance: Multidisciplinary support to DOI leadership on U.S. Coral Reef Task Force land-based pollution objectives Active participation of resource managers and community stakeholders in shaping objectives and metrics Knowledge, methods, and technology can be applied to other DOI objectives |
