Abstract:

The long-term goal of our research is to improve our ability to observe the oceans plants, animals, and their physical and chemical environment at the scales that control how they live, reproduce, and die. We are working with our colleagues in the ONR-sponsored research program on Layered Organization in the Coastal Ocean LOCO to jointly analyze data collected in Monterey Bay, CA during FY2002, 2005 and 2006. Our work this year has involved data analysis, presentation of our results at several scientific meetings, and the preparation of publications. During the late summer and early fall of 2005 and 2006, very thin layers of phytoplankton, zooplankton, and water column physical structure were studied by a part of the LOCO research team at several closely spaced shallow, near-shore stations in northeastern Monterey Bay. Other team members examined larger scale horizontal distributions and temporal thin layer patterns in deeper water nearby, while still others collected plankton and made measurements of turbulence, nutrients and various optical properties of the water column. Our part of this research involved the deployment of several acoustic and ancillary sensors on the seabed. The acoustic sensors were used to describe the distributions of small zooplankton, micronekton and small gas bubbles. Other LOCO principal investigators also used a variety of sensors to examine thin layers and the conditions and processes that led to their formation and destruction during each of the field periods in Monterey Bay. We have been analyzing and sharing our data, comparing it to measurements made by our colleagues, making presentations at technical meetings, and submitting papers for publication.
