Multi-disciplinary Ocean Sensors for
Environmental Analyses and Networks (MOSEAN)

Ocean Physics Laboratory
Multi-disciplinary Ocean Sensors for
Environmental Analyses and Networks (MOSEAN)

The MOSEAN project is funded by the National Oceanographic Partnership Program (NOPP). The main goal of MOSEAN is to develop and test relatively small, lightweight optical and chemical sensors for autonomous deployment. Real-time data telemetry will also be implemented. Two field sites are planned for the MOSEAN project:
(1) Santa Barbara Channel in <25 m water depth (CHARM mooring) and
(2) Pacific Ocean near Hawaii >4000 m water depth (HALE-ALOHA mooring).

The first, second, and third deployments of the CHARM mooring have been completed (May 19 - October 2, 2003; February 10 - May 5, 2004; and May 15 - September 21, 2004). The next SB CHARM deployment is scheduled for February 2005. New instruments for testing and transitioning include spectral backscattering and spectral fluorescence sensors, and chemical sensors for macro and micronutrients. Complementary data are also collected from other instruments (see mooring diagram). Scientific goals in the SB Channel include investigation of particulate dynamics through optics, optical and chemical detection and characterization of harmful algal blooms, and effects of physical processes on chemical and bio-optical properties.

The HALE-ALOHA mooring was deployed in August 2004 (see mooring diagram) and will be recovered and redeployed in November 2004. The location of the mooring is near the existing HOT site.

MOSEAN Co-PIs include Casey Moore (WET Labs, Inc.), Al Hanson (SubChem and U. Rhode Island), and Dave Karl (U. Hawaii).
