Mooring maintenance

Project Manager: Mike Kelley

MBARI moorings represent state-of-the-art systems for the collection of concurrent time series of physical, chemical and biological properties. The suite of sensors currently supported include meteorological (wind speed and direction, air temperature, relative humidity, irradiance), physical oceanographic (temperature, salinity, horizontal currents), chemical (carbon dioxide, nitrate) and biological (backscatter, fluorescence, radiance and irradiance). 

This project continues the time series observations begun in 1989. The major milestones in 2005 will be the mooring turnaround dates with the tentative schedule of M2 in April and M1 in October. In addition, the Center for Integrated Marine Technologies (CIMT or M0) turnaround is scheduled for early July. 

For the 2005-M1 deployment, the Mooring Users Committee requested improving the anti-fouling performance of the upper Microcats by using new, Pumped Microcats at 10, 20, and 40 meters. Also requested for M1:  surface oxygen sensors and a deep CTD at 200 meters with auxiliary sensors to characterize the downward flux of particulate matter. A vertical profiler at M1, capable of descending to 200 meters, could satisfy the deep CTD requirement. Periodic maintenance trips to M0, M1 and M2 will be scheduled every 2-3 weeks.
