Operational again

CMRC3 was brought back online Saturday, July 23, 1100 with all instruments operational and reporting.

The second monitoring PAM fluorometer was deployed, with a new PVC housing for the distributor box and new stainless steel tubes for the sensors. After removing the first monitoring PAM unit, divers noticed pitting in one of the stainless steel sensor heads. The field crew at LSI has been requested to keep a close eye on the new system.

The deep CTD has been left off the system intentionally. The web site now reports -9 for all deep CTD values.

Each new windbird has its own magnetic compass so the direction information should be accurate. We learned the correct way to calibrate these compasses. That information will be applied to the matching instruments at SRVI1.

A site survey is planned for later this year.
