Sensor Information for UMOOS Mooring: N0120

Mooring History:

Date	Buffer Name	Data Type	Depth	Comments
2016-07-24 16:05	ALL	ALL		Redeployed by R/V Connecticut.
2016-09-07 06:30	goes	ALL	0	Last backup Goes transmission received (primary iridium communicatios working properly).
2016-09-22 20:00	goes	ALL	0	Backup Goes transmissions resumed from this buoy (Goes GPS positions being received again).
2017-02-13 22:00	ALL	ALL	0	Buoy moved 500m to NW during a storm (peak winds 24 m/s, waves 7m, surface currents 1.4 m/s).
2017-03-01 00:00	ALL	ALL	0	Problems connecting to the buoy using iridium have continued for several periods this winter (may be related to cold temps?). Normal communications have typically been restored after 1-5 days.
2017-04-11 01:00	suna	ALL	50	Last data received from 50m SUNA nitrate sensor.
2017-04-30 04:00	sbe37	conductivity	1	Surface conductivity sensor failed (reads too low, near zero)
2017-05-01 01:00	sbe37	ALL	20	Last data received from 20m SBE37IM.
2017-07-15 05:00	ALL	ALL	0	Buoy is no longer anchored and is presently adrift.
2017-07-27 16:30	ALL	ALL		Buoy and instruments recovered by M/V Megan T Miller.
2017-07-27 20:00	ALL	ALL	200	Acoustic release and float recovered from anchor site by M/V Megan T Miller.

Notes: Sensors highlighted in red indicate problems with this sensor during deployment. Depth is measured relative to the ocean surface with positive depths indicating depths below the ocean surface. Negative depths are heights above the surface. In the case of doppler current measurements, the depth indicates depth of first measurement:delta-depth:depth of last measurement. For instance, 10:4:106 represents currents measured every 4 meters from 10 meters down to 106 meters (28 depths in all).
