Sensor Information for UMOOS Mooring: A0137

Mooring History:

Date	Buffer Name	Data Type	Depth	Comments
2017-06-28 00:50	ALL	ALL		deployed by the Warren
2017-06-28 01:00	sbe16	dissolved_oxygen	50	Dissolved oxgyen sensor at 50m failed (voltage reading of zero volts).
2017-06-28 01:00	met	wind_speed,wind_gust	-4	Backup wind speeds too high at minutes 50 and 00. During the rest of the hour, the backup wind speeds compare well to those measured by the primary wind sensor.
2017-06-28 01:00	met	visibility	-3	Visibility readings flagged as invalid (intermittent periods when values seem to be tracking buoy battery).
2017-06-28 01:00	aanderaa	percent_oxygen_saturation	2	Optode reading too low/erratic.
2017-07-04 17:00	met	wind_speed,wind_gust	-4	New program loaded into control box remotely; valid backup wind data being received after GPS sampling time was shifted.
2017-07-07 17:00	sbe16	ALL	50	SBE16+ inadvertently taken out of sampling mode
2017-07-10 22:00	sbe16	ALL	50	SBE16+ sampling resumed after instrument talk-through to restart sampling.
2017-07-17 16:45	suna	ALL	20	Last data received from 20m SUNA nitrate sensor. Talkthrough to instrument indicates instrument is in adaptive mode sampling due to reduction in light (possible biological fouling).
2017-07-23 08:00	suna	ALL	20	Data transmissions from 20m SUNA nitrate sensor have resumed
2017-07-26 23:00	diagnostics	gps_lat,gps_lon	-3	Last valid data received from primary GPS; backup Goes GPS still working properly.
2017-08-10 18:00	suna	ALL	20	Data transmissions from 20m SUNA nitrate sensor have stopped once again.
2017-12-07 16:42	ALL	ALL		recovered by the R/V Connecticut

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).
