Heron Island Depth From 09 Sep 2012 To 23 Sep 2016

Temporal Range: From 09-Sep-2012 To 23-Sep-2016

Resource Summary

The 'Wireless Sensor Networks Facility' (formerly known as Facility for The Automated Intelligent Monitoring of Marine Systems (FAIMMS)), part of the Great Barrier Reef Ocean Observing System project (GBROOS), is a facility of the Australian 'Integrated Marine Observing System' (IMOS) project. This data set was collected by the Great Barrier Reef Wireless Sensor Network.

Lineage

All sensors are factory calibrated and then calibrated and serviced every six months.
The clocks on all instruments are set each night at mid-night from a central server which is turn has its clock set off an NTP server. Typical time drift in a day is a few seconds.
The clocks on all instruments are set each night at mid-night from a central server which is turn has its clock set off an NTP server. The location of all fixed equipment is recorded using a standard GPS so the accuracy should be within 5-10m using WGS-84. All mobile equipment has an on-board GPS and so should have equivalent accuracy although is will be around 10-20m due to the nature of the movement of the buoys.

Instruments are replaced and serviced at regular intervals. Each change results in a new deployment. Multiple deployments have been merged and a single data 'channel' has been created for each sensor to make it easier to access and use the data. There is a single metadata record for each channel with the deployment details for the sensor that makes up the channel described in the metadata record. Data are quality controlled by validating against a set of rules (bounds checking, etc) and then flagged using the IODE set of flags.
