Deployment 2: Mooring was blown down by ~500m. Corresponds to the presence of eddies in the region based on altimetry imagery.

There is no pressure variable in the deployment 1 .nc file. This should be a coordinate.

In Jan - Feb 2016, the signal of a colder, fresher water mass appears to be captured by several CTDs on GA03FLMA and GA03FLMB. Salinity and density drop suddenly for several days. This appears to be a real event as the phenomenon is captured by multiple instruments located on two moorings, but should be further investigated. Density and salinity drop suddenly on the following CTDs:
GA03FLMA-RIM01-02-CTDMOG044
GA03FLMA-RIM01-02-CTDMOG045
GA03FLMA-RIM01-02-CTDMOG046

Suspect data due to calibration error - annotation ID 433 needs to be updated when the issue is resolved.
