.nc files from deployments 2, 3, 5, and 6 are missing the pressure coordinate. As far as I can tell, this usually happens when there is no collocated CTD data. Pressure should always be a coordinate, and if there is no collocated CTD this coordinate should be an array of NaNs. The system currently only looks for collocated CTD data for the same delivery method (here recovered_host). The system should use the recovered_inst CTD data to calculate the dissolved oxygen L2 data product if recovered_host isn't available.

Daily DO spikes starting in Feb 2014 for this deployment suggest biofouling. Excluding from summary data ranges.

Annotation ID 709 "Short deployment due to the fuel cell not functioning correctly" should be updated to indicate that this refers to deployment 2, and data aren't expected from most instruments for this time period.

Deployment: 3

There are no data from the collocated CTD for deployment 3 (the instrument failed at deployment, no deployment 3 CTD file in thredds): https://opendap.oceanobservatories.org/thredds/catalog/ooi/lgarzio@marine.rutgers.edu/20190328T170120-CP01CNSM-RID27-04-DOSTAD000-recovered_host-dosta_abcdjm_dcl_instrument_recovered/catalog.html. However, there is temperature, pressure and salinity data in the deployment 3 DOSTA file for a few days in Oct 2015: https://opendap.oceanobservatories.org/thredds/dodsC/ooi/lgarzio@marine.rutgers.edu/20190328T170120-CP01CNSM-RID27-04-DOSTAD000-recovered_host-dosta_abcdjm_dcl_instrument_recovered/deployment0003_CP01CNSM-RID27-04-DOSTAD000-recovered_host-dosta_abcdjm_dcl_instrument_recovered_20150507T174515.211000-20151023T193331.593000.nc.html.
