* UPDATED, 2019-01-15: After careful review, the original data product algorithm (pco2_pco2wat) for this sensor was found to contain an error that resulted in calculation of incorrect derived L1 pCO2 values. In consultation with the vendor, the algorithm has been corrected, verified, and uploaded to the OOI system. This update, effective 2019-01-10, applies to all deployments for this sensor. All derived L1 pCO2 data products generated prior to this date should be re-requested in order to ensure utilization of the correct algorithm. The updated algorithm can be viewed at https://github.com/oceanobservatories/ion-functions/blob/master/ion_functions/data/co2_functions.py. *

Until further notice, derived L1 pCO2 data products from this sensor are incorrect and should not be used. A significant discrepancy has been uncovered between the pCO2 values from shipboard water samples vs. values calculated by OOI system. The pco2_pco2wat algorithm is under review and can be viewed at https://github.com/ooici/ion-functions/blob/master/ion_functions/data/co2_functions.py.

On Wednesday Aug 22 2018, an automatic protective shutdown of primary power to the OOI Cabled Array occurred during installation of a new chiller system. Power was restored on Aug 24. Due to loss of power to the Cabled Array marine infrastructure, data were not collected by the instruments.

There is no pressure variable in any of the .nc files. This should be a coordinate.

Annotation ID 90 needs to be updated when the cal value review is complete.

By Lori Garzio, on 11/14/19


When I downloaded data for deployments 1-4 for this instrument (pco2w_b_sami_data_record), I don't receive data files for deployments 2 and 3 (there are files for pco2w_b_sami_data_record_cal). This should be investigated and annotated if there is a reason the science data aren't available.


By Lori Garzio, on 11/14/19


100% of the pco2_seawater values are outside of global ranges for deployments 1 and 4 (data aren't available for deployment 2-3) - the global ranges should be updated to be from 200-2000 uatm
