Dataset: Depth profiles from Seagliders 146, 147, 148, 511, 512, and 626 in a total of 18 missions at Station ALOHA in the North Pacific Subtropical Gyre from 2008-2023

This BCO-DMO dataset page contains supporting metadata and CSV formatted datasets for seaglider deployments from 2008 to 2023. Additional NetCDF formatted datasets, containing parameters in the CSV formatted datasets along with raw data and QC values, for seaglider deployments from 2008 to 2023 are available at Zenodo, DOI: 10.5281/zenodo.10416616. See the “Related Datasets” section.

All the seaglider deployments dataset files have the same parameters which are defined on this dataset page. Individual seaglider deployments did not measure all of the parameters, though, e.g. either bbp650 or bbp660, and in that case, values are left blank for unmeasured parameters. 

Parameters in common with the NetCDF formatted datasets and the CSV formatted datasets are: ISO_DateTime_UTC, lat, lon, depth, divenum, direction, temp, cond, salin, sigma, oxygen, chla, bbp470, bbp470_spikeflag, bbp650, bbp650_spikeflag, bbp660, bbp660_spikeflag, bbp700, and bbp700_spikeflag.

Parameters specific to the CSV formatted datasets are: seaglider_deployment, seaglider_platform, and seaglider_mission.

Additional parameters included in the NetCDF files are pressure, pitch, raw data, chla_spikeflag, and QC flags: press, pitch, oxygen_raw,  chla_raw, chla_spikeflag, bbp470_raw, bbp650_raw, bbp660_raw, bbp700_raw, temp_qcflag, cond_qcflag, salin_qcflag, sigma_qcflag, oxygen_qcflag, chla_qcflag, bbp470_qcflag, bbp650_qcflag, bbp660_qcflag, and bbp700_qcflag

The supplemental file seaglider_deployments_metadata.csv contains the locations and dates of each seaglider deployment and recovery via ships and small boats along with the locations and dates of data collection for each seaglider deployment. Additional metadata columns with flags of True or False were included to indicate if the following parameters are measured in an individual deployment dataset: oxygen, bbp650, bbp660, and bbp700. These flag columns were added because deployments either measured bbp650 or bbp660, and oxygen and bbp700 are not always measured during a deployment.  All the seaglider deployments dataset files have the same parameters to enable datasets to be more easily queried and combined programmatically.
