| description | This .zip archive contains Quality Controlled float data for biogeochemical profiling floats deployed by the Southern Ocean Carbon and Climate Observation and Modeling (SOCCOM) and Global Ocean Biogeochemistry Array (GO-BGC) projects. Additional University of Washington/MBARI floats deployed outside of these programs have also been included in the archive. Data for all floats within this archive were processed by the float data management team at the Monterey Bay Aquarium Research Institute (MBARI). A comprehensive listing of floats processed by MBARI (including internal floatID, WMOID, float platform type, and program) is included within each archive. Note that historical snapshots, frozen prior to December 2022, can be found under the SOCCOM collection (https://doi.org/10.6075/J0TX3C9X).
FORMAT:
The ascii files contained herein were formatted to be compatible with Ocean Data View (ODV). Character encoding is UTF-8. ODV is freely available at https://odv.awi.de/. In addition, a Matlab function has been provided in each .zip archive for parsing the .txt files into data structures within Matlab (see get_FloatViz_data.m). Please note that the data files within this .zip archive represent a snapshot of all SOCCOM and GO-BGC float data processed at MBARI as of the date listed in the file name. Therefore, be aware that processing updates (** AND THUS CHANGES TO THE DATA **) may have occurred since the time the snapshot was created. For the most up-to-date files (processed every 4 hours), visit https://ftp.mbari.org/pub/SOCCOM/FloatVizData/ or https://www.mbari.org/science/upper-ocean-systems/chemical-sensor-group/floatviz/
ALTERNATE FORMATS: NetCDF and Matlab
Matlab and NetCDF formatted files are provided for each ODV text file. The Matlab format is loaded as structure, FloatViz, with the ODV parameter names as the structure's fieldnames. The NetCDF format is similar to ARGO Float NetCDF format in its structure. The parameter names and flagging, however, match the ODV text parameter names. In addition to the quality control flag string entries, a numeric array of quality control flags is provided in the NetCDF files for programming convenience. Additionally, note that an explanation of Quality Flag Identifiers is included in each alternate format file.
QUALITY CONTROL DOCUMENTATION:
Delayed-mode quality control (DMQC) of biogeochemical float data within this archive is performed routinely by data managers at MBARI following Maurer et al (2021), https://doi.org/ |

QUALITY CONTROL DOCUMENTATION:
Delayed-mode quality control (DMQC) of biogeochemical float data within this archive is performed routinely by data managers at MBARI following Maurer et al (2021), https://doi.org/10.3389/fmars.2021.683207. QC notification emails are currently being sent out periodically to inform users of key updates to processing, QC and/or sensor calibrations for specific floats. All QC emails as of the date of this snapshot are included in each downloadable zip file.
PARAMETERS:
For information pertaining to float identification, sensor arrays, data parameters, and quality control please refer to descriptions within the file headers. Each snapshot within this collection includes estimated total alkalinity and derived carbon parameters for DIC and pCO2 using one of two algorithms (LIAR or CANYONB). Floats without a pH sensor will not have these additional parameters within their respective data files. See file headers for details. Additionally, files located at the urls listed above will include carbon parameters derived using observed pH and total alkalinity estimated by the LIAR method. All carbonate system variables calculated with CO2SYS for Matlab (Sharp et al., 2020; see also Lewis and Wallace 1998) used the following conditions: pH was reported on the total scale. K1 and K2 dissociation constants were from Lueker et al., 2000, doi:10.1016/S0304-4203(00)00022-0. The KSO4 dissociation constant was from Dickson, 1990, doi: 10.1016/0021-9614(90)90074-Z. The KF dissociation constant was from Perez and Fraga 1987, doi: 10.1016/0304-4203(87)90036-3. The borate to salinity ratio was from Lee et al., 2010, doi:10.1016/j.gca.2009.12.027. Silicate and Phosphate were not measured by the float, but estimates based on Redfieldian ratios improved the carbonate system estimates. If a nitrate value was considered to be of good quality silicate = nitrate*2.5 and phosphate = nitrate/16, otherwise the best estimate for both was considered to be 0. When pCO2 was estimated from TALK_LIAR and pHinsitu, a bias was first added to pH (25C,0dbar) following Williams et al., 2017, doi: https:doi.org/10.1002/2016GB005541 , section 3.4, equation 3. This correction is not necessary for DIC and DIC is computed with the reported pH and the TALK_LIAR value.
RESOLUTION:
This archive contains both low resolution and high resolution data. The format is defined by the folder name: SOCCOM_GO-BGC_LoResQC_METHOD_ddmmmyyyy or SOCCOM_GO-BGC_HiResQC_METHOD_ddmmmyyyy (where METHOD = LIAR or CANYONB). Note that for APEX floats, the low resolution files only report data at depths where biogeochemical sensors sample, while the high resolution files merge this low resolution data with higher resolution pressure, temperature and salinity data (sampled every two meters in the upper 1000 meters). Be aware that, due to the merging of the two separate sampling schemes by interleaving the LowRes samples into the HiRes sample structure, HiRes files could potentially contain separate sets of samples with duplicate pressure values. For Navis floats all biogeochemical sensors except nitrate are sampled every 2 meters in the upper 1000 m. Additionally, all Navis float data is contained in both the LoRes and HiRes archives (per user request).
DISCLAIMER:
These data are provided as-is. We do our best to provide high-quality, complete data but make no guarantees as to the presence of errors within the data themselves or the algorithms used in the generation of derived parameters. It is the user's responsibility to ensure that the data meets the user's needs. However, please report any observed discrepancies in the data to the contact listed below and we will do our best to fix them.

This archive contains both low resolution and high resolution data. The format is defined by the folder name: SOCCOM_GO-BGC_LoResQC_METHOD_ddmmmyyyy or SOCCOM_GO-BGC_HiResQC_METHOD_ddmmmyyyy (where METHOD = LIAR or CANYONB). Note that for APEX floats, the low resolution files only report data at depths where biogeochemical sensors sample, while the high resolution files merge this low resolution data with higher resolution pressure, temperature and salinity data (sampled every two meters in the upper 1000 meters). Be aware that, due to the merging of the two separate sampling schemes by interleaving the LowRes samples into the HiRes sample structure, HiRes files could potentially contain separate sets of samples with duplicate pressure values. For Navis floats all biogeochemical sensors except nitrate are sampled every 2 meters in the upper 1000 m. Additionally, all Navis float data is contained in both the LoRes and HiRes archives (per user request).
