Changes in version 2.4.0.9000                      

  - Added DOP water quality data.
  - Updated baystudy dataset.

                        Changes in version 2.4.0                        

  - Added temperature and conductivity to USGS_CAWSC
  - Added DO and pH data to all surveys that collect this data.
    USGS_SFBS collects both calculated (from a sensor) and discrete DO,
    so we used discrete DO up to 2016 and calculated DO afterwards to
    mirror the methodological change that occurred in the EMP survey
    in 2016.
  - Updated to newest EMP data with some historical data issues fixed.
  - Added NCRO laboratory and water quality data
  - Added bottom conductivity to twentymm, baystudy, SDO, FMWT, and STN
  - Added turbidity to EMP, FMWT, and STN
  - Fixed timezones for SDO data. SDO times are reported in PST but had
    incorrectly been imported as local time (PST/PDT). Now, they are
    imported as Etc/GMT+8 and then converted to America/Los_Angeles to
    correspond to the other surveys.
  - Updated STN, FMWT, EDSM, DJFMP, SLS, Suisun, EMP, USGS_SFBS,
    USGS_CAWSC, YBFMP, SKT, 20mm, baystudy, and SDO datasets
  - Removed rows from FMWT and STN datasets that did not contain any
    water quality information

                        Changes in version 2.3.2                        

  - Fixing error where YBFMP Secchi data was in meters. Converted it to
    cm for consistency with other surveys.
  - Adding Secchi_estimated variable to FMWT data

                        Changes in version 2.3.1                        

                        Changes in version 2.3.0                        

  - Changed the name of the USGS survey to USGS_SFBS to avoid confusion
    with the new USGS_CAWSC survey.
  - Added USGS_CAWSC data.

                        Changes in version 2.2.0                        

  - Add reporting limits (RLs) to EMP data.
  - Updated STN data to newest version with 2021 data

                        Changes in version 2.1.0                        

  - Added nutrient data to EMP and USGS datasets.

                        Changes in version 2.0.0                        

  - Added the Yolo Bypass Fish Monitoring Program data
  - Added Stockton Dissolved Oxygen survey as an additional data source
  - Removed duplicated water quality data from suisun data
  - Added Smelt Larva Survey as an additional data source
  - Tweaked the wq function interface to force users to specify data
    sources, in preparation for adding more sources.
  - Updated the DJFMP, EDSM, EMP, FMWT, SKT, STN, USGS, 20mm, Suisun
    datasets to their latest version

                        Changes in version 1.1.0                        

  - Fixed timezones for EMP data. EMP times are reported in PST but had
    incorrectly been imported as local time (PST/PDT). Now, they are
    imported as Etc/GMT+8 and then converted to America/Los_Angeles to
    correspond to the other surveys.

                        Changes in version 1.0.1                        

                        Changes in version 1.0.0                        

  - Publishing to link with data publication.

                        Changes in version 0.2.0                        

  - Fixing one tide value of 0 from SKT by converting it to NA.

                        Changes in version 0.1.0                        

  - Undoing previous DJFMP change and now retaining all DJFMP data
    (except duplicates at the same date and time)
  - Changing EDSM station variable to reflect each unique random 'site'
    so it is possible to identify replicate tows at the same location
  - Tweaked USBR data to retain the average sample time across all
    depths (previously it used the earliest sample time).
  - Tweaked DJFMP data to keep the datapoint closest to noon of each day
    (previously it was averaging across all time points)
  - Added conductivity data from EDSM and DJFMP after 06/01/2019 when it
    was standardized to specific conductivity
  - Added a NEWS.md file to track changes to the package.
