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
