SBC LTER: Ocean: Time-series: Mid-water SeaFET pH and CO2 system chemistry with surface and bottom Dissolved Oxygen at Mohawk Reef(MKO), 2012 - 2017

Calibrated pH (Total scale, SeaFET sensor) an disoolved oxygen (miniDOT)data were
collected from Mohawk Reef in the Santa Barbara Channel (site ID: MKO). pH data are
accompanied by in situ temperature and associated carbonate chemistry parameters. The SeaFET
instrument is located about 4 meters from the surface, with other moored instruments.
Associated carbonate chemistry parameters were calculated with the CO2calc programs from
USGS, and include: partial pressure and fugosity of CO2, concentrations of bicarbonate,
carbonate and hyrdroxide ion, Omega (saturation state) of calcite and aragonite. Dissolved
oxygen sensors (miniDOT, PME) were added in 2014, and are mounted near the ocean surface and
near the seafloor, and also report temperature. All data have been interpolated to a 20
minute time interval for compatibility with other SBC LTER moored instrument data. Data
coverage is 2012-01-11 to 2017-12-19.The update of this
dataset was terminated in 2019. All data from this site have been concatenated with the pH data from
the other sites and merged into one data package:
