SBC LTER: pH time series: Water-sample pH and CO2 system chemistry, ongoing since 2011

Data are a time-series of pH and carbonate chemistry in
manually-collected sea water samples from nine near-shore locations
along the Santa Barbara Channel, California, USA, and intended to
benchmark data from moored pH instruments. Data collection began in
June 2011 and is ongoing. Time-series for pH sensors deployed in the
field (e.g., SeaFET) are available elsewhere. Discrete seawater samples were collected by hand or using a Niskin
bottle. In the laboratory, samples were analyzed for pH (total scale),
total alkalinity and/or total CO2 (sum of carbon dioxide, bicarbonate
and carbonate). Two parameters were used to calculate the full suite
of carbonate chemistry parameters using the CO2calc algorithms.
Program outputs are included for laboratory conditions as input, and
adjusted for situ temperature. See Methods for more information, e.g.,
Lunden, et al. Data were collected by a consortium of research groups with the intent
to leverage their collective assets and expertise. These groups (and
sponsors) include Santa Barbara Coastal LTER (NSF), OMEGAS Project
(NSF), Passow Lab (Calif. State Water Board), Hofmann Lab (NSF, CINMS,
US NPS).
