Total alkalinity, pH, dissolved oxygen, and other variables collected from time series observations using alkalinity titrator, pH electrode, oxygen optode and other instruments in a shallow back reef on Ofu, American Samoa from 2011-11-12 to 2012-03-27 (NCEI Accession 0127952)

This dataset consists of time series of physical and biogeochemical data from 8 locations (8 tubes) in Pool 100 as well as temperature time series from Pool 300, an adjacent back reef Pool. The 8 tubes are polypropylene tubes that are strung out onto the reef in order to pump water to beachside instrumentation. Therefore, sampling from the tubes defines the edges of a 3-dimensional sampling box 14 m in width by 40 m in length from which water was sampled from all 8 edges continuously for ~1 week. Later, we collected temperature data from Pool 300 as described above. The phrase "Pool" is another term for back reef environment that is used commonly when referring to Ofu's coral reefs (hence the use of the phrase Pool in the paper and in its accompanying data set). There are three data files associated with this archival package. All data files are in MATLAB format.

Long-term temperature time series from Pool 300 back reef and offshore (data in Fig. 3e of the paper) 3. Biogeochemical data from Pool 100 (data in Figs. 4-6 of the paper).
