Abstract:

These data were published in (Comeau et al. 2017).

Expand/Collapse All

Methods & Sampling

Confocal pH measurements were made using ratiometric analysis of two forms of the dual emission pH-sensitive dye SNARF-1 (Invitrogen) according to methods published previously (Venn et al. 2011; 2015).

See Comeau et al. (2017) for a detailed overview of the methodology.

BCO-DMO Data Manager Processing Notes:
* Data submitted as sheet "Snarf pH" in original excel file "comeau et al. 2017_proceedings_data.xlsx" exported as csv with the formatting that was set in Excel.
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions: only A-Za-z0-9 and underscore allowed. Can not start with a number. (spaces, +, and - changed to underscores).

Supplied Description:

Confocal pH: pH-sensitive dye SNARF-1. Photographed with Leica SP5, Germany. See methods in Venn et al. 2011.

Instrument Type

Generic Name: pH Sensor

Generic Description:

An instrument that measures the hydrogen ion activity in solutions.

The overall concentration of hydrogen ions is inversely related to its pH. The pH scale ranges from 0 to 14 and indicates whether acidic (more H+) or basic (less H+).
