Description

This is the starting value for a measurement from an instrument. Another term for it is 'instrument zero'. It is part of the experimental procedure before measuring something as an indication of the error associated with the instrument or the standard concentration solution.

Results from laboratory experiments testing autoinduction in marine diatoms, Thalassiosira pseudonana and Phaeodactylum tricornutum (PhytoplanktonQS project)	Optical Density of the blank at 750 nm. This dataset has three replicate measurements of Optical density blanks: OD_blank1, OD_blank2 and OD_blank3. They correspond to three measurements of the Optical density of the diatom concentration and set the location of the instrument zero.	OD_blank
