Description

This dataset includes cell volume measurements from Rhodomonas grown at varying pCO2 levels, and fed to copepods, from 2015.

Methods & Sampling

Dataset acquisition description

The phytoplankton Rhodomonas sp. CCMP 755 was grown semi-continuously in atmosphere controlled chambers at three different CO2 treatment concentrations; Ambient (400ppmv), Moderate (800ppmv), and High (1000ppmv). Cultures were diluted daily starting day 4 with pre-equilibrated media containing f/50 nutrients. Cells were counted live using a Z2 Coulter Particle Counter and cell volumes were recorded for the first five cells counted from each treatment each day.

Data Processing Description

Dataset Processing Description

The data are unprocessed.

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions

Instruments

Coulter Counter

Supplied Name: Z2 Coulter Particle Counter

Supplied Description:

Used to count cell culture samples

Instrument Type

Generic Name: Coulter Counter

Generic Description:

An apparatus for counting and sizing particles suspended in electrolytes. It is used for cells, bacteria, prokaryotic cells and virus particles. A typical Coulter counter has one or more microchannels that separate two chambers containing electrolyte solutions.
