Abstract:

The dataset contains the results of grazing and incubation experiments of marine unicellular grazers in exposure to the water accommodated fraction (WAF) of crude oil and chemical dispersant at various concentrations. The data were generated based on laboratory experiments conducted at Buskey’s lab at the Marine Science Institute of University of Texas at Austin. The data were collected intermittently from Mar 2017 through December 2019. The data include the cell dimension measurements of microorganisms used for the experiments, the growth rates of different micro-sized grazer and algal prey species, the median growth inhibition concentration of the growth rates of protistan species, the grazing rates of protozoan grazers and the gross growth efficiencies of grazer species. The dataset also includes the estimated initial concentrations of total polycyclic aromatic hydrocarbons (PAHs) and individual PAH of the test media used for the exposure experiments.

Purpose:

To investigate the sub-lethal effects of the water accommodated fraction of crude oil and chemical dispersant exposure to the growth and grazing responses of marine unicellular grazers.

Data Parameters and Units:

Cell dimension (um), Cell volume (um^3), concentration of PAHs (ug/L), cell density (cells/mL), specific growth rate (/day), prey density ratio (no unit), median growth inhibition concentration (ug/L), specific grazing rate (cells/grazer/day), and gross growth efficiency (no unit).

Methods:

The methods include laboratory manipulation of cultures, preparation of test media with crude oil and (or) chemical dispersant, incubation experiments in incubators, enumeration of cells under the microscope, and statistical analysis of results.
