Abstract:

Behavioral effects were documented during acute static exposure experiments of various larval stages of eastern oyster, Crassostrea virginica (D stage, eyed), and phytoplankton food sources: algae (Isochrysis galbana-Tahitian strain).

Purpose:

The specific intentions of this dataset are: 1. To document the behavioral effects that occurred on various life stages of oysters during acute exposure to oil and Corexit, 2. To document the behavioral effects (motility) of phytoplankton (algae species) that occurred while conducting acute static toxicity exposure experiments to oil and Corexit
