Amphipod Reburrowing Time
in Response to Sediment Pollution

The following data are a subset from an experiment by Dr. Linda Schaffner and Bruce Vogt at the Virginia Institute of Marine Science. All amphipods were collected from Queen's Creek, a tributary of the Chesapeake Bay in Virginia. The goal of the experiment was to determine whether or not sediment contamination has an effect on the reburrowing time of amphipods.

Four groups of 10 amphipods were placed in different sediment types and their reburrowing times were measured in seconds. The experimental procedure was as follows.

For example, the first amphipod in the first column was transferred from clean sediment to another container of clean sediment, and took 7 seconds to reburrow. (Click here for a more detailed explanation of the experimental method.)
