What's Down There? Ocean Topography at the Ventura Pier

CSEF · 2005 Earth Sciences/ Planetary Sciences/ Physical Environments

Allyson Drinkert, Ellen George, Michael Kreider · Foothill Technology High School, Ventura

Overview

Objectives/Goals The bottom composition of the ocean varies greatly around the world. This experiment tests the effect of depth on bottom composition at the Ventura Pier. It is hypothesized that as depth increases, the material found will become coarser and/or larger. Methods/Materials This experiment used a can and weight, fishing line, Tanglefoot wax, plastic bags, and colored electrical tape. First the height of the pier was found by lowering the weight in the can down to the ocean#s surface, and then the total height of the ocean depth and the pier height were tested at eleven evenly spaced intervals along the pier. The material on the bottom at each particular measuring site was collected by spreading Tanglefoot wax on the bottom of the can, which was covered in a plastic bag. Conclusions/Discussion After graphing, it was found that the hypothesis was correct, for as the depth increased, the bottom composition became coarser and larger.

Summary statement

Our project investigates the change in bottom composition as ocean depth increases along the Ventura Pier.

Help received

Our advisor reviewed our completed project, however, the entirety of the project was executed and completed by the student members.
