Aided by an army of beachcombers, oceanographer Dr. Curtis Ebbesmeyer tracks trash in the name of science. From sneakers to hockey gloves, Curt monitors the watery fate of human-made cargo that has spilled into the ocean. The information he collects is much more than casual news; it is important scientific data. And with careful analysis, Curt, along with a community of scientists, friends, and beachcombers alike, is using his data to understand and protect our ocean.

In engaging text and unforgettable images, readers meet the woman who started it all (Curt's mother!), the computer program that makes sense of his data (nicknamed OSCURS), and several scientists, both on land and on the sea, who are using Curt's discoveries to preserve delicate marine habitats and protect the creatures who live in them.
