| n April of 1996, the Pearson College Environmental Systems Class planned a field lab which would enable us to present a profile of the currents around the Race Rocks Ecological Reserve. |

Symbala lifts a drogue into the boat. We obtained these drogues as surplus from the Alaskan Oil Spill.
|
The drogues were released on an ebb tide between North Race Rock and Great Race Rock. Here the class has a drogue drifting in the background. |
We also take time out to study the behavior of the sea lions hauled out on the islands of the Ecological Reserve at Race Rocks |
 |
We have fitted the drogues with radar reflectors so that we can determine the distances from the islands in our plotting process. |
The drogues were released on an ebb tide between North Race Rock and Great Race Rock. The students were able to map the current direction through the islands using the radar on the boat docked at the jetty
