Abstract
Disadvantages of the Olson drift card are discussed, and a newly designed polythene drift card (3 mm thick) is described. This card is compact and complete. In tests along the South African coast it has proved to be durable and convenient. The tests indicate that it compares favorably with either drift bottles or the Olson plastic envelopes.
