Mesocosm Tanks at RTC with Seagrass (image) San Francisco State University Caption This shows Mesocosm tanks at RTC with seagrass raised for experiments on genetic diversity in restoration using seed buoys.These are offspring from the Crown Beach site that grew from seeds dropped from seed buoys in the tank. The seeds germinated in the tanks and grew eventually into large plants visible in this photo. Samples for genotyping were collected while plants were small and could be distinguished from each other. Tanks located at the RTC lab in an outdoor greenhouse are supplied by water pumped from the bay. Credit Photo by Brian Ort.
