Stillwater Cove is one of the best studied kelp beds in the world. Moss Landing Marine Lab’s very own Mike Fox is studying giant kelp growth in Stillwater. The R/V John Martin took a group out to tag giant kelp in order to more easily locate them when they go reproductive. Large blades called sporophylls cover the holdfast and make it difficult to see the tags, so we attached white lines to a nearby winged kelp algae.
