Note
In the past two years since the opening of the Laboratory, a number of projects have been undertaken involving the submersihle "Johnson-Sea-Link". (A film of a portion of the hyperbaric studies at Duke University, undertaken by the Harbor Branch Foundation, will be shown at the close of the paper). The author's own research activities are related to an"assessment of the role of sabellariids, reef building marine organisms, in the nearshore waters along the lower East Florida Coast.
