Note(s): The development of research submersibles has allowedscientists of various disciplines to ask new questions and readdressold ones about the world's oceans. The Johnson Sea-Linksubmersibles are being used to discover and study deep-waterbenthic macroalgal communities in Florida and the Bahamas. Whiletheir full extent is not yet known, communities of richly diverseand abundant algae have been found in areas of suitable substrateand favorable water quality. Zonation patterns are evident inthese communities. In all cases, the deepest (to ca. 270 m)plants are crustose red algae. Fleshy algae, in particularcertain green algae, can be found in depths as great as ca. 200m. The few measurements of productivity that have been made onthese plants are higher than previously expected and indicatethat the contribution of deep-water benthic macroalgae should beincluded in global estimates of primary production. The degreeto which these plants are grazed by herbivores is unknown.Physiological studies on these algae may elucidate new mechanismsfor adaptation to their deep-water environment. Althoughresearch on these organisms is in its infancy, it is clear that astudy of the biology of deep-water macroalgae will be richlyrewarding.
