    • Abundance and Size Distribution of Particulate Matter Fractions Near a Caribbean Bank Barrier Reef 

      Simmons, George M., Jr. (Inter-Research, 1979)
      Recent research indicates that corals have the ability to occupy several trophic levels and that particulate matter (PM) appears to play a major role in meeting their daily energy requirements. A study was undertaken to ...
