Description/Abstract:
CANTON ATOLL HAS A SINGLE PASSAGE BETWEEN THE OCEAN AND LAGOON AND HAS CONSPICUOUS ENVIRONMENTAL GRADIENTS FROM THAT PASSAGE TO THE BACK LAG OON. THESE GRADIENTS INCLUDE THE PHYSIOGRAPHY OF THE LAGOON FLOOR, WAT ER QUALITY, AND THE DIVERSITY AND ABUNDANCE OF CORALS, FISHES, AND MOL LUSKS, THE GRADIENTS CAN APPARENTLY BE ATTRIBUTED EITHER DIRECTLY OR I NDIRECTLY TO CIRCULATION AND WATER MOTION WITHIN THE LAGOON. THOSE OCE ANOGRAPHIC CHARACTERISTICS CAN, IN TURN, BE ATTRIBUTED TO THE GEOLOGIC AL HISTORY OF THE ATOLL, INCLUDING SOME HUMAN MODIFICATION OF THE PASS CONFIGURATION. CONFIGURATION. IN ADDITION TO THE STUDIES OF THE ATOLL LAGOON CHARACT ERISTICS OF THE GROUNDWATER SYSTEM ARE NOTED. EVIDENCE FROM ISOLATED S TANDING WATER BODIES ON THE ATOLL DEMONSTRATES THAT THESE FEATURES SHO W CONSIDERABLE VARIABILITY, WHICH MAY BE ATTRIBUTED TO A COMBINATION O F THE IMMEDIATELY PREVIOUS HISTORY OF THESE BODIES AS WELL AS TO THE P HYSIOGRAPHY OF THE ATOLL.
