EFFECTS OF CHEMICALLY DISPERSED OIL ON THE BRAIN CORAL, DIPLORIA-STRIGOSA Academic Article uri icon

abstract

  • The frequency of oil spills in tropical seas may threaten coral reef survival and some of the past research has indicated that oil alone as well as oil dispersed with chemical dispersants is toxic to corals. These experiments were probably realistic of intertidal reef zones and sheltered shallow reef areas. However, few experiments have incorporated analytical chemistry necessary to relate reported biological effects to actual oil spill concentrations and exposure times. This paper outlines some new results with emphasis on a 3 year programme carried out in Bermuda using a flow-through laboratory dosing system, comparative laboratory and field experiments, real time measurements of oil concentrations, and non-destructive bioassays to allow repetitive data collection from the same specimens. Suggestions for future research programmes are given in light of these results. In addition to research on the effects of oil and chemically dispersed oil on other coral species and associated organisms in the coral reef, the relative sensitivity of the various ecosystems comprising the tropical coastal zone (mangroves, seagrasses and reef) must also be addressed. It is hoped that such advances will ensure that overall oil spill clean-up decisions will give due consideration to the individual physical and biological characteristics of each of these tropical environments. 1987.
