Title: Effect of Gasoline on Coral Bleaching


1
Effect of Gasoline on Coral Bleaching
  • Group 4
  • Joon Chung
  • Jimmy Wesman
  • Nauman Chandry
  • Heather Hollembeak
  • Sebastian Camacho
  • Will Quartell

2
Question
  • How does gasoline concentration affect the
    symbiosis between the polyps and zooxanthellae?
  • At what levels of gasoline concentration will
    polyps bleach?

3
Hypothesis
  • Due to 87 Octane acting as an anthropogenic
    factor, zooxanthallae will die off and coral
    bleaching will occur.
  • This will result in withering and ultimately,
    death.

4
Why Gasoline?
  • Outside stressors, such as gasoline spill, cause
    zooxanthallae to fall off by hindering the light
    from reaching it.
  • Oil seepage may poison the coral.

5
Our Variable
  • 87 Octane
  • This is the closest variable we could get to
    regular gasoline oil.
  • Week 1- 0.64 ml of gasoline in a tank
  • According to Canadian Environmental Assessment
    Agency, standard is 80 micrograms per gram of
    water in Canada. This converts to 0.64 ml / tank
    (80L).
  • Week 2- 1.28 ml
  • We will increase the amount of gasoline by 0.64.

6
Procedures
  • Regular Grade (87 octane) gasoline will be poured
    at a specific concentration, 0.64 ml, every week.
  • zooxanthallae counts, chlorophyll concentrations,
    and protein concentration will be recorded every
    week.
  • Analyze Results
  • Draw conclusions based on growth/death rates of
    Coral in tank
