algae disappeared at a faster rate. At water temperatures exceeding 

 25 C, the relative percentages of reds, browns, and greens were 

 50:12:38; at 30°C and above, the ratios were 57:5:38.

 to the thermal discharge than any other station, and has had the lowest 

 ratio of browns to greens for the past three years. Twotree Island is
