Hy tom, 
this is marcos Gektidis from Frankfurt , Germany.=20 
The report probably dealt with the ENCORE - project on One Tree Island,=20 
Australia. I' m currently involved in that project. Several Microatolls=20 
on One Tree Reef are "poisoned" with an elevated nutrient level. There=20 
are N-, P-, and N plus P- injektions. The ENCORE-programm runs already=20 
since 1994 but the elevated nutrient - doses proved too small. This will=20 
be changed next year. For more information, please contact me:
