BIOPHYSICAL INTERACTIONS
-
Atmosphere
Storm waves rip apart soft corals, hard corals are chipped/damaged
-
-
Cyclone Larry removed layers of accumulated sediment and reduced water temperature - saving reef from major bleaching
-
-
Lithosphere
-
-
-
Corals dies, limestone allows for new coral growth
Sediments produce turbidity & reduce amount of penetrating light, interrupting photosynthesis process
-
Hydrosphere
-
-
-
Warm, high saline waters that flow down bring relatively high nutrient levels
-
-
Biosphere
Large numbers of coral, jellyfish, molluscs & crustaceans
-
-
-

-
SPATIAL PATTERNS
-
-
Continuity
Todays reef has existed for 10,000 years
-
-
NATURE & RATE OF CHANGE
Natural Impacts
Tropical cyclones damage coral & bring fresh water onto reef -> alters salinity -> stress on corals/fish
