Water Temperature and Cyclone Frequency in the Pacific: Implications for Pearl Farming Final, June 2008FIGURESFigure 1. Mean monthly sea surface temperatures derived from the hourly data collected byoceanographic monitoring buoys deployed in Manihiki and Penrhyn Lagoons, NorthernCook Islands.Figure 2. Mean monthly coastal ocean temperatures recorded by probes deployed at (a)silver-lip pearl oyster farms in Roebuck Bay and Exmouth Gulf and (b) at Barrow Island,Osprey Bay and Shark Bay, Western Australia.Figure 3. Mean monthly sea surface temperature records from weather stations atAgincourt, Davies, Hardy and Myrmidon reefs on the Great Barrier Reef, north-east coast ofAustralia.Figure 4. Variation in sea temperature records from an in-situ logger deployed at a depth of5-7m on Mount Mutiny, Vatu-i-Ra, Fiji for the period January 1997 to November 2007.Figure 5. Comparison of sea temperatures recorded by in-situ loggers deployed at YasawaIsland, Vatu-i-Ra, Kadavu and Suva Harbour over the period September 2006 to October2007.Figure 6.
