Research Abstract |
2010 A.D.: Lists of living hermatypic corals weremade by sketches and underwater photographs along coasts of Otsuki To wn, Kochi Prefecture and Ishigaki-jima, Okinawa Prefecture. Temperate and subtropical communities were proposed by a statistical method. 2011 A.D.: Coral communities were observed by the same methods along coa sts of Otsuki Town and Amami-oshima, Kagoshima Prefecture. Sea water s amples were collected at the same localities to measure chemical compone nts, such as pH, Total Carbon, and Total Alkalinity. Organic and inorgani c carbon productions were calculated by photo-quantum sensor. 2012 A.D.: Densities of the living coral patches were reconstructed on th e aerial photographs taken at the same localities. Although no clusters o f hermatypic corals cannot be seen in the temperate, dense coral patches are abundant in the sub-tropics. Plots of the coral density and latitude are linear.
