| Research Abstract |
The aim of this study is to assess the impact of global warming by an index of seaweed flora and bed at Omaezaki, Suruga Bay. The number of species in green algae those currently growing at Omaezaki were increased from 21 to 27, whereas brown algae decreased from 39 to 24. During 76 years (1935-2010) at Omaezaki, the annual average temperatures were increased 0.89 degrees centigrade in air and 0.52 degrees centigrade in water. Moreover, the biomass of seaweeds was haigh in lowere annual average air and water tenperatures, and low in higher temperatures. Thus, seaweed flora and bed was judged to be able to be an index of the impact assessment of global warming.
