Spatial Variation of CO^-_2 and SO^-_3 Radicals in Massive Coral as Environmental Indicator
スポンサーリンク
概要
- 論文の詳細を見る
Electron spin resonance (E,SR) signal intensities of a massive coral colony from the Great Barrier Reef are measured-along the growth direction with a microwave scanning ESR imaging system. The annual high intensity regions of CO^-_2 radicals are the same as the skeletal high density regions. Those of SO^-_3 radicals are the same as the yellow-green fluorescent bands which correlate with summer. A long-range fluctuation which has a 12-year cycle is also observed in the intensities of these two radicals. Thus, the E,SR signal intensities of coral can be used as an indicator of past environmental changes.
