Release of Particulate and Dissolved Organic Carbon by the Scleractinian Coral Acropora Formosa
Abstract:Measurements of both particulate and dissolved organic carbon (POC and DOC) release by corals are important in understanding the organic carbon cycle in reef systems. In this study, branches of Acropora formosa (Dana, 1846) were incubated for 5 hrs and the release of POC and DOC into the ambient water was simultaneously measured. POC release rate (average ± SD) was 8.93 ± 1.67 mg C m–2 hr–1 while DOC release rate was 14.98 ± 4.26 mg C m–2 hr–1. Consequently, the majority (ca. 63%) of organic carbon released by A. formosa dissolves into the seawater.
