We describe in detail the pore water chemistry in the sediments below a white mat around a bunch of bananas at a water depth of 2,200 m in the Tenryu Submarine Canyon. We infer the metabolism of microbes in the sediments around the bananas based on the chemical and isotopic compositions of the pore water. On the basis of the relation between ammonia and total carbonate (ΣCO2) concentrations in the pore water, we identified that an excess ΣCO2 was distributed around the bananas that cannot be explained by the decomposition of organic matter derived from marine organisms, indicating that the bananas decomposed to generate the excess ΣCO2. We conclude that the bananas built a local organic-rich environment, stimulating the activity of organotrophic bacteria.

[琉球大学] 土岐先生。この間、光森さんが教えてくれたのはこれか。海底に落ちていたバナナの周辺環境におよぼした化学的な影響みたいな理解でいいのかな。
