Organic compounds in sediments and pore waters of ODP Sites 117-723 and 117-724@en

Total organic carbon, amino compounds, and carbohydrates were measured in pore waters and sediments of Pliocene to Pleistocene age from Sites 723 and 724 (ODP Leg 117) to evaluate (1) relationships between organic matter in the sediment and in the pore water, (2) the imprint of lithological variations on the abundance and contribution of organic substances, (3) degradation of amino compounds and carbohydrates with time and/or depth, and (4) the dependence of the ammonia concentration in the pore water on the degradation of amino compounds in the sediment. […]本研究对大洋钻探计划（Ocean Drilling Program, ODP）第117航次723、724站位的上新世至更新世时期的孔隙水与沉积物样品，开展了总有机碳（Total organic carbon）、氨基化合物及碳水化合物的含量测定，旨在评估以下四项内容：（1）沉积物与孔隙水中有机质的相互关系；（2）岩性变化对有机质丰度及其组分贡献的影响印记；（3）氨基化合物与碳水化合物随时间和/或深度的降解规律；（4）孔隙水中氨浓度与沉积物内氨基化合物降解过程的依存关系。[…]
