Organic Geochemical Flux Studies in the Equatorial Pacific Using Swimmer-Excluding Rotator Traps

私家侦探：建议进行有机地球化学 中环空气中微粒物质通量的调查 赤道太平洋（EQPAC）。 这项研究应该让他们 调和水柱生产和下沉通量的 主要生化物质（脂质、氨基酸、色素和 碳水化合物）与相应的沉积物递送， 积累和保存率，使用远远超过100 单独的有机化合物。 主要问题是：1）什么 是赤道太平洋表面的粒子动力学 反映在它们的有机成分上 2)什么分数 在地表沃茨中产生的不同生化物质 到达深海，并在沉积物-水中积聚 接口？ 3)什么是不同的相对反应性 底层沉积物中的有机物 4)做 生物化学分布与无机物略有不同， 研究沿着各种沉积物类型的组成 样带？ 为了解决这些问题，PI：s将采样 悬浮颗粒通过原位泵送，沉降颗粒使用 我们新的游泳者排除陷阱，和底部沉积物从框 协调样带和时间序列台站的核心 与其他EQPAC调查员一起采样。

The P.I.:s propose to conduct an organic geochemical investigation of the flux of particulate matter in the Central Equatorial Pacific (EQPAC). This study should allow them to reconcile water column production and sinking fluxes of the major biochemicals (lipids, amino acids, pigments, and carbohydrates) with the corresponding sediment deliver, accumulation and preservation rates, using well over 100 individual organic compounds. Major questions are: 1) What are the dynamics of particles in the surface Equatorial Pacific as reflected by their organic constituents? 2) What fractions of the different biochemicals produced in the surface waters reach the deep ocean and are accumulated at the sediment-water interface? 3) What are the relative reactivities of different organic substances in the underlying sediments? 4) Do biochemical distributions differ appreciably with the inorganic composition of the various sediment types along the study transect? To address these questions the P.I.:s will sample suspended particles by insitu pumping, sinking particles using our new swimmer-exclusion traps, and bottom sediments from box cores at transect and time-series stations in coordination sampling with other EQPAC investigators.
