Bottom Tethered Sediment Trap Array Experiment Equator to 12Degrees South, 140 Degrees West

作为JGOFS赤道太平洋实验项目（EquiPac）的核心任务要素，伍兹霍尔海洋研究所（WHOI）和俄勒冈州立大学（OSU）将共同努力，部署沉积物陷阱矩阵，以了解赤道太平洋内部沿140°/ 1350°W的粒子通量在时间和空间上的变化，并向所有EquiPac实验室提供关键样品。的 私家侦探我们建议在赤道上的7个EquiPac站形成一个从北纬90度到南纬120度的精确同步矩阵，这些站位于三个陷阱深度：1200米、2200米和700米以上；将在赤道阵列上增加一个800米的陷阱，总共22个陷阱，每个0.5平方米，在5个JGOFS站，从赤道到南纬120度，跨度为12度，1,333公里。单位采样周期为两周（14天），与JGOFS N.A. Bloom实验相同。样品用缓冲甲醛防腐剂预先中毒，除收集阶段外，在整个部署期间与周围海水积极密封。WHOI将负责4个阵列，其中13个陷阱将部署在赤道以南的0点，20点，50点和120点，OSU将负责其余的北部阵列。世卫组织和俄勒冈州立大学的实验室将合作尽早向联合地表观测系统提供下列基本成分的数据：总（干）通量、碳酸盐通量、可燃通量、生物硅酸盐通量和岩性通量、可燃有机质中的碳、氮含量，以及取样器杯中固体和溶解相中的有机/无机磷含量，使用3个1/10等分。世卫组织和俄勒冈州立大学将完成分析程序的相互校准，并在密切的实验室合作下产生一致的数据。1/10的等价物将在每个实验室存档。其余的通量样品的6/10，平均每单位样品约300毫克，允许根据站点和季节有很大的差异，将分配给相关的JGOFS方案。//

As a core-task element of the JGOFS Equatorial Pacific Experiment Programs (EquiPac), Woods Hole Oceanographic Institution (WHOI) and Oregon State University (OSU) will combine efforts to deploy a matrix of sediment traps to understand the variability of particle fluxes in time and space in the interior of the Equatorial Pacific along 140o/135o W and provide critical samples to all EquiPac laboratories. The P.I.'s propose to form a precisely synchronized matrix from 9o N to 12o S through the equator at 7 EquiPac Stations at three trap depths: 1,200 m, 2,200 m in depth, and 700 m above the floor; an 800 m trap will be added to the array at the equator, totaling 22 traps, 0.5 m2 opening each, at five JGOFS stations, from the equator to 12o S with a span of 12 degrees, 1,333 km. A unit sampling period will be two weeks (14 days), the same as the JGOFS N.A. Bloom Experiment. Samples are pre-poisoned with buffered formaldehyde preservative and, except for during the collection phase, are positively sealed from ambient sea water throughout the period of deployment. WHOI will be in charge of 4 arrays with 13 traps to be deployed south of the equator at 0o, 2o S, 5o S and 12o S, and OSU will take care of the remaining northern arrays. WHOI and OSU laboratories will collaborate to provide JGOFS with data on the following essential components at the earliest opportunity: total (dry), carbonate, combustible, biogenic silicate, and lithogenic fluxes, carbon, nitrogen contents in combustible organic matter, and organic/inorganic phosphorus in solid and dissolved phase in the sampler cup using three 1/10 aliquots. WHOI and OSU will complete intercalibration of the analytical procedure and produce coherent data under close laboratory collaboration. A 1/10 aliquot will be archived at each of the laboratories. The rest, 6/10 of the flux sample, an average of approximately 300 mg per unit sample allowing a large margin of differences according to station and season, will be distributed among the relevant JGOFS programs. //
