Bottom Tethered Sediment Trap Array Experiment, GOFS Level 1

将对GOFS进行海底系留时间序列沉积物捕集器实验和初步实验室和分析方案，并提供有关北大西洋内部沿西经20度的颗粒通量的质量和数量的连贯信息。在两个GOFS西经20度站（约北纬33度和北纬47度），分别设置1000米、2000米和700米的固定陷阱深度，形成同步的时空矩阵。单位采样周期为2周，实验将不间断持续至少2年。杯子预先用缓冲甲醛防腐剂中毒，除了在收集阶段，在整个部署期间都与周围的海水积极密封。拟议的GOFS阵列矩阵将使用SYNCTISE系泊部署技术进行部署，并将在每年两周的船舶时间内进行维护，优先用于阵列部署，用于中型/大型研究船上。拟议的实验将导致每年从北大西洋20度W样带收集144个单位样本，构成GOFS时空矩阵。

A bottom-tethered time-series sediment trap experiment and preliminary laboratory and analysis program will be conducted to GOFS with a coherent body of information on the quality and quantity particle fluxes in the interior of the North Atlantic along the 20 degree W meridian. A synchronized time-space matrix will be formed using 3 fixed trap depths: 1000 m. 2000 m in depth, and 700 m above the floor, at two GOFS 20 degrees W stations: at approximately 33 degrees N, and 47 degrees N. A unit sampling periods will be 2 weeks and the experiment will be continued without interruption for at least 2 years. The cups are pre-poisoned with buffered formaldehyde preservative and, except for during the collection phrase, are positively sealed from ambient sea water throughout the period of deployment. The proposed GOFS array matrix will be deployed using SYNCTISE mooring deployment techniques and will be maintained during two 3-week periods of shiptime, prioritized for array deployment, on a medium/large-sized research vessel each year. The proposed experiment will result in the collection of 144 unit samples each year making up the GOFS time-space matrix from the North Atlantic 20 degree W transect.
