Bottom Tethered Sediment Trap Array Experiment, GOFS Level 1

将对GOFS进行海底系泊时间序列泥沙捕集实验和初步实验室和分析程序，以获得关于北大西洋内部沿20°W子午线的粒子通量的质量和数量信息。在北纬33度和北纬47度的两个GOFS 20度站，将使用3个固定的圈闭深度形成同步的时空矩阵：深度1000米。深度2000米，离地面700米。单位采样周期为2周，实验将不间断地持续至少2年。杯子用缓冲的甲醛防腐剂预先下毒，除了在收集阶段外，在整个部署期间都与周围的海水紧密密封。拟议的GOFS阵列矩阵将使用SYNCTISE系泊部署技术进行部署，每年在一艘中型/大型考察船上进行两次为期3周的装运时间维护，按阵列部署的优先顺序排列。这项拟议的实验将导致每年收集144个单元样本，组成北大西洋20度西样带的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.
