Bottom Tethered Sediment Trap Array Experiment, GOFS Level 1

GOFS 将进行底部系留时间序列沉积物捕获实验以及初步实验室和分析计划，其中包含有关北大西洋内部沿西经 20 度的粒子通量的质量和数量的连贯信息。 将使用3个固定陷阱深度形成同步时空矩阵：1000 m。深度 2000 m，距地面 700 m，在两个 GOFS 20 度西站：大约北纬 33 度和北纬 47 度。单位采样周期为 2 周，实验将不间断地持续至少 2 年。 这些杯子预先用缓冲甲醛防腐剂中毒，并且除了收集阶段外，在整个部署期间都与周围海水完全密封。 拟议的 GOFS 阵列矩阵将使用 SYNCTISE 系泊部署技术进行部署，并将在每年两次为期 3 周的运输期间进行维护，优先用于中型/大型研究船上的阵列部署。 拟议的实验将每年收集 144 个单位样本，构成来自北大西洋西经 20 度横断面的 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.
