Time Series Particle Flux Measurements in the Sargasso Sea

9711703对当今海洋/气候相互作用的理解主要基于作为长期研究工作的一部分收集的时间序列数据。长期研究对我们了解海洋如何运作的贡献是巨大而深远的。然而，这样的研究是极其罕见的，尤其是那些以生物地球化学为重点的研究。OFP时间序列现已接近其第20个年头。这是为数不多的跨越十年以上的海洋记录之一，也是迄今为止同类记录中最长的时间序列。OFP时间序列提供了无与伦比的深海物质通量长期变化记录，以及粒子通量与上层海洋过程之间密切联系的直接证据。OFP记录仍然是生态系统功能和“生物泵”效率的时间变化的主要证据之一。OFP时间序列现在变得足够长，可以开始确定似乎与北大西洋气候系统变化直接相关的物质通量的大小和组成的重要长期趋势。该项目继续与大量研究人员共享其资源-以样品材料，数据，辅助船舶时间和系泊平台的使用的形式-使各种详细的，一般面向过程的调查成为可能，这些调查极大地扩展了该计划的科学成果。综合这些数据集将导致在确定上层海洋对流入海底的物质通量的数量和组成的控制方面取得重大和根本性的进展。这些发现对于了解和预测海洋对未来（可能是人为引起的）气候变化的反应以及开发全球碳通量模型至关重要。

9711703 Conte Understanding of present-day ocean/climate interactions based largely upon time-series data collected as part of long- term research efforts. The contributions of long-term studies to our knowledge of how the ocean works are numerous and far- reaching. Yet, such studies are exceedingly rare-especially those with a biogeochemical focus. The OFP time-series is now approaching its 20th year. It is one of the very few oceanographic records spanning more than a decade and, by far, the longest time-series of its kind. The OFP time-series has provided an unparalleled record of secular changes in material fluxes to the deep ocean, and direct evidence of the close linkages between particle fluxes and upper ocean processes. The OFP record remains on e of the main pieces of evidence for temporal variability in ecosystem functioning and in the efficiency of the "biological pump". The OFP time-series is now becoming long enough to begin to identify significant long-term trends in both the magnitude and composition of the material flux which appear to be directly linked to variation in the North Atlantic climate system. The project continues to share its resources- in the form of sample material, data, ancillary shiptime, and use of the mooring platform- with a large number of researchers to make possible a diverse range of detailed, generally process-oriented investigations which have greatly expanded the scientific results of the program. Synthesis of these datasets will lead to major and fundamental advances in identifying the upper ocean controls on the quantity and composition of material flux to the seafloor. The findings will be of paramount importance for understanding and predicting the ocean's response to future, possibly anthropogenically induced, climatic change and for development of global carbon flux models.
