This award provides an additional three years of support for the Oceanic Flux Program (OFP). This program was first established in 1978 to measure the export flux of particles from the surface to the deep ocean in the deep Sargasso Sea and represents the longest and most continuous particle flux time-series of its kind. This program and the time-series record will continue to help the oceanographic community to answer questions about the relationship between deep ocean particle flux and climate and biological, physical, and chemical oceanographic processes. In the past, the OFP has provided evidence for coupling between the upper and deep ocean processes linked to seasonal, episodic (e.g., physical and meteorological forcing) and climate patterns. Looking to the future, this program will utilize increasingly advanced instrumentation and analytical tools to address questions about the material that sinks from the surface to deep ocean and its controls. The OFP provides education and training for students from the high school to Ph.D. level and supports early career researchers. The OFP time-series represents a 43-year, nearly continuous record focused on particle fluxes in the deep ocean. With increasingly more data available from the lengthening record, investigators can put observed biogeochemical patterns into perspective to understand the interplay between climate and ocean functioning. The availability of data from complementary nearby Hydrostation S, the Bermuda Atlantic Time-Series (BATS), the Bermuda Testbed Mooring (1994-2007), the Tudor Hill atmospheric tower and other Bermuda sampling programs provide additional opportunities to study upper ocean physics and biogeochemistry coupled with deep ocean biogeochemical processes. The OFP record is becoming long enough to study deep flux linkages with gyre circulation and advective processes. The OFP’s archive is an unparalleled resource for retrospective studies of temporal trends and the biogeochemical consequences of a changing ocean, including future impacts of ocean acidification. As the OFP heads into the future, increasingly sophisticated OFP mooring instrumentation (ADCP current profiling and backscatter; MicroCAT temperature, salinity, and oxygen measurements) and advances in digital imaging and analytical tools (both chemical and genomic) to probe the recovered flux materials continue to reveal novel, fundamental information about the oceanic particle flux and its controls.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项为Oceanic Flux计划（OFP）提供了另外三年的支持。该程序于1978年首次建立，目的是测量粒子从表面到深海深海的出口通量，代表了同类产品中最长，最连续的粒子通量时间序列。该程序和时间序列记录将继续帮助海洋学界回答有关深海粒子通量与攀爬以及生物学，物理和化学海洋学过程之间关系的问题。过去，OFP提供了与季节性，情节性（例如物理和气象强迫）和气候模式相关的上层和深海过程之间耦合的证据。展望未来，该计划将利用日益高级的仪器和分析工具来解决有关从表面到深海及其控制的材料的问题。 OFP为从高中到博士学位的学生提供教育和培训。水平并支持早期职业研究人员。 OFP时间序列代表了43年，几乎连续的记录，重点是深海的粒子通量。随着越来越多的延长记录可用的数据，研究人员可以将观察到的生物地球化学模式置于观点，以了解气候与海洋功能之间的相互作用。从Hydrostration S，Bermuda Atlantic Time系列（BAT），Bermuda Testbed Mooring（1994-2007），Tudor Hill大气塔和其他Bermuda抽样计划提供的数据提供了其他机会，可为研究上海洋物理学和深层海洋生物化学的研究提供其他机会，从而提供了其他机会。 OFP记录已经变得足够长，可以研究与回旋循环和高级过程的深层磁通链接。 OFP的档案是对临时趋势和不断变化的海洋生物地球化学后果的回顾性研究的无与伦比的资源，包括海洋酸化的未来影响。随着OFP进入未来，越来越复杂的OFP系泊仪器（ADCP电流分析和反向散射；微电脑温度，盐度和氧气测量值）以及数字成像和分析工具的进步（化学和基因组）（化学和基因组），以探测恢复的通量材料继续揭示了有关海洋颗粒的新颖信息，并揭示了有关海洋粒子的新信息。通过使用基金会的知识分子和更广泛影响的评论标准来通过评估来支持。
