The Hawaii Ocean Time-Series Program: JGOFS Component

小行星9301368 该项目提供了一个深水、开阔海洋水文站，作为观测和解释海洋物理和生物地球化学变化的贫营养海洋基准。大约每月一次对一套岩心参数进行重复现场测量，并汇编数据和分发给科学界。目前的项目包括不断改进正在进行的测量，如增加连续水文剖面测量，延长选定的HOTS巡航，继续沉积物捕集系泊，增加低水平铵测定测量，以及 使用新技术测量细菌产量。 与此同时获得的相关赠款包括用于颜料测量的Bidigare（OCE- 9315311）和用于无机CO2的Winn（OCE 9315312）。 继续开展HOTS的工作将有助于了解贫营养海洋在全球碳循环中的作用，并有助于解决对该循环至关重要的过程的变化的时间尺度。

9301368 Karl This project provides a deep-water, open ocean hydrostation as the oligotrophic ocean benchmark for observing and interpreting physical and biogeochemical oceanic variability. Repeat field measurements of a suite of core parameters are made on approximately monthly intervals, as well as compilation of the data and distribution to the scientific community. The current project includes ongoing improvements to the measurements being made such as the addition of a continuous hydroprofiling, extension of selected HOTS cruises, continuation of the sediment trap mooring and added measurements of low-level ammonium determinations, and bacterial production measurements using a new techniuque. Related grants awarded simultaneously with this one include Bidigare (OCE- 9315311) for pigment measurements, and Winn (OCE 9315312) for inorganic CO2. Continued work on HOTS will contribute to understanding of the role of the oligotrophic ocean in the global carbon cycle and to resolving the time scale of variations in processes important to that cycle.
