The Hawaii Ocean Time-Series Program: JGOFS Component

9301368 Karl该项目提供了一个深水、开放的海洋水站，作为观察和解释海洋物理和生物地球化学变化的寡营养海洋基准。大约每隔一个月对一套核心参数进行重复实地测量，并将数据汇编并分发给科学界。目前的项目包括对正在进行的测量进行改进，例如增加了连续的氢剖面，延长了选定的HOTS巡航，继续使用沉积物捕集器系泊，增加了低水平铵测定的测量，以及使用新技术测量细菌产量。与此同时获得的相关资助包括用于颜料测量的Bidigare （OCE- 9315311）和用于无机二氧化碳测量的Winn （OCE 9315312）。关于HOTS的持续工作将有助于了解少营养化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.
