Environmental Variability in the Central North Pacific Near Hawaii

北太平洋环流的数据将被检查，以确定 环流的正常变化程度，以及 夏威夷周围地区是典型的环流。 初步 对历史数据的分析表明， 夏威夷附近的上层海洋， 在长横断面上观察到的结构和多年来的高潮 站，大约750公里以北的夏威夷。 目前还不知道是否 这些暂时确定的差异是由于岛屿的质量 影响，或者它们是否是大规模空间梯度的一部分。 正在收集水文、营养和氧气数据， 分析，以确定结构的程度， 在夏威夷附近和阿罗哈站是典型的北太平洋 中央环流，以及是否有任何差异确定可能 在JGOFS中很重要。

Data from the North Pacific Gyre will be examined to determine the degree of variability normal to the gyre, and the extent to which the area around Hawaii is typical of the gyre. A preliminary analysis of historical data suggests that differences may exist in upper ocean near Hawaii with respect to the characteristic structure seen on long transects and over many years at the Climax Station, about 750 km north of Hawaii. It is not known whether these tentatively-identified differences are due to island mass effects, or if they are part of a large-scale spatial gradient. Hydrographic, nutrient and oxygen data are being gathered and analyzed in order to determine the extent to which the structure near Hawaii and at station Aloha is typical of the North Pacific central gyre, and whether any differences identified are likely to be important in the context of JGOFS.
