Typical depth profiles of Jerlov water types have been derived to characterize the clarity of the world's oceans. Measured values of the downwelling diffuse attenuation coefficient, taken from a world-wide database, were quantitatively analyzed. Depth profiles were extracted from more than 2500 data collection campaigns, consisting of the closest-matching Jerlov water types at the uppermost layer (0–10 m) and the corresponding Jerlov water types at deeper depth layers down to 200 m. A table of “typical” depth profiles for the 10 Jerlov water types was generated based on the maximum campaign count at each depth layer. This new ocean classification will find use in applications where modeling of typical ocean waters requires the depth-dependence of clarity to be accounted for.

杰洛夫水类型的深度剖面

杰洛夫水类型的典型深度剖面已得出，以表征世界海洋的透明度。对取自全球数据库的下降流扩散衰减系数的测量值进行了定量分析。深度剖面是从 2500 多个数据收集活动中提取的，包括最上层 (0-10 m) 的最匹配的 Jerlov 水类型以及更深至 200 m 的更深深度层的相应 Jerlov 水类型。根据每个深度层的最大活动计数生成了 10 种 Jerlov 水类型的“典型”深度剖面表。这种新的海洋分类将用于典型海水建模需要考虑清晰度的深度依赖性的应用中。
