Water current readings from the North East mooring in Jervis Bay (Honeymoon Bay): 13/9/90 - 30/10/90

A current meter mooring was deployed in the NE section of Jervis Bay (35.0623S, 150.7672E) between 13/9/90 and 30/10/90. This mooring held two S4 Interocean current meters at depths of 11.5m and 5.5m.

Each of these current meters provided two datasets. In the first, the meter integrates the signals over 2 minutes every 10 minutes, providing 10 min sample readings. The second decimated the samples using a running mean to provide hourly intervals.

The data provided includes the eastern and northern tidal components, speed, direction and temperature. The datasets providing the 10 minute sample values also give depth and salinity readings.

Users should be aware that there appears to be some distortion of data within these files. For example, the depth data recorded by the meter maintained around 11.5m produced negative values and also readings of 132m! Salinity readings from the 5.5m current meter are also missing for the start of the record.

**Unfortunately one dataset is missing from this collection: The decimated hourly intervals for the meter at 5.5m have not been located, and are therefore not provided in this record**

本研究于杰维斯湾（Jervis Bay）东北部海域（南纬35.0623°，东经150.7672°）布设了一套锚系海流计系统，布设时段为1990年9月13日至1990年10月30日。该锚系搭载了两台S4 Interocean型海流计，布设水深分别为11.5米与5.5米。
每台海流计均生成两套数据集：第一套为每10分钟对2分钟时长的观测信号进行积分，输出10分钟间隔的采样数据；第二套采用滑动平均法对原始采样值进行降采样，生成逐小时间隔的观测数据。
本次公开的数据包含东向与北向潮汐分量、流速、流向与水温。其中10分钟采样间隔的数据集还附带了水深与盐度观测值。
使用者需注意，部分数据文件存在明显失真问题。例如，布设水深约11.5米的海流计记录的水深数据出现负值，甚至出现132米的异常读数；此外，5.5米海流计的初始时段盐度观测数据存在缺失。
遗憾的是，本次数据集集合存在缺失项：5.5米海流计对应的逐小时降采样数据集尚未被找到，因此本记录未包含该部分数据。
本记录为父数据集ID为84d67460-2ae4-11dd-a735-00188b4c0af8的4个子数据集之一。用户可通过本记录下载一份详述本项目所有元数据记录结构与层级关系的PDF文档；同时还可下载一篇记录本次实验与研究结果的已发表工作论文PDF文档。
