IMOS - Moorings - Hourly time-series product

Integrated Marine Observing System (IMOS) have moorings across both it's National Mooring Network and Deep Water Moorings facilities. The National Mooring Network facility comprises a series of national reference stations and regional moorings designed to monitor particular oceanographic phenomena in Australian coastal ocean waters. The Deep Water Moorings facility (formerly known as the Australian Bluewater Observing System) provides the coordination of national efforts in the sustained observation of open ocean properties with particular emphasis on observations important to climate and carbon cycle studies, with selected moorings from its Deep Water Arrays sub-facility providing data to this collection.
This collection represents the hourly aggregated time-series product, which combines selected variables measured by all the instruments deployed at a site, binning the values into a fixed one-hour interval. Only good-quality measurements (according to the automated quality-control procedures applied by the National Mooring Network) are included.
The parameters are: temperature, salinity, dissolved oxygen, chlorophyll estimates, turbidity, down-welling photosynthetic photon flux (PAR), and current velocity, accompanied by depth and pressure when available. The observations were made using a range of temperature loggers, conductivity-temperature-depth (CTD) instruments, water-quality monitors (WQM), acoustic Doppler current profilers (ADCPs), and single-point current meters.

综合海洋观测系统（Integrated Marine Observing System，IMOS）的国家锚定观测网络（National Mooring Network）与深水锚泊设施（Deep Water Moorings）两大板块均布设了锚系观测站。其中，国家锚定观测网络包含一系列国家基准观测站与区域锚系观测站，旨在监测澳大利亚近岸海域的特定海洋学现象。深水锚泊设施前身为澳大利亚远海观测系统（Australian Bluewater Observing System），负责统筹全国范围内的开放海域参数长期观测工作，重点关注对气候与碳循环研究具有重要价值的观测数据；其下属深水阵列子设施（Deep Water Arrays sub-facility）中的精选锚系观测站将为该数据集提供观测资料。

本数据集为逐小时聚合的时间序列产品，整合了单个观测站点所有部署仪器所测得的精选变量，并将观测值按固定1小时间隔进行分箱聚合。仅纳入符合国家锚定观测网络自动质量控制流程判定的优质观测数据。

观测参数包括：温度、盐度、溶解氧、叶绿素估算值、浊度、下行光合有效辐射通量（down-welling photosynthetic photon flux，PAR）以及海流流速；若有可用数据，还将附带水深与压强信息。本次观测由多款仪器完成，包括温度记录仪（temperature loggers）、温盐深仪（conductivity-temperature-depth，CTD）、水质监测仪（water-quality monitors，WQM）、声学多普勒流速剖面仪（acoustic Doppler current profilers，ADCPs）以及单点海流计（single-point current meters）。
