IMOS - System Description and Procedures for Moored Biogeochemical Measurements Manual

Australia’s Integrated Marine Observing System (IMOS) supports surface biogeochemical moorings at three sites on the Australian shelf to provide baseline data to assess trends and variability in ocean acidification (OA), CO2, salinity and temperature change. The three sites are at Wistari Channel, Heron Island, on the Great Barrier Reef (23.459°S, 151.927°E), off Maria Island, Tasmania (42.599°S, 148.234°E), and to the west of Kangaroo Island, South Australia (35.835°S, 136.451°E).

This document serves as the description and quality-control manual for the IMOS Acidification Moorings Sub-Facility, a component of IMOS's National Mooring Network. It includes details on mooring locations, mooring design, measurement sequences, QA/QC procedures, data calculation and reduction procedures, and sensor specifications. The quality-controlled datasets are accessible to the public through the AODN Portal and SOCAT. Users are encouraged to consult this document when utilising the data.

澳大利亚综合海洋观测系统（Integrated Marine Observing System, IMOS）在澳大利亚陆架的三个站点运维表层生物地球化学锚系观测系统，旨在提供基准数据，以评估海洋酸化（Ocean Acidification, OA）、二氧化碳、盐度与温度变化的趋势及变异性。三个站点分别位于大堡礁赫伦岛威斯塔里水道（23.459°S，151.927°E）、塔斯马尼亚州玛丽亚岛外海（42.599°S，148.234°E），以及南澳大利亚州袋鼠岛以西海域（35.835°S，136.451°E）。本文件为IMOS酸化锚系子设施（IMOS Acidification Moorings Sub-Facility）的说明与质量控制手册，该设施是IMOS国家锚定观测网络的组成部分。文件涵盖锚系站点位置、锚系设计、观测序列、质量保证与质量控制（QA/QC）流程、数据计算与归约流程，以及传感器规格参数。经质量控制的数据集可通过澳大利亚海洋数据门户（AODN Portal）与SOCAT向公众开放。建议用户在使用该数据时参阅本文件。
