IMOS - Southern Ocean Time Series (SOTS) - Annual Reports: 2006/2007

The Southern Ocean Time Series (SOTS) is a Sub-facility of Australia’s Integrated Marine Observing System (IMOS), which is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). IMOS is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent. The primary focus is sustained observing of ocean properties and processes important to climate, carbon cycling, and ocean productivity.

SOTS consists of deep ocean moorings deployed in Subantarctic waters southwest of Tasmania, equipped with autonomous sensors and sample collectors. The SOTS moorings are serviced annually - the existing moorings are recovered and new moorings are deployed. Some sensor data is transmitted from the moorings via satellite in near real time. Other sensor data and samples are recovered during the annual service visit.

For each year, three reports are issued:
Report 1. Overview of mooring voyages, dates, locations, designs, instruments
Report 2. Samples from moored and shipboard sample collections
Report 3. Sensors mounted on the moorings moored and shipboard

These reports focus on metadata, i.e. descriptions of the moorings, sensors, samplers, and their deployment, recovery, processing, analysis and curation. Pointers are provided to supporting information from voyage reports and to on-line sources of the data. Shipboard sensor and sample measurements made during the service visits are also described.

Report 1. Overview - describes the deployment and recovery of the moorings. It provides their locations, drawings of their designs, and lists of each instrument deployed and the variables measured. It also summarizes ancillary measurements and sample collections made during the deployment and recovery voyages.

Report 2. Samples - describes 3 main types of samples and associated composition measurements:
1. Sediment trap samples collected by the Subantarctic Zone (SAZ) mooring.
2. Water samples collected by the RAS water sampler deployed on either the Pulse or Southern Ocean Flux Station (SOFS) mooring, and collected by the TM sampler deployed on the SOFS mooring.
3. Samples collected with other devices during the SOTS service voyages, e.g. from CTD Niskin bottles, in-situ pumps, continuous plankton recorders, and nets.
Note that not all these sample types were collected in any given year.

Report 3.Sensors provides:
1. Metadata on the sensor types, mounting, set-up, data availability and QC. This information is organized in tables for each mooring.
2. Links to access on-line sensor data from all SOTS moorings in the 2006-2007 year.
3. Description of and links to shipboard sensors records used for comparison to the moored sensors - note that Report 1. Overview provides links for standard shipboard sensors, and here we focus on additional sensor efforts with value for SOTS mooring sensor evaluations.

This metadata record represents the reports for the 2006/2007 research season.

南大洋时间序列（Southern Ocean Time Series, SOTS）是澳大利亚综合海洋观测系统（Australia’s Integrated Marine Observing System, IMOS）的下属分支设施，该系统由国家协同研究基础设施战略（National Collaborative Research Infrastructure Strategy, NCRIS）提供支持。IMOS由多机构组成的联盟以非法人联合运营体形式运营，塔斯马尼亚大学担任牵头机构。其核心研究方向为对气候、碳循环及海洋生产力相关的关键海洋属性与过程开展长期持续观测。

SOTS由部署于塔斯马尼亚西南亚南极水域的深海锚系组成，配备自主传感器与样品采集装置。该锚系系统每年接受一次维护作业：回收现有锚系并部署新的锚定装置。部分传感器数据可通过卫星实现近实时传输，其余传感器数据与采集的样品则在年度维护航次中回收。

每年将发布三份报告：
"Report 1. 锚定航次概况、日期、站位、设计与仪器"
"Report 2. 锚定与船载采集的样品"
"Report 3. 锚定及船载搭载传感器"

上述报告聚焦于元数据（metadata），即锚系、传感器、采样器及其部署、回收、处理、分析与管理的相关描述。报告中会提供航次报告辅助信息及数据在线来源的链接，同时也会对维护航次期间获取的船载传感器与样品测量数据进行说明。

"Report 1. 概况" 部分阐述锚系的部署与回收流程，提供其站位信息、设计图纸，列出每台搭载的仪器及所测量的变量，同时总结部署与回收航次期间开展的辅助测量与样品采集工作。

"Report 2. 样品" 部分介绍三类主要样品及相关成分测量内容：
1. 亚南极区（Subantarctic Zone, SAZ）锚系采集的沉积物捕获器样品
2. 搭载于Pulse锚系或南大洋通量站（Southern Ocean Flux Station, SOFS）锚系的RAS水样采集器，以及搭载于SOFS锚系的TM采样器采集的水样
3. SOTS维护航次期间通过其他设备采集的样品，例如温盐深剖面仪（Conductivity Temperature Depth, CTD）尼斯金采水器、原位泵、连续浮游生物记录仪及网具采集的样品。
注：并非每年都会采集上述全部类型的样品。

"Report 3. 传感器" 部分提供以下内容：
1. 各类传感器的元数据，包括类型、安装方式、设置情况、数据可用性与质量控制（Quality Control, QC）。该信息将按每个锚系以表格形式整理。
2. 2006-2007年度所有SOTS锚系的在线传感器数据访问链接。
3. 用于与锚定传感器比对的船载传感器记录的说明与链接——需注意，"Report 1. 概况"已提供标准船载传感器的相关链接，本报告重点聚焦可用于SOTS锚定传感器评估的额外传感器工作成果。

本元数据记录对应2006/2007研究季的相关报告。
