IMOS - Southern Ocean Time Series (SOTS) - Annual Reports: 2009/2010

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, underway supply, 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 2009-10 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 2009/2010 research season.

南大洋时间序列观测站（Southern Ocean Time Series, SOTS）是澳大利亚综合海洋观测系统（Integrated Marine Observing System, IMOS）的子设施，由国家合作研究基础设施战略（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的形式开展运营，塔斯马尼亚大学担任牵头机构。该观测站的核心聚焦方向为持续观测与气候、碳循环及海洋生产力密切相关的海洋属性与过程。

SOTS由部署在塔斯马尼亚西南侧亚南极水域的深海锚系组成，搭载自主传感器与样品采集装置。SOTS锚系每年开展一次维护作业：回收现有锚系并部署新锚系。部分传感器数据通过卫星实现近实时传输，其余传感器数据与采集样品则在年度维护航次中回收。

每年将发布三份报告：
报告1：锚系航次概况、日期、站位、设计方案与搭载仪器
报告2：锚系与船载采集的样品
报告3：锚系与船载搭载的传感器

这些报告围绕元数据（metadata）展开，即对锚系、传感器、采样器及其部署、回收、处理、分析与管控的相关描述。报告中还会提供航次报告辅助信息及数据在线来源的检索指引，同时对维护航次中开展的船载传感器与样品测量工作进行说明。

报告1.概况：介绍锚系的部署与回收作业，提供其站位信息、设计图纸、所搭载仪器清单及测量变量列表，同时汇总部署与回收航次中开展的辅助测量与样品采集工作。

报告2.样品：介绍三大类样品及相关组分测量内容：
1. 亚南极区（Subantarctic Zone, SAZ）锚系采集的沉积物捕集器样品
2. 搭载于Pulse锚系或南大洋通量站（Southern Ocean Flux Station, SOFS）的RAS水质采样器，以及搭载于SOFS锚系的TM采样器采集的水样
3. SOTS维护航次中通过其他设备采集的样品，例如CTD-尼斯金采水器、走航补给系统、原位泵、连续浮游生物记录仪及网具采集的样品。
注：并非每年都会采集所有类型的样品。

报告3.传感器：
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）信息。该内容按每个锚系以表格形式进行整理。
2. 提供2009-2010年度所有SOTS锚系在线传感器数据的访问链接。
3. 介绍用于锚系传感器比对的船载传感器记录并提供相关链接：需说明，报告1.概况已提供标准船载传感器的链接，本部分重点聚焦于可用于SOTS锚系传感器评估的额外传感器相关工作。

本元数据记录对应2009/2010研究季的相关报告。
