IMOS - ABOS Facility Southern Ocean Time Series (SOTS) Subantarctic Zone Sediment Trap Moorings (SAZOTS) (deployments from 1998)

Sediment traps (IMOS platform code:SAZOTS) are cones which intercept and store falling marine particles in collection cups. The particles consist of a range of material including phytoplankton, zooplankton, faecal pellets, and dust. Each trap collects a time series of samples. The sediment traps are from deep moorings in the Southern Ocean, typically at 47S, 54S, and 61S and at around 140 degrees East. Each mooring typically has 2-3 traps between 800m and 3800m below sea-level.\n\nThe samples are size fractionated into 1mm fractions using a 1mm sieve. Various chemical analyses and observations have been made on the 1mm fraction from 1998 to 2012 are available here for download. After processing, data from IMOS deployments will be made available.\n\nPreliminary biogeochemical data for the sediment traps on the 2008/09 mooring are available. These preliminary data are indicative only and have not been quality controlled. Analysis of the samples is ongoing. A full dataset for this sediment trap deployment will be made available through the IMOS Ocean Portal when analysis is complete.

沉积物捕集器（IMOS平台代码：SAZOTS）为锥形装置，用于截留并收集沉降的海洋颗粒物至收集杯内。这类颗粒物涵盖多种组分，包括浮游植物、浮游动物、粪球粒以及粉尘。每套捕集器均可获取连续的时间序列样本。本次使用的沉积物捕集器布放于南大洋的深海锚系平台，典型站位坐标为南纬47°、54°、61°，东经约140°。每套锚系平台通常搭载2至3台捕集器，布设水深介于海平面下800米至3800米之间。

研究人员采用1毫米孔径的筛网，将样本按粒径分为1毫米级分样。1998年至2012年间针对1毫米级分样开展的各类化学分析与观测数据，可在此处下载获取。待数据处理完成后，IMOS布放项目的相关数据亦将对外发布。

2008/2009年度锚系平台配套沉积物捕集器的初步生物地球化学数据现已对外开放。此类初步数据仅作参考，尚未经过质量控制流程。当前样本分析工作仍在进行中。待全部分析工作完成后，本次沉积物捕集器布放项目的完整数据集将通过IMOS海洋门户网站对外发布。
