2016 SoE Marine Chapter - Case Study - Plankton and climate change

The Marine chapter of the 2016 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Case Study "Plankton and climate change". The full Case Study, including figures and tables (where provided), is attached to this record. Where available, the Data Stream(s) used to generate this Case Study are accessible through the "On-line Resources" section of this record.----------------------------------------DESCRIPTION OF THE FOCUS OF THE CASE STUDYPlankton is the foundation of the marine food web and supports nearly all life in our oceans. Plankton species are sensitive indicators of ecosystem health and climate change because they are abundant, short-lived, not harvested, and sensitive to changes in temperature, acidity and nutrients.ISSUES OF IMPORTANCEOn local scales plankton are sensitive to eutrophication, over regional scales to invasive species and fisheries, and over large continental scales to climate change. There is growing evidence from Australia that plankton communities are being altered by climate change and this is likely resonate up food webs to higher trophic levels.DATA STREAM(S) USED IN CASE STUDYIMOS plankton data – both from the National Reference Stations and the Australian Continuous Plankton Recorder survey.

2016年《环境状况》（State of the Environment, SoE）报告的海洋章节，整合了多套依托海洋观测数据流构建的专家模板。本元数据记录针对案例研究"浮游生物与气候变化"进行说明。本案例研究的完整内容（含已提供的图表与表格）已附加至本记录。若有可用数据源，用于生成该案例研究的观测数据流可通过本记录的"在线资源"板块获取。

案例研究核心内容说明
浮游生物是海洋食物网的基础，支撑着海洋中几乎所有生命活动。浮游生物类群丰富、生命周期短促、未被捕捞利用，且对温度、海水酸度与营养盐变化极为敏感，因此是生态系统健康状况与气候变化的理想敏感指示物。

重要议题
在局地尺度上，浮游生物对富营养化响应敏感；区域尺度下，其受入侵物种与渔业活动的影响显著；而在大型陆架尺度上，则对气候变化呈现出明确的响应。澳大利亚已有越来越多的研究证据表明，气候变化正在改变浮游生物群落结构，这一变化可能通过食物网逐级传递至更高营养级，进而引发连锁生态影响。

本案例研究使用的数据流
IMOS浮游生物数据——包含国家参考站（National Reference Stations）及澳大利亚连续浮游生物记录仪（Australian Continuous Plankton Recorder）调查所获取的观测数据。
