Microscopy imaging of live Antarctic krill (Euphausia superba)

Microscopy imaging of live Antarctic krill using a Leica M205C dissecting stereo-microscope with a Leica DFC 450 camera and Leica LAS V4.0 software. Krill were held in a custom made 'krill trap', details provided in manuscript in section eight of this form.

The data are available as a single video file.

These data are part of Australian Antarctic Science (AAS) projects 4037 and 4050.

Project 4037 - Experimental krill biology: Response of krill to environmental change
The experimental krill research project is designed to focus on obtaining life history information of use in managing the krill fishery - the largest Antarctic fishery. In particular, the project will concentrate on studies into impacts of climate change on key aspects of krill biology and ecology.

Project 4050 - Assessing change in krill distribution and abundance in Eastern Antarctica
Antarctic krill is the key species of the Southern Ocean ecosystem. Its fishery is rapidly expanding and it is vulnerable to changes in climate. Australia has over a decade of krill abundance and distribution data collected off Eastern Antarctica. This project will analyse these datasets and investigate if krill abundance and distribution has altered over time. The results are important for the future management of the fishery, as well as understanding broader ecological consequences of change in this important species.

采用徕卡M205C体视解剖显微镜（Leica M205C dissecting stereo-microscope）搭配徕卡DFC 450相机（Leica DFC 450 camera）及徕卡LAS V4.0软件（Leica LAS V4.0 software），对活体南极磷虾开展显微成像实验。实验所用磷虾饲养于定制的“磷虾诱捕器”中，相关细节详见本稿件第8章节。

本数据集以单个视频文件的形式对外提供。

本数据集隶属于澳大利亚南极科学（Australian Antarctic Science, AAS）项目4037与4050。

项目4037——实验性磷虾生物学：磷虾对环境变化的响应
本实验磷虾研究项目旨在获取可用于指导磷虾渔业管理的生活史相关信息，该渔业是南极规模最大的捕捞产业。本项目将重点聚焦气候变化对磷虾生物学与生态学关键特征的影响研究。

项目4050——评估南极东部海域磷虾分布与丰度变化
南极磷虾是南大洋生态系统的关键物种类群。其渔业正处于快速扩张阶段，且极易受到气候变化的影响。澳大利亚已在南极东部海域积累了十余年的磷虾丰度与分布观测数据。本项目将对这些数据集进行系统性分析，探究磷虾丰度与分布是否随时间发生改变。研究结果不仅可为该渔业的未来管理提供支撑，同时也有助于理解这一关键物种种群变化所引发的更广泛生态后果。
