Groote Eylandt Environmental Survey 2016, Northern Territory (ALC)

Towed Video transects + Digital Stills
Stereo BRUVS
CTD
Multibeam
Sediment Samples

RV Solander completed a broad-scale multibeam survey of the Groote Eylandt Indigenous Protection Aarea (IPA) covering as much of the IPA from the 15m isobath to the nominated Anindilyakwa Land Council (ALC) IPA boundary for sea country as possible, based on an approximately 1.2km grid. In addition running towed video transects of ~1.5km length for benthic communities and deploying stereo BRUVs units to assess fish diversity and abundance in a subset of the area surveyed was completed. Surface sediments were collected to establish baseline/background environmental conditions for metals and other selected contaminants.

The project comprises seven different components across several years that together will provide the data required to produce benthic habitat maps of the Groote Eylandt declared IPA. Each of these components will be completed through collaborations between the AIMS and ALC Staff and the Rangers.

沉积物样品

“索兰德号”研究船（RV Solander）以约1.2千米的网格为布设基准，对格鲁特岛原住民保护区（IPA）开展了大范围多波束测深调查，尽可能覆盖该保护区从15米等深线至阿尼迪利亚克瓦土地委员会（ALC）划定的海洋领地保护区边界的全部区域。此外，团队还完成了总长约1.5千米的拖曳视频样带布设，用于调查底栖生物群落，并部署立体诱饵式远程水下视频系统（Stereo BRUVS），以评估调查区域内部分片区的鱼类多样性与种群丰度。研究人员同步采集表层沉积物样品，以建立金属与其他选定污染物的基线环境与背景环境条件数据库。

本项目历时数年，包含七个独立研究组分，所有数据将共同支撑格鲁特岛已划定原住民保护区（IPA）底栖生境地图的绘制工作。所有研究组分均由澳大利亚海洋科学研究所（AIMS）、阿尼迪利亚克瓦土地委员会工作人员与原住民土地守护员协同完成。
