Southern Surveyor Voyage SS 03/2005 Sediment Data

The dataset comprises sediment data for samples taken from box core deployments completed on research voyage SS 03/2005. The recorded sediment properties include gravel, sand, mud and carbonate content. The survey design was a natural experiment (i.e. control-impact, but not before-after) to test the long-term, broadscale effects of prawn fishing on non-target species and habitats. Deployments were stratified by fishing intensity (three strata) and day/night. The survey was repeated in three regions: (a) north of Groote Eylandt, (b) north-east of the Vanderlins, and (c) north of Mornington Island.本数据集涵盖SS 03/2005号科考航次（research voyage SS 03/2005）中完成的箱式采芯部署（box core deployments）所采集的沉积物样品数据。所记录的沉积物特征参数包括砾石、砂、泥及碳酸盐含量。本次调查采用自然实验设计，即控制-影响型实验但未设置前后对照，旨在探究虾类捕捞对非目标物种及其栖息地的长期、大范围影响。采样部署按捕捞强度（分为三个层级）与昼夜时段进行分层。该调查在三个区域重复开展：(a) 格罗特埃兰岛（Groote Eylandt）以北海域，(b) 范德林群岛（Vanderlins）东北海域，(c) 莫宁顿岛（Mornington Island）以北海域。
