Meiofauna abundances from ROV pushcore samples during SONNE cruise SO242/2@en

This dataset contains meiofauna abundance data collected from ROV pushcore samples (PUC) in disturbed areas of the DISCOL experimental area (Peru Basin), collected onboard RV Sonne during expedition SO242/2 in 2015. Meiofauna taxa have been counted and identified at different microhabitats within old disturbance tracks in the area, created by a plough harrow to mimick deep-sea mining impact. Each push core has been subjected to further division in vertical sediment slices (0-1 cm, 1-2 cm and 2-5 cm) and meiofauna has been counted in each separate slice. […]本数据集涵盖2015年松恩号科考船（RV Sonne）执行SO242/2航次期间，于DISCOL实验区（秘鲁盆地）受扰动区域采集的遥控水下机器人（Remotely Operated Vehicle, ROV）推送岩芯（pushcore samples, PUC）样本的小型底栖生物（meiofauna）丰度数据。研究人员针对该区域内由犁耙模拟深海采矿影响所形成的旧扰动轨迹内的不同微生境，完成了小型底栖生物类群的计数与鉴定工作。每根推送岩芯均被进一步划分为沉积物垂直切片（0-1 cm、1-2 cm及2-5 cm），并对每个独立切片中的小型底栖生物进行了计数。[…]
