    Description: This dataset includes meiofauna and macrofauna densities from inside plough tracks from a small-scale deep-sea mining experiment (DISCOL experiment) and reference sites in the abyssal plains in the Peru Basin. Additionally, biomass of bacteria and the uptake of phytodetritus by bacteria, nematodes and holothurians is shown for plough tracks and reference sites with and without holothurians.

    Description: During Sonne cruise SO242-2 six steel rings were inserted into undisturbed sediment at the southern reference site of the DISCOL experimental area using ROV Kiel 6000 (GEOMAR). Subsequently, on three of these steel rings a sediment dispenser was deployed to distribute 250 mL of crushed nodule substrate onto the ring surface area resulting in an added layer of approximately 2 cm. The sediment dispensers were left on the steel rings for one night to allow settlement of all particles. After the incubation time of eleven days each steel ring was subsampled with push cores (7.4 cm inner diameter) which were sliced in different depth layers (added substrate layer, 0-1 cm,1-2 cm and 2-5 cm sediment depth). Samples form meiofauna analysis were fixed in formaldehyde while samples for analysis of environmental parameters were stored frozen. In addition to morphological meiofauna analyses, internal copper concentrations were measured in 6 nematodes exposed to the crushed nodule substrate and 12 nematodes from undisturbed sediment by means of µ-X-ray fluorescence.

    Meiofauna abundances following a 94 h in-situ copper exposure during SONNE cruise SO242/2 (2017)
    PANGAEA
    Details
    Publication Date: 2023-07-10
    Description: During Sonne cruise SO242-2 six enclosure corrals (30*30 cm) were deployed in undisturbed sediment at the southern reference site of the DISCOL experimental area using ROV Kiel 6000 (GEOMAR). Artificial sediment was incubated at 2°C in filtered seawater (sediment effect) or in filtered seawater spiked with copper (copper effect; 1, 5, 10, or 20 mg Cu L-1) for 72 h prior to deployment and subsequently added on top of the deep-sea sediment inside the corrals. After approx. 94h of in-situ incubation, push cores (7.4 cm inner diameter) were taken inside the corrals and sliced in different depth layers (artificial sediment layer, 0-1 cm, 1-2 cm and 2-5 cm). Samples were fixed in formaldehyde and meiofauna was analysed in the lab of the Marine Biology group at Ghent university.
