title: X-ray fluorescence (XRF) data of sediment core GeoB24351-1, 10 kV run

description: X-Ray fluorescence (XRF) scans were carried out for core GeoB24351-1 (Gelendzhik MV; 0-284 cm) in 10 mm steps downcore on the split core surface of the archive half with the XRF Core Scanner III (AVAATECH Serial No. 12) at MARUM – Center for Marine Environmental Sciences in Bremen. To avoid contamination of the XRF measurement unit and the desiccation of the sediment, the split core was covered with a 4 µm thin SPEXCerti Ultralene1 foil. Reported data was acquired with a SGX Sensortech Silicon drift detector (Modul S SiriusD®D65133Be-INF with 133 eV X-ray resolution), a Topaz-X High-Resolution Digital MCA, and an Oxford Instruments 100 W Neptune X-Ray tube with rhodium (Rh) target material. Data were obtained during three runs at 50 kV (1st run), 30 kV (2nd run) and 10 kV (3rd run). Processing of raw data took place by the analysis of X-ray spectra by an iterative least square software package from Canberra Eurisys (WIN AXIL).

Therefore highlyrecommended to (only) work with elemental ratios from the acquired datasets.Please also note: Ba*: small peaks only, general low total counts; (Sr,Rb,Zr,Br)**: better in30 kV run; (Nb, Mo, Pb)***: please validate the higher peaks standing out from a differentchemical method

description: The samples are retrieved from sediment core GeoB24310-1 (Napoli MV; 0-280 cm) in the Olimpi mud volcano field, located south of Crete at the Mediterranean Ridge accretionary complex. Major and minor element concentrations were measured at MARUM by ICP-OES and Metrohm ion chromatography and on selected samples. On board, 5 to 10 ml of pore water were extracted from the splitted cores every 5 to 20 cm during using rhizon samplers.

title: Effect of suspended microplastics on larval survival of the cold-water scleractinian coral Desmophyllum pertusum

description: We report the results of a short-term experiment testing the effects of microplastics (MP) on the larvae of the cold-water coral Desmophyllum pertusum (syn. Lophelia pertusa). The experiment was conducted at the Tjärnö Marine Laboratory Facilities (University of Gothenburg, Sweden). To simulate MP pollution, we used 6 μm yellow-green fluorescent polystyrene microbeads (catalog no: 17156, Polysciences). The experimental design consisted of three treatments: control treatment with (1) no MP addition (0 MP/mL), (2) addition of 1000 pristine MP/mL, and (3) addition of 1000 biofouled MP/mL. Larvae were exposed to the different treatments in 75 mL culture flasks mounted on a rotating plankton wheel to keep sediments in suspension. After a 24-hour period, the potential impact of MP on larval survival was analyzed.

title: Combined effect of ocean acidification and bottom trawling on embryo size of the scleractinian cold-water-coral Desmophyllum pertusum

description: We report the results of a series of experiments investigating the combined effects of ocean acidification and suspended natural benthic sediments (NS) generated during bottom trawling on the early life stages of the cold-water coral Desmophyllum pertusum (syn. Lophelia pertusa). The experiment was conducted at the Tjärnö Marine Laboratory Facilities (University of Gothenburg, Sweden). For each experiment, the larvae/embryos were exposed to four different treatments: (1) current pCO2 (control): mimicking present-day pCO2/pH condition (pCO2 400 µatm; ambient pHT: 8.01), (2) high pCO2: a scenario reflecting the IPCC RCP8.5 prediction (pCO2 1000 µatm; low pHT: 7.63), (3) current pCO2 + NS (5 mg/L), and (4) high pCO2 + NS (5 mg/L): with the introduction of natural benthic sediments (NS) at a concentration of 5 mg/mL. The NS were collected at ~130 m water depth from a regularly trawled soft bottom close to the reef site of Säcken in the Northern Koster-fjord in Sweden, and the grain sizes ≤ 63 μm were used for the experiment. Embryos and larvae were exposed to the different treatments in 75 mL culture flasks mounted on a rotating plankton wheel to keep sediments in suspension. In this first experiment, embryos were exposed for 48 hours to assess potential impacts on larval survival, development from the first division to the blastula stage, and developmental abnormalities. This dataset presents the results for embryo sizes.

This dataset presents the results for larval swimming speeds under long-term exposure.
