title: Stable dissolved silicon isotopes measured on CTD and underway samples during AMK73 in the Laptev Sea

description: Dissolved stable silicon isotopes were determined in seawater samples collected during the 73rd expedition onboard RV Akademik Mstislav Keldysh (AMK73) in the Laptev Sea in October 2018 under ice free conditions. Seawater samples were filtered inline from Niskin bottles or the ship's underway system, acidified to 0.1% v/v with HCl and kept at 4°C until analysis on land. Samples were measured for δ29Si(OH)4 with reference to international reference material NBS28 on a Nu Plasma II MC-ICP-MS (The University of Edinburgh, School of Geosciences) using the MAGIC co-precipitation method and purified through column chemistry. International standards BigBatch, ALOHA300 and ALOHA1000 were run alongside seawater samples for inter-comparability. Final values were converted to δ30Si(OH)4 using the conversion factor of 1.96 for comparability. Reproducibility is 0.05 and 0.1‰ for δ29Si(OH)4 and δ30Si(OH)4 respectively. This dataset includes salinity, silicic acid concentrations and stable silicon isotope signatures of seawater, which provides useful information on the silicon biogeochemical cycle of the Laptev Sea, as influenced by the Lena river.

title: Concentrations and compound specific carbon isotope (δ13C) of n-alkanes in 25 surface sediments of Futou Lake in the Yangtze floodplain China

description: This data compiles concentrations and compound specific carbon isotope (δ13C) of n-alkanes in 25 surface sediments of Futou Lake in the Yangtze floodplain China. The surface sediments were collected using a Kayak gravity corer and the top 1 cm sediments were sampled in April 2023. Concentrations of n-alkanes were analysed using a Shimadzu GC2010 gas chromatography (GC) equipped with a flame ionization detector (FID) and a DB-5MS column (30 m × 0.25 mm × 0.25 μm film thickness). Compound specific carbon isotope (δ13C) of n-alkanes were analyzed using a Finnigan Trace GC instrument coupled with a Finnigan Delta XP isotope ratio mass spectrometer (GC-IRMS). Both the concentrations and compound specific carbon isotope (δ13C) of n-alkanes were analysed at State Key Laboratory of Biogeology and Environmental Geology, China University of Geosciences. Each sample of the compound specific carbo isotopes was analyzed at least twice with peak intensities (m/z 44) &gt; 500 mv and the standard deviation &lt; 0.5‰ were identified as reliable results. Results were reported in the delta notation (‰) relative to Vienna Peedee Belemnite (VPDB).

title: Oxygen consumption and inorganic nutrient fluxes of deep-water hexactinellid and demosponges from New Zealand collected during SONNE cruise SO254

description: During R/V Sonne cruise SO254 around New Zealand (January-February 2017), deep-sea sponges were incubated in-situ and ex-situ to measure oxygen consumption, inorganic nutrient fluxes, bacterial and phospholipid-derived fatty acid (PLFA) composition. Inorganic nutrient (ammonium, nitrite, nitrate, silicate, phosphate) fluxes and oxygen consumption in the sponge incubations were calculated by linear regression analyses of concentrations measured at the begin and the end of the 5 h incubations (nutrient fluxes) or of continuous measurements of oxygen concentrations (oxygen consumption).

title: Biogeochemical and phospholipid-derived fatty acid (PLFA) composition of deep-water hexactinellid and demosponges from New Zealand collected during SONNE cruise SO254

description: During R/V Sonne cruise SO254 around New Zealand (January-February 2017), deep-sea sponges were incubated in-situ and ex-situ to measure oxygen consumption, inorganic nutrient fluxes, bacterial and phospholipid-derived fatty acid (PLFA) composition. The biogeochemical composition of 4 shallow-water and deep-water sponge species were determined after the cruise by measuring the organic and total carbon and nitrogen content of freeze-dried sponge tissue and the stable isotopic composition (δ13C, δ15N) of the tissue. Phospholipid-derived fatty acids (PLFAs) of freeze-dried sponge tissue were extracted using a modified Bligh-Dyer extraction protocol and subsequently the PLFA concentrations were measured using gas chromatography flame ionization detection (GC-FID).

title: Major elements of sediment core MD18-3569 from the Penghu Canyon in the northeastern South China Sea

description: This dataset provides major element compositions of marine sediments over the past 32 kyr at HydroSed Core MD18-3569 on the Penghu Canyon in the northeastern South China Sea. The data include major element compositions and calibrated CaO* content (CaO associated with silicate fractions of the sample). The samples were collected at 5 cm resolution for the upper 3 m and 2.5 cm resolution for the 3–8 m depth interval at Core MD18-3569 (22°09.30'N, 119°49.24'E; 1320 m water depth) retrieved from the HydroSed cruise aboard the R/V Marion Dufresne in 2018. A total of 364 samples were analyzed at the State Key Laboratory of Marine Geology, Tongji University (Shanghai). Major elements were obtained on pressed pellets of salt-removed bulk samples by X-ray fluorescence (XRF) using a PANalytical Axios spectrometer. Standards of GSD-15, GSD-16, and GSR-6 were used to control the analysis precision with an average deviation of less than ±2% for all major elements. Results of major elements were expressed as their oxides (%) as absolute bulk content of samples.

title: XRF-scanning elemental data and core descriptions from sediment cores obtained southwest off the Cabo Verde archipelago

description: Semi-quantitative elemental concentrations from X-ray fluorescence (XRF) scans were measured for six sediment cores obtained during the iMirabilis2 expedition off Cabo Verde. The analyses were conducted using an Avaatech XRF core scanner at the Institute of Geosciences, Christian-Albrechts-University, Kiel University. The sediment from the core halves was smoothed with a spatula to create an even scanning surface, which was then covered with a thin film foil to prevent contamination. The resolution was set to 0.5 cm. The elements Mg, Al, Si, S, Cl, K, Ca, Ti, Mn, Fe, Co, Cu and Zn were analysed with the 10-kV setting (200 µA, 10s acquisition time, no filter) and the elements Br, Rb, Sr, Zr and Pb were analysed with the 30-kV setting (1000 µA, 20s acquisition time, Pd-thick filter). Raw X-ray spectra were converted into area counts using the iterative least-square software package WIN_AXIL from Canberra Eurisys. Elements that yielded negative area values are excluded. 'Ka' and 'La' after the element denote the energy state of the electrons being measured in the atom, with level 'Ka' being closest to the nucleus with the lowest energy state, while level 'La' is farther from the nucleus and has a higher energy state. Units are reported as area counts per second for the spectral peaks of each element, alongside chi-squares and standard deviations from the models. Additionally, pictures and lithological descriptions of the six cores are included.

title: Growth responses of Skeletonema marinoi-dohrnii complex and Chattonella marina under different nitric oxide (NO) supply rates

description: Growth responses of Skeletonema marinoi-dohrnii complex and Chattonella marina isolated from Japanese coastal waters were monitored under different nitric oxide (NO) supply rates using a variable-volume repeated fed-batch (VRFB) culture system. Culture experiments for S. marinoi-dohrnii complex were performed at three NO levels: low, medium, and high. The average NO supply rates at the low, medium, and high NO levels were 1.4, 5.4, and 28 pM/s, respectively. In the C. marina culture experiments, 2.5 pM/s NO supply rate (low-medium treatment) was used instead of 28 pM/s. In both experiments, a treatment feeding deoxygenated f/2 medium without NO was used as the control. The S. marinoi-dohrnii complex and C. marina were cultured in the VRFB culture system for 3 days. To examine the recovery from NO-induced growth inhibition, phytoplankton growth was monitored for several days after the termination of 3-day NO supply.

title: Crustaceans and fish abundances and species at and around artificially introduced tetrapod fields in the southern North Sea, 2009

description: The micro-scale spatial distribution patterns of a demersal fish and decapod crustacean assemblage were assessed in a hard-bottom kelp environment in the southern North Sea. Using quadrats along line transects, we assessed the in situ fish and crustacean abundance in relation to substratum types (rock, cobbles and large pebbles) and the density of algae. Six fish and four crustacean species were abundant, with Ctenolabrus rupestris clearly dominating the fish community and Galathea squamifera dominating the crustacean community. Differences in the substratum types had an even stronger effect on the micro-scale distribution than the density of the dominating algae species. Kelp had a negative effect on the fish abundances, with significantly lower average densities in kelp beds compared with adjacent open areas. Averaged over all of the substrata, the most attractive substratum for the fish was large pebbles. In contrast, crustaceans did not show a specific substratum affinity. The results clearly indicate that, similar to other complex systems, significant micro-scale species–habitat associations occur in northern hard-bottom environments. However, because of the frequently harsh environmental conditions, these habitats are mainly sampled from ships with sampling gear, and the resulting data cannot be used to resolve small-scale species–habitat associations. A detailed substratum classification and community assessment, often only possible using SCUBA diving, is therefore important to reach a better understanding of the functional relationships between species and their environment in northern temperate waters, knowledge that is very important with respect to the increasing environmental pressure caused by global climate change.
