title: Lipidomics analysis (MGDG) from water bottle samples in and around a cyclonic eddy during METEOR cruise M156, off Mauritania

description: This dataset includes lipidomics data over the surface mixed layer (0-35 m depth) of eleven stations with five of them inside or in the vicinity of a mesoscale cyclonic eddy that formed off Mauritania along a 900 km zonal corridor between Mauritania and the Cabo Verde islands in the eastern Tropical North Atlantic during the M156 cruise on the RV Meteor from July 3rd to August 1st 2019. Lipid samples were collected onto 0.22 µm Durapore filters (Millipore) and immediately flash-frozen and stored at −80 °C until processing. Extraction was performed using a modified Bligh and Dyer (Bligh and Dyer, 1959; https://doi.org/10.1139/o59-099) method described in Popendorf et al. (2013; https://doi.org/10.1007/s11745-012-3748-0). Lipid extracts were analyzed by HPLC-ESI-MS/MS on a Bruker maXis Ultra-High Resolution quadrupole time-of-flight tandem mass spectrometer (Bruker Daltonik, Bremen, Germany) equipped with an ESI ion source operating in positive mode. The HPLC-ESI-MS method is described in Wörmer et al., 2013 (https://doi.org/10.1016/j.orggeochem.2013.03.004). Lipids were identified by retention time as well as accurate molecular mass and isotope pattern match of proposed sum formulas in full scan mode and MS/MS fragment spectra. Lipid identities are resolved only to the level of lipid species, i.e., the sum of the properties of the substituents at both the sn-1 and sn-2 positions. After identification, quantification of analytes was performed using a series of standard curves, followed by normalization to concentration of an internal standard.

title: Porewater methane concentrations of deep sea sediment recovered along Gloria Fault (Atlantic Ocean) during METEOR cruise M162

description: Data set includes porewater methane concentrations of deep sea sediments, which were recovered along the Gloria Fault lines by gravity coring (GC) and multi coring (TVMUC) during Meteor cruise M162 (Hensen et al., 2020). Dissolved methane concentrations released from sampled sediment/porewater were evaluated concerning possible fluid/gas escape along fault structures.

title: Ridge ice salinity, temperature, density, oxygen and hydrogen isotope composition from the Ridgey McRidgeFace (RMRF) ridge site during MOSAiC leg 3 in April-May 2020

description: Sea-ice thickness, salinity, temperature, density, and stable water isotope composition were measured during surveys at the Ridgey McRidgeFace (RMRF) coring site during the MOSAiC expedition (leg 3). RMRF was a first-year ice ridge formed in March 2020. The ice cores were extracted either with a 9-cm (Mark II) or 7.25-cm (Mark III) internal diameter ice corers (Kovacs Enterprise, US). This data set includes data from coring site visits performed on 22 April 2020 and 05 May 2020 at RMRF in the MOSAiC Central Observatory (Kanzow and Damm, 2023). During each coring event, ice temperature was measured in situ from a separate temperature core, using Testo 720 thermometers in drill holes with a length of half-core-diameter at 5-cm vertical resolution. Ice bulk practical salinity was measured from melted core sections at 5-cm resolution using a YSI 30 conductivity meter. Ice density was measured using the hydrostatic weighing method (Pustogvar and Kulyakhtin, 2016) from a density core in the freezer laboratory onboard Polarstern at the temperature of -(16–18)°C. Relative volumes of brine and gas were estimated from ice salinity, temperature, and density using Cox and Weeks (1983) for ice colder than -2°C and Leppäranta and Manninen (1988) for ice warmer than -2°C.The data contains the event label (1), time (2), and global coordinates (3,4) of each coring measurement, coring site (5), and core type (6). Each core has its manually measured ice thickness (7), ice core length (8), and mean snow height (9). Each core section has the total length of its middle (10), top (11), and bottom (12) measured in situ. Each core section has the value of its practical salinity (13), as well as sea ice temperature (14), laboratory temperature (15), and ice density at the laboratory (16) and in situ (17) temperatures, brine volume fraction estimates (18), and gas volume fraction estimates at the laboratory (19) and in situ (20) temperatures. Some core sections have stable water isotopic values (21, 22). The location of ice sections relative to the nearby ridge void is described in comment (23). The locations of the coring sites are shown on the digital elevation map (Hutter et al., 2023).The stable oxygen isotopic compositions of the melted snow samples (δ18O) were determined in the central laboratory of the Swiss Federal Institute for Forest, Snow and Landscape, Birmensdorf, Switzerland with an Isotopic Water Analyzer IWA-45-ER (ABB - Los Gatos Research Inc., US). Measurement uncertainty for δ18O is ±1‰, the precision ± 0.5‰. All samples were measured in duplicate and averaged. The quality control was conducted with three standards for δ18O at 0.00‰, -12.34‰ and -55.50‰ and are presented as per mil difference relative to VSMOW (‰, Vienna Standard Mean Ocean Water).
