title: Sea-ice dissolved inorganic carbon and total alkalinity during JARE57–60, AWECS, and SIPEX2 in the Southern Ocean

description: Sea-ice core sampling for dissolved inorganic carbon (DIC) and alkalinity (TA) were examined during JARE57–60 (57th–60th Japanese Antarctic Research Expedition in 2016–2019), AWECS (Antarctic Winter Ecosystem Climate Study in 2013), SIPEX2 (Sea Ice Physics and Ecosystems eXperiment-2 in 2012) in the Southern Ocean. See Sahashi et al. (2022), Tison et al. (2017), and Damm et al. (2016) for details of ice sampling for JARE57–60, AWECS, and SIPEX2, respectively. Ice cores were collected using an ice corer, and ice temperature was measured by inserting a needle-type temperature sensor into holes drilled into the core. Ice cores were segmented by saw. Ice sections were placed into gas tight bags (Smart bags PA, GL Sciences Inc., Japan), air within the bag was removed, and ice melted in the dark at +4°C. Then, ice meltwater was subsampled into glass vial for measurement of DIC, TA, and salinity. Immediately after subsampling for measurement of DIC and TA, a 6.0% (wt.) mercuric chloride (HgCl2) solution was added to stop biological activity. For analysis, samples were transported to Hokkaido University, Hokkaido, Japan. The DIC was determined by coulometry (Johnson et al., 1985; Johnson, 1992) using a home-made CO2 extraction system (Ono et al., 1998) and a coulometer (CM5012, UIC, Inc., Binghamton, NY, USA). The TA was determined by potentiometric titration (Dickson et al., 2007) using a TA analyzer (ATT-05, Kimoto Electric Co., Ltd., Japan). Both DIC and TA measurements were calibrated with reference seawater materials (KANSO Technos Co., Ltd., Osaka, Japan) traceable to the Certified Reference Material distributed by Prof. A. G. Dickson (Scripps Institution of Oceanography, La Jolla, CA, USA). The standard deviations of the DIC and TA measurements, calculated from 10 subsamples taken from reference water with a DIC value of 2039.4 μmol kg−1 and a TA value of 2311.6 μmol kg−1, were ±1.4 μmol kg−1 and ±1.2 μmol kg−1, respectively. The salinity was determined by conductivity sensor (Cond 315i, WTW GmbH, Germany) from DIC and TA samples.

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.

title: Clay mineralogy of sediment core SO121_KL42, southern Red Sea

description: We present high-resolution clay mineral data from the upper 8.30 m of marine sediment core KL42 from the southern Red Sea. The core was recovered at 15°54.9' N and 41°34.7' E from a water depth of 958 m during RV Sonne cruise SO121 in 1997. We investigated the carbonate-free sediment fraction &lt;2µm by X-ray diffraction, using a Rigaku Corp. miniflex system. Percentages of smectite, illite, chlorite, kaolinite and palygorskite were calculated. For details see Ehrmann and Schmiedl 2021.

description: We present high-resolution data on the carbonate and terrigenous matter contents from the upper 8.30 m of marine sediment core KL42 from the southern Red Sea.

Carbonate and terrigenous matter, respectively, have been calculated as weight difference after dissolving carbonate from the bulk sediment with acetic acid.

title: Grain size of terrigenous matter from sediment core SO121_KL42, southern Red Sea

description: We present detailed and high-resolution grain size data of the terrigenous matter from the upper 8.30 m of marine sediment core KL42, southern Red Sea. The core was recovered at 15°54.9' N and 41°34.7' E from a water depth of 958 m during RV Sonne cruise SO121 in 1997. After removing carbonate and organic matter, the grain size distribution was measured with a Beckman Coulter LS13320 laser particle analyzer (Beckman Coulter Life Sciences, Indianapolis, IN, USA). Volume percentages are given for 116 grain-size classes between 0.0004 mm and 2.0 mm. Concentrations of clay (&lt;0.002 mm), fine silt (0.002-0.0063 mm), medium silt (0.0063-0.02 mm), coarse silt (0.02-0.063 mm), fine sand (0.063-0.2 mm), medium sand (0.2-0.63 mm), and coarse sand (0.63-2.0 mm) were calculated.

title: Seawater carbonate chemistry of chamber experiment at volcanic CO2 vents off Shikine Island

description: Here, we investigated the effects of elevated carbon dioxide on macroalgal communities using volcanic carbon dioxide vents as a natural analogue of ocean acidification. Net community photosynthesis was assessed using chambers positioned on the seafloor as well as water mass dynamics monitoring.This dataset is included in the OA-ICC data compilation maintained in the framework of the IAEA Ocean Acidification International Coordination Centre (see https://oa-icc.ipsl.fr). Original data were downloaded from Zenodo (see Source) by the OA-ICC data curator. In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2024) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2025-12-15.

description: Raw data acquired by position sensors on board RV Elisabeth Mann Borgese during expedition EMB358 were processed to receive a validated master track which can be used as reference of further expedition data. During EMB358 data from the motion reference unit exail Phins Gen.3, the Trimble SPS356 GPS receiver, the Furuno GP-170 and the Furuno GP-150 GPS receiver were used to calculate the mastertrack. Data were downloaded from DAVIS SHIP data base (https://dship.bsh.de) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report. Processed data are provided as a master track with 1 sec resolution derived from the position sensors' data selected by priority and a generalized track with a reduced set of the most significant positions of the master track.
