title: Relative abundance of benthic foraminifera from sediment core SHN-T394, Argentine continental shelf

description: Thirty-six sediment samples of approx. 10 cm^3 were taken.  The number of samples and the distance between consecutive samples vary among the sedimentary units described above due to their textural differences. Unit A (215-135 cm) were sampled every ~10 cm. Unit B (135-89 cm)  were sampled continuously every 2 cm. Unit C (89-10 cm) levels with abundant fine-grained matrix were selected. Unit D (the uppermost 10 cm) only one sample was taken. For each sample, 10 g of sediment was treated with hydrogen peroxide (H2O2{~}) 10% to remove organic matter, washed through 75 μm sieve, and dried at 40º C in a thermostatic oven. All foraminifera and ostracods from at least 2 g of dry sediment were picked and extrapolated to the whole pretreated sample to standardized abundance.

title: Genetic analysis of carbohydrate metabolism in Strongylocentrotus purpuratus larvae during laboratory experiments with different food treatments

description: Strongylocentrotus purpuratus (Stimpson 1857) originally collected in November 2022 from La Jolla, USA (Lat: 32.842674; Long: -117.257767) were held in flow-through tanks which were filled with water from Kiel Fjord adjusted to 31.5 psu in the Christian-Albrechts-Universität zu Kiel at 10 °C. For experimental characterization of carbohydrate digestion between September and November 2023 S. purpuratus larvae were generated by gently shaking adult males and females and held in climate chambers at 15°C and 31.5 psu up to 10 days under two different food conditions. For genetic analysis of carbohydrate metabolism RT-qPCR was conducted. In brief, mRNA of samples from nine different time points (2 days post fertilization (dpf) – 10 dpf, n=4) was isolated and reverse transcripted into cDNA. Primer pairs were designed through NCBI primer blast, specifically targeting exon junctions of the selected carbohydrates enzyme genes for which the mRNA sequence is accessible in the S. purpuratus genome database echinobase.org. Genes were selected based on transcription patterns of the genes during early development. Primer specificity was validated through standard PCR, confirming the amplification of a single, specific product within the anticipated size range. Gene expression utilized the ∆∆CT method, and levels were normalized to the stable housekeeping gene EF1a (SPU_000595).
description: The attached tables contain the data collected in laboratory experiments at the Christian Albrechts University, Kiel between September and November 2023. Larvae of cultured S. purpuratus were cultured for up to 10 days for the data collection. Several F1 generations were generated for the experiments, which were treated independently of each other. The larval test organisms were cultivated in climate chambers at principally 31.5 psu, 15.5 °C and pH 8.2. ----Experimental food treatments:* Low food: 500 cells Rhodomonas sp. used / ml total culture* High food: 8000 cells Rhodomonas sp. used / ml total culture

title: Enzymatic analysis of carbohydrate metabolism in Strongylocentrotus purpuratus larvae during laboratory experiments with different food treatments

For experimental characterization of carbohydrate digestion between September and November 2023 S. purpuratus larvae were generated by gently shaking adult males and females and held in climate chambers at 15°C and 31.5 psu up to 10 days under two different food conditions. Carbohydrate-degrading enzymatic activity against various substrates (starch, laminarin, cellulose, xylan, trehalose) was assessed using 3,5-dinitrosalicylic acid (DNS, Miller, 1959). The activities of degradation were quantified by measuring the rate of reducing sugar production resulting from the hydrolysis of soluble starch, carboxymethylcellulose sodium salt (medium viscosity), laminarin from Laminaria digitata, xylan and D-(+)-Trehalose dihydrate. For all reactions the amount of reducing sugar was determined spectrophotometrically at 540 nm with glucose as the standard (xylose for xylan characterization) by first determining the difference between positive reaction and negative controls for t₀ and t₁ and then determining the difference t₁ - t₀. Finally, this was set in relation to the amount of protein used and the reaction time, so that the results could be in pmol reducing sugars mg protein⁻¹ h⁻¹.

Health assessments and larval size were conducted by sampling two 10 ml water samples at 0, 3, 5, 7, 9 & 10 days larval age.

description: Samples were collected in the surface ocean of the South East Pacific Ocean in subtropical and sub-Antarctic water masses, above the Chatham Rise and at the entrance of the Cook Strait in well mixed water masses, creating distinct oligotrophic and eutrophic regimes, respectively. Regimes manifested in nutrient profiles, phytoplankton, and bacterial abundances, as well as in Chlorophyll a concentration, which are separated by size fractions.

description: The heat flux measurements presented in this report were made during expedition MSM69 on the German research vessel RV Maria S. Merian (November 14, 2017 to December 22, 2017). A total of 69 heat flux measurements (profile HF1760 to profile HF1767) were successfully carried out colocated with the iLAB reflexion seismic profile. The aim of the measurements was to investigate whether low-temperature hydrothermal fluids diffuse at the seafloor where the oceanic basement is not covered by sediments. While low heat flux measurements clearly show that cold seawater enters the subsurface, no diffuse leakage of hydrothermal fluids could be detected at any location.
