title: Surface summer phytoplankton pigment concentrations measured by HPLC during the SANAE-56 cruise in the Atlantic Southern Ocean between December 2016 and February 2017

description: Surface phytoplankton photosynthetic pigment concentrations were collected during the logistical austral summer cruise SANAE-56 from December 2016 to February 2017 on board the SA Agulhas II in the Atlantic sector of the Southern Ocean. The cruise consisted of various legs that covered a transect between Cape Town and Antarctica (primarily on the zero meridian) and a transect between Antarctica and South Georgia crossing the Weddell Gyre and the South Sandwich Islands. Discrete seawater samples, for chlorophyll-a and accessory pigment analysis, were taken at relatively high (&lt;1 degree) resolution from the ship's underway supply system (5-6m water depth) to determine the surface phytoplankton community abundance and structure. Filtered samples were analysed by High-Performance Liquid Chromatography (HPLC) at Laboratoire d'Océanographie de Villefranche (LOV – CNRS) according to Ras et al. 2008 (doi:10.5194/bg-5-353-2008).

title: Benthic foraminifera abundances of sediment core LV76-21

description: Benthic foraminifera were studied in the core LV76-21 sediments sampled in 1 cm-thick slices. All the samples were dried, weighted, and wet sieved using a 63 μm sieve. The benthic foraminifera shells were picked and counted from the 63–250 μm sediment fraction. In total, 222 samples were analyzed at an average resolution of 2.5 cm (range 1–5 cm). Almost all the samples had enough microfossils for representative evaluation, except for intervals 365 cm, 398–408 cm, 435–440 cm, 444–465 cm, and 490–510 cm, where foraminifera were rare or absent. The total benthic foraminifera abundance (BFA) expressed as the number of shells per 1 g of dry sediment (shells x g^−1).

title: Stable oxygen isotope record of Cibicidoides spp. of sediment core LV76-21

description: Sediments for the δ18O of planktic and benthic foraminifera analysis from core LV76-21 were sampled from 1 cm-thick slices with step of 2–5 cm along the core length. Foraminifera shells were picked from the sediment fractions of 150-250 µm in the samples where they were available. The δ18O of planktic and benthic foraminifera were measured at Tongji University (China) and at the Far Eastern Geological Institute (Russia). Isotope measurements from Tongji University were provided using a Finnigan‐MAT 252 mass spectrometer. The results were validated against a Chinese national carbonate standard (GBW04405) and NBS‐19. The standard deviation is 0.07‰ for δ18O. The isotope measurements from the Far Eastern Geological Institute were analyzed using a Finnigan-MAT 253 mass spectrometer with modification of Velivetskaya et al. (2009) without preliminary roasting. The standard deviation for the δ18O values is ± 0.05‰. All the values are reported on the Pee Dee Belemnite (PDB) scale.

title: Shipboard ADCP current measurements (75 kHz) during RV Sarmiento de Gamboa cruise iMirabilis2, Leg1 in Cabo Verde

description: Leg 1 of research expedition iMirabilis2 took place from 31st of July to the 30th of August 2021 (Las Palmas de Gran Canaria - Las Palmas de Gran Canaria) onboard RV Sarmiento de Gamboa. A particular focus was the characterisation of the Cadamosto Seamount. Current velocity data were acquired using a dual RDI Ocean Surveyor 75 kHz (Broadband and Narrowband) Vessel Acoustic Doppler Current Profiler (VADCP). The acquisition was made with the software VmDAS 1.46 and the processing with the CODAS (available at: https://currents.soest.hawaii.edu). The post-processing included a patch heading correction to eliminate gaps in the data and a watertrack calibration for both the phase and the amplitude.

title: Pulsation rate of coral Xenia umbellata in a aquarium experiment

description: Pulsations were recorded every 7 days from one colony per tank on three polyps. A pulsation was defined as a full contraction cycle. Counts were taken for 30 seconds in the morning using a tally counter, with water flow pumps off to prevent interference. To minimise bias, the same observer recorded all counts. Pulsation rate (pulsations per minute) was calculated by doubling the count and averaging three replicates per colony. Xenia umbellata originates from the Red Sea.

title: Chlorophyll-a per algal cell of coral Xenia umbellata in a aquarium experiment

description: One colony per tank was randomly selected every 7 days and stored at -20°C. On analysis day, colonies were thawed, homogenised in 10 ml demineralised water, and the slurry volume was measured. 2ml of the slurry was aliquoted, centrifuged twice to separate algal cells from coral tissue, and resuspended in demineralised water. In a darkened room, pellets were resuspended in 2 ml of 90% acetone, vortexed, and stored at 4°C for 24 h. After centrifugation, samples were split into two 1 ml cuvettes and measured on a UV-Spectrophotometer (663 nm & 630 nm) against a calibration curve. Each subsample was measured three times, with readings normalised to slurry volume and Symbiodiniaceae cell count. Xenia umbellata originates from the Red Sea.

Only living individuals (indicated by pink stain) were included in the data set.

title: Electromagnetic induction measurements with the vertically oriented dipole of the CMD Mini Explorer (118 cm transmitter-receiver spacing) taken in the Ahr floodplain at Mayschoß, Rhineland-Palatinate (Germany)

description: Electromagnetic induction (EMI) was measured with a CMD-Mini Explorer and a CMD Explorer (both GF Instruments s.r.o., Brno, Czech Republic) in June 2022. We used the vertical dipole (VDP) at coil spacings of 0.32 m (VDP1, CMD Mini Explorer), 0.71 m (VDP2, CMD Mini Explorer), 1.18 m (VDP3, CMD Mini Explorer), 1.48 m (VDP4, CMD Explorer), 2.82 m (VDP5, CMD Explorer) and 4.49 m (VDP6, CMD Explorer). With the existing coil spacings, effective penetration depths of 0.5 m (VDP1), 1.0 m (VDP2) and 1.8 m (VDP3) for the CMD Mini Explorer and 2.2 m (VDP4), 4.2 m (VDP5) and 6.7 m (VDP6) for the CMD Explorer could be achieved. According to the manufacturer, 70 % of the signal originate from above these depths. The EMI sensors measured the apparent electrical conductivity (ECa, in mS/m). Measurements were taken by carrying the instrument about 0.2 m (CMD Mini Explorer) respectively 0.9 m (CMD Explorer) above the ground while being directly connected to Differential -GPS (Leica GPS1200) for positioning. The acquisition rate was five measurements per second. Data quality was checked by measuring a reference line before and after each measurement. The maximum offset of the EMI values between the two time points was 1.2 mS/m. A correction of the data was not necessary. We removed the reference lines and single outliers. In addition, two interference areas were removed from all EMI data sets. (1) a L-shapped area, running from north to the center and then to east, in which an underground power cable runs. (2) an area on the north-eastern part of the measurement area. Information on the location and extent of the removed interference areas can be found in the enclosed explanation of the EMI measurements.The data set contains the EMI data with an intercoil spacing of 1.18 m (VDP3, CMD Mini Explorer).
