title: TALDICE high resolution measurements of d-excess for MIS 9.3

description: The data here described are presented in the submitted paper Response of the Wilkes Subglacial Basin Ice Sheet to Southern Ocean Warming During Late Pleistocene Interglacials by Crotti et al. This data set includes new high resolution measurements of d-excess, d18O and ssNa+ for the Antarctic TALDICE ice core (Latitude: -72.783330, Longitude: 159.066670, Elevation: 2315.0 m). The new data set covers the interglacials periods of MIS 5.5, MIS 7.5 and MIS 9.3 (1486 m depth - 1548 m depth). The data are drawn on the TALDICE deep1 chronology (Crotti et al. 2021). The d-excess (d = δD − 8 × δ18O) (permill) record covers the periods MIS 5.5 , MIS 7.5 and 9.3 MIS is at 5 cm resolution and spans the following age-depths intervals:• MIS 5.5. Between 1378.5 and 1421.65 m depth, 110-135 ka • MIS 7.5. Between 1521.85 and 1524.5 m depth, 243-248 ka • MIS 9.3. Between 1541.80 and 1547.90 m depth, 320-343 ka The d18O record (permill) covers the periods MIS 5.5 , MIS 7.5 and 9.3 MIS is at 5 cm resolution and spans the following age-depths intervals:• MIS 7.5. Between 1521.85 and 1524.5 m depth, 243-248 ka• MIS 9.3. Between 1541.80 and 1547.90 m depth, 320-343 ka The ssNa+ fluxes record covers the periods MIS 5.5 , MIS 7.5 and 9.3 MIS is at 8 cm resolution and pans the following age-depths intervals: • MIS 7.5. Between 1521.81 and 1524.54 m depth, 243-248 ka • MIS 9.3. Between 1541.73 and 1547.96 m depth, 320-343 ka The d18O and dD (non presented here) to calculate the d-excess were analysed in Italy (University of Venice) and France (LSCE) using the Cavity Ring Down Spectroscopy (CRDS) technique. Analyses were performed using a Picarro isotope water analyser (L2130-i version for both laboratories). The data were calibrated using a three-point linear calibration with three lab-standards that were themselves calibrated versus Standard Mean Ocean Water (SMOW). The average precision for the δ18O and δD measurements is 0.1 and 0.7 ‰, respectively. The concentrations of ssNa+ were measured on TALDICE ice samples at 8 cm resolution by classical ion chromatography on discrete samples collected using a melting device connected to an auto-sampler for the MIS 7.5 and MIS 9.3 whereas Continuous Flow Analysis (CFA) was applied for MIS 5.5 samples. The total deposition ssNa+ flux was calculated multiplying the measured ice concentration of ssNa+ by the reconstructed accumulation rate. The accumulation rates were derived from the accumulation rates were obtained from the TALDICE deep1 age scale (Crotti et al. 2021).

title: KOSMOS laboratory experiment Bergen 2022 on ocean alkalinity enhancement: growth, survival, physiology and behaviour of Atlantic herring

description: Atlantic herring (Clupea harengus) during a laboratory experiment at the University of Bergen (Norway) in April/May 2022. This experiment was associated to the KOSMOS 2022 mesocosm campaign. Herring larvae were held in 6 rearing tanks until 37 days-post-hatch (dph). Ocean alkalinity enhancement (OAE) was applied 18 dph to half of the tanks. At several time points, growth (increase in standard length), basic physiology (routine metabolic rate) and behavior (swimming/hunting) were assessed by subsampling several larvae from each tank. At the end of the experiment, long-term survival was assessed by counting all larvae remaining in the tanks. Methodological details in Goldenberg et al. (under review).

title: High-frequency, year-round time series of the carbonate chemistry in a high-Arctic fjord (Svalbard) v2

description: The Arctic Ocean is subject to high rates of ocean warming and acidification, with critical implications for marine organisms as well as ecosystems and the services they provide. Carbonate system data in the Arctic realm are spotty in space and time and, until recently, there was no time-series station measuring the carbonate chemistry at high frequency in this region, particularly in coastal waters. We report here on the first high-frequency (1 h), multi-year (6 years) dataset of salinity, temperature, dissolved inorganic carbon, total alkalinity, CO2 partial pressure (pCO2) and pH at a coastal site (12 m) in Kongsfjorden, Svalbard. We show that the choice of formulations for calculating the dissociation constants of the carbonic acid remains unsettled, (2) the water column is generally somewhat stratified despite the shallow depth, (3) the saturation state of calcium carbonate is subject to large seasonal changes but never reaches undersaturation (Oa ranges between 1.4 and 3.0) and (4) pCO2 is lower than atmospheric CO2 at all seasons, making this site a sink for atmospheric CO2.

title: Fluorescent dissolved organic matter (FDOM) intensity (Parafac components and FDOM indices) in the surface water of the Mackenzie Delta Region during 4 expeditions from spring to fall in 2019

description: Fluorescent dissolved organic matter intensity was measured with an Aqualog®. Measurements were corrected for inner-filter effects and for the Raman and Rayleigh scattering (Murphy et al., 2013; doi:10.1039/C3AY41160E). The different fluorescent components of DOM were isolated from combined signal by PARAFAC modeling using the “drEEM Toolbox” and following the recommendation of Murphy et al. (2013; doi:10.1039/C3AY41160E). The DOM components derived from PARAFAC modeling were compared with PARAFAC components from other studies through the OpenFluor database (Murphy et al., 2014; doi:10.1039/C3AY41935E). The coble-peaks indicate major fluorescent components (Coble 1996; doi:10.1016/0304-4203(95)00062-3) in marine FDOM EEMs (Excitation-Emission-Matrix). Peaks T represents protein-like compounds (tyrosine and tryptophane), peaks A and C are indicators of humic-like components whereas peak M was associated to marine humic-like fluorescence. The fluorescence index (FI) is calculated as the ratio of fluorescence at emission 450 nm and 500 nm, at fixed excitation of 370 nm. The HIX index is the ratio of the areas of two spectral wavelength regions in the emission spectra for an excitation at 254 nm and it is obtained as: HIX = H∕L, where H is the area between 435 and 480 nm in the emission spectra and L is the area in the emission spectra between 300 and 345 nm (Zsolnay et al., 1999; doi:10.1016/S0045-6535(98)00166-0). The BIX index is obtained by calculating the ratio of the emission at 380 and 430 nm, excited at 310 nm: BIX = IEm380∕IEm430 (Huguet et al., 2009; doi:10.1016/j.orggeochem.2009.03.002).

title: KOSMOS 2018 Gran Canaria mesocosm study: water column biogeochemistry

description: The data set compiles biogeochemical water column collected during a KOSMOS mesocosm experiment carried out in the frame work of the Ocean Artificial Upwelling project. The experiment was performed in the North-East Atlantic Ocean off the coast of Gran Canaria in autumn 2018 and lasted for 39 days. In this study we investigated the effect of different intensities of artificial upwelling combined with two upwelling modes (recurring additions versus one singular addition) on POC export and its potential transfer efficiency to depth. The data set includes the amounts of surface water that were exchanged with nutrient-rich deep water (from ~300 m depth), primary production and chlorophyll a, elemental composition of suspended particulate matter (POC, PON, C:N) and prokaryotic heterotrophic production.

title: Flow cytometric assessment of virus-like particle, prokaryote and small phototrophic eukaryote abundances from sea foam, surface microlayer, 1-m depth, rainwater from the Swedish Skagerrak (Feb 2020)

description: Flow cytometry samples for analysis of virus-like particle, prokaryote and small phototrophic eukaryote abundances were collected from sea foam, surface microlayer and 1-m deep water from the Swedish Skagerrak during a 1-month campaign at Tjärnö Marine Laboratory in February 2020. Using a small boat, foam and microlayer were collected using a glass plate sampler, and 1-m deep water using a syringe connected to a hose. In addition, rainwater for flow cytometry was collected close to the coast in Duran bottles. Samples were fixed with glutardialdehyde (1% final concentration, Merck, Sweden), stored for 1 hour in the dark and subsequently stored at -80 °C. The purpose of the cellular and viral abundance assessment was to complement metagenomic analyses to investigate viral dispersal across the air-sea interface and along the natural water cycle. In addition, metadata for light conditions, wind speed, salinity, and temperature were recorded. For further details on the campaign and flow cytometric analysis, please refer to Rahlff et al., 2022.

title: Environmental data and image area measurements of different substrate types extracted from video transects recorded in the Logachev cold-water coral mound province

description: This dataset contains the percentage coverage of different substrate types (live scleractinian corals, dead scleractinian framework, rubble, hard substrates and fine sediments) found at the Logachev cold-water coral carbonate mounds. Video transect data were collected using the remotely operated vehicle (ROV) Holland-1 during the Changing Oceans Expedition 2012 on RRS James Cook (Cruise JC073) from 2012-05-27 to 2012-06-06. Image frames were extracted from the ROV videos and the percentage coverage was measured in Adobe Photoshop software (van der Kaaden and De Clippele, 2021). Terrain variables (i.e. Depth, Slope, Rugosity, Bathymetric Positioning Index) and Particulate organic matter (POM) per image file were extracted using the ESRI ArcMap v10.1 software. This data was used by De Clippele et al. (2021) to calculate biomass and to estimate the carbon and nitrogen turnover capacity of the study area.

title: KOSMOS 2018 Gran Canaria mesocosm study on artificial upwelling: pigment concentration and pigment-based phytoplankton community composition

description: Pigment concentration and pigment-based phytoplankton community composition data from a KOSMOS mesocosm experiment carried out in the frame work of the Ocean Artificial Upwelling project. The experiment was performed in the North-East Atlantic Ocean off the coast of Gran Canaria in autumn 2018 and lasted for 39 days. In this study we investigated the effect of different intensities of artificial upwelling combined with two upwelling modes (recurring additions versus one singular addition) on the phytoplankton community. Filters were analysed for a range of photosynthetic pigments using reverse-phase high-performance liquid chromatography (HPLC). Based on pigment concentrations, phytoplankton community composition was approximated using the CHEMTAX software with the original pigment ratios from Mackey et al (1996, doi:10.3354/meps144265). The input included Chl a, b, c2, and c3, peridinin, 19'-butanoyloxyfucoxanthin, fucoxanthin, neoxanthin, prasinoxanthin, violaxanthin, 19'-hexanoyloxyfucoxanthin, alloxanthin, diadinoxanthin, diatoxanthin and zeaxanthin. Divinyl Chl a was instead fully associated with Prochlorophyceae. The presence of the main phytoplankton groups is expressed in Chl a equivalents.

title: Details of direct shear experiments on powdered gouge of ash and scoria samples from Anak Krakatau, Sunda Strait, Indonesia (Table 1)

description: We performed laboratory friction experiments on simulated fault gouges of ash and scoria samples from Anak Krakatau (Sunda Strait, Indonesia), representing the two main lithologies that can be found at Anak Krakatau and measured the velocity-dependence of friction in velocity-step tests. Moreover, we have directly measured cohesion on the samples of powdered gouge of ash and scoria. The experiments were carried out using a single-direct shear device at room temperature. For the shearing tests, all samples were crushed and sieved to a grain size &lt; 125 µm. The ash sample was tested under fluid-saturated conditions (3.5 % NaCl brine) and the scoria sample was tested under fluid-saturated (3.5 % NaCl brine) and room dry conditions. The experiments were carried out at two different effective normal loads, 2.5 and 8 MPa, to simulate different depths of a proto shear plane within the volcanic edifice.

title: Wideband integrated bioaerosol sensor (WIBS) excited particle number concentrations measured in the Swiss container during MOSAiC 2019/2020

description: These datasets contain the total particle number concentrations of excited particles of sizes 0.5 to 20 μm (optical diameter). The WIBS measures the size, asymmetry and fluorescence of particles with an optical diameter of 0.5 – 20 µm. Detected particles are excited by two UV flashlamps at wavelengths of 280 and 370 nm and their emitted fluorescence is measured by two photomultipliers with bandwidths of 310 - 400 nm, and 420 - 650 nm. The WIBS counts excited particles at a maximum frequency of 125 Hz, which corresponds to a maximum concentration of 2.5*104 particles/L with a sample flow of 0.3 L/min. Excited particles were classified as fluorescent if their fluorescent intensity exceeded the background intensity by three standard deviations (3σ) and as hyper-fluorescent if the fluorescent intensity exceeded the background intensity by 9σ. Excited particles with a lower fluorescent intensity were considered to be non-fluorescent. The background fluorescence was determined by measuring the fluorescent signal in the measurement chamber in absence of particles. Background measurements were performed every 26 h. The combination of two excitation wavelengths and two detector wavebands allows the classification of fluorescent particles into seven types: A, B, C, AB, AC, BC, and ABC (Perring et al. (2015); Savage et al. (2017)). For further information about the instrumental setup, refer to Heutte et al. (Submitted).
