title: Continuous corrected particle number concentration data in 10 sec resolution, measured in the Swiss aerosol container during MOSAiC 2019/2020

description: This dataset contains corrected particle number concentration data measured during the year long MOSAiC expedition from October 2019 to September 2020. The measurement was performed in the Swiss aerosol container on the D-deck of Research Vessel Polarstern using an inlet with an upper cut-off of 1 µm (called also interstitial inlet). Data were collected by a Condensation Particle Counter (CPC) model 3025 (TSI Inc.) in 10 s resolution with a lower cut-off diameter of 3 nm. More detailed information about its position and the measurement setup can be found in (Beck et al., 2022). The data are cleaned from calibration and zero-check filter periods and the time-stamps of all data points was synchronized to its closest 10 s interval. Some periods of the measurements were corrected for a step in the signal (see file description).Participation of the Swiss Container was co-financed by the Swiss Polar Institute and University of Helsinki.
description: Some periods of the measurements were affected by repeated step changes in the particle number concentrations. This was caused by a valve, which was positioned in the line behind (downstream) the CPC and switched between a total air inlet and an interstitial inlet. During odd hours (i.e. 1 am, 3 am etc.) the valve was open to the interstitial inlet, during even hours to the total inlet. During the affected periods (less than ten periods with a duration of less than 12 hours, except for a three-day period from Dec. 08, 2019 to Dec. 10, 2019), the measured particle number concentrations behind the interstitial inlet are lower compared to the previous and the following hour behind the total inlet. To correct for these step changes in concentration, we calculated two correction factors, i.e. at the beginning and at the end of the affected period. The two correction factors are derived by dividing the median particle number concentrations of 3 minutes before (after) the start (end) of the affected period by the median particle number concentration of 3 minutes after (before) the start (end) of the affected period. Each data point of the affected period was then corrected by multiplying its particle number concentration by the linearly interpolated correction factor at the corresponding timestamp. The corrected data set may still contain minor artefacts related to the step change correction, i.e. small deviations of the number concentration in the order of &lt; 10 %. The counting uncertainty of a CPC is nominally 10 %. Depending on how the dataset is used this might be relevant or not. The dataset has a time resolution of 10 sec. More detailed information about the measurement setup can be found in (Beck et al., in prep.). The data columns include Time, Latitude, Longitude, Particle number concentration and a correction flag (0=uncorrected, 1 = corrected).We used 10 sec time resolution positional data from the following datasets: Rex, M (2020), Haas, C (2020), Kanzow, T (2020), Rex, M (2021a,b).

title: Seawater carbonate chemistry and antioxidant defences, oxidative stress of two marine copepods

description: We collected samples for oxidative stress and antioxidants in a high CO2 mesocosm experiment for two weeks, focussing on two common crustacean copepods Calanus finmarchicus and Temora longicornis. The samples were collected during a field experiment campaign studying responses of plankton communities to future ocean acidification (OA), off the Norwegian coast south of Bergen. The main results showed that there were species-specific differences between Temora and Calanus, especially in antioxidant defences (glutathione system) and oxidative stress (lipid peroxidation and reduced:oxidised glutathione ratio). Regular monitoring of chlorophyll a and jellyfish abundances taking place during the field campaign revealed that both chl a and predators may have affected the eco-physiological response. Antioxidant and oxidative stress levels are known to respond sensitively to both the food quality and quantity and the predator pressure, apart from environmental (i.e., abiotic) changes. Calanus was more robust towards OA, perhaps due to its high tolerance to a wide range of vertical physical-chemical conditions. Both top-down and bottom-up factors seem to play a role for the outcome of copepod responses to future ocean acidification.
description: In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2020) 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 2021-01-25.

title: Mg/Ca ratio of planktonic Orbulina universa from Green Island, Taiwan (0-50 m depth)

description: Mg/Ca anlaysis of foraminiferal calcite shells. Foraminifera obtained from sediments (benthic, Uvigerina spp.; sediment from ODP Site 1015, California Margin) and from plankton tows (planktonic, Orbulina universa, plankton tow specimens were collected near Green Island, Taiwan in May 2019 using a 1 m plankton net Sea-Gear, 150 µm mesh, 0-50 m depth), were analyzed. Mg/Ca were obtained applying Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and wavelength-dispersive X-Ray Spectroscopy by electron probe microanalyzer (EPMA). The goal is to assess the use of EPMA as an alternative technique for Mg/Ca analyses of foraminiferal calcite shells.

title: Ambient concentrations of aerosol precursor vapor concentrations (sulfuric acid, methanesulfonic acid, and iodic acid) in 5-minute resolution measured by a nitrate chemical ionization mass spectrometer

description: This dataset contains ambient concentrations of aerosol precursor vapors measured in the central Arctic during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. The timeseries includes a full year of sulfuric acid (SA), methanesulfonic acid (MSA), and iodic acid (IA) concentrations retrieved at a time resolution of 5 minutes between October 2019 and September 2020. The data were collected using a nitrate chemical ionization mass spectrometer (NO3-CIMS) as described by Jokinen et al. (2012). The instrument was located in the Swiss container, which was placed on the starboard side of Polarstern's bow on the D-deck during the campaign (Shupe et al., 2022). The concentration retrievals were obtained by integrating peaks from the high-resolution mass spectra for each compound of interest (either as a deprotonated ion or as its corresponding cluster with nitrate), normalizing the result with the sum of charger ions (NO3-, HNO3NO3-, (HNO3)2NO3-), and multiplying by the calibration factor (6×109 molec·cm-3) obtained from a dedicated calibration using SA. Since the instrument calibration was only performed using SA, the concentrations of MSA and IA are low limit estimations. SA was determined by peaks at mass to charge ratios (m/z) of 96.9601 Th (HSO4-) and 159.9557 Th (H2SO4NO3-), MSA was determined by m/z peaks at 94.9808 Th (CH3SO3-) and 157.9765 Th (CH3SO3HNO3-), and IA was determined by m/z peaks at 174.8898 Th (IO3-) and 237.8854 Th (HIO3NO3-). Zero measurements were performed periodically by placing a filter on the inlet of the instrument to determine the detection limit for each individual species. The detection limits were calculated as μ + 3 × σ, where µ is the average concentration and σ is the standard deviation, both of which were evaluated during filter measurements. The resulting detection limits are 8.8e4, 1.5e5, and 5.5e4 molec·cm-3 for SA, MSA, and IA, respectively. The dataset includes flags to specify the data that are below the detection limit. The influence of local pollution from the research vessel and other logistic activities was identified by applying a pollution detection algorithm (Beck et al., 2022) to particle number concentrations from a condensation particle counter (CPC3025, TSI) that was also located in the Swiss container. Periods that were potentially affected by primary pollution are flagged in the dataset. The columns in the data file include the date and time in Coordinated Universal Time (UTC); the concentration of SA, MSA, and IA in molec·cm-3; a detection limit flag for each individual species (1 = below detection limit); and a local pollution flag where the data may have influence from the vessel and logistical activities (1 = pollution was detected).

title: Analyses on Cibicidoides wuellerstorfi from ODP Hole 165-999A

description: For trace element analyses, single specimens of C. wuellerstorfi have been analyzed using femtosecond laser ablation inductively coupled plasma mass spectrometry (fs-LA-ICP131 MS) at the Geochemistry Laboratory at the Max Planck Institute for Chemistry. Na, Mg, and Sr of 142 specimens of C. wuellerstorfi have been measured at high-resolution on (up to) each of the final five chambers to eliminate possible inaccuracies that are likely to be caused by varying sample size. The fs-LA-ICP-MS analyses were performed on 25-μm diameter spots on each chamber with a pulse repetition rate of 15 Hz at low fluence (0.1-0.3 J/cm2). Calibration was performed with the microanalytical synthetic reference material MACS‐3 for carbonate and NIST612 for silica. Average values of all chambers analyzed in the same specimen were used for further analyses. Since foraminifers from different regions show particular offsets in the Mg/Ca composition of their shell, depending on region specific temperature ranges of ambient seawater, region-specific formulas are used. We have applied the formula Mg/Ca=0.82e^0.19*BWT of Tisserand et al. (2013) from samples collected from similar geographic situations to avoid offsets. The formula has been applied to calculate temperature variability of each analyzed chamber. The average value obtained from chamber-to-chamber temperature variability of each specimen has been applied as average temperature data of the entire test.

title: Dataset: Percepção de consumidores e produtores sobre produtos agroecológicos e marcas coletivas em Alta Floresta/MT

description: O presente trabalho investigou a assimetria de informação no mercado de produtos agroecológicos, identificando a dificuldade de consumidores em distinguir atributos de credibilidade e o desafio de produtores em comunicar o valor imaterial de sua produção. O objetivo principal consistiu em compreender como a marca coletiva, estruturada sob a ótica do place branding, poderia atuar como sinal redutor dessa assimetria, tomando como estudo de caso a Associação Guadalupe Agroecológica (AGuA), em Alta Floresta, Mato Grosso. Metodologicamente, realizou-se uma pesquisa aplicada, de natureza qualitativa, que envolveu revisão bibliográfica, diagnóstico territorial e produtivo, levantamento de percepções de associados e consumidores, além da co-criação da identidade visual e normativa do signo distintivo. Os resultados do diagnóstico reforçaram a hipótese de existência de falhas de mercado decorrentes da falta de informação, validando a demanda por um sinal de confiança territorial. O estudo sugeriu que a marca coletiva se apresenta como o instrumento mais adequado à realidade da associação, permitindo abrigar uma cesta diversificada de produtos e serviços, diferentemente das limitações impostas por indicações geográficas ou certificações convencionais. Como produto tecnológico, foram estruturados o regulamento de utilização e a identidade visual da marca, culminando no depósito de nove pedidos de registro junto ao Instituto Nacional da Propriedade Industrial (INPI), abrangendo desde alimentos e cosméticos até serviços de turismo e educação. Concluiu-se que a marca coletiva, gerida como ativo territorial, constitui uma tecnologia social viável para agregar valor à agricultura familiar, fortalecer a governança local e reduzir a incerteza nas transações comerciais.

title: Chemical composition and snow physical properties of 35 profiles in a snow trench at Dome C, East Antarctica (2019)

description: The data set provides the chemical composition and physical snow properties of a 50m long and 1.5m deep snow trench sampled at Concordia Station (Dome C) in December 2019. The chemistry data includes 35 profiles of concentration of anions (SO42− ,NO2^− , NO3− , MSA, Cl−, Br−, oxalate, F−, acetate and formate) and cations (Li+, Na+, NH4+ , K+, Mg2+, and Ca2+). 31 profiles where sampled at 3 cm resolution and 4 profiles are sampled at 1.5 cm resolution. The measurements were carried out at Institut des Geosciences de l’Environnement (IGE), Grenoble and Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung, Bremerhaven. Throughout the files, trench snow pits are labeled by the letter "P" followed by their horizontal distance in meters to the left-most profile of the trench, from P0 to P50.

The physical properties include 33 snow density and specific surface area (SSA) profiles and 201 Snow Micro Pen (SMP) measurements (Schneebeli et al., 1999) to estimate snow hardness. SSA was measured at 3 cm resolution using ASSSAP (Arnaud et al., 2011, Libois et al. (2014). Snow density was measured at 3 cm resolution using a scale and squared metal sampler tool with a known volume. SSA and density were measured along the same profiles as chemistry, except for P0.3 and P47.7 who share the same SSA and density profiles as P0 and P48, respectively. SMP measurements were realized every 25 cm along the trench (201 profiles). The vertical resolution is extremely fine (0.004 mm) but the measurements were averaged at 1 cm resolution to obtain a macroscopic significance. The snow hardness probe was set to penetrate up to 150 cm, but it stopped earlier for several profiles due to too hard layers, leaving a few incomplete profiles.
