title: Meteor Expedition M148/2 EreBUS nutrient data from Benguela Upwelling System and Angola Gyre

description: Nutrient data are from Nisken Bottle samples collected and measured onboard Meteor Expedition 148/2 “EreBUS”. Concentrations of dissolved inorganic phosphate (PO4), nitrite (NO2), NOx (nitrate+nitrite), and dissolved silicate (Si) were measured with the QuAAtro39 autoanalyser (Seal Analytical) using the method based on Strickland and Parsons, 1972. OSIL Seawater Low-Nutrient Standards were employed as secondary standards to check primary standard calibrations. Nitrate values are the calculated difference between NOx and nitrite. To determine Minimal Quantifiable Limit (MQL) for NOx, nitrite, phosphate and silicate we examined the variability (standard deviation, σ) around OSIL low-nutrient seawater concentrations and set MQL = 0 + 3σ. Ammonium (NH4+) was measured shipboard using the ortho-Phthaldialdehyde (OPA) fluorescence method (Holmes et al. 1999). MQLs for the offshore stations were based on values that fell below zero after calculating the concentration based on the calibration curves established for each station. We used these values as true undetectable values, because the zero values established from the calibration curve blanks tended to be greater (i.e. they have residual OPA fluorescence). MQLs were established for each station based on the mean fluorescence of undetectable samples plus three times the standard deviation of those fluorescence values. Oxygen was measured on selected samples by Winkler titration for the purpose of calibrating the CTD O2 sensor data (not calibrated in this data set). Temperature, Salinity, Temperature and Dissolved Oxygen data are included for as reference bottle information and derive originally from Mohrholz, IOW data storage server :https://www.io-warnemuende.de/en_iowdb.html (Data publicly available after 20.07.2021).

title: Nutrient concentrations in sea ice during POLARSTERN cruise PS106/1 (ARK-XXXI/1.1)

description: Samples for nutrient concentrations in sea ice were collected during the Polarstern expedition PS106.1. The ice drift expedition took place between 4 - 15 June 2017, north of Svalbard (Macke and Flores, 2018). Sea ice cores were collected using a Kovacs Mark II 9cm drill ice corer. In all ice stations, the first ice core was used for in situ ice temperature measurements, and the second one for methane concentration, stable carbon isotopic signature of methane, bulk ice salinity and nutrient concentrations (Verdugo et al., 2021). Nutrient concentrations in bulk ice (nitrate+nitrite, phosphate, silicate, nitrite, and ammonia) were analyzed on a four channel SEAL Analytical nutrient AutoAnalyzer 3 (AA3, Grasshoff et al., 1983).

title: Analysis of porewater constituents in sediments collected in the Campeche Hydrocarbon Province in the Southern Gulf of Mexico in 2015

description: In the Campeche Hydrocarbon province in the southern Gulf of Mexico, large areas of the seafloor are rich in natural gas and highly viscous crude oil. To understand the influence of these hydrocarbons on porewater geochemistry, we cored sediments from specific sites by gravity coring, multicoring and push coring during Meteor Expedition M114-2 in March 2015. Onboard, we retrieved porewater from these samples by Rhizon sampling. In addition, some seawater samples were collected. In the home laboratory, we analyzed the subsamples for silicate, phosphate, ammonium, nitrate, nitrate using a multi-channel nutrient analyzer, for sulfate and chloride using an ion chromatograph, for sulfide using the diamine approach, and we analyzed the isotopic composition of dissolved inorganic carbon using a GasBench coupled to an isotope ratio mass spectrometer.

title: Seasonal SST reconstruction by the UK'37 proxy for the Younger Dryas-Holocene transition in sediments of the Cariaco Basin, sediment core MD03-2621

description: The UK'37 sea surface temperature (SST) proxy, based on the distribution of long-chain akenones, was measured via mass spectrometry imaging (MSI) at 100-µm resolution in a 60-cm section of the well-dated core MD03-2621 from the Cariaco Basin (10.6782, -64.9715). This section spans an age of ~ 11.9 to 11.2 kyr b2k and thus includes the Younger Dryas-Holocene transition. Proxy data from each micrometer-sized spot were assigned to the upwelling and non-upwelling season based on the color of the sediment in that spot. As a result, separate records for the upwelling and non-upwelling seasons could be obtained. In order to translate UK'37 values into SST, a correction factor to account for differences between MSI-based data and conventional UK'37 data was applied. SST was calculated with the BAYSPLINE model.

This section spans an age of ~ 11.9 to 11.2 kyr b2k and thus includes the Younger Dryas-Holocene transition. The resulting record provides insights into interannual variability during this most recent glacial to interglacial transition. In order to translate UK'37 values into SST, a correction factor to account for differences between MSI-based data and conventional UK'37 data was applied. SST was calculated with the BAYSPLINE model.

title: AQUAHEALTH: Physiochemical parameters and Vibrio spp. abundance in water samples gathered in the Adriatic Sea

description: The genus Vibrio includes &gt; 60 species that are autochthonous and ubiquitous aquatic microorganisms, members of the bacterial community in marine environments worldwide. Given their impact on human and animal health and the relative ease of their cultivation, Vibrio species have been well studied: the genus includes human and animal pathogens that have caused major diseases around the world (e.g. cholera or vibriosis). The dataset contains Vibrio spp. abundance and measurements of environmental parameters (temperature, salinity, total dissolved solids, pH, dissolved oxygen, total nitrogen, total phosphorus, total particulate matter, particulate organic matter and particulate inorganic matter), gathered at Mali Ston Bay in the Adriatic Sea. Water sampling was conducted at two locations: a floating cage fish farm (located near small island Maslinovac) and a control site (near island Pučenjak) at different depths (0.5 m, 5 m, 10 m and 18 m). The sampling period covers seasonal measurements between 2016 and 2019.

title: AqADAPT: Physicochemical parameters and Vibrio spp. abundance in water samples gathered in the Adriatic Sea

description: Vibrio spp. are naturally occurring aquatic bacteria, highly adaptive and freely associated with a variety of biotic and abiotic surfaces including water, sediment, fish, shellfish, algae, and zooplankton. Although Vibrio spp. comprise a minor portion of the total microbial population, they are one of the key constituents of aquatic heterotrophic bacterial groups. More than 140 described species from the genus Vibrio can have a strong biotic impact, and consequently pose severe health risks (e.g. Vibrio cholerae) and economic losses (vibriosis infection). The dataset AqADAPT contains Vibrio spp. abundance and measurements of physicochemical parameters of seawater (temperature, salinity, total dissolved solids, pH, dissolved oxygen, conductivity, transparency, total nitrogen, total phosphorus, total particulate matter, particulate organic matter, particulate inorganic matter, nitrogen dioxide, nitrate and ammonia) gathered from the Adriatic Sea. Water sampling was conducted with the Niskin bottle at different depths (0.5m, 6m, 12m and the sea bottom) near floating cage fish farms (Cres and Vrgada) and corresponding control locations. In situ measurements were determined using YSI ProDSS Multiparameter Digital Water Quality Meter. Vibrio spp. abundance from water samples was determined by counting the total number of visible colonies that exhibited relief from the plate surface from the Thiosulphate Citrate Bile Salt Sucrose (TCBS) (Difco™, BD) agar plates. The sampling period covers seasonal measurements between 2019 and 2021.
