title: KOSMOS 2018 Gran Canaria mesocosm study: prokaryotes

description: This dataset contains the results of the analysis of standing stocks and activity of prokaryotes during the KOSMOS mesocosm experiment carried out in the framework of the Ocean Artificial Upwelling project. The experiment was carried out in the autumn of 2018 in the oligotrophic waters off Gran Canaria. During the 39 days of experiment nutrient-rich deep water was added to the mesocosms in two modes (singular vs recurring additions), with four levels of intensity. Prokaryotic abundances and viability were quantified with a FACSCalibur flow cytometer (Becton-Dickinson). Prokaryotic activity (as protein synthesis) was assessed by means of BioOrthogonal Non-Canonical Amino acid Tagging (BONCAT), using a Zeiss Axio Imager.Z2m Epifluorescence Microscope (AxioCam MRm, Carl Zeiss MicroImaging). The aim of this dataset was to study the effect of different upwelling regimes on the prokaryotic communities and its potential implications for organic matter cycling.

title: Living (RB-stained) benthic foraminiferal fauna sampled along the French Mediterranean coast in 2015

description: The stations were sampled along the French Mediterranean coast in spring (March-April) 2015 onboard the RV Europe. Bottom sediment at 28 stations (11 to 64 m water depth) was sampled using a Reineck box-corer. Three replicates (“a”, “b”, “c”; different box-corer launches) were done at each station. Each box-corer was sub-cored with a 7.4 cm diameter tube. Only the first top centimetre was preserved in 96% ethanol and stained with 2 g/L Rose Bengal. At the laboratory, after minimum two weeks each sample was washed through four sieves of 63, 125, 150, and 500 µm mesh sizes. Living (stained) benthic foraminifera from the 125-150 µm and 150-500 µm were collected under stereomicroscope and preserved in micropaleontological slides. Taxonomical recognition was done to the species level. The presented data in the table indicate the raw densities of foraminifera sorted per sample. The exact volume of sampled sediment was measured for each sample. Some samples were treated with Sodium Polytungstate (SPT) to separate benthic foraminifera from the sediment. The SPT density is indicated for each treated sample.
description: These data were acquired thanks to Pierre Boissery and the funding from the Agence de l'Eau Rhône Méditerranée Corse. The sampling survey was possible thanks to the Ifremer, especially Bruno Andral, and the RV Europe crew members.

title: Data on nematode genus abundance and counts at LTER HAUSGARTEN from 2000 to 2009, 2010, 2014 and 2019

description: This dataset contains information on Arctic deep-sea nematode abundance calculated for 10 cm² of seafloor on genus level (time period 2000 to 2009), as well as counts (years 2010, 2014 and 2019). Sampling was carried out in the Arctic summer with a multiple corer (MUC) at the LTER HAUSGARTEN observatory at three stations in 2000 to 2009, 2014 and 2019 (HG-I, HG-IV, HG-VII), and at nine stations in 2010 (HG-I to HG-IX). From each MUC deployment, three replicate samples were taken from different MUC cores (10 cm diameter), and the top five centimetres of sediment from each replicate sample were subsampled with a syringe (2.2 cm diameter). All samples were fixed in formol (4 %) and rinsed over a 32 µm sieve. The metazoan meiofauna was extracted by centrifugation in colloidal silica. Morphological genus determination, body size measurements and image acquisition of the nematodes were performed under a light microscope equipped with a digital camera and associated software.

title: Recent epifaunal benthic foraminifera counts in surface sediment samples from the Southeast Pacific

description: This study developed a unified taxonomic classification system for recent epifaunal benthic foraminifera species collected from surface sediment samples along the Southeast Pacific margin, including Cibicidoides wuellerstorfi, C. lobatulus, C. cf. ungerianus, Planulina ariminensis, P. ornata, and P. limbata. Morphological characteristics of these epifaunal benthic foraminifera specimens, such as test shape, periphery, chamber inflation, elongation, suture curvature, and wall porosity, were measured between December 2022 and June 2023. Furthermore, variations in morphological features like planoconvex tests, proloculus size, suture curvature, and pore patterns were observed among these foraminifera. The surface sediment samples were collected off the coasts of Chile and Peru between 1962 and 2014, covering latitudes from 12.70°S to 44.09°S and water depths ranging from 24 to 3,267 m. The temporal coverage of the samples spans the Holocene, with a focus on the late Holocene and modern samples. These samples were collected using various gear devices, including a multicorer (Sonne 156, Sonne 211, Meteor 92), a box corer (BIAC072014), a Petersen grab (USNS Eltanin), and a gravity core (Sonne 161). Detailed morphological examinations of the specimens were conducted using TM4000Plus HITACHI SEM imaging and a Leica S8 APO stereomicroscope, complemented by manual illustrations. The unified taxonomic criteria will enhance the accuracy of foraminifera-based proxies, such as stable isotopes and morphological studies, which are vital for paleoceanographic reconstructions.

title: Seawater carbonate chemistry, mass, length and gene expression of Sepia officinalis during experiments, 2011

description: The specific transporters involved in maintenance of blood pH homeostasis in cephalopod molluscs have not been identified to date. Using in situ hybridization and immuno histochemical methods, we demonstrate that Na+/K+-ATPase (soNKA), a V-type H+-ATPase (soV-HA), and Na+/HCO3- cotransporter (soNBC) are co-localized in NKA-rich cells in the gills of Sepia officinalis. mRNA expression patterns of these transporters and selected metabolic genes were examined in response to moderately elevated seawater pCO2 (0.16 and 0.35 kPa) over a time-course of six weeks in different ontogenetic stages. The applied CO2 concentrations are relevant for ocean acidification scenarios projected for the coming decades. We determined strong expression changes in late stage embryos and hatchlings, with one to three log2-fold reductions in soNKA, soNBCe, socCAII and COX. In contrast, no hypercapnia induced changes in mRNA expression were observed in juveniles during both short- and long-term exposure. However a transiently increased demand of ion regulatory demand was evident during the initial acclimation reaction to elevated seawater pCO2. Gill Na+/K+-ATPase activity and protein concentration were increased by approximately 15% in during short (2-11 day), but not long term (42 day) exposure. Our findings support the hypothesis that the energy budget of adult cephalopods is not significantly compromised during long-term exposure to moderate environmental hypercapnia. However, the down regulation of ion-regulatory and metabolic genes in late stage embryos, taken together with a significant reduction in somatic growth, indicates that cephalopod early life stages are challenged by elevated seawater pCO2.
description: In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne and Gattuso, 2011) 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).

title: Freshwater ostracod abundance in different water bodies from a polygonal tundra landscape near the WWF station Kytalyk at the Berelekh River in the Indigirka lowland (NE Siberia) during summer 2011

description: Patterned ground of the polygonal tundra yields sensitive indicators of environmental and climate change. Polygon ponds, mires and cryosoils are typical components of Arctic Siberian wetlands underlain by permafrost. Field studies of recent environmental dynamics were carried out in the Indigirka lowland in summer 2011 and 2012. Using a multidisciplinary approach, several stages of polygonal systems were studied as modern tundra habitats in the surrounding of the WWF station Kytalyk at the Berelekh River, a tributary of the Indigirka River. The floral and faunal associations of the polygonal tundra landscape were described. Ecological, hydrological, meteorological, limnological and cryological features were analyzed in order to evaluate modern environmental conditions and their essential controlling parameters. A monitoring program was carried out to measure changes of air, water and ground temperatures as well as water conductivity, water level and soil moisture and to collect water, diatom, zooplankton, zoobenthos, tecamoebae, phytoplankton and ostracod samples. These data sets contain environmental field data, logger data, various ecological data, and analyses of sediments and water.This dataset comprises freshwater ostracod abundance data in different water bodies from a polygonal tundra landscape, near the WWF station Kytalyk at the Berelekh River.
