title: Single-shell stable isotopes, weights, ages, Marine Isotope Stages (MIS), and preservation states of Cibicidoides spp. from ODP Holes 177-1089C and 177-1089D

description: This dataset contains single-shell stable isotope data (d18O and d13C), shell weights, ages, and preservation states of Cibicidoides shells spanning MIS 9-10 from ODP Site 1089 north of Agulhas Ridge (-40.936°N, 9.894°E, 4620 m water depth). Sediment samples were processed following standard procedures. From each &gt;63µm sediment sample, all specimens of the genera Cibicidoides and Uvigerina were picked from the &gt;150 µm size fraction. Using a binocular microscope, each individual Cibicidoides and Uvigerina specimen was critically evaluated for preservation quality. Details of the Foraminiferal Preservation Index (FPI) can be found in the corresponding publication. In short, an initial score (IS) of 5 is applied to an ideal specimen with clearly defined whorls, sutures, pores, and other surface features. A shell with an IS score of 3 usually contains enlarged pores and “smoothed” looking surface features, including sutures and surface ornamentation. An IS score of 4 is assigned to specimens with more subtly smoothed features, and/or slightly enlarged pores. From the IS3-5 value for a given specimen, deductions of 1-2 points are applied to generate its final score (FS). A deduction of 1 point is applied for either a missing or fractured chamber, and/or evidence of slight dissolution. A deduction of 2 points is applied for extensive missing or fractured chambers, and/or evidence of extensive dissolution. For example, an assigned FS1 value for a specimen could be the result of highly smoothed surface features, with some combination of extensive dissolution pockmarks and/or one to several fractured/missing chambers (i.e. IS3 – 2 = FS1). The letter “A” assigned to the final score indicates that the appearance of the shell is glassy, “B” is assigned to pseudo-glassy shells, and “C” to frosty specimens. Specimens of varying preservation quality were purposely chosen for single-shell stable isotope analyses. Each specimen was weighed, and shells featuring narrow mass ranges were selected for individual analytical runs of d18O and d13C which allows for the optimization of instrument tuning. Single Cibicidoides shells were analyzed on a Thermo Delta V Kiel IV dual inlet mass spectrometer at the Lamont-Doherty Earth Observatory, and were corrected relative to the NBS-19 calcite standard. Average precision on these analyses was better than 0.08‰ for δ18O and better than 0.06‰ for δ13C. The age model is based on the published stable isotope record (Hodell et al. 2001) tuned to the deep sea benthic d18O stack (Lisiecki and Raymo, 2005; Ahn et al., 2017).

title: Size, age and otolith morphometrics of Benthosema glaciale collected during IESSNS south of Iceland in July 2020

description: This dataset contains biological measurements and the estimated age of 89 individuals of the North Atlantic myctophid Benthosema glaciale (glacier lantern fish). Individuals were collected opportunistically as bycatch in pelagic trawls (surface and deep) during the Icelandic portion of the International Ecosystem Summer Survey of Nordic Seas (IESSNS) conducted in south Icelandic waters and the Irminger Sea in July 2020. Frozen samples were processed on land in 2022 from five trawl stations located in three IESSNS strata regions (6,11, and 12). Further details on the trawl methodology, sampling and associated environmental variables can be found in related to references and the survey report (Ólafsdóttir and Kennedy, 2020). Observations include multiple length and weight measurements, as well as otolith morphometrics, including otolith length, width and area. Otoliths were photographed on a matte background, proximal side down, and the left otoliths were measured using ImageJ software (if only the right otolith was present, this was used). To age the fish using otoliths, annual rings were counted by two independent readers. If there were inconsistencies in age between them, both readers would confer to reach an agreement, or the otolith was not included in the analysis. The data is provided by the Marine and Freshwater Research Institute (MFRI) in Iceland.

title: Trawl records of krill (Meganyctiphanes norvegica) and glass shrimps (Pasiphaea sp.) in the inner Oslofjord between February 2020 and April 2023

description: An Isaacs-Kidd Midtwater Trawl (IKMT) with 2.5 m depressor and ca. 7 m2 opening and a 100 m2 pelagic trawl were used for sampling krill and glass shrimps in the inner Oslofjord between February 2020 and April 2023. Both gears had decreasing mesh sizes towards the cod end (IKMT: 3.5 cm to 1 cm, 4 mm cod end liner with 1 mm cod end bucket; pelagic trawl: from ca 20 cm to 1 cm, 3 mm cod end liner), and neither provides quantitative catches. The catch data was used for characterizing acoustic targets and relative comparisons between depths, seasons, and stations. Sampling depths were determined based on hull-mounted Simrad EK500 echosounder recordings to sample above, within and partly below krill scattering layers. The sampling depth was monitored by a ScanMar depth sensor. Towing speed was 2.8- 3 knots and tows lasted ~15 min. Trawl samples were sorted upon retrieval and the volume of the krill catch determined. Krill (Meganyctiphanes norvegica) and glass shrimps (Pasiphaea sp.) were frozen separately and, for subsamples of up to 50 specimens, length and partly wet weight determined (i.e. individual krill/glass shrimps were measured with a scale in the laboratory after thawing). Length was measured from the tip of the rostrum to the end of the telson. In some cases, the rostrum of the animals was damaged, and then the distance from the eye to the end of the telson was measured. Both methods were applied in one sample, and the resulting regression slope coefficient (slope = 1.07) can be used to correct the measurements from individuals with broken rostrums. The dataset includes in total 43 catches from 2 stations and 13 dates and measurements of 2253 krill and 425 glass shrimps.

description: This dataset contains biological measurements of 338 individuals of the North Atlantic myctophid Notoscopelus kroyeri (Krøyer's lantern fish). Individuals were collected opportunistically as bycatch in pelagic trawls (surface and deep) during the Icelandic portion of the International Ecosystem Summer Survey of Nordic Seas (IESSNS) conducted in south Icelandic waters and the Irminger Sea in July 2020 and south and west Icelandic waters in 2021. Frozen samples were processed on land in 2022 from twelve trawl stations located in four IESSNS strata regions (5, 6,11, and 12). Further details on the trawl methodology, sampling and associated environmental variables can be found in related to references and two survey reports (Ólafsdóttir and Kennedy 2020, Ólafsdóttir et al. 2022).

title: Bulk density from the Jena Experiment (Main Experiment, year 2004)

description: This data set contains measurements of soil bulk density in different depth layers. Data presented here is from the Main Experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained in general by bi-annual weeding and mowing. Since 2010, plot size was reduced to 5 x 6 m and plots were weeded three times per year.Soil bulk density was determined in spring from undisturbed soil samples to a depth of 30 cm. Three soil cores per plot were taken with a split tube sampler with an inner diameter of 4.8 cm and separated in depth increments of five cm. The bulk material was passed through a sieve with 2 mm mesh size, dried to constant weight at 40 °C and subsequently weighed to calculate the density.Paired sampling was chosen to avoid additional spatial variability (Lal et al., 2000), which means that three of the five sampling locations of 2002 bulk density measurement, that were in the core area of the plots, were chosen for the repeated sampling. The spatial distance of the paired soil samples were less than 30 cm.
description: The main experiment on the field site of the Jena Experiment comprises a split-plot design in which additional treatments (e.g. no weeding allowing for invasion of other species, or application of fertilizer) have been applied to subplots along the outer margin of the plots (see Treatment description in the section "further details"). While in this dataset only data from the core area (mown and weeding of all none-sown species twice a year, no additional treatments) is reported, all potential treatments are listed as the first parameters in the data file to guarantee compatibility with other datasets that include different treatments. There are two types of missing values contained in the dataset. Empty cells represent missing values that result from the design of the experiment when the respective value does not occur and could thus not be measured. For example, in the columns of species-specific biomass cells are left blank, when the species was not sown into the respective plot. Missing values that resulted from methodological problems, sampling errors, or lost samples/data are marked with "-9999".This dataset is part of a collection of measurements of physical and chemical soil properties in the Jena Experiment. Similar data from other experiments (e.g. Main Experiment, Dominance Experiment; see details above), other years, or other methods quantifying related data might be available (https://doi.pangaea.de/10.1594/PANGAEA.885439).

title: Stomatal conductance, leaf greenness, and height of species in the Jena-Ecotron experiment

description: This dataset contains stomatal conductance, leaf greenness, and height of species in the Jena-Ecotron Experiment in 2012. This experiment was conducted in the Montpellier European Ecotron (CNRS, France), an advanced controlled environment facility for ecosystem research, and aimed at understanding the impact of plant species richness (4 vs. 16 species) for ecosystem carbon and water fluxes.The soil monoliths used in this experiment contained plant communities originating from the long- term Jena Experiment (50°57.1' N, 11°37.5' E, 130 m above sea level; mean annual temperature 9.3°C, mean annual precipitation 587 mm) established in May 2002. Twelve plots were selected for the Jena-Ecotron study according to the following criteria: (1) the four functional groups grasses, legumes, small and tall herbs were present, (2) realized species numbers were close to sown species richness, and (3) plots were equally distributed across the experimental field site to account for different soil textures. Large monoliths (2 m² surface area, diameter of 1.6 m, 2 m depth with a weight of 7 to 8 tons) including intact soil and vegetation were excavated in December 2011 and placed in lysimeters. In March 2012, before the start of the vegetation growth, the lysimeters were transported and installed in the Macrocosms platform of the Montpellier European Ecotron.Stomatal conductance (gs, mmol/m²/s) was measured with a portable leaf porometer (SC-1 Leaf porometer, Decagon Devices, Pullman, USA). Measurements were done in the auto mode using the first 30 s of stomatal conductance data to predict the final stomatal conductance under true steady state conditions. Leaf greenness (SPAD; unitless), an estimate of chlorophyll concentrations, was obtained by measuring the absorption of two different wavelength (650 nm and 940 nm) with a portable chlorophyll meter (SPAD-502; Konica-Minolta, Osaka, Japan). The growth height of three shoots (Ind h; cm) per species and unit was measured with a ruler. Values of stomatal conductance, leaf greenness and growth height of the individual measurements were averaged per species per plot.
description: There are two types of missing values contained in datasets from the Jena Experiment. Empty cells represent missing values that result from the design of the experiment. Empty cells result when the respective value does not occur in the design and could thus not be measured. For example, in the case of species-specific biomass cells are left blank, when the species was not sown in the respective plot. Missing values that resulted from methodological problems, sampling errors, or lost samples/data are marked with "-9999".This dataset is part of a collection of measurements of the Jena-Ecotron Experiment, which was part of the Jena Experiment.

title: Seawater carbonate chemistry and shell morphometrics during CO2 acidified seawater laboratory experiment and field experiment of flat tree oysters, Isognomon alatus (Gmelin, 1791)

description: Seawater changing chemistry has consequences on coastal ecosystems and their living resources. Future projections suggest the pH could drop 0.2-0.3 pH units by the year 2100 under a business-as-usual (BAU) CO2 emission scenario. Marine calcifying organisms such as corals, calcifying algae, crustaceans, mussels, oysters and clams are most likely to be impacted by ocean acidification. The Isognomon alatus (flat tree oyster) is an important species that can be negatively affected by the lowering of seawater pH. Isognomon alatus is an important food source, a substrate for other benthic organisms (e.g., stone crab, Menippe mercenaria) and contribute to nutrients recycling in coastal ecosystems. The study was conducted to test the impacts acidified seawater CO2 on the growth of I. alatus under controlled laboratory conditions as well as field experiment. The Isognomon alatus lost weight and experienced negative growth rates of –0.56 +- 0.36 mg /g/day under average pH values of 7.8 expected by the end of this century compared to a loss of –0.26 +- 0.23 mg/g/day under ambient pH (value 8.1) conditions. In contrast, I. alatus incubated in a field experiment showed a gain in weight and positive growth of 3.30 +- 0.23 mg/g/day despite exposure to pH levels (7.4) during low tide significantly lower than those experienced in the laboratory. Overall, the results showed concern on the impacts of acidification flat tree oyster (Bivalvia:Isognomonidae). A decline of calcifying bivalves populations can impact coastal ecosystems function and indirectly affect the human beings that depend on them as a food source.
description: In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2021) 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 2021-07-15.

title: Chemical and physical data of tar balls and biological characteristics of rafting organisms from the landfall event on tropical sandy beaches (~8S) of northeastern coast of Brazil in 2022

description: As the demand for production and transportation of marine oil increases worldwide, oil spills from a variety of sources have occurred repeatedly in recent decades. These spills lead to the formation of tar balls, the final stage of residual oil, which, as other floating materials, can act as substrates for colonization by marine organisms, including goose barnacles and polychaeta. The dispersal of these tar balls in the ocean gives rise to several ecological consequences and societal impacts, such as chemical contamination, the introduction of non-indigenous species, loss of biodiversity and ecosystem services, and significant economic implications, particularly affecting coastal communities that depend on fishing and tourism. To comprehend the role of tar balls in coastal pollution and to develop effective tools for environmental monitoring and management, it is essential to employ biological and chemical methods of analysis. These datasets contain physical (length, width, volume, and weight) and chemical (aliphatic and polycyclic aromatic hydrocarbon analysis based on Wang et al., 1999 and Albaigés et al., 2015) data of the interior and surface of 37 tar balls. Additionally, it includes biological data (taxonomic identification, capitulum length, width, weight, and maturation stage) of 413 rafting organisms found attached to tar balls. The manual collection of tar balls colonized by these rafting organisms was conducted during the event of landfall on the tropical sandy beaches (~8S) of the northeastern coast of Brazil in August and September 2022 (Bérgamo et al., 2023). The analyses were performed at the Benthos Laboratory and the Organic Compounds in Coastal and Marine Ecosystems Laboratory, both part of the Department of Oceanography at the Federal University of Pernambuco, Brazil.
