title: NortheastChinaSoybeanYield20m: an annual soybean yield dataset at 20 m in Northeast China from 2019 to 2023

description: Accurate monitoring of crop yield is important for ensuring food security. Current yield estimation methods, such as machine learning models or the assimilation of remotely sensed biophysical variables into crop growth models, depend heavily on ground observations and involve significant computational costs. To solve these problems, a hybrid framework coupling the World Food Studies Simulation Model (WOFOST) and the Gated Recurrent Unit model (GRU) was proposed for soybean yield estimation in Northeast China from 2019 to 2023.

This dataset provides 20 m annual soybena yield in Northeast China from 2019 to 2023.

title: KOSMOS 2021 Gran Canaria mesocosm study on ocean alkalinity enhancement: metazoan zooplankton image-based carbon mass

description: This data was collected as a part of a mesocosm study to investigate the ecosystem impacts of ocean alkalinity enhancement, within the EU H2020 OceanNETs project. Nine mesocosms were deployed in Taliarte Harbour (Gran Canaria, Spain) and were regularly sampled using integrated water samplers between 10th September-25th October 2021. A gradient design was used in this experiment with a total of nine different alkalinity concentrations. Seawater alkalinity ranged between ambient (0 µeq kg-1 added alkalinity, OAE0) and 2400 µeq kg-1 additional alkalinity (OAE2400). The alkalinity levels increased in equal intervals of 300 µeq kg-1 across nine mesocosms (OAE0, OAE300, OAE600, OAE900, OAE1200, OAE1500, OAE1800, OAE2100, OAE2400). This data set contains image-based, biovolume-derived carbon mass (µgC per individual) of selected metazoan zooplankton taxa from these nine mesocosms. Here are included metazoan zooplankton image-based carbon mass measurements. C mass is calculated from biovolume, which was derived from length and width-based measurements (see Sanchez et al, in prep, for details on conversions). Metazoan zooplankton were sampled with apstein net (ø17cm, mesh size 55µm, 64.06285L) hauls taken every four days (except the first 11 days, when samples were only taken on days 1 and 11). Zooplankton were size fractioned and assessed in the correspondent size class (small: 55-200µm; medium: 200-500µm; large: 500µm-3mm). Only organisms in the medium and large size classes were photographed. The experiment, which lasted 33 days, was divided into four response phases (see Sánchez et al. (in prep)): i) pretreatment (days 1 to 4, treatment was implemented on day 4), ii) immediate (days 5-10), iii) shorter term (days 11-22), iv) longer term (days 23 to 33).
description: This data set is associated to the submission by Paul et al. (in review) (https://doi.pangaea.de/10.1594/PANGAEA.966941), so we refer to this data set for basic parameters like water temperature, salinity, pH and carbonate chemistry, to avoid repetition. It is also associated with the dataset "KOSMOS 2021 Gran Canaria mesocosm study on ocean alkalinity enhancement: metazoan zooplankton carbon biomass" (https://doi.pangaea.de/10.1594/PANGAEA.971764), which uses carbon mass conversion factors derived from it.

title: Seabed images taken at pilot oyster reefs in the Borkum Riffgrund marine protected area during Heincke HE601 cruise (June 2022)

description: Imagery transects with a camera attached to a frame design for taking pictures in a 50 x 50 cm area. Seabed images transects were carried out by scientific divers during the Heincke HE601 cruise focusing on developing and testing monitoring techniques at the Borkum Reef Ground and Sylt Outer Reef Marine Protected Areas. The camera used was a Canon EOS M6 camera, the pictures were taken perpendicularly to the seabed. The transects were done along a preset track across the reefs, number of pictures per transect varied based on diving time. The seabed images provide insights into the general composition of key species, higher systematic groups and ecological guilds. The images also contain valuable information on how benthic species are associated to each other. Transect files include individual images, whereas metadata of each image including diving depth, date/time, if the image was further analyzed, corresponding diver is found in a separate file. Geographical coordinates of individual images is unavailable.

title: Monte Carlo simulation results of zircon depletion effects on Hf isotopic compositions of dust

description: Combined Sr-Nd-Hf isotopic data of two reference materials (AGV-1/BCR2) and 50, 10 and 5 mg aliquots of carbonate-free fine grain (&lt;10 µm) separates of three loess samples (Central Europe/NUS, China/BEI, USA/JUD) are presented. Good agreement between measured and reference Sr-Nd-Hf isotopic compositions (ICs) demonstrate that robust isotopic ratios can be obtained from 5-10 mg size rock samples using the ion exchange/mass spectrometry techniques applied. While 87Sr/86Sr ratios of dust aluminosilicate fractions are affected by even small changes in pretreatments, Nd isotopic ratios are found to be insensitive to acid leaching, grain-size or weathering effects. However, the Nd isotopic tracer is sometimes inconclusive in dust source fingerprinting (BEI and NUS both close to epsilon-Nd(0) -10). Hafnium isotopic values (&lt;10 µm fractions) are homogenous for NUS, while highly variable for BEI. This heterogeneity and vertical arrays of Hf isotopic data suggest zircon depletion effects towards the clay fractions (&lt;2 µm). Monte Carlo simulations demonstrate that the Hf IC of the dust &lt;10 µm fraction is influenced by both the abundance of zircons present and maturity of crustal rocks supplying this heavy mineral, while the &lt;2 µm fraction is almost unaffected. Thus, epsilon-Hf(0) variations in the clay fraction are largely controlled by the Hf IC of clays/heavy minerals having high Lu/Hf and radiogenic 176Hf/177Hf IC. Future work should be focused on Hf IC of both the &lt;10 and &lt;2 µm fractions of dust from potential source areas to gain more insight into the origin of last glacial dust in Greenland ice cores.
description: Monte Carlo simulation were done in MATLAB to model zircon depletion effects on the Hf isotopic composition of hypothetical 5 mg amount of dust (&lt;10 and &lt;2 micron fractions). All simulation parameters as defined in the original publication.

title: Metadata and sampling record of Eurasian Jays from Hesse, Germany 2020/21

description: Eurasian Jays Garrulus glandarius (Corvidae, n = 16) were trapped in Caldern, Hesse, Central Germany in the years 2020 and 2021 to check for the presence of haemosporidian parasites. For this we collected metadata (e.g. collection date, sex, measurements) as well as feather, faeces and blood samples for subsequent analysis of haemosporidian parasites (Haemoproteus and Leucocytozoon). All individuals were infected with at least one haemosporidian genus. The most common infection pattern was a mixed infection with Haemoproteus and Leucocytozoon, whereas no Plasmodium infection was detected in any of the samples of the Jays.

title: Accumulation rates of biogenic components of ODP Hole 121-758A

description: The multi-proxies (BAR, bio-SiO2 MAR, and CaCO3 MAR) of productivity in Ocean Drilling Program (ODP) Leg 121 Site 758 Hole A (5°23.05'N, 90°21.67'E) during the late Miocene. Based on the biostratigraphic zones, we convert sediment depths to absolute ages on the Geologic Time Scale 2020 timescale (Gradstein et al., 2020; doi:10.1016/C2020-1-02369-3). We extract barite from marine sediments using the modified sequential leaching method (Eagle et al., 2003; doi:10.1029/2002PA000793; Paytan et al., 1993, doi:10.1038/366445a0) and examine the size and morphology of barite crystals by a scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX). We use the modified method after Mortlock et al. (1989, doi:10.1016/0198-0149(89)90092-7) and Lyle et al. (2019, doi:10.5194/cp-15-1715-2019) to extract biogenic opal from marine sediments. For the carbonate extraction, we digest sediments with 1.5 ml hydrofluoric acid and 0.5 ml concentrated nitric acid in a 50-ml Teflon tube at 180°C for 12 hours. After digestion, we evaporate all the acids on a 150°C electric heating plate. The sample reacts with 1 ml concentrated nitric acid and 1 ml Milli-Q water at 150°C for 12 hours. The supernatants are diluted to 40 g and are further prepared for Inductively Coupled Plasma Optical Emission Spectrometry analysis. We calculate mass accumulation rate (MAR) as a function of linear sedimentation rate (cm/ka) and dry bulk density (g/cm³). Sedimentation rates are obtained from the known reference points from the chronostratigraphic framework. The ODP reports obtain dry bulk density data (Peirce & Weissel, 1989; doi:10.2973/odp.proc.ir.121.115.1989). The accumulation rates of biogenic components (i.e., BAR, CaCO3 MAR, and bio-SiO2 MAR) are calculated as the product of MAR and the weight percent of biogenic components (wt%) in sediments. In the meantime, we analyze Baexcess to estimate export productivity (Pnew) following the algorithm equation after Dymond et al., 1992; doi:10.1029/92PA00181.

title: Saharan dust grain-size distributions collected in 4-day intervals from submarine sediment traps in the eastern tropical North Atlantic (2017-2018)

description: The following dataset comprises Saharan dust grain-size distributions from samples collected in submarine sediment traps in the eastern tropical North Atlantic Ocean during 2017 and 2018. The mooring was located at 12°N, 23°W and was deployed during the FORAMFLUX cruise in 2017 (doi: 10.2312/cr_m140) and recovered during the MACPEI cruise (doi: 10.2312/cr_msm79). Three funnel-shaped KUM sediment traps approximately 100m apart at depths 1074m, 1165m, and 1275m are referred to as traps U (upper), M (middle), and L (lower), respectively. The traps sampled at different time periods in order to span the collection period; L from August 2017-January 2018, M from February-June 2018, and U from July-November 2018. The traps were equipped with rotating carrousels each carrying 39 bottles in which the collected material was kept. The dataset features unprecedented resolution with each sample collected over 4-day periods, thus enabling the identification of individual dust outbreaks. Continuous sampling allowed for the observation of seasonal variations in grain-size distributions. Grain-size measurements were conducted using a Beckman Coulter Laser Diffraction Particle Size Analyzer LS13320 (LDA) at the Royal Netherlands Institute for Sea Research. The micro liquid module (MLM) was employed to detect fine grains ranging from 0.400 µm to 2.0 µm. The resulting grain-size distributions are provided as volume percentage versus 90 size bins. The LS13320 software supplies the metadata for the analysis, including the statistical parameters detailed in the dataset.

title: Inorganic and organic biogeochemical data from seagrass vegetated sediment cores collected in central Florida Bay

description: The dataset includes the porewater, surface water, and sediment geochemical data associated with the publication The unique biogeochemical role of carbonate-associated organic matter in a subtropical seagrass meadow Communications Earth and Environment, 2024. Modern surficial sediment cores (25 to 35 cm in length) were collected for porewater and sediment geochemical analysis at Bob Allen Keys, Florida Bay, USA on November 12, 2019. These sediment cores were collected from regions of relatively high and relatively low seagrass density (HD and LD, respectively), with seagrass biomass included in the sediment cores, and were collected as push cores 10 cm inner diameter. For solid phase analysis, one core was collected per seagrass density. For porewaters, 2 cores with drilled rhizon holes were collected per seagrass density. Solid phase data includes the total inorganic carbon content, the total organic carbon content, the atomic total organic carbon to total nitrogen ratio, and the delta-34 S stable isotopic value of chromium reducible sulfur. Porewater data includes the dissolved iron concentration, the delta-34 S stable isotopic value of dissolved sulfide and sulfate, and the delta-18 O stable isotopic value of sulfate. Additional samples were collected from the outlet of the Taylor Slough river, surface waters and porewater from Bob Allen (collected with a porewater sipper) for dissolved organic carbon concentration and delta-13 C composition, as well as absorbance at 254 nm. The data was collected to address the question of whether seagrass presence could contribute to increased sulfide oxidation in addition to increased sulfurization of organic matter, and whether this sulfide oxidation would lead to connectivity between particulate carbonate-associated organic matter and the dissolved organic matter pool. Molecular analysis of this dissolved organic matter and carbonate-associated organic matter (via FT ICR MS) which is also associated with the scientific publication is provided via open science framework (https://osf.io.vphzr/ at DOI 10.17605/OSF.IO/VPHZR). The sediment cores were also used for additional measurements published on Figshare (https://doi.org/10.6084/m9.figshare.16852792.v1).
