title: Iron flux rates of sediment core EW9303-37JPC

description: Flux fusion measurements of elemental concentrations were used to calibrate the scanning X-ray fluorescence (XRF) Fe-count data from EW37JPC. Elemental intensities from EW37JPC were measured using an XRF core scanner (ITRAX, Cox Ltd., Sweden) at LDEO at 2-mm resolution, using an integration time of 10s and a molybdenum x-ray source set to 30 kV and 50 mA. The intensities were calibrated with flux fusion concentration measurements from EW37JPC. Sediment samples spanning the range of XRF intensities were randomized, interspersed with standard reference materials (e.g., JLS-1, JDO-1, SCO-1, AGV-2, DTS-2b, W-2a), ashed, digested in HF and HNO3 overnight, and diluted for analysis on an Agilent 720 Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) at LDEO. The ICP-OES data provide a robust calibration (R2=0.80 for Ca, R2=0.90 for Sr) for the high-resolution XRF records. We calculated Fe flux by multiplying the bulk sediment mass flux record (Zhou et al., 2021, DOI: 10.1016/j.epsl.2021.116910) by the calibrated Fe-concentration data.

description: We digitalized the North Atlantic Mid-Ocean Channel (NAMOC) and produced an Esri™ shapefile. The tracing of the NAMOC used a combination of the General Bathymetric Chart of the Oceans (GEBCO) bathymetry dataset (GEBCO Bathymetric Compilation Group, 2019, DOI: 10.5285/836f016a-33be-6ddc-e053-6c86abc0788e) and the published maps depicting the feature (see the linked publication).

title: Beam attenuation coefficient data from Carter Seamount station JC094-STN002 of the James Cook cruise JC094

description: The radiogenic isotope ratio 231Pa/230Th of seawater and ocean sediments is a potentially powerful tool for tracing oceanic processes such as the ocean circulation and marine primary productivity. However, 231Pa/230Th reflects the combined signal of multiple controls associated with scavenging and oceanic transport, limiting its use as a paleo-proxy. Given that links between seawater and sedimentary 231Pa and 230Th distributions are crucial for understanding the cycling and removal fluxes of these nuclides, we carry out analysis of 231Pa and 230Th in both seawater (dissolved phase) and modern sediment samples acquired from five depth transects across the northern tropical Atlantic open ocean during the JC094 research expedition which took place in October-November 2013. Measurements of the radiogenic isotopes were performed using a MultiCollector-Inductively Coupled Plasma-Mass Spectrometer (MC-ICP-MS). In addition, CTD beam attenuation coefficient measurements and XRF scan Fe and Ti measurements of two sediment cores collected from the region during the same research expedition are presented to aid interpretation of 231Pa and 230Th data. Here we show the CTD beam attenuation coefficient data near the Carter Seamount.

title: Algal pigment concentrations in the ocean during the Arctic MOSAiC-expedition

description: Algal pigment concentrations were retrieved from ocean samples, during the whole MOSAiC expedition (Multidisciplinary drifting Observatory for the Study of Arctic Climate) in 2019 to 2020. During MOSAiC, RV Polarstern anchored into an ice floe to gain new insights into Arctic climate over a full annual cycle. Ocean data were collected starting with the onset of the study, at 85 degrees north and 137 degrees east, following the drift towards the Fram Strait, and returning to the North Pole in the last leg of the expedition. Ocean samples were collected with a CTD, either from the ship, or from the ice floe in Ocean City (Rabe et al. 2022). Altogether 216 samples have been collected and analysed. After extraction in 90 % acetone, samples were analysed using high-performance liquid chromatography (HPLC) on a Waters system. Algal pigments contain a multiple set of information. Firstly, pigment concentrations can show the presence of algal biomass in the various water masses sampled. Secondly, marker pigments can reveal seasonal and temporal dynamics in algal community structure, by discerning specific algal classes like diatoms, cryptophytes, haptophytes and chlorophytes that have specific roles in biogeochemical cycles. Thirdly, certain pigments are indicative of the (photo)-physiological state of micro-algae and fourth, degradation products of the main chlorophyll a pigment further give an indication about senescence and grazing in the various habitats.

title: Ocean temperature, salinity and pressure time series from moored RBR Concerto and SBE Microcats during MOSAiC, from December 07 2019 to May 9 2020

description: Time series of temperature, salinity and pressure were recorded by instruments moored under drifting sea ice during the international Multidisciplinary drifting Observatory for the Study of the Arctic Climate (MOSAiC) expedition. The instruments combined in this dataset were mounted on two different vertical lines suspended below the sea ice, horizontally separated by approximately 100 m, spanning similar time periods:• 4 RBR Concerto CTDs were moored at depths of 7 m, 49 m, 97 m, and 202 m on a 200 m long thermistor string (the thermistor string itself did not return any data). Attached to the same mooring was also a MicroRider measuring temperature microstructure; this dataset is published separately. This mooring was deployed on Leg 1 (15.12.2019) and recovered on Leg 3 (09.05.2020).• 3 Seabird SBE37 Microcat CTDs were mounted on the metal frames of the cluster mooring at nominal depths of 20, 50 and 100 m. This mooring was deployed during Leg 1 (07.12.2019) and recovered during Leg 4 (31.07.2020), but the instruments were operational only until 02.02.2020.The RBRs were set to a sampling interval of 15 sec, while the Microcats were set to an interval of 5 min. Further information about the moorings and their context can be obtained from the Overview of the MOSAiC expedition: Physical oceanography (Rabe et al. 2022).For quality control, we performed de-spiking of the data and bin-averaged to 1h time intervals. We then calibrated each instrument against the profiling CTD (ship- and ice-based, Tippenhauer et al. 2023): Temperature and salinity from each CTD cast during the deployment period were compared to the (1h- bin-averaged) data point of the moored instrument closest in depth and time. This produces a time series of differences for temperature and salinity. A linear fit was performed to these time series to determine offset and trend between the instruments. Both offset and trend were then applied to the quality controlled 1-h bin-averaged data of the moored instruments. In this dataset, we provide the quality controlled and calibrated data at 1h interval as well as raw data from the instruments together with essential meta-data.

title: Global compilation of stable carbon (δ13C) and nitrogen (δ15N) isotope values of meso- and bathypelagic fish

description: Stable isotope analysis (SIA) has emerged as a valuable tool for understanding the trophic structure of the marine food web and gaining insights into trophic levels and niche. Researchers are increasingly utilizing SIA in studies focused on feeding ecology, particularly in estimating the long-term diets of meso- and bathypelagic fish. To facilitate this research, a global database of published data on stable isotopes, specifically δ13C and δ15N, of meso- and bathypelagic fish was created. The database was constructed by conducting a thorough search on Google Scholar and reviewing the references cited in the retrieved papers. The search primarily involved using popular terms such as stable isotope analysis or feeding ecology in combination with mesopelagic or bathypelagic fish. The resulting SIA database contains δ13C and δ15N values for 95 different species of meso- and bathypelagic fish, belonging to 27 families, with specimens collected between 2004 and 2015. Each entry in the database includes information on the sampling location, month and year of sample collection, taxonomic classifications (phylum, class, order, family), number of samples analyzed, as well as the reference and DOI of the original data source. This global SIA database holds significant potential as a valuable tool and data source for conducting large-scale meta-analyses.
