title: Age determination of Northwest Atlantic sediment cores

description: This dataset contains new and updated age models for sediment cores from depth transects at Blake Outer Ridge and Cape Hatteras. Primarily, this includes new AMS-14C ages measured on planktic and/or benthic foraminifera, as well as δ18O (and other) tie points. We also include previously published 14C that has been recalibrated using new reservoir ages and updated calibration curves (Marine 20; ∆R=-128±68; Heaton et al., 2020). AMS-14C measurements were made at the NERC NEIF Radiocarbon Laboratory (University of East Kilbride, Scotland, UK), KCCAMS Radiocarbon Facility (University of California, Irvine, CA, USA), and NOSAMS Facility (Woods Hole Oceanographic Institution, MA, USA), following standard procedures.

title: Geochemical composition of nodules and crusts from the Indian Ocean recovered from R/V Marion Dufresne expeditions from 1977 until 1981

description: Following the launch of the "Marion Dufresne 1", first supply ship of the Terres Australes and Antarctiques Françaises and part time oceanographic vessel in the Indian Ocean, a new marine geology program was developped at the Laboratoire de Géologie, MNHN. The first oceanographic cruise of the "Marion Dufresne 1" started in 1973 in the Southwestern Indian Ocean (OSIRIS I cruise). Forty piston-cores recovered nearly 200 m of sediments consisting in the first of the 450 cores of the Indian Ocean collection now deposited at the Museum. L. Leclaire being Director from 1980 to 1991, a multidisciplinary team (including sedimentologists and micropaleontologists) was involved in many oceanographic cruises in the Indian Ocean. Marine sedimentology was developped during annual cruises programs in collaboration with geophysicists, geochemists, and biologists. In 1995, the "Marion Dufresne 2" replaced the initial "Marion Dufresne 1".
description: From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.

title: Incubation data from sediment cores from the North Pacific CDisK-IV expedition

description: Duplicate cores from each station were incubated in a cold room (2°C) for 6-14 days to provide constraints on elemental fluxes to and from the seafloor. An incubation cap was inserted into each core, and the water level adjusted to ~12 cm above the sediment surface. A 12 V motor in the incubation cap stirred the overlying water at 30 rpm. 5-7 samples were collected during the incubation period and filtered through 0.45 µm PES filters. The table provides information regarding the change in overlying water concentrations of Ca, Sr, K and Mg during the incubation experiments.

title: Calibrated stable water vapor isotope data at 2.5 m ASL and 50 m ASL from Tudor Hill Marine Atmospheric Observatory, Bermuda (2013)

description: Stable water vapor isotopologues (d18O and dD) and mixing ratio (ppmv) observations from 2.5 m and 50 m levels above sea level surface. The data was collected between 2013-06-20 and 2013-12-30 at the Tudor Hill Marine Atmospheric Observatory (THMAO) tower of Bermuda Institute of Ocean Sciences (32.2647° N 64.8788° W). Water vapor observations were collected to study isotopic fractionation processes during ocean evaporation. The instrument used was a Picarro cavity ring-down spectroscopy analyzer (model L-2120i). The data was corrected for the humidity-isotope response of the instrument and calibrated on the VSMOW-SLAP scale. Observations at the two inlets are synchronised and resampled every 30 minutes using a common UTC timestamp (Zannoni et al., 2022). The estimated precision is 0.14 ‰ for d18O and 1.1‰ for dD following Steen-Larsen et al. (2014).

title: Integrated annual calcium carbonate production of planktic calcifiers in the North Pacific from the R/V Kilo Moana cruise KM1712

description: This dataset compiles the estimates of annual CaCO3 production, including the upper and lower limits of the estimates, for the 4 planktic calcifying groups considered in the study, the pteropods (mg/m²/yr), the heteropods (mg/m²/yr), the foraminifers (mg/m²/yr) and the coccolithophores (mg/m²/yr). The estimates derived from the living standing stocks of these 4 groups of organisms collected in the North Pacific between Hawaii and the Gulf of Alaska during the R/V Kilo Moana cruise KM1712 in August 2017. R code was used to calculate the integrated annual CaCO3 production for the different organisms, including the upper and lower limits (Gray, 2022).
description: Jess F. Adkins and William M. Berelson were chief scientists of the Kilo Moana cruise KM1712. Patrizia Ziveri and William R. Gray designed the sampling strategy and estimated the integrated annual calcium carbonate production of planktic calcifiers.

title: Derived geomorphic features (shapefiles) from multibeam bathymetry processed data (Kongsberg EM 122 working area dataset) of RVIB NATHANIEL B. PALMER during cruise NBP150-02

description: Bathymetry from multibeam echo sounding data in Pennell Trough, Ross Sea, Antarctica was collected onboard the RVIB Nathaniel B. Palmer (NBP) 15-02 cruise using a Kongsberg EM122 operating in dual swath mode at 12 kHz frequency with a 1°×1° beam width, swath angular coverage set to 62°×62°, and 30-60% overlap between survey lines. All raw, ping-edited geophysical data collected on NBP150-02 can be accessed using the Marine Geoscience Data System (Cruise DOI: 10.7284/901477). The bathymetry dataset here is gridded at 20-m resolution with a water depth-dependent vertical resolution on the order of decimeters. Two shapefiles are provided for ice-marginal landforms and meltwater landforms observable in the bathymetry data. The purpose of collecting the bathymetry data on cruise NBP15-02 was to better understand the glacial history of the Ross Sea, and the dataset, inclusive of bathymetry data and shapefiles of glacial landforms, from Pennell Trough are used to understand impacts on subglacial channel morphology and organization during the deglaciation of the region following the Last Glacial Maximum.

title: Salinity, temperature and optical backscatter data measured with a Bottom Boundary (BOBO) lander at the Gardar Drift in the North Atlantic

description: To monitor particle fluxes and near bottom hydrographic variability a modified version of the benthic Bottom Boundary (BOBO) lander was deployed at 57° 29.09 N, 27° 54.53 W on the Gardar Drift at a water depth of 2630 m. These measurements cover the period from 16/09/2007 to 09/09/2008. Salinity and temperature were logged every 15 min at 3 metres above the seafloor with an SBE-16 CT sensor. Two Seapoint optical backscatter sensors were fitted to the lander at 1 and 3 metres above the seafloor recording data every 15 min. Biofouling of the sensor windows may have affected the results, and the lowest sensor (1 mab) appeared temporarily saturated by high turbidity. Full details about the deployment can be found in Jonkers et al., 2010 (doi:10.1016/j.dsr.2010.05.005).

title: Highly branched isoprenoids in lake photic zone water

description: Diatom-derived highly branched isoprenoids (HBIs) are found extensively in marine sediments, but are observed in a limited number of lake sediments. To expand on this record, between 2022 and 2024, we collected lake surface sediment samples from 50 lakes in the United States of America from the Midwest and Northeast. Studied lakes capture a range in climate, water chemistry (e.g., pH, salinity, alkalinity), size, and trophic states. Lakes also vary in their diatom species compositions. Water samples from the photic zone were collected using an integrated water sampler. The integrated sample was designed to collect the water from the euphotic zone where phytoplankton are concentrated. Water was sampled from the euphotic zone (calculated as 2 times the Secchi disk depth) using an integrated water sampler fabricated from a 2 m long x 5.2 cm ID PVC pipe (2" nominal schedule 40 PVC pipe) fitted with a ball valve at the top. When the euphotic zone was &gt;2 m, only the upper 2 m was sampled. When the euphotic zone intersected with the sediment/water interface, water was collected from the surface to 0.5 m above the sediment/water interface. Waters were filtered first through 1000 µm mesh filter and then onto a 0.7 µm glass fiber filter. Filters were extracted and analyzed by gas chromatography mass spectrometry.
