title: Chironomid percentage-abundances for surface sediment samples obtained from 8 lakes in the Plymouth area (Massachusetts, US)

description: This dataset provides the percentage-abundances of chironomid taxa identified in a set of surface sediment samples taken in the Plymouth area (Massachusetts, United States) in 2009. For each sample, a short sediment core was retrieved from a rubber dinghy using a gravity corer (both the Glew and the mini-Glew models were used) during field work in June and September 2009. Volumetric samples taken from the 0-1cm sediment depth sample were subsequently processed in the laboratory (University of New Brunswick, Canada) using standard protocols. The procedure involved placing the sample aliquot in a glass beaker and submerging it in warm 10% KOH for ca. 20 mins. Subsequently the material was rinsed over a 100µm mesh and individual head capsules were hand-sorted from the residue and mounted on microscope slides. Chironomid head capsules were identified using Brooks et al. 2007 and encountered taxa that were not present in that handbook are illustrated and described in Engels & Cwynar (2011). This dataset provides chironomid abundances (expressed as percentage of the total chironomid sum) as well as measurements of water depth for each of the samples; Engels & Cwynar (2011) provide additional environmental observations for each of the 8 lakes sampled. A total of 132 surface sediment samples were originally counted, but as 3 samples only reached total chironomid count sums of less-than-50 these were removed from the original dataset, resulting in a final dataset consisting of 129 samples. The chironomid data provides information on within-lake distribution patterns of chironomid taxa for each of the 8 lakes sampled. The dataset was used to determine depth-preferences of each of the taxa encountered, and to determine common threshold depths (i.e. those water depths where abrupt changes in the composition of the chironomid fauna take place). These data were subsequently used to produce site-specific (i.e. one lake) and regional (i.e. 7- or 8-lake) chironomid-water depth inference models.
description: Surface samples obtained from 8 lakes, with different number of samples taken from each lake: Bloody Pond – 19 samples; Crooked Pond – 26 samples; Deep Pond -5 samples; Dicks Pond – 6 samples; Little West Pond – 9 samples; Long Pond – 25 samples; Micajah Pond – 25 samples; UP: Union Pond – 14 samples. Ceratopogonidea head capsules and Chaeborus mandibles are included in line with other publications from the Nearctic region.Stenochironomus type "Mt" was counted as a separate taxon by Engels & Cwynar 2011; it is easily distinguished from the typical Stenochironomus morphotype as it only has 1 single median tooth. Later it was found that this taxon actually represents 1-instar Stenochironomus larval head capsules. In future studies, it should be amalgamated with Stenochironomus.

title: Carbon monoxide stable isotope data from laboratory heating experiments and collection of air from Stony Brook, NY, on Long Island, 2019-2022

description: Clumped isotope data of carbon monoxide (analyzed as CO oxidized to CO2) from laboratory heating experiments and collections of natural air samples from the campus of Stony Brook University from 2019-2022. Air sampling was done from the School of Marine and Atmospheric Sciences building roof (Dana Hall), see doi:10.1594/PANGAEA.971624. Laboratory heating experiments equilibrated CO in tube furnaces at elevated temperatures 300-1000 °C for periods of hours to days. These heating experiments were done (1) in the presence of platinum wire, (2) by the reaction of graphite with CO2, and (3) by the decomposition of calcium carbonate in the presence of Zn metal.

title: Sodium incorporation in foraminiferal calcite: an evaluation of the Na/Ca salinity proxy and evidence for multiple Na-bearing phases

description: New and compiled Na/Ca measurements of the planktonic foraminifera Globigerinoides ruber. The dataset contains data from foraminiferal samples 1) collected from plankton tows and sediment traps which span a wide salinity range (32.5 - 40.7 salinity units) across the Bay-of-Bengal, Arabian Sea, and Red Sea, 2) cultured in the laboratory under varying carbonate chemistry, and 3) a globally-distributed suite of core-top samples. Na/Ca was measured using both solution and laser ablation ICP-MS. The foraminiferal Na/Ca data are provided alongside environmental parameters for each sample (e.g. temperature, salinity, pH, bottom water Omega calcite), in order to assess the environmental controls on Na/Ca in foraminifera. The data accompany the following manuscript: Gray et al. (2023, doi:10.1016/j.gca.2023.03.011).

title: Oxygen and carbon isotopes rom the shells of Globorotaloides hexagonus from sediment core TR163-23

description: Here we document the stable isotope (δ18O and δ13C) from the shells of planktic foraminifer Globorotaloides hexagonus from Eastern Equatorial Pacific core site TR163-23 (0° 24.6' N, 92° 9.6' W; 2,730 m depth). Morphometric measurements include the length of the shell along the longest dimension from the final chamber, the number of chambers in the final whorl, and porosity. Porosity was assessed by the percentage of surface area on the final chamber consisting of pores. Stable isotope analyses were carried out on pooled samples of 3-10 shells, while morphometrics were measured in individuals.

title: Mg/Ca ratios measured by Electron Probe Microanalyzer in shells of the planktic foraminifer Morozovella velascoensis from ODP Site 865 (Central Pacific) across the PETM (~56 Ma)

description: Foraminiferal shells of the species M. velascoensis from sediments spanning ~650 ka across the PETM section of ODP Site 865, Central Pacific, were embedded in epoxy and polished to midsection. Suitable, well-preserved domains for in-situ analysis were identified by scanning electron microscopy. In-situ measurements of the Mg/Ca ratios were performed using a CAMECA SX-51 electron microprobe housed in the Cameron and Wilcox Microbeam Laboratory at the UW-Madison Department of Geoscience. Depending on the number of suitable targets for analysis, between one and seven Mg/Ca measurements were performed for each shell. Fully quantitative microanalyses (mineral standards, background subtracted, and matrix corrected) were performed using Probe for EPMA software (Probe Software, Inc.). The natural carbonate standards Delight Dolomite and Callender Calcite were used for Mg and Ca, respectively. Mg-K alpha X-rays were measured on two spectrometers and aggregated. Carbon was calculated within the matrix correction, being allocated as one atom of carbon to 3 atoms of oxygen, and oxygen by stoichiometry to the cations measured, thus analytical totals of 98 – 100.5 wt. % are a measure of accuracy. Analyses featuring analytical totals below 98 wt. % or above 100.5 wt. % were excluded from the data set.

title: Alkenone concentration of ODP Site 145-883

description: Here we present concentration and mass accumulation rate of C37 alkenones in discrete samples from ODP site 883. Approximately 1–4 g of sediment was freeze-dried and homogenized prior to extraction with a Dionex 200 Accelerated Solvent Extractor using 100% dichloromethane. Prior to quantification, the total lipid extract was evaporated under N2 and redissolved in 200 μL toluene spiked with n-hexatriacontane (C36) and n-heptatriacontane (C37) standards. Alkenone concentrations were calculated by comparison of C37:2 and C37:3 alkenone peak areas to the peak areas of the C36 and C37 internal standards determined by an Agilent Technologies 6890 gas chromatograph flame ionization detector (GC-FID), with an Agilent Technologies DB-1 column (60 m, 0.32 mm diameter, 0.10 mm film thickness). 1 μL of total lipid extract was injected at an initial temperature of 90°C, increasing to 255°C at 40°C/min, then to 300°C at 1°C/min, ramping to 320°C at 10°C/min, and ending with an isothermal hold at 320°C for 11 minutes. 228 of 504 samples were analyzed at least in duplicate, yielding a mean standard deviation of 0.017 pmol•mg-1 or 9.2 ng*g-1.

description: Here we present a new astronomically tuned age model for ODP site 887. Age control points established by correlation of GRAPE WBD at site 887 to our site 883 composite and the excellent shipboard magnetostratigraphic age model, with reversal depths updated to fit the new composite section. Where paleomagnetic polarity reversals were recorded in sediments from both 887A and 887C, the mean composite depth of the reversal was used for the age model. In all cases, the discrepancy of the paleomagnetic reversals in composite depth between 887A and 887C was approximately the same as the sampling interval of the magnetic inclination measurements (10 cm).

title: Compiled Late Pliocene Stable Carbon Isotope Data from Sites in the Atlantic and Pacific Ocean

description: Here we compiled stable carbon isotope data from 23 ODP sites in the Atlantic and Pacific, binned by marine isotope stage.Stable carbon isotope data were binned and averaged according to the marine isotope age assignments in the LR04 and the reported ages of the samples from each site. Only Cibicidoides wuellerstorfi values were used, although sometimes measured species was not reported for each sample by the original publication. Please note that some sites have data originating from multiple publications.Calculated values for whole basin δ13C of dissolved inorganic carbon, calculated Δδ13C, and associated uncertainties from the values compiled in MPWP_benthic_isotope_data_compilation. Benthic δ13C data from all sites below 2000 meters water depth were binned by marine isotope stage as defined by the age bounds provided with the LR04 stack. Because of our focus on specific MIS events, sedimentary records with low-resolution age models were excluded. All data are derived from Cibicidoides wuellerstorfi. In datasets composed of isotope measurements of two or more benthic foraminifera species (e.g., ODP 883), only C. wuellerstorfi δ13C data were used. The mean of the binned data across the entire isotope stage from each site was then used to calculate a mean deep Pacific and mean deep Atlantic δ13CDIC estimate for all 11 marine isotope stages in the MPWP, assuming a 1:1 relationship between C. wuellerstorfi δ13C and δ13CDIC. All sites were weighed equally.

title: Benthic foraminifera isotope ratios of ODP Site 145-887

description: Here we present stable carbon and oxygen isotope data measurements of C. wuellerstorfi in discrete samples from ODP 887A. Samples were freeze dried, weighed, soaked in water for 24 hours to disaggregate, and wet sieved using a 150 μm mesh sieve. Samples were then dried at 40°C. Select genera and species were picked and comprehensively counted from the 150–355 μm fraction. Insufficent specimens were recovered for replicate analyses. Specimens selected for isotopic analysis were cleaned with 70 μL ethanol and sonicated for 30 seconds. Ethanol was drawn off with a pipette, and specimens were dried overnight at room temperature. Isotope ratios were quantified at the Brown University stable isotope facility with a Finnigan Mat 252 with Carbonate Kiel III autosampler, in which individual samples were reacted with 70°C H3PO4. Cibicidoides δ18O values were adjusted by +0.64‰ to Uvigerina values. Cibicidoides mundulus isotopic values were taken as equivalent to C. wuellerstorfi. Only C. wuellerstrofi values should be used for analysis of stable carbon isotope data.
