Marine Isotope Stage 5e diatom assemblages in marine sediment core MD03-2603 (-64.28 degN, 139.38 degE, Cruise MD130)
This dataset presents the relative diatom abundances of 55 species/groups from the 132-120 ka interval in marine sediment core MD03-2603 (-64.28 degN, 139.38 degE). This age interval corresponds to the peak of Marine Isotope Stage 5e (130- 116 ka). Microscope slides were prepared using a method adap...

description |
This dataset presents the relative diatom abundances of 55 species/groups from the 132-120 ka interval in marine sediment core MD03-2603 (-64.28 degN, 139.38 degE). This age interval corresponds to the peak of Marine Isotope Stage 5e (130- 116 ka). Microscope slides were prepared using a method adapted from Scherer (1994) and 300+ diatom valves were counted for each depth sample to produce the relative percentage abundance of each diatom species/group. This project was funded by the UK Natural Environment Research Council Grant NE/L002531/1 : Sediment core material was collected on Cruise MD130 (2003) R/V Marion DuFresne II (https://doi.org/10.17600/3200040). For the diatom assemblage data, microscope slides were produced using a method adapted from Scherer (1994). Samples of 7-20 mg were exposed to 10% Hydrochloric acid to remove any carbonate, 30% Hydrogen peroxide to break down organic material and a 4% Sodium Hexametaphosphate solution to promote disaggregation and placed in warm water bath for minimum 12 hours. The material was homogenised into a ~10cm water column and allowed to settle randomly onto coverslips over a minimum of 4 hours. The water was drained away and coverslips were mounted on microscope slides with Norland Optical Adhesive (NOA 61). Slides were investigated with a light microscope (Olympus BH-2 at x1000 magnification) and a minimum of 300 diatom valves were counted for each sample. Age Model Presti et al. (2011) align core MD03-2603 to the LR04 chronology by correlating the sediment core Ba/Al and Ba/Ti ratios to the LR04 benthic foraminifera δ18O stack (Lisiecki & Raymo 2005). Translation between the LR04 and EDC3 chronologies uses the conversion tables in Parrenin et al. (2013). : Instrumentation: Calypso corer, Diatom settling tanks and bench, Olympus BH-2 light microscope. : All diatom abundance values have an error of ±0.16 %. Ages for samples have a chronological uncertainty of ~2 ka. Sediment samples have a depth resolution of 4 cm and age resolution of 0.4-0.9 ka. |
