Marine Isotope Stage 5e diatom assemblages in marine sediment core PC509 (-68.31 degN, -86.03 degE, Cruise JR179)
This dataset presents the relative diatom abundances of 56 species/groups from the 132-120 ka interval in marine sediment core PC509 (-68.31 degN, -86.03 degE). This age interval corresponds to the peak of Marine Isotope Stage 5e (130- 116 ka). Microscope slides were prepared using a method adapted...

description |
This dataset presents the relative diatom abundances of 56 species/groups from the 132-120 ka interval in marine sediment core PC509 (-68.31 degN, -86.03 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 JR179 (2008) of the RRS James Clark Ross (https://epic.awi.de/id/eprint/29707/1/End2008a.pdf). 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 Chadwick et al. (submitted) align core PC509 to the LR04 chronology by correlating the sediment core wet bulk density to the LR04 benthic foraminifera δ18O stack (Lisiecki & Raymo 2005). Translation between the LR04 and EDC3 chronologies uses the conversion table in Parrenin et al. (2013). : Instrumentation: Piston 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 2-4 cm and age resolution of 0.6-1.3 ka. |
