Abstract:
Accumulation rates (fluxes) of benthic (BFAR) and planktonic (PFAR) foraminifera spanning the last deglaciation and early Holocene (16.5 – 10 ka BP) of MSM09/2_455-13 (GeoTü SL 170) from the central eastern Baffin Bay. Prior to foraminifera counting, sediment samples were freeze-dried, then washed over a 63 and a 150 micrometre sieves before oven-drying (at 40 degC). Counts were made manually on both >150µm and 63 – 150µm fractions using a stereomicroscope (approx. 80 – 120 magnification). Split size is indicated; 1 = whole sample. The only planktonic species found was Neogloboquadrina pachyderma and benthic assemblage data from this core can be found here (https://doi.org/10.1594/PANGAEA.974030). Accumulation rates were calculated by multiplying the planktonic or benthic foraminiferal concentration (individuals g-1) in each size fraction by the mass accumulation rate (MAR; g cm2 ka-1). The MAR was calculated by multiplying dry bulk density (see Andersen et al.,2017 https://doi.org/10.1007/978-94-024-0990-1_6) by the linear sedimentation rate from our age model (cm ka-1). Planktonic/benthic ratios are also included for each size fraction.
