Comparison of Large and Ultra-Small Δ 14 C Measurements in Core Top Benthic Foraminifera from the Okhotsk Sea
The radiocarbon activity of benthic foraminifera was investigated in surface sediments from a high deposition rate location at a depth of 1000 m in the Okhotsk Sea. Sediments were preserved and stained with Rose Bengal to identify foraminifera that contain cytoplasm. The benthic fauna at this site is dominated by large specimens of Uvigerina peregrina , and bulk samples (∼150 individuals) of stained and unstained specimens were dated. The stained…
Improvements in Procedural Blanks at Nosams
During the four years the Sample Preparation Laboratory (SPL) at the National Ocean Sciences Accelerator Mass Spectrometer (NOSAMS) Facilty has been in operation we have accumulated much data from which we can assess our progress. We evaluate our procedural blanks here and describe modifications in our procedures that have improved our analyses of older samples. In the SPL, we convert three distinct types of samples—seawater, CaCO 3 and organic c…
The Rapid Preparation of Seawater ΣCO 2 for Radiocarbon Analysis at the National Ocean Sciences Ams Facility
We have established a laboratory for extracting ΣCO 2 from seawater samples for AMS analysis of the radiocarbon content. The seawater samples are collected at sea, poisoned and stored until analysis in the laboratory. Each sample is acidified; the inorganic carbon is stripped out as CO 2 with an inert carrier gas and then converted to graphite. We present results for Buzzards Bay surface H 2 O and Na 2 CO 3 standards that demonstrate we strip >98…
