摘要

Vacuum line and oxidation procedures for conversion of dissolved, suspended and sinking particulate, and sedimentary organic matter to CO sub 2 for ion counting ( sup 14 C) by Tandem Accelerator Mass Spectrometry (AMS) and sample preparation for stable isotope (delta sup 13 C, delta sup 15 N) measurements have been completed, tested, and are currently in operation. To date, delta sup 13 C and delta sup 15 N have been measured in 12 samples of sinking particulate organic matter collected from a 98 day deployment (February-May, 1986, Cruise Cross II) and a 156 day deployment (May-October, 1986, Cross III) of ''Soutar.'' A total of 21 additional samples are prepared and have been or will be submitted to UCLA this spring for delta sup 13 C and delta sup 15 N measurements. The measurements of sup 14 C in the dissolved, suspended and sinking particulate, and sedimentary organic matter by AMS at McMaster University were originally scheduled for April, 1987. We had 11 samples of CO sub 2 derived from the oxidation of the above DOC and suspended particulate organic carbon (POC) samples, and were oxidizing 6 sinking POC and 5 sedimentary organic carbon (SOC) samples to CO sub 2 when a low-level sup 14 C contamination event occurred.
