University of Alaska Radiocarbon Dates I

Abstract

The radiocarbon dating laboratory in the Institute of Marine Science at the University of Alaska was established in the fall of 1968 and became operational a year later. Most of the samples examined have been from Alaska and consist largely of wood and peat.

Anaerobic methane oxidation: Rate depth distributions in Skan Bay sediments

“…Sulfate samples were collected in pre-weighed bottles containing HC1. Sulfate was separated using ion exchange and evaporation [15] and was analyzed by conductometric titration [16]. The CH4, ~;CO2 and SO~-depth distributions in Skan Bay sediments are shown in Fig.…”
