Burn Terrestrial Data
Title Abstract
Burned soil surface radiocarbon values for moss macrofossils plucked from the Anaktuvuk River Fire sites
We used radiocarbon dating of the organic soil surface remaining post-fire to examine whether the fire burned into ancient and likely irreplaceable soil C pools. Suprisingly, it did not; all radiocarbon dates from burned soil surfaces contained bomb carbon, setting the maximum age of the burned soil surfaces at ~50 years.
Landscape Interactions Chemistry
Title Abstract
Radiocarbon and del 13C was determined on dissolved organic carbon collected from Imnavait Creek 1990 and 1991.
Del 13C was determined on dissolved organic carbon from Imnavait Creek water collected from the fourth pond upstream of the Imnavait Creek flume in 1990 and 1991. Radiocarbon was determined on a sample in each year.
Terrestrial Soil Properties
Title Abstract
Peat cores were collected along the Dalton Highway for the analysis of soil properties, 13C and percent of modern age, North Slope, Alaska 1989.
Peat cores were collected along the Dalton Highway in 1989 and analysed for percent moisture, percent organic carbon, bulk densitey, del C-13, and radiocarbon content at varying depth intevals throughout the core. Samples were collected to the mineral zone and kept in cold storage until analysis. Samples were collected from 12 sites.
Radiocarbon dates for an elevational gradient by Toolik Lake, North Slope of Alaska 1988.
Two cores of peat, approximately 15 cm2, were cut to the depth at which mineral soils were encountered at each site. The sites of sampling correspond to an elevational gradient leading from the lakeside upslope to the begining of the water track at the ridgetop. Each sample was divided into three sections, one section to be used for radiocarbon age , one for loss on ignition, and the remainder to be kept for future needs.
