Conventional ages cannot be directly translated into calendar years; this requires a further step.When radiocarbon dating was developed, it was assumed that the concentration of 14C in the atmosphere was constant over time.
However, not all countries have their own specific numbering system.
Most laboratories report radiocarbon determinations as "Conventional Ages." The Conventional Age for the sample Wk-2191 (below) is 510 ± 50 BP.
Site numbers in the United States are based on the "Smithsonian Trinomial System" where each State has its own number (e.g., WA=45), the County within the state has a two letter abbreviation (e.g., Crook County = CR), and sites within the county are given numbers consecutively as they are found and recorded (i.e., 45xxnnn).
So, a site labelled as "45CR121" would be the 121st site recorded in Crook County, Washington.
The tables below present information on dated samples from New Zealand (South Pacific) and Trinidad (Southern Caribbean).
The radiocarbon ages indicated here are not directly equivalent to calender years.
The Unit co-ordinates fundamental and applied research at this University and elsewhere on thermophilic bacteria, genes and enzymes.
Research is predominantly funded by research contracts and collaborations exist with many national and overseas laboratories.
The primary mission of the International Centre for Terrestrial Antarctic Research (ICTAR) is to promote the protection of Antarctica through integrated international research into Antarctic terrestrial ecosystems, assuring New Zealand's continued leadership in this area.
SERG has expertise in solar thermal, photovoltaic and optical modelling, specialising in building integrated systems.
