  • Update Regarding Multitracks + Registration

    It's clear that this thread needs some love and attention. A lot of the links have either expired or been miss-labelled. With the amount of tracks there are, this is quite a practice. I have made the decision to lock this thread from further replies and to put out this notice that I will be refreshing this thread with updated links and guidance where needed.

    I will update the thread on multitracks and the first post with any forth coming updates about this in due course. For information - I have also disabled user registrations to do some tidyup. Stay tuned.

Before Present (BP) years, or "years before present" is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred before the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale. The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, making carbon dating after that time likely to be unreliable.In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP is explicitly Radio Carbon Years Before Present.
