The year 1950 is taken as ‘present’ because the term BP is usually applied to radiocarbon dates ( see radiocarbon dating ) and the atmospheric testing of atomic weapons has greatly modified the radiocarbon content of all organisms since about 1950 , so this is taken as the datum horizon for this...

... ( bp ) [Ab] Before Present. A term widely used by Quaternary geologists and archaeologists with reference to radiocarbon ages and results from other radiometric dating techniques. The present is conventionally taken to be the calendar year ad 1950 . Use of the lower‐case form or the abbreviation RCYBP ( Radiocarbon Years Before Present ) is generally taken to mean the raw ages as calculated by the determining laboratory. These are not calendar years. Use of the upper‐case form or the abbreviation CalBP ( Calibrated Before Present ) shows that the...

...BP curve A curve depicting balance of payments equilibrium in the IS – LM model . The BP curve is drawn on the same diagram as the IS and LM curves and shows combinations of Y ( gross domestic product ) and r (the interest rate) at which the overall balance of payments is in equilibrium. This means that the current and capital account balances of payments sum to zero. As higher Y tends to produce a current account deficit, and higher r tends to produce a capital account surplus, the BP curve is upward sloping. If international capital...
