The name Cretaceous is derived from creta, Latin for chalk, and was first proposed by J.B.J. Spanning 79 million years, it represents more time than has elapsed since the extinction of the dinosaurs, which occurred at the end of the period. This ventilation age can be estimated in the past by measuring the. Water mass ventilation provides an important link between the atmosphere and the global ocean circulation. The Cretaceous is the longest period of the Phanerozoic Eon. bulloides and on the radiocarbon ages obtained from planktonic foraminifera samples. A simple relationship is derived, valid for stationary transport, between the transient evolution, τ id(r,t), of the idealized age tracer and the "age spectrum," G(r,t), the distribution of times t since a water mass was last ventilated. The presence of these three water masses in the Atlantic Ocean is evident in. Here it is shown that this information can be readily interpreted in terms of the ventilation histories of water masses. However, in principle the transient solution provides more information about the transport. The use of tracer inventories provides an independent means of estimating water mass formation rates. In most studies only the steady-state distribution, the result of many centuries of model integration, has been presented and analyzed. This survey offers the possibility to extract a wealth of new results on the physical climate system and biogeochemical processes. The idealized age tracer is commonly used to diagnose transport in ocean models and to help interpret ocean measurements.
