Sentences with phrase «isotopic events»

Two speakers from the Geological Society conference «Past Carbon Isotopic Events and Future Ecologies» came to the SMC to discuss climate clues from the geological record and what they can tell us about present and future changes to the climate.

A long lifetime for CO2 adjustment is also consistent with an isotopic event in the deep sea sedimentary record from 55 million years ago, the Paleocene / Eocene Thermal Maximum event.

Not exact matches

The sediments in Sky Pond in the Rocky Mountains show that around 1950 nitrogen began to flood the lake, an event unprecedented in at least 14,000 years and this isotopic record too could have a pretty precise start date: July 2, 1909 when Fritz Haber first demonstrated how to make ammonia from the air in Germany.

The Toba volcanic event and interstadial / stadial climates at the marine isotopic stage 5 to 4 transition in the Northern Indian Ocean

[Response: Methane is the «usual suspect» for those events, such as the Paleocene Eocene thermal maximum, because it is easier to explain the carbon isotopic spikes if the source is strongly isotopically labeled.

Wouldn't future isotopic studies of tree rings peg this rain event as originating from a tropical cyclone of some sort?

Isotopic signatures can be used to date past events of methane release, as well as their duration.

While useful in the broadest sense, these isotopic systems currently lack the temporal resolution to discern rates of redox change across the event.
