Sentences with word «paleothermometer»

Juillet - Leclerc, A., and G. Schmidt, 2001: A calibration of the oxygen isotope paleothermometer of coral aragonite from Porites.

As to the technical parts, as described in many sources, we have lots of paleothermometers for the central Greenland ice cores over the last 100,000 years, providing multiple validation and high confidence that temperatures have been estimated accurately.

Unlike previous methods, the clumped isotope paleothermometer technique does not rely on assumptions about the isotopic composition of seawater.

The group highlighted the added value of measuring paired coral strontium / calcium ratios (Sr / Ca) and oxygen isotope ratios (δ18O), two key proxies for sea surface temperature that are often referred to as paleothermometers (δ18O also reflects sea surface salinity).

The classic paleothermometer is the stable - isotopic composition of water in the ice core (10).

Ice cores are local paleothermometers, telling past temperature where they are (or where the snow fell, if glacier flow has caused ice in a core to have come from a significant distance).

Both events were accompanied by warming episodes the U-M-led team found by analyzing the chemical composition of fossil shells using a recently developed technique called the carbonate clumped isotope paleothermometer.

The research team used large bottom - dwelling forams as «paleothermometers» to gain a more precise temperature reading.

In a new study scientists used «paleothermometers» to gauge CO2 and temperatures that prevailed during a long - lived primordial global warming event, and found CO2 to be the culprit

``... Major climate anomalies recorded by the MBT / CBT - paleothermometer are, for instance, the Little Ice Age (~ 14th to 19th century) and the Medieval Warm Period (MWP, ~ 9th to 14th century).»

Bacterial GDGTs in Holocene sediments and catchment soils of a high Alpine lake: application of the MBT / CBT - paleothermometer, Niemann et al, 2012, read more here.
