Sentences with phrase «oxygen isotope record»

The new sea - level record was then used in combination with existing deep - sea oxygen isotope records from the open ocean, to work out deep - sea temperature changes.
Using long drill cores and uplifted sections of sea - floor sediments, previous work had analysed such microfossil - based oxygen isotope records from carefully dated sequences.
Evidence for approximately contemporaneous global cooling in sediments that do contain YTT glass shards has been found in marine core oxygen isotope records from the South China Sea (3), as have terrestrial carbon isotope and pollen records from Northern India and Bengal (23).
Novel precipitation isotope records address a long - standing debate about East Asian cave oxygen isotope records Elizabeth Thomas, Steve Clemens, Tim Herbert, Yongsong Huang, Warren Prell, Jaap Sinninghe - Damsté, Youbin Sun
Oxygen isotope records indicate that interglacial periods have typically lasted 10,000 — 15,000 years, and maximum glacial periods were of similar length.
The continental glaciations of the Pleistocene left signatures on the landscape in the form of glacial deposits and landforms; however, the best knowledge of the magnitude and timing of the various glacial and interglacial periods comes from oxygen isotope records in ocean sediments.
To use your own research as an analog, I find it somewhat like trying to figure out what part of the deep - sea oxygen isotope record is due to ice - volume vs. temperature changes (and all other issues) to within less than a percent understanding.
These directly measured temperatures represent a rough average — a record of trends, not variable, daily temperatures — but climatologists can compare the thermometer temperatures with the oxygen isotope record as a way to calibrate those results.
HS12 uses the oxygen isotope record in ocean sediments Zachos et al. (2008) to estimate past changes of sea level and ocean temperature, and thus obtain a largely empirical estimate of climate sensitivity.
