Ice Ages - Solving the Mystery
John Imbrie and Katherine Palmer Imbrie PSU QE697.I45 1979
Nice history of ice age science. Did not read whole book, no time.
Chapter 12: Milankovitch Revival
Correlation of histories of sea level change
Chapter 13: Signal from the Earth
- 1906 Bernard Brunhes learns bricks and then rocks freeze in Earth's magnetic field as they cool
- 1930's? Motonori Matuyama finds reversals in lava flows in Japan and Korea
- 1955-1965 proof of worldwide correlation
- Vruhes-Matuyama boundary 700 kya, later found in deep-sea cores
Chapter 14: Pulsebeat of Climate
- ice sheets large, central Europe polar climate, windy with loess deposits.
- ice sheets small, warm and wet with broadleaf trees
- oxygen-isotope ratio varies from 0 to -2 (something), 6 times in 400 Ky
Ch 15: Pacemaker of the Ice Ages
- 1971 CLIMAP project
- International Decade of Ocean Exploration IDOE. Columbia, Brown, OSU; later Maine and Princeton, later worldwide
Ch 16: The Coming Ice Age
- Photocopy on file
- Fig 43 shows temperature variation over last 11 ky, with a climatic peak ("optimum") at 6.5 kya, and a 6C colder minimum at 10.5 kya. The "little ice age" is shown. No citation for the data source, it may be illustrative rather than a direct plotting of data.
Fig 45 is the last 1000 years, with the "little ice age" featured, adapted from H.H. Lamb 1969
