Influence of the intertropical convergence zone on the East Asian monsoon

Article Abstract:

The influence of Asian-Australian monsoon on the societal and economic activity and the high-resolution records of the magnetic properties and the titanium content of the sediments of Lake Huguang Maar in coastal southeast China, are described. The analysis has shown that migrations in the intertropical convergence zone might have contributed to the declines of both the Tang dynasty in China and the Classic Maya in Central America.

Rapid environmental changes in southern Europe during the last glacial period

Article Abstract:

High-resolution geochemical, physical and pollen data from lake sediments in Italy and from a Mediterranean sediment core are presented. The lacustrine sequence extends to the past 102,000 years, and many features correspond well with the Greenland ice-core records. This shows that the influence of the ocean-atmosphere system of the Northern Hemisphere extended as far as the central Mediterranean region.

Nicholas Shackleton (1937-2006)

Article Abstract:

Nicholas Shackleton had developed a mass spectrometer in the early 1960s, that could analyze oxygen isotope ratios in foraminifera, tiny calcareous creatures found fossilized in deep-sea sediments, triggering a revolution in understanding ice-age cycles and provided a basis for palaeoclimatology. He was also an avid clarinetist and taught a course on the physics of music.
