The Volcanic Dust of Barbadoes, 1812

Sun/dust correlations and volcanic interference

[1] We examine the relationship between the GISP2 dust profile, a proxy for the Northern Hemisphere atmospheric dust load, and the Wolf sunspot number, a proxy for solar activity. The two records are positively correlated, but the phase of the relationship is disturbed by the effects of explosive volcanism. Similar correlation failures have already been noted for many other climatic indicators....

Jovian Dust Streams: A monitor of Io’s volcanic plume activity

Streams of high speed dust particles originate from Jupiter’s innermost Galilean moon Io. After release from Io, the particles collect electric charges in the Io plasma torus, gain energy from the co-rotating electric field of Jupiter’s magnetosphere, and leave the Jovian system into interplanetary space with escape speeds over 200 km s. Galileo, which was the first orbiter spacecraft of Jupite...

Dust in the wind: How climate variables and volcanic dust affect rates of tooth wear in Central American howling monkeys.

OBJECTIVES Two factors have been considered important contributors to tooth wear: dietary abrasives in plant foods themselves and mineral particles adhering to ingested food. Each factor limits the functional life of teeth. Cross-population studies of wear rates in a single species living in different habitats may point to the relative contributions of each factor. MATERIALS AND METHODS We ex...
