"Humboldt and Bonpland studied the meteorological phenomena, physical geography, and the ancient and modern cultures of the regions they explored. At Callao, Humboldt measured the temperatures of the ocean current which came to bear his name. He also made investigations into the properties of guano, which ultimately led to its export to Europe. He used scientific instruments for a continuous survey in orography, meteorology and earth magnetism. Bonpland studied plant life in its environmental conditions and collected about 60,000 specimens, among them thousands of new species and genera" (Hill).
