Physical and Chemical Data. Piquero Expedition 16 December 1968 - 16 April 1969.
Abstract
The primary purpose of the PIQUERO Expedition was the following: (1) To obtain more data on noble gas concentrations, mainly on the excess helium component present in deep Southeast Pacific waters attributable to an influx of helium from the solid earth; (2) to conduct a sub-bottom (air gun) profiler survey of a possible extension of the Atacama Fault on the continental shelf near Taltal, Chile; (3) to study the circulation of the Chile Current between 40 degrees S and 57 degrees S and of the Antarctic Circumpolar Current in the area between Cape Horn and the Antarctic Peninsula; and (4) to study the distribution of plankton in relation to prevailing hydrographic conditions and concentrations of nutrient chemicals in coastal and oceanic waters off western South America.
