A method for rescaling humidity sensors at temperatures well below freezing
Read more of: A method for rescaling humidity sensors at temperatures well below freezingA method for extending the calibrated temperature rang of a solid-state capacitive humidity sensor is presented. This technique is applicable to relative humidity instruments that are based around solid-state sensors.

Long-term changes in the acid and salt concentrations of the Greenland Ice Core Project ice core from electrical stratigraphy
Read more of: Long-term changes in the acid and salt concentrations of the Greenland Ice Core Project ice core from electrical stratigraphyContinuous electrical records covering a climatic cycle are presented for the Greenland Ice Core Project deep ice core from Greenland. Electrical conductivity measurement (ECM) measures the acid content of the […]

The association of polar mesosphere summer echo layers with tidal modes
Read more of: The association of polar mesosphere summer echo layers with tidal modesThe occurrence of PMSEs with time of day shows a semi-diurnal variation with minima at 8 and 20 h LT. PMSE layers observed for more than 30 min show an […]

Galena lead isotopic variations in a Mesozoic-Cenozoic Andean arc, Antarctic Peninsula
Read more of: Galena lead isotopic variations in a Mesozoic-Cenozoic Andean arc, Antarctic PeninsulaThe Antarctic Peninsula magmatic arc was the site of Andean-type subduction from at least Silurian times to the late Cenozoic. Hydrothermal galenas from eight localities in accretionary complex, arc volcanic […]

Peraluminous granites in NE Palmer Land, Antarctic Peninsula: early Mesozoic crustal melting in a magmatic arc
Read more of: Peraluminous granites in NE Palmer Land, Antarctic Peninsula: early Mesozoic crustal melting in a magmatic arcA suite of Early Jurassic metaluminous to strongly peraluminous granitoids occupy a rear-arc position in Palmer Land, Antarctic Peninsula with respect to a Mesozoic–Cenozoic magmatic arc. Fractional crystallization of a […]
