Rock Varnish on HuaHilai and Mauna Kea Volcanoes, Hawai'i
Tropical rock varnishes found on Hualalai and Mauna Kea Volcanoes, Hawai'i, vary systematically with time and environment. Radiocarbon dating of encapsulated organic matter, (K+ + Ca2+)/Ti4+ ratios, and Zn, Cu, and Ni trace element concentrations in rock varnish are consistent with lava flowages established by K-Ar and 14C dating, where samples are collected from arid microsites well away from ...
متن کاملThe Mauna Kea Observatories Near - Infrared Filter Set . III
The isophotal wavelengths, flux densities, and AB magnitudes for Vega (α Lyr) are presented for the Mauna Kea Observatories near-infrared filter set. We show that the near-infrared absolute calibration for Vega determined by Co-hen et al. and Mégessier are consistent within the uncertainties, so that either absolute calibration may be used.
متن کاملHigh Altitude Wind Velocity at San Pedro Mártir and Mauna Kea
We analyze the monthly average wind velocity at about 12 km above sea level, between 1980 to 1995, for San Pedro Mártir, Mauna Kea, another existing observatories and some sites of interest. We compare the results obtained from two different data sets, the GGUAS and NCEP. Our results show that San Pedro Mártir and Mauna Kea are comparable and are amongst the most suitable sites to apply slow wa...
متن کاملPetrogenesis of high-CaO lavas from Mauna Kea, Hawaii: Constraints from trace element abundances
The role of a mafic component in the petrogenesis of Oceanic Island Basalts (OIBs) is highly debated. As the best studied OIB, Hawaiian lavas provide critical insights into OIB genesis. At a given MgO content, the CaO content in the melt has been used to distinguish between partial melts of peridotite and garnet pyroxenite/eclogite. However, calculations using the BATCH program show that CaO co...
متن کاملThe Mauna Kea Observatories Near - Infrared Filter Set . III . Isophotal Wavelengths and Absolute Calibration
The isophotal wavelengths, flux densities, and AB magnitudes for Vega (a Lyr) are presented for the Mauna Kea Observatories near-infrared filter set. We show that the near-infrared absolute calibrations for Vega as determined by Cohen et al. and Mégessier are consistent within the uncertainties, so that either absolute calibration can be used.
