Quantifying ice cliff evolution with multi-temporal point clouds on the debris-covered Khumbu Glacier, Nepal
Measurements of glacier ice cliff evolution are sparse, but where they do exist, they indicate that such areas of exposed ice contribute a disproportionate amount of melt to the glacier ablation budget. We used Structure from Motion photogrammetry with Multi-View Stereo to derive 3-D point clouds for nine ice cliffs on Khumbu Glacier, Nepal (in November 2015, May 2016 and October 2016). By diff...
متن کاملSouth Cascade Glacier mass balance , 1935 – 2006
A simple model uses daily observations of precipitation and temperature at a nearby weather station to estimate glacier-average seasonal mass-balance components at South Cascade Glacier, Washington, USA, from 1935, 24 years before measurements began at the glacier. This is 13 years earlier than measurements that can be derived using the NCEP–NCAR reanalysis database (begins 1 January 1948). Alt...
متن کاملThe Mass Budget of Merging Quasars
Two spectacular results emerging from recent studies of nearby dead quasars and distant active quasars are (i) the existence of tight relations between the masses of black holes (BHs) and the properties of their host galaxies (spheroid luminosity or velocity dispersion, galaxy mass), and (ii) a consistency between the local mass density in BHs and that expected by summing up the light received ...
متن کاملLinking glacier annual mass balance and glacier albedo retrieved from MODIS data
Albedo is one of the variables controlling the mass balance of temperate glaciers. Multispectral imagers, such as MODerate Imaging Spectroradiometer (MODIS) on board the TERRA and AQUA satellites, provide a means to monitor glacier surface albedo. In this study, different methods to retrieve broadband glacier surface albedo from MODIS data are compared. The effect of multiple reflections due to...
متن کاملThe Galactic disk mass - budget : II . Brown
In this paper, we extend the calculations conducted previously in the stellar regime (Chabrier, 2001) to determine the brown dwarf initial mass function in the Galactic disk. We perform Monte Carlo calculations taking into account the brown dwarf formation rate, spatial distribution and binary fraction. Comparison with existing surveys seems to exclude a power-law mass function as steep as the ...
