A spectrum-matching and look-up-table (LUT) methodology has been developed and evaluated to extract environmental information from remotely sensed hyperspectral imagery. The LUT methodology works as follows. First, a database of remote-sensing reflectance (R[subscript]rs) spectra corresponding to various water depths, bottom reflectance spectra, and water-column inherent optical properties (IOPs) is constructed...
NASA’s ICESat-2 satellite, which launched in 2018, carries the Advanced Topographic Laser Altimeter System (ATLAS), a green-wavelength, photon-counting lidar. While ICESat-2’s primary mission focuses on measurement of elevation of ice sheets, glaciers, sea ice, and vegetation, ATLAS has also proven remarkably effective at measurement of bathymetry, or water depths. However,...
These are the proceedings of the fifth short course in managing young forests in the Douglas-fir region, conducted by the School of Forestry, Oregon State University, June 11-13, 1973.
Knowledge and experience in the management of young forests continues to expand. The short courses are designed to keep pace with...
Transcriptome and genome data from twenty stony coral species and a selection of reference bilaterians were studied to elucidate coral evolutionary history. We identified genes that encode the proteins responsible for the precipitation and aggregation of the aragonite skeleton on which the organisms live, and revealed a network of environmental...
