Many publications, documents, codes and guidelines exist related to the seismic evaluation and rehabilitation design of existing buildings. This report discusses the assumptions and methods employed for investigation of ...

Multibeam sonar data was collected on Nehalem Bank, off of the Oregon Coast with the purpose of increasing the spatial resolution of our knowledge of the area and delineating seafloor habitats. The system used was the Ko ...

Seismic properties (P, S velocities and Poisson's ratio) of young (0.75 m.y.) and mature (110 m.y.) oceanic crust are obtained by studying explosive refraction data collected in the Pacific Ocean using ocean bottom an ...

Snags (standing dead trees) are an essential structural component of forests. Because wildlife use of snags depends on size and decay stage, snag density estimation without any information about snag quality attributes ...

Marine and terrestrial ecologists rarely exchange information, yet comparing research from both sides of the land–sea boundary holds great potential for improving our understanding of ecological processes. For example, ...

Here, liquid water path (LWP), cloud fraction, cloud top height, and cloud base height retrieved by a suite of A-train satellite instruments (the CPR aboard CloudSat, CALIOP aboard CALIPSO, and MODIS aboard Aqua) are com ...

One of the challenges often faced in forestry is the estimation of forest attributes for smaller areas of interest within a larger population. Small-area estimation (SAE) is a set of techniques well suited to estimation ...
