Talk: Geophysical Data: “Real data has real warts”
Posted November 10th, 2010 by dale
I somehow let Carol Mountain (http://eesc.columbia.edu/admin/ms-carol-mountain) the undergraduate program coordinator of the Department of Earth and Environmental Science at Columbia (http://eesc.columbia.edu) talk me into giving a noon-time talk (mostly) for undergraduates in the department.
The talk announcement is here:
Summary: In spite of the rapid growth of modeling and analysis in recent decades, there remain many opportunities to gain new insights about the Earth by making measurements. In the most general sense, one can can make well understood measurements, using existing tools and techniques, in a new place or make new measurements with new instrumentation. In either case (and all the shades of grey in between) failure to understand the data can lead to misinterpretation and inappropriate use. We will take a cooks tour of a few geophysical data acquisition systems, covering the acquisition and including real-time display, quality assessment, and archiving issues. The discussion will also visit how such efforts are conceived, organized, and executed.
