Storm Watch over USA with Stream Flood Status

Below you should see interactive map with active hurricane tracking over USA (Atlantic and Pacific). Also Weather Radar with current precipitation, next several days flooding outlook areas. Different color square markers indicate major river flood status with links to USGS site showing up-to-date water level and projected flooding. Purple squares - major flooding on-going.

How to convert conductivity to resistivity?

Electrical resistivity (ER) is reciprocal to conductivity (EC) and results can be easily recalculated using formula EC=1/ER or vice versa ER=1/EC. Electrical resistivity is more convenient to use on non-saline soils, where conductivity can be mSm/m, while resitivity measures in 102-103 Ohm m range. 1000 Ohm m equals 1 mSm/m. You can find more conversions to ppm, TDS, grains of salt in this flyer.

Agricultural Geophysics Webinar Series: "Application of Geophysical Methods to Agriculture: Methods Employed"

A live webinar on the application of geophysics to agriculture will be offered on:

Tuesday, February 18, 2014, from 3pm - 4:30pm EST
(2:00 - 3:30 CST, 1:00 - 2:30 MST, 12:00 - 1:30 PST)

This first in a series of agricultural geophysics webinars will focus on the near-surface geophysical methods presently being used for agricultural purposes, which include resistivity, self-potential, electromagnetic induction, ground penetrating radar, dielectric sensors, VIS/NIR/MIR spectrometry, gamma ray spectrometry, mechanical soil compaction sensors, and ion selective potentiometry. Five presenters will provide a short overview of agricultural geophysical methods during the first 30 minutes of the webinar. The last hour of the webinar will be devoted to a panel discussion with the presenters, who will answer questions from the audience.
