Description: | "1 of a set of 5 large charts showing altogether the declination, inclination, horizontal intensity, vertical intensity and total intensity of the Earth's magnetic field at mean sea level at the beginning of 1985. This set of charts is for the US, with Alaska printed on the reverse. The charts are based on the International Geomagnetic Reference Field main field model for 1985 and secular change model for 1985 - 1990. By Norman W. Peddie and Audronis K. Zunde. Sold through the US Geological Survey. The charts relate to both geomagnetism research and upper atmosphere research in the Department of Natural Philosophy. d) Vertical Intensity Chart. Red contours are magnetic field intensity in thousands of nanoteslas (i.e. microteslas); blue contours estimate rate of change in nanoteslas per year." | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1988 | Source: | University of Aberdeen | Creator: | USGS | Identifier: | http://calms.abdn.ac.uk/Geology/dserve.e... | Go to resource |
