Best Practices in Earth Sciences: The National and International Experience of the Institute of Geophysics, Polish Academy of Sciences
The Institute of Geophysics of the Polish Academy of Sciences is the natural successor to the glorious tradition of geophysical research in Poland. It plays the leading role in exploration of the Earth, beginning from the atmosphere across hydrosphere to the lithosphere at the end. This chapter is prepared on the occasion of the 60th anniversary of establishment of this Institution and it shows its activities in the past and nowadays.
Sixty Years of Publishing with the Institute of Geophysics
The main publications written by people associated with the Institute of Geophysics PAS are outlined. Presently, the major titles are Acta Geophysica and the GeoPlanet Book Series. The journal Acta Geophysica, formerly Acta Geophysica Polonica, is of the same age as the Institute. The GeoPlanet Book Series evolved from Monographic Volumes of the Publications of the Institute of Geophysics. Also many significant, pioneering monographs are recalled, along with some remarks on the Institute’s history.
Geomagnetic Polarity Epochs: Sierra Nevada Data, 3
Available paleomagnetic and radiometric results for about 60 igneous rocks 3.6 m.y. old or less are consistent with the following geomagnetic polarity epoch time scale: Brunhes normal polarity epoch, 0.0 to 0.85±0.15 million years; Matuyama reversed polarity epoch, 0.85±0.15 to 2.4±0.1 million years; Gauss normal polarity epoch, 2.4±0.1 to 3.35±0.1 million years; Gilbert reversed polarity epoch, 3.35±0.1 million years to (?). A brief interval of normal polarity (the Olduvai event) occurs within the Matuyama reversed epoch at about 1.9 m.y., and a brief interval of reversed polarity (the Mammoth event) occurs within the Gauss normal epoch at about 3.06 m.y. Data for twelve units from eastern California and Nevada, reported here for the first time, are particularly useful in defining the Gauss-Gilbert boundary and for recognizing the Mammoth event.
