Abstract:

The report covers operation and research activities at the Norwegian Seismic Array NORSAR in the period 1 January-31 March 1975. Both for the field and data center installations this has been a stable period. Two studies of scattering in the crust and upper mantle and one study of scattering in the mantle-core boundary have been finished. A Kirnos verticle broadband instrument has been operated at the subarray 04B over a period of about nine months, and the results from this project are now available.
