Semiannual Technical Summary, 1 January - 30 June 2004
ABSTRACT
The NOA Detection Processing system has been operated throughout the period with an uptime of 100%. A total of 2114
seismic events have been reported in the NOA monthly seismic bulletin from January through June 2004. On-line detection
processing and data recording at the NDC of ARCES and FINES data have been conducted throughout the period. Data from
the two small-aperture arrays at sites in Spitsbergen and Apatity, Kola Peninsula, as well as the Hagfors array in Sweden, have
also been recorded and processed. Processing statistics for the arrays for the reporting period are given. A summary of the
activities at the Norwegian NDC and relating to field installations during the reporting period is provided in Section 4. Norway
is now contributing primary station data from two seismic arrays: NOA(PS27) and ARCES (PS28) one auxiliary seismic array
SPITS (AS72) and one auxiliary three-component station (JMIC). These data are being provided to the IDC via the global
communications infrastructure (OCI). Continuous data from the three arrays are in addition being transmitted to the US NDC.
The performance of the data transmission to the US NDC has been satisfactory during the reporting period.
