Polish Seismological Network 2004

Polish Seismological Stations maintained by the Institute of Geophysics, Polish Academy of Sciences.

Staff at IGF-PAS Warsaw site:

Other network operators in Poland working for industry:
    - Central Institute of Mining, 14 SP sites in Upper Silesia
    - Coal Mines in Upper Silesia - about 20 networks of 6-16 SP sensors each
    - Copper Mines in Lubin area - 3 networks of about 30 SP sensors each
    - Belchatow Brown Coal mine - network of 8 SP sensors

Broadband sites:

Continuous broadband data from these stations are transmitted to IGF-PAS central site at Warsaw and made available by seedlink - to international centers and seismological centers of neighbor countries as a rule, other parties upon consideration.
The same data - with exception of OJC - should be available by autodrm@igf.edu.pl with 1 day delay, however nobody uses this method and we have no control if it indeed works.
Continuous broadband data is stored on network attached storage - copies of the data made on CDROM. High sampling detected data - whenever available - are stored at the stations on CDROM.
Data format is miniseed in case of STS-2 (and formerly BB-13) data; digital data from other sensors use the MSS-format which is used only in Poland.

WAR Warszawa (Warsaw), 52.2417N, 21.0236E, 110 m
    Observatory exists since 1939; digital recording started 1996/07/15 on BB-13s
    Since 2001; STS-2+MK-6 DAS (24-bit), continuous 20 Hz, transmitted NRT to IGF-PAS
    Station is noisy due to its location in the city.

    STS-2+MK-6 DAS (24-bit), continuous 20 Hz, transmitted NRT to IGF-PAS
    100 Hz detected data available on demand.
    Station in relatively noisy especially during day.
    1997-1999 existed a temporary broadband site at CZA, 20 km from GKP

KSP Książ, 50.8428N, 16.2931E, 353 m
    Observatory exists since 1971; digital recording started 1997 on BB-13s
    1990-1992 intermittently within GSETT-2
    STS-2+MK-6 DAS (24-bit), continuous 20 Hz, transmitted NRT to IGF-PAS
    100 Hz detected data analyzed on site - mostly Lubin area induced events
    GS-13 recording in parallel; analogue paper recording off KIRNOS and SM-3
    3 staff; kspobs@igf.edu.pl

OJC Ojców, 50.2195N, 19.7984E, 391 m
    Observatory exists since 1991 - replacing the former site of KRA;
    digital recording since 1992 (triggered SP), continuous broadband since
    August, 1999.
    STS-2+MK-6 DAS (24-bit), continuous 20 Hz, transmitted NRT to IGF-PAS
    100 Hz detected data analyzed on site - mostly Upper Silesian induced events
    GS-13 recording in parallel; analogue paper recording off SM-3
    Additional torsional (SP) seismometers
    4 staff, analyzes also data from NIE station; nlkozlak@cyf-kr.edu.pl
    Observatory named after Maurycy Pius Rudzki (1862-1916), pioneer of Polish Geophysics.

Short period sites:

Short period data is analyzed and stored either on site (at RAC) or at OJC (in case of NIE). On-demand data access is possible in case of RAC.

RAC Racibórz, 50.0833N, 18.1942E, 209 m
    Observatory exists since 1928 (erected by German prof. Karl Mainka)
    Original 6 filial stations either handed over to the Central Institute
    of Mining or discontinued after World War 2.
    Digital since 1999.
    SM-3+MK-5 DAS (16-bit), triggered 100 Hz, analyzed on site
    KIRNOS recording at 20 Hz in parallel, analyzed on site
    Analogue SM-3 and KIRNOS recording on paper
    2 staff; w.wojtak@wp.pl

NIE Niedzica, 49.4189N, 20.3131E, 649 m
    Observatory exists since 1970 - until 1992 at another site about 1 km away
    Digital since 1996 but the early MK-2 DAS (used until 2002) gave very few detections
    SM-3+MK-5 DAS (16-bit), triggered 100 Hz, analyzed at OJC
    Data transferred to OJC on ZIP floppies; no internet connection
    Two extra vertical sensors at both ends of dam on Dunajec River
    Analogue recording on paper
    Dam has a hydroelectric power plant working in peak hours, therefore
    noise level varies greatly.
    1 part-time staff to change papers

Non-PLSN site:

Institute of Geophysics, Polish Academy of Sciences maintains a 7-site, 11-sensor (5 sites only vertical component) local network at its polar base at Hornsund, Svalbard. The Svalbard site is however maintained not by the Department of Seismology but by the Department of Polar Research; therefore its does not belong to the PLSN Polish Seismological Network. A similar station at Arctowski station in the Antarctic has been closed after snowfall damage in mid-1990s. Data from HSP is available only from the Department of Polar Research, IGF-PAS.

HSP Hornsund, 77.0019N, 15.5436E (within 1100 m), 5-15 m
    SM-3+MK-6 DAS (24-bit), continuous 20 Hz & triggered 100 Hz, analyzed on site
