Prof.Dr. Nezihi CANITEZ Geophysical Data Processing Laboratory
Geophysical Data Processing Laboratory was established in 1996 under the sponsorship of DPT, TÜBİTAK, and MTA projects. This laboratory is the third one in Turkey following Turkish Petroleum Company and TÜBİTAK-MAM similar laboratories. ITU is one of the two universities in Turkey that owns such a facility. This laboratory serves to both graduate and undergraduate students.
Following the 1999 devastating Earthquakes in Marmara Region, this laboratory has assumed specialresponsibility of processing marine seismic and bathymetric data related to the active tectonics of the Marmara Sea.

Applied Geophysics Laboratory
The Applied Geophysics laboratory was established for the education of undergraduates and a storage place of geophysical instruments and their supplies. The field geophysics experiments have been carried out by using basic geophysical instruments belongs to this laboratory. The laboratory needs some new geophysical instruments such as 24-channel seismic recorder, gravimeter and ground penetrating radar. In addition, a large space for laboratory and spare parts of the existing geophysical instruments are necessary to achieve major geophysical engineering practices during the undergraduate education.
The laboratory was established in 1973 by the joint work between the Faculty of Mines of the Istanbul Technical University and Kandilli Observatory and called “KANTEK”. The location of laboratory is in the campus of the Kandilli Observatory and Earthquake Research Institute, Çengelköy. The main goal of this laboratory is to investigate the crustal and lithospheric scale movements in Turkey and surrounding area and understand the tectonic processes in the geologic
past by using the paleomagnetic rock samples.
Up to date, many research projects were run such as Rotation of Kırşehir Massif; Paleomagnetic properties of the Almancık Mountain; Investigation of neotectonic regime of the western Anatolia
and Thrace by the paleomagnetic studies; the neotectonic evaluation of the eastern edge of the Çankırı Basin. Also, this laboratory was used by the undergraduate students for the laboratory experiments required by their graduation project. Currently, the paleomagnetic experiments can be done on both volcanic and sedimentary rocks in the other institutes. However, the present instruments in KANTEK paleomagnetism laboratory are only appropriate for the experiments done on the volcanic rocks. Many geologic and tectonic problems can be solved by using modern instruments which are suitable for the experiments for the sedimentary rocks.
The undergraduate students can obtain the seismological data from the national (Kandilli Earthquake and Research Institute, KOERI, the Scientific and Technical Research Council of Turkey, TUBİTAK et al.) and international institutions (USGS-NEIC, ISC, Harvard-CMT, IRIS, ORFEUS, ERI-Tokyo et al.). By using these compiled earthquake data catalogues and digital wave forms, the undergraduate students mainly work on the problems of seismotectonics and seismicity. There are a few seismological instruments (microtremor, strong motion, and broad-band 3 component seismometer) in the laboratory obtained from the research projects. The infrastructure of the laboratory was renewed.
Computational Geophysics Laboratory
A high performance computing system is delivered and the infrastucture studies are in progress. The project to establish this laboratory has been initiated by Dr. Ayşe Kaşlılar in 2008. The project is supported by Shell Co. and partly by ITU Scientific Research Funds. This initiative is appreciated by Dr. Özdoğan (Oz) Yılmaz, the CEO of Anatolian Geophysical Co., and he also donated a second high performance computing system to the laboratory. Both systems are specially designed for High-Performance Computational (HPC) tasks running under the Linux operating system.
This laboratory will be the first example in a Geophysical Engineering Department in Turkey. Both graduate and undergraduate students will benefit from this laboratory during 2D and 3D modeling of wave phenomena and code development for forward and inverse solutions in geophysics. Moreover, the laboratory will be used by other research groups studying subsurface imaging at scales ranging from meters to whole-Earth dimensions.
