DCR data were gathered and an electrical tomography section was recovered using conventional four-electrode instruments with a Schlumberger array and a two-dimensional (2D) inversion scheme. The proposed scheme was tested over a synthetic threedimensional (3D) subsurface model before deploying it in a field situation. The proposed method indicated that gathering data with simple four-electrode instruments at stations along a line and 2D inversion of datasets at multiple stations can recover depth intervals of the studied aquifer in the hydrogeological setting even if it has a 3D structure. In this study, 2D inversion of parallel profiles formed a pseudo-3D volume of the subsurface resistivity structures and mapped out multiple resistive (>25 ohm•m) bodies at shallow (between 50-100 m) and deep sections (>150 m). In general, the proposed method is convenient to encounter geological units that have limited vertical and spatial extensions in any direction and presents resistivity contrast from groundwater-bearing geologic materials.

High demand for some rare gems creates pressure on the production line and some gems are consumed... more High demand for some rare gems creates pressure on the production line and some gems are consumed quickly in some countries. In order to sustain the gem supply to the most demanding markets, man-made minerals may be considered as an alternative to expensive genuine ones. Non-genuine precious and semiprecious stones can be found as enhanced, reproduced, and counterfeited gems. The former is extremely common among precious gems, while the last one is usually for semiprecious stones. Enhancement methods transform (or recycle) very low-quality (waste) gems into unique jewelry. Fabricated crystals are obtained (or recycled) from different or even irrelevant materials. The identification of such materials is getting harder due to continuous improvement in production technologies. Governing bodies have begun to issue regulations to their members so that misleading information given in retail can be reduced. In addition to limited regulation and enforcement, the buyers will also need some sort of education provided by trustworthy foundations such as reputable labs, mineral museums, and academic institutions. Although the internet provides a vast amount of information about fake minerals, most of which is also fictitious, especially, earth science-related museums should have a special duty in this regard and educate the public through hands-on experiments.

The base unit of this structure, which is about 20 meters off the shoreline at 2 meters water depth, is perfectly preserved up to the present. Archaeological research has argued that this structure has been collapsed due to the devastating AD740 earthquake. On the other hand, the existence of beachrock beds on the surveyed beach (near the protected area), which is just a few meters away from the basilica, makes an alternative interpretation possible. Beachrocks with broad distribution throughout the Lake İznik keep records of the climate changes in the late Holocene. Considering that the water level of the lake descended to 2 meters during arid periods, as supported by existing multiproxy data obtained from the sediment cores taken from the lake, existence of beachrock beds in the surveyed beach allows to think that beachrock may exists in the basilica area. In this case, if the basilica was built on beachrock beds, providing a hard and safe ground for the construction, then it may have been inundated due to rise of lake waters during the following rainy stage. This study was conducted to test the hypothesis briefly described above. Geoelectrical measurements were made using the Electrical Resistivity Tomography (ERT) method at the public beach located just 10 meters from the basilica. Beachrock beds (strike N10°E., dip 5°NW) crops in out in a limited area on the beach where the survey section was taken. ERT section was taken perpendicular to the shoreline to determine subsurface extension, thickness and the angle of dip of the buried beachrock beds as well as the existence of possible earthquake-related deformations. Our preliminary findings reveal that the measured values on resistivity values delineated the two distinct; beachrock units (>100ohm) and altered zones (100ohm<). The tomographic image shows that the beds which seem to have buried 50 cm below the surface have resistivity values over 120 ohm.m and have average dip at an angle of 10° towards the lake (i.e westward). The thickness of the buried sandstone is 1 meters. The fact that the beds are regularly inclined towards the lake, with no evidence for tectonic deformation, raise doubts about the impact of the AD740 earthquake on the collapse of the basilica. In addition, no significant deformation is observed in the underwater images of the basilica walls. In this case, if the geophysical surveys are conducted along the beach behind the basilica and if the beachrock beds are found below this underwater structure are determined, it is highly probable to obtain evidence confirming our hyphothesis.

Along the ground rupture, which cuts the beachrock beds (strike N60°E., dip 5°NW) with visible thickness of 50 cm, beds are tilted to the southeast at a maximum angle of 40°. The tilted block dated to 1.332 ± 0.145 ka by optically stimulated luminescence (OSL), is overlain by a younger generation of beachrock with an OSL age of 1.188 ± 0.096ka. In this study, the Electrical Resistivity Tomography (ERT) method was used to detect the subsurface structure of this ground rupture caused by the dectructive historical AD740 earthquake. The resistivity tomogram taken perpendicular to the shoreline allowed to observe vertical component of rupture at depth range of 3 m. Massive beachrock covers the area and a possible fault whose location is 3 to 5 m to the shoreline, observed between 16 to 18m. The tomographic image explains that values over 120 ohm.m refer to carbonate-cemented hard-bedrock beds with buried thickness of 1 m, containing gravels and sands derived from chert, limestone, marble and volcanics. The lower boundary of beachrock beds shows a clear tilting again backwards with an angle of 10 degrees or more.

Bu gerilim doğal veya yapay kaynaklı olabilir. Oluşan gerilim mili Volt ve altı düzeylerinde ise bu gerilim farkını ölçebilmek için Uçlaşmayan (polarize) olmayan elektrotlar gereklidir. Bu çalışmada, mikro voltaj düzeyindeki ölçümler için başta kurşun-kurşun klorür ve bakır bakır klorür içerikli olmak üzere farklı türde elektrotların üretilmesi amaçlanmıştır. Elektrotlar için farklı çap ve boyda deneme modelleri hazırlanmıştır. Elektrotların gerek laboratuvar ortamında gerekse alan çalışmalarından elde edilen sonuçlar bu çalışmada sunulmuştur. ABSTRACT Geophysical methods are used to measure the ionospheric movements that occur underground in the natural flotation method and to measure the resulting voltage difference. This tension can be natural or artificial. Non-polarized electrodes are required to measure this voltage difference when the resulting voltage is at the Volt or below. In this work, it is aimed to produce different types of electrodes, especially lead-lead chloride and copper copper chloride, for measurements at the micro voltage level. Experimental models have been prepared for different diameters and lengths for electrodes. The results obtained from both the laboratory and field studies of the electrodes are presented in this study.

The Departments of Geomatics Engineering, Geological Engineering, Geophysics Engineeringand Geography Educationof Canakkale Onsekiz Mart University have collaborated with the goal of exploring the conditions leading to dense earthquake activity throughout Ayvacık, Canakkale and surrounding area with the hope of mitigating seismic hazard and damage.The deformation rate exceeds to the highestlevel during and directly after the earthquake and then decreases with time, and depends partly on the rate of aftershock activity. The project team has deployed 9 GPS/GNSS sites around the causative Tuzla,Kocaköy and Babakale Faults, respectively, in order to measure the months-long relaxation of the crust (post-seismic deformation) after the February earthquake.The geology of the region is generally composed of the andesite, ignimbrite and tuff exposed from the volcanismoccurred in Miocene.Site selectionwas undertaken at the beginning of theApril, 2017 by investigators from thedepartmentsmentioned above.Sites were selected based on earthquake intensity map that showed earthquake induced horizontal and vertical deformation. Sites were located in areas of the expected vertical deformation as well as at horizontal intervals from the faults in order to measure relaxation on both block (foot and hanging walls) of the faults. Establishing GPS/GNSSsites in places quickly enough to record the post-earthquake deformation signal isa priority. Biga peninsula, which houses earthquake swarm zone, is one of the less studied areas of the western Anatolia in terms of GPS/GNSS activities. The result of the very few stations concluded that the movement of the Anatolia is switching the direction from western dominant direction to southwest dominant direction, yet, creating normal faults around Bababurnu. This outcome indicates that there may be velocity difference along the Biga peninsular. This project will provide prior information for future research work in the region concerned. Furthermore, it will help train the researchers in GPS / GNSS topics. Moreover, A GPS/GNSS network has been established that reflects the earthquake activity and fault structure in the region.The fault geometry and block structure can be modeled with the help of the obtained results from the post-seismic deformations by GPS/GNSS network.
Seismic, dc resistivity, transient electromagnetic (TEM) and audiofrequency magnetotelluric (AMT)... more Seismic, dc resistivity, transient electromagnetic (TEM) and audiofrequency magnetotelluric (AMT) methods have been jointly applied to the characterisation of a complex bedrock and overlying sedimentary rocks in an area covered by heterogeneous glacial deposits in midland England. Maps of TEM voltage response enabled a clear assessment of spatial variability and significant fracture-zones in the complex basement. The TEM sounding curves served for static shift correction of AMT data. Co-operative 2-D regularised inversion of the dc, AMT and seismic data led to concordant models of the subsurface and allowed improved determination of the basement-cover relations in the area of study.

The aim of the study is to detect aquifer boundaries of Upper Pleistocene aged shallow marine carbonates of Dardanelles Group not outcropping in the site but exposing in the surrounding of it. The modeled geo-electrical section is also examined about why the aquifer consisting of the carbonate rock formation do not outcrop and is overlaid by clastic deposits in the survey site. This allows us further and detailed hydrogeophysical surveys to detect aquifer boundaries in a more extend than the site in the view of regional geology and tectonic activity. The site is situated in the northern part of the Gelibolu Peninsula. The peninsula is covered by the sedimentary sequence of Eocene - Oligocene aged and the unconformably overlaying sedimentary sequence of Upper Miocene - Quaternary aged. The surface geology of the site and its surrounding include the sedimentary sequence of Upper Pleistocene belonging to Dardanelles Group. From bottom to top it has fluvial deposits, shallow marine carbonate and clastic deposits. The direct current resistivity method with independent soundings along a profile revealed the geo-electrical model. Evaluation of both geo-electrical model sections and the surface geology reveal a proposed geological section and the aquifer boundaries. The model indicates that: (1) the clastic deposits overlie the aquifer of shallow marine carbonate deposits as wedge shaped in the survey site, (2) the shallow marine carbonate deposits are just visualized approximately 55 m into the land regarding to the evaluation of the hydrogeophysical model, (3) a wetness front is evaluated which imply that the clastic deposits reveal perched aquifer conditions. Moreover, the shallow marine carbonate deposits outcrop in the surrounding of the survey site as marine terraces due to the regional tectonic activity and bound the survey site morphologically. This situation gives opportunities for conducting further hydrogeophysical surveys on the selected locations of the vicinity of the site to reveal what the subsurface continuity of the aquifer is in the context of the regional geology and tectonic activity.
Marine magnetotelluric measurements using “free-fall’’ instruments without effective compasses su... more Marine magnetotelluric measurements using “free-fall’’ instruments without effective compasses suffer from the problem of unknown orientation of the receivers at the seafloor. While past works indicate that marine magnetotelluric orientation of the instruments can be estimated by reference to land deployments of known orientation using the transfer tensor method, there is limited published information on how this is implemented in practice. We document this method and propose a set of new time- and frequency-domain approaches to solve this orientation problem of the seafloor receivers. We test these methodologies in onshore and offshore magnetotelluric data whose orientations are well known and apply these techniques to marine magnetotelluric data with unknown orientation. For the controlled tests, both time- and frequency-domain approaches produce overall comparable results. To investigate the effects of the subsurface structure distribution on the orientation process, a dimensionality analysis of a controlled dataset is carried out. In subsequent analysis using the available disoriented marine magnetotelluric data from offshore Brazil and from the Vassouras magnetic observatory on the mainland for remote referencing, frequency-domain methods yield approximate orientation angles among themselves with low standard deviation each. Time-domain results are consistent for most cases but differ from frequency-domain results for some situations.

Our effort to seeking solution to solution to some of the problems, e.g., on selecting development model, on deciding to structural architecture and on maintenance of the web site and museum itself provide some real-life experience that could be taken as a reference to develop similar applications for both academic and non-academic purposes for even presenting site-specific artifacts or products in developing countries. Visiting statistic pointed out that number of visitor is reciprocal to display technologies. The more static the exhibition environment is, the less attractive it becomes. Web applications are the recent technology that can be adapted to conventional museum and convey vast amount of the information to the visitors and help them to digest it much effectively. A prototype web application, which uses QR code to access predefined web sites, has been developed and tested in our museum. Both animation and web based additional information from well-established web sites are used wherever possible to improve the technicality and attractiveness of the displays. Overall test results indicate that the application is successful.
