    Description: Designing and establishment ISO/IEC17025 in IFRO and related research centers (Bushehr, Sari, Bandar Abbas ) is of interest from both research programs and improved research services . This project has been conducted for the first time in ISRC at Bushehr province by co-operation of IFRO and IGX Co from 2007 to 2010. The aim of this study was to investigate the establishment of ISO/IEC17025 in test laboratories . . Establishment of ISO/IEC17025 has been done in three stages . In first step gap analysis of laboratories was done .In second step training courses for laboratories staffs and different type of procedures was compiled . Review of documents , internal auditing training course and internal auditing activity of laboratories was also done and applied to laboratory conformity . In present study laboratory facilities has completed including: sandwich panel partitioning whit coated electrostatic 10 cm diameter , 147.68 m 2 ( square meter ) and also one way door whit slit slot 9 , cabinets 30 m2 ( square meter ) , mechanical and electrical affairs , laboratories equipments19 unit : micro centrifuge , hydrometers , bougarof lam , sampling bottles , plankton nets , digital autoclave , friseur , refrigerators , on the job training courses 5 ,QM(1) , Instructor procedures (21) , test method instructors(9) , sampling instructors (4) , technical equipment instructors ( 21) , and 50 forms and lists . The system has been audited during summer 2009 in a laboratory site located Bahmany area, Bushehr. The audit has worked out well and result show that no serious operational problems have accrued. Results also showed that QMS was successfully achieved ISO/IEC17025 accreditation by the IAS( Iran accreditation system) for three laboratories named , molecular genetics , pathology and plankton . Here we also found that accurate approaches for useful to more study of the other laboratories of ISRC and have the potential to provide long term data sets.

    Description: The rising demand for potable water in densely populated coastal regions has recently promoted growing research interest in detecting offshore freshened groundwater (OFG) worldwide. Recent geophysical studies along the continental margins offshore Israel, New Zealand, Malta, and the United States of America provide some examples of integrating geophysical and borehole data to constrain the spatial extent of OFGs and estimate their pore-water salinity. However, occurrences of OFGs and the interaction between terrestrial, carbonate-hosted groundwater systems with seawater are understudied in many coastal regions by complicated seafloor morphology. In this study, we investigate whether OFG can exist offshore a semi-arid carbonate coastline along the Maltese Islands and explore the possibility of sustainably exploiting these reservoirs as an unconventional source of potable water to relieve freshwater scarcity. We present an integration of 2-D resistivity models derived from marine controlled source electromagnetic (CSEM) measurements with 2-D and 3-D seismic data, core samples, borehole data, and geochemical measurements. Electrical resistivity models identify localized resistive anomalies (〉 10 ohm-m) offshore the northeastern coast of Gozo (the second-largest island in the Maltese archipelago). Furthermore, a resistive body is observed at ~ 300 m below sea level close to the coast of Gozo which extends northeastwards and disappears at ~ 8 km offshore. If the anomalous resistive body is associated with pore-water salinity variations or, alternatively, caused by lithological changes, will be discussed through an integrative geological model developed along each profile.

    Description: play significant roles in coastal hydrologic systems. Despite the importance of these offshore groundwater systems and their interactions with onshore systems along global coastlines, a lack of understanding persists due to limitations in geophysical methodologies. Controlled-source electromagnetic (CSEM) techniques are one promising noninvasive avenue for identifying and characterizing OFG and SGD. However, the current availability of CSEM systems in academic research is limited, and applications are still restricted to specific regions. Existing CSEM systems are commonly associated with high deployment costs, logistical complexity, limited modification options and in case of seafloor-towed applications, slow data acquisition rates. To address these limitations, we introduce SWAN - a low-cost, modular, surface-towed hybrid time-frequency domain CSEM system capable of detecting OFG and SGD up to water depths of 100 m. A field test conducted in the central Adriatic Sea showcased the system's capabilities at water depths ranging from several tens to approximately 160 m. SWAN's ability to provide continuous measurements has proven effective in acquiring high-quality data while operating at towing speeds of 2.5 to 3 knots. The system's data coverage allows for the detection of subsurface resistivity variations to depths of approximately 150–200 m below the seafloor. With its user-friendly, modular design, SWAN offers a cost-efficient solution for investigating the hydrogeology of shallow offshore environments. The presentation shows the technological developments of SWAN, including illustrations of measured time series, processed data and first 2D inversion results from the Adriatic Sea.
