Archaeologists and remote sensing specialists around the world rely on GSSI ground penetrating radar (GPR) as a key tool for non-invasive site investigation. As a geologist or archeologist, how can you identify resources without sampling or disturbing surfaces? Our own geophysical survey reports are accessible online via Research Reports. Geophysical survey is the systematic collection of geophysical data for spatial studies. J. M. Leigh Surveys Ltd. is an independent geophysical survey consultancy, specialising in surveys for archaeological projects. We carry out surveys on behalf of archaeological units, consultants, engineering/construction companies, local government, individuals, etc. Archaeology & Geophysical Surveys SUMO Geophysics for Archaeology & Engineering is the largest provider of archaeological geophysics in the UK. Geophysical Survey in Archaeological Field Evaluation . We offer a range of geophysical techniques, which can be employed individually or together depending on site specific factors. A radio signal is transmitted and received, recording reflections from sub-surface features and objects. Archaeological geophysical survey of land at Whittlesey Road, Thorney, Peterborough May 2011. Information on commonly used geophysical techniques in shallow water surveying and guidance on the acquisition, processing and interpretation of geophysical data for the assessment of the archaeological potential of the marine environment. See our extensive range of expert advice to help you care for and protect historic places. Geophysical Survey Geophysical surveys are often required ahead of development as part of the planning process. Instrumentation. Please contact: [email protected]  for information and training. Our surveys are related to the Ordnance Survey National Grid using global positioning systems (GPS) with real-time kinematic (RTK) corrections typically providing 10mm accuracy. Geophysical survey offers a rapid non-intrusive but not wholly reliable method of detecting potential sub-surface archaeology. The data is most commonly collected by a fluxgate gradiometer. Find out about services offered by Historic England for funding, planning, education and research, as well as training and skill development. Our geophysical survey service specialises in identifying potential archaeological deposits. SUMO Services Ltd were commissioned to undertake a geophysical survey of an area outlined for development. The technique is used to map below surface features and allows speedy assessment of archaeological site potential and effective targeting of further investigations. With over 20 years of experience in conducting, managing and interpreting field data we provide a concise and complete geophysical service for both small and large scale projects throughout Ireland. GEOPHYSICAL SURVEY. However, the Geophysics Team can advise on survey considerations. For advice or to use our services contact: Magnetometer survey of a Roman settlement and a modern service pipe, Magnetometer survey of a prehistoric enclosure settlement, Ground-penetrating radar survey of a chambered tomb, Student Complaints and Non-Academic Misconduct, Pre-development investigations for residential, commercial and public developments, Pre-development investigations for road, pipeline, renewable energy and other infrastructure schemes across the UK, Park and garden surveys for historic landscape projects, National and international heritage management projects. Geophysical survey is a cost-effective, non-intrusive and relatively quick way of detecting and assessing sub-surface features. A copy should also be lodged with the relevant local Historic Environment Record (HER) in their preferred format. John Laing Collection JLP01/08/007475, New Heritage Partnership Agreement Signed at King's Cross Station, Brixton Windmill - Friends of Brixton Windmill. Grid Nine Geophysics were commissioned by the Bingham Heritage Trails Association (BHTA) to carry out a detailed magnetic and resistance survey of part of the Deserted Medieval Village in Crow Close. The main methods of geophysical survey are magnetometry and resistivity although a number of other techniques such as … Magnetometer survey Magnetometer survey offers the most rapid ground coverage and records a variety of anomalies caused by past human activity. Electrical resistance survey of an archaeological site using a twin probe system. Much of our advice is summarised in the EAC Guidelines for the Use of Geophysics in Archaeology which are available as a free PDF download. Techniques include magnetometry, resistivity, magnetic susceptibility and ground penetrating radar, each having a particular strength dependent on the underlying geology, soil conditions and feature type. We aren’t planning to produce a new version of this guidance at the moment. Read about our current news, projects and campaigns nationally and in your area. We are considering the need for new guidance specific to England in light of the recent publication of Europe-wide EAC guidance but we have no firm plan to produce updated guidance at this time (June 2018). Find out about listed buildings and other protected sites, and search the National Heritage List for England (NHLE). We offer a range of geophysical techniques, which can be employed individually or together depending on site specific factors. Geophysical survey is a cost-effective, non-intrusive and relatively quick way of detecting and assessing sub-surface features. Various forms of geophysical survey can be undertaken, including Magnetometer, Earth Resistance and Ground Penetrating Radar, all of which are non-intrusive. How can you detect buried features in difficult-to-reach areas, or without excavation? Copies of the 2006 guidance document are available on request to [email protected]. On 1st April 2015 the Historic Buildings and Monuments Commission for England changed its common name from English Heritage to Historic England. We provide a variety of geophysical techniques enabling time, cost effective, non-invasive survey for archaeology, utility detection and geotechnical investigation. A timely Geophysics Survey can provide a clearer picture of both known and potential archaeology on a site, detailing factors such as the extent, nature and form of various below ground archaeology features. If you need an archaeological survey, geophysical survey or archaeological evaluation for a development site, or require a heritage impact assessment or heritage statement for your planning application, we provide a range of comprehensive heritage assessment reports and archaeological services tailored to meet your needs. Because geophysical surveys are non-destructive they are often favoured by planning archaeologists as useful tools in assessing the potential of a site, particularly ‘green field’ developments. Geophysical survey represents a cost-effective approach to evaluation and is often a first step in archaeological fieldwork. Survey is followed by specialist analysis and interpretation of the data. These methods are neither invasive nor destructive, an important goal when surveying culturally sensitive sites such as cemeteries. Otherwise, we'll assume you're OK to continue. Detection and analysis of the geophysical signals forms the core of Geophysical signal processing. You can change your cookie settings at any time. Geophysical surveysare archaeological methods that use ground-based physical sensing techniques to produce a detail image or map of an area. Shortlisted for ‘Best Rescue of an Industrial Building or Site’ Angel Award in 2012, Michaela Strivens: Upside down world, Wallington, London Suburbs, Caesium magnetometer towed array in use at Charlton, Looking After Parks, Gardens and Landscapes, Improving Access to Historic Buildings and Landscapes, Materials Science and Industrial Processes, Read about our latest aerial investigation methods.
