  • Title: Archaeological Geophysical Surveys
    Descriptive info: Geophysical surveys use a variety of scientific instruments to find buried archaeological deposits.. The instruments measure small changes in the magnetic and electrical properties of the earth which can tell us where archaeology is located under the ground.. Magnetometer and Earth Resistance surveys are the most widely used techniques for archaeological prospection, however Earthsound Archaeological Geophysics offer a number of other techniques that allow for the detection of different types of features, for use in unique locations and in combination with other techniques for  ...   images from the data we gather and give an archaeological interpretation of our results.. Our reports can be supplied in hard copy or digitally for use by architects, planners, engineers, local authorities and researchers to progress and mitigate their designs and applications in a timely and cost-effective manner.. All of our surveys adhere to the industry standard Guidelines produced by English Heritage and are carried out under licence from the DOEHLG.. To discuss the use of other novel techniques for archaeological geophysics please contact us..

  • Title: Magnetometer surveys from Earthsound Archaeological Geophysics
    Descriptive info: Magnetometer surveys are the most frequently used geophysical technique in Ireland, allowing rapid mapping of magnetic anomalies contained within the sub-soil.. Many archaeological features gain a strong magnetic signature from burning and heating processes; other features such as the fill of ditches and pits gain a natural magnetism over time which can also be detected.. Magnetometer (or Magnetic Gradiometer) surveys are undertaken by hand-held machines which are carried across the survey area in a grid system.. Each  ...   local soil within the survey area, producing a map of the underlying archaeological content.. Surveys are usually conducted on a 1m line spacing with readings taken every 0.. 25m along the line; this sample resolution is often increased within research situations or where small features such as pits, post-holes or graves are thought to be located.. Magnetometer surveys are ideal for detecting:.. Hearths.. Kilns.. Burnt Mounds of Stone.. Ditches.. Pits.. Other Burnt or Fired remains.. Other geophysical techniques..

  • Title: Magnetic Susceptibility - Earthsound Archaeological Geophysics
    Descriptive info: Magnetic Susceptibility is a rapid reconnaissance technique that can provide a broad assessment of large sites identifying areas of interest to develop a detailed geophysical or excavation strategy.. Magnetic Susceptibility surveys can also be used within excavation contexts, mapping the susceptibility content of individual features, divisions or zones.. Earthsound often supplement other survey techniques, such as magnetic gradiometer investigations, with magnetic susceptibility surveys, as they are a useful indicator of archaeological trends and tell us about the ability of a soil to become  ...   soils for areas that are susceptible to a magnetic field.. The ability of a soil to become magnetised indicates environmental, geological, agricultural and, importantly for us, archaeological anomalies.. The soil is assessed in the field using a hand held device placed upon the ground surface; its susceptibility to a temporary magnetic field can be recorded digitally using a GPS, creating a basemap of potential archaeological activity.. Magnetic susceptibility is an ideal method for locating areas of:.. Burning.. Industry.. Occupation sites.. Field systems.. Soil variations..

  • Title: Ground Penetrating Radar (GPR)
    Descriptive info: Ground Penetrating Radar is a geophysical technique capable of detecting multiple buried layers at depth.. The instrument works by passing an electromagnetic pulse into the ground, which reflects off the underlying buried layers.. These reflections are digitally recorded enabling sections or plans of the archaeology to be assessed.. Multiple layers and anomalies  ...   can also be gained.. The instrumentation can be used in rural environments as well as urban areas covered in tarmac or concrete, for example under roads or within buildings.. Ground Penetrating Radar can detect a large number of possible archaeological features including:.. Voids - caves, tomb shafts etc.. Souterrains.. Masonry / Walls..

  • Title: Systematic Metal Detecting Surveys
    Descriptive info: Metal detectors are capable of detecting and identifying metallic items within the upper layers of the soil.. They are famously used by hobbyists however; all metal detector users are legally obliged to operate in Ireland only under a Detection Device licence from the government.. Metal detectors are often used as part of a recovery scheme within excavations.. However, perhaps its most valuable contribution  ...   to field assessments or field walking surveys.. Instruments can be used systematically to survey and digitally record the location of metal finds using a GPS, or to simply plot a distribution map of 'metal hits' without digging them up.. This survey can detect metallic items such as.. Nails.. Coins.. Lead Weights.. Jewelry Ð gold, silver.. Military items - musket shots, cannon, swords etc..

  • Title: Geochemical Surveys - Earthsound Archaeologica Geophysics
    Descriptive info: Geochemical surveys analyse soil samples collected from archaeological sites for subtle physical and chemical variations.. These variations can often suggest archaeological and anthropogenic activities, and complement both excavated evidence and geophysical surveys.. Geochemical analysis can be used as both a prospection tool and to further our understanding of excavated archaeological sites.. The systematic collection of topsoil samples across a survey area can identify previously unknown features and zones suggestive of archaeological remains using phosphate and magnetic susceptibility analysis.. For post-excavation research, geochemical analysis can be used to determine the possible function of a  ...   include the ability to detect refuse dumping, cess-pits, metallurgical and industrial activity, cooking sites and animal husbandry.. Geochemical soil samples can be collected by Earthsound technicians or by archaeological site staff.. Each sample needs to be collected under controlled conditions to avoid potential cross-contamination - we can advise you on how best to achieve this and which technique(s) is appropriate to answer your project requirements.. We can carry out the following laboratory analysis:.. Carbonate analysis.. Heavy Metal analysis.. Loss on Ignition analysis (organic content).. Magnetic Susceptibility content.. Particle Size analysis.. Phosphate analysis.. pH analysis..

  • Title: GPS and Topographical Surveys
    Descriptive info: Global Positioning Systems (GPS) allows accurate navigation, positioning and recording of features which are very useful for archaeology.. A GPS instrument uses a series of satellites and base stations to provide accurate sub-metre locations.. GPS surveys can be used to set-out pre-designed test trenches or area excavations as well as mapping the location of field boundaries, buildings etc.. Natural and built heritage mapping can also be achieved as well as the recording of excavated features such as open test trenches and excavation areas.. Topographical surveys within archaeology are an  ...   record, where the topography, if appreciable, can be mapped, often prior to excavation.. This record aids landscape understanding and future archaeological interpretations.. Discrete, potentially unrecorded features with a low topographical profile, such as barrows, can also be revealed.. Buried archaeological remains and changes in elevation can also be mapped.. Datasets such as aerial photographs, construction and excavation layouts can be overlaid upon topographical data, aiding understanding of the landscape.. Geophysical and Geochemical data can also be overlaid upon topographical data, providing an interactive element between topographical and geophysical anomalies..

  • Title: Cultural Resource Management Surveys
    Descriptive info: Cultural Resource Management is a combination of desk-based research and archaeological field survey.. This process may identify, record and map known or previously unrecorded archaeological monuments within rural settings and isolated landscapes.. These surveys can be used to evaluate the extent of the archaeological resource by compiling an inventory of sites and monuments, recommending conservation strategies and further investigation of selected sites.. Surveys are undertaken across several sq.. km within rugged and remote environments such as river valleys, National Parks and mountainous regions.. The archaeological resource is widespread within these settings, but largely unknown and mostly unrecorded.. Many areas have not been adequately mapped since the earliest Ordnance Survey.. Earthsound surveyors perform walk-over surveys  ...   animal pens, banks, cairns, ditches, field boundaries, hut groups, mineral extraction sites, sheep dips, trackways and ritual complexes including standing stones and stone circles are often identified in previously unknown areas of activity, achieving comprehensive mapping of the upstanding archaeological remains.. Surveys in the Welsh uplands have demonstrated that highly successful (and cost effective) archaeological assessments can map areas formerly unexplored by archaeologists: Over two years our archaeological surveys identified 418 sites and monuments, 95% of which were previously unknown, completely re-mapping the archaeological resource.. Our ongoing research at Kilcashel, County Mayo has also demonstrated a large increase in 19th century features including mill complexes and a fundamental change in field systems and agriculture..

  • Title: Research - Earthsound Archaeological Geophysics
    Descriptive info: Earthsound Archaeological Geophysics have undertaken a number of research projects over the years working with archaeological researchers and national agencies, funded by organisations such as The Heritage Council and the Royal Irish Academy:.. Site M, an Early Medieval Cemetery, at Knowth in the Boyne Valley, County Meath.. Waun Wen Upland Survey, Wales.. Templenacroha Church, County Wexford.. St.. Johns Church, Kilkenny.. Toureen Peakaun, An Early Medieval Monastic Site, Co.. Tipperary.. The Bishops Palace, Kilkenny.. Abergwesyn Common Upland Survey, Wales.. Kilkenny Castle.. Earthsound Archaeological Geophysics are currently involved in research at:.. Rathnadrinna Fort, Cashel, County Tipperary.. This project, funded by The Heritage Council, uses a series of high resolution geophysical surveys within the Rathnadrinna Fort and the surrounding landscape.. Rathnadrinna ('fort of the contest') was until recently thought to be a trivallate enclosure, measuring approximately 90m between its internal banks; it is one of several hill top enclosures surrounding Cashel.. The aim of the project is to investigate the archaeological content of Rathnadrinna Fort and its environs and to map the composition of extant earthworks.. Geophysical surveys have determined that Rathnadrinna is a quadrivallate fort and revealed the presence of an outer enclosure ditch measuring 250m in diameter.. A large number of circular ring-ditches, containing slot trenches and drip gullies also  ...   run in conjunction with local community volunteers who join us for fieldwork opportunities.. An archaeological inventory of the townland has been compiled and is complemented by a field-walking survey.. Geophysical surveys have been undertaken within Kilcashel Stone Fort revealing the presence of a number of possible structural remains, a souterrain, pits and divisional boundaries.. On the outside of the Stone Fort a possible external ditch and relict field boundaries were also identified.. You can keep up with all the latest developments on the Kilcashel website:.. www.. kilcashel.. com.. NRA Research Fellowship.. Earthsound are working with the University of Bradford and the Irish National Roads Authority (NRA) as an Industrial Partner for the NRA Fellowship award 'Preparing for the future: A reappraisal of archaeo-geophysical surveying on National Road Schemes 2001-2010'.. The research is funded by the NRA and supports a studentship that will be undertaken by Earthsound Director James Bonsall, who has taken a sabbatical from the company to study for a PhD.. Earthsound are providing James with geophysical equipment, survey assistants, transportation and a full suite of office and administration support.. There is considerable international interest in validating the outcomes of ground based remote sensing and the reappraisal of NRA schemes can play a major part via this research..
