Overview of Terra Nova
Survey Projects
This is a list of survey projects which were either undertaken by Terra Nova Limited or carried out or directed previously by its Director, David Jordan. It is thus a record of the experience and expertise within the company.
Our practice is a team effort. Terra Nova Limited is very grateful for the hard work carried out for it by current and former employees, students and collaborators, to whom we owe much of the studies outlined below.
Please let us know if you want to find out more about any of these projects.

Thun-St.Amand, Valenciennes
Magnetic, electromagnetic and electrical resistance survey which revealed the structure of buried buildings and demolition debris across a heavily polluted 19th century metal smelter site.
West Deeping, Peterborough
Magnetic and electrical resistance survey which revealed the structure of a buried prehistoric ditched enclosure. Airphotograph replot and landscape analysis across a large area of drained fenland.
Stanground, Peterborough
Thermal and visible scanned airborne remote‑sensing study which identified areas of methane emission from a land‑fill.
Little Marlow, Bucks
Air‑photography study of possible archaeological sites.
Bucklesham, Suffolk
Air‑photography study of possible archaeological sites.
Eynsham, Suffolk
Air‑photography study of possible archaeological sites.

Magnetic survey which successfully detected a 10cm diameter borehole in a target area of 2000m2.
Pen‑y‑Crug, Powys
Magnetic and electrical resistance survey of a late‑Medieval tile and brick producing site.
Pen‑y‑Gaer, Powys
Magnetic and electrical resistance survey of a possible Roman bath‑house site.
Y‑Gaer, Powys
Magnetic and electrical resistance survey of a Roman fort.
Llangynydr, Powys
Electrical survey of a deserted Medieval village.
Dolaucothi, Dyfed
Magnetic and electrical resistance survey of a Roman road, field system and associated dwellings.
Bury Holms, Gower
Magnetic and electrical resistance survey associated with a geo‑archaeological survey of an important Mesolithic site.
Castilleja, Seville
Three‑dimensional electrical resistance survey to identify the internal structure of an important Bronze Age tumulus.
Pallomares, Seville
Magnetic and electrical resistance survey of a small Arab site.
Estepa, Seville
Magnetic and electrical resistance survey of a Roman and Medieval citadel.
La Bussiere, Loire
Magnetic, magnetic susceptibility and electromagnetic survey of a late‑Medieval metal working site in dense woodland.
Seville Cathedral, Seville
Magnetic and electromagnetic survey which located tombs and other structures buried beneath the cathedral floor.
Ewenny Quarry, Glamorgan
Magnetic and magnetic susceptibility survey which identified areas of possible archaeological activity around an enclosure, but failed to provide further detail even where already known.
Treffeca House, Powys
Magnetic and electrical resistance survey of a lost late Medieval garden.
Tusculum, Frascati
Unsuccessful magnetic and electrical resistance survey of a complex, disturbed Roman hilltop site.
Fuengirola, Andalucia
Magnetic and electrical resistance survey which revealed the details of a former Roman fish‑processing factory.
Oripo, Seville
Magnetic and electrical resistance survey which revealed the buried structures across part of a small Roman town.
Newton St Loe, Bath
Magnetic survey to define the structure of a prehistoric site.
Pumpsaint Roman Fort, Dyfed
Magnetic and electrical resistance survey which resolves controversy concerning the details of a Roman Fort and vicus.
Coed Canlas, Pembroke
Magnetic and electrical resistance survey which revealed many details of a buried formal Tudor garden.
Guissona, Catalunya
Electrical resistance survey which identified the structure and a probable gate through the wall of a Roman town.
Llanllyr, Dyfed
Magnetic and electrical resistance survey which revealed archaeological remains and occupation debris.
El Rasillo, Barajas
Magnetic and electrical resistance survey which revealed the remains of Roman occupation. A broader geoarchaeological study discussed the processes by which the site had formed.
Cheles, Extramadura
A combined magnetic and electrical resistance survey which found the, previously unknown, remains of a Roman villa and mapped a known Chalcolithic site.
Avlon Works, Avonmouth
A detailed electromagnetic survey which mapped the changing depth and lithology of estuarine alluvial deposits and peats, confirmed by excavation – as well as an unexpected gas pipeline.
West Wick
An extensive electromagnetic, electrical resistance tomography, ground-radar and coring survey which revealed the structure of series of estuarine alluvia and showed the probable form of a, now-buried, creek system.
Merebank Rhine, Avonmouth
An extensive electromagnetic, electrical resistance tomography and coring survey which, as at West Wick, revealed the structure of series of estuarine alluvia and showed the probable form of a, now-buried, creek system. Subsequent excavation showed the relationship of the deposits revealed in these surveys to a sequence of buried incipient soils in which archaeological remains are embedded.
Mairena, Seville
A detailed electromagnetic survey which, by mapping only the weak EM response of the underlying marl rock, showed that archaeological remains are probably absent from this site.
Margam Park
geophysical survey 
A detailed caesium magnetometer and electrical resistance survey which mapped the structure of former gardens and roadways, thus showing that significant remains are buried within an area where development was proposed to take place.
Genfford Farm, Talgarth, Powys
A small magnetometer survey which showed that only modern debris was detectable within the area and that there were no detectable remains of former ceramic manufacturing.
