Archaeological Prospection, EarlyView.ABSTRACT Airborne laser scanning (ALS, lidar) has become a key method for studying ancient Maya landscapes, offering unprecedented visibility of anthropogenic terrain modifications in densely forested environments. Despite this progress, the visualization of elevation data remains understandardized, with many researchers relying on ad hoc or ...

Pre‐Excavation Identification and Dating of Iron Age Destruction Events
Archaeological Prospection, EarlyView.ABSTRACT To maximize extracted data while minimizing excavated areas, archaeologists increasingly use archaeological surveys, geophysical surveys and remote sensing to gain comprehensive regional pictures and decide if and where to excavate. The goal of this effort is to leave sufficient unexcavated areas for future generations and save time and ...

Archaeological Prospection, EarlyView.ABSTRACT We present a study that combines several marine geophysical techniques to detect and map archaeological sites from the Roman period in the shallow waters of the Venice Lagoon, Italy. We employed marine electrical resistivity tomography (M‐ERT), a drone‐based unmanned surface vehicle (USV) multibeam sonar, and subbottom profiler technology to ...

Crustal structure beneath the Trondelag Platform and adjacent areas of the Mid-Norwegian margin, as derived from wide-angle seismic and potential field data [PDF]
, 2010 The outer mid-Norwegian margin is characterized by strong breakup magmatism and has been extensively surveyed. The crustal structure of the inner continental shelf, however, is less studied, and its relation to the onshore geology, Caledonian structuring,

Geophysical Investigations at the Artemision at Amarynthos of Euboea (Greece)
Archaeological Prospection, EarlyView.ABSTRACT A combination of resistivity mapping and three‐dimensional electrical resistivity tomography (ERT) was used to investigate the subsurface of the sanctuary of Artemis Amarysia in Amarynthos, Euboea (Greece), an area where archaeological remains from the Bronze Age to the post‐Byzantine period are preserved.
