A man with a grey beard and hair wearing a red t-shirt, khaki shorts, red socks and boots is pushing a magnetometer towards the camera. The mag consists of a frame with none vertical tubes, five of which have a sensor inside. There are two wheels at either end, and a vertical pole in the centre on top of which is a high accuracy dGPS. The grass is the field is yellow due to the drought. The ground slopes from right to left so that the mag is at an angle. In the background are some trees.
Fifty years (19/50). Ideally one should keep the sensors vertical... sometimes it is simply not possible! Here I am pushing the magnetometer at Verulamium in 2022. @uclarchaeology.bsky.social #RomanArchaeology #geophysics #magnetometry #Verulamium #VoteKris @hertshistory.bsky.social
