On Thursday I visited Old Scatness and Jarlshof for the first time. Compared to Mousa, the scale of these archaeological sites are staggering: many roundhouses of different periods surround the central broch at both. As my supervisor Dr Val Turner showed me and colleagues around Old Scatness, James was busy getting laser scans around the site (once you start, you can’t stop scanning)!
Val interviewed me, Lyn and Andy for Radio Scotland about my PhD project and the vision for all three of these amazing Iron Age sites. Her recording was broadcast later that day and on Friday – first claim to fame! I’ll post here and on Twitter when I find out the exact time her more in-depth interview is broadcast.
After data swapping and backing up during lunch at the Sumburgh Hotel, we headed to Jarlshof. The HES team even had time to take a few initial laser scans around the site, following the permanent survey markers that Mike recently installed so the condition of the site can be monitored with accuracy in the future. The long history of Jarlshof is amazing (much more detailed info here: https://www.historicenvironment.scot/visit-a-place/places/jarlshof-prehistoric-and-norse-settlement/), but the fact that just half of the broch has survived to present highlights just how under threat many archaeological sites are from coastal erosion. The defences put in place at Jarlshof are strong, but it will be useful to monitor them over time and laser scanning can do this with great detail.
After our Historic Environment Scotland colleagues departed on Thursday, me and Andy returned to Old Scatness on Friday to acquire some more scans and take photography for SFM photogrammetry. I laser scanned areas of Old Scatness with the FARO Focus X330 that the long range Leica P40 may not have covered, and by the end of the day much of the site has been scanned and recorded. With permission from Sumburgh Air Traffic Control and DJI, Andy piloted the DJI Mavic SUA over Old Scatness to take aerial photos across the site, giving us excellent coverage which will help to feed into the terrestrial scan data and photos for photogrammetry.
Overall the amount of data acquired on this fieldtrip has exceeded all my expectations! It’s going to look amazing once it’s all been processed (my next major step in the PhD). Tomorrow I’ll be visiting Shetland’s Archives and Museum, run by my external partner Shetland Amenity Trust (https://www.shetlandmuseumandarchives.org.uk/) to investigate historic records of my three sites. I’m hoping to get a better sense of their history from past researchers and their notes and images.
