On the first day 31<sup>st<\/sup> May, the 2015 grid was extended to the small field across the track from the 2015 location. Strong gusts of wind made getting started quite difficult and later increasingly heavy rain stopped work by lunchtime. The day\u2019s activity was limited to proving with the gradiometer that the overhead power lines were not going to interfere significantly with the magnetometry signal. The second day 2<sup>nd<\/sup> June was much more productive with the survey of the small field being completed and the grid extended across the stream into the large field north-east of the cottages. The final day 3<sup>rd<\/sup> June saw the completion of the survey of the large field.<br \/>\n<a href=\"http:\/\/www.berksarch.co.uk\/index.php\/geophysics-survey-at-la-hyde\/la-hyde-2016-2\/\" rel=\"attachment wp-att-2561\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2561 aligncenter\" src=\"http:\/\/www.berksarch.co.uk\/wp-content\/uploads\/2016\/04\/La-Hyde-2016-2.jpg\" alt=\"La Hyde 2016-2\" width=\"573\" height=\"567\" srcset=\"https:\/\/www.berksarch.co.uk\/wp-content\/uploads\/2016\/04\/La-Hyde-2016-2.jpg 573w, https:\/\/www.berksarch.co.uk\/wp-content\/uploads\/2016\/04\/La-Hyde-2016-2-300x297.jpg 300w\" sizes=\"auto, (max-width: 573px) 100vw, 573px\" \/><\/a><br \/>\nThe data presented here are the nearly raw output of the gradiometer via the Snuffler software but without filtering or image enhancement; the display was set to \u2018clip\u2019 with thresholds at \u00b115. The\u00a0 striping results from walking the instrument up and down the survey lines. There are also some whitish areas at the edges of the plots which are almost certainly due to getting too close to wire fences. The overhead power lines have not intruded on the survey at all; nor has spoil from digging the \u2018Canal\u2019. There is an anomaly at the north-west corner near the cottages and a hint of another in the south-east corner. There are a few smaller anomalies which seem to have linear though quite widely spaced out relationships suggestive variously of an older track, a ditch\/stream, perhaps a line of fence posts. However, there is no evidence for remains of any buildings in the 2016 data.<\/p>\n<p>The final picture shows the overlay using the QGIS software of both 2015 and 2016 gradiometer data with the combined Ordnance Survey mapping from both current and original editions.<br \/>\n<a href=\"http:\/\/www.berksarch.co.uk\/index.php\/geophysics-survey-at-la-hyde\/la-hyde-2016-3\/\" rel=\"attachment wp-att-2563\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2563 aligncenter\" src=\"http:\/\/www.berksarch.co.uk\/wp-content\/uploads\/2016\/04\/La-Hyde-2016-3.jpg\" alt=\"La Hyde 2016-3\" width=\"547\" height=\"410\" srcset=\"https:\/\/www.berksarch.co.uk\/wp-content\/uploads\/2016\/04\/La-Hyde-2016-3.jpg 547w, https:\/\/www.berksarch.co.uk\/wp-content\/uploads\/2016\/04\/La-Hyde-2016-3-300x225.jpg 300w\" sizes=\"auto, (max-width: 547px) 100vw, 547px\" \/><\/a><br \/>\n<i>Contains Ordnance Survey data \u00a9 Crown copyright and database right (2015)<\/i><\/p>\n<h2>2017<\/h2>\n<p><strong>13th to 15th June<\/strong><\/p>\n<div class=\"\">The location is the suspected site of the Tudor village of La Hyde, believed to lie to the east of Sulham Lane between Pangbourne and Purley-on-Thames.<br \/>\n<a href=\"http:\/\/www.berksarch.co.uk\/index.php\/field-projects\/image001\/\" rel=\"attachment wp-att-3593\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-3593 aligncenter\" src=\"http:\/\/www.berksarch.co.uk\/wp-content\/uploads\/2016\/04\/image001.jpg\" alt=\"\" width=\"413\" height=\"266\" srcset=\"https:\/\/www.berksarch.co.uk\/wp-content\/uploads\/2016\/04\/image001.jpg 413w, https:\/\/www.berksarch.co.uk\/wp-content\/uploads\/2016\/04\/image001-300x193.jpg 300w\" sizes=\"auto, (max-width: 413px) 100vw, 413px\" \/><\/a><\/div>\n<div class=\"\">\n<p>This year we want to use resistivity to check the 5m strips up to the wire fences on either side of the track from the Home Farm yard to the cottages that we could not explore using magnetometry in 2015 (grey area with oil pipeline on the left) and 2016 (two grey areas on the right)<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>BAS2017_P05 2016 Last year the Society carried out a geophysics and topographical survey of the suspected site of La Hyde to the east of Sulham Lane between Pangbourne\u00a0and Purley on Thames and several members of the Society enjoyed a walk round the site and lunch in the pub at Tidmarsh.
