Mae caer arfordirol Dinas Dinlle

Disgrifiad

Caer arfordirol gynhanesyddol bwysig y mae erydiad ar yr arfordir a’r tir yn cael effaith sylweddol arni yw Dinas Dinlle. Ni wyddom pryd yr adeiladwyd y gaer, ond credir iddi gael ei chodi yn ystod yr Oes Haearn ac iddi gael ei defnyddio o bosibl i amddiffyn y trigolion rhag llwythau rhyfelgar cyfagos ac, efallai, y goresgynwyr Rhufeinig.

Credir bod tua chwarter y safle wedi’i golli i erydiad a bod olion archaeolegol gwerthfawr wedi mynd i ddifancoll o ganlyniad, gan gynnwys yr amddiffynfeydd gorllewinol a rhan o’r tu mewn. Fel rhan o’r Prosiect CHERISH, byddwn yn ymchwilio i Ddinas Dinlle ac yn ei monitro’n ofalus er mwyn dysgu mwy am hanes y safle cyn i fwy ohono gael ei golli.

Menai Straits Marine Survey, Anglesey, Wales (2018)

Cylchlythyr

Cynnwys

This document is intended to provide a thorough overview of survey specifications, standards and quality control measures implemented during survey operations. It provides a record of the datasets acquired during operations and a description of how this data was modified (processed) and managed before leaving the vessel for final validation and distribution to the end user.

The CHERISH project identified a number of sites around Anglesey for which the project required detailed bathymetric surveys. Two main type of sites were targeted; islands and shipwrecks. Islands that were identified for survey were Dulas and Puffin in the north east of Anglesey and Skerries on the north west. The objectives of targeting these islands were to both further understand their evolution and to join bathymetric data with existing LIDAR data for analyses. A number of shipwrecks were also targeted. These shipwrecks were located in proximity to the islands and also at the south west entrance of the Menai Strait.
