 Helo, arweinydd i am ymlaen, John Lewis, a rwy'n gweithio ar y Gymdeith月 Llywodraeth Llywodraeth, gallwn i'n nhw'n nodi'r ddigwydd o'r llyfr ymlaen. A ydych chi'n bwysig ar y Llwyddon, yn fawr i'r gwybod a'n ddod i'n ymlaen i'r gweithio ar y Llwyddon, for our online conference Lost Frontiers And Drowned Landscapes In Britain And Beyond. The Society of Ant attentrs is an educational charity that promotes the understanding of the human past and recognises distinction in this field through elections to it's fellowship. Founded in 1707 the Society meets its remit for the purpose of the advancement and furtherance of the study and knowledge of the antiquities and history of this and other countries I gael ymdod o gweithio arweithio ymdod ym Mhwylwyr Hyfyrnt yn Llywodraeth, ac, yn Celfysgawr, gyda'r cyllid ymgylchedd Gwylwyr William Morris yn y Cotswol. Mae gennym y Cymru yn ddwy'r gwybod o gafodd, ddwy'r cofnogol, a'r lleol yn deisemuniaid. Mae gennym ymdod o'r gafodd o'r gafodd. Mae gennym yn ddiddordeb i'r gweithio'r gafodd ymgylchedd. yr unig i'r ffordd o'i llwyth i'r materiol yn ymwneud, ac rwy'n gŷnodd â ymwneud yn y cyfnodd ar y cyfnodd.

Dyma ym Mhwng 2020, mynd i'r rwyr o'r program yma yn ymlaen, a'r oedd yn ymwyfnol ym mhwyfyr o'r with hundreds of people joining us for all our lectures and events from all over the world. Today's conference has been organised by fellows Professor Jeff Bailey FSA and Professor Vince Gaffney FSA. I'd like to thank them for the time and commitment to this conference which was postponed from last autumn due to COVID. The conference is in collaboration with the ERC Research Project, Europe's Lost Frontiers and will be part of presenting the results. dyna dyna'r bwysig o'r gweithio gyda'r hynny'n gwneud o'r progectau hynny. Mae'n ddod i'n ymdyn nhw'n rwy'n ddod i'n gweithio'r 500 yng Nghymru ar y qufnod lluniwr ar y ddechrau'u cynghwil yng Nghymru.

However, it is massively resource intensive and as yet has attracted very little RCUK research funding. All the major funding has been European and the project has also been dependent on the goodwill of European partners for access to research vessels. Big developments will be happening in North Sea and we as archaeologists must be ready to respond. Future research and researchers must be supported if this lead is not to be lost. I'll now pass on to Geoff, who is going to say a few words about how this event came about and the purpose of it. And he'll also provide some information on how people can ask questions. So, Geoff, over to you. Good morning. I've got three opening remarks as the chairman of this morning's session. First of all, to the speakers. You have a time limit, which I shall monitor. I shall turn my screen and microphone off while you're speaking. When you're close to the end of your talk, I will turn my video on again. If you don't take that hint and you hit the deadline, I'll turn my microphone on just to establish that protocol. Secondly, to the audience. There is an opportunity and will be an opportunity to ask questions in the normal fashion. But if you want to do so, please remember that you have to type your question into the chat box at the bottom of your screen. I will then read out the questions depending on the time available. We're bound to lose some time, but we'll see how we go. If worse comes to worse, the speakers might reply to you in the chat box. The third comment that I want to make is about how this meeting came about. It originated as two quite separate ideas over two years ago. I proposed to the Society of Antiquaries, their research committee, for which I'm a member, that we have a one day meeting on this theme. I was aware that in the UK and Britain, in particular Scotland, England, Wales, there are many people working on this theme. Too many actually to fit even within a one day meeting, which is the standard society format for a collective event. That proposal was accepted. At about the same time, Vince Gaffney, who's on the Council of the Society, was in discussion about hosting the final workshop of the Lost Frontiers project. So we very quickly combined forces to make this a two day event. Of course, this was all in pre COVID times designed for people who live or work within easy travelling distance of central London. That constraint has been removed, as we all know now, thanks to international video conferencing technology. Nevertheless, the original format remains as is essentially a British predominantly a British affair. But beyond in the title, which needs explanation. That recognizes the fact that there are many other people working on this theme, especially amongst our European neighbors. The Southern North Sea is shared by five countries in Western Europe. We have some of those people talking as part of the landscape project today. The other element is that in tomorrow's meeting, three of the speakers, myself, Jonathan Benjamin Helen far are actively engaged in field work in Australia, as well as in the UK. The theme are rather exotic outlier to combine with Britain. But we should remember that Australia is par excellence the maritime continent. It is a continent where human entry always required fairly lengthy sea journeys from mainland Southeast Asia. And we know that was happening at least 50,000 years ago, perhaps even earlier. The maritime strain is deeply embedded in the history of the Australian continent. It is still there. It is ingrained in the indigenous Australian Aboriginal world view with its emphasis on sea country. And the history of that continent has a lot to teach us, I think, about what might have been going on along coastlines and other parts of the world and in other continents. And has the potential to alter our perspective on world history. More of that tomorrow that today's talks of entirely focused on the Europe's Lost Frontiers project, which is led by Vince Gaffney who's going to give the opening talk. Vince has shouldered the burden of leadership by giving himself the shortest amount of time to talk. I won't dwell too much, but I should introduce Vince. He's quite well known to many of us, both nationally and internationally, famously so for an earlier project that he led on the North Sea paleo landscapes prize winning project. He's been frustrated in a remarkable way just how much information about features of the drowned landscape can be extracted with sufficient computational power from the seismic records of the offshore oil and gas industries. The new project builds on that and indeed that earlier project paved the way for the new project funded by the European Research Council. Which is using different and new technologies and techniques dedicated to answering archaeological questions rather than discovering oil and gas deposits beneath the seabed. So without further ado, I will invite Vince to give his talk on the Europe's Lost Frontiers project, the challenges of exploring the landscapes beneath the southern North Sea. Vince, over to you.
