SUMMARY:Terrane tectonics in southern Britain (online lecture)
DESCRIPTION:Dr Dave Schofield\, British Geological Survey\, Edinburgh \nDuring the 1970s\, the recognition of allochthonous terranes as discrete lithospheric fragments gave geologists a new tool kit to help describe the mosaic-like complexity of orogenic belts. Understanding that terranes could be dispersed and recombined accompanied realisation that strike-slip translation contributed significantly to orogenic development. \nIn applying this to understanding the\, largely concealed\, late Neoproterozoic and Lower Palaeozoic record of southern Britain\, conflicts in nomenclature\, scales of observation and focus of the geologist’s themselves has led to a confusing picture where terranes are essentially reduced to snapshots in time rather than lithospheric entities evolving in both time and space. \nThis talk takes a look at this problem and uses summaries of isotopic data to contrast Neoproterozoic rocks with their Cambrian cover successions in southern Britain and those in the Caledonian-Appalachian Orogen as a whole\, and looks at when the component terranes may have been assembled and largely stabilised. \nEarlier interpretations of the orogeny compare southern Britain with Avalon Peninsula in Newfoundland based on the similarity of their Cambrian shelfal sedimentary successions and cold water faunas\, known as East and West Avalonia respectfully. However\, isotopic studies of the Precambrian basement to southern Britain show that it more closely resembles that of other terranes that formed around the continental margin of West Gondwana\, Meguma of Nova Scotia and Ganderia of Central Newfoundland and New Brunswick of the northern Appalachians. \nSimilarly\, U-Pb zircon provenance studies of the overlying Cambrian cover successions show that North Wales and the Midland Platform of England most closely resemble Meguma while those of Anglesey (Monian Composite Terrane) and the Leinster-Lakesman Terrane most closely resemble Ganderia. While in the northern Appalachians these terranes largely travelled separately before their accretion in a piecemeal fashion onto the continental margin of Laurentia; in the UK they were juxtaposed during the Early Ordovician Monian Orogeny\, after which southern Britain and Ireland probably travelled as a single terrane before arriving on Laurentia during the Silurian. \nDavid undertook a PhD at Keele University in 1995 and has worked with the BGS in various roles since then. Currently he is Director\, Energy Systems and Basin Analysis\, having previously been Chief Geologist\, Wales. \nThis lecture will be held as a Zoom meeting. Society members for whom we have email addresses will be sent an invitation a few days before the event. If you are a member but are not on our email list\, or a non-member who would like to join the meeting\, please email the society’s meetings secretary to request an invitation.

SUMMARY:Large-scale CO2 removal via enhanced rock weathering (online lecture)
DESCRIPTION:Professor David Beerling\, University of Sheffield \nEnhanced silicate rock weathering (ERW)\, deployable with croplands\, has potential use for atmospheric carbon dioxide (CO2) removal (CDR)\, which is now necessary to mitigate anthropogenic climate change. ERW also has possible co-benefits for improved food and soil security\, and reduced ocean acidification. The talk will discuss the challenges and opportunities of ERW deployment\, including the potential for excess industrial silicate materials (basalt mine overburden\, concrete\, and iron and steel slag) to obviate the need for new mining\, as well as uncertainties in soil weathering rates and land–ocean transfer of weathered products. \nFurther Reading \nBeerling\, D.J. 2020. Potential for large-scale CO2 removal via enhanced rock weathering with croplands. Nature\, 583\, 242–248. \nDavid is the Director of the Leverhulme Centre for Climate Change Mitigation and Sorby Professor of Natural Sciences in the Department of Animal and Plant Sciences (APS) at the University of Sheffield.\nHe has written two popular science books: “The Emerald Planet” and “Making Eden”. \nThis lecture will be held as a Zoom meeting.

SUMMARY:The geology of the Mendip Hills (online lecture)
DESCRIPTION:Dr Doug Robinson\, University of Bristol (retired) \nSomerset is a unique county with more geological periods present than most other English counties. The city of Wells is well known as England’s smallest city but within its immediate backdrop the rocks record a longer geological history than any other English city – a 200 million year (Devonian to Jurassic)\, 6\,000 km journey from the southern tropics across the equator into northern latitudes. \nThis lecture will be held as a Zoom meeting.

SUMMARY:Bird evolution from the Late Cretaceous onwards (online lecture)
DESCRIPTION:Dr Daniel Field\, University of Cambridge \nDaniel will talk about evolution of birds across mass extinctions\, and the timescale of the modern bird radiation. The end-Cretaceous (K–Pg) mass extinction dramatically affected vertebrate life worldwide. He and his colleagues are trying to decipher how this event affected birds and other vertebrates through fieldwork and lab-based studies. When in Earth history did the first evolutionary divergences among modern birds take place? How old are the major avian clades? \nFurther Reading \nField\, D.J.\, Benito\, J.\, Chen\, A.\, Jagt\, J.M.W.\, Ksepka\, D.T. 2020. Late Cretaceous neornithine from Europe illuminates the origins of crown birds. Nature\, 579 397-401.\nField\, D.J.\, Berv\, J.S.\, Hsiang\, A.Y.\, Lanfear\, R.\, Landis\, M.J.\, Dornburg\, A. 2020. Timing the extant avian radiation: The rise of modern birds\, and the importance of modeling molecular rate variation. PeerJ Preprint of in-review manuscript: https://peerj.com/preprints/27521/ \nDaniel is an evolutionary palaeobiologist at the University of Cambridge (Department of Earth Sciences). He hails from Alberta\, Canada and is a graduate from the University of British Columbia. He did his PhD at Yale and worked at the Smithsonian and Denver before coming to Cambridge in 2018. He uses the vertebrate fossil record to help answer questions about how\, where\, and when Earth’s modern biodiversity arose. He is passionate about natural history\, evolution\, and science outreach\, and enjoys studying and photographing Earth’s vertebrate biodiversity in the field. \nThis lecture will be held as a Zoom meeting.

SUMMARY:The Argyll Group: two beauts (online lecture)
DESCRIPTION:Professor Bruce Levell\, University of Oxford \nThe Neoproterozoic Argyll Group (Dalradian Supergroup)\, is a well-exposed\, 10 km thick\, sequence recording a transition from glacial through shallow marine to slope and deep-water sediments and pillow lavas. It probably represents the rift-to-drift sequence of the Laurentide margin of Iapetus. \nTwo units are presented: the Port Askaig Formation\, probably the Sturtian phase of “Snowball Earth”\, and the Jura “Quartzite”\, a 5 km thick cross-bedded\, sandstone. These allow general points to be made about “Snowball Earth” and preservation bias in the sedimentary record respectively. \nBruce has a DPhil from the University of Oxford. He worked for Royal Dutch Shell from 1978 to 2013\, when he became a visiting professor back at the University of Oxford. With Shell he worked as an explorer in Sarawak\, Sabah\, USA\, UK and Oman\, and as a researcher on basin modelling\, seismic stratigraphy\, and regional geology. He was variously Exploration Manager in Petroleum development Oman\, VP of New Ventures in Shell Global Exploration\, VP Emerging Technologies in Shell Research and Shell Group Chief Scientist for Geology. Within Shell he led several advanced training programmes in geology and in leadership. He was awarded the Silver Medal of the Petroleum Group\, Geological Society of London\, in 2009. He is currently editing a sedimentology textbook as well as being engaged in research projects in Scotland\, Oman\, and Zambia. \nThis lecture will be held as a Zoom meeting. Society members for whom we have email addresses will be sent an invitation a few days before the event.

SUMMARY:New isotopic age determinations from the Northern Highlands and their implications (online lecture)
DESCRIPTION:Professor Matthew Thirlwall\, Royal Holloway\, University of London \nOver the last 15 years we have carried out a large number of new age determinations on metamorphic rocks from the Moine and its basement inliers. Some of these are published and some not. They include Lu-Hf and Sm-Nd ages on garnets and Rb-Sr ages on white mica and biotite. Lu-Hf garnet ages are probably close to crystallization ages\, while Sm-Nd garnet ages in most cases represent stages on a cooling trajectory. This can clearly be demonstrated on a few samples where core Sm-Nd ages are younger than rim Lu-Hf ages. White mica ages are in some cases substantially younger than Sm-Nd garnet\, and in other cases agree well. \nWe see a long record of Proterozoic events\, but there are few if any Archean ages on the basement inliers. There are almost no Silurian ages\, neither from garnets\, nor from white micas\, implying that Scandian events did not result in substantial new garnet or mica growth. White mica ages largely cluster in the late Ordovician around 445Ma\, and are clearly too old to reflect final collision. \nBackground reading: Bird\, Anna; Cutts\, Kathryn; Strachan\, Rob; Thirlwall\, Matthew F.; Hand\, Martin.

Precambrian Research\, 305\, p. 283-294. \nMatthew was an undergraduate in Oxford and did his PhD in Edinburgh\, on the Late Caledonian volcanic rocks. Since 1984 he’s been employed by Royal Holloway University of London\, and the last few years has enjoyed only 20% employment. \nThis lecture will be held as a Zoom meeting.

SUMMARY:Virtual field trip to the Braid & Blackford Hills
DESCRIPTION:Dr Angus Miller of Edinburgh University will present this virtual excursion. \nThe Braid and Blackford Hills\, which dominate the landscape of south Edinburgh\, are two large tapered masses of volcanic rock. In this virtual geology walk\, we’ll travel across the hills to discover two main lava flows of different composition with a thin layer of ash in between. We will explore the volcanic history of the area\, the story of erosion and glaciation\, and the views from the summits. The deep valley of the Hermitage of Braid between the hills also has an interesting origin\, with ice and meltwater picking out the contrasts between different rock types. \nThis event is part of the Scottish Geology Festival and will be held as a Zoom meeting.

SUMMARY:The geology of Mercury (online lecture)
DESCRIPTION:Professor Simon Cuthbert\, AGH University of Science and Technology\, Krakow \nMercury has been recognised as a “wanderer” of the night sky since Babylonian times\, but its proximity to the Sun has made it a difficult body to study. The situation has changed dramatically since the recent MESSENGER mission\, which has revealed a fascinating and distinctive member of the family of terrestrial planets. \nDubbed the “iron planet” it has a huge metallic core and a relatively thin rocky mantle. In some ways the geology and landforms of Mercury resemble Earth’s Moon with its heavily cratered surface\, extensive smooth lava plains and lack of an atmosphere\, but it is unusually dark – a possible vestige of a primordial crust made of graphite! Tectonic features suggest that the entire planet has shrunk by several kilometres since it originally solidified. \nThis presentation will explore current knowledge about this rather uncelebrated planet and consider how its curious nature might be inherited from the special environmental conditions close to the Sun during the very earliest history of the Solar System. A look ahead to the upcoming Bepi-Colombo mission will anticipate some exciting new insights about this mysterious “pink dot”. \nSimon is long-standing member of the society and was until recently based at the University of the West of Scotland. He is now Assistant Professor in the Department of Mineralogy\, Petrography and Geochemistry\, at the University of Science and Technology\, in Krakow\, Poland. \nThis lecture will be held as a Zoom meeting. Society members for whom we have email addresses will be sent an invitation a few days before the event. If you are a member but are not on our email list\, or a non-member who would like to join the meeting\, please email the society’s meetings secretary to request an invitation. \n  \n

SUMMARY:Beach pebbles: windows into Scotland's geological past (online lecture)
DESCRIPTION:Dr Angus Miller\, University of Edinburgh \nScotland’s geology is incredibly varied; this small country has a fantastic variety of rock types formed over a vast reach of geological time. The best place to see this variety is on Scotland’s pebble beaches. How do pebbles form and why do some survive better than others? What processes result in some beaches having a wide range of pebble types and sizes\, and others being dominated by a single rock type. What can a pebble tell you about Scotland’s geological history? \nThis is an online event organised by the University of Edinburgh’s Short Courses department. More information and registration instructions can be found on the university’s website.

SUMMARY:Virtual field trip to the southern Rhinns of Islay
DESCRIPTION:David Webster has been asked to make this presentation by the Open University Geological Society and they are happy for others to join in. This excursion will be a little more technical than David’s previous Islay field trips. It will look at the Rhinns Complex deformation history and its enigmatic contact with the overlying Colonsay Group. Do the newly-discovered conglomerate exposures show us the very base of the Dalradian? If so\, how old is it? How many deformations were there? Is the Kilchiaran Shear zone really folded? \nThe event will take place during the normal Gelogical Society of Glasgow lecture slot – i.e. the second Thursday of the month at 7:30 pm – and will be held as a Zoom meeting. Society members for whom we have email addresses have been sent instructions on how to join the meeting. If you are a member but did not receive an email\, or a non-member who would like to join the meeting\, please email the society’s meetings secretary to request the instructions. \n

SUMMARY:Virtual field trip to Islay: the Snowball Earth story
DESCRIPTION:This trip\, the second of David Webster’s series of virtual field trips to Islay\, Jura and Colonsay\, will focus on the “Snowball Earth” story on Islay. It will be an excursion from Ballygrant to Port Askaig via Beannan Buidhe and the Sound of Islay. Normally this entails two quite long separate walks because one part of the coast is generally impassable\, but we have the advantage of being able to “zoom” round the headland. The excursion is going to be included in David’s forthcoming Volume II of “A Guide to the Geology of Islay”; so you will be getting a sneak preview. \nWe hope that the “expert panel” of Tony Spencer\, Ian Fairchild and Alasdair Skelton will be on hand again to help answer questions. \nThe event will be held as a Zoom meeting. Society members for whom we have email addresses have been sent instructions on how to join the meeting. If you are a member but did not receive an email\, or a non-member who would like to join the meeting\, please email the society’s meetings secretary to request the instructions. \n  \n

SUMMARY:Virtual field trip to North Islay
DESCRIPTION:This is the first of a series of virtual field trips to Islay\, Jura and Colonsay being presented by David Webster. It will be an excursion to the north-east coast of Islay\, the best place to see the stromatolites of the Bonahaven Fm in all their 3D glory. The trip will also feature a lot of other really interesting geology\, some classic Ice Age geomorphology and great coastal scenery. \nThis is Excursion 9 in A Guide to the Geology of Islay by D. Webster\, R. Anderton & A. Skelton (Ringwood Publishing\, 2015). It’s a long walk in real life\, and an armchair version could suit a lot of folk! \nThe event will be held as a Zoom meeting.

SUMMARY:Members' Night
DESCRIPTION:Because of the Covid-19 pandemic\, this event will be held by means of a Zoom webinar. The programme is as follows. \n7.15: Meeting open – connect to Zoom (instructions sent by email)\n7.30: Introduction by Walter Semple\n7.35: “Sea kayak trip to the west coast of Jura” by David Webster\n7.55: Break (to allow people to clap and refresh beverages)\n8.10: Questions to David Webster\n8.20: “Contrasting islands: The geology of Eigg and Rum” by Angus Miller\n8.45: Questions to Angus Miller\n8.55: “The Carbon game: adventures of a globe-trotting carbon atom” by Simon Cuthbert\n9.10: Questions to Simon Cuthbert\n9.20: Vote of thanks by the president\, Neil Clark \nSociety members for whom we have email addresses have been sent instructions on how to join the meeting. If you are a member but did not receive an email\, or a non-member who would like to join the meeting\, please email the society’s meetings secretary to request the instructions. \nThe audience will be muted during the talks by the host to reduce background noise. You can unmute yourself if/when you want to ask a question. There is the facility to “chat”: you can type a question at any time and the chair/host can see these and call on you to ask your question or for the speaker to respond. The questions will be taken at the end of each talk. \nDavid Webster’s talk on Jura is a trial of a virtual field trip; so questions during the presentation are fine as that’s what would happen naturally. Real field trips are usually accompanied by a hand-out\, and to help you suspend reality David has created a map for you to print and use as he takes you to the various localities. You can download the map here.

SUMMARY:Ardnamurchan
DESCRIPTION:This excursion has been cancelled because of the coronavirus outbreak. We hope to reschedule it for 2021. \nLeader: Con Gillen \nField days: Friday (afternoon)/ Saturday/ Sunday/ Monday (morning) \nThe Ardnamurchan peninsula\, which includes the most westerly point of the Scottish mainland\, is composed mainly of the remains of an early Palaeogene volcano with three centres of activity. Part of the North Atlantic Igneous Province which includes Mull\, Rum and Skye\, it was erupted into Moine metasedimentary rocks and overlain by a sequence of thin sedimentary rocks. Ardnamurchan displays classic geology on a colossal scale\, with features such as mixed magma\, ash flows\, ring dykes\, cone sheets and examples of “airfall” rocks formed from lava ejected from the heart of the volcano – it is regarded as almost a “textbook volcano”. A drive across the peninsula is a journey through its magma chamber. Its overall structure is difficult to perceive on the ground but from space the picture is much clearer – rings of once molten magma can be seen to define a series of almost perfect circles. These are the lower parts of the volcano after the superstructure has been planed off by erosion\, in this case\, effectively\, by the last Ice Age. We plan to visit significant localities of igneous\, sedimentary and metamorphic rocks and there may also be the opportunity to sail to Tobermory (whales!) for those who wish to do less climbing! \nAccommodation will be B & B in Kilchoan etc.; transport will be in shared cars. \nIf you are interested\, please contact the Residential Excursions Secretary\, Maggie Donnelly\, at restrips@gsocg.org as soon as possible\, because accommodation is not plentiful and gets booked up quickly.

SUMMARY:Islay
DESCRIPTION:This excursion has been cancelled because of the coronavirus outbreak. We hope to reschedule it for 2021. \nLeader: David Webster \nField days: Friday (afternoon)/ Saturday/ Sunday/ Monday (morning) \nThis is a repeat of the 2019 Islay trip. Priority will be given to members who could not come last year because the trip was already full. \nThe geology of Islay is amazingly varied – 1800 Ma gneiss\, Precambrian metasediments and fossil stromatolites\, the famous Port Askaig Tillite (possible “Snowball Earth”?)\, low grade metamorphic Dalradian rocks retaining original sedimentary structures\, reactivated and reversed extensional faults\, substantial mineralisation\, 60 Ma igneous intrusions (opening of the Atlantic Ocean) and a large selection of Quaternary Ice Age features. We plan to visit key localities with the aid of “A Guide to the Geology of Islay” by David Webster\, Roger Anderton & Alasdair Skelton. \nBoulder of granite in Port Askaig tillite\n  \nAccommodation will be B & B in Bowmore; transport will be in shared cars. \nIf you are interested\, please contact the Residential Excursions Secretary\, Maggie Donnelly\, at restrips@gsocg.org as soon as possible\, because accommodation is not plentiful and gets booked up quickly.

SUMMARY:Breaching of the Dover Strait and the creation of “Island Britain” (lecture)
DESCRIPTION:This lecture has been cancelled because of the coronavirus outbreak. We hope to reschedule it for autumn 2020. \nProfessor Jenny Collier\, Imperial College\, London \nFor much of our pre-history\, a permanent land bridge existed between Britain and France at the Dover Strait. How and when it was removed\, however\, was previously unknown. We analysed a new regional bathymetric map of part of the English Channel derived from a compilation of both single- and multi-beam sonar data\, which shows the morphology of the seabed in unprecedented detail. \nWe observed a large bedrock-floored valley that contains a distinct assemblage of landforms\, including streamlined islands and longitudinal erosional grooves\, which are indicative of large-scale subaerial erosion by high-magnitude water discharges. Our observations support the megaflood model\, in which breaching of a rock dam at the Dover Strait (see artist’s impression on front cover) instigated catastrophic drainage of a large pro-glacial lake in the southern North Sea basin. This flow was one of the largest recorded megafloods in history and could have occurred 450\,000 to 200\,000 years ago. \nWe suggest that megaflooding provides an explanation for the permanent isolation of Britain from mainland Europe during interglacial high-sea-level stands. The breaching likely affected patterns of early human occupation in Britain by creating a barrier to migration which possibly explains the complete absence of humans in Britain 100\,000 years ago. The breach of the ridge\, and subsequent flooding\, also may have initiated the large-scale reorganisation of the river drainages in north-west Europe by re-routing the combined Rhine-Thames River through the English Channel to form the Channel River. \nBackground reading \nGupta\, S.\, Collier\, J.S. et al. 2007.

SUMMARY:Burning planet: the story of fire through time (lecture)
DESCRIPTION:Professor Andrew Scott\, Royal Holloway\, University of London \nThis talk will cover the past\, present and future of wildfires and their environmental effects and especially the role of fire in Earth systems processes. In particular I will concentrate on modern and ancient fires\, their products (charcoal) and effects\, including the rise of fire in the Devonian\, the evolution of late Palaeozoic fire systems and evidence for fire at the Paleocene-Eocene Thermal Maximum (PETM). \nCharcoal preserves the anatomy of the plants that have been burnt. Scanning electron microscopy is routinely used to study their morphology and anatomy and new methods of obtaining temperature of charcoal formation using reflected light microscopy have been developed. This has implications for both studies of natural wildfires as well as for our understanding of the human use of wood and charcoal as a fuel. \nBiogeochemical modelling suggests significant variation of atmospheric oxygen in deep time. Using a charcoal proxy for atmospheric oxygen over the past 350 million years there is evidence for significantly high levels of oxygen in the late Palaeozoic and in the Cretaceous suggesting high levels of fire at that time. This resulted in the rapid spread of weedy flowering plants in the Cretaceous.\nStudies of palaeocharcoal can also delineate changes in fire over the past 20\,000 years.

SUMMARY:Understanding the spatial variability of sedimentary deposits (lecture)
DESCRIPTION:Dr Amanda Owen\, University of Glasgow \nSedimentary systems are under the influence of a variety of processes that can vary considerably in time (seconds to millennia) and space (from the grain to basin scale). This talk will examine the spatial variability in fluvial response to the Paleocene-Eocene Thermal Maximum (PETM). The PETM occurred ~56 Ma and was a geologically abrupt global warming event in which temperatures increased from 5-8°C over ~200\,000 years due to a global release in carbon\, making it a close analogue to today’s global warming trends. The PETM has been interrogated at a number of terrestrial and marine localities across the globe; however\, the majority of these studies are not placed within a well-defined spatial and temporal context\, with study often limited to single successions and the deposits that lie immediately above and below the event. It is imperative that background “normal” conditions are understood in order for an assessment of response magnitude and extent to be made. Within this talk sedimentological observations from multiple PETM localities within the Bighorn Basin\, Wyoming\, will be presented within a newly defined quantified basin context. \nBackground reading: Owen\, A.\, Hartley\, A.J.\, Ebinghaus\, A.\, Weissmann\, G.S. & Santos\, M.G.M. (2019). Basin?scale predictive models of alluvial architecture: Constraints from the Palaeocene–Eocene\, Bighorn Basin\, Wyoming\, USA. Sedimentology\, 66(2)\, 736-763. (doi:10.1111/sed.12515) \nAmanda’s research focuses on understanding ancient fluvial deposits\, more specifically trying to understand the heterogeneity and predictability of fluvial deposits over a variety of scales from the basin to pore scale. Her research is primarily field based\, where she studies analogues (both ancient and modern) for application into the petroleum\, minerals (uranium and cooper) and groundwater industries. Alongside applied research she also looks to understand the effect that external controls (such as climate and tectonics) have on fluvial systems as well as try and better understand vegetation response to changes in fluvial environments. Her work is conducted through collaborative links at the University of Aberdeen\, University of New Mexico\, University of St Andrews and Universidade Federal do ABC and through the industry-funded consortium Fluvial Systems Research Group.

SUMMARY:Engineering geology of the Queensferry Crossing (lecture)
DESCRIPTION:John Brown\, Arup\, Edinburgh \nThe lecture will focus on the geology of the area of the crossing along with a detailed description of the engineering works required to form the foundations of the new bridge. Far more than one geologist or one organisation was involved in the crossing’s construction and the lecture will highlight the main parties involved and their roles and responsibilities. \nThe crossing is built on varied geology with almost every foundation bearing on a different rock type. However\, the central island of Beamer Rock and the high ground on either side of this narrowing in the Firth of Forth are formed from igneous intrusions. These igneous intrusions resisted the glacial erosion slightly better than the sedimentary rocks into which they were intruded with Beamer Rock providing an excellent foundation to support the 210 metre high central tower. The foundations for the north and south towers (as well as one of the southern piers) are founded on 25 to 30 m diameter circular steel caissons sunk to the top of the bedrock some 40-50 m below water level. Once positioned\, they were sunk into the seabed by a combination of precision dredging and ballasting with concrete to guide the caisson to its desired level and position. Once the base was cleaned and inspected underwater a thick concrete plug was poured within the cylinders to offset the effect of buoyancy and allow the construction of the reinforced concrete base for the foundations towers to be undertaken in the dry. The caisson approach is not that dissimilar to how 19th century engineers approached the foundations that support the original Forth Bridge. \nThe remaining foundations were constructed within sheet pile cofferdams with a combination of underwater and in-the-dry construction techniques. Some of the rock types could be excavated by mechanical means while others such as the dolerite at the central island of Beamer Rock required pre-treatment with underwater blasting before excavations could commence. \nThe geological information gathered prior to construction was translated into 3D numerical models in order to design the foundations. Each foundation excavation was rigorously inspected either directly by engineering geologists in the dry or when underwater with the assistance of divers and for foundations in deeper waters a remote camera dome was developed to carry out inspections up to 50 m below sea level in order to check that the design assumptions had been met or exceeded. The engineering expertise of the designer and contractor enabled the delivery of a complex set of foundations in a safe and efficient manner. \nJohn is an Associate with Arup and was responsible for overseeing the marine ground investigations and the marine cofferdam foundation construction works among other duties on behalf of the employer’s delivery team (EDT)\, having worked on the project for over a decade until its opening in 2017. \n
