SUMMARY:Space weather and geomagnetically induced currents
DESCRIPTION:Space Weather encompasses a wide variety of physical phenomena that are ultimately driven by solar activity. The charged particles of the solar wind can disrupt satellite communications in space\, create auroral displays\, and interfere with telecommunications. At ground level\, magnetic fluctuations induce electric currents that can impact power grids\, pipelines\, and railway operations. Understanding these physical processes and their impacts requires improving our knowledge of all aspects of these solar-terrestrial interactions\, including the role played by subsurface geology. This talk will cover some recent multi-institutional work to better understand space weather risk in the UK. \nLecture given by Prof. John Mound\, University of Leeds\, School of Earth and Environment.

SUMMARY:Water on Mars - including the longest river in the solar system
DESCRIPTION:Water on Mars – including the longest river in the solar system. Lecture given by Professor Jeff Peakall\, University of Leeds\, School of Earth and Environment. \nAbstract \nWe will look at the history of water on Mars which is strongly linked to the main geological periods\, covering periods when channel networks flourished and flowed into deltas and oceans\, and others when giant outflow channels bigger and deeper than the Grand Canyon formed. We will then look at what evidence there is for water on Mars today. Some of the Martian channels are exquisitely preserved and we shall focus on the poster children for rivers on Mars\, the channels in Aeolis Dorsa. Yet despite being sold as the archetypal examples of rivers these channels can lay claim to be the strangest rivers in the solar system. As part of our exploration\, we shall also take a look at potential Earth based analogues such as giant submarine channels on ocean floors\, and inverted channels. \nTea and Coffee will be provided after the talk. \nPlease note the new venue – details are provided below.

SUMMARY:Ecosystem recovery following the Permo-Triassic mass extinction
DESCRIPTION:Ecosystem recovery following the Permo-Triassic mass extinction. Lecture given by Annabel Nichols\, University of Leeds School of Earth and Environment. \nThe Permo-Triassic mass extinction (PTME ~252Ma) was the most catastrophic biotic event of the Phanerozoic and recovery was protracted due to environmental instability through the Early Triassic. Although the PTME itself is well studied\, there is debate surrounding the nature and timing of marine ecosystem recovery in the aftermath of the extinction. It is argued whether ecological recovery occurred in a step-wise bottom-up manner\, with full recovery occurring contemporaneously with recovery of taxonomic diversity by the Anisian stage of the Middle Triassic (some 5-8 million years after the PTME)\, or whether Early Triassic communities recovered rapidly albeit with markedly different structure to pre-extinction ecosystems. We used lagerstätten data to track ecological recovery via snapshots of marine communities through the Triassic by modelling community structure and function. We show that marine communities recovered quickly in the aftermath of the PTME\, but Middle Triassic communities show a significant increase in diversity and vertical structure compared to Early Triassic communities. This suggests that alpha diversity as well as marine community structure and function recovered fully by the Middle Triassic\, in line with global taxonomic diversity\, but this recovery did not occur via a step-by-step rebuilding of marine ecosystems through the Early Triassic.

SUMMARY:Monitoring community exposures to volcanic emissions on Montserrat\, Eastern Caribbean.
DESCRIPTION:Rosie Lewis\, SEE\, University of Leeds. \n \nThe Soufrière Hills volcano releases around 440 tonnes of sulphur dioxide (SO₂) gas every day\, while ash deposits from past eruptions (1999-2011) are regularly disturbed by ash mining activities. This talk will present the first high-resolution study of how volcanic SO₂ and fine particles (PM2.5) are dispersed across the island\, leading to different levels of exposure in local communities. This research aims to help local authorities better understand their air quality\, assess potential health risks\, and explore the need for long-term monitoring. Rosie will share insights and photographs from her field expeditions to Montserrat\, offering a glimpse into the unique challenges of working around this active volcano.

SUMMARY:Relict periglacial geohazards in the United Kingdom.
DESCRIPTION:Relict periglacial geohazards in the United Kingdom. Speaker: Tom Berry\, Tunnelling and Ground Engineering\, Jacobs Ltd. \nAlmost all areas of the UK have been affected by periglaciation during the Quaternary and\, as such\, relict periglacial geohazards can provide a signiﬁcant technical and commercial risk for many civil engineering projects. The processes and products associated with periglaciation in the relict periglacial landscape of the UK are described in terms of their nature and distribution\, the hazards they pose to engineering projects\, and how they might be monitored and mitigated. A periglacial land systems classiﬁcation is applied here to show its application to the assessment of ground engineering hazards within upland and lowland periglacial geomorphological terrains. Techniques for the early identiﬁcation of the susceptibility of a site to periglacial geohazards are discussed. These include the increased availability of high-resolution aerial imagery such as Google Earth\, which has proved to be a valuable tool in periglacial geohazard identiﬁcation when considered in conjunction with the more usual sources of desk study information such as geological\, geomorphological and topographical publications. Descriptions of periglacial geohazards and how they might impact engineering works are presented\, along with suggestions for possible monitoring and remediation strategies.

SUMMARY:Seawater chemistry and mass extinctions
DESCRIPTION:Seawater chemistry and mass extinctions \nSpeaker: Dr Rob Newton\, School of Earth and Environment\, University of Leeds. \nAn image of a Sabkha environment from the middle east where we have modern day deposition of gypsum: Changes in the deposition of gypsum from the ocean through time play an important role in the story. \nThere are various lines of evidence that show that seawater chemistry has changed markedly through time\, but these records have multiple limitations and are generally have very low time resolution\, often with gaps of many millions of years. More recent approaches for a specific component of seawater\, sulphate\, establish a link between low concentrations of this ion and mid-Phanerozoic extinctions such as the Permo-Triassic and end-Triassic. Rob will explain the possible mechanism that links these phenomena which fits with the established framework of other correlations between ocean anoxia\, large igneous province volcanism and marine extinction\, based on carbon cycling in the oceans and marine sediments\, and particularly the generation of methane.

SUMMARY:Volcan Fuego de Colima (Mexico): Volcanological\, petrological and geochemical monitoring of the most active volcano in North America.
DESCRIPTION:Volcan Fuego de Colima (Mexico): Volcanological\, petrological & geochemical monitoring of the\nmost active volcano in North America. \nDr.Ivan Savov\, School of Earth and Environment\, University of Leeds. \n \nThe aim of my talk will be to introduce the geology and volcanology of young (Holocene) lavas and ash (tephra) deposits from the large Colima Volcanic Complex (CVC) in Western Mexico. I will be emphasising the chronological\, petrological and geochemical evolution of the currently active vent of Volcano Fuego de Colima (Mexico). The CVC has experienced numerous sub-Plinian to Plinian eruptions (better-known 1980 eruption of Mt.St.Helens in the USA or 1991 eruption of Pinatubo in the Philippines). CVC also developed at least 12 large calderas\, and produced the largest debris avalanche deposit on Earth. Many of these eruptions resulted in extensive ashfalls across vast areas of Mexico and beyond. Ashfall is a major volcanic hazard as it is causes roof and building collapse\, respiratory problems to humans and animals\, contaminates water supplies\, and causing widespread economic losses to the aviation industry. Importantly\, over the last couple of decades\, my collaborators and I have made a great progress in deciphering the Holocene eruptive history of this very active and highly explosive large stratovolcano. Some tantalising insights have come to light and we think those will be rather useful for future volcano monitoring and realistic hazard assessment of this dangerous andesitic volcano. \nPLEASE NOTE NEW VENUE: \nThe meeting will take place in the Maurice Keyworth Building (Lecture Theatre G.02) which\, due to the unavailability of the Michael Sadler\, will be our new venue for the foreseeable future. \nUntil we have used the venue\, we are not sure if we will be able to provide refreshments after talks. \nHow to get to the Maurice Keyworth Building: \nThe Maurice Keyworth Building (which some will know as the old Leeds Grammar School) is part of the Leeds University Business School and is found on the Western Campus which is on the west side of Clarendon Road opposite to the main campus. On entering the building go past reception and the lecture theatre (G.02) is on the left. \nMaurice Keyworth is about a 5–10 -minute walk from our old venue in the Michael Sadler Building but\, if travelling by car\, instead of using the Orange Zone parking\, there is the possibility of parking closer on surrounding roads. These are: \nLyddon Terrace: Although surrounded by university buildings\, is a public road and has no parking restrictions. It is accessed off Clarendon Road via University Road\, turning right before the barrier. Woodsley Road (off Clarendon Road) and St Johns Terrace: (off Moorland Road) Both have unrestricted parking after 6.00 pm on the side bordering the campus (permit parking only on sides with houses) \nBlue badge holders: Park in the Western Campus parking facilities (accessed off Clarendon Road) where there are spaces before the barrier. If these are all occupied then contact Security via the speaker on the barrier\, state your business\, and they will raise it. Exit is via the one-way system onto Moorland Road. \nMaurice Keyworth Building is No. 19 (Business School\, Maurice Keyworth Building) \nLocation specifics: \n\nOS grid reference = SE 29023 34712: Click here for a map.\nGoogle Plus Code = RC5Q+5J Leeds.

SUMMARY:Recent Sea level Change\, Dr Graham Rush
DESCRIPTION:Recent Sea level Change\nDr Graham Rush\, Research Fellow\, School of Earth and Environment\, University of Leeds \n  \nDuring deglaciations melting ice sheets cause a global mean sea-level rise. However\, sea-level rise is not even across the oceans. Some regions experience a greater than average rise and others experience less\, or even a sea-level fall\, dependent on the source of the melting ice. Due to its position relative to the major ice sheets\, the rate and magnitude of sea-level change in the North Sea is particularly sensitive to the location of melting ice. In this talk I will discuss the processes that cause this pattern of uneven sea-level change. I will subsequently present sea-level reconstructions from the North Sea basin for two different time periods during the Quaternary and discuss how these sea-level reconstructions make it possible to locate the source of the melting ice at specific time periods and how this in turn enables us to better understand the future stability of ice sheets and also the climate/ocean response to melting ice sheets. \n  \nPLEASE NOTE NEW VENUE: \nThe meeting will take place in the Maurice Keyworth Building (Lecture Theatre G.02) which\, due to the unavailability of the Michael Sadler\, will be our new venue for the foreseeable future. \nUntil we have used the venue\, we are not sure if we will be able to provide refreshments after talks. \nHow to get to the Maurice Keyworth Building: \nThe Maurice Keyworth Building (which some will know as the old Leeds Grammar School) is part of the Leeds University Business School and is found on the Western Campus which is on the west side of Clarendon Road opposite to the main campus.

SUMMARY:Exceptional Preservation of Dinosaur Eggs and Embryos from the Cretaceous of China and Argentina. Dr John Nudds\, Manchester University
DESCRIPTION:Exceptional Preservation of Dinosaur Eggs and Embryos from the Cretaceous of China and Argentina. Dr John Nudds\, Manchester University \n \nDinosaur eggs have been known for almost 100 years\, but it is still exceptionally rare to find eggs containing any remains of their tiny embryos. I have been directing an international team of specialists which has used ground-breaking techniques to reveal these delicate fossils. Embryos from China have been identified with the enigmatic group of dinosaurs\, the therizinosauroids\, and the embryos have revealed much about the anatomy and affinities of these peculiar animals. Those from Argentina proved to belong to the titanosaurs\, some of the largest dinosaurs ever to have walked on Earth. Their tiny skulls\, not much more than a centimetre in length\, have revealed some surprises! \nJoining instructions: \nNon-members are welcome to join the talk\, which will be delivered via Microsoft Teams. To obtain the joining link\, Email the LGA Secretary (lga.sec@btinternet.com) no later than 24 hours before the talk is due to start. \nThe joining link will be sent out on the day of the talk.

SUMMARY:Volcanoes from Space: satellite measurements of magma.    Dr Susannah Ebmeier Leeds University SEE
DESCRIPTION:Dr. Ebmeier investigates different aspects of volcanic activity using satellite remote sensing. In particular\, she studies the physical processes that control the character of volcanic activity\, including magma storage\, edifice growth & collapse\, and volcanic interactions. An important aspect of the research using satellite imagery is exploring how it can be made useful for volcano monitoring and assessing volcanic hazards. The impact of volcanic gases on the Earth’s environment is also part of the research. \nPlease note\, this meeting will be virtual meeting held via Microsoft Teams.

SUMMARY:A Re-evaluation of Glacial Lake Pickering
DESCRIPTION:During the Quaternary\, repeated glacial cycles left widespread deposits across Britain. These deposits hold an archive of terrestrial responses to changes in climate over the last 2.6 Ma. One such archive is the Vale of Pickering in North Yorkshire: a low-lying depression bounded on all sides save the east end by large hills comprised of Jurassic and Cretaceous bedrock. During the Late Quaternary\, this natural basin was blocked by ice sheets forming large proglacial lakes. To understand the advance and retreat of the surrounding ice lobes in the Vale of York to the west and the North Sea Lobe to the east -the deposits of the Vale of Pickering are crucial; however\, limited work in the area has failed to ascertain an accurate history of Lake Pickering. Using newly available high-resolution LiDAR data\, field observations\, historic borehole records\, and optically stimulated luminescence (OSL) dating\, a new chronological model for Lake Pickering has been established. This shows that 1) previously estimated lake levels are too high and that during the LGM\, Lake Pickering was no more than 33 m O.D. 2) Ice invaded the eastern coast of the Vale of Pickering on more than one occasion\, potentially earlier than the LGM. 3) Several iterations of Lake Pickering exist with a lake during the LGM\, but at least one older than 30 ka. 4) The drainage of Lake Pickering is very complex and seaward drainage likely prevailed until the eastern end became blocked by continued deposition of glacial material. This reversed the drainage through the Kirkham Gorge. 5) The use of newer geoscientific techniques like OSL and LiDAR mapping are crucial to the understanding of the palaeoenvironment of the Vale of Pickering and the continued development of these techniques are vital to further work. \nThis talk will be delivered via Microsoft Teams. Joining instructions will be circulated to members nearer the date. Non-members are welcome to attend and should email the Secretary at lga.sec@btinternet.com no later than 24 hours before the scheduled start time\, to request joining instructions.
