The Dinosaur Resurrection


Speaker: Dr Daniel Field

Date: February 19th 2019 (Tuesday)

Type: Talk (Evening)

Summary: How modern birds rose from the ashes of an asteroid. Talk commences at 20:00 in Winch Room.

More info:

Birds are the most diverse group of terrestrial vertebrate animals, with nearly 11,000 living species. But how did this incredible diversity arise? In this talk, we will investigate how the asteroid impact that eliminated the giant dinosaurs influenced the evolutionary history of birds—the only living dinosaurian descendants. birds_on_fire.pdf

Where
Wynstones School, Stroud Road, Whaddon, Gloucester (map)
Description
The Geology of Eruptions, Earthquakes and Tsunamis  
Three of the most devastating natural disaster-forming events are geological, all related to plate tectonics, and are very difficult, if not impossible, to accurately forecast.  What are the causes of these events and their various manifestations? Why are some more dangerous than others? How can we prevent or mitigate these effects? Examples of some of these phenomena will be used to illustrate these points Monday 7th for 10 weeks (not 18h Feb) until 18th March.

Richard has worked in micropalaeontology and stratigraphy for nearly 30 years. His professional career started as a palynologist for Kingston Geological Services working on North African petroleum basins. Following a period of doctorate research, he moved to Indonesia where he was a stratigrapher and consultant for Robertson Research and Core Laboratories analysing and advising on petroleum basin stratigraphy of South-east Asia. In 2012, he moved to the Sultanate of Oman where he was appointed Head of Stratigraphy for a leading petroleum exploration and development company.


Richard returned to Dorset last year and has established Chalk Newton Geoscience, a Dorset-based specialist geological advisory and education company.


Richard received a B.Sc. degree in Geology and MSc degree in Micropalaeontology from the University of Southampton and a Ph.D. degree in Dinoflagellate (Palaeo)ecology from the University of Westminster. 


This is the second of a series of Earth Science-based lectures organised by DGAG in collaboration with other groups.

Course - Advances in Understanding Earth’s Structure and Operation
When
Thu, 14 February, 19:30 – 21:30
Where
The Chantry, Thornbury. (map)
Description
Advances in Understanding Earth’s Structure and Operation. 
This 10 week course aims to introduce you to relatively new ideas, some accepted, some controversial, about the internal structure and tectonics of the Earth. Many ideas have changed radically since the inception of the Plate Tectonic hypothesis, and especially in the period from the 1990s, partly as a result of new technology, and the re-examination of parts of the theory that evidence did not support. Each week we will examine a different topic, such as subduction, mantle dynamics, mantle plumes.   Held at The Chantry, Thornbury.  First meeting 7.30 – 9.30, Thurs 10th January until March 21st (not Thurs 21st Feb). Cost £75

NEAPOLITAN VOLCANOES


An interesting blog

An Interesting Blog

A correspondent has brought THIS BLOG to my attention and it is well worth a look. 

The latest entry is a review of last years earthquakes and the conclusion is that 2018 was an entirely "normal" seismic year. And he has the statistics to prove it!

The post which I found most interesting was THIS ONE linking earthquakes and volcanism in last years activity in Hawaii. There is an interesting video showing the many small earthquakes. It is best seen in the blog but the following gives you a flavour. (Sorry for the crappy quality but this is the first time I have tried to put a video onto the blog and I am finding it difficult. Now if only he had put it on YouTube...)

Brazilian tailings dam collapse

Brazilian Tailings Dam Collapse

Much has been written about this. HERE is the best video I have come across. If you speak Portuguese you will get more out of it but even without it is horrifying. The most terrifying thing is that there is no warning - the hillside starts moving. THIS PAGE gives much more information.

THIS PAGE shows some photos of the aftermath

Bristol University - Inaugural Lecture
When
Wed, 6 February, 17:30 – 19:30
Where
Wills Memorial Building, Reception Room, Queens Road, Bristol, BS8 1RJ (map)
Description
Joachim Gottsmann, Professor of Volcanology, delivers his Inaugural Lecture. Introduction by Prof. Jens Marklof, Dean of the Faculty Science, University of Bristol

Title: Mechanism of volcanic unrest: a tale from four continents

Abstract: Volcanic unrest comes in many forms including anomalous earthquake activity and ground deformation. Unrest can be a prelude to future eruption but fingerprinting the mechanisms behind unrest and forecasting its outcome remains challenging. Here Professor Gottsmann presents insights from studies across the globe to unravel some enigmatic internal workings of volcanoes.

There will be a drinks reception following this event.

Description

LIMESTONES, MICROBES, VIRUSES

MAURICE TUCKER

School of Earth Sciences, University of Bristol

Carbonate rocks, that is limestones and dolomites, are a feature of the sedimentary record, right back to the oldest strata (~4200 Ma old). Common types are skeletal-bioclastic-reefal limestones, oolites (like the Bath stone) and microbialites (like the Cotham Marble). Although the roles of bacteria are well known in the formation of stromatolites, totally ignored is the possibility that viruses may be involved in limestone deposition. Viruses are everywhere, in greater abundance than bacteria, but dependent upon them. New evidence from modern microbial mats and from lab experiments is showing that viruses can be permineralised and can influence carbonate precipitation. Could viruses provide the seeds for limestone formation?  This talk explores the potential role of viruses in carbonate precipitation. Viruses are the new frontier in Earth Science ……
