- Principles and Practice of Stable Isotope Geochemistry in Earth and Environmental Geosciences
The aim of this short course is to allow PhD students (non–experts) to gain an understanding of the use of stable isotopes in Earth and environmental geosciences, through lectures, workshops and hands–on lab work. At the end of the 2 days the participants should be able to:
- Have an understanding of the general principles of isotope geochemistry including notation and standardization.
- Understand the water/meteorological cycle in particular how rainfall isotope composition are determined by climate, how O, H, and C stable isotope compositions in the modern day waters provide a framework for the interpretation of these isotopes in the past archived in geological materials.
- Understand the application of stable isotope geochemistry (O, H, C and S) to a variety of geological settings, including volcano-magmatic systems, ore deposits and geothermal systems.
- Gain knowledge on the global cycles of C, N and S.
- Understand how isotope data are interpreted in terms of climate/environment from some of the most common archives, including lakes, trees, oceans, speleothems, archaeological materials and from deep time geological successions.
- Understand how N, C, S and H isotope analysis of biological tissues can be utilised to elucidate food webs and animal migration.
- Understand how isotopes (N, O) can be used to trace nutrient cycles within both aquatic and soil systems and in doing so inform us about sources of environmental pollution and past environmental change. Laboratory practicals will allow participants to gain experience and knowledge of mass spectrometry and how isotope data is acquired. These will be tailored to delegate’s own areas of interest after acquisition of the basics of stable isotope geochemistry. A full tour of SUERC isotope laboratories will be included in the course.

- Dr Artemios Oikonomou, a Marie Curie post–doctoral fellow in Archaeology at the University of Nottingham (working with Prof Julian Henderson, UoN, and Dr Simon Chenery, BGS) will be presenting research on ancient glass at the European Association of Archaeologists meeting.
- Date & Location: 30th August–4th September in Vilnius, Lithuania
- Background: Investigation of glass objects from Dodona Sanctuary, Epirus, Greece: an interdisciplinary approach. Dodona Sanctuary was the major religious centre of north–west Greece, in the Epirus region, connected with the cult of Zeus Dodonaios and his wife Dione. According to ancient Greek tradition it is considered to be the oldest oracle in ancient Greek world. Archaeological evidence has confirmed continuous habitation from the Bronze Age (2600–1100 BC) to the end of the 4th c. AD. The Dodona Sanctuary flourished during the Hellenistic period and especially during the reign of King Pyrrhus when major reconstruction works took place. The Dodona Sanctuary played an important role as a political, administrative and religious centre during that period and its relationship with regions outside Greece, like Alexandria in Egypt, is well attested both archaeologically and historically. Our presentation will focus on glass found in the excavations of Prytaneion and Vouleutirion which were the major political buildings at the Dodona Sanctuary. Our primary research objectives are: (1) to suggest the raw materials used to make the glasses; (2) identify any compositional contrasts between middle and late Hellenistic glass; (3) to suggest a provenance for the glass by comparing our results with other published datasets – especially whether compositions suggest both a Levantine and a non–Levantine provenances. Here we present results form 40 samples that we have analysed using SEM/EDX and LA–ICPMS analysis. The assemblages from which samples were taken consists of fragments of various vessel types (core formed vessels, ribbed bowls, cast bowls, conical engraved bowls) of a variety of colours (deep blue, olive green, green, amber, colourless). According to the chemical analyses, the glass from Dodona is a typical soda–lime–silica type with added mineral salts (natron) as a flux. Its chemical compositions are homogeneous. Small differences in various major, minor and trace elements between individual samples suggest the use of different types of raw materials and also different production zones. A comparison of these glass chemical compositions with contemporary glass artifacts thus gives new insights into the production and distribution of glass used in Greek region during the Hellenistic period.
A workshop on stable isotopes in fossils and organic compounds from lake sediment records
- Date & Location: 28th & 29th of July 2016 at the University of Southampton, UK
- Background: Stable isotopes (with a focus on the lighter elements H, C, N, O, and S) can be measured on sedimentary remains of plants and animals. The beauty of this is that taxon–specific (identified) remains and individual compounds can be measured rather than bulk sediments. We currently witness a step–change in understanding stable isotope signals in sedimentary records, as it has become possible to link stable isotope values of remains and compounds to explicit provenances. For example, it allows the study of carbon cycling in well–defined ecosystem components over time; it provides insights in food web structure by analysing remains of organisms at different trophic levels in the food web and how they respond to each other and external drivers; it allows the study of palaeohydrology/palaeoclimatology using organisms that live in known habitats, thus identifying signal and reducing noise compared with bulk sediment palaeoenvironmental stable isotope records. Apart from highlighting potential new directions in stable isotope studies, this workshop will also address issues concerning analytical precision and reproducibility and the need for modern datasets to calibrate downcore studies.
- Workshop aims: The aim of this workshop is to clearly formulate the research areas where stable isotope techniques can make most impact. To do so the workshop will bring together those colleagues (both senior and early career scientists) that have been pushing the boundaries of stable isotope methodologies and applications over the past years and (1) provide a state–of–the–art overview of latest developments in the field, (2) identify key issues for this emerging field and a way to address these in the next years, and (3) stimulate knowledge exchange, reaching out especially towards early career scientists and scientists from developing countries. Workshop output will be a review article on this topic in the Journal of Paleolimnology that could be part of a special issue if enough interest exists.
- Keynote speakers: Prof. Oliver Heiri (University of Bern, Switzerland), Prof. Melanie Leng (University of Nottingham & British Geological Survey, UK), Dr. Jessica Whiteside (National Oceanography Centre, Southampton, UK), Prof. Mat Wooller (Alaska Stable Isotope Facility, University of Alaska Fairbanks)

- Shale Gas and Fracking: the Politics and Science
Hear from all sides of the fracking debate with this free online course. Understand what shale gas is and why it divides opinion… Shale gas is seen by many as a cheap, clean and plentiful source of energy; a low-carbon ‘game changer’ helping us meet the world’s rapidly growing demands for energy and offering greater energy security. Its rapid rise has not been without controversy, however. Earth tremors, surface and groundwater contamination, and the effects of fracking on human and animal health are all high profile concerns. During this four-week course, we’ll study the politics, economics, and science of shale gas. We’ll examine how shale gas was formed, and how we extract it through hydraulic fracturing, or ‘fracking’. We will look at the impact of shale gas on energy markets and energy security. We then move on to the environmental politics of shale. What are the local effects in terms of water contamination, seismic activity, and air pollution? What are the global effects? Does shale gas offer a ‘bridge’ to a low-carbon future, or would we be walking the plank? Finally we look at the question of what the public thinks, an area where the University of Nottingham has particular expertise, having run a public opinion survey on shale gas since 2012. Why are the US and UK experiences so different? What do the public think of allowing unconventional gas to be developed? At the end of the course you will have improved you understanding of the costs and benefits of shale gas, and you will have made your contribution to the public debate on this important topic.

- AGU Fall Meeting Session: Isotopes in Biogenic Silica
This session focuses on recent developments in isotopes in biogenic silica (BSi) (including diatoms, phytoliths, sponge spicules, radiolaria and chrysophytes). The development of these proxies provides important constraints on paleoreconstructions over a range of temporal and spatial scales and we welcome abstracts that cover all aspects of this advancement, including methodological and analytical practices. The session will cover studies that use either stable (e.g., δ18O, δ30Si, δ66Zn and δ13C, δ15N in organic inclusions) or radiogenic isotopes (e.g., δ32Si, δ14C) as tracers of environmental change and biogeochemistry (e.g. precipitation, temperature, nutrient utilization). In particular we encourage contributions focusing on methodological developments as well as contemporary studies from field and laboratory experiments, which are essential in order to constrain the interpretation of paleoreconstructions.
