Stable Isotope Facility

BGS Science Facilities – Centre for Environmental Geochemistry

banner_stable_isotope

We are a node of the National Environmental Isotope Facility (NEIF) and employ a wide variety of stable isotope methodologies in environmental change, pollution, hydrology, and human-landscape interactions research.

We focus on the environment, in particular climate change and human-landscape interactions, with increasing importance on the Anthropocene and the modern calibration period. We also use stable isotopes as tracers of modern pollution and to better understand the hydrological cycle, especially in areas suffering from significant human impact. We work with the UK higher education institutes community and international partners to deliver research, method development and training.

As part of NEIF, the Stable Isotope Facility analytical capabilities and technical expertise can be accessed (free at the point of access) by UK researchers via an application to one of NEIF’s steering committees. We also welcome to opportunity to collaborate via other research funding streams such as NERC Standard or Large Grant applications or via direct access/commercial routes.

Capability

We are the largest UK producer of stable isotope data, particularly specialising in climate, environmental, and archaeological studies. We undertake high precision 2H/1H, 13C/12C, 15N/14N, 18O/16O, 30Si/28Si, and 34S/32S analysis, at natural abundance levels, of a wide range of sample materials, including waters, carbonates, silicates, organics, N & S compounds, phosphates, and methane. The laboratory has eleven gas-source isotope ratio mass spectrometers that are supported by adaptable ‘off-line’ preparation methods, with access to four high vacuum gas preparation lines, alongside state-of-the-art, fully automated ‘on-line’ techniques.

We specialise in the study of geochemical processes in the hydrosphere and atmosphere, with particular strength in 15N/14N and 34S/32S analysis of a wide variety of compounds associated with nutrient transfer and pollution in the global nitrogen and sulphur cycles. 18O/16O analysis of nitrates, phosphates and sulphates, which can provide valuable additional information on these environmentally important species, has now been added as a routine capability.

Our fluorination 18O/16O and 30Si/28Si analysis of diatoms and other opaline forms of silica is a unique capability in the UK, and one of only a handful of laboratories of its kind in the world.

For archaeological research, we specialise in triple 13C/12C, 15N/14N and 34S/32S methods in palaeodietary studies; and in addition, we have the capability to analyse 18O/16O on a wide range of material (including both phosphate and carbonate analyses of bioapatite). The wider facility’s combined 18O/16O and 87Sr/86Sr capability is especially valuable in studies of archaeological migration.

Materials we analyse include:

  • Waters: 2H/1H and 18O/16O of marine and fresh waters, fluid inclusions (following microlitre extractive methods), and soil/plant materials (following vacuum distillation)
  • Carbonates: 13C/12C and 18O/16O of microfossil and other pure calcium carbonates (down to 5 micrograms), impure carbonates, and aqueous bicarbonate
  • Silicates and phosphates: 18O/16O and 30Si/28Si of rock minerals, biogenic silica, and tooth/bone materials.
  • Organic materials: 2H/1H, 13C/12C, 15N/14N, 18O/16O, and 34S/32S of bulk organic materials (plants, soils, etc.)
  • Nitrogen and Sulphur compounds: 15N/14N, 34S/32S, and 18O/16O of nitrate, ammonium, sulphate, sulphide, and organic nitrogen and sulphur
  • Phosphate: 18O/16O of phosphate from soils, sediments and teeth
  • Methane: 13C/12C and 2H/1H in gas and water samples

The Stable Isotope Facility has eleven isotope ratio mass spectrometer systems:

  • GV Isoprime with EuroPyrOH for analysis of water 2H/1H in marine and fresh waters, fluid inclusions, soil/plant materials
  • Isoprime 100 with AquaPrep for analysis of water 18O/16O in marine and fresh waters, fluid inclusions, soil/plant materials
  • Isoprime 100 with MultiPrep for analysis of 13C/12C and 18O/16O of single microfossils
  • Isoprime precisION with isoFLOW for analysis of 13C/12C and 18O/16O of aqueous bicarbonate
  • GV Isoprime with MultiPrep for analysis of 13C/12C and 18O/16O of microfossil and other pure calcium carbonates
  • VG Optima for analysis of 13C/12C and 18O/16O of impure carbonates and aqueous bicarbonate
  • Isoprime precisION with vario ISOTOPE cube for analysis of 13C/12C, 15N/14N and C/N of bulk organic materials (plants, soils, etc.)
  • Thermo Finnigan DeltaplusXL with oxidative and reductive elemental analysers for analysis of nitrogen and sulphur compounds: 15N/14N, 34S/32S, and 18O/16O of nitrate, ammonium, sulphate, sulphide, and organic N and S as well as 2H/1H, 13C/12C, 15N/14N, 18O/16O, and 34S/32S of bulk organic materials (plants, soils, etc.)
  • Thermo Finnigan MAT 253 with manifold for analysis of 18O/16O and 30Si/28Si of rock minerals, biogenic silica, and tooth/bone materials
  • Thermo Finnigan IsoLink Elemental Analyser linked via continuous flow to a Delta V Isotope Ratio Mass Spectrometer. The IsoLink combines both oxidative combustion, and high temperature reductive pyrolysis and utilises helium management to enable very high precision analysis on a variety of matrices for O/H and C/N/S. The technology allows triple analysis of CNS on small sample sizes at high precision.
  • Sercon Cyroprep for the analysis of 13C/12C and 2H/1H of methane from high to atmospheric concentrations in both gas and water samples.

May 2020: Meet the isotope hunters: Part 2

In this post, Dr. Andi Smith and Dr. Jack Lacey will continue to explain their work as “Isotope Hunters” for environmental investigations and we will see how the answers provided by isotope fingerprints are powerful tools supporting academics and policymakers in their fight against high levels of pollution in air, water and soil and delivering them information on past climate.

May 2020: Meet the isotope hunters: Part 1

In many countries, institutions are investigating ways to detect and measure pollution levels, allowing regulatory bodies to implement preventive actions to limit the negative effect of pollution on the air, land, and water, and their associated risks for human and environmental health. In environmental investigations that seek to understand climate change or pollution sources, isotope fingerprints can provide a unique insight into the origin or production of a sample material, providing a strong supportive tool for investigators. One such laboratory is the National Environmental Isotope Facility based at the British Geological Survey in Nottingham (UK), where the “Isotope Hunters” have been providing expert support for environmental research. In this series of posts, we want to better understand the work of “Isotope Hunters” for environmental investigations. For this reason, we interviewed Dr. Andi Smith and Dr. Jack Lacey, who will be discussing the work they carry out on environmental change within their specialty of stable isotope geochemistry.

March 2019: Isotopes in Biogenic Silica group

Congratulations to Jack Lacey for being invited to be a convenor of the working group: Isotopes in Biogenic Silica (IBiS). The study of biogenic silica (silica deposited in plants, algae and animals) in Quaternary sediments is currently being revolutionised by technical advances in stable-isotope mass spectrometry, ICP–MS and 32Si dating. Growing interest in the global biogeochemical cycle of silicon and its coupling with the carbon cycle is evident from an upsurge of papers, while a wide range of disciplines including physiology, ecology, geochemistry, hydrology, geomorphology, pedology, agronomy, forestry, limnology, oceanography and biogeochemical modelling has begun to focus on processes involving biogenic silica in the modern environment.

December 2019: Suigetsu, Sediment and Silica: Embarking on my PhD: by Charlie Rex

Anyone who has started researching something new is well aware of the challenges involved: vast amounts of literature, creating sensible hypotheses and selecting a suitable methodology (among other hurdles!). For new PhD students, this can also involve a totally new setting, such as a new city, country, or continent. Thankfully I didn’t have to move continent, but I did make the move to Scotland and start fresh on a PhD topic that I found fascinating and unfamiliar in equal measure. Though this was daunting, I am incredibly fortunate to be surrounded by a multidisciplinary, multi-continental academic network who have helped me get off to a good start! Find out more about Charlie’s experience below.

This summer, Melanie Leng (BGS’s Chief Scientist for Environmental Change Adaptation) attended a workshop in Dar es Saleem, Tanzania, with around 70 other scientists from 10 countries, with the aim to form a plan to create a palaeo Geo–Observatory in this region. The Geo–Observatory, in the form of a long sediment core, will contain information on past conditions in Lake Tanganyika and tropical East Africa. Here Melanie tells us about why we need to do research in this region and what happens next.

March 2019: Homeward Bound: Last Leg of the ORCHESTRA Cruise (Part 4)… by Carol Arrowsmith

We were at sea for around eight weeks on the RRS James Clark Ross, undertaking the ANDREXII transect. We set off from the Punta Arenas, Chile, calling in at the Falklands before crossing the Drake Passage to the tip of the Antarctic Peninsula at 60oS, and then out along over 3000 miles to the Indian Ocean at 30oE. Find out more from Carol below.

March 2019: Prehistoric Britons rack up food miles for feasts near Stonehenge

A collaboration between BGS (Angela Lamb, Jane Evans and Hilary Sloane) and scientists from Cardiff University, University of Sheffield and University College London has provided evidence of the earliest large-scale celebrations in Britain – with people and animals travelling hundreds of miles for prehistoric feasting rituals. The study, led by Dr Richard Madgwick of Cardiff University, is the most comprehensive to date and examined the bones of 131 pigs, the prime feasting animals, from four Late Neolithic (c. 2800-2400BC) complexes. Serving the world-famous monuments of Stonehenge and Avebury, the four sites – Durrington Walls, Marden, Mount Pleasant and West Kennet Palisade Enclosures – hosted the very first pan-British events, feasts that drew people and animals from across Britain. The isotope results show pig bones excavated from these sites were from animals raised as far away as Scotland, North East England and West Wales, as well as numerous other locations across the British Isles. The study, ‘Multi-isotope analysis reveals that feasts in the Stonehenge environs and across Wessex drew people and animals from throughout Britain’, was funded by the British Academy and NERC and is published in Science Advances.

March 2019: Full steam ahead with the sampling on the RRS James Clark Ross: ORCHESTRA Part 3… by Carol Arrowsmith

We are now cruising along the 60oS latitude, having crossed the Drake Passage, passing Elephant Island (off the tip of the Antarctic Peninsula), between Coronation and Laurie Island and are now out in the Weddell Sea at approximately 23oW. This leg of the ORCHESTRA hydrographic/tracer section covers the northern rim of the Weddell Gyre and is called ANDREXII (Antarctic Deep Water Rates of Export). This leg was previously sampled 10 years ago so we are interested to see the difference global warming has made to the ocean. Carol is half way through a research cruise across the Weddell Sea as part of ORCHESTRA.

March 2019: Tropical palaeoclimate meeting as temperatures break records in the UK… by Heather Moorhouse

In 2018, the UK NERC-funded collaborators of the International Continental scientific Drilling Program – DeepCHALLA project met in Cambridge amidst a Siberian blast, known as the ‘Beast from the East’, as temperatures plummeted and ice and snow disrupted UK travel. In 2019 however, the scientists met in tropical Lancaster, during maximum temperature records for the month of February. It is predicted that weather events will be increasingly unpredictable, variable and extreme, and the temperature differences between our two meetings merely serves to highlight the future under climate change.

March 2019: From Chile to the Falklands and beyond: ORCHESTRA Part 2… by Carol Arrowsmith

I left the UK last Saturday and flew to Punta Arenas in Chile. There we waited (with various, BAS, NOC and university colleagues) to board the RRS James Clark Ross; a few days later we departed for the Falkland Islands. On board our first task was to lash down all the equipment in the ship’s laboratories needed for our sampling and familiarise ourselves with the layout of the ship. We have been accompanied for most of the journey so far by a variety of birds and mammals, including magnificent black-browed albatross, that mostly just sit in the water surrounding the ship waiting for food (to upwell from beneath the ship).

Dr Barry Lomax and Prof Melanie Leng are isotope geochemists who work on understanding how the isotopic composition of environmental materials can tell us about past environments. Here they blog about their new paper, available via open access in the premiere geochemistry journal (Geochimica et Cosmochimica Acta), co–authored by Dr Janice Lake and Dr Phillip Jardine on the use of carbon isotopes in plant materials to predict atmospheric CO2. The paper sets out to test this relationship to determine if it could be used as a tool for estimating changes in atmospheric CO2 concentrations through geological time.

June 2019: Congratulations to Elizabeth Atar on the successful defence of her PhD thesis entitled ‘Late Jurassic Sedimentation in the Boreal–Tethyan Seaway: climate modelling, geochemistry, and petrography of the Kimmeridge Clay Formation’

Climate exerts a strong influence on sedimentation. Understanding the processes behind the spatial and temporal heterogeneities in sedimentary successions can, therefore, be used to reconstruct climate processes in the geological past. Deposited across >1000 km in northwest Europe in the shallow (< 200 m), epicontinental Laurasian Seaway, the Kimmeridge Clay Formation provides an exceptional opportunity to study climate processes and their effect on sedimentation at different latitudes through the Late Jurassic (Kimmeridgian–Tithonian). This thesis presents independent climate modelling, sedimentological, and geochemical datasets from three time–equivalent sections, spanning 1 million years, in the northern and southern extents of the Laurasian Seaway (30–60°°N palaeo–latitude) in order to investigate climate dynamics and controls on sedimentation at different northern hemisphere latitudes in the Late Jurassic. The climate modelling results yield two different hypotheses: 1) HadCM3L indicates that an expanded Hadley Cell and migrated intertropical convergence zone resulted in tropical conditions over the Laurasian Seaway, whereby organic carbon-enrichment in sediments was promoted through enhanced nutrient supply resulting from continental weathering and erosion, and 2) FOAM suggests subtropical–temperate conditions prevailed and that organic carbon enrichment was driven by wind–driven upwelling of nutrient–rich water.

Sedimentological and geochemical analyses for the Ebberston 87 Core, drilled in the Cleveland Basin (Yorkshire, UK), indicates depositional conditions fluctuated between three distinct states and that alternations of organic carbon–rich, carbonate–rich, and clay–rich mudstone and redox conditions were driven by the expansion/migration of the intertropical convergence zone. Analysis of the Swanworth Quarry 1 Core, drilled in the Wessex Basin (Dorset, UK), reveals that although depositional energy differed between the Cleveland and Wessex Basins, sedimentation in both basins was driven by the same, over–arching tropical climate control. Analysis of a third core, drilled in Adventdalen (Svalbard), demonstrates that organic carbon–rich sedimentation occurred in a deltaic setting, which had a markedly higher depositional energy. While the depositional environments in the northern and southern sectors of the Laurasian Seaway differed substantially, similarities between the three studied sections, namely cyclical deposition of terrestrial organic carbon–rich and detrital–rich sedimentation, integrated with published data from throughout the seaway, suggest a low–latitude, tropical influence on sedimentation and organic carbon enrichment across the entire Laurasian Seaway. Furthermore, the palaeogeographic setting of the Laurasian Seaway made the sedimentary system sensitive to subtle changes in weathering and water depths, resulting in distinct modes of sedimentation and biogeochemical cycling.

June 2019: Congratulations to Katrina Kerr on the successful defence of her PhD thesis entitled ‘Reconstructing the Indian Summer Monsoon response to global climate change’

The Indian Summer Monsoon, a subsystem of the Asian Monsoon, is one of Earth’s most dynamic expressions of oceanic–atmospheric–terrestrial processes affecting some of Earth’s most densely populated regions. Therefore, it is imperative to have a comprehensive understanding of the Indian Summer Monsoon in order to understand how its behaviour may be manifested by anthropogenic induced climate changes. Reconstructing how the monsoon behaved in the past presents an opportunity to disentangle its sensitivities to a range of forcing parameters (e.g.ice volume) during periods of differing climatic states.

However, understanding of how the Indian Summer Monsoon behaved in the past has been limited both spatially and temporally, further constrained by discrepancies among climate proxy records. This work fills both a temporal and spatial gap in our knowledge of the past behaviour of the Indian Summer Monsoon. High–resolution (millennial to centennial scale) records of Indian Summer Monsoon induced river runoff and surface freshening from the core convective region of the Indian Summer Monsoon, the northern Bay of Bengal and Andaman Sea, have been generated from 70 to 140 thousand years ago. These records provide an insight into how the Indian Summer Monsoon responded to the penultimate deglaciation (Termination II), the subsequent warmth of the Last Interglacial Period and ensuing oscillations between the warm interstadial and cold stadial periods of Marine Isotope Stage 5. These records are compared with both high–latitude and low–latitude climate records in order to understand how the monsoon responded to changes in Earth’s internal climate system and the influence of external preconditioning
