Research article 01 Dec Correspondence : Ian Cartwright ian. Peatlands are a distinctive and important component of many upland regions that commonly contain distinctive flora and fauna which are different from those of adjacent forests and grasslands. Peatlands also represent a significant long-term store of organic carbon. While their environmental importance has long since been recognised, water transit times within peatlands are not well understood.

High-energy cosmic rays shower the Earth’s surface, penetrating meters into rock and producing long-lived radionuclides such as Cl, Al and Be Production rates are almost unimaginably small – a few atoms per gram of rock per year – yet we can detect and count these “cosmogenic isotopes” using accelerator mass spectrometry, down to levels of a few thousand atoms per gram parts per billion of parts per billion! The build-up of cosmogenic isotopes through time provides us with a way to measure exposure ages for rock surfaces such as fault scarps, lava flows and glacial pavements.
Where surfaces are gradually evolving, cosmogenic isotope measurements allow us to calculate erosion or soil accumulation rates. This site explains some of the background to our work and provides an overview of cosmogenic isotope research at the University of Washington. It also serves as a repository for data generated by the group, descriptions of our lab procedures, technical information and calculation methods.

Introduction to Water Dating and Tracer Analysis
Each cell of the IPTEI provides the chemical name, symbol, atomic number, and standard atomic weight of an element. Color-coded pie charts in each element cell display the stable isotopes and the relatively long-lived radioactive isotopes having characteristic terrestrial isotopic compositions that determine the standard atomic weight of each element. An element-by-element review accompanies the IPTEI and includes a chart of all known stable and radioactive isotopes for each element.
Practical applications of isotopic measurements and technologies are included for the following fields: forensic science, geochronology, Earth-system sciences, environmental science, and human health sciences, including medical diagnosis and treatment. While the familiar Periodic Table indicated similarities of chemical element properties terms that appear in the text in bold font appear in a glossary in Section 5 , the IPTEI emphasizes some of the unique properties of each element.
It is intended to familiarize students, teachers, and non-professionals with the nature and properties of isotopes of the chemical elements.

Photographer: Kate Clark. Now she is part of the earthquake geology team at GNS Science. They want to know where, how often and how big past earthquakes were. The Hikurangi subduction zone lies just off the East Coast where the Pacific plate is moving down under the Australian plate. She takes cores of old sediments from coastal lagoons and studies the changes in microfossils back through time. She does this to find evidence for the land moving vertically and the tsunami inundation that happens in large earthquakes.
Radiocarbon dating helps her work out how old the past events are. No one knows when earthquakes will occur but scientists try to predict how often different sized earthquakes happen. This research is ongoing, however a summary report is due out in mid

FossilFriday – with the Bluff oyster season ending on Monday, we thought you might like to see a fossil of the now extinct giant oyster, Flemingostrea wollastoni. These lived The scale bar is 5 cm – it’s one big oyster! We are advertising some great science jobs. This is a great opportunity if you are interested in science or a career in science – get some hands on experience. It could be the highlight of your ! This lovely fossil is of a million year old Miocene dicotyledon leaf from Cromwell.
Its margin and veins are perfectly preserved and you can even spot some insect damage. Fossil leaves hold information on past climates and are often used in paleoenvironmental studies. And a great explanation of preliminary findings. We had samples from over sites returned to us – a lot of grass as samples were collected over 12 weeks.
This is starting to provide interesting data quantifying the impact of our normal day to day activities on fossil fuel produced CO2 in the environment. We want more samples and are kicking off another round of sampling from today.

Tritium and Water Dating Laboratory · Sending samples · Introduction Introduction to Water Dating and Tracer Analysis. GNS provides a number of complementary age tracer methods to date water samples. These include tritium, CFCs, SF6.
A New Zealand laboratory has come first of 70 laboratories around the world in water dating. The GNS Science tritium and water dating laboratory in Lower Hutt was four times more accurate than the second-placed laboratory in the international comparison run by International Atomic Energy Agency. Each laboratory was asked to measure tritium concentrations in six blind water samples.
GNS Science was the only one to get all six right. Laboratory manager Uwe Morgenstern said the result was gratifying. GNS’s tritium measurements have been adopted by the New Zealand government as a benchmark for the security of drinking water from aquifers, as water age indicates if groundwater is free of pathogens. Measuring water age also helps with the management of nitrification of lakes such as Rotorua and Taupo.

Our innovative, cutting edge techniques give by a large margin the highest accuracy and precision in tritium analysis . This high tritium precision allows for new understanding of processes in groundwater, oceans, and glaciers, such as. Our tracer data are used to understand and manage groundwater resources, and to understand how groundwater dynamics change over time. We welcome collaborative research and the opportunity to contribute or assist in research design.
