ACRA Webinar on Bones: Isotopes in Dating, Diets and Migration Studies
Bones: Isotopes in Dating, Diets and Migration Studies
Live Webinar: April 14, 2022 – 2:00 PM to 3:30 PM Eastern Time
A highlight on tsunami research: Professor Sam Purkis
A study researchering the dynamics of carbonate stratigraphy and vulnerability of sea life to climate change used a combination of radiocarbon and U-Th dating of corals and cemented sediments to date an incipient submarine landslide
Tracing Volcanic Eruptions using Strontium Isotopes
Volcanic eruptions are significant geological events with far reaching implications. The analysis of isotopes in various sample types can provide information on the timing and magnitude of past volcanic eruptions.
Lead Isotopes in Archaeology
In archaeological studies, lead isotopes are measured for two main applications: tracing origin of metal artefacts and reconstructing human origin and migratory patterns.
Boron Isotopes as a Tracer for Oceanic CO2 and Ocean Acidification
Boron isotopes are predominately made up of two naturally occurring stable isotopes – 10B and 11B. In the biosphere, boron represents a trace element integrated into organisms, allowing one to reconstruct variability in δ11B over time.
Strontium Isotopes (87Sr/86Sr) for Geochronology
Strontium ratios have varied in the world’s oceans through time as a result of fluctuations in strontium type and availability, often resulting from weathering of continental materials as well as volcanic activity at the mid-oceanic ridge. Such variations are recorded in oceanic sediment as a result of the precipitation of minerals from seawater, which has been used as a basis for the 87Sr/86Sr marine curve.
Corals: A marine recorder of climate variability
Before a time series of climate variability can be developed, the coral growth bands must first be dated. Corals can be dated using radiocarbon dating, U-Th dating and/or Sr-Sr dating.
Sediments Webinar: Dating & Environmental Reconstructions
Isobar Science and Beta Analytic’s webinar on sediments focuses on dating & environmental reconstructions. This complimentary webinar takes place on December 2, 2021 at 12:00 PM Eastern Time (US and Canada).
