Boron Isotopes

Boron & Nitrates Webinar: Tracing Sources of Anthropogenic Pollution

Beta Analytic and Isobar Science invite all researchers to view our complimentary webinar focusing on Boron & Nitrates: Tracing Sources of Anthropogenic Pollution

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.

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.

Geochemistry: Stable and Radioactive Isotopes

In geochemical research, stable and unstable isotopes are used to understand the chemistry behind natural processes. Isotopes are different forms of a single element, with differing numbers of neutrons within their nucleus, resulting in different atomic masses.

Analysing Water Samples

Stable and radioactive isotopes can be analysed in groundwater and surface water samples in order to assess the magnitude and origin of pollution, rate of pollution infiltration into the environment, and timing of water interactions with the atmosphere.

Shells, corals and other carbonates

Shells, corals and other carbonates are widely used in order to assess variability in climate and environmental conditions in time. A variety of stable and radioactive isotopes can be used to date these samples and provide further information on environmental context during their lifespan.

Studying past climates using stable isotopes

The study of past climates (paleoclimatology) offers an opportunity to improve the predictability of future climate change. The stable isotopes of boron (δ11B) and oxygen (δ18O) are two important variables used to reconstruct climate in a variety of natural archives.
