Analysing Water Samples
/in Boron Isotopes, Lead Isotopes, news, Sr Isotopes /by Haley GershonStable 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.
Isobar Science 2021 Holiday Schedule
/in Company Updates /by isobarPlease be informed the Miami lab will be closed on the following dates: November 11, November 25-26, and December 23-January 2.
Paleoclimatology Webinar: Isotopes in dating and climate-proxy relationships
/in U-Th Dating, Webinars /by Haley GershonIsobar Science and Beta Analytic’s paleclimatology webinar focuses on the importance of C-14 and U-Th dating in paleoclimatology, and how archives can be used to reconstruct past climate.
Mineral Dust Samples: Analysing Strontium (Sr), Strontium-Neodymium-Hafnium (Sr-Nd-Hf) and Lead (Pb)
/in Lead Isotopes, Sr Isotopes, Sr-Nd-Hf Isotopes /by isobarThe origin and movement of atmospheric dust can be estimated by analysing the geochemistry of dust collected directly from the atmosphere or from the dust layers found within ice cores or lacustrine and ocean sediment cores.
Shells, corals and other carbonates
/in Boron Isotopes, news, Sr Isotopes, U-Th Dating /by isobarShells, 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.
The use of isotopic analysis on bones: dating, environmental analysis & migration
/in Sr Isotopes /by isobarDifferent isotopes on bone samples may be measured, depending on the scope of the research, and which questions the researcher is seeking to answer.
Assumptions for U-Th Dating: Open vs. Closed Systems
/2 Comments/in U-Th Dating /by isobarThe most optimal samples for accurate U-Th dating are those that exist in closed systems, including speleothems and corals. In some cases, bones and lake sediments may also be used, but the state of your samples should be carefully considered prior to planning your analysis and interpreting U-Th dating results.
What is U-Th dating?
/1 Comment/in U-Th Dating /by isobarU-Th dating is an analytical method used to date calcium carbonate (CaCO3) bearing samples, including cave deposits/speleothems, CaCO3 rock, corals, shells and (in some cases) bones.
Isobar’s Webinar: Application of Sr-Nd-Hf-Pb Isotope Systematics in Earth Science
/in Sr-Nd-Hf Isotopes, Webinars /by isobarView our on-demand webinar “Geochemical Fingerprinting: Application of Sr-Nd-Hf-Pb Isotope Systematics in Earth Science.” Topics include: how different processes control the distribution of elements in the earth system; measuring Sr, Nd, Hf, and Pb and reporting conventions; application of Sr-Nd-Hf-Pb systematics in studying the governing processes in the earth system; research design and sampling strategies; and what to expect from your lab when measuring Sr-Nd-Hf-Pb isotopes.
Strontium, Neodymium, Hafnium, and Lead Isotope Systematics in Earth Science
/in Sr-Nd-Hf Isotopes /by isobarSr, Nd, Hf and Pb are four isotopes that are inherent in many geological settings, and thus have been used to trace the evolution of metamorphic and igneous rocks, track the origin of sediments and dust, analyze weathering regimes and reconstruct past ocean circulation.
Sr-Nd Isotopes for Weathering Studies
/in Sr Isotopes, Sr-Nd-Hf Isotopes /by isobarContinental weathering is an important part of the global carbon cycle. The measurements of strontium and neodymium isotopes have been especially important in this research domain.
Studying past climates using stable isotopes
/in Boron Isotopes /by isobarThe 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.
Isotopic analysis in forensic geography
/in Lead Isotopes, Sr Isotopes /by isobarUsing isotopic analysis of skeletal remains and forensic evidence, one can reconstruct human profiles, analyse the environmental conditions antemortem and estimate the time of death. Other forensics-related investigations using isotope geochemistry include the analysis of trace evidence materials as well as provenancing illegal wildlife, bullets, narcotics, and other forensic evidence.
Tracing the diet of herbivores and omnivores through isotopic analysis
/1 Comment/in Sr Isotopes /by isobarUnderstanding the movement of herbivores across a landscape and ecological dynamics through time is important for current conservation and ecosystem management, while providing valuable insights into evolution and adaptation. Documented historical evidence in the relationship between organisms and their surrounding vegetation is generally limited and thus isotopic analysis of fossils can provide valuable insights into this important area of research.

U-Th Dating vs Radiocarbon Dating
/in U-Th Dating /by isobarThe analysis of the uranium-thorium (U-Th) decay chain can be used to date a variety of calcium carbonate (CaCO3) bearing samples, including cave deposits (e.g. speleothems), calcium carbonate rock, corals, shells and (in some cases) bones. This method can be used to date samples existing from present day until 500,000 calendar years before present.
