Ice core records are an important foundational archive for paleoclimatology. Through them scientists have reconstructed high resolution atmospheric CO2 and temperature records covering hundreds of thousands of years.
Bones and teeth are relatively common within the archaeological and paleontological record due to the tendency for high preservation after burial.
Isobar Science is now offering a Strontium Chronology Service for dating marine carbonate samples. Strontium Isotope Ratios (87Sr/86Sr) within the ocean have varied through time, creating a predictable seawater curve that can be used for dating calibration.
Bones and teeth can be used for a variety of different isotopic analyses, including Oxygen, Strontium, Lead, Neodymium, Carbon, Nitrogen and dating (radiocarbon and in some cases Uranium-Thorium). There are important requirements for bone samples to ensure they produce accurate results.
Isobar’s webinar will focus on boron and strontium to identify isotopic variability in the hydrosphere, including identification of pollution sources.
Caves are natural intact cavities found in many different landscapes which have been accessible to humans and animals for millions of years.
Biogenic apatite is a molecule made up of calcium, phosphorus and oxygen. Importantly, the phosphorus is found primarily in the form of phosphate (PO4) – which is present in both soft and hard tissues in organisms.
There are numerous different options for dating marine samples, each with applicable timespans, levels of certainty and limitations.
