Ice core aquisition and analysis

State-of-the-art capability

BAS provides the UK’s only capability to recover and analyse ice cores (up to 1000 m).  We provide ice core drills for deployment by research teams around the world, and operate state-of-the-art laboratories in Cambridge to provide a wide range of climatologically and environmentally-relevant chemical, gas and stable isotope analyses.

Expertise

Ice cores from Antarctica, the Arctic and mi-latitude locations are drilled, processed and analysed by BAS scientists and engineers. Laboratory facilities in Cambridge allow the analysis and interpretation of ice cores dating from hundreds to hundreds of thousands of years old. The current facilities allow ice to be stored, processed, and analysed, using a number of analytical chemistry, isotopic and gas extraction techniques to provide information from the past to help to predict the future.

Ice chemistry laboratories

The interpretation of ice core records including climate and atmospheric modelling studies, aimed both at improving ice core proxies, and understanding the couplings and interactions between different parts of the earth-system.

A bespoke Continuous Flow Analysis (CFA) method coupled to a suite of instruments and detectors including:

• Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
  • Elemental chemistry
• Fast Ion Chromatography (FIC)
  • Major ion chemistry
• Fluorescence detectors
  • Hydrogen peroxide, ammonium, calcium, nitrate
• Gas analysers (Picarro and Zara)
  • Continuous methane and carbon monoxide
