Methods

To obtain multiproxy records, this working group applies a multidisciplinary approach of e.g. geocryological, geochronological, sedimentological, hydrochemical, isotope geochemical and remote sensing methods.

Sedimentology

• Granulometry
• Biogeochemistry (C, N, S), lipid biomarkers (with cooperation partners)
• heavy mineral spectra
• ice content
• mass specific magnetic susceptibility

Cryolithology

• Cryofacies analysis

Geochronology (with partners)

• Radiocarbon
• Optically Stimulated Luminescence Dating
• ³⁶Cl/Cl
• ²³⁰Th/²³⁴U

Paleoecology (with cooperation partners)

• pollen
• plant macro fossils
• ostracods
• diatoms
• chironomids
• testacea
• mammut fauna remnants

Remote Sensing and GIS

• with the virtual working group „REmote Sensing of Polar Non-glaciated and Sensitive Environments“

Stable Isotopes (with the AWI Working Group „Stable-Isotope Geochemistry“)

• ² H (D)
• ¹⁸O
• ¹³C
