@vicgrinberg a number of years ago, I used this photograph in a presentation I gave at a conference in Krakow. I was discussing the mixture of hydrocarbons in the unresolved complex mixture often seen in petroleum and environmental samples (see https://en.wikipedia.org/wiki/Unresolved_complex_mixture). It caused a bit of amusement...

And the final session of #BOGS2024 completes with two presentations
Robert Sparkes - "Total" Organic Carbon
Wanyue Zhao - Monitoring uptake of root-derived carbon into the soil carbon pool and microbial community using stable isotope probing of vola􀆟le organic compounds (SIPVOC) and SIP-PLFA analysis

#OrganicGeochemistry #BioGeoChemistry #biomarker #ChemicalFossil

We move to the final session of #BOGS2024 with five presentations, the first three being
Kirsi Keskitalo - Composition of organic carbon in the flocculation layer on the Laptev, East Siberian, and Kara seas
Bridget Warren - A terrestrial early Eocene environment from the Rockall Trough
Zoë van Kemenade - A reconstruction of Neogene atmospheric carbon dioxide across globally distributed marine sites using a multi-biomarker approach

#OrganicGeochemistry #BioGeoChemistry #biomarker #ChemicalFossil

Session six of #BOGS2024 continues with
Joe Hingley - Evaluating grain size controls on lipid biomarker distributions in marine sediments
Florence Dennis Uzuh - Assessing the Removal Efficiency of Methyl Orange using a Novel Nyex RosaloxTM Process Flow Through Cell
Cedric Andreasen - Applying amide bound 3-hydroxy decanoic acid as a biomarker for sewage fungus (Sphaerotilus natans)
