The ultimate trajectory of the global ocean relies entirely on the rapid cessation of anthropogenic carbon emissions, before the acidic tide outpaces the evolutionary resilience of the marine world entirely.
We must become better stewards of this planet, because the ecological systems we protect are the very ones that sustain us.

It is a uniquely humbling experience to realize that the microscopic apex predators of epochs past are merely sleeping beneath the ice, wholly indifferent to the passage of human history.

uranium powered bacteria? :-P

`Microbial community analysis reveals enrichment of fermentative and sulphate-reducing taxa, consistent with redox conditions favouring U reduction. By demonstrating the stability of immobilised U(V) alongside U(IV), this work advances the understanding of uranium biogeochemistry and offers new insights for sustainable remediation strategies.`

The final three of seven poster presentations at #BOGS2026 are:
Does recent seagrass expansion increase carbon storage in an atoll environment?
Advancements in amino-acid hydroxyproline radiocarbon dating: post-LC cleanup protocols
Evaluating Orbitrap HRAM-MS for stable isotope incorporation analysis

I'm sorry to have missed the Meeting this year but I hope to attend #BOGS2027, wherever it is... updates to follow!
