Sea ice algae could shed light on past and future climate – Futurity: Research News
Researchers have found a molecule in algae follows the ebbs and flows of sea ice. That could let them reconstruct past ice to shed light on climate change.
A previously problematic molecule turns out to be a reliable proxy for reconstructing sea ice, a new study shows.
The research could help understand human-induced climate change happening now.
In the study in Nature Communications, the researchers show that an organic molecule often found in high-latitude ocean sediments, known as tetra-unsaturated alkenone (C37:4), is produced by one or more previously unknown species of ice-dwelling algae. As sea ice concentration ebbs and flows, so do the algae…
