How ocean drilling programs recover continuous climate records spanning millions of years.
How the ratio of oxygen-18 to oxygen-16 in fossil shells reveals past climate conditions.
How coccolithophores influence the global carbon cycle through calcification and photosynthesis.
Exploring the intricate siliceous skeletons of radiolarians and their role in paleoceanography.
Global Marine Fossil Lab is a collaborative network of scientists studying microscopic fossils preserved in ocean sediments. Our work focuses on foraminifera, diatoms, radiolarians, and coccolithophores — organisms whose calcium carbonate and silica shells accumulate on the seafloor, creating a detailed archive of past ocean conditions.
By combining traditional micropaleontological techniques with modern geochemical analysis, we reconstruct sea surface temperatures, deep-water circulation patterns, and atmospheric CO₂ concentrations spanning millions of years of Earth history.
