It's actually the microscopic, fossilized remains of very tiny sea organisms known as diatoms.

Not exact matches

The team analysed the chemical composition of tiny shells built by organisms (foraminifera) that had lived in the water column and at the sea bottom before their shells became embedded in the seafloor sediments.

By comparing the relative abundance of species of tiny organisms preserved in the deep - sea cores, PRISM scientists could roughly map how cold - loving organisms gave way to warm ones (and vice versa) at different times in the past.

A well - known issue with LGM proxies is that the most abundant type of proxy data, using the species composition of tiny marine organisms called foraminifera, probably underestimates sea surface cooling over vast stretches of the tropical oceans; other methods like alkenone and Mg / Ca ratios give colder temperatures (but aren't all coherent either).

The study, published today in the journal Nature, draws on a new record of tropical sea surface temperature dating back to 1500, captured in fossilised corals and tiny marine organisms.

Understanding the biomechanics of this little snail could help engineers design some nifty sea - faring robots, and it could also help with ecological studies: Zooplankton like helicina move upwards to the surface of the ocean each night to eat (and avoid being eaten), and this mass migration of tiny organisms is one of the biggest biomass movements on the planet.

Amoeba - like tiny organisms that live in the sea.

If that finding stood the test of time, it would indeed be momentous; the vast clouds of tiny photosynthesizing organisms in the seas are an important part of the carbon cycle and underpin the marine food chain.

If waters around coral reefs become too acidic, we will no longer see beautiful coral sculptures, but only a slimy coating of tiny organisms on the sea bed.
