Slippery stretching explains ocean floor formation
For the first time, scientists have found regions of the earth's crust which are stretching apart to form new sea floor; their findings are published in Nature today (July 27). Most new ocean floor is made when undersea volcanic activity splits the crust and molten rock fills the gaps. However some new ocean floor develops when rock stretches along gently inclined tectonic faults called detachment faults. (2006-07-27)

Seabed Silt In Indian Ocean Consists Of Remains Of Summer Plankton
Almost 90% of the silt on the floor of the Indian Ocean consists of the remains of blooming plankton during the summer monsoon.

How the Earth's Pacific plates collapsed
Scientists drilling into the ocean floor have for the first time found out what happens when one tectonic plate first gets pushed under another.

The very hungry sea anemone
The surprising culinary preferences of an abyssal sea anemone have been unveiled by a team of scientists from the National Oceanography Centre. New time-lapse photography of the abyssal sea floor shows that this type of anemone can eat animals up to six times its weight and moves around the ocean floor by burrowing. The lead author of this study, Jennifer Durden, a Ph.D. student at the NOC, explained that these heavy meals can take the anemone up to 80 hours to digest. (2015-07-02)

Do animals control earth's oxygen level?
For the first time, researchers have measured how the production of algae and the Earth's oxygen level affect each other -- what you might call 'Earth's heartbeat'. Studies of 540 million-year-old limestone indicate that it is not just the oxygen level that affects animals, but that animals can indeed regulate the oxygen level. (2019-09-10)
