- phys.org Shape and depth of ocean floor profoundly influence how carbon is stored there, study shows
The movement of carbon between the atmosphere, oceans and continents—the carbon cycle—is a fundamental process that regulates Earth's climate. Some factors, like volcanic eruptions or human activity, emit carbon dioxide into the atmosphere. Others, such as forests and oceans, absorb that CO2. In a w...
The work is published in the journal Proceedings of the National Academy of Sciences.
"We were able to show, for the first time, that the shape and depth of the ocean floor play major roles in the long-term carbon cycle," said Matthew Bogumil, ...
The long-term carbon cycle has a lot of moving parts, all functioning on different time scales. One of those parts is seafloor bathymetry—the mean depth and shape of the ocean floor. This is, in turn, controlled by the relative positions of the continent and the oceans, sea level, as well as the flow within Earth's mantle. Carbon cycle models calibrated with paleoclimate datasets form the basis for scientists' understanding of the global marine carbon cycle and how it responds to natural perturbations.
"Typically, carbon cycle models over Earth's history consider seafloor bathymetry as either a fixed or a secondary factor," said Tushar Mittal, the paper's co-author and a professor of geosciences at Pennsylvania State University.

Environmental activists sue Norway over seabed mineral plan
Norway's parliament in January approved a proposal to open a vast ocean area larger than Britain for seabed mineral exploration after a government-commissioned study concluded that its impact would be minimal.
Deep-sea mining critics say industrial activity could destroy yet-to-be discovered species that live at the depths of some 1,500-3,000 metres (5,000-10,000 feet) and more, where seabed mineral deposits are located.

Electrified reefs and offshore aquaculture tidalpunk combos for at risk and indigent fisher communities?
I’ve been thinking of how to combine electrified reefs with open ocean aquaculture as a way of helping indigent and at-risk fisher communities to deal with climate change. Of course, there’s no technological solution to social problems, so I still have to consider the social and organizational aspects of using these technologies in indigent fisher communities.
