Work by Stephanie Wright from the University of Exeter found that
if ocean sediments are heavily contaminated with microplastics, marine lugworms eat less and their energy levels suffer.
Not exact matches
If there is — say some combination of other elements adding to produce a better structure for the «cage» of water molecules that trap methane, say occurring naturally in pore spaces in
sediment or leaf litter washed into the
ocean — it ought to be discoverabe.
For example
if the deep
oceans starts to become more acidic, some carbonate will be dissolved from
sediments.
Best guess — mostly into the
ocean;
if we're lucky as sinking dead plankton directly into
sediments;
if we're not lucky, as increasing acidity, slime and toxic algae blooms.
If exposure to a more acidic pH caused a decline in some sea urchin populations, how might this affect the storage of carbon in
ocean sediments?
If a crack opens up in the
ocean floor down to clathrate deposits, the pressure on these deposits is reduced since the density of the
sediment that formerly kept the pressure at a certain level is 2.5 times as much as the water which fills the crack.
It is calculated that
if the decline in CO2 levels were to continue at the same rate as it has over the past 140 million years, life on Earth would begin to die as soon as two million years from now and would slowly perish almost entirely as carbon continued to be lost to the deep
ocean sediments.
