Yan suspected this wandering could shift the distribution of
ocean mass enough to brake Earth's spinning, thus slightly stretching day length.

A study says there is
enough ocean to grow 100 times the fish we eat, but
mass fish farming is not the simple solution it seems, says Olive Heffernan
When it's cold
enough to form ice shelves that extend over the Antarctic land
mass and into the
ocean, much of what drops to the seafloor is sand and gravel that the glacier has picked up on its slow march from the continent's ice cap.
This new map allows scientists to determine the age of large swaths of the second largest
mass of ice on Earth, an area containing
enough water to raise
ocean levels by about 20 feet.
«Starting back in the 1960s, for various reasons people claimed there was very little continental
mass, and so there wasn't
enough weathering to affect the chemistry of the
ocean.
There are only a dozen known asteroids and dwarf planets with
enough mass to boil the
oceans (2x10 ^ 18 kg), these include (Vesta 2x10 ^ 20 kg) and Pluto (10 ^ 22 kg), however none of these objects will intersect Earth's orbit and pose a threat to tardigrades.
It seems to me that they must show deeper mixing than 50 M, since there is not
enough mass in the upper 50 meters of
ocean to account for the annual heat storage changes that are implied by observations for the the full integrated 700 meter volume of
ocean.
The
mass balance and d13C balance shows that vegetation as sink is not large
enough to absorb all human CO2 if the
oceans are a source and ice cores show that CO2 and temperature go to a (surprisingly linear) new equilibrium for every change in temperature level, not a sustained increase or decrease.
Interestingly
enough, if you correct that first graph in this post for seasonal effects (you know, plants growing in the spring, dying off in the fall), and the fact that about half (by
mass balance) of our emissions are absorbed by
ocean and plant sinks, those two lines will track each other very well.
If it's going into
ocean heating (
ocean heat content), that is
enough mass that it might take a while to actually reach an equilibrium value.
The former redistributes
ocean volume within the basins, while the latter alters Earth's gravitational field and rate of rotation
enough to change the distribution of
ocean mass around the surface of the Earth.
During these events, the anoxic
oceans outgassed
enough toxic hydrogen sulfide to cause varying sizes of
mass extinctions of marine and terrestrial life.
