I've done my best work when I've let myself get lost in a deep hole of words,
returning to the surface for air unsure of how long I've been under.
Work has also been hampered because researchers must
return to the surface for fresh air every three hours — the cave contains high levels of carbon dioxide.
A large fraction of the injected water
returns to the surface as wastewater containing high concentrations of heavy metals, oils, greases and soluble organic compounds [161].
One incident that is emblematic of the problems occurred on 8 March, a month before the accident, when BP discovered that drilling fluid had leaked into rocks 5000 metres below the sea floor instead of
returning to the surface via a pipe.
The water is heated through contact with the rock and is
then returned to the surface through a second borehole where it is used to generate electricity.
Observations show when water vapour is taken up by the atmosphere through evaporation, the updraughts can either rise to 15 km to form clouds that produce heavy rains or rise just a few kilometres
before returning to the surface without forming rain clouds.
Although a small but possibly significant percentage of the sinking organic material becomes buried in the ocean sediment, most of the dissolved carbon dioxide is
eventually returned to the surface via ocean currents - but this can take centuries or millennia.
They explore its relationship with that which remains outside the frame, with an exterior
which return to the surface as absolute otherness, a non-assimilable sign.
In fact it was only because she'd been away from the atmosphere for so long that she was appalled,
on returning to the surface, by how much the climate had changed during her absence — a shock that sparked her passionate interest in the political race to save humanity's breathable commons.
What's more, when the
minerals return to the surface in the forearcs of subduction zones, they can break down over millions of years, releasing gases back to atmosphere once again.
Some of these patients improved after they received hyperbaric oxygen therapy, the same type of treatment used for scuba divers
who return to the surface of the water too quickly and get the bends.
The historic balloon flight, which was inspired by the visionary Jules Verne's book Journey to the Centre of the Earth, lasted about 25 minutes, from its departure to the landing at the bottom of the Mamet cave and
successful return to the surface.
When you've
finally returned to the surface, all of the fish you've caught along the way are flung high into the air, and you begin shooting them out of the sky, collecting their cash value as they explode.
The desperate survivors who cling to existence beneath the ruins of post-apocalyptic Moscow have long given up hope of
life returning to the surface... except for one.
The resulting photographs subvert the disembodied experience of watching a screen, and
ultimately return us to its surface as an unlikely point of contact and physical orientation.
I'm basically in agreement with Dr. Archer's assessment, although I think the greatest complication in his long - term view is whether we saturate the ocean to the point that when surface waters from the fossil
era return to the surface some thousand years from now, they become a source, or will they still be a sink.
During offshore fracking, a significant amount of fracking
fluid returns to the surface and is either discharged into the ocean or transported for onshore ground injection.
Water
now returning to the surface having entered deep ocean during the MWP may be inducing release of oceanic CO2 in response to altered pH, and this release could be expected to provide the steady increase in atmospheric CO2 concentration (of at least 1.5 ppm / year) that is observed to be independent of temperature variations.
When kinetic energy is converted to potential energy by the interaction with gravity whilst air is rising that disappears from the planet's radiative exchange with sun and space until it is
returned to the surface again by descending air.
