They want to ask questions that cross scientific boundaries, such as how
does ocean chemistry affect biology or how does the geology on the seafloor affect the physics of flowing water.
Does ocean chemistry alter climate?
Not exact matches
As atmospheric CO2 levels rise, those in the
oceans do too, changing the
chemistry of the seawater.
Alter the
ocean chemistry just a bit, however, and a greater proportion of the shells
do not develop normally.
The first thing Langdon set out to
do was balance the
chemistry of Biosphere's
ocean.
If Europa
does have an
ocean, the academy report recommends a series of satellite missions and lab simulations of the
chemistry at the boundary between Europa's
ocean and its rocky core.
Yet because ship emissions are not intended to alter
ocean chemistry, they
do not violate the moratorium, says Jim Thomas of the ETC Group, a think tank that consults for the CBD.
AB: Since many astrobiologists are currently examining hydrothermal vents, in search of extremophiles,
does the prebiotic
chemistry actually get decomposed rather than enhanced by the presence of such
ocean venting?
This setup consists of an atmospheric model with a simple mixed - layer
ocean model, but that doesn't include
chemistry, aerosol vegetation or dynamic ice sheet modules.
What
do you KNOW about physics,
chemistry and biology of
Oceans?
The
ocean model I used
does carbon
chemistry, with plankton and gas exchange and all that.
Experiments on echinoderms, for example, show great sensitivity of reproductive success on
ocean chemistry changes but we
do not know the potential for micro-evolutionary adaptation.
We
do not know what changing
ocean chemistry will
do to marine biota (other than some calcifiers) and especially we
do not know what the long - term chronic effects will be on ecosystems.
«Basic
chemistry tells us that within decades there may be serious trouble brewing in the polar
oceans,» says James Orr, lead author and
ocean modeler from the French Laboratoire des Sciences
du Climat et de l'Environnement, who further adds, «unlike climate predictions, the uncertainties here are small.»
There is no surprise that the CO2 in the atmosphere winds up partially in the
oceans, nor that the amount of CO2 going into or coming out of the
oceans varies in time and space — that's simple equilibrium
chemistry between the liquid (that is, dissolved) and gaseous phases, and
does explain part of the variability about the long term rising trend.
I
do certainly agree that
ocean chemistry and pH is not only about CO2 but very much about buffering where carbonate supply is essential.
Because the calculations to exactly balance that reaction can be complicated, given temperature and salinity considerations, which is a bit much to expect the
ocean to
do in its head without a calculator or formal education in
chemistry.
I looked into this after your post about a year ago on the Argo float temperatures and how the
ocean generally
does not heat above 30 degrees C. My knowledge of
chemistry is limited; but, I noted these things: Carbon dioxide as well as other gasses in water act like a liquid.
If you wanted to
do that any scale that would be meaningful to global coral health or to
ocean chemistry, the unanticipated consequences of large actions like that, that are, you know, it's such a complicated system — become very hard to model.
And talk about the invisible things that we're
doing, that shift in the
chemistry of the
oceans is completely invisible but very consequential in the long run.
Carbonic acid is altering the
chemistry of the
ocean, making it difficult for some plants and animals to live how they live and
do what they
do.
It didn't get a lot of discussion before it closed; this area includes the unexpected feedbacks for which we have known good science —
ocean chemistry.
