Her results so far suggest that lower pH leads to declines in fertilization, inlarval development, and also in settlement - the stage at which the coral larvae drop out of the water column,attach themselves to something solid, and start producing new colonies.
not only are they unable to survive in acidic water, they are also unable to reproduce
So far CO2 emissions havereduced the pH there by about 0.1
a scientific explanation for why these changes are not small
For life on land this process is a boon; every ton OfCO2 the oceans remove from the atmosphere is a ton that's notcontributing to global warming. But for life in the sea the picture looks different. The head of the National Oceanicand Atmospheric Administration, Jane Lubchenco, a marine ecologist, has called ocean acidification globalwarming's "equally evil twin."
the ocean's are dying trying to keep the earth cool. what happens to the oceans if we dont change? what happens to earth once the oceans are destroyed?
In the 1990san international team of scientists undertook a massive research project that involved collecting and analyzingmore than 77,000 seawater samples from different depths and locations around the world.
an international research project spanning 15 years revealed that oceans have absorbed 30% of human generated CO2 in the last 200 years and now absorb a million tons of CO2 per hr
he sea around Castello Aragonese provides a window onto the oceans of 2050 andbeyond
The CO2 from volcanic vents creates carbonic acid, which can turn seawater corrosive in large quantities. In Castello Arogonese, these levels have risen to a point matching the anticipated levels of world oceans in 2050-2100 and is thusly being used for scientists to study the effects the oceanic environment will face in the future.
Barnacles are really tough," Hall-Spencer observed. In the areas where the water was most acidified, though, they were missing.
some of the most resilient forms of life are struggling to survive in the CA Island coastline.
