The phrase
"acidification levels" refers to the measurement or evaluation of how acidic a substance or environment has become. It suggests determining the degree to which something has turned or become more acidic.
Full definition
We conclude that near future
ocean acidification levels is not an immediate threat to the early life history stages of Great Barrier Reef corals in the foreseeable future.
She is exposing them to
increased acidification levels, returning them to ambient conditions, and then re-exposing them to higher acidification conditions to see if they have a «memory» of those conditions and are less sensitive to it.
To date, it remains largely unknown how major pH regulatory systems and their energetics are affected by trans ‐ generational exposure to near ‐
future acidification levels.
Secondly, we calculated the proportion of coral species» ranges exposed to «extremely marginal»
ocean acidification levels (i.e., aragonite saturation states < 3 [34]-RRB-, using projections by Cao and Caldeira [35] based on the University of Victoria Earth System Climate Model version 2.8 [36].
The researchers concluded that
the acidification levels produced were too weak to have caused the disappearance of the calcifying organisms.
Conclusion Parental pre ‐ acclimation to
acidification levels that are beyond the pH that is encountered by this population in its natural habitat (e.g. pHT 7.2) negatively affected larval size and development, potentially through reduced energy transfer.
