Understanding Ocean Acidification
Welcome to Section 2!
In order to properly appreciate how ocean acidification affects marine life and
coral bleaching, one must be aware of the basic origins and consequences of
this environmental problem. The gradual loss of seawater's pH equilibrium,
known as ocean acidification, is mostly caused by carbon dioxide entering the
ocean from the atmosphere.
An environment becomes
more acidic as a result of the ocean absorbing more carbon dioxide as carbon
dioxide levels rise. Understanding this process is essential because it affects
the chemical equilibrium of seawater, which has significant effects on marine
life and ecosystems as a whole.
Causes
of Ocean Acidification
Carbon dioxide
emissions from human activity are the main cause of ocean acidification. The
amount of carbon dioxide emitted into the atmosphere is largely caused by the
burning of fossil fuels for industrial activities, transportation, and energy
production. The ocean then absorbs this extra carbon dioxide, which raises the
acidity levels.
Natural processes like
rock weathering and volcanic activity are additional variables that contribute
to ocean acidification; but, over millions of years, these components have
remained largely steady.
Effects
of Ocean Acidification
Ocean acidification has
several, potentially disastrous repercussions. The development and growth of
many marine creatures are impacted by acidic seawater, endangering the
wellbeing of entire ecosystems. For instance, shellfish and other marine
species may experience weakening and dissolution of their shells in acidic
settings, increasing their vulnerability to predators and other hazards.
Additionally, fish
behavior, survival, and reproduction can all be impacted by ocean
acidification, which can have an effect on entire food chains. Ocean
acidification poses a threat to coral reefs, which are essential for
maintaining marine biodiversity. This might result in coral bleaching and
eventually the destruction of the reefs.
Overall, ocean acidification
has significant negative effects on ecosystems and marine life, and it is yet
unclear how long these effects will last.
The Role of Carbon Dioxide Emissions
The rising levels of
acidity in our seas are a result of a number of factors, including carbon
dioxide emissions. Burning fossil fuels releases a lot of carbon dioxide into
the atmosphere, making it the main source of the gas. The ocean's pH drops and
acidity rises as a result of carbon dioxide dissolving in saltwater and forming
carbonic acid.
This process is
detrimental to marine ecosystems and has far-reaching impacts on the health of
our seas, aggravating the effects of climate change. Since the ocean takes up
around 25% of the carbon dioxide released by human activity, the acidity of our
oceans rises along with carbon dioxide emissions.
The
Interconnectedness of Carbon Dioxide Emissions and Ocean Acidification
The relationship
between ocean acidification and carbon dioxide emissions also demonstrates the
wider effects of human activity on the health of our planet. Ocean
acidification is a result of our continued use of fossil fuels and carbon
dioxide emissions, which also intensifies other consequences of climate change
such rising sea levels, harsher weather, and habitat degradation.

Reducing carbon dioxide emissions is
essential to addressing climate change and lessening the effects of ocean
acidification, according to the Intergovernmental Panel on Climate Change. |
Potential
Solutions and Mitigation Strategies
One of the most
important steps in combating ocean acidification is reducing carbon dioxide
emissions. We can lower our carbon footprint in a number of ways, such as by
implementing sustainable behaviors, boosting energy efficiency, and utilizing
renewable energy sources.
Carbon capture and
storage, which entails removing carbon dioxide emissions from factories or
power plants and burying it underground, is another possible remedy. Even while
this technology is still in the early stages of research, it has the potential
to greatly reduce emissions and lessen the consequences of ocean acidification.
In the end, combating
ocean acidification at its source necessitates a concerted effort to cut carbon
emissions and advance sustainable lifestyles.
Impact on Marine Life
As we've seen, marine
life is seriously threatened by ocean acidification. The growth and development
of species like shellfish, corals, and plankton that depend on calcium
carbonate to construct their skeletons or shells are directly impacted by
acidification. They have a difficult time surviving and procreating since their
shells breakdown in corrosive waters. This may cause further losses in already
fragile populations by having an impact on entire food webs.
Particularly at risk
are shellfish. They have a harder time building their shells as a result of
acidification, which results in thinner, weaker structures that are unable to
withstand environmental forces. This may have detrimental effects on the
survival of shellfish populations and commercial and subsistence fisheries that
depend on them for a living.
Acidification
Effects on Shellfish
Let's examine the
impact of acidity specifically on shellfish in more detail. According to a
study on oyster larvae, their shells expanded more slowly, became smaller, and
became more asymmetrical when exposed to acidic saltwater. The study also
discovered that the larvae's survival rates dramatically dropped, suggesting
that acidification has an impact on these creatures' ability to survive as well
as grow.
According to a
different study, shellfish may be indirectly impacted by acidification due to
changes in their food sources. The growth and diversity of phytoplankton can be
impacted by acidification, which changes the chemistry of the saltwater and
decreases the amount of food available for the shellfish that eat them. This
could worsen the effects of acidification on already vulnerable populations by
causing further decreases.
Coral Bleaching and Ocean Acidification
Diverse ecosystem known
as coral reefs offer vital habitats to a variety of marine species. They are
quite susceptible to environmental stresses, like as ocean acidification,
though.
The phenomena of coral
bleaching, which is brought on by warm water temperatures that force colorful
algae, or zooxanthellae, to expel themselves, is made worse by ocean
acidification. In the absence of these symbionts, corals become pale and
perish.
Seawater's acidity
hinders corals' ability to form and preserve their skeletons, which eventually
jeopardizes coral health and growth. Furthermore, acidification might decrease
the amount of carbonate ions available for shellfish to use in the construction
of their shells, increasing their risk of dying and having unsuccessful
reproduction.

We shall discuss the
importance of coral reefs and the challenges they confront in the context of
ocean acidification in the next section.
Coral reefs are among
the first ecosystems that spring to mind when we think of thriving, diverse
ecosystems. Diverse marine life forms can be found in these underwater
ecosystems, ranging from tiny invertebrates that support the health and
sustainability of the reef to vibrant fish and sea turtles.
Did you know? Coral reefs cover less than 1% of the
ocean floor but support over 25% of all marine life!
The Effects of Ocean Acidification on Coral Reefs
Among the planet's most
valuable and diverse ecosystems, coral reefs support numerous human communities
and serve as vital home for innumerable marine animals. But these fragile and
vital ecosystems are seriously threatened by ocean acidification.
Ocean acidification, as
we covered in the last part, is the result of seawater's pH dropping as a
result of absorbing carbon dioxide from the atmosphere. Coral reefs and the
creatures that live there are severely harmed by this rise in acidity.
Coral bleaching is one
of the most noticeable and direct consequences of ocean acidification on coral
reefs. Corals expelling the algae that resides
within them in response to stressors like high temperatures or pH shifts
causing them to turn white and leaving them vulnerable to disease and death.
However, bleaching is
not the only impact of ocean acidification on coral reefs. Corals become weaker
and less able to withstand environmental stresses when their calcium carbonate
skeletons are unable to be built, which is another effect of increased acidity.
They become increasingly vulnerable as a result to overfishing, pollution, and
storm damage.
Additionally, the coral
reef's broader ecosystem is impacted by ocean acidification. For instance, a
variety of different creatures depend on the habitat and protection that
coral-built calcium carbonate structures provide. These species are in risk as
well because corals are becoming fewer and weaker.
We have now discussed
the important topic of ocean acidification and how it affects marine life, as
well as the connection between acidity and coral bleaching. Our investigation
into the causes, consequences, and possible remedies has led us to realize how
urgent it is to address this urgent environmental issue.
As we now know,
lowering our carbon footprint is essential to lessening the effects of ocean
acidification, as carbon dioxide emissions contribute significantly to this
process. Furthermore, creative conservation strategies, like regulating ocean
water's acidity, can be put into practice to enhance ocean health and protect
delicate species, including corals and shellfish.
To effectively address
this global issue, we need to make a concentrated effort to increase knowledge
about ocean acidification and to foster interdisciplinary collaboration.
