Ocean acidification is a growing threat caused by carbon dioxide absorption from the atmosphere into the ocean. This process lowers the pH of seawater and impacts marine life through reduced shell formation, coral bleaching, and disruption of food chains. Mitigation requires reducing carbon emissions as well as protecting marine habitats to enhance ecosystem resilience against ocean acidification.
The document discusses ocean acidification, which is the ongoing decrease in ocean pH caused by absorbing CO2 from the atmosphere. This absorption has lowered ocean pH by 0.1 units since the pre-industrial period. Ocean acidification affects organisms that rely on calcium carbonate to build shells and skeletons, as acidity decreases availability of carbonate ions. It also impacts metabolism, photosynthesis, nutrient absorption and more. Effects vary by ecosystem but tropical coral reefs, polar regions, and deep sea corals are threatened by slowed growth and structural damage if acidification continues unchecked. Mitigation requires reducing CO2 emissions and improving ocean health.
Ocean acidification is a term used to describe the changes in the chemistry of the Earth’s ocean i.e. ongoing decrease in the pH and increase in acidity caused by the uptake of anthropogenic carbon dioxide from the atmosphere causing major problems for the coral reefs and other organisms.
This is a small presentation on ocean acidification.It is a compilation of all materials(including present information) I collected related to it, any new information beside this or concerning it please comment.
Ocean acidification is caused by the uptake of excess carbon dioxide from the atmosphere by the oceans, which decreases ocean pH and carbonate ion concentration. Since the industrial revolution, ocean surface pH has decreased by 0.11 pH units. This seemingly small change threatens marine organisms that build shells and skeletons from calcium carbonate, as waters are becoming under-saturated. Lower pH also impairs behaviors like predator detection in fish and habitat selection in clownfish. If carbon dioxide emissions continue unchecked, ocean pH could decrease by 150% by 2100, threatening food security and economies that rely on ocean resources. Strengthening monitoring is critical to understand impacts and guide decisions on addressing ocean acidification.

Ocean acidification is caused by carbon dioxide emissions from burning fossil fuels dissolving into the ocean and changing its chemistry. This leads to a decrease in ocean pH and increase in acidity. Impacts include loss of marine diversity and food sources as species that require calcium carbonate to grow, like corals, pteropods, and foraminifera, struggle under more acidic conditions. A case study from the Arctic Ocean found that pH levels have dropped 0.1 units over the past 30 years and are projected to decrease another 0.3 units by 2100 due to continued carbon dioxide emissions warming the oceans and allowing more absorption. Addressing ocean acidification will require reducing carbon dioxide emissions and improving ocean health through marine protected areas and sustainable fishing
This document discusses ocean acidification, which refers to the ongoing decrease in ocean pH and increase in acidity caused by carbon dioxide uptake from the atmosphere. It explains that 30-40% of human-released CO2 dissolves into oceans, altering water chemistry and increasing acidity levels in the oceans by almost 30% since the industrial era. The impacts of ocean acidification include effects on calcification and calcifying organisms, as well as damage to coral reefs and increased coral bleaching. Preventive measures include reducing CO2 emissions, increasing forestation, and iron fertilization.

The document discusses the relationship between climate change and the ocean. It notes that the ocean absorbs over 30% of carbon dioxide emissions, which is causing the ocean to warm and become more acidic. This is negatively impacting ocean ecosystems and species. Species are migrating to new areas as the climate changes, which could create international issues. Addressing climate change will require significant reductions in greenhouse gas emissions globally through policies like the Paris Agreement. Protecting coastal ecosystems like mangroves and seagrasses can also help mitigate climate change by storing carbon.
Marine waste poses a significant threat to marine ecosystems and human health. It disrupts the delicate balance of marine life through entanglement, ingestion, and introduction of pollutants. This pollution contaminates water sources and seafood, exposing humans to toxins. It also damages coral reefs and coastal habitats, causing declines in fish populations, loss of biodiversity, and economic costs. Addressing this problem requires improved waste management, regulation, education, international cooperation, and cleanup efforts to prevent waste from entering oceans and mitigate current impacts.
The document discusses various sources of marine pollution including direct discharge of waste, land runoff, ship pollution, and atmospheric pollution. It describes different types of pollution such as acidification from increased carbon dioxide levels, eutrophication from excess nutrients, plastic debris accumulation in oceans, and toxins that do not break down rapidly. Deep sea mining is also addressed as a potential source of disturbance. The seminar highlights how these various forms of pollution negatively impact marine environments and organisms.
The document discusses the causes and effects of marine pollution. It outlines several major sources of marine pollution including land-based runoff from agriculture and development, shipping activities, disposal of plastic waste, and offshore oil drilling. These pollution sources introduce excess nutrients, sediments, toxic chemicals, and invasive species into oceans. This causes problems like algal blooms, dead zones, entanglement and ingestion of plastic by wildlife, contamination of seafood, and damage to coral reefs. Climate change is also exacerbating issues like ocean acidification that threaten marine ecosystems.
The main threats to coral reefs include coral bleaching from global climate change, diseases affecting corals and other reef organisms, coral-eating crown-of-thorns starfish and other predators, invasive species, overfishing, engineering practices that damage reefs such as port construction, coral mining, and destruction from other construction activities. These threats stress and damage corals, reducing coral cover and biodiversity and degrading vital reef ecosystems.
Climate change is affecting natural food levels in oceans and seas in several ways:
1) Rising water temperatures and ocean acidification are damaging coral reefs and reducing habitats for fish and other marine life.
2) Changes in rainfall patterns and melting ice are altering freshwater flows into oceans, affecting food sources and habitats.
3) Increased frequency of extreme weather events like hurricanes are causing disruption to marine ecosystems.
Coral reef Threats, conservation and Restoration.pptxVIRENDRA KUMAR
Coral reefs are some of the most diverse ecosystems in the world. About 25% of the ocean's fish depend on healthy coral reefs. Unfortunately, coral reef ecosystems are severely threatened. Some threats are natural, such as diseases, predators, and storms. Other threats are caused by people, including pollution, sedimentation, unsustainable fishing practices, and climate change, which is raising ocean temperatures and causing ocean acidification. Saving and restoring the world's coral reefs requires a multi-pronged approach that ranges from the local to the global level.
The document discusses various topics related to oceans and sea pollution including:
1) It provides background on the importance of oceans and water to life on Earth. Approximately 71% of the planet is covered by oceans which provide habitat for many species and play a key role in regulating climate.
2) It discusses two types of sea pollution - direct and indirect. Direct pollution involves toxic waste being dumped directly into oceans while indirect results from land-based pollution eventually making its way into waterways.
3) Other threats to oceans mentioned include overfishing, exploration of non-renewable resources like sand and coral reefs, and dumping of plastic waste which can harm sea life.
4) The conclusion emphasizes that

Seagrasses act as important carbon sinks, trapping carbon for thousands of years and reducing the impacts of climate change and ocean acidification. They photosynthesize, removing carbon dioxide from water and oceans. However, seagrass meadows are declining globally at a rate four times faster than rainforests. While terrestrial forests receive more attention as carbon sinks, seagrasses also store large amounts of "blue carbon" and provide valuable ecosystem services. There is a need to increase awareness of seagrasses and protect these threatened coastal habitats.
One of the six lectures composing 'Exploring Ocean, Explore the Planet Earth' online course offered by Blue Green Foundation Bangladesh & Octophin. The training was attended by participants from 40 countries. The presentation is organized in three sections: (i) the good- describing what benefits we get from the Ocean, (ii) the bad- bad things happening to the ocean because of human activities, e.g. climate change and their impacts on the sea, (iii) the ugly- very bad things that are happening to the sea due to anthropogenic activities, pollution and their impacts on ocean life forms are discussed in this section.
This document discusses marine plastic pollution. It begins by noting that oceans cover 71% of the Earth's surface and play an important role in the planet's chemical and biological balance, but that human activity has degraded ocean habitats and caused mass deaths of marine life. It then defines marine pollution and lists various pollutants like sewage, pesticides, plastic waste, and oil as well as their sources and effects. The document concludes by emphasizing the importance of oceans for food and ecosystems and the need to prevent pollution and protect marine environments.
This document summarizes a student's research project on genetic regulation of carbon sequestration by molluscs. The student analyzed how oysters are able to adapt and survive in acidified waters caused by ocean acidification. Several studies were reviewed showing oysters have genes that allow them to withstand stresses like heat, oxidation and apoptosis. While oyster larvae are initially affected, they can still metabolize, feed and develop normally even in acidified conditions. The student concluded oysters can survive in high CO2 waters through adaptive genes despite some effects early in development and reproduction.
The document provides an overview of the threats facing biodiversity in the Great Barrier Reef due to factors like climate change, pollution, overfishing, and natural disasters. It discusses the endangered species in the reef and the causes of their endangerment. Solutions discussed include the Great Barrier Reef Marine Park Authority's management plans, Outlook Report, Biodiversity Strategy, and Reef Water Protection Plan, which aim to protect species and their habitats in the reef.
The Great Barrier Reef is the largest coral reef system in the world, located off the coast of Australia. It is home to thousands of plant and animal species but is endangered due to threats like climate change, pollution, overfishing, and natural disasters. Conservation efforts include the Great Barrier Reef Marine Park Authority, which manages the reef, and plans like the Reef Water Protection Plan and Biodiversity Strategy that aim to protect water quality and preserve species diversity in the reef.
1. The document discusses ocean pollution and deoxygenation of oceans. It notes that over 50% of Earth's oxygen is produced by plankton in oceans and deoxygenation is caused by chemical runoff and global warming.
2. Mangrove trees and whales help mitigate climate change through carbon absorption and storage. Mangrove trees absorb 10 times more carbon than forests. Whales store carbon in their bodies.

2. Introduction
Introduction
Ocean acidification is a silent threat
that is rapidly impacting our marine
ecosystems. It occurs when carbon
dioxide is absorbed by seawater,
resulting in a decrease in pH. This
process has detrimental effects on
marine life, including coral bleaching,
reduced shell formation, and disruption
of food chains. Understanding the
causes and consequences of ocean
acidification is crucial for developing
strategies to mitigate its effects.

causes and consequences of ocean
acidification is crucial for developing
strategies to mitigate its effects.
3. Carbon Dioxide Absorption
Carbon Dioxide Absorption
Ocean acidification is primarily caused by
the absorption of carbon dioxide from the
atmosphere into seawater. Increased
carbon dioxide emissions from human
activities, such as burning fossil fuels and
deforestation, have led to a significant rise
in atmospheric CO2 levels. This excess CO2
is then dissolved into the ocean, triggering
a series of chemical reactions that result in
the acidification of seawater.

is then dissolved into the ocean, triggering
a series of chemical reactions that result in
the acidification of seawater.
4. pH Levels and Acidification
pH Levels and Acidification
pH is a measure of acidity or alkalinity
in a solution. The pH scale ranges
from to 14, with 7 being neutral. As
carbon dioxide dissolves in seawater,
it forms carbonic acid, which lowers
the pH. Over the past two centuries,
the average pH of the ocean has
decreased by approximately .1 units,
representing a 30% increase in
acidity. This rapid acidification poses
a significant threat to marine
organisms and ecosystems.

organisms and ecosystems.
5. Impact on Coral Reefs
Impact on Coral Reefs
Coral reefs are particularly vulnerable
to ocean acidification. The decreased
pH inhibits the ability of corals to build
and maintain their calcium carbonate
skeletons, leading to coral bleaching.
Without the structural support of
healthy coral reefs, entire ecosystems
suffer, as many marine species rely on
reefs for food and habitat.
Additionally, the loss of coral reefs
reduces coastal protection from
storms and erosion.

Additionally, the loss of coral reefs
reduces coastal protection from
storms and erosion.
6. Shell Formation Disruption
Shell Formation Disruption
Ocean acidification also affects marine
organisms that rely on calcium carbonate for
shell formation, such as mollusks,
crustaceans, and some plankton. The
increased acidity makes it challenging for
these organisms to extract the necessary
carbonate ions from seawater, resulting in
weakened or deformed shells. This can have
cascading effects on the entire food web, as
many species depend on these shell-forming
organisms as a primary food source.

7. Disruption of Marine Food Chains
Disruption of Marine Food Chains
Ocean acidification disrupts the
intricate balance of marine food
chains. The reduced availability of
carbonate ions affects the growth and
survival of calcifying organisms, which
are essential prey for many fish and
marine mammals. As these prey
populations decline, predators higher
up the food chain face food scarcity
and potential population decline. This
disruption can have far-reaching
consequences for both commercial
and subsistence fisheries.

Mitigation Strategies
Addressing ocean acidification requires
a multi-faceted approach. Reducing
carbon dioxide emissions is crucial to
slow down the rate of acidification.
Additionally, protecting and restoring
marine habitats such as coral reefs and
seagrass beds can help enhance the
resilience of marine ecosystems.
Research into species adaptation and
genetic engineering may also provide
potential solutions to mitigate the
impacts of ocean acidification.

Future Outlook
The future of our oceans depends on
our actions today. Urgent global
efforts are needed to reduce carbon
emissions and limit the extent of
ocean acidification. By
implementing sustainable practices,
protecting marine habitats, and
investing in research and innovation,
we can strive to minimize the silent
threat of ocean acidification and
ensure the long-term health and
resilience of our marine ecosystems.

10. Conclusion
Conclusion
Ocean acidification is an alarming consequence of human
activities, with far-reaching implications for marine life and
ecosystems. The acidification process, driven by carbon dioxide
absorption, poses a significant threat to coral reefs, shell-forming
organisms, and marine food chains. Mitigation strategies and
global cooperation are essential to combat this silent threat and
preserve the health and biodiversity of our oceans for future
generations.
Ocean acidification is an alarming consequence of human
activities, with far-reaching implications for marine life and
ecosystems. The acidification process, driven by carbon dioxide
absorption, poses a significant threat to coral reefs, shell-forming
organisms, and marine food chains. Mitigation strategies and
global cooperation are essential to combat this silent threat and
preserve the health and biodiversity of our oceans for future
generations.
