Carbon dioxide ocean–atmosphere exchange
 
02:48
Atmospheric carbon dioxide is the most important human-made greenhouse gas responsible for global warming. Oceans assist in removing carbon dioxide from the atmosphere: phytoplankton accumulate carbon dioxide through photosynthesis and their chlorophyll colours the ocean’s waters. Satellites use this colour to measure chlorophyll, which helps scientists to calculate how much carbon dioxide is absorbed or emitted.

NOAA Ocean Acidification - The Other Carbon Dioxide Problem

Ocean Acidification
 
05:06
In this video Paul Andersen shows how carbon dioxide in the atmosphere is causing a decrease in the pH of the oceans. The carbon dioxide combines with the water to create carbonic acid which dissociates into bicarbonate and carbonate anions. Decreased pH leads to lower metabolism and immune response in marine species. Increased bicarbonate makes it difficult to form shells and reefs of calcium carbonate.

Can We Store CO2 At Sea? To Answer, Watch Bubbles! - Futuris
 
04:31
Is it possible to safely dispose of excess CO2 by storing it deep in the seabed? And what would be the effect on the ecosystem if this practise was widely used? A European research project called Eco2 carrying out tests in the North Sea and the Mediterranean is seeking to answer these questions. In idyllic waters off Italy's Aeolian Islands researchers are studying the possibilities of Carbon Capture and Storage, or CCS. Their goal is to make a significant contribution to reducing the greenhouse gases causing global warming. The scientists working off the Aeolian Islands are trying to figure out what happens when carbon dioxide leaks into the sea from the seabed. The archipelago was formed by volcanoes and there are big quantities of natural deposits of CO2, making it an ideal research site...

Carbon dioxide dissolves in water
 
01:48
Here is some pure water, which has a pH of 7, shown by using this testing paper and matching the color to the chart on the side of the box. If I take a straw and blow into the water, what gases are going into the water? The one I am interested in is carbon dioxide, which can dissolve in water and react to form an acid. CO2(g) + H2O(l)  H2CO3(aq)  H+(aq) + HCO3‑(aq) So after I blow into the water several times, I should have a solution which is more acid than it was before. Let's check by retesting the pH of the solution. It is now down to 5, rather than the 7 it was as pure water. pH 5 is an acid, so the carbon dioxide has dissolved in the water and reacted. Thus my chemical reaction really has made hydrogen ions in the water, meaning that the carbon dioxide gas dissolved and reacted. CO2(g) + H2O(l)  H+(aq) + HCO3‑(aq) What does this mean about rain which passes through air with CO2 in it ?

The Biological Pump
 
01:35
The amount of carbon dioxide that is in the atmosphere affects global climate. Carbon dioxide is removed from the atmosphere when it dissolved in the surface ocean, but can return to the atmosphere if it remains in the surface. The biological pump is one process that leads to long term carbon storage in the deep ocean. Music credit: Zebra by Beach House, live at KEXP

What are carbon sinks? | Sustainability
 
02:01
In the fight against climate change, nature itself has its own weapons to try to keep the average temperature of the planet from increasing. Carbon sinks are natural (oceans and forests) and artificial deposits (certain technologies and chemicals) that absorb and capture carbon dioxide (CO2) from the atmosphere and reduce its concentration in the air. Carbon sinks are an important help to combat climate change, but they do not solve it. It is essential to abandon our dependence on fossil fuels and to make a strong commitment to renewable energies.

Is Deep Ocean Carbon Storage a Good Idea?
 
04:27
KAUST Research Scientist Jesus Arrieta and a research team investigated dissolved organic carbon located in the deep ocean (below 1,000 meters) that is locked away from the atmosphere. Arrieta discusses two conflicting hypotheses regarding this carbon, the first which proposes it is made of chemical structures impossible for bacteria to degrade, and the second that states that bacteria are able to use the carbon, but it is present in dilute amounts and the bacteria do not expend energy to utilize such dilute compounds. Arrieta's team found that by increasing the concentration of these compounds, bacteria in the deep ocean were able to use them and grew at the same rate as in surface waters, supporting the second hypothesis.

How To Reduce Carbon Dioxide In The Air | Chemistry for All | FuseSchool
 
04:57
Through photosynthesis, plants take in carbon dioxide from the air and split it and use it (and water) to make carbohydrates. So surely plants can help us reduce carbon dioxide in the air? Possibly... But equally, the carbon in plants is then cycled back into the air in the carbon cycle (plants eat them...) Before we started burning fossil fuels, the carbon from dead organisms was locked up underground. Pumping carbon dioxide back into these old gas wells could be an option. Adding iron to seawater is another option so that more algae can grow in the oceans, locking up carbon as it grows. Some of this carbon is cycled back into the carbon cycle, but lots of it will be deposited at the bottom of the ocean as the algae dies. The problem with this is whether it can be carried out on a global scale. Other problems we need to solve are how to capture the carbon before it enters back into the air; will we have to put bags over our car exhaust pipes? and over factory chimneys?!

What Is Ocean Acidification? | A Cartoon Crash Course
 
02:06
There’s a chemical change under way in our oceans. It's called ocean acidification. As the ocean absorbs carbon dioxide from the atmosphere, it's becoming more acidic—eroding the shells of marine life like oysters, clams, and urchins, which are vital to the food web. Scientists predict that ocean acidification could wipe out most coral reefs by the middle of this century, and it’s affecting other animals, too. The good news is that, if we reverse course, the ocean should regain its chemical balance. If not, well, the truth will be a lot scarier than fiction. Nationally syndicated cartoonist Jim Toomey, creator of Sherman's Lagoon, has joined forces with The Pew Charitable Trusts to illustrate "ocean acidification" and other terms associated with our oceans. Watch the full ocean terms video series: http://www.pewtrusts.org/en/research-and-analysis/collections/2016/01/cartoon-crash-course-a-visual-glossary-of-ocean-terminology *TRANSCRIPT* Invisible force invades world, slowly dissolving residents! Sounds like science fiction. Actually, it’s science nonfiction – otherwise known as reality – and it’s happening in our oceans right now. “It” is ocean acidification. “Huh?” The oceans absorbs about a third of the carbon dioxide that spews forth from our cars, power plants, factories and airplanes. That’s over 22 million tons of CO2 every day! But the ocean doesn’t just “absorb” all that CO2. There’s a chemical reaction at work here. Through processes involving hydrogen ions and other science-y nonfiction words, the ocean is becoming more acidic, and that in turn is eroding the shells of vital marine species including clams, oysters, urchins, and pteropods. Oh sure, I know what you’re thinking… “Who cares about a bunch of pteropods?” But these animals are part of the foundation of an enormous food web. And when little things change on a big scale, big changes are sure to follow. The chemical change in our seawater is also having an effect on corals. In fact, scientists say that ocean acidification could wipe out most coral reefs by the middle of this century. It’s affecting larger animals, too. For example, certain fish have a harder time detecting predators. And that’s just for starters. The good news is that with less carbon pollution, the ocean should regain its chemical balance. If not, the truth will be a lot scarier than fiction. Pewtrusts.org/oceanacid

NASA | A Year in the Life of Earth's CO2
 
03:11
An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons. The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office. The visualization is a product of a simulation called a “Nature Run.” The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then left to run on its own and simulate the natural behavior of the Earth’s atmosphere. This Nature Run simulates January 2006 through December 2006. While Goddard scientists worked with a “beta” version of the Nature Run internally for several years, they released this updated, improved version to the scientific community for the first time in the fall of 2014.

Carbon dioxide experiments on the seafloor
 
01:30
This video shows an experiment to study the effects of carbon dioxide (CO2) on deep-sea animals. About one third of the carbon dioxide that humans release into the atmosphere each year is absorbed by the ocean. As more and more carbon dioxide enters the ocean, it effects the plants, animals, and microbes in the water and on the seafloor. This experiment was conducted by James Barry at the Monterey Bay Aquarium Research Institute (MBARI) using a robot submarine. You can see parts of the robot submarine in the foreground at the beginning of the video. At a depth of about 3,300 meters (2 miles) below the surface, the robot submarine touches down on the seafloor, then pours carbon dioxide into white plastic rings. The carbon dioxide turns into a liquid because of the high pressure and near freezing temperature of the surrounding seawater. As the carbon dioxide in the rings gradually dissolves into the surrounding seawater, the seawater becomes more acidic. Around the rings are cages containing deep-sea animals, including hagfish and octopus. An underwater camera near the cages collects video to document any changes in the behavior of the caged animals. A rattail fish (grenadier) swims past the experiment, apparently unaffected. At the end of the video, the robot submarine collects a sample of seafloor mud using a clear plastic push core. This mud is brought back to the surface so that researchers can find out if the acidic seawater affected tiny animals that live in the sediment. MBARI dive video T-0387-05; Lat 36.2 N; Long 122.6 E

Introduction to CO2 Chemistry in Seawater Part 1
 
01:00:02
Over the past twenty years, accurate measurement of the seawater carbon dioxide system has become a high priority for scientists who have worked to understand just how much of the carbon dioxide created by man's activities has ended up in the ocean, where it is distributed, and how it has changed the chemistry of the oceans; a process known as ocean acidification. Andrew G. Dickson, Professor of Marine Chemistry at the Scripps Institution of Oceanography UC San Diego, has been measuring carbon dioxide in seawater for over 30 years. In this two-part series, he introduces the basic chemical processes underlying the study of carbon dioxide in the oceans, and provides an overview of the experimental techniques that are in use to measure the levels of carbon dioxide in seawater indicating how a newcomer to this field might make decisions as to what research tools best suit them.

FACEBOOK: https://www.facebook.com/DIYAQUAPROS TWITTER: @DIYAQUAPROS It's vital to have a good understanding of how CO2 reacts with water in the aquarium. Supplementing CO2 via a DIY or Pressurized system will have an effect on water parameters and can lead to trouble if you are not prepared. This video highlights the main reaction of CO2 mixing with water and how pH plays a role in the conversion of CO2 into the different forms of dissolved inorganic carbon (DIC). When CO2 is supplemented in the planted aquarium, the initial effect is drop in pH due to the formation and quick disassociation of protons from carbonic acid, the compound that forms as a result of CO2+H2O. The resulting compound is bicarbonate, an intermediate molecule in the DIC equilibrium. For aquariums with a neutral pH ~7 this will be the predominant form of carbon that results from the CO2 supplementation. Bicarbonate acts as a pH buffer and helps to regulate the severity of pH swings that occur during different parts of the day and night in the aquarium. Carbonate is the final piece of the puzzle, but is rarely seen in high quantities in the freshwater environment. Carbonate formation will only occur at a high pH, generally ~8.5 and above. This compound often precipitates out of solution when in the presence of high Ca2+ levels.

Carbon dioxide released from the ocean may have ended last ice age, says recent study
 
01:15
Recent research conducted by the University of Southampton and published in Nature magazine suggests that carbon dioxide released from the ocean played a large role in ending the most recent ice age. The studies were based on analyzing the calcium carbonate shells in plankton that lived in the ocean thousands of years ago. By examining the shells of microbes called foraminifera, which preserves the ratio of chemicals in seawater as they grow, researchers were able to determine the concentration of dissolved inorganic carbon in ocean water thousands of years ago. Research points to a huge, sudden rise in dissolved carbon concentrations in the surface water of the Atlantic Ocean and in the eastern equatorial Pacific Ocean at the end of the last ice age. This sudden rise in concentration corresponds to the simultaneously increasing levels of atmospheric carbon dioxide. Based on these findings, scientists suggest that at that point in time, upwellings in the Southern Atlantic Ocean and the eastern Pacific Ocean occurred. This caused isolated reservoirs of cold, carbon-rich waters to churn up to the surface. There’s a high concentration of dissolved carbon at greater depths in the ocean because waste and decay fall to the bottom of the ocean and some of the carbon is further retained in calcium carbonate shells like those examined in this recent study. The upwelling reconnected large concentrations of carbon with the water surface where it readily transformed into carbon dioxide and was absorbed into the atmosphere. As a greenhouse gas, carbon dioxide in the atmosphere absorbed solar energy and thereby warmed the atmosphere. As the oceans began to warm as a consequence, the oceans are also unable to absorb as much atmospheric carbon dioxide and this continues to lead to an increasingly warm atmosphere. ----------------------------------------­--------------------- Welcome to TomoNews, where we animate the most entertaining news on the internets.

Ocean Acidification: The Other Carbon Dioxide Problem [1080p]
 
03:58
Fundamental changes in seawater chemistry are occurring throughout the world's oceans. Since the beginning of the industrial revolution, the release of carbon dioxide (CO2) from humankind's industrial and agricultural activities has increased the amount of CO2 in the atmosphere. The ocean absorbs almost a third of the CO2 we release into the atmosphere every year, so as atmospheric CO2 levels increase, so do the levels in the ocean. Initially, many scientists focused on the benefits of the ocean removing this greenhouse gas from the atmosphere. However, decades of ocean observations now show that there is also a downside — the CO2 absorbed by the ocean is changing the chemistry of the seawater, a process called ocean acidification. This change in the ocean's chemistry will have profound effects on life in the ocean, and those who depend on it. credit: NOAA source: http://www.nnvl.noaa.gov/MediaDetail.php?MediaID=722&MediaTypeID=2

Films on Ocean Warming and Acidification "Corrosive Oceans": addresses wide-held concerns about the impact that ocean acidification may have on marine life - today and in the near future. The film explains the relationship between increasing levels of CO2 in the atmosphere and the health of marine organisms - in particular calcifying organisms such as corals and shellfish. Scientific findings on ocean acidification are still predominantly based on experimental research in the laboratory. More data from the field is needed to verify the results of these studies. The film accompanies a group of scientists while they are taking a close look at under water sites in the Mediterranean Sea. These scientists want to find out whether marine life has already been affected by an increase of pH in the waters. Another group of scientists is shown as they are observing marine life close to undersea volcanic vents. Their research gives an indication of how the conditions for marine life may change in the future if the levels of CO2 in the atmosphere continue to increase. - See more at: http://www.eusem.com/main/CE/SIP_C5pub2012

Ocean Circulation Plays an Important Role in Absorbing Carbon from the Atmosphere
 
00:42
The oceans play a significant role in absorbing greenhouse gases, like carbon dioxide, and heat from the atmosphere. This absorption can help mitigate the early effects of human-emissions of carbon dioxide. The Atlantic Meridional Overturning Circulation acts as a conveyor belt of ocean water from Florida to Greenland. Along the journey north, water near the surface absorbs greenhouse gases, which sink down as the water cools near Greenland. In this way, the ocean effectively buries the gases deep below the surface.

Seasonal Changes in Carbon Dioxide
 
01:21
Carbon dioxide is the most important greenhouse gas released to the atmosphere through human activities. It is also influenced by natural exchange with the land and ocean. This visualization provides a high-resolution, three-dimensional view of global atmospheric carbon dioxide concentrations from September 1, 2014 to August 31, 2015. The visualization was created using output from the GEOS modeling system, developed and maintained by scientists at NASA. The height of Earth’s atmosphere and topography have been vertically exaggerated and appear approximately 400 times higher than normal to show the complexity of the atmospheric flow. Measurements of carbon dioxide from NASA’s second Orbiting Carbon Observatory (OCO-2) spacecraft are incorporated into the model every 6 hours to update, or “correct,” the model results, called data assimilation. As the visualization shows, carbon dioxide in the atmosphere can be mixed and transported by winds in the blink of an eye. For several decades, scientists have measured carbon dioxide at remote surface locations and occasionally from aircraft. The OCO-2 mission represents an important advance in the ability to observe atmospheric carbon dioxide. OCO-2 collects high-precision, total column measurements of carbon dioxide (from the sensor to Earth’s surface) during daylight conditions. While surface, aircraft, and satellite observations all provide valuable information about carbon dioxide, these measurements do not tell us the amount of carbon dioxide at specific heights throughout the atmosphere or how it is moving across countries and continents. Numerical modeling and data assimilation capabilities allow scientists to combine different types of measurements (e.g., carbon dioxide and wind measurements) from various sources (e.g., satellites, aircraft, and ground-based observation sites) to study how carbon dioxide behaves in the atmosphere and how mountains and weather patterns influence the flow of atmospheric carbon dioxide. Scientists can also use model results to understand and predict where carbon dioxide is being emitted and removed from the atmosphere and how much is from natural processes and human activities. Carbon dioxide variations are largely controlled by fossil fuel emissions and seasonal fluxes of carbon between the atmosphere and land biosphere. For example, dark red and orange shades represent regions where carbon dioxide concentrations are enhanced by carbon sources. During Northern Hemisphere fall and winter, when trees and plants begin to lose their leaves and decay, carbon dioxide is released in the atmosphere, mixing with emissions from human sources. This, combined with fewer trees and plants removing carbon dioxide from the atmosphere, allows concentrations to climb all winter, reaching a peak by early spring. During Northern Hemisphere spring and summer months, plants absorb a substantial amount of carbon dioxide through photosynthesis, thus removing it from the atmosphere and change the color to blue (low carbon dioxide concentrations). This three-dimensional view also shows the impact of fires in South America and Africa, which occur with a regular seasonal cycle. Carbon dioxide from fires can be transported over large distances, but the path is strongly influenced by large mountain ranges like the Andes. Near the top of the atmosphere, the blue color indicates air that last touched the Earth more than a year before. In this part of the atmosphere, called the stratosphere, carbon dioxide concentrations are lower because they haven’t been influenced by recent increases in emissions. This narrated version of the visualization was created specifically to support a series of papers in the journal Science and for submission to SIGGRAPH 2017's Computer Animation Festival.

Deep-sea bacteria could help neutralize greenhouse gas
 
02:38
GAINESVILLE, Fla. — A bacteria plucked from the bottom of the ocean could be put to work neutralizing large amounts of industrial carbon dioxide, a group of UF Health researchers has found. Carbon dioxide, a major contributor to the buildup of atmospheric greenhouse gases, can be captured and neutralized in a process known as sequestration. But converting the carbon dioxide into a harmless compound requires a durable, heat tolerant enzyme. That’s where the bacteria studied by UF Health researchers come into play. The bacteria — Thiomicrospira crunogena — produce carbonic anhydrase, an enzyme that helps break down carbon dioxide in organisms. So what makes the deep-sea bacteria so attractive? It lives in hydrothermal vents, so the enzyme it produces is accustomed to high temperatures. That’s exactly what’s needed for the enzyme to work during the process of reducing industrial carbon dioxide, said Robert McKenna, Ph.D., a professor of biochemistry and microbiology in the UF College of Medicine. “This little critter has evolved to deal with those problems. It has already adapted to some of the conditions it would face in an industrial setting,” he said. The findings by the McKenna’s group, which included graduate research assistant Brian Mahon and graduate student Avni Bhatt, were published recently in the journal Biological Crystallography. The chemistry of sequestering works this way: The enzyme, carbonic anhydrase, catalyzes a chemical reaction of carbon dioxide and water. The carbon dioxide interacts with the enzyme, converting the greenhouse gas into bicarbonate. The bicarbonate can then be further processed into products such as baking soda and chalk.
