The ocean, that vast body of water covering 71 percent of the Earth's surface, is divided
into four major basins: the Pacific, Atlantic, Indian, and Arctic Oceans. These large
basins are interconnected with various shallow seas, such as the Mediterranean Sea, the
Gulf of Mexico, and the South China Sea. Oceans and seas abound with life, ranging
from microscopic unicellular (one-celled) organisms to multicellular (many-celled)
animals.
Algae is an important life form in the ocean. Life in the ocean is maintained in balance
by forces of nature and by predator
prey relationships, unless some external pressures
upset the balance. When a balance upset leads to conditions more favorable for the
reproduction and growth of algae, an explosive increase in the number of algal cell
density occurs. Such rapid increases in the algae population are called algal blooms.
During a bloom, a liter of water may contain millions of algae. The most widely
publicized type of algal bloom is associated with species that produce a toxin (chemical
substance) harmful to animals that feed on the algae (and hence is known as a harmful
algal bloom), and/or algae that cause a tint in the water because of thephotosynthetic
pigments they contain. The latter commonly is known as a "red tide," but different
pigments can turn the water red, brown, purple, orange, or yellow. Depending on the
circumstances and the species present, a red tide may or may not be harmful. Although
not all algal blooms in the ocean produce highly visible effects nor are all blooms
harmful, they nonetheless affect life in the ocean and on land in both beneficial and
harmful ways.

3/21
In February 2002, the massive die-off and decay of algae from a nearshore harmful algal
bloom (a "red tide") caused a rapid reduction in the water's dissolved oxygen
concentration, driving tens of thousands of rock lobsters to "walk out of the sea" near
the coastal town of Elands Bay in South Africa's Western Cape province. The lobsters in
search of oxygen moved toward the breaking surf, but were stranded when the tide went
out. Government and military staff attempted to save some of the lobsters, but others
were collected for food. A similar stranding from a massive red-tide event occurred at
Elands Bay in 1997.
Requirements for a Bloom
Algae require warmth, sunlight, and nutrients to grow and reproduce, so they live in the
upper 60 to 90 meters (200 to 300 feet) of ocean water. The upper layer of water, the
epipelagic zone, is rich in oxygen, penetrated by sunlight, and warmer than water at
lower levels. As algae and other organisms that live in the ocean die, they fall to thebottom of the ocean, where they decay and release the compounds from which they were
made. Under certain conditions, these nutrients can deplete the oxygen in the water.
Temperature and salt concentration determine the density of water and how water
moves (currents). Cold water is denser (heavier) and sinks from the surface
7/31/2019 Algal Blooms in the Ocean
4/21
(downwelling). Other water moves across to replace it. Eventually, water at the surface
is replaced by water that has risen, or upwelled, from the bottom to the surface
somewhere else in the ocean. These upwellings bring nutrient-rich waters to the top.
This increase in nutrients can trigger algae blooms.
An increase in nutrients also may be caused by activities of humans, such as runoff from
animal farms or fertilized croplands and lawns, or atmospheric deposition of sulfur and
nitrogen compounds or oxides derived from the burning offossil fuel . These nutrients
lead to blooms in coastal waters to a greater extent than in the open ocean.
However, some of these nutrients do find their way to the open ocean far from shore,
and contribute to the formation of blooms in the open ocean. Their movement is aided
by the wind and by ocean currents. Algae blooms in the open ocean are not usually
harmful; instead, they provide many benefits, largely deriving from the fact that the
open ocean is relatively unproductive (low in nutrients).
Algae and Photosynthesis
Algae are referred to as plants because, like plants, they produceorganic compounds
from inorganic compounds (carbon dioxide and water) by capturing and using the
energy from sunlight. Most algae are eukaryotic , an exception being the blue-greenalgae (cyanobacteria).
Photosynthesis takes place in organelles called chloroplasts in eukaryotic cells.
Chloroplasts contain an outer and an inner membrane and pancakeshaped structures
called thylakoids. Energy is captured from sunlight by pigments (chlorophylls a and b
and carotenoids) stored in the thylakoids.
Photosynthesis occurs in two stages commonly referred to as the light reactions (light isrequired) and the dark reactions (no light is directly required). During the light
reactions, energy captured from sunlight is used to split (dissociate) water molecules.
Electrons released from this reaction are passed down a series of electron carrier
molecules, leading to the storage of the energy in the form of ATP (adenosine
7/31/2019 Algal Blooms in the Ocean
5/21
triphosphate). This is the form in which living organisms store energy to be used
immediately for carrying out chemical reactions and other activities.
Oxygen is produced as a byproduct of the light reactions. During the dark reactions
(Calvin cycle), six molecules of carbon dioxide are used to make sugar (glucose).
Because algae use carbon dioxide and release oxygen as a product of the light reactions,
these plants play an important role in maintaining the proper concentrations of carbon
dioxide and oxygen in the environment, via the carbon cycle and oxygen cycle.
Algae, like green plants, produce the first organic compounds in the food chain and
thus are referred to as primary producers. Other organisms cannot use inorganic
molecules to make the organic compounds that they need for life, and therefore depend
on algae and other plants as the initial source of organic compounds. These organisms
either eat algae to obtain organic compounds, or obtain them from the water when they
are released after the algae die.
Types of Algae That May Bloom
Cyanobacteria.
Cyanobacteria, also known as blue-green algae, are one of the oldest known types ofalgae and are believed to have played a major role in the addition of oxygen to the
Earth's early atmosphere. Some cyanobacteria carry out nitrogen fixation, which is the
conversion of nitrogen gas into nitrogen compounds that can be used by other primary
producers.
Diatoms.
Diatoms are unicellular and have a cell wall composed of silica, a glass-like material,
which comprises a shell-like structure called a frustule.
7/31/2019 Algal Blooms in the Ocean
6/21
Coccolithophore blooms are identifiable via space-based remote sensing because their
external plates of calcium carbonate, called coccoliths, backscatter light from the water
column to create a bright optical effect. This bloom (the cloudy swirl in lower lefthand
corner) occurred in summer 2001 in the Celtic Sea off England's southwestern coast.
When diatoms die, the frustules settle to the bottom of the ocean floor and combine with
the soil to form diatomaceous earth. Diatomaceous earth is used in products such as
filters for swimming pools, as temperature and sound insulators, and as an abrasive in
toothpaste.
Dinoflagellates.
Dinoflagellates have two unequal flagella that help them direct their movement. Many
of these organisms contain colored pigments that cause the water to appear colored
when these organisms bloom, leading to the terms "red tide" or "brown tide," for
example. Some dinoflagellates live in close association with marine animals, such as
sponges, sea anemones, giant clams, and corals. The golden-brown photosynthetic cells
found in these animals, called zooxanthellae, actually are dinoflagellates.
Coccolithophores.
Coccolithophores are cells covered with button-like structures called coccoliths made of
calcium carbonate. The coccoliths give the ocean a milky white or turquoise appearance

during intense blooms. The long-term flux of coccoliths to the ocean floor is the main
process responsible for the formation of chalk and limestone.
Coccolithophores and some other algae participate in the sulfur cycle and produce the
gas dimethyl sulfide. This is the primary way that sulfur is carried between ocean and
land.
Dimethyl sulfide leaves the surface of the water and reacts with oxygen in the
atmosphere to form tiny sulfuric acid droplets. These droplets are carried over land and
fall back to land in the form of precipitation. They also aid in the formation of clouds,
which partially block the transmission of harmful ultraviolet light that penetrates the
surface water. Cloud formation also is thought to encourage surface winds that promote
the movement of surface water, leading to upwellings that bring nutrients to the surface.
Benefits of Algal Blooms
Algal blooms provide large concentrations of algae that produce organic compounds
needed by higher organisms, ranging from oysters, clams, and mussels to human beings.
For this reason, productivity increases in areas where algal blooms occur. More algae in
the water means that more carbon dioxide is used from the atmosphere and that more
oxygen is released into the atmosphere. Oxygen is necessary for many living things,including humans. As noted previously, the production of dimethyl sulfide gas helps
protect algae from harmful ultraviolet rays so they remain healthy and thus are able to
continue the cycle of sustaining life on Earth.
Even in the coldest parts of the ocean, algae provide the primary source of organic
material to animals at the bottom of the food chain. Organic materials are moved up the
food chain as higher organisms feed on those lower down the chain. For example, algae
have been found in Antarctic sea ice. As sea water freezes, algae living in the water arefrozen in the ice, where they later can be released during a thaw. These algae are a vital
source of food for krill, the shrimp-like organisms eaten by penguins, seals, seabirds,
and whales.

article is good and so much informative Dinoflagellates have two unequal flagella that help
them direct their movement. Many of these organisms contain colored pigments that causethe water to appear colored when these organisms bloom, leading to the terms "red tide" or"brown tide," for example. Some dinoflagellates live in close association with marineanimals, such as sponges, sea anemones, giant clams, and corals. The golden-brownphotosynthetic cells found in these animals, called zooxanthellae, actually aredinoflagellates.Coccolithophores.

Even in the coldest parts of the ocean, algae provide the primary source of organic materialto animals at the bottom of the food chain. Organic materials are moved up the food chainas higher organisms feed on those lower down the chain. For example, algae have beenfound in Antarctic sea ice. As sea water freezes, algae living in the water are frozen in the ice,
where they later can be released during a thaw. These algae are a vital source of food for

In October 1998, U.S. Senator Daniel Patrick Moynihan testified before Congress on
acid rain. A longtime champion of the issue, Moynihan stated that "As far back as the
1960s, fishermen in the Adirondacks began to complain about more than 'the big one
that got away.' Fish, once abundant in the pristine, remote Adirondack lakes, were not
just getting harder to catch. They were gone."
The issue of acid rain emerged in the United States in the mid-1970s. At the time, little
was known about the magnitude and distribution of acid rain or about its impacts on
terrestrial (land-based) and aquatic ecosystems . However, many believed that acid
rain and the air pollutants that caused it posed a threat to forests, aquatic life, crops,
structures (e.g., buildings), cultural artifacts (e.g., statues and monuments), and human
health.
Since the 1970s, acid rain has been addressed in the United States through hundreds of
millions of dollars of research, passage of laws, and implementation of regulatory
programs. However, Senator Moynihan's 1998 remark is stark testimony to the fact that
acid rain continues to have a negative effect on natural resources, and addressing the
problem is an enduring public policy dilemma.

Rain, snow, sleet, and other forms of precipitation are naturally slightly acidic because
of chemical reactions with carbon dioxide and other naturally occurring substances in

the atmosphere. But this natural acidity can be increased by human-induced air
pollution. Acid deposition or "acid rain" occurs when emissions of sulfur dioxide (SO2 )
and oxides of nitrogen (NO x) in the atmosphere react with water, oxygen, and oxidants
to form mild solutions of sulfuric acid or nitric acid. Sunlight increases the rate of most
of these reactions. These compounds fall to Earth and are deposited in either wet form
(e.g., rain, snow, sleet, and hail), known as wet deposition, or dry form (e.g., particles,
gases, and vapor), known as dry deposition. Cloud or fog deposition, a form of wet
deposition, occurs at high elevations and in coastal areas.
In the United States, nearly two-thirds of annual SO 2 emissions and just over one-fifth
of NO xemissions are produced by electric utility plants that burn fossil fuels .
Transportation sources (e.g., cars, trucks, and other vehicles) account for more than half
of NO xemissions. Ammonia emissions derive largely from livestock waste and fertilized
soil. Industrial combustion
A sign in Nova Scotia, Canada proclaims the potential effect of acid rain on a local river and its
salmon runs. Acidified waters can be harmful or even deadly to salmon populations.
and industrial processes are the other major categories of emission sources. Acid rain is a
regional problem because prevailing winds can transport SO 2 and NO xemissions over hundreds
of kilometers, sometimes crossing state, national, and international borders.

Buffering capacity depends on the thickness and composition of the soil as well as the
type of bedrock beneath the forest floor.
Lakes and streams become acidic ( pH decreases) when the water itself and its
surrounding soil cannot neutralize the acidity in the rain. Differences in soil buffering
capacity are an important reason that some areas receiving acid rain show damage,
whereas other areas receiving about the same amount of acid rain do not appear to be
harmed.
Several regions in the United States contain many of the surface waters sensitive to
acidification. They include the Adirondacks and Catskill Mountains in New York State,
the mid-Appalachian highlands, the upper Midwest, and mountainous areas of the
western United States. In areas such as the northeastern United States, where soil
buffering capacity is low, some lakes have a pH value of less than 5. With a pH of 4.2,
Little Echo Pond in Franklin, New York was one of the most acidic lakes reported as of
2002.
Ecosystem Impacts.
Acid rain is not the sole cause of low pH in lakes and streams. There are many natural
sources of acidity that can drive down pH to low levels (as low as 4) even in the absenceof acid rain: for example, organic acid inputs or mineral veins in underlying geologic
materials. Similarly, natural sources of buffering capacity such as limestone bedrock can
push pH to as high as 8. Notwithstanding these natural influences in specific locations,
lakes and streams generally have pH values from 6 to 8. Hence, reductions in pH due to
human-induced acid rain create an imbalance in the chemistry and ultimately the entire
ecosystem of a lake or stream.
Acid rain causes a cascade of effects that harm or kill individual fish, reduce fishpopulations, completely eliminate fish species from a waterbody, and decrease
biodiversity. As acid rain flows through soils in a watershed, aluminum and other
metals are released from soils into the lakes and streams located in that watershed.
Thus, as a lake or stream becomes more acidic (has lower pH), aluminum levels
increase. Both low pH and increased aluminum levels are directly toxic to fish. In
http://www.waterencyclopedia.com/A-Bi/Biodiversity.htmlhttp://www.waterencyclopedia.com/A-Bi/Biodiversity.htmlhttp://www.waterencyclopedia.com/A-Bi/Biodiversity.html7/31/2019 Algal Blooms in the Ocean
14/21
addition, low pH and increased aluminum levels cause chronic stress that may not kill
individual fish but may make fish less able to compete for food and habitat.
The impact of declining pH varies because not all aquatic organisms can tolerate the
same amount of acid. For example, frogs are better able than trout to tolerate somewhat
acidified water. Generally, the young of most species are more sensitive to
environmental conditions than adults.
As pH levels decline, acid-sensitive species may attempt to migrate to better habitat, or,
if blocked from migration, will likely die. At pH 5 and below, most fish species
disappear, and ecosystem-level processes are affected. Some acid lakes and streams
contain no fish.
Acidified lakes and streams can be treated with agricultural lime in an attempt to counteract the
acidity. Such temporary and localized measures are not as effective as emissions reductions in
addressing the long-term and geographically widespread ecological impacts of acid rain.
Effects on Forests and Soils
Acid rain has been implicated in forest and soil degradation in many areas of the easternUnited States, particularly high elevation forests of the Appalachian Mountains from
Maine to Georgia. Acid rain does not usually kill trees directly. Instead, it weakens trees
by damaging their foliage, limiting the nutrients available to them, or exposing them
to toxic substances slowly released from the soil. Quite often, injury or death is a result
7/31/2019 Algal Blooms in the Ocean
15/21
of acid rain in combination with other environmental stressors, such as insects, disease,
drought, or very cold weather.
Chemicals in watershed soils that provide buffering capacity (such as calcium and
magnesium) are also important nutrients for many species of trees. As forest soils
receive year after year of acid rain, these chemicals are washed away, depriving trees
and other plants of essential soil nutrients. At the same time, acid rain causes the release
of dissolved aluminum into the soil water, which can be toxic to trees and plants. The
chemicals that provide buffering capacity take many decades to replenish through
gradual natural processes, such as theweathering of limestone bedrock.
Trees also can be damaged by acid rain even if the soil is well buffered. Mountainous
forests often are exposed to greater amounts of acidity because they tend to be
surrounded by acidic clouds and fog. Essential nutrients in foliage are stripped away
when leaves and needles are frequently bathed in acid fog, causing discoloration and
increasing the potential for damage by other environmental factors, especially cold
weather.
Effects on Human Health and Human Environments
The pollutants that cause acid rain also damage human health. These gases interact inthe atmosphere to form fine sulfate and nitrate particles that can be inhaled deep into
the lungs. Scientific studies show relationships between elevated levels of fine particles
and increased illness and premature death from heart disease and lung disorders, such
as bronchitis. In addition, nitrogen oxides react in the atmosphere to formozone ,
increasing risks associated with lung inflammation, such as asthma.
Sulfates and nitrates in the atmosphere also contribute to reductions in visibility.
Sulfate particles account for 50 to 70 percent of decreased visibility in eastern U.S.national parks, such as the Shenandoah and the Great Smoky Mountains. In the western
United States, nitrates and carbon also play roles, but sulfates have been implicated as
an important source of visibility impairment in some national parks, such as the Grand
Canyon.

Wet and dry acid deposition contribute to the corrosion of metals (such as bronze) and
the deterioration of paint and stone (such as marble and limestone). These effects
seriously reduce the value to society of buildings, bridges, cultural objects (such as
statues, monuments, and tombstones), and automobiles.
1990 Clean Air Act Amendments: Title IV
In 1990, the U.S. Congress took action intended to address acid rain issues, passing the
Clean Air Act Amendments (CAAA) (42 U.S.C. 7651). The purpose of the Acid Rain
Program (Title IV of the 1990 amendments) was to address the adverse effects of acid
rain by reducing annual emissions of sulfur dioxide (SO 2 ) and nitrogen oxides (NO x)
the main air pollutants that cause the problemsfrom stationary power generation
sources.
Implemented by the U.S. Environmental Protection Agency starting in 1995, the
program consists of two major components. The SO 2 emission reduction program
employs a two-phase cap-and-trade approach to reduce total annual SO 2 emissions by
10 million tons below 1980 levels by 2010 (roughly a 40-percent reduction in total
emissions). When the SO 2 emission reduction is fully implemented in approximately
2010, electric utility emissions will be capped at 8.95 million tons per year (representing
approximately a 50-percent reduction in emissions from this sector).
The NO xemission reduction program aims to reduce annual NOxemissions from coal-
fired electric utility boilers by 2 million tons below what they would have been without
Title IV. The NO xcomponent of the program does not include a cap on NOxemissions
or any emissions trading provisions.
Emissions Trading.
In establishing the Acid Rain Program, Congress chose to utilize an innovative
environmental management approach known as capand-trade, or emissions trading, to
reduce SO 2 emissions. Emissions trading is a departure from more traditional
"command and control" regulatory approaches in which the government commands
industry to install particular control technologies at specific plants in order to reduce
7/31/2019 Algal Blooms in the Ocean
17/21
7/31/2019 Algal Blooms in the Ocean
18/21
required emission levels, resulting in early achievement of human health and
environmental benefits. In 2001, SO 2 emissions from power generation were more than
6.7 million tons below 1980 levels.
Emissions of NO xhave been reduced by 1.5 million tons from 1990 levels (about 3
million tons lower than projected growth). Because the NOxcomponent of the program
includes no cap, there is no guarantee that NO xemissions will stay at these low levels;
without a cap, emissions may increase as power generation increases.
Because of the reduction in SO 2 emissions, acidity of rainfall in the eastern United
States has dropped by up to 25 percent. As a consequence, some sensitive lakes and
streams in New England are showing signs of recovery. Further, sulfate concentrations
in the air have decreased, leading to improved air quality and associated benefits to
public health, such as fewer irritations or aggravations to respiratory conditions (e.g.,
asthma and chronic bronchitis). Finally, visibility has improved in some parts of the
eastern United States, including areas with scenic vistas, such as Acadia National Park
in coastal Maine.
Although the Clean Air Act has had positive effects, emissions and acid deposition
remain high compared to background conditions. The rate and extent of ecosystem
recovery from acid deposition are directly related to the timing and degree of emissions
reductions. Research suggests that deeper emissions cuts will lead to greater and faster
recovery from acid deposition in the northeastern United States.

ACID RAIN AND THE U.S. CAPITOL BUILDING
The buildings and monuments of Washington, D.C. use many types of stone. Marble and
limestone structures are the most likely to show damage caused by acid precipitation
and urban pollution. They are vulnerable to accelerated deterioration because they are
composed primarily of the mineral calcite (calcium carbonate), which dissolves readily
in weak acid.
The United States Capitol building shows evidence of stone deterioration. For example,
preferential dissolution of calcite (where the silicate mineral inclusions remain) has
caused pockmarks in marble columns and balustrades and their square bases. Although
stone deterioration has many causes, both natural and human-induced, it is almost
certain that some deterioration can be attributed to acid rain.
