There are many types of Coral Reefs
Fringing reef– a reef that is directly attached to a shore or borders it
with an intervening shallow channel or lagoon.
Barrier reef– a reef separated from a mainland or island shore by a
Patch reef – an isolated, often circular reef, usually within a lagoon or
Apron reef – a short reef resembling a fringing reef, but more sloped;
extending out and downward from a point or peninsular shore.
Bank reef – a linear or semi-circular shaped-outline, larger than a
Ribbon reef – a long, narrow, somewhat winding reef, usually
associated with an atoll lagoon.
Atoll reef – a more or less circular or continuous barrier reef extending
all the way around a lagoon without a central island.
Table reef – an isolated reef, approaching an atoll type, but without a
Pacific including Australia
Atlantic and Caribbean
Close to equator ,Water Temperatures
are constant, the water is low in
nutrients, the waters are shallow
*must be photic (penetrated by the sun)
Macro & Phytoplankton .Nurseries for
young fish Insects & Zooplankton.
25-30 degrees Celsius
Rocks,Sand, the soil is wet, dead organisms.
Dominate geographic features
Seagrass Meadows & Mangroves
Solar radiation causes some bleaching
Coralline Algae (when the algae dies the coral
reefs bleach,get hard and die.)
Seagrass (Seagrass meadows are dieing fast and
when those die the organisms living in it die
because the seagrass was the only source of
food they ate.)
* Flora (certain plant life)
*Fauna (certain wildlife)
Without the coralline algae the coral
wouldn’t turn colors and if the coralline
algae die or disappear the corals bleach
*Protect shores from the impact of waves and from
storms. Benefits humans in the form of food and
medicine. Provide economic benefits to local
communities from tourism.
When deforestation happens the are no more roost
in the water to hold the soil in place. Causing run
off and the soil runoff cover the corals
smothering them and eventually killing them.
84 million acres underwater and 99,500 sq. ft. was
saved to preserve the coral reefs. Known to be
the largest Preserve in history.
The climate change is the biggest danger
factor to coral reefs. When CO2 dissolves
in seawater it makes it more acidic.
Affecting the way in which the coral forms.
Reefs consist of calcium carbonate,
produced by tiny creatures called coral
polyps. Researchers found that as the
CO2 dissolves in the water, it increases
the acidity level causing the coral
formation to slow down.
The National Coral Reef Institute
Established by Congressional mandate in
1998. NCRI assesses, monitors, and
restores coral reefs through basic and
applied research through training and
Reef Ball Foundation (1993)
Publicly supported non-profit organization
that functions as an international
organization. The foundation uses article
reef technology, and transplant
technology, public education and
community training to build, restore and
protect coral reefs. In over 70 countries.
