It is found in the animal kingdom in insects inside sea shells and in feathers and is seen also in some plants.

#Mangroves protecting corals from climate changecertain types of corals invertebrates of the sea that have been On earth for millions of years appear to have found a way to survive some of their most destructive threats by attaching to and growing under mangrove roots.
Scientists with the U s. Geological Survey and Eckerd College recently published research on a newly discovered refuge for reef-building corals in mangrove habitats of the U s. Virgin islands.
More than 30 species of reef corals were found growing in Hurricane Hole a mangrove habitat within the Virgin islands Coral reef National monument in St john. Corals are animals that grow in colonies forming reefs over time as old corals die
However some of their most widespread threats involve warming ocean temperatures solar radiation and increased ocean acidification.
No coral reefs have been identified to date that protect from rising ocean temperatures acidification and increased solar radiation like these mangrove habitats in St john. Story Source:
#Food, fuel and more will be produced in sea farms of futuremeet the farm of the future where common seaweed is being upgraded from an environmental problem to a valuable natural resource and raw material.
The excessive fertilisation (eutrophication) of our seas results in an over-production of algae commonly known as seaweed.
Almost three quarters of the earth's surface is covered by sea and the seas possess as great a production capacity as the land.
At the present time humankind utilises 40 per cent of the production from land-based ecosystems
whereas only 1 per cent of the seas'ecosystems are utilised currently. Unfortunately this percentage at present consists largely of ruthless exploitation;
where the fishing industry trawls up every living thing and hoovers the sea bottoms. We really need new solutions such as harvesting the excess algae for fuel
since they form secondary reefs in free bodies of water. This sort of reef attracts fish and other animal species
. What's more we're also acting to help the environment. Partly when we make use of the excess algae
and partly when we cultivate algae that actually absorb nitrogen and phosphorus from the sea.
and are able to grow in the sea. When the algae after about six months have grown on the ropes they are harvested

Record greenhouse gas levels impact atmosphere and oceans, WMO report findsthe amount of greenhouse gases in the atmosphere reached a new record high in 2013 propelled by a surge in levels
Concentrations represent what remains in the atmosphere after the complex system of interactions between the atmosphere biosphere and the oceans.
About a quarter of the total emissions are taken up by the oceans and another quarter by the biosphere reducing in this way the amount of CO2 in the atmosphere.
The ocean cushions the increase in CO2 that would otherwise occur in the atmosphere but with far-reaching impacts.
The current rate of ocean acidification appears unprecedented at least over the last 300 million years according to an analysis in the report.
Carbon dioxide remains in the atmosphere for many hundreds of years and in the ocean for even longer.
Past present and future CO2 emissions will have a cumulative impact on both global warming and ocean acidification.

It is high time the ocean as the primary driver of the planet's climate and attenuator of climate change becomesa central part of climate change discussions said Wendy Watson-Wright Executive secretary of the Intergovernmental Oceanographic Commission of UNESCO.

The ocean currently absorbs one-fourth of anthropogenic CO2 emissions reducing the increase in atmospheric CO2 that would
Enhanced ocean CO2 uptake alters the marine carbonate system and lead to increasing acidity. The ocean's acidity increase is already measurable as oceans take up about 4 kilogrammes of CO2 per day per person.
The current rate of ocean acidification appears unprecedented at least over the last 300 million years based on proxy-data from paleo archives.
In the future acidification will continue to accelerate at least until mid-century based on projections from Earth system models.
The potential consequences of ocean acidification on marine organisms are complex. A major concern is the response of calcifying organisms such as corals algae mollusks

Subsurface warming in the ocean explains why global average air temperatures have flatlined since 1999 despite greenhouse gases trapping more solar heat at Earth's surface.
We looked at observations in the ocean to try to find the underlying cause. The results show that a slow-moving current in the Atlantic which carries heat between the two poles sped up earlier this century to draw heat down almost a mile (1500 meters.

The increased use of groundwater for irrigation also results in a rise in sea levels: According to DÃ ll's calculations sea level rise due to groundwater depletion was 0. 31 millimetres per year during the period from 2000 to 2009.

We must immediately address the grazing problem for the reefs to stand any chance of surviving future climate shifts.

by the time it reaches seafloora fraction of the carbon that finds its way into Earth's oceans--the black soot
and hitches a ride to the ocean floor on passing particles. The study by scientists from Rice university the University of California Irvine and the University of South carolina offers the first detailed analysis of how black carbon gets into deep ocean sediments as well as an accounting of the types
and amounts of black carbon found in those sediments. Our previous work showed that the black carbon in ocean sediments is said ancient lead investigator Ellen Druffel the Fred Kavli Professor of Earth System Science at UC Irvine.
It's anywhere from 2000 to 5500 years older than the organic carbon in the same sediments.
or it stays trapped somewhere else--like the soil--for thousands of years before it enters the ocean.
This new study offers the most complete picture yet of how black carbon finds its way into deep ocean sediments.
Our aim was to show how the black carbon cycle likely works in the ocean Druffel said.
This helps us narrow down the role of the ocean as a sink for both soot and charcoal.
Black carbon's journey to the bottom of the ocean begins when the material enters the water.
Airborne soot gets into the ocean via rainfall and runoff from streams. Though charcoal residue can stay trapped in soils for thousands of years runoff
and erosion eventually carry some of it to the ocean as well. The researchers used radiocarbon dating and other techniques to examine the black carbon that was buried in seafloor sediments in the Northeast Pacific that dated to about 20000 years ago.
I'm surprised that given how much black carbon is produced most of it remains in the ocean for thousands of years Coppola said.
It's very interesting that only a relatively small amount with a certain type of chemistry is removed to the ocean floor.
