on the west coast, shellfish farmers have been dealing with ocean acidification since the mid-2000's. dr. richard feeley is the researcher who first identified ocean acidification as the cause for oyster spat failures in the northwest back in 2005. he noted in a recent npr article that the acidification problem is only going to get worse. quote, the acidified water welling up in the ocean floor now contains carbon dioxide gas emitted 50 years ago, he explained. carbon emissions are worse since then. some hatcheries in the northwest are already moving operations to less acidic waters off hawaii, and others are looking to buffer the water with sea grasses to absorb carbon and lower acidity. shellfish farmers in rhode island are facing the challenge of acidifying waters as well. at the same time, marine species are facing deoxygenation, increased harmful algae, and other consequences of a warming and acidifying ocean. the symptoms of climate change in the ocean are everywhere. a recent study in global change biology warned reduced oxygen availability could limit the growth of fish and other species. well, fishermen can't ma

of the world's oceans have been explored their home to a vast range of creatures from delicate jellyfish to terrifying predators. off the coast of north western africa a team of researchers has discovered a gigantic structure on the sea bed built by corals. this amazing underwater landscape is being researched by a team from the university of braman a reef four hundred kilometers long and up to one hundred meters tall. it was created here in the atlantic off the coast of mauritania in west africa by cold water corals. silly minutes they live in great depth in absolute darkness they rely on currents to deliver tiny particles of food for them to. often when those particles are plankton which drift like snowflakes through the oceans the supply at those depths is meager so cold water corals grow slowly not more than fifteen metres in a thousand years. still the team have discovered astonishing coral formations. harm sions aphelion found very many reefs especially in the atlantic with coral mounds some more than three hundred meters tall. and that's as tall as the eiffel tower all the t.v. tower in berlin that's really big. absolut course a he will leave it in to find out mor

west coast of north america researchers have noticed that the return of top level predators is having an impact on restoring all kinds of underwater life and the entire ocean system. what the sea otters do it's kind of it turns the tables against. groupings of facts of sea otters eating crabs especially the seen grass an advantage again so if we introduce top predators like sea otters to ecosystems around the world will it have a knock on effect potentially in the prediction is yes so if you re store food webs which means a lot of times bringing back a top predator to a system that we wiped out they have a great potential for restoring the health of that system. the most memorable moments with al jazeera was when i was on air as hosni mubarak fell with the crowd to tahrir square to appear. as. if something happens anywhere in the world how does iraq is in place we're able to cover news like you know all the news organizations. were able to do it properly. that is all straight. houses are for me is different because there's a maturity about its views god in the room is really genuine the other forces child but the feds take the risk of a story like you'll.

researchers were working in the chagos islands, an archipelago of about 60 islands in the indian ocean these islands have been visited by ships which brought rats that invaded these tiny island spaces and started to pray on sea birds, eating their eggs and eating the nestlings. so i learnt that have rats have basically very few to no sea birds and there are some islands that are rent—free. this team could compare and contrast and what they found is essentially that the rats just decimate the sea bird population and the reason that damages coral reefs is because when sea birds go out and forage in these very nutrient rich areas and they come back and they put their droppings all over the island, they basically come back and fertilise the island with his natural fertiliser. and that drifts into this marine environment and into the coral reef and it fertilises the coral reef. so what they found is the algae that grows on the coral reef contains some of the nitrogen that is actually in these bird droppings so they can actually trace it back to the birds and say yes, they are fertilising th

researchers say that makes them the oldest colors in the geological record. they say analysis of the discovery confirms that microscopic bacteria dominated the ocean's food chain long before animals came along.
