Q: Image copyright Greenpeace Image caption The reef runs from French Guyana to the Brazilian state of Maranhao 
  
 The first pictures of a huge coral reef system discovered in the Amazon last year have been released by environmental campaigners. 
  
 The Amazon Reef is a 9,500 sq km (3,600 sq miles) system of corals, sponges and rhodoliths, Greenpeace says. 
  
 The reef is almost 1,000 km (620 miles) long, and is located where the Amazon River meets the Atlantic Ocean. 
  
 Oil drilling could start in the area if companies obtain permits from the Brazilian government, the group warns.

 "This reef system is important for many reasons, including the fact that it has unique characteristics regarding use and availability of light, and physicochemical water conditions," researcher Nils Asp, from the Federal University of Para, said in a statement. 
  
 "It has a huge potential for new species, and it is also important for the economic well-being of fishing communities along the Amazonian coastal zone."

 Scientists were surprised by the discovery, in April 2016, as they thought it was unlikely that reefs would be found it the area given unfavourable conditions," they said in a paper in the scientific journal Science Advances. 
  
 The reef ranges from about 25-120m deep (82-393ft)

 Mr Asp now says that his team wants to gradually map the system. At the moment, only 5% of it has been mapped. 
  
 "Our team wants to have a better understanding of how this ecosystem works, including important questions like its photosynthesis mechanisms with very limited light."

 But Greenpeace says drilling in the area means a "constant risk of an oil spill". 
  
 Campaigner Thiago Almeida said environmental licensing processes for oil exploration there are already under way. 
  
 "The Cape Orange National Park, the northernmost point of the Brazilian state of Amapa, is home to the world's largest continuous mangrove ecosystem and there is no technology capable of cleaning up oil in a place of its characteristics," the group said. 
  
 "In addition, the risks in this area are increased due to the strong currents and sediment that the Amazon River carries."

 The group said that, so far, 95 wells have been drilled in the region, and 27 of them were abandoned as a result of mechanical incidents - the rest due to the absence of economically or technically viable gas and oil. ||||| The discovery of the 600 mile-long reef in 2016 stunned scientists but oil companies are planning to drill in the area 
  
 The first images have been released of a unique coral reef that stunned scientists when discovered in 2016 at the mouth of the Amazon. 
  
  
  
 The 600 mile-long reef is expected to reveal new species as scientists explore it further, but oil companies are planning to drill in the area. The photographs were captured from a submarine launched to a depth of 220 metres from the Greenpeace ship Esperanza. Campaigners say drilling must be prevented to protect the reef.

 The discovery of the reef, which stretches from French Guiana to Brazil’s Maranhão state, was a complete surprise to scientists because many of the world’s great rivers have major gaps in reef systems at their mouths. Corals mostly thrive in clear, sunlit water, and the waters near the mouth of the Amazon are some of the muddiest in the world. 
  
 But the reef spans the mouth of the Amazon and is already known to be home to more than 60 species of sponges, 73 species of fish, spiny lobsters and stars. 
  
 “This reef system is important for many reasons, including the fact that it has unique characteristics regarding use and availability of light,” said Nils Asp, a researcher at the Federal University of Pará in Belém, Brazil, on board the Esperanza. “It has a huge potential for new species, and it is also important for the economic well-being of fishing communities along the Amazonian coastal zone.” 
  
 Oil exploration blocks have been granted for the area and the oil companies Total, BP and Petrobras could start drilling if they obtain authorisation from the Brazilian government. 
  
 “We must defend the reef and the entire region at the mouth of the Amazon river basin from the corporate greed that puts profits ahead of the environment,” said Thiago Almeida, a campaigner at Greenpeace Brazil. The mouth of the Amazon river basin is also the habitat of the American manatee, the Amazon river’s yellow turtle, dolphins and the river otter.

 Scientists revealed the existence of the reef in April 2016 and wrote: “These [exploration] blocks will soon be producing oil in close proximity to the reefs, but the environmental baseline compiled by the companies and the Brazilian government is still incipient and largely based on sparse museum specimens. Such large-scale industrial activities present a major environmental challenge.” 
  
 Greenpeace Brazil said 95 wells have already been drilled in the region, none of which found economically or technically viable gas and oil. But the Brazilian government speculates that the area may contain 14bn barrels of oil. |||||
A:
Last year, scientists made an amazing discovery under the mud and muck at the mouth of the Amazon River: a long-rumored 600-mile-long coral reef. Now the first images of the natural phenomenon are emerging, captured from a sub sent 720 feet down into the murky waters off a Greenpeace boat, the Guardian reports. The reef stretches from French Guiana to the Brazilian state of Maranhao, per a Greenpeace press release, and is astonishing researchers for its ability to flourish in dark waters. The Guardian notes corals tend to flourish in clear, sun-penetrating waters. That makes "this reef system important for ... the fact that it has unique characteristics regarding use and availability of light," a Federal University of Para researcher says, adding that the reef also holds "huge potential for new species." But just as scientists have started to study the reef, oil companies have started to move in—and if Brazil's government OKs the permits they're seeking, these companies (including Petrobras, BP, and Total) will be able to start drilling in the area, the BBC reports. With drilling comes the risk of spills, and Greenpeace warns that some ecosystems such as the mangroves in Cabo Orange National Park won't be able to receive proper cleanup if oil does leak out. A Greenpeace Brazil activist reiterates the call to defend the reef, as well as the entire region, "from the corporate greed that puts profits ahead of the environment. One of Total's oil blocks is only [5 miles] from the reef, and environmental licensing processes are already under way." (The Great Barrier Reef lost nearly a quarter of its coral last year.)
