Once hunted to near extinction, North Atlantic right whales are now facing new human threats that could end the species. Here are the people risking their lives to save them.Once hunted to near extinction, North Atlantic right whales are now facing new human threats that could end the species.

For whale rescuer Mackie Greene, there's no feeling in the world like seeing fishing ropes slip free of from a trapped whale. For whale rescuer Mackie Greene, there's no feeling in the world like seeing fishing ropes slip free from a trapped whale.

Three entangled North Atlantic right whales had recently been seen in the area and a rescue mission launched. Aerial surveillance had spotted one of the whales about 40 miles (65km) offshore and Greene's team headed out.Three entangled North Atlantic right whales had recently been seen in the area and a rescue mission launched.

They got close enough to the animal - which can weigh up to 70 tonnes and grow to over 55 feet, about the length of a bowling lane - to see fishing rope wrapped around the tail stock and cutting deep into its flesh.They got close enough to the animal - which can weigh up to 70 tonnes and grow to over 55 feet, about the length of a bowling lane - to see fishing rope wrapped around the tail stock and cutting deep into its flesh.
Weather had kept them off the water for part of the day, and despite the whale's distress, dusk was falling, and they had to head back to shore.Weather had kept them off the water for part of the day, and despite the whale's distress, dusk was falling, and they had to head back to shore.

After more than a week of work, the team had two small victories - they had managed to partially free two five-year-old males, one almost hogtied by fishing gear keeping it from using its tail when diving.After more than a week of work, the team had two small victories - they had managed to partially free two five-year-old males, one almost hogtied by fishing gear keeping it from using its tail when diving.

Weather in the Gulf of St Lawrence can be capricious. It's a huge body of water, and the whales spend a lot of time below the surface, making them difficult to track.Weather in the Gulf of St Lawrence can be capricious.

The work is itself dangerous - a "big game of cat and mouse", says Greene.The work is itself dangerous - a "big game of cat and mouse", says Greene.

North Atlantic right whale are like tanks in the water - heavy, wide and dense. They're also curious, acrobatic animals who can be seen breaching the water and smacking it with their flukes.North Atlantic right whale are like tanks in the water - heavy, wide and dense.

For centuries they were lucrative prey for whalers. In the medieval era, they were hunted by the Basques. Later, their blubber helped fuel the Industrial Revolution, when whale oil was used to lubricate factory machinery.For centuries they were lucrative prey for whalers.

Now their habitat overlaps with a heavily industrialised part of the ocean ranging from Florida to Newfoundland. It's over 1,000 miles of coastline crowded with ship traffic and economically important commercial fisheries.Now their habitat overlaps with a heavily industrialised part of the ocean ranging from Florida to Newfoundland.

Researchers documented the case of one female right whale, healed from propeller wounds she received as a calf, who is believed to have died from an infection when she became pregnant 14 years later and her old scars split as she grew.Researchers documented the case of one female right whale, healed from propeller wounds she received as a calf, who is believed to have died from an infection when she became pregnant 14 years later and her old scars split as she grew.
Entanglements can cause a slow partial amputations or mutilations, and whales who can't free themselves from the ropes can drag heavy gear for months. They may eventually drown or starve.Entanglements can cause a slow partial amputations or mutilations, and whales who can't free themselves from the ropes can drag heavy gear for months.

In 2003, Greene's colleague, scientist Moira Brown, in collaboration with the shipping industry and the Canadian government, had shipping lanes rerouted around a significant feeding ground and nursery habitat area in the bay - the first time ever international shipping lanes were moved to help a species.In 2003, Greene's colleague, scientist Moira Brown, in collaboration with the shipping industry and the Canadian government, had shipping lanes rerouted around a significant feeding ground and nursery habitat area in the bay - the first time ever international shipping lanes were moved to help a species.

This June, six right whales were killed, devastating the network of scientists and conservationists fighting to save the animals from extinction.

It's unlikely they are the only mortalities, says Cathy Merriman a biologist with Canada's federal fisheries department.It's unlikely they are the only mortalities, says Cathy Merriman a biologist with Canada's federal fisheries department.

It's believed the whales are following copepods—tiny crustaceans that form the base of their diet - as their distribution shifts due to climate change. Right whales have also been having fewer calves, which could be linked to them not getting enough food.It's believed the whales are following copepods—tiny crustaceans that form the base of their diet - as their distribution shifts due to climate change.

In August of that year, after over nine whale deaths, the government brought in some measures, including large vessel speed restrictions, in parts of the Gulf. It has continued since to slow boats and close some fishing areas to make way for whales.In August of that year, after over nine whale deaths, the government brought in some measures, including large vessel speed restrictions, in parts of the Gulf.

Greene was able to replace the old government surplus boat the Campobello team had been using for rescues since 2002 - a C$300,000 ($230,000;£184,000) upgrade.Greene was able to replace the old government surplus boat the Campobello team had been using for rescues since 2002 - a C$300,000 ($230,000;£184,000) upgrade.
"We've been asking for this for years, decades, probably, about how we increase this response capacity - for all elements of response - and it's been tricky, until we had a disaster strike" says Wimmer."We've been asking for this for years, decades, probably, about how we increase this response capacity - for all elements of response - and it's been tricky, until we had a disaster strike" says Wimmer.

That tech, which would secure fishing rope to the bottom of the ocean until it needs to be released, could be hugely beneficial but is years away. It's still too finicky and expensive to be used widely or reliably.That tech, which would secure fishing rope to the bottom of the ocean until it needs to be released, could be hugely beneficial but is years away.

Other possibilities are "weak" ropes that could break under a certain amount of pressure, making it easier for a whale to free itself, or using underwater microphones to improve whale tracking.Other possibilities are "weak" ropes that could break under a certain amount of pressure, making it easier for a whale to free itself, or using underwater microphones to improve whale tracking.

Slowing ships is still the best option to avoid fatal strikes - limited experiments to warn right whales of nearby vessels have been unsuccessful and it may be hard for them to hear approaching ships - but better early detection of whales ahead could help navigators.Slowing ships is still the best option to avoid fatal strikes - limited experiments to warn right whales of nearby vessels have been unsuccessful and it may be hard for them to hear approaching ships - but better early detection of whales ahead could help navigators.
Brillant says the government has made "difficult and unpopular decisions" in closing down large areas to commercial fishing and slowing shipping traffic - disruptions to important industries.Brillant says the government has made "difficult and unpopular decisions" in closing down large areas to commercial fishing and slowing shipping traffic - disruptions to important industries.
