Crews free humpback whale tangled in fishing line off Hawaii

February 22 at 7:23 AM

KAILUA-KONA, Hawaii — Officials say a 45-ton humpback whale entangled with fishing line in Hawaii waters for more than a week is finally free.

The Hawaiian Islands Humpback Whale National Marine Sanctuary said Saturday that its craft got within 10 feet of the mammal a day earlier and the crew used a pole equipped with a knife to saw the line free.

Ed Lyman of the sanctuary says several hundred feet of line was cut away.

West Hawaii Today reports that when the 45-foot-long whale swam free, all line but a small piece lodged in a wound was off. Lyman says that the fragment will fall away as the wound heals.

The entangled whale was first spotted Feb. 13 off the Big Island’s Kona Coast.

Experts say such entanglements could result in drowning, starvation, infections and increased susceptibility to ship strikes.

Super Pod of Gray Whales

27 January 2015

We ran an ultimate 8 hour Whale Watching trip on 1-25-15 from Dana Point to Catalina; we are Dana Wharf Whale Watching. Here’s the final sightings report from that day. There were sightings of 45 + gray whales which included a superpod of 15+ and another of 12+ (interacting with Risso’s dolphins), 1 Fin whale, 200 Offshore bottlenose dolphin, 40 Risso’s dolphin, 35 Long beaked Common dolphin, 3 Harbor Seals, dozens of CA Sea Lions and a Bald Eagle on Catalina Island. Watch all the way to the end you will see a group of Risso dolphin harassing the Gray Whales, and how they react to them. Enjoy once again, we thank all our “Whale Geek” friends and a BIG THANKS to Captain Todd Mansur and Captain Frank Brennan for flying these amazing drones.

New technology counts migrating whales by seeing the warmth of their breath

The Grey Whale migration down the west coast of America from the summer feeding grounds in the Arctic to the wintering grounds off Baja California, Mexico, is being charted in even greater detail thanks to new technology employed by scientists at the US National Oceanic and Atmospheric Administration (NOAA) just south of Monterey Bay.

Counts used to be done just by NOAA personnel using binoculars but now they are employing three thermal imaging cameras linked to a computer that is capable of analysing the images and distinguishing the whales from the heat put out by their blow as they surface to breathe.

“A whale is this great big motor that takes in a breath of air and holds it inside for a long time,” says Wayne Perryman, a NOAA Fisheries scientist who helped develop the new system. “When it exhales, the air is much warmer than the background, and we can detect that difference very easily, both day and night.”

Human observers can only work in daylight hours so in previous years the count could never be that accurate. Now the cameras work round the clock for the duration of the entire migration, so much more accurate figures can be recorded and compared year-on-year.

The thermal imaging cameras are much the same as those used by helicopter police to track criminals at night. What’s most innovative is the software that works with the cameras.

“The biggest challenge was getting the detector to be as accurate as possible without having it get fooled by false alarms,” said Dave Weller, the NOAA Fisheries scientist who leads the survey team.

The refined software the team developed can now distinguish between whales, flocks of birds and passing boats.

Not only that, but when the computer sees a blow, it can predict where and when the same whale will surface to blow again. That prediction algorithm, which is based on years of research into Gray Whale’s diving behaviour, means that the computer can track individual whales.

“If you don’t have a way of tracking who’s who, you can double-count some whales or miss them altogether,” Weller says.

“The biggest advantage of the new system is that it vastly increases our sample size. That means we can more accurately estimate the size of the population.”

Some of the thermal imaging footage can be seen here, with a passing whale being overtaken by a flock of birds and a pod of dolphins appearing in the foreground.

South Carolina waters, right whale calving habitat

Act right now! Save the North Atlantic Right Whale

7 January 2013

With fewer than 500 remaining, the North Atlantic right whale is on the brink of extinction. The biggest threat to these animals was – and still is – man. Right whale populations were depleted to near extinction by whaling and are still struggling to recover. Because right whales are coastal and spend most of their lives in waters also heavily used by humans, 72% of their known mortality is attributed to either being struck by a vessel or entangled in commercial fishing gear. But it doesn’t have to be this way! With small changes humans and whales can share these areas without continuing to push this species to extinction. …

South Carolina waters proposed as right whale calving critical habitat

Bo Petersen

Feb 17 2015 6:21 pm

Ten years after the first reports of newborn right whales off South Carolina startled observers, federal regulators propose to include waters off the coast in the “critical habitat” calving grounds for the imperiled species.

The grounds and critical area have been in southern Georgia and northern Florida, but eyewitness reports and survey flights have shown the whales calved over a wider range. The proposal was forced by a court order, after a number of conservation groups petitioned the National Oceanic and Atmospheric Administration in 2009 for the move, then sued in 2014 after delays in handling the petition.

It must move through an exhaustive review and public hearing process, but the proposal would expand the habitat from Florida and southern Georgia to southern North Carolina.

“Survey data and other studies over the past 20 years have increased our understanding of right whale ecology and habitat needs,” said Eileen Sobeck, NOAA fisheries administrator in announcing the move.

The designation would mean one more hurdle in a laborious process to win federal permits for offshore activities. It follows earlier controversial moves to protect the whales, including a 2013 NOAA requirement that makes large ships slow down in right whale waters.

Right whales are the rarest of the large whales, 40-ton creatures whose curious two-plume breathing spray and the lack of a dorsal fin distinguish them from other whales. Hunted to the brink of extinction a century ago, the critically endangered species now numbers 450 to 500 in the north Atlantic Ocean.

The whales have turned the corner toward potential recovery from a low of fewer than 300, thanks to awareness and conservation efforts. But the calving numbers have dropped in recent years, and the whales remain imperiled. Every whale alive is considered vital to the survival of the species.

Ship strikes, line entanglements and noise pollution are considered the biggest threats.

“It stops your heart for a second” to see a right whale, said Pawleys Island boater Mike Robino, who in 2005 piloted a vessel taking a state veterinarian offshore to confirm a report of a newborn calf and mom in the surf. “You realize how truly small you are compared to that animal. Having been up close and personal (to the whale), you can’t help but think if we can help them we should.”

Robino’s trip came after a sighting was made by a beach house roofer on the island. Even confirmed, the birth was considered a fluke. But survey flights begun shortly afterward found, on average, more than a dozen whales per year off South Carolina, including mothers and new calves.

The habitat proposal comes after a number of earlier protections, including a controversial rule requiring large ships to slow down near the coast when the whales are in season. The requirement was widely opposed by commercial shipping interests. The South Carolina Ports Authority helped fund survey flights out of Charleston for five years, partially to gauge the effectiveness of the rule.

“The (ports authority) will work in good faith with the U.S. Department of Commerce (NOAA and the National Marine Fisheries Service) to finalize the designation of shipping lanes developed through the evaluation of available science,” the S.C. ports agency said in reaction to the NOAA critical habitat proposal.

Survey flights ended here in 2012 due the loss of funding. They now fly the Florida-Georgia calving ground. A sighting alert network is still in place for shipping and other interests, but off South Carolina it now depends on private reports. No reports have been made this season.

NOAA did not immediately reply to questions asking what effect a critical habitat designation would have on current plans to permit sonic-boom tests and potentially drill for natural gas or oil offshore, or on military activities. Navy warfare and sonar training in the same waters recently were re-permitted without significant restrictions, despite scientific evidence the noise can deafen the whales.

The “critical habitat” proposal also would expand feeding grounds in the Gulf of Maine/Georges Bank region, according to the NOAA release.

‘Humpback whale is back in North Sea’


This video is about the young humpback whale, swimming in the Oosterschelde estuary in the Netherlands last weekend.

Translated from NOS TV in the Netherlands:

“Humpback swam back out to sea’

Yesterday, 22:09

The humpback whale seen this weekend in the Oosterschelde estuary is almost certainly back in the North Sea. Cyclists on the storm surge barrier have seen this afternoon that the animal swam out, says the foundation SOS Dolphin.

Earlier today things still looked bad for the whale. It swam in the east of the Oosterschelde and it was questionable whether it could find the “exit” again and whether it would dare. After 14:00, the animal was not seen.

But tonight, Jolanda Meerbeek of SOS Dolphin got a liberating phone call from a family who had cycled over the flood barrier. “At the first pillar they saw a meters long animal swimming out. It was in the lee of the pier and slid as it were into the sea. They also saw it exhale, a great jet emerged from the blowhole. When it was through the barrier, they saw it swim away to the north.”

Humpback whale strays into Oosterschelde estuary


This 2014 video says about itself:

During the world circumnavigation with the ‘Oosterschelde‘ we were welcomed by about 6 humpback whales who did a nice performance. This happened on the south-east side of Australia.

Unfortunately, today not so good news from the Oosterschelde estuary after which that ship was named.

This video is about a humpback whale, seen 15 February 2015 near Wemeldinge along the Oosterschelde.

Little hope for humpback in the Oosterschelde

Today, 11:41

In the Oosterschelde, near the Zeeland Bridge this weekend a young humpback whale was spotted. That had never happened before. The animal still swims around. Its survival chances are not big, says the SOS Dolphin Foundation. …

On Saturday, the first report on the humpback came, one day later the animal first appeared on images.

It is unknown how young the animal is, what is its sex, and whether it can survive independently. “It accidentally swum into the Oosterschelde, hunting for fish,” thinks Annemarie van den Berg of SOS Dolphin.

The animal swims at this time in the eastern corner of the Oosterschelde. Not a good sign. “There are just more rivers there, so it is more likely it will get stranded.”

There is still hope. “It swims properly and if the animal find its way back, it’ll be fine,” says Van den Berg. “But porpoises have previously shown that they often do not dare to get back.”

The foundation calls on people to stay away from the animal. Van den Berg: “If people are going to flock to that animal in boats, then it is in big trouble. The boats can block the way back to the North Sea. Then the probability of survival really becomes nil. In addition, the noise may cause a lot of stress and of that it has enough already.”
