Safe Habitat For North Atlantic Right Whales Will Expand

January 28, 2016 By Marlene R. Litten

"atlantic right whale"

After one year of waiting, it was decided that the safe habitat for North Atlantic right whales will expand in order to assure the survival of the endangered species. The expanded habitat was taken under consideration by the National Oceanic and Atmospheric Administration (NOAA) and the decision was taken as of January 27th, 2016.

The critically endangered whales will benefit from a major widening of their protected areas, to live, feed, breed, and raise their young.

Back in 1994, officials called for the protection of the North Atlantic right whales after their numbers were brought down to a worrying 300 left. This was due mainly to commercial fishing, and the unfortunate habits of the marine mammals themselves. Right whales are very docile, slow swimmers who have a habit of travelling near the coasts and close to the surface of the water. That made them especially vulnerable to whalers.

Over time, their population diminished, so NOAA’s National Marine Fisheries Service designated their first protected habitat. They were offered an area of almost 3,000 square nautical miles, including a portion of Cape Cod Bay, Stellwagen Bank, the Great South Channel, coastal Georgia and the eastern shoreline of Florida.

Only 520 right whales alive today

However, today’s human activities and highly industrialized coastlines have hindered the species’ recovery. Be it ship strikes or entanglements with fishing gear, the right whales have not seen as big of an improvement as hoped. In fact, the numbers round up at just 520 right whales around the waters after more than twenty years worth of efforts and protection under the Endangered Species Act (ESA). Thus, the call has been made for an expansion of their protected areas, one that was recently approved.

From 3,000 nautical mi2 to 21,000 nautical mi2

NOAA officially announced that the critical habitat for the North Atlantic right whales will be expanded to over 21,000 square nautical miles. The new area will include regions in the Gulf of Maine up to the Canadian border. According to Eileen Sobeck from NOAA’s National Marine Fisheries Service, they have had two decades worth of information since the first habitat was set. Now, they have a better understanding of the species and believe that an expansion is required for their survival.

Sobeck claimed that they have indeed made progress. The species are seeing a very slow recovery, but there is need for additional effort to ensure their survival. They “have a long way to get to complete recovery”.

As stated by Charles “Stormy” Mayo from the Center for Coastal Studies, it’s difficult to put an animal in one tiny box. They don’t stay in one place, and whales in particular are known to travel thousands of miles in just one year of their life. The adjustment properly recognizes their needs and their wide use of their environment.

However, NOAA underlines the fact that the newly designated area will not truly affect future offshore projects. But, they will certainly go under more scrutiny, and it will allow government officials to get involved in mitigating future impacts with the endangered species. Should something go wrong, officials will be in their right to act on the side of the whales.

The decision will go into effect at the end of next month, but current operations will not be impacted by the change. It’s not a refuge for the North Atlantic right whales, but merely an area where their survival can be aided in case of trouble.

A New Hope Emerges For Killer Whales

January 7, 2015 By Denise Ehrlich

A-New-Hope-for-Killer-Whales-Endangered-Species

New hope for killer whales arises as an infant orca was seen in the Pacific Ocean’s bay known as Puget Sound on the 30th December. This strange finding was made by one of the Center for Whale Researches top researchers, Dr. Ken Balcomb. Presently the newborn orca swims off the shore of Washington state. Thought to be older than a week now, this infant is a new hope in over 2-years. Sightings like this are uncommon. As per NOAA (National Oceanic and Atmospheric Administration), around 35% to 45% of infant orcas lose their life before the age of one.

In the start of December J-32, a 19-year-old pregnant female whale, died around the Strait of Georgia. Researchers, including Ken Balcomb, drew her on shore. A necropsy on J-32 was conducted. The results demonstrated that the whale had miscarried. This set off a bacterial contamination which brought about the passing of J-32. Wild life researcher Brad Hanson with the NOAA said that “We lost lots of reproductive potential,” and “The loss of J-32 was an alarming setback.”

The name of the infant orca is J-50 and its mom is not known. Ken Balcomb said that two possible nominees are J-16 and J-36. J-16 is a 43-year-old female. She had three calves that survived and J-50 can be her calf. J-36 is the other contender for being the mother of J-50. She is a juvenile female and this could be one of her first calves. J-50’s dorsal fin and back have signs that researcher said it could propose an amazing reality: its delivery was helped by another whale. J-50 is likewise the 78th orca of the populace on the shoreline of Washington state and Canada.

Killer whale groups are recognized all over the globe. In the United States and Canada this particular group of killer whales is seen as a threatened species. As per Brad Hanson, a wildlife scientist with the National Oceanic and Atmospheric Administration, a critical part of the issue that prompted this result for the killer whale group is the taken for hostage showcase amid the late 1960s and early 1970s.

Over a large portion of the populace (around 40 killer whales) was taken from their natural habitat. In the 1990s the populace expanded to nearly 100 whales. A turn down of 20% was enlisted in the early 2000s. United States acted by marked the group as threatened in 2005.

New Coral Species Discovered in Californian Coast

November 7, 2014 By Denise Ehrlich

Recently, researchers and NOAA (National Oceanic and Atmospheric Administration) discovered a new species of deep-sea coral off the Northern California coast.

On Wednesday, NOAA announced that a research team using small submersibles discovered the coral near national marine sanctuaries off the coast of Sonoma County in September.

The coral (genus Leptogorgia) was found about 600 feet deep in underwater canyons close to the Gulf of Farallones and Cordell Bank national marine sanctuaries.

“Studying these life forms helps determine the ecological importance of deep sea communities and the threats they face,” Farallones sanctuary’s manager said.

The scientists revealed that during research we also found a “highly unusual” nursery area for catsharks and skates.

Drone Captured Marvelous Footage of Orca Whales

October 19, 2014 By June Harris

Drone-captured-Orca-whales-images-Video

Thanks to the NOAA’s Fisheries and the Vancouver Aquarium researchers who captured the stunning images and video of Orca whales who were swimming and playing. The researchers have also witnessed the death of two orca whales in the region.

NOAA (National Oceanic and Atmospheric Administration) is the government agency, which studies the conditions of the atmosphere and oceans told, “researchers has used a drone to study orca whales in the region”. In the entire history, it was the first time when researchers flew a drone (custom-built hexacopter) in order to study orcas. A high-resolution camera was fitted inside the drone in order to capture images and video of the species of whale. The drone flew into the region of Johnstone Strait off British Columbia.

The researchers had kept the hexacopter at a distance of 100 feet from the orcas, so that it would not agitate the orcas, still the camera photographed detailed images of the killer orca whales. The researchers believed that these images would eventually help them in better understanding the behavior and health of the whales.

The images and video captured by the hexacopter, would not just provide the glance of orca’s life, but these will also help us in order to know whether the killer whales are doing well or whether they are getting sufficient food, researchers stated.

The orca whales depend on Chinook Salmon, endangered species, for their food and the deficiency of Chinook Salmon could affect the population of the orca whales. While observing, we found that an orca whale was in a poor condition and went under the water and never resurfaced. The researchers believed that the orca whale was dead.

Lance Barrett-Lennard, lead researcher of Vancouver Aquarium’s Marine Mammal Research Program, stated that, “Another orca’s death is still a mystery for researchers. It has not been determined yet if it was sick or injured.”
