New Online Tool Launched to Track Ship Speeds in Areas Frequented by Right Whales

July 22, 2020 — Oceana has released a new online tool that allows anyone to track ship speeds in speed zones designed to protect North Atlantic Right Whales along the east coast of the U.S. and Canada.

Using Global Fishing Watch data, which is a component of the new tool called Ship Speed Watch, Oceana Canada tracked ship speeds in the Cabot Strait from April 28 to June 15, 2020.

During the 49-day period, Transport Canada asked vessels longer than 13 meters to slow down to 10 knots.

Only a few complied, with 67 percent of the ships (464 out of 697) traveling faster than the 10-knot limit, and some traveling 20 knots or faster.

Whales Get A Break As Pandemic Creates Quieter Oceans

July 21, 2020 — When humpback whales migrated to Glacier Bay in Alaska this year to spend the long summer days feeding, they arrived to something unusual: quieter waters.

As the COVID-19 pandemic slows international shipping and keeps cruise ships docked, scientists are finding measurably less noise in the ocean. That could provide momentary relief for whales and other marine mammals that are highly sensitive to noise.

Through networks of underwater hydrophones, scientists are hoping to learn how the mammals’ communication changes when the drone of ships is turned down, potentially informing new policies to protect them.

“More needs to be done,” says Jason Gedamke, who manages the ocean acoustics program at NOAA Fisheries. “When you have animals that for millions of years have been able to communicate over vast distances in the ocean, and then once we introduce noise and have increased sound levels and they can’t communicate over those distances, clearly there’s going to be some impact there.”

Baleen Whales Have Changed Their Distribution in the Western North Atlantic

July 17, 2020 — The following was released by NOAA Fisheries:

Researchers have been using passive acoustic recordings of whale calls to track their movements. They have found that four of the six baleen whale species found in the western North Atlantic Ocean — humpback, sei, fin and blue whales — have changed their distribution patterns in the past decade. The recordings were made over 10 years by devices moored to the seafloor at nearly 300 locations from the Caribbean Sea to western Greenland.

“All four whale species were present in waters from the southeast U.S. to Greenland, with humpbacks also present in the Caribbean Sea,” said Genevieve Davis, a senior acoustician at the Northeast Fisheries Science Center in Woods Hole, Massachusetts and lead author of the study. “These four species were detected throughout all the regions in the winter, suggesting that baleen whales are widely distributed during these months. Humpback, sei, fin, and blue whales also showed significant changes in where they were detected between the two time periods considered in this study: before and after 2010.”

A large group of federal, state and academic researchers from the United States and Canada conducted the study, published in Global Change Biology. It is the first to show the occurrence of these four species across the western North Atlantic Ocean over long time spans and at a large spatial scale. The study also demonstrates how whale distributions have changed over time, and in particular since 2010.

New technology promises to save the whales by reducing the need for crab fishing lines.

July 16, 2020 — After a slightly better year in 2017, the number of whales getting entangled in fishing gear has gone back up, according to a new report from the National Marine Fisheries Service. Researchers confirmed 105 whale entanglements nationwide in 2018, the latest year for which data is available, noting the number is “much higher” than average.

These findings come as a possible solution emerges out of a collaboration being led by Monterey Bay conservationists, fishermen and fishing gear designers.

On the Pacific coast, whales pass through stretches of ocean that are important for Dungeness crab fishing and they sometimes get caught in lines connecting traps on the ocean floor to buoys at the surface. Technology that is under development would all but eliminate vertical lines and buoys. Using ropeless or pop-up innovations, these new crab traps would sit idly on the ocean floor until receiving an acoustic signal from the fisherman. Only then would the trap release a rope and buoy to the surface.

“We are working with fishermen to see what works and what doesn’t and what allows the fisherman to survive economically,” says Geoff Shester, a Monterey-based scientist with nonprofit Oceana. “The Monterey Bay is the epicenter of the whale entanglement issue.”

Stanford lab develops high-tech tools to study whales in the wild

July 15, 2020 — Scanning the airwaves over Monterey Bay with a hand-held antenna, Stanford University researchers listen for blue whales – or, more precisely, they listen for the suction tags they’ve stuck on blue whales. The first beep sounds and the captain whips the boat on course, following the quickening signal to find the surfacing giant. The three-person crew must reach the animal before it disappears under the ocean, hidden from sight, radar and study for another 10 minutes. [Note: This research was conducted prior to the novel coronavirus pandemic, and has been on hold in accordance with current guidance regarding research operations.]

The crew in this fast-paced chase hails from the lab of Jeremy Goldbogen, assistant professor of biology in the School of Humanities and Sciences at Stanford’s Hopkins Marine Station. In the Monterey Bay and around the world, Goldbogen and his team employ drones, sound-based mapping equipment, and sensor-packed tags to demystify the lives and biology of rorqual whales – large whales that feed by lunging at groups of prey and filtering water through baleen plates. These include humpback, minke, fin and of course blue whales, which at nearly 100-feet long are the largest creatures known to have ever lived.

“The largest animals of all time can’t be in a laboratory in a building, so we’ve been developing technology that pushes the envelope in terms of understanding how animals operate in the open ocean,” said Goldbogen.

The International Union for Conservation of Nature Updates Classification of the North Atlantic Right Whales from Endangered to Critically Endangered

July 10, 2020 — The following was released by NOAA Fisheries:

The International Union for Conservation of Nature recently changed its Red List Category for North Atlantic right whales from Endangered to Critically Endangered. The criteria used to evaluate this change are outlined in the IUCN Red List Categories and Criteria, Section V. Within the United States, North Atlantic right whales are already in the highest risk category possible under both the Marine Mammal Protection Act (Strategic and Depleted) and Endangered Species Act (Endangered).

In 2019, NOAA Fisheries also added North Atlantic right whales to our Species in the Spotlight initiative, which focuses resources on the most imperiled endangered species under NOAA Fisheries’ jurisdiction. While IUCN Red List categories have no direct relationship to categorizations under the MMPA or ESA, NOAA Fisheries shares the IUCN’s concern for North Atlantic right whales. We continue to use our authority under the MMPA and ESA to protect and recover the species.

International conservation group designates right whales as critically endangered

July 10, 2020 — In a move that puts pressure on federal officials to do more to protect the species, the International Union for Conservation of Nature on Thursday designated North Atlantic right whales as “critically endangered” on its Red List of Threatened Species, the last classification before they’re considered extinct or “gone from the wild.”

The updated status highlights the need to protect a species that is believed to have fewer than 400 animals left, with only about 85 reproductive females, environmental advocates said. The IUCN, a leading global conservation organization, found their population declined by 15 percent between 2011 and 2018 and estimated there are only about 250 mature whales left.

“The dramatic declines of species such as the North Atlantic right whale … highlight the gravity of the extinction crisis,” Jane Smart, global director of IUCN’s biodiversity conservation group, said in a statement. “The world needs to act fast to halt species’ population declines and prevent human-driven extinctions.”

North Atlantic right whale gains official “critically endangered” classification by IUCN

July 9, 2020 — The International Union for Conservation of Nature’s recent Red List publication has indicated that the North Atlantic right whale is now officially classified as “critically endangered.”

The classification is reserved for animals that are on the brink of extinction in the wild. Currently, its estimated that only 400 right whales remain, and of those, only one-quarter are reproductive-aged females capable of producing more calves.

Attention Crabbers: Whales spotted off Oregon Coast

July 8, 2020 — The following was released by the West Coast Seafood Processors Association:

Due to recent sightings of humpback whale aggregations on the inshore whale survey transects between Newport and North Bend and fishermen’s reports of humpbacks in the 25- to 50-fathom area between Seal Rock and Coos Bay, the Oregon Department of Fish and Wildlife is recommending all gear be moved to shallower water, preferably inside 25 fathoms.

Already, Oregon crab gear from this year’s fishing season was found in June on a dead juvenile humpback whale off of Point Reyes, Calif.

It is in the industry’s best interest to avoid whale entanglements.

Fishermen should also observe best practices to avoid whales, especially during these months of higher ESA-listed humpback and blue whales off Oregon. Those best practices include:

  • Removing fishing gear not actively tended;
  • Use the minimum amount of scope necessary to compensate for tides, currents and weather;
  • Remove excess lines floating at the surface;
  • Maintain gear to ensure lines and buoys are in good working condition and clearly marked;
  • Remove all crab pots from the ocean by August 14;
  • Bring derelict gear to shore in-season; and
  • Consider participating in the post-season derelict gear program.
