NOAA announces higher-than-forecasted Gulf of Mexico “dead zone”

August 5, 2021 — NOAA announced on Tuesday, 3 August that its scientists have determined the size of this year’s “dead zone” in the Gulf of Mexico to be more than 6,300 square miles, a figure that’s both above the recent average and well above what officials initially forecasted in June.

The “dead zone” is term applied to the hypoxic zone that is annually established in the Gulf of Mexico. Fed by agricultural runoff, the Mississippi River dumps nutrient-rich water into the gulf, leading to algae growth during the spring and summer months. As that dies and sinks to the bottom, bacteria decay the algae but also consume oxygen in the process, resulting in an area of the ocean that is considered unsustainable for marine life.

Connecticut official says “menhaden are most abundant fish in the sea”

August 4, 2021 — It’s the time of year when fish abound in the region’s rivers, lakes and Long Island Sound, and also a time when some fish are dying.

While it’s an annual event, die-offs of menhaden, or bunkers, is most likely larger this year because of all the rain the state had in July, according to David Molnar, senior marine fisheries biologist with the state Department of Energy and Environmental Protection.

Another factor is that because of fish management, “menhaden are at an all-time high abundance. They are the most abundant fish in the sea,” he said.

Bunker serve as food for larger fish, ospreys and whales, as well as fertilizers, animal feed and bait for crab and lobster, according to the National Oceanic and Atmospheric Administration.

They are saltwater fish but all the rain has reduced the salinity in the rivers, Molnar said. “Typically, the saltwater wedge in the Connecticut River can go all the way to Haddam,” he said. Now, it’s fresh water all the way to the breakwater.

At Shoreline towns such as Lyme, “as far as you can see are schools of menhaden,” Molnar said. “It’s an amazing sight. There are thousands and thousands of them.”

But in Guilford, for example, the problem in the West River, which Molnar called “a beautiful system, good water quality,” is that too many fish crowd in, creating school-induced hypoxia. “As the water temperature increases, they consume all the oxygen” and become stressed. Then, “diseases and parasites that they harbor” are able to flourish, killing even more fish.

Molnar said the bunker have been swimming in the West River since May, but the heavy rains in July brought too much fresh water, pushing the salt water out. “This is the third-wettest July in 100 years. That’s a lot of water,” Molnar said.

Monterey Bay and parts of Big Sur added to expanded killer whale protection

August 4, 2021 — The federal government Monday expanded its critical habitat area for the endangered southern killer whale population that now includes all of Monterey Bay and a portion of the waters off the Big Sur coast.

The new critical habitat designation also added a large portion of the Monterey Bay National Marine Sanctuary down to Point Sur, about 25 miles south of Monterey. The new designation takes effect on Sept. 1.

The demise of what the National Oceanic and Atmospheric Administration, or NOAA, calls the Southern Resident population of killer whales is the result of a number of factors, including the lack of its primary food source: chinook salmon

Higher Vessel Speeds Offset Salmon Abundance for Endangered Orcas, Reducing Chance of Catching Prey

August 4, 2021 — The following was released by NOAA Fisheries:

Increased abundance of salmon in the inland waters of the Salish Sea increased the odds of endangered Southern Resident killer whales capturing salmon as prey, but increased speeds of nearby boats did just the opposite, according to new research findings.

The research was led by NOAA Fisheries’ Northwest Fisheries Science Center. It found that the orcas descended more slowly, and took longer dives to capture prey, when nearby boats had navigational sonar switched on. The sonar from private and commercial vessels directly overlaps the main sound frequencies the whales use to hunt. This may mask the whales’ signals and force them to expend more energy to catch prey.

“That suggests that it may prolong their effort to dive in search of prey, which like all marine mammals they have to do on a breath hold—so they can stay underwater only so long,” said Marla Holt, research wildlife biologist at the Northwest Fisheries Science Center and lead author of the new research. Researchers used suction-cup tags that record whale movements and sound to track and analyze their behavior and use of sound to hunt.

Earlier research found that the faster nearby vessels traveled, the greater noise the endangered killer whales experienced. That could help explain why higher speeds of nearby vessels were associated with reduced odds of the whales capturing prey. Faster vessels might also seem more unpredictable to the whales, possibly distracting them as they close in on prey, Holt said.

“Consequences of reduced food intake include negative impacts on the whales’ ability to meet their energetic requirements to support key life functions, including growth and reproduction,” the scientists wrote in the new research paper published in the journal Marine Environmental Research.

Gulf of Mexico ‘dead zone’ larger than normal, NOAA says

August 4, 2021 — The National Oceanic and Atmospheric Administration (NOAA) is warning that the Gulf of Mexico’s “dead zone” is larger than average, with about 4 million acres of water potentially uninhabitable to fish and other marine life.

The agency said in a Tuesday report that for the past five years, the average hypoxic zone, or area with little to no oxygen where marine life easily dies, has been 5,380 square miles.

In 2021, this area is about 6,334 square miles, about 2.8 times larger than the 2035 target set by the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force, better known as the Hypoxia Task Force.

New ‘slow zone’ to protect rare whales off Massachusetts

August 4, 2021 — The federal government has announced a new voluntary speed restriction zone to try to protect rare whales off the Massachusetts coast.

The National Oceanic and Atmospheric Administration said the new “slow zone” is located southeast of Nantucket and began on Aug. 1. It’s in effect through Aug. 16.

The zone is designed to protect North Atlantic right whales, which number only about 360.

The agency is asking mariners to route around the area entirely or transit through it at 10 knots (11.5 miles per hour) or less.

Give Right Whales Room

North Atlantic right whales are on the move along the Atlantic coast of the U.S. NOAA is cautioning boaters and fishermen to give these endangered whales plenty of room. We are also asking all fishermen to be vigilant when maneuvering to avoid accidental collisions with whales and remove unused gear from the ocean to help avoid entanglements. Commercial fishermen should use vertical lines with required markings, weak links, and breaking strengths.

Right Whales in Trouble

North Atlantic right whales are protected under the U.S. Endangered Species Act and the Marine Mammal Protection Act. Scientists estimate there are only about 400 remaining, making them one of the rarest marine mammals in the world.

North Atlantic right whales are NOAA Fisheries’ newest Species in the Spotlight. This initiative is a concerted, agency-wide effort to spotlight and save marine species that are among the most at risk of extinction in the near future. 

In August 2017, NOAA Fisheries declared the increase in right whale mortalities an “Unusual Mortality Event,” which helps the agency direct additional scientific and financial resources to investigating, understanding, and reducing the mortalities in partnership with the Marine Mammal Stranding Network, Canada’s Department of Fisheries and Oceans, and outside experts from the scientific research community.

A Research Vessel Found SpongeBob Look-Alikes A Mile Under The Ocean’s Surface

August 2, 2021 — An ocean expedition exploring more than a mile under the surface of the Atlantic captured a startlingly silly sight this week: a sponge that looked very much like SpongeBob SquarePants.

And right next to it, a pink sea star — a doppelganger for Patrick, SpongeBob’s dim-witted best friend.

Christopher Mah was one of the scientists watching a live feed from a submersible launched off the NOAA ship Okeanos Explorer. He’s a research associate at the National Museum of Natural History who frequently collaborates with National Oceanic and Atmospheric Administration. He’s also an expert on starfish.

Mah immediately noticed the underwater creatures’ resemblance to the animated buddies. “They’re just a dead ringer for the cartoon characters,” Mah tells NPR.

So he tweeted an image of the two noting the resemblance, delighting lots of folks. Someone helpfully added faces and legs.

Expanded Critical Habitat Signals Much of West Coast Contributes to Recovery of Endangered Killer Whales

August 2, 2021 — The following was released by NOAA Fisheries:

Today we announced that we are expanding designated critical habitat for endangered Southern Resident killer whales. They will now include most coastal waters from Washington to Monterey Bay in California—formerly they encompassed only most of the inland waters of Washington. This designation encompasses waters where we now know that the Southern Residents hunt for salmon from West Coast Rivers and other marine species.

We appreciate the nearly 2,000 comments on our proposal to expand the designated critical habitat. The Endangered Species Act defines critical habitat as areas with “physical or biological features essential to conservation of the species” that may need special protection.

While the expansion of critical habitat recognizes that the whales forage across much of the West Coast, it is unlikely to extensively affect coastal activities, such as fishing. That is because NOAA Fisheries and the Pacific Fishery Management Council, which provides recommendations to NOAA Fisheries on fishing seasons and regulations, already consider killer whales and Chinook salmon when setting salmon harvest quotas. NOAA Fisheries is currently taking comments on a proposal from the Council to limit commercial and recreational fishing in certain areas as far south as Monterey Bay in California in years when salmon returns are expected to be low.

NOAA Fisheries completed a biological opinion on the operation of dams on the Columbia and Snake River in 2020. It considered the potential impacts on Southern Residents and their prey since they have long been known to feed on Columbia and Snake River salmon. The opinion found that hatchery salmon more than make up for any reduction in salmon numbers related to the operation of the dams.

Recent research based on the DNA signatures of West Coast salmon stocks showed that killer whales prey on salmon from a diversity of West Coast Rivers. They span as far south as the Sacramento River and north to Canada and Alaska. Recovery actions for killer whales include:

  • Release of additional hatchery fish to supplement their prey
  • Extensive habitat restoration to improve natural production of salmon in the longer term

The designation of critical habitat provides an extra layer of protection when a federal agency takes an action that could impact the critical habitat of the whales. It also sends the message that everyone on the West Coast has a role to play in supporting the whales’ recovery.

“While the Southern Residents may be best known in the Pacific Northwest, the whole West Coast can contribute to recovery of the whales and the salmon that they rely on,” said Lynne Barre, recovery coordinator for the Southern Residents. “Regardless of where they are foraging, they feed on a mix of salmon from different West Coast rivers. That means the way we all use water, the way we protect habitat, how we handle our storm runoff—it all makes a difference.”

The newly designated critical habitat includes coastal waters from 6.1 to 200 meters deep with three essential physical and biological features:

  • Water quality to support growth and development
  • Prey species of sufficient quantity, quality, and availability to support individual growth, reproduction, and development, as well as overall population growth
  • Passage conditions to allow for migration, resting, and foraging

There was one notable change from the coastal critical habitat NOAA Fisheries originally proposed in November 2019. This was changed to reduce the excluded buffer area around the excluded Quinault Range Site, which is used by the Navy for various training and testing activities in support of military readiness. The final designation also includes a biological explanation of how human-induced noise impacts the conservation value of the designated critical habitat for endangered Southern Resident killer whales.
