More than 100 Dolphins Found Dead in Brazilian Amazon as Water Temperatures Soar

More than 100 dolphins have died in the Brazilian Amazon rainforest in the past week as the region grapples with a severe drought, and many more could die soon if water temperatures remain high, experts say.

The Mamiraua Institute, a research group of Brazil’s Ministry of Science, Technology and Innovation, said two more dead dolphins were found Monday in the region around Tefe Lake, which is key for mammals and fish in the area. Video provided by the institute showed vultures picking at the dolphin carcasses beached on the lakeside. Thousands of fish have also died, local media reported.

Experts believe high water temperatures are the most likely cause of the deaths in the lakes in the region. Temperatures since last week have exceeded 39 degrees Celsius (102 degrees Fahrenheit) in the Tefe Lake region.

The Brazilian government’s Chico Mendes Institute for Biodiversity Conservation, which manages conservation areas, said last week it had sent teams of veterinarians and aquatic mammal experts to investigate the deaths.

There had been some 1,400 river dolphins in Tefe Lake, said Miriam Marmontel, a researcher from the Mamiraua Institute.

“In one week we have already lost around 120 animals between the two of them, which could represent 5% to 10% of the population,” said Marmontel.

Workers have recovered carcasses of dolphins since last week in a region where dry rivers have impacted impoverished riverside communities and stuck their boats in the sand. Amazonas Gov. Wilson Lima on Friday declared a state of emergency due to the drought.

Nicson Marreira, mayor of Tefe, a city of 60,000 residents. said his government was unable to deliver food directly to some isolated communities because the rivers are dry.

Ayan Fleischmann, the Geospatial coordinator at the Mamirauá Institute, said the drought has had a major impact on the riverside communities in the Amazon region.

“Many communities are becoming isolated, without access to good quality water, without access to the river, which is their main means of transportation,” he said.

Fleischmann said water temperatures rose from 32 C (89 F) on Friday to almost 38 C (100 F) on Sunday.

He said they are still determining the cause of the dolphin deaths but that the high temperature remains the main candidate.

OceanGate co-founder Stockton Rush said the carbon fiber hull used in an experimental submersible that imploded en route to the wreckage of the Titanic was developed with help of NASA and aerospace manufacturers, but a NASA official testified Thursday that the space agency actually had little involvement at all.
OceanGate and NASA partnered in 2020 with NASA planning to play a role in building and testing the carbon fiber hull. But the COVID-19 pandemic prevented NASA from fulfilling its role, other than providing some consulting on an early mockup, not the ultimate carbon fiber hull that was used for people, said Justin Jackson, a materials engineer for NASA.
“We provided remote consultations throughout the build of their one third scale article, but we did not do any manufacturing or testing of their cylinders,” The Associated Press quoted Jackson as saying.
At one point, Jackson said NASA declined to allow its name to be invoked in a news release by OceanGate. “The language they were using was getting too close to us endorsing, so our folks had some heartburn with the endorsement level of it,” he told a Coast Guard panel that’s investigating the tragedy.
Rush was among the five people who died when the submersible imploded in June 2023. The design of the company's Titan submersible has been the source of scrutiny since the disaster.
The Coast Guard opened a public hearing earlier this month that is part of a high level investigation into the cause of the implosion. Some of the testimony has focused on the troubled nature of the company.
In addition to Jackson, Thursday's testimony was to include Mark Negley of Boeing Co.; John Winters of Coast Guard Sector Puget Sound; and Lt. Cmdr. Jonathan Duffett of the Coast Guard Office of Commercial Vessel Compliance.
Earlier in the hearing, former OceanGate operations director David Lochridge said he frequently clashed with Rush and felt the company was committed only to making money. “The whole idea behind the company was to make money,” Lochridge testified. “There was very little in the way of science.”
Lochridge and other previous witnesses painted a picture of a company that was impatient to get its unconventionally designed craft into the water. The accident set off a worldwide debate about the future of private undersea exploration.
The hearing is expected to run through Friday and include more witnesses.
The co-founder of the company told the Coast Guard panel Monday that he hoped a silver lining of the disaster is that it will inspire a renewed interest in exploration, including the deepest waters of the world’s oceans. Businessman Guillermo Sohnlein, who helped found OceanGate with Rush, ultimately left the company before the Titan disaster.
“This can’t be the end of deep ocean exploration. This can’t be the end of deep-diving submersibles and I don’t believe that it will be,” Sohnlein said.
Coast Guard officials noted at the start of the hearing that the submersible had not been independently reviewed, as is standard practice. That and Titan’s unusual design subjected it to scrutiny in the undersea exploration community.
OceanGate, based in Washington state, suspended its operations after the implosion. The company has no full-time employees currently, but has been represented by an attorney during the hearing.
During the submersible’s final dive on June 18, 2023, the crew lost contact after an exchange of texts about Titan’s depth and weight as it descended. The support ship Polar Prince then sent repeated messages asking if Titan could still see the ship on its onboard display.
One of the last messages from Titan’s crew to Polar Prince before the submersible imploded stated, “all good here,” according to a visual re-creation presented earlier in the hearing.
When the submersible was reported overdue, rescuers rushed ships, planes and other equipment to an area about 435 miles (700 kilometers) south of St. John’s, Newfoundland. Wreckage of the Titan was subsequently found on the ocean floor about 330 yards (300 meters) off the bow of the Titanic, Coast Guard officials said. No one on board survived.
OceanGate said it has been fully cooperating with the Coast Guard and NTSB investigations since they began. Titan had been making voyages to the Titanic wreckage site going back to 2021.
