October 24, 2023 — The endangered North Atlantic right whale population may have grown slightly with new calves born in 2021-2023. But human activities in the ocean could still be killing as many whales as are born, scientists say in their latest assessment.
In a report released for its annual meeting this week, the North Atlantic Right Whale Consortium updated its estimate for the 2022 whale population at 356 animals, based on 18 calves born in 2021, according to a summary from the New England Aquarium.
“While certainly more encouraging than a continued decline, the ‘flattening’ of the population estimate indicates that human activities are killing as many whales as are being born into the population, creating an untenable burden on the species,” said Heather Pettis, a research scientist in the Anderson Cabot Center for Ocean Life at the New England Aquarium and executive administrator of the North Atlantic Right Whale Consortium.
The aquarium and science partners at the National Oceanic and Atmospheric Administration work together on coordinating surveys of the right whale population – one of the most endangered species on Earth – and NOAA published a detailed technical memo on the latest assessment Oct. 23.
