AI-Enabled Study Reveals Alarming Decline in North Pacific Humpback Whale Population


  • AI study shows a 20% drop in humpback whales from 2012-2021 due to heatwave.
  • AI identifies 30,000 whales, revealing climate change’s impact on oceans.
  • Collaboration is needed for conservation as humpback populations decline.

A recent study published in Royal Society Open Science has shed light on a concerning trend in the humpback whale population of the North Pacific Ocean. Utilizing a groundbreaking combination of marine biology and artificial intelligence (AI) technology, researchers have uncovered a significant decline in humpback whale numbers attributed to the devastating effects of a marine heatwave.

Between 2012 and 2021, approximately 7,000 humpback whales perished due to the prolonged marine heatwave, marking a staggering 20% decrease in the population during this period. This heatwave, which began in 2013 and persisted until 2021, significantly elevated water temperatures and disrupted oceanic productivity globally.

AI-powered insights

The study, spearheaded by Dr. Ted Cheeseman and a team of researchers, harnessed AI technology to analyze data and images sourced from 46 organizations and over 4,000 community science contributors. Through AI-powered automated image recognition, the researchers efficiently matched and identified individual humpback whales, enabling the compilation of data for over 30,000 whales across the globe.

The marine heatwave, commonly called “the blob,” profoundly influenced the ecosystem, leading to depleted nutrient levels in phytoplankton and cascading effects up the food chain. Consequently, humpback whales, alongside other marine species such as sea lions and sea birds, faced significant food shortages, contributing to the observed population decline.

Collaborative efforts and citizen science

Integrating AI technology facilitated more comprehensive data collection and fostered collaboration among researchers and citizen scientists. Platforms like Happywhale served as invaluable repositories for whale images and data, with nearly 800,000 photos submitted to date, leading to the identification of over 100,000 individual whales. This crowdsourcing approach has democratized scientific research and amplified public engagement in marine conservation efforts.

Despite the remarkable recovery of humpback whale populations following the cessation of commercial whaling in 1986, the study underscores the sobering reality of climate change’s impact on marine ecosystems. Dr. John Calambokidis emphasized the imperative of conservation efforts in light of these findings, highlighting the critical role of public awareness and policy interventions in safeguarding vulnerable species.

While the study serves as a wake-up call to the ecological consequences of climate-driven phenomena, it also raises pertinent questions about the resilience of marine ecosystems in the face of escalating environmental challenges. Dr. Ari Friedlaender emphasized the need for proactive conservation strategies to mitigate the impact of marine heatwaves and safeguard marine biodiversity for future generations.

The intersection of marine biology and AI technology has enabled researchers to uncover a troubling decline in humpback whale populations, underscoring the urgency of concerted conservation efforts. By harnessing the power of AI and fostering collaborative partnerships, scientists aim to deepen our understanding of marine ecosystems and implement effective measures to mitigate the threats posed by climate change.
