Alaskan Murre Population Decimated by Marine Heatwave

A marine heatwave in the North Pacific Ocean from late 2014 to 2016 killed approximately 4 million common murres in Alaska, representing half the Alaskan population and the largest single-species die-off in modern history, due to reduced food supply and slow reproductive rates.

How did the decline in Pacific cod contribute to the mass mortality event among common murres?

The die-off highlights the impact of rising ocean temperatures on marine ecosystems. The heatwave's intensity and duration, coupled with the collapse of the Pacific cod population, led to unsustainable mortality rates for common murres. Long-term monitoring data revealed a 52-78% population decrease across 13 colonies, with no recovery observed by 2022.

Alaskan Marine Heatwave Causes Largest Recorded Single-Species Die-off

A marine heatwave in the Gulf of Alaska from 2014-2016 killed approximately 4 million common murres, marking the largest recorded die-off of a single species and highlighting the severe impact of warming ocean temperatures on marine ecosystems.

How did the decline in Pacific cod contribute to the murre die-off, and what broader implications does this have for marine food webs?

The die-off, linked to a decline in the murres' primary food source (Pacific cod), demonstrates how climate change disrupts marine food webs. The lack of recovery even after the heatwave suggests deeper, potentially irreversible ecosystem shifts. This event underscores the urgent need for long-term monitoring of marine populations.

Marine Heat Wave Kills Half of Alaska's Common Murre Population

A 2014-2016 marine heat wave in the North Pacific Ocean, known as 'the blob', killed approximately 4 million common murres in Alaska—half of the population—due to food scarcity caused by the disrupted marine ecosystem. The event severely impacted Alaskan Native communities reliant on the species and...

What was the immediate impact of the 'blob' marine heat wave on Alaska's common murre population, and what caused this impact?

The 2014-2016 marine heat wave, nicknamed 'the blob', caused the largest single-species die-off in modern history, killing approximately 4 million common murres in Alaska—half the population. This resulted from food scarcity due to ecosystem disruption, not direct heat stress.
