(ENSO) and Its Impact on Whales:
A Journey Across the Oceans
The world’s oceans are vast, mysterious, and filled with intriguing natural phenomena that profoundly impact marine life, including the magnificent whales that draw nature enthusiasts to Puerto Vallarta for the unforgettable experience of whale watching. One of the most significant phenomena affecting the oceans is the El Niño/Southern Oscillation (ENSO), a complex and periodic climatic event that has a profound impact on marine ecosystems and whale migration.
What is ENSO?
El Niño/Southern Oscillation
ENSO is a complex climatic phenomenon characterized by abnormal warming of sea surface temperatures in the central and eastern equatorial Pacific Ocean. This phenomenon is closely related to changes in atmospheric patterns and affects climatic systems worldwide.

Impact on Oceans and Whales
1. Shifts in Migration Routes: During El Niño events, oceanic conditions undergo drastic changes, affecting the migratory routes of whales. Some species, such as humpback whales, may alter their usual paths in search of warmer waters or to find food that has shifted due to variations in ocean currents.
2. Decreased Food Availability: ENSO can lead to reduced availability of food for whales as it affects biological productivity in the oceans. Whales, relying on certain fish species and krill, are impacted when these organisms decrease due to changes in temperatures and ocean currents.
3. Impact on Reproduction: Whales, relying on optimal conditions for reproduction, may face challenges during El Niño events. Warmer waters can affect reproduction and the care of calves, which can have long-term impacts on whale populations.

Ongoing Study and Conservation Efforts
Understanding how ENSO affects whale migrations and behavior is crucial for the conservation of these incredible marine creatures. Scientific research and careful observation are essential for developing effective conservation and management strategies.
