Gulf of Maine Warming Updates
Tracking temperatures in the Gulf of Maine.
Over the past decade, scientists at the Gulf of Maine Research Institute have led a body of research that highlights the rapid pace of warming in the Gulf of Maine. To keep you informed, we share seasonal and annual updates about conditions in the Gulf of Maine.
The Gulf of Maine is warming faster than almost any other ocean surface on the planet.
- This is important because the rate of change can have profound consequences for the biology of individual species and for entire food webs.
- Better understanding the warming rate can help us work with coastal communities to ensure that the rate of warming doesn't outpace adaptation and resilience strategies.
- Because the Gulf of Maine is warming faster than almost any other ocean surface on the planet, what we learn here is instructive elsewhere.

Annual Warming Updates

Seasonal Warming Updates
In addition to annual warming updates, we also take time to break down warming in the Gulf of Maine by season. This helps us identify specific trends, including that the fall and winter seasons seem to be warming at a faster rate that spring and summer seasons.
