Strongest marine heat wave in 40 years off Canada’s East Coast

A severe marine heat wave was recorded off Canada’s East Coast this summer, according to data compiled by Fisheries and Oceans climate scientist Peter Galbraith. The event, lasting from the last three weeks of July to the first week of August, saw a weeklong temperature spike off Newfoundland averaging 6.7 °C (12.1 °F) above normal.

Data confirms robust weakening of the Gulf Stream

A recently published study in the journal Geophysical Research Letters has revealed that the Gulf Stream transport of water through the Florida Straits has weakened by approximately 4% over the past 40 years. Researchers state with 99% certainty that this is more than what would be expected from random variations, marking the first definitive evidence of significant change in the current.

Florida Current at its weakest in the past 110 years

New research by the Woods Hole Oceanographic Institution (WHOI) found that a key component of the Gulf Stream– a warm Atlantic ocean current stretching to the tip of Florida– has steadily slowed and is now weaker than at any other point in the past 110 years. The…

NOAA forecasts larger than average ‘dead ‘zone’ for Gulf of Mexico

The hypoxic area or "dead zone"– an area of reduced oxygen level which kills marine life– in the Gulf of Mexico is forecast to be approximately 10 800 square km (6 700 square miles) larger than the long-term average of about 8 700 square km (5 400 square…
