10 Major Gulfs In North America

North America is a continent of myriad landscapes and geographical features. It is also home to several gulfs that have shaped its history, culture and economy. The expansive water bodies surrounding the continent’s coastlines offer much more than natural beauty.

They are bearers of essential maritime routes, ecosystems and hubs of famous recreational activities. In this article, we will uncover the unique characteristics and importance of the major North American Gulfs.

Right from the icy waters of the Alaska Gulf to the tropical feel of the Gulf of Mexico, each gulf has a unique history of evolution and human interaction. The Gulfs in North America harbour diverse marine life and have facilitated trade between nations for hundreds of years.

These major gulfs also provide deep insights into the connections and linkages between North America’s aquatic ecosystems and communities residing near them, depending on their precious resources for livelihood.

By comprehending the role played by these gulfs, we can truly appreciate North America’s relations with the surrounding water bodies and its global impact on different sectors.

Read along as we dive into the major North American Gulfs, highlighting their features and significance in the present world.

1. Gulf of Mexico

The Gulf of Mexico lies on the southeastern coast of North America and is connected to the Atlantic Ocean via the Florida Straits. It is linked to the Carribean Sea through the Yucatan Channel.

The Gulf of Mexico was formed around 300 million years ago due to plate tectonics. Covering around 600,000 square miles, its basin is oval in shape, having a width of 810 nautical miles. Its floor is lined with sedimentary rocks and sediments.

Principal ports on the Gulf are Veracruz in Mexico and New Orleans, Galveston, Tampa and Pensacola in the U.S.

The Gulf faces many environmental threats, including agricultural runoff and oil drilling. Red tide or algae blooms that kill marine life and lead to respiratory issues in humans, and animals are frequent near the gulf’s shores, especially along the Florida coast.

It has been reported to have high concentrations of microplastic. There are 27,000 abandoned oil and gas wells beneath the gulf.

2. Gulf of Alaska

An arm of the Pacific Ocean, the Gulf of Alaska covers 1,533,000 km2, spanning from Kodiak Island and the Alaska Peninsula to the Alexander Archipelago situated at Glacier Bay.

Its highly productive ecosystem contains many deep-water corals, leading to the categorisation of the gulf as a Habitat Area of Particular Concern.

The Gulf of Alaska is also famous since the two oceans meet but never mix here. It has two kinds of water, natural bluewater and heavy sediment water.

3. Gulf of California

The Gulf of California, a marginal water body of the Pacific Ocean, is also called the Sea of Cortes or the Vermilion Sea.

It separates the Baja California Peninsula from mainland Mexico. It has a long coastline stretching to approximately 4000 kilometres.

Gulf of California

Several rivers flow into the Gulf of California, including the Fuerte, Sinaloa, Mayo, Sonora etc.

The gulf’s surface spans 160,000 square kilometres while its maximum depths are over 3000 m due to its complicated geology, a consequence of plate tectonic movements.

It is known to be a diverse and productive sea harbouring over 5000 micro-invertebrate species, making it a UNESCO World Heritage Site.

The gulf is a rich source of fisheries and is also home to 37 islands, the two biggest being Isla Ángel de la Guarda and Isla Tiburón.

4. Gulf of Honduras

An inlet of the Caribbean Sea, the Gulf or the Bay of Honduras indents the shores of Guatemala, Belize and Honduras. It spans 200 km from Dangriga to La Ceiba and receives 300,000 gallons of water per second from 12 major rivers.
