The renowned "Geophysical Research Letters" journal has unveiled astounding research findings about the Atlantic Ocean. In its equatorial region, there lies a substantial water body, distinct from its surroundings, signifying that the Atlantic Equatorial Waters truly exist. This discovery might compel us to reframe a large part of our comprehension of Planet Earth.

Researchers from the Shirshov Institute of Oceanology have presented compelling evidence, indicating our prevailing understanding of the Atlantic Ocean might be flawed. The massive water body in its equatorial belt, sought after for years, does indeed exist.

Exceptional water masses surround the Equator

For about eight decades, scientists have been aware of the vast water bodies in the equatorial belt that differ significantly from their adjacent water bodies. These masses resemble distinct sea basins within the oceanic realm. They are identifiable by their unique temperature, salinity, chemical composition, and replenishment sources.

Though this phenomenon might appear as an anomaly, it is primarily caused by oceanic currents. The obstacle is that these currents exhibit similar behaviors in the oceanic belt worldwide. However, these distinct equatorial water masses are only detected in the Pacific and the Indian Oceans, while their existence was questionable in the Atlantic.

"It seems astonishing that the equivalent water mass found in the Pacific and Indian Oceans is absent in the Atlantic Ocean. Even though equatorial circulation and mixing in all three oceans share common features, such as bottom current and equatorial waves," - per "Geophysical Research Letters".

Spurred by this background, scientists decided to hunt for the Atlantic Equatorial Waters, employing sensors from the Argo program.

The existence of the Atlantic equatorial waters is confirmed

This is an investigative project undertaken by the University of California, focusing on the global monitoring of oceanic waters. The project utilizes a fleet of automated buoys that are suspended on the ocean surface and measure temperature and salinity worldwide as they float, sink, and drift.

By crunching the data gathered for the Atlantic region, oceanographers established that the Atlantic Equatorial Waters indeed exist. Their stretch lies between Brazil and the African coast of the Gulf of Guinea. This region is where the waters of the southern Atlantic mingle with the northern region of the ocean basin's waters.

Relevance of discovering the Atlantic equatorial waters

The discovery of the Atlantic Equatorial Waters has triggered quite a sensation. This revelation overthrows our understanding of the vast ocean, querying several assumptions in climatology, meteorology, and even marine biology.

Nonetheless, the study's authors underline that their findings should, for now, be perceived as a hypothesis. The pieces of evidence leading to the pinpointing of the Atlantic Equatorial Waters are mainly temperature and salinity.

Though these are critical parameters, The Atlantic waters call for more thorough examination. Further scrutiny of the equator's region of this ocean is required.
