ARTICLE EVALUATION
Content.

The article provides relative information on the topic, however, the information is insufficient. It misses a lot of detail, or images that would help the reader form a complete picture of the "Aquatic sill", its formation and its effects on the surrounding environment. It includes examples of locations and few links to related topics, however, some of the facts provided are left unexplained. Overall, more scientific information could be added to help clarify the topic at hand.

Tone.

The tone of the article is neutral and there aren't any claims that appear to be biased. No viewpoints displayed.

Sources.

The article includes two sources and they are both active and neutral. The first source is from a website maintained by GRID-Arendal and provides reliable information that supports the article. The second source links to a page that seems outdated and unreliable. The article is classified as a stub and needs further coverage and verification from sources.

Talk Page.

The article is currently the subject of a Wiki Education Foundation-supported course assignment and it is within the scope of Wiki Project Oceans. It has been rated as Start-Class on the project's quality scale and Low-importance on its importance scale.

ASSIGNMENT 3: DRAFT YOUR CONTIRBUTIONS
An aquatic sill (or an oceanic sill) is a sea floor barrier of relatively shallow depth restricting water movement between oceanic basins. A similar barrier can also exist on a lake floor.

The Straight of Gibraltar Gateway
The sill of the Straight of Gibraltar, also known at the Straight of Gibraltar Gateway, is a type example of a sill. It connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa. The morphological and oceanographic gateway is a result of the Messinian Crisis, the Zanclean Flood, and the late Miocene tectonic movements.

During the Messinian Crisis, around 5.96-5.33 million years ago, the Mediterranean Sea experienced a near complete drought, which in combination with the post Messinian flooding (Zanclean Flood) that followed, resulted in the scouring of two deep channels (Canal Norte and Sur). At the end of the Messinian (Late Miocene) and during the Early Pliocene period, a North-South dominated tectonic stress field created pull-apart basins under a transtentional regime, creating the Atlantic-Mediterranean gateway.

The sill, with elevated seabed topography, is characterized by two "mounts" (Monte Seco and Monte Tartesos), separated by East-West oriented depressions and North-South elevated morphological structures. It is characterized by rocky seabed, low, muddy sedimentation, and cold water coral accumulations.
