In Greek mythology, Proteus is an early prophetic sea god or god of rivers and oceanic bodies of water, one of several deities whom Homer calls the "Old Man of the Sea". Some who ascribe a specific domain to Proteus call him the god of "elusive sea change", which suggests the changeable nature of the sea or the liquid quality of water. He can foretell the future, but, in a mytheme familiar to several cultures, will change his shape to avoid doing so; he answers only to those who are capable of capturing him. From this feature of Proteus comes the adjective protean, meaning "versatile", "mutable", or "capable of assuming many forms". "Protean" has positive connotations of flexibility, versatility and adaptability.
In Greek mythology, Leucothea, sometimes also called Leucothoe, was one of the aspects under which an ancient sea goddess was recognized, in this case as a transformed nymph.
In marine geology, a guyot, also called a tablemount, is an isolated underwater volcanic mountain (seamount) with a flat top more than 200 m (660 ft) below the surface of the sea. The diameters of these flat summits can exceed 10 km (6 mi). Guyots are most commonly found in the Pacific Ocean, but they have been identified in all the oceans except the Arctic Ocean. They are analogous to tables on land.

Jesus walking on the water, or on the sea, is recorded as one of the miracles of Jesus recounted in the New Testament. There are accounts of this event in three Gospels—Matthew, Mark, and John—but it is not included in the Gospel of Luke. This story, following the miracle of the feeding of the five thousand, tells how Jesus sent the disciples by ship back to the "other side" of the Sea of Galilee while he remained behind, alone, to pray. Night fell and the sea arose as the ship became caught in a wind storm. After rowing against the wind for most of the night, the disciples saw Jesus walking on the water. They were frightened, thinking that they were seeing a spirit, but when Jesus told them not to be afraid, they were reassured. After Jesus entered the ship, the wind ceased, and they arrived at land.
"Riddles Wisely Expounded" is a traditional English song, dating at least to 1450. It is Child Ballad 1 and Roud 161, and exists in several variants. The first known tune was attached to it in 1719.

Sealioning is a type of trolling or harassment that consists of pursuing people with relentless requests for evidence, often tangential or previously addressed, while maintaining a pretense of civility and sincerity, and feigning ignorance of the subject matter. It may take the form of "incessant, bad-faith invitations to engage in debate", and has been likened to a denial-of-service attack targeted at human beings. The term originated with a 2014 strip of the webcomic Wondermark by David Malki, which The Independent called "the most apt description of Twitter you'll ever see".

Height above mean sea level is a measure of a location's vertical distance in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods. Climate change and other forces can cause sea levels and elevations to vary over time.
