Earth Sciences Does this underwater formation have a name?

It looks so interesting and I have no idea how to find information about it. I'm so curious as to what it could look like down there as well as what kind of sea creatures live there and so much more

Enjoy the GEBCO Gazetteer. The specific feature you marked is one of the three features named the "Acapulco Seamounts". The one you've marked is more generally something we call a guyot, which makes me wonder if the other feature that shows in that area (the Dowd guyot) in the gazetteer is supposed be centered on the same feature you marked and there's just a bit of a location error (cause the thing that is marked as the Dowd guyot looks nothing like a guyot).

Guyots were first recognized in 1945 by Harry Hammond Hess, who collected data using echo-sounding equipment on a ship he commanded during World War II.[4] His data showed that some undersea mountains had flat tops. Hess called these undersea mountains "guyots", after the Department of Geosciences building at Princeton

Which was itself named in honour of this guy.

Looks like they’re having some faculty restructuring, with geosciences being housed elsewhere and comp sci moving in to that building. Also looks like they’ve taken the opportunity to rename it, probably because of this (from the wiki article):

Guyot's ‘Earth and Man’ lecture series describes how geography — particularly the distribution of continents, topography, and climate regions — determines the superiority or inferiority of human races in terms of beauty, physical ability, intelligence, and morality. Through these lectures, Guyot promulgated theories of scientific racism to a wide audience in New England, including the general public and teachers who were eager to incorporate this material into their classes.

And then served as a possible inspiration for the name of this guy!

underwater volcanic mountain (seamount) with a flat top more than 200 m (660 ft) below the surface of the sea

the first two features i get, but what is the significance that it has to be below 200m? the wiki article doesn't mention it again, except for one line that maybe has to do with it?

In addition, the erosive effects of waves and currents are found mostly near the surface: the tops of guyots generally lie below this higher-erosion zone.

is the 200m the zone of higher erosion?
