This is the etymology of apron as given in the Macquarie Dictionary.
[ME napron (napron being later taken as an apron), from OF naperon, diminutive of nape, from L nappa napkin, cloth]
I didn't include it in the article as I'm unsure if to do so would breach copyright. —This comment was unsigned.

According to http://www.geonames.org/export/codes.html An apron is listed in the category U undersea APNU apron a gentle slope, with a generally smooth surface, particularly found around groups of islands and seamounts
According to Wikipedia, it focus on the Clothing defintion, so i believe that Wikipedia should also be corrected Looking at http://en.wikipedia.org/wiki/Apron_(disambiguation) It lists, "Another term for linkspan, and is used as a ramp to connect shoreside facilities with a barge or ferry at a ferry slip."
However, the source of geonames is from the USGS (i believe), and it seems that the term is used to show the underwater linkage for islands. ie. if the tide was low enough, it would be visable and called a "Tombolo" http://www.openstreetmap.org/browse/node/544332865 http://en.wikipedia.org/wiki/Tombolo http://en.wiktionary.org/wiki/tombolo
So this would be an undersea tombolo? ie. fully submerged, and a danger to marine navigation.
