The mosaic features ten maidens who have been anachronistically dubbed the "Bikini Girls". Other Roman archaeological finds depict the goddess Venus in a similar garment. In Pompeii, depictions of Venus wearing a bikini were discovered in the Casa della Venere, in the "tablinum" of the House of Julia Felix, and in an atrium garden of Via Dell'Abbondanza. In the 1920s the term was applied to a simply shaped brassiere, usually of a
Ice shelf most of the continent's ice shelf mass loss. Typically, a shelf front will extend forward for years or decades between major calving events. Snow accumulation on the upper surface and melting from the lower surface are also important to the "mass balance" of an ice shelf. Ice may also accrete onto the underside of the shelf. The density contrast between glacial ice and liquid water means that at least 1/9 of the floating ice is above the ocean surface, depending on how much pressurized air is contained in the bubbles within the glacial ice, stemming from compressed snow. The formula
