Sastrugi dunes, and the resulting drifting snow shapes are also popularly referred to as "barchans". Inuit of Canada call them "kalutoqaniq". When winds slacken, the drifted formations consolidate via sublimation and recrystallization. Subsequent winds erode kalutoqaniq into the sculptured forms of sastrugi. Inuit call large sculpturings "kaioqlaq" and small ripples "tumarinyiq". Further erosion may turn "kaioqlaq" back into drifting "kalutoqaniq". An intermediate stage of erosion is "mapsuk", an overhanging shape. On the windward side of a ridge, the base erodes faster than the top, producing a shape like an anvil tip pointing upwind. Sastrugi are more likely to form on first-year
Surface wave detection by animals level for surface wave-detecting neuromasts has been minimally investigated. In this regard what research has been done shows considerable variation between species; in A lineatus, these neuromasts are considered the supraorbital line, and are innervated by ramus opthalmicus superficialis. This tract results in collateral fibers that innervate the rostral boundary of the medial octavolateralis nucleus, the area in all teleosts where lateral line organs innervate. These afferents also go to the valvula cerebelli. In one of the few electrophysiology studies performed on "A lineatus", it was found that of all the primary afferents from neuromasts that they recorded, half phase-locked
