Float glass is a sheet of glass made by floating molten glass on a bed of molten metal of a low melting point, typically tin, [1] although lead was used for the process in the past. [2] This method gives the sheet uniform thickness and a very flat surface. [ 3 ]
A float can collect data while it is neutrally buoyant or moving through the water column. Often, floats are treated as disposable, as the expense of recovering them from remote areas of the ocean is prohibitive; when the batteries fail, a float ceases to function, and drifts at depth until it runs aground or floods and sinks.
A Japanese glass fishing float. Glass floats were used by fishermen in many parts of the world to keep their fishing nets, as well as longlines or droplines, afloat.. Large groups of fishnets strung together, sometimes 50 miles (80 km) long, were set adrift in the ocean and supported near the surface by hollow glass balls or cylinders containing air to give them buoyancy.
About 44 million people live inside the 185km-wide (115 mile) path of totality stretching from Mexico to Canada, with 32 million of them in the US.
The company's headquarters and main factories were located in Toledo, Ohio, with large float glass plants in Rossford, Ohio, Laurinburg, North Carolina, Ottawa, Illinois, Shreveport, Louisiana, and Lathrop, California. The company was formed in 1930 by the merger of Libbey-Owens's sheet-glass operation with the Edward Ford Plate Glass Company ...

Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
