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.
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 user who wants to explore Argo data but lacks programming skills might like to download the Argo Global Marine Atlas [14] which is an easy-to-use utility that allows the creation of products based on Argo data such as the salinity section shown above, but also horizontal maps of ocean properties, time series at any location etc. This Atlas ...
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.
Both Physalia and Velella poses "sails", which allow them to travel based on wind direction. [15] These by-the-wind sailors float near the surface of the ocean with their tentacles hanging below in the water. Velella has a raised transparent "sail" on a blue oval disk. Short fringing tentacles hang below from the disc.
The 300-plus-year-old glass onion bottles were discovered from the 1715 Treasure Fleet shipwreck, located off the coast of Florida. ... the ships remained untouched in the Atlantic Ocean. Today ...
If that fails, saving an astronaut floating off into space might require several tethers hooked together, a SAFER, and, to be honest, a lot of luck. RELATED: Here's whats happening in space this year:
Moored FADs occupy a fixed location and attach to the sea bottom using a weight such as a concrete block. A rope made of floating synthetics such as polypropylene attaches to the mooring and in turn attaches to a buoy. The buoy can float at the surface (lasting 3–4 years) or lie subsurface to avoid detection and surface hazards such as ...
