LVF Liquid volume fraction is the ratio of the liquid volumetric flow rate to the total volumetric flow rate.

Ocean currents are measured in sverdrup (sv), where 1 sv is equivalent to a volume flow rate of per second.

Various international organizations, including the Council of Europe, OECD and the United Nations have invited all countries to take steps to increase the current efforts and to lower the size limit of this search to objects in the 200 300 m diameter range.
