A rosette sampler is used for collecting water samples in deep water, such as the Great Lakes or oceans, for water quality testing.
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage.[1][2] It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extent of water pollution and condition of drinking water. Water quality has a significant impact on water supply and oftentimes determines supply options.[3]
