A simple multilevel sampler for synchronous collection of stratified waters

Stratified water collection plays a crucial role in water quality monitoring, as most water bodies are not perfectly mixed systems. In order to precisely collect stratified waters, we developed an inexpensive, simple, and high-resolution sampler to simultaneously collect and measure physical and che...

Description
Summary:Stratified water collection plays a crucial role in water quality monitoring, as most water bodies are not perfectly mixed systems. In order to precisely collect stratified waters, we developed an inexpensive, simple, and high-resolution sampler to simultaneously collect and measure physical and chemical parameters along vertical water profiles. The water sampler predominantly consists of two parts: (1) an apparatus for measuring sampling depth below the water and (2) water sampling units secured below the water. Proof of concept water sampling was performed in Caohai wetland (Southwest China) at 40 cm intervals, as sampling depth and interval are adjustable. Stratified waters in four sampling sites were characterized by markedly different levels of major and trace elements as well as physicochemical parameters. Results indicate this simple multilevel sampler to be a cheap, precise, and portable option for simultaneously collecting water samples at different depths in a wide array of water body types.
