A Compact, Low-Power In-Situ Flow Analyzer for Marine Applications
A New Tool for In-Situ Analysis is Implemented On an Automated Buoy in the Mediterranean Sea
Continuous monitoring of highly dynamic systems like coastal waters requires frequent sampling in a precise place in order to catch short-term events that might have a strong impact on the ecosystem, such as exceptional phytoplankton blooms or changes caused by storms. The lack of monitoring systems that provide continuous observations of the marine environment, especially concerning chemical species like nutrients in the coastal areas and shelf seas of Europe, is a serious hindrance.
Oceanographers require instruments for m-situ dissolved nutrient analyses. In-situ measurement techniques have many advantages, including avoiding the need to ship storage bottles to land-based laboratories, reducing the risk of sample contamination and allowing for high-frequency measurements. Furthermore, additional and collateral sampling can be performed when special phenomena are identified.
