Surface Piercing Profiler

« Back to Glossary Index

A Surface Piercing Profiler is a type of profiler that is tethered to a mooring-mounted winch at a fixed depth in the water column. As the winch pays out cable, the surface piercing profiler rises through the water column until the profiler pierces the sea surface. Instruments are affixed to the surface piercing profiler, allowing for the measurement of ocean processes at the thin surface layer.
