Instrument: Roller Tank

Instrument Short Name: Roller Tank
Instrument Description:

Rolling tanks, which keep particles in suspension, thus simulating aggregate formation in situ.

Marine snow experiments are conducted in roller tanks, which turn continuously, keeping marine snow in suspension. It is important for marine snow not to touch surfaces. The rolling tanks, which keep particles in suspension, thus simulate aggregate formation in situ. Marine snow formation due to different types of oil was tested. Some treatments are easily identifiable as containing oil by their color (middle). UCSB, CA 2012.

Dataset-specific description

Roller tanks experiments: 14 cylindrical five-liter roller tanks/ treatments rotating at 1 rpm encompassing three acidification scenarios and 5 concentrations of the clay illite incubated at 14oC in continuous darkness for 44 to 48 hours. Solid body rotation was established within three hours.
