Parameters: Fluorescent Dye Tracing, Fluorescein

In April-May 2018, a group of glaciologists led by PhD student Katie Miles at Aberystwyth University used four PME Cyclops-7 Loggers in combination with fluorescein-detecting Cyclops-7F Submersible Sensors on Khumbu Glacier, Nepal. Khumbu Glacier, whose ice is sourced in the Western Cwm of Mount Everest, flows down the flanks of the mountain from around 7,000 to 4,900 metres above sea level.

The aim of the project was to determine the subsurface dra...

Parameters: Fluorescein

The Philadelphia Water Department conducted a dye test in the Delaware River between August 5 and August 8, 2014, as part of the validation process for a 3D hydrodynamic model using Environmental Fluid Dynamics Code.  They are updating a flow model that will help them better understand how pollutants are dispersed in the tidal Delaware.  This flow model is one of the scientific tools used in their Green City Clean Waters Plan to better protect and improve the quality of th...
