Abstract

On 10/11/2025 two Karst Underwater Research divers gathered data from the Milk Tunnel in the cave system of Manatee Springs State Park, Levy County, Florida, USA. KUR divers Ken Sallot and Josh Lange ran the YSI EXO3 datasonde into the Milk Tunnel approximately 1400 feet from the main conduit.The datasonde measured water temperature, pH, specific conductivity and dissolved oxygen throughout the dive. A marker (REM) was left at the location that the team turned to return to the main tunnel. After exiting the milk tunnel the dive team continued upstream to the fracture (fissure) a karst feature approx. 4500 ft penetration upstream from Friedmans Sink then returned to exit at Catfish Hotel Sink..Total dive runtime was 190 minutes, a dive computer download along with timestamp information to help synchronize the datasonde data with various parts of the cave are included.

manatee_run04_10-11-25_narrative.txt is the dive teams description of the dive.

Manatee_run04_wetnote.png is a photo or screenshot of the divers underwater notebook detailing the timing of when certain karst features or directional decisions were made. This is to assist in the interpretation of real-time data from the YSI EXO3 datasonde carried by the dive time. 

manatee_run04_10-11-25_rawdata.xlsx is the dataset as downloaded from the YSI EXO3 datasonde. This contains real-time temperature, pH, specific conductivity, and dissolved oxygen readings.

manatee_run04_10-11-25.xlsx contains processed and graphed data from the associated raw data file.

manatee_run04_10-11-25_divelog.csv contained data downloaded from the diver's Shearwater dive computer containing dive depth profile information.
