MARITIME – DIVE & UNDERWATER OPERATION CALCULATOR
Dive Decompression Stop
A precise tool.
What is the Dive Decompression Stop & How does it work?
Decompression stops are required to allow inert gases absorbed under pressure to be released safely during ascent, preventing the formation of bubbles that can cause decompression sickness.
The required stop duration depends primarily on the maximum depth reached and the total bottom time spent at that depth. Greater depth and longer exposure increase nitrogen loading, thus lengthening the necessary stop.
Using this simplified linear model, divers can estimate a safe stop time, but for operational planning always refer to validated dive tables or computer algorithms.
\\text{Stop}=\\frac{\\text{Depth}-20}{10}\\times\\frac{\\text{BottomTime}}{20}
Stop = decompression stop time (minutes)

Frequently Asked Questions
What is a decompression stop in scuba diving?
A decompression stop is a pause during ascent to allow inert gases absorbed under pressure to safely release, preventing decompression sickness.
How does depth affect decompression stops?
Greater depth increases nitrogen loading, requiring longer decompression stops to prevent the formation of bubbles that can cause decompression sickness.
What is the purpose of a decompression calculator?
A decompression calculator helps divers estimate safe stop times based on their dive profile to avoid decompression sickness.
How does bottom time influence decompression stops?
Longer exposure at depth increases nitrogen absorption, thus necessitating longer decompression stops to safely off-gas inert gases.
Can I use this calculator for any type of diving?
This simplified model is suitable for recreational scuba diving. For technical or deep diving, consult a professional dive planner.
What should I do if I miss a decompression stop?
If you miss a decompression stop, ascend slowly and consider doing an additional safety stop to reduce the risk of decompression sickness.
Are there any factors that can affect the accuracy of this calculator?
Yes, factors such as water temperature, dive equipment, diver's physical condition, and individual gas consumption rates can affect the accuracy of the calculation.
