What type of gases might be present in dry chambers of flooded caves?

In dry chambers of flooded caves, the presence of toxic gases is a significant concern. These gases can accumulate due to organic material decomposition, the activity of microorganisms, or geological processes occurring in the confined environment of the cave. Common toxic gases that might be found include hydrogen sulfide, carbon dioxide, and methane.

Understanding the environmental conditions in flooded caves is crucial for divers, as the buildup of these gases can create hazardous situations, potentially leading to incapacitation or loss of consciousness if inhaled in high concentrations. Therefore, awareness of toxic gases is essential for divers operating in such environments, making it a critical part of cavern diving safety protocols and training.
