Which of the following is a safety measure in scientific diving?

Using surface markers to indicate diver location is a critical safety measure in scientific diving. These markers serve as visual indicators, allowing boat operators, surface support teams, and other divers to easily track and identify the location of divers submerged underwater. This practice enhances safety by reducing the risk of accidents or entanglement, ensuring that divers can be monitored and assisted if needed.

Maintaining visibility of divers promotes communication and coordination during dives, which is especially important in scientific diving where tasks are often conducted in various underwater environments. Surface markers can also be vital in emergencies, helping to quickly locate divers who may need assistance or when retrieval is required. Overall, the use of surface markers is an essential practice that contributes significantly to the safety of divers while conducting scientific research underwater.
