Where the dive site and underwater topography permit, divers often prefer to descend initially to maximum depth and slowly ascend throughout the dive. A slow ascent, and therefore slow pressure reduction, is a good decompression practice.
In environments where it's safe to do so, divers often start by reaching the greatest depth and then ascend at a relaxed pace throughout the dive. This slow ascent, which also results in a slower decrease in pressure, helps ensure a safe decompression process.
