Turbidity currents are underwater sediment flows that move across the seafloor, similar to avalanches. These flows can be fast but short-lived or slower and longer-lasting. To understand their behavior, we analyzed data from underwater canyons, deltas, and experiments, examining how flow velocities evolve over time and how temporal patterns are influenced by triggers, slope, sediment size, and distance from the source. While trends emerge-short-lived flows in sandy near-shore systems and sustained flows offshore in fine-grained systems-no single factor fully explains the observed variability. This study underscores the need for better data on sediment sizes within systems to improve understanding of these complex flows.
