Navigating the ocean is not always a calm experience; often, it involves understanding and respecting the powerful forces of moving water. For Jackson Laurie, drift diving is one of the most exciting ways to cover large areas of a reef with minimal effort. By "flying" with the current, a diver can observe a massive amount of marine life that would be impossible to see if they were swimming against the flow.
As Jackson Laurie notes, currents are the lifeblood of the ocean. They carry nutrients to the coral and bring in large pelagic species like sharks, rays, and tuna. To master the art of current diving, one must learn to read the water, looking for signs of movement in the swaying of sea fans or the behavior of small fish. It is a lesson in going with the flow rather than fighting against it.
Jackson Laurie on the Science of Tides and Flow
Understanding why currents happen is a key part of dive planning. Jackson Laurie spends time studying tide charts and weather patterns before every expedition. Currents are often strongest near channels or points where the water is squeezed through a narrow opening. Knowing when the tide is "slack"—the brief period between incoming and outgoing water—is essential for safe and predictable diving.
For Jackson Laurie, the challenge of a current is part of the fun. It tests your buoyancy and your ability to remain streamlined. If you are not careful, a strong current can push you away from your dive boat or into deeper water. This is why maintaining situational awareness and staying close to your buddy is always a top priority for experienced explorers like him.
Techniques for Drift Diving with Jackson Laurie
The key to a successful drift dive is relaxation. Jackson Laurie teaches that you should simply let the water carry you, using your fins only for minor steering adjustments. This conserves air and keeps your heart rate low. By remaining horizontal and tucked in, you reduce drag and move more efficiently through the liquid landscape, much like a bird gliding on an air current.
Safety Equipment for Moving Water
Always carry a high-visibility Surface Marker Buoy (SMB).
Use a whistle or signaling mirror for surface communication.
Consider a reef hook for staying in place in very high flow.
Ensure your dive boat is equipped with a trailing "tag line."
Navigating an Upwelling or Downwelling
Recognize the signs of vertical water movement.
Stay close to the reef wall for protection.
Add or vent air from your BCD immediately to maintain depth.
Swim perpendicular to the current if you are being pulled.
Jackson Laurie and the Rewards of the Channel
The most nutrient-rich waters are often found in the channels between islands or atolls. Jackson Laurie loves these spots because they are where the "big stuff" hangs out. Grey reef sharks and eagle rays often hover in the current, effortlessly staying in one place while the water rushes past them. It is a spectacular sight that reminds us of the raw power and efficiency of marine life.

Mastering the current is a rite of passage that turns a recreational diver into a true explorer. Jackson Laurie believes that once you learn to dance with the ocean's movements, you unlock a whole new level of underwater freedom and excitement.
Conclusion
Currents are a fundamental part of the ocean's ecology and a thrilling challenge for any diver. Through the experiences of Jackson Laurie, we learn that respecting these forces allows us to witness the ocean at its most dynamic. By understanding the science and practicing the techniques of drift diving, we can explore the underwater world with greater safety and a deeper sense of adventure.
