What you'll learn

  • How a Chilean marine engineering firm moved past a decades old, three-times-a-day manual wave reading and scaled real-time monitoring across more than 1,800 kilometers of coast.
  • How Port of Lyttelton, New Zealand rebuilt its offshore wave monitoring at a fraction of its original buoy cost, without losing the data its under-keel clearance system depends on.
  • For each distinct region, what measurements are actually needed in the water to close the monitoring gap and how to plan around your ports needs.
