CDIP buoy 163 sits at Majuro Atoll, the capital and most populous atoll of the Republic of the Marshall Islands. Majuro is exposed to open Pacific swell from multiple directions and is one of the most climate-vulnerable places on Earth — wave data is critical for both daily ocean activity and long-term climate adaptation work.

Majuro is a low-lying atoll — wave data here is also flood-warning data. King-tide events combined with N swell can overtop the road.
For most CDIP buoys, the use case is surf and fishing. For Majuro, it's also overtopping and erosion monitoring. The Marshall Islands sit just 7 feet above sea level on average. Buoy 163 is part of the data infrastructure communities use to track when the ocean is going to spill over the road.
