Where is buoy 42003

An effort was undertaken to test five buoys after their deployment life to determine the stability of their heading accuracy.

These post-deployment tests showed maximum heading errors ranging from 6 to 8 degrees, which is within NDBC's published overall accuracy of 10 degrees. This capability eliminated the cost of a second buoy and the spatial variability inherent in using two separate buoys for such evaluations.

This comparison will help gauge potential differences in wave height observations from the newer and older systems, with the results, as anticipated by the CHL, used to improve wave models, which draw on NDBC's plus years of wave height observations.

This device contains a nine-axis motion sensor and processor, of which, both are commercially available, but nearing the end of their production life with newer, more power efficient and capable devices available. Thus, newer generation, motion sensors, as well as the possibility of moving the data processing to a modern, Linux-based, embedded platform, are under NDBC evaluation for their possibility of lowering both power demand and cost while maintaining compatibility with NDBC current, wave processing systems and quality standards.
