Ocean current-following surface drifters
Map showing the paths that ocean current-following surface drifters deployed in coral larval slicks off west Maui traveled in 24 hours following their release during a coral spawning event. Such data suggests that the coral reefs off west-central Maui may provide coral larvae to the reefs off northeastern Lānaʻi.

Spectral Analysis of Surface Waves testing
The preferred method of SASW testing uses a continuous harmonic-wave source produced by a low-frequency computer-controlled electromechanical shaker (device at right) and multi-sensor linear seismometer arrays (2-sensors on the left). This site is 600-PS11, at Trans Alaska Pipeline, Alyeska Pump Station 11, Glennallen, Alaska.
