Disparate Data for Marine Life
Remote sensing data helps to inform ocean planning for energy development around the main Hawaiian islands. Using remotely sensed imagery to map physical and biological patterns in the marine environment enhances our ability to understand how environmental conditions change over broad spatial scales (10s to 100s of kilometers) and temporal scales (years to decades). These...

Dual-head Mapping
A dual-mount multibeam sonar installation is used to conduct extreme shallow-water surveys of intertidal seafloor to track morphologic change. This article contributed to by Heather Weiner, Brent von Twistern, Mike Brissette, Jonathan Beaudoin, and Amanda Hacking. The intertidal and nearshore zone is among the most ecologically productive and important zones to coastal resource management agencies. However,...
