In response to mounting ecological pressures related to climate change and population growth, marine scientists and resource managers have increasingly turned to remote sensing as a means of providing timely and spatially coherent environmental information. Earth imaging sensor technology aboard aircraft and satellites has advanced rapidly from multispectral systems offering a small number of broad, discontiguous bands in the visible and infrared portions of the spectrum to imaging spectrometers with continuous, high-resolution coverage throughout the complete visible and near-infrared spectrum. The subject of hyperspectral remote sensing has rapidly gained momentum with the recent deployment of DESIS on the International Space Station, the launch of PRISMA, and planning for the NASA PACE and SBG sensors in response to the most recent decadal survey. NASA recently completed an airborne mission that mapped coral reefs in the tropical Pacific using PRISM, and applications have expanded to include small, lightweight systems deployable on commonly available drones, effectively placing advanced remote sensing capabilities in the hands of the individual researcher. Most recent investigations include merging the unique aspects of hyperspectral observations with other data to enhance knowledge of marine ecosystem health and biodiversity. The purpose of this session is to present and discuss the state of the art and novel application of hyperspectral remote sensing, from near-surface to space, for coastal aquatic environments. Papers are encouraged that cover all aspects of the topic including sensor development, new algorithmic approaches, emerging modes of deployment, and case studies spanning basic research to societally relevant applications.
