Satellite passive ocean color instruments have provided an unbroken ∼20-year record of global ocean plankton properties, but this measurement approach has inherent limitations in terms of spatial-temporal sampling and ability to resolve vertical structure within the water column. These limitations can be addressed by coupling ocean color data with measurements from a spaceborne lidar. Airborne lidars have been used for decades to study ocean subsurface properties, but recent breakthroughs have now demonstrated that plankton properties can be measured with a satellite lidar. The satellite lidar era in oceanography has arrived. Here, we present a review of the lidar technique, its applications in marine systems, a perspective on what can be accomplished in the near future with an ocean- and atmosphere-optimized satellite lidar, and a vision for a multiplatform virtual constellation of observational assets that would enable a three-dimensional reconstruction of global ocean ecosystems.

海洋系统研究中的星载激光雷达。
卫星无源海洋彩色仪器已经提供了约20年的全球海洋浮游生物特性的连续记录,但是这种测量方法在时空采样和解析水柱内垂直结构的能力方面存在固有的局限性。这些局限性可以通过将海洋颜色数据与星载激光雷达的测量结果结合起来解决。几十年来,机载激光雷达一直用于研究海洋的地下属性,但最近的突破表明,可以使用卫星激光雷达来测量浮游生物的属性。海洋学的卫星激光雷达时代已经到来。在这里,我们对激光雷达技术及其在海洋系统中的应用进行了综述,并展望了在不久的将来使用海洋和大气优化的卫星激光雷达可以完成的工作,
