Researchers have conducted the first global analysis of the health and productivity of ocean plants using a unique signal detected by NASA’s Aqua satellite. Ocean scientists can now remotely measure the amount of fluorescent red light emitted by phytoplankton and assess how efficiently these microscopic plants turn sunlight and nutrients into food through photosynthesis. Researchers [...]
