Satellite Detects Red Glow To Map Global Ocean Plant Health

Plankton ... så småt og så aligevel så stort når blot at der er mange nok ... En stor del af jordens biomasse er bundet i plankton så det er nok en god ide at holde et skarpt øje med tilstanden disse små kræ ...

Plankton ... so small and yet so big when all combined ... A large amount of the earth bio mass is contained within these small creatures and keeping an eye on their well being might be a good idea ...


Researchers from Oregon State University, NASA and other organizations said today that they have succeeded for the first time in measuring the physiology of marine phytoplankton through satellite measurements of its fluorescence – an accomplishment that had been elusive for years.

With this new tool and the continued use of the MODIS Aqua satellite, scientists will now be able to gain a reasonably accurate picture of the ocean's health and productivity about every week, all over the planet.

Data such as this will be critically important in evaluating the effect on oceans of global warming, climate change, desertification and other changes, the researchers said. It will also be a key to determining which areas of the ocean are limited in their productivity by iron deficiency – as this study just showed the Indian Ocean was. [...]
