NASA Satellites Can detection Phytoplankton Growth

WASHINGTON - For scientists first do an analysis on the global health and productivity of marine plants, using the unique signal detected Satellites belonging to NASA Aqua. With technology Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA property Aqua Satellites, scientists can now observe a red light heating of phytoplankton that appear on the surface of the sea. MODIS is the first device that can observe a red light signal is in global scale. This is easier for researchers to do research from the remote marine with the number of heating the red light emanated phytoplankton. They can gauge how efficiently plants mikroskopik this change sunlight into food through photosynthesis. People's Daily Online, Friday (29/5/2009) spread, Phytoplankton bersel one that meets the sea's ecosystem, is the primary food source for marine animals. Plants, this half of the photosynthesis activity on land, and play an important role in the balance of carbon dioxide in the atmosphere of the earth. Thus, if phytoplankton can grow with a fertile and healthy, this will affect the amount of carbon dioxide that can be absorbed from the atmosphere. By doing so, the more clearly that the sea is not less important role in climate change issues. "Engineering is using the satellite is the first method that can measure the level of health and productivity of phytoplankton in the sea," said Michael Behrenfeld, biologist from Oregon State University. "Luckily we have a new device that is very important to monitor the development of phytoplankton in the world, each pekannya," he added. Previously, scientists using satellite sensors to track the number of plants that live on the sea floor to measure the amount and distribution of content or substance klorofil green leaves.
