Why scientists are counting tiny marine creatures, from Space

Scientists are using satellite data to monitor the abundance of tiny marine creatures called phytoplankton in the Southern Ocean around Antarctica. Phytoplankton are microscopic plants that form the base of the marine food chain and play a crucial role in regulating the Earth's climate by absorbing carbon dioxide and producing oxygen. Researchers have observed that changes in the color of the ocean can indicate shifts in the population of phytoplankton. Satellite images can detect these subtle color variations, allowing scientists to track the health and distribution of phytoplankton over large areas. This research is particularly important in the Antarctic region, where climate change is having a significant impact on the delicate marine ecosystem. By monitoring the phytoplankton population, scientists can gain insights into the broader effects of global warming on the region and inform conservation efforts to protect these vital organisms.
