oceans The lands are changing color at an alarming rate. This color change is caused by a number of factors, including climate change, pollution, and overfishing.
All this was reviewed for 20 years by a group of researchers who reviewed data from the MODIS-Aqua satellite.
Climate change is causing the oceans to warm up and become more acidic. This kills corals, which are the main producers of oxygen in the oceans. Corals are also home to a wide variety of marine life, and their loss has a devastating effect on marine biodiversity.
This faster change is due to remote sensing reflectivity, which refers to images of ocean color based on reflected light. Processing these images is somewhat easier than trying to measure phytoplankton populations using other methods such as chlorophyll estimation.
“Remote sensing reflectivity, and thus ocean surface ecology, has changed significantly over much of the ocean over the past 20 years,” the researchers write in their paper published in the journal Nature.
Pollution also contributes to changing the color of the oceans. Chemical and plastic waste is polluting the oceans and killing fish and other sea creatures. It also blocks sunlight, which affects the growth of marine plants.
“Taken together, these results indicate that the effects of climate change are already being felt in surface marine microbial ecosystems, but have yet to be detected,” the researchers comment.
