New research studying 20 years of ocean information has found that our oceans have changed colour. This also means a great change in the ecosystem of oceans, which is likely caused by human activities.
For tens of years, satellites have been watching the colour of the earth's oceans and collecting information on the colour of light reflecting(反射) off the water. Especially one of the satellites, the Aqua satellite has recently completed 20 years of collecting high-quality global ocean-colour information. A new study has examined this information and found changes in the ocean colour over the past 20 years, which cannot be explained by natural, year-to-year variability(可变性) alone.
"I've been running models to study the ocean colour. The models have been telling me for years that these changes in the ocean colour are going to happen," said Stephanie Dutkiewicz, one of the study's writers. "To actually see it happening for real is not surprising. But I am scared that these changes are probably caused by human activities."
The ocean's colour shows the life that lives in the water. Deep blue water usually has very little life. However, greener water means the presence of ecosystems, mainly plankton(浮游生物). Without plankton, many oceanic food webs would break down. This will greatly
impact the sea life and humans that depend on fish for food.
"The colour of our oceans has changed," said Dutkiewicz. "And we can't say how. But we can say that changes in the ocean colour show changes in plankton communities. Plankton communities are the foundation(基础) of everything that feeds on plankton. So, we hope people take this problem seriously."
Next, Dutkiewicz will try to better understand the colour changes in different ocean areas, as well as looking into what might be causing them.
