By 2100, oceans would become more greener and bluer

Climate change will even change the color of the oceans, study says

Dutkiewicz fed satellite measurements of reflected light into a computer model, and correlated it to the number and type of ocean organisms.

The ocean will not look the same color in the future. Thus, more quantity of phytoplankton, lesser the blue color in the sea and more of green shaded water.

And so, as our planet continues to warm, our oceans will turn deeper shades of blue and green, according to research published Monday in the journal Nature Communications.

Mayotte, an archipelago in the Indian Ocean. Their model can estimate wavelengths of light that are absorbed and reflected by the ocean, which obviously changes by a given region and the organisms in the water.

"Phytoplankton are the base of the food web-less phytoplankton [means] less food for the rest of the marine ecosystem", study co-author Stephanie Dutkiewicz, a principal research scientist in MIT's Department of Earth, Atmospheric, and Planetary Sciences, told CTVNews.ca in an email.

From an NC State perspective, it's the fewest amount of points since the Wolfpack beat Duke 12-10 in the 1968 ACC tournament. Guard Braxton Beverly epitomized the effort for the Wolfpack with a 0-for-12 shooting performance.

The creatures' growth is dependent on how much sunlight, carbon dioxide and nutrients are around.

But phytoplankton are vulnerable to the ocean's current warming trend.

According to the computer model developed by MIT scientists, this will make the water near the poles a weirdly odd tropical green, as phytoplankton invade these territories thanks to the higher temperature conditions ideal for their reproduction.

Phytoplankton is an important element in the oceans.

What gives oceans their colour?

Dutkiewicz and her team built a climate model that projects changes to the oceans, including their optical properties, throughout the century.

Our world's oceans are in trouble there is no doubt about that. Those areas will become even bluer than they are today.

By the year 2100, they say more than 50 percent of our oceans will have shifted in color, and those regions in the subtropics and near the equator and poles will have brighter blues and deeper greens most visible through satellite images of the Earth. This change could have consequences, for example for fisheries and also on the ability of the ocean to take up carbon dioxide.

The researchers point out that the changes are an indirect impact of climate change, as warming is affecting the circulation of the seas, this is changing the amount of food available for phytoplankton. They are home to a stunning range of lifeforms of all shapes and sizes, all of which have unique properties and reflect different wavelengths of light.

Writing in the journal Nature Communications, Hickman and colleagues from the United Kingdom and USA report how they came to their conclusions by using a computer model that predicts how factors such as temperature, ocean currents and ocean acidity affects the growth and types of phytoplankton in the water, as well as levels of other coloured organic matter and detritus. "Everything in the ocean requires phytoplankton to exist".

"It's an important variable that we should be tracking to understand changes in the ocean as a result of climate change".

And why does that matter? "Different types of phytoplankton absorb light differently, and if climate change shifts one community of phytoplankton to another, that will also change the types of food webs they can support".
