Ocean colour signature of climate change
Nature ^ | 04 February 2019 | Stephanie Dutkiewicz, Anna E. Hickman

Monitoring changes in marine phytoplankton is important as they form the foundation of the marine food web and are crucial in the carbon cycle.

However, satellite sensors do not measure Chl-a directly. Instead, Chl-a is estimated from remote sensing reflectance (RRS): the ratio of upwelling radiance to the downwelling irradiance at the ocean’s surface. Using a model, we show that RRS in the blue-green spectrum is likely to have a stronger and earlier climate-change-driven signal than Chl-a. This is because RRS has lower natural variability and integrates not only changes to in-water Chl-a, but also alterations in other optically important constituents. Phytoplankton community structure, which strongly affects ocean optics, is likely to show one of the clearest and most rapid signatures of changes to the base of the marine ecosystem.

As oceans get warmer because of man-made global warming they will appear more bluish.

Back in the days of the Trojan War, Homer often referred to the “wine-dark sea”.

If we raise taxes high enough, will the sea be wine-dark again?

Ah, all based on another model. A model for which none of will see the code, and know how it handles the data that is fed into it.

I have poster from the early 1980s that is a NASA photo of the Earth. The oceans look pretty darned blue in that photo. I guess that the seas will be just a bit bluer. The Horror.

Maybe the snowmobilers should take their machines out in the ocean.

They could call them “Personal Watercraft” or something.

Churn up the water like blenders.

They could go across the ocean to England and eat some of their tiny taters.

Have they seen the putrid color San Antonio, TX dies their river for the tourist trade?

Right.
"Model".
"Likely".

These people are just blowing smoke.

Science of today: Let's find something, anything, that *could* be caused by climate change so we can get us some grant money.

More vivid blues and verdant greens - sounds like a camera commercial....

Call me when the oceans turns iron (II) green, like in the old days. Then I’ll be concerned.

More ocean plants would absorb more CO2.

I have the feeling that WHATEVER the color change is it will mean ‘global warming’. We know how the shysters work things...

My whitewalls will get bluer due to climate change.

All sensors use models. There are models for the sensor and models for the surface being sensed. All sensors and sensor models have error. The error factor is always there and unknown, because if the error was known it would be compensated for. The error ‘probability’ is larger for a larger size of the area being looked at. What are the odds that all of this so-called ‘change’ is within the margins of error?
