Re: Color of the ocean under Noachian

The liquid ocean, under period of Noachian and Hesperian, is not a pure water but it is acid. What is chemically color of the ocean? Blue or Green of the acid water?

Re: Color of the ocean under Noachian

Hi PeterC, welcome to New Mars.

In the Noachian period, the water was alkaline, like early Earth.  Lots of clay was deposited.

But in the Hesperian period, the water was acid.  Then the ocean was a wonderful turquoise ...

Re: Color of the ocean under Noachian

noosfractual,

I believe the green color on Earth was the oxidation of Iron elements in the water. This occurred as oxygen levels increased in response to photogenic process.

I am way over my head here. Is this correct? If so then what is the acidic connection?

Re: Color of the ocean under Noachian

It depends on which chemical elements are in structure of this acid. It can be green, yellow or transparent
