The Mississippi delta region has been sinking for some time now.  Apparently there are two main factors:  (1) because of upstream flood control projects far less silt is being deposited to build the delta up  (2) subsidence of the area, attributed to the pumping of submarine oil.

Two 23.
Thank you for explaining marsh loss. I would only add that the oil company canals that allow salt water to burn the grasses is another main principal factor.
To make an account of this world disappearing one acre every hour, I'll keep going there with my camera.

A lot seems to be happening in the alluvial fan as the river goes into the Gulf.  Fertilizer run off from farms all the way up river  has created a "dead zone" in the offshore ocean.

Yes.
And similar to the anaerobic conditions of the Chesapeake Bay.

The water temperature, exchange and flow charts, and data provide the almost and exact mirror image of the painting in motion before our very eyes, not in centuries, but months of the year.

Patricia.
Thank you for your comment.
What an interesting view of this foto. Compelling and unexpected, both.
Somehow, does it read to you like a graph ?
