I put in today more out of urgency than want. Sometimes, I fear the passing of the day or seasons without being able to see the changes. The spring migration is on, and what is in the marsh changes with each day. I also know that all of this may change all too soon, that I may be one of the last to experience the spartina marsh. New research suggests faster rising ocean levels than were previously predicted. This is not a surprise to me. I am an engineer and I know just enough about mathematical systems modeling to know that unexpected intricacies can make major differences. Modeling nature is a supremely difficult task.
Spartina marshes hover right at the top of high tide. The annual growth of grasses die and compost themselves into the marsh, building height at about the same rate that the marsh compacts and loses that gain. When I look at old maps, I find that the spartina is remarkably stable, islands in the rivers have changed little in shape over the last 125 years. I expect that a rapid rise in ocean level will upset the delicate balance.
The take out is mud now. I slide the canoe over the greasy surface, my boots going in about 8 inches, but not sticking as long as I keep moving. I have washing to do.
