This is great, and I hope it get's opensourced and more widespread. One thing of ecological importance that could be emphasized more, is that the shell of shell-fish represents a stable carbon sink. It's not so much that sea-gras extracts more anorganic carbon than land plants, because that organic carbon is likely going to end up as CO2 one way or another. But shells allow to effectively remove excessive carbon from the global carbon cycle.
