Gridplates global sediment circulation model

• March 15, Worked on ocean sedimentation, to try to create more continental rise at the margins. There is a new Laurentia elevation transect animation, and a slice-by-slice comparison of the model end state with observed elevation and sediment thickness. Concentrated sedimentation near the margin by decreasing the ocean sediment transport coefficient by 2 orders of magnitude.
• March 10, Increased Paleozoic sea level rise to 400 meters, which increased the thickness of the CaCO3 on continents to 1.5 km, which is still not enough but proof of concept. Came up with a scheme to only allow ocean-to-continent grid point transitions while limiting the 'land-spreading' in the last simulation.
• March 5, eliminated land sediment transport of CaCO3, turned off continent to ocean transitions. Now the sea floor looks less lumpy near the coasts but the continents get all raggedy because grid points flip to continent randomly at the edges and never flip back.
• February 20, fixed isostacy again to get mid ocean ridge depths right. Next goal is to get more CaCO3 on continents and keep it there.
• February 16, sea level now changes as instructed.
• February 15, fixed problems in isostacy but sea level change was not being applied.
• February 13, turned off subaereal CaCO3 dissolution to see if that's where it was disappearing to.
• February 12, Fixed a problem with subaereal sediment dissolution going below sea level. Doh!
• February 9, Fixed the clay bug and some other problems. Weathering and erosion fluxes are probably wrong, need to be checked.
• February 7, First results with altitude tracking the Scotese reconstruction (realigned to the Merdith plate locations), and ice sheets, parameterized as locations where climate model results make it -10 deg. C or colder. There are problems with the chemical vs physical weathering in this simulation
• January 24, First results with altitude tracking the Scotese reconstruction (realigned to the Merdith plate locations), and ice sheets, parameterized as locations where climate model results make it -10 deg. C or colder. There was a bug, no clay production on land, so everywhere is flooded. n
• December 11, The continental crust now thins after orography to minimize secular trend in crust thickness. Land and ocean sediment loads now approximately correct.
• December 9, CaCO3 burial at a specified rate, trying to increase land sediment thickness by not letting the crust get too thick
• December 6, Ca-conserving run, choked for CaCO3
