We wrapped up the last day with age-depth models and independent project presentations.

\n3 classical age models include linear interpolation (connect the dots), regression (linear or polynomial), and smooth spline. If you use classical age models,\u00a0CLAM<\/a> (classical age models) is an R package that is good step forward.<\/p>\n

The field is moving away from classical models and starting to use Bayesian Age Models (started in the mid-1990s). The age model we discussed and applied to actual data is BACON<\/a>.<\/p>\n

Here is an example of the age model example the class walked through for sediment collected from Glimmerglass Lake. It is a nice example of a model that is well mixed, fits well, and goes through all radiocarbon dates.<\/p>\n

The afternoon was dedicated to student presentations on their independent projects. There were a wide range of independent project topics including:<\/p>\n

    \n
  1. State space model for plant macrofossils<\/li>\n
  2. Quantify variance between lake pollen loadings using observed pollen proportions<\/li>\n
  3. 2000 years of inferred forest structure in the southern Sierra Nevada from a wet meadow<\/li>\n
  4. Empirical succession model application to the fading record problem and uncertainty in forest density trajectories<\/li>\n
  5. Using pollen and squirrel fossils to explore two datasets with irregular spacing of time<\/li>\n
  6. Exploring Colombian vegetation using 4 proxies: 13C, volcanic minerals, archaeological artifacts and charcoal<\/li>\n
  7. Fire signals in southern CA<\/li>\n
  8. Pollen in Australian lakes<\/li>\n
  9. MCMC of Alaska Picea glauca<\/em> (white spruce)<\/li>\n
  10. Detecting dust storms in lake sediment cores – are the dust storms increasing?<\/li>\n
  11. Using eddy flux data and terrestrial models to estimate NPP and biomass from tree rings<\/li>\n<\/ol>\n

    For only having 6 hours work, the projects turned out really well, with lots of converged iterations. It was great to see how much the students were able to pick up over the past 6 days.<\/p>\n

    We wrapped up big week with lots of hard work by celebrating with a classic Friday night fish fry dinner at Bent’s Camp<\/a>!<\/p>\n
