Solid-phase parameters include sand-sized charcoal counts, total carbon (TC), total inorganic carbon (TIC), total organic carbon (TOC), bulk stable carbon 13\/12 isotope ratios (d13C), bulk stable nitrogen 15\/14 isotope ratios (d15N), and concentrations of 60 elements in the less than 63 micron fine fraction.",

Assessments include evaluations of present ecological or economic values of substrate distributions, drivers of substrate change, and functions of substrates. Predictions are the results of models or projections of future substrate distributions, values, or ecological impacts, including predicted substrate changes due to natural and human forces including erosion, accretion, sea-level change, extraction, trawling, or other factors; and they are the results of scenario-based models of substrate changes on ecological or economic values under different management strategies or other human alterations."
