Technical Report 72 of the Interagency Ecological Program for the San Francisco Estuary.

High resolution climate of the past 3,500 years of coastal northernmost California

the largest age control gap is 3435 uncal yrs, accepted with relaxing criteria: important record from the region

twig with bark (excluded from age model)

Chronology gap > 3000 years, but fills important geographic region

"Here, we propose a depositional model stating that high percent clay values (or intervals of clay dominance) indicate persistent standing water wherein the deposition, accumulation, and preservation of fine- grained sediment exceeds an undefined critical thickness that inhibits deflation during succeeding desiccation events or ephemeral lake environments."

" In Silver Lake, changes in these ratios (C/N) are interpreted to reflect changes in the source of organic matter under relative perennial vs. ephemeral lake states. Perennial lakes pro- mote lake productivity producing low Corg:Ntotal ratios. Ephemeral lakes are associated with higher Corg:Ntotal ratios as the contribution of terrestrial organic matter increases in the presence of lower lake levels and the subsequent encroachment of terrestrial organics onto the playa surface.
