Thermodynamics. You may not realize that steam and water were the drivers of the industrial revolution. We know a lot about water in various states. If the water was in the atmosphere the temperature and pressure required to keep it there would make the Earth uninhabitable. If the water came from outside the atmosphere the heat released by loss of potential energy would make the Earth uninhabitable. Except, of course, for a few thermophilic bacteria.
Don't know if you're aware of this, but there's a lake in Sweden with 9,000-odd varves that are still forming today. As you know one of the alleged issues with Suigetsu is that the varves aren't forming today.
quote:We use statistical correlation of palaeomagnetic secular variation (PSV) curves from a varved Holocene lake sediment sequence in west central Sweden (Lake Kälksjön) against those of a Fennoscandian master stack (FENNOSTACK) to correct for an apparent error in the varve chronology. Additional correlation between a lead pollution-derived chronology for the last 2000 years corroborates the PSV results. Use of the FENNOSTACK palaeomagnetic master curve reveals no significant difference in duration between large-scale features from ∼2500 to ∼8000 cal. yrs BP. Statistical correlation, however, implies that 270 years are missing from the younger part (8000 cal. yrs BP). A similar comparison between the PSV-determined ages and calibrated bulk radiocarbon ages suggests that the sediments of mid-Holocene age contain substantial amounts of old carbon, probably of soil origin, which causes bulk sediment-calibrated mean 14C ages to be up to 850 years older than the corrected varve chronology, which extends to 9193 ± 186 cal. yrs BP. This study highlights both the use of statistical correlation as a technique for detecting errors between chronologies, and the importance of validating incremental chronologies with more than one independent method.
