Shemesh, A., and D. Peteet, 1998: Oxygen isotopes in fresh water biogenic opal — Northeastern US Alleröd-Younger Dryas temperature shift. Geophys. Res. Lett., 25, 1935-1938, doi:10.1029/98GL01443.

The first oxygen isotope analysis of biogenic opal from lake sediments, from the Alleröd/Younger Dryas transition in a core from Linsley Pond, Connecticut, gives an average estimate of a 6°C drop in temperature during the Younger Dryas. This shift represents temperatures during the bloom season, and may be less than the winter temperature drop. The sharp transition itself, with a duration of about 200 years, suggests that the tmperature decrease may have been as large as 12°C. Previous estimates of the Alleröd/Younger Dryas temperature shifts are controversial, and range from 3-20°C, suggesting that further interdisciplinary research on the same samples is warranted.
