Eggleston, and K.J. Vranes. In press 2013. Is an Epic Pluvial Masking the Water Insecurity of the Greater New York City Region? Journal of Climate, Early Online Release 2012 doi: http://dx.doi.org/10.1175/JCLI-D-11-00723.1 Notes: This collection of QU subgenera Leucobalanus raw ring widths was made by E. Cook, primarily, and N. Pederson in and around the greater Albany, NY region from historical timbers and structures. Many of the samples are likely Quercus alba, but there could be some Q. montana (formerly Q. prinus) in this collection. We cannot say anything about forest conditions from which these samples originally grew. However, there are growth release patterns in some series that are similar to those seen in trees from dense forest. Therefore, it might be useful to consider detrending these raw data with closed-canopy or forest interior conditions in mind.
