description: Estimates of future flood risks are based on the observations of past floods, but instrumental records of basin hydrology are often too short to assess potential changes in the frequency or magnitude of extreme floods over time. In this study, we show that bur oak (Quercus macrocarpa Michx.) growing along the Red River of the North in North Dakota and Minnesota preserve evidence of past floods within their annual growth rings. Rings formed during major floods often displayed (i) marked reductions in the size of their earlywood vessels or (ii) a more diffuse distribution of vessels throughout the increment. Because of the correspondence between major floods and widespread anatomical anomalies within riparian oaks, we suggest that these features can be described as "flood rings." The frequency of flood-ring formation varied substantially along the river, which implies that this evidence can only provide an accurate estimate of flood history when it is obtained from many trees sampled across a dense network of sites. The rate of flood-ring formation is primarily influenced by flood magnitude but is also controlled by the timing and duration of inundation relative to the period of cambial growth. Although flood-affected oaks are imperfect recorders of past floods, this approach offers significant potential as a means to estimate the preinstrumental flood history of the Red River within the United States.

description: Ring-width chronologies have been developed for alpine larch (Larixlyallii Pari.) at six tree-line sites in the Banff-Kananaskis area of the southern Canadian Rockies. Evaluation of all chronologies confirms that alpine larch ring-width series have higher mean sensitivities, lower autocorrelation, and greater common variance than series from other tree species growing at tree line in this area. Missing and very narrow rings created cross-dating difficulties at all sites but were most problematic for the sites along the Continental Divide. Up to 1% of the rings were missing from entire chronologies, but for specific years, up to 77% of the rings were missing at one site. Marker (narrow) rings were present at all sites for the years 1610, 1654, 1715, 1720, 1723, 1752, 1799, 1824, 1842, 1844, 1915, 1925, 1951, and 1971. Tree growth rates were reduced for the periods 1675-1710, 1815-1850, and 1960-1978 whereas increased growth occurred during 1650-1680, 1750-1800, 1850-1900, and 1920-1950. The only factor that could affect all sites over such a broad geographic area is climate. Principal components analysis indicated that the first eigenvector derived from the six chronologies accounted for 70.7% of their common variance and the first three components accounted for 91.6%. The high correlation between the six first principal component and standard chronologies suggested that either method may be used for standardizing tree-ring data from alpine larch.

title: NOAA/WDS Paleoclimatology - Lake Mina, Minnesota 900yr Pollen-inferred Temperature and Moisture

description: Drought is endemic to the North American Great Plains, causing severe economic consequences. However, instrumental climate data only exist from ca AD 1890, and limited tree-ring, paleolimnological, archeological and eolian records document the last two millennia. To address this lack of monitoring and paleoclimatic data, the pollen preserved in the varved sediments of Lake Mina, Minnesota, on the northeastern border of the Great Plains, were analyzed. May and February mean monthly temperatures and "annual precipitation minus potential evapotranspiration" were reconstructed at a 4-year resolution using a pre-settlement pollen-climate calibration set. The period of the so-called Little Ice Age (LIA) (AD 1500-1870) was colder than the Medieval Climate Anomaly (MCA) (AD 1100-1500) in west-central Minnesota. Winter temperatures in the LIA declined more than summer ones. The pollen record suggests that the LIA occurred in three phases: an initial cold phase from AD 1505 to AD 1575, a warmer phase, and then a very cold phase from AD 1625 to AD 1775. There were severe droughts detected in the Lake Mina record from AD 1660 to AD 1710 and AD 1300 to AD 1400, suggesting that high-resolution pollen records can detect events previously defined from the tree-ring records. This latter century-scale drought is concurrent with the widely reported "AD 1250-1400 mega-drought", which exceeds the severity of 20th century droughts.
description: Pollen data and inferred temperature and moisture balance reconstructions from Lake Mina, Minnesota, USA.  The analyzed and published portion of the core spans AD 1116-2002. Most of it was sampled at a 4-year resolution, the very top (1952-2002) is at ~2-year resolution.  Comparison to Platt Bradbury's Elk Lake varve-dated core is excellent: The 1300s megadrought at Lake Mina is at AD 1304-1396, the Elk Lake megadrought is at AD 1284-1409, using different proxies. The reconstruction is not reliable after 1876 AD, due to human disturbance.  The winter and summer temperature pollen reconstructions were validated using early military fort instrumental climate data for 1820-1876.  Varve chronology corroborated by exotic pollen introductions and a bottom radiocarbon date.

description: A new network of 21 Picea engelmannii Parry ex Engelm. ring-width chronologies was developed from tree-line sites in the Canadian Rockies. These chronologies range in length from 297 to 648 years (mean 423 years) and have mean sensitivities between 0.16 and 0.20 (mean 0.18), first-order autocorrelations between 0.73 and 0.88 (mean 0.83), and subsample signal strengths >0.85 for 246-494 years (mean 324 years). Mean intersite correlations (A.D. 1700-1982) for chronologies with expressed population signals >0.85 are 0.46 and 0.63 for standard and residual chronologies, respectively. Standard ring-width chronologies are, in general, positively correlated with summer temperatures and negatively correlated with spring and previous summer temperatures. A regional June-September temperature reconstruction for the Banff-Jasper region (BJR; A.D. 1715-1982) was developed using multiple regression of three significant principal components from 14 standard ring-width chronologies. The first principal component contains 55% of the total chronology variance. The model reconstructs 38% of summer temperature variance during the calibration period (1888-1982). The BJR is the first regional temperature reconstruction for this area based on ring-width data from a network of sites. The reconstructed temperature patterns are broadly similar to other regional estimates of past temperatures. Above-average summer temperatures occurred in the mid-20th century and the late 1700s - early 1800s. Most of the 19th century was unusually cold, with the coldest conditions in the late 19th century. Detailed differences between BJR and previously developed reconstructions lie well within 2 sigma confidence limits and may reflect differences in tree species, modelling techniques, spatial coverage, and the seasonal temperature parameter reconstructed.
