Our CoRPS (Collaborative Research on Paleoenvironments and Societies) group research on paleoflooding and in the Tennessee River valley was recently featured on the UA News. UA Researchers use nature to discover how waterways behaved before recorded history
Really excited to have been a part of new paper by UA grad student (and CoRPS member) Ray Lombardi in “The Holocene” on paleoflooding. “This paper presents the first meta-analysis of fluvial reconstructions focused on regional watersheds of the eastern United States,…”
Went to the Mobile Delta to sample baldcypress. Had to use the chainsaw on a few dead standing trees. This one began growing in the 1820s and died in the 1980s.
Recently visited the Paint Rock Forest Research Center and found it to be truly amazing. The variety of trees there is astounding, and the research being carried out on the forest is world class. I am looking forward to hopefully returning and doing some dendrochronology.
Interesting story in the Washington Post about infrastructure and flooding on the Mississippi River.
Met up with fellow dendro folks Grant Harley from Southern Miss and Clay Tucker from LSU (and others) to core bald cypress on the lower Pascagoula River to study streamflow. We also found a lot of nice overcup oak.
Went down to Bruce, Florida with Civil Eng. colleague G. Tootle as well as a great group of Environmental Science and CE students to core bald cypress trees to support a reconstruction of Choctawhatchee River streamflow. We were updating an earlier collection by D. Stahle as well as collecting some fantastic subfossil samples some of which may be thousands of years old. We have a nascent web site devoted to the project here http://choctawhatcheerivertreeringstudy.weebly.com/
Had a great time last week with Matt Meko collecting tree-ring samples in Illinois from sites sampled by D. Duvick in 1980. We were joined at Ferne Clyffe St. Park by Justin Maxwell and his crew and and Kankakee St. Park and Starved Rock St. Park by Emma Bialecki (@emmabialecki). We saw some great old growth oak forest though there was a lot of invasive species in some areas. The highlight of the trip for me was sampling at Starved […]
The mfecane is thought to be a massive upheaval and devastation of Nguni tribal chiefdoms in the second decade of the 19th century in what is now KwaZulu-Natal and the Eastern Cape of South Africa. We show that pervasive cycles of drought and cold periods in southern Africa are significantly amplified and extended by volcanic eruptions and that, in particular, the eruption of Tambora in 1815 triggered a prolonged and extreme climatic event which bears all of the characteristics ascribed […]
