Kudos to Matthew Trumper, a UMN Geography B.S. student, who has received a prestigious NOAA Summer Fellowship for 2019.

Matthew will participate in the Great Lakes Summer Fellows Program at NOAA’s Great Lakes Environmental Research Lab (GLERL) in Ann Arbor, MI. "Through this program, students work on substantive research issues in the Great Lakes and undergo a career training program that equips them with the knowledge and skills to be the next generation of Great Lakes scientists”. Specifically, he will be working with Dr. Jia Wang, Dr. Hongyan Zhang and Dr. James Kessler looking at Great Lakes Ice Climate and its Impacts on the Water Quality of Lake Erie.

This exceptional opportunity is well timed for Matthew, who will graduate in May with a B.S. in Geography summa cm laude, plus a minor in statistics. Matthew has already developed a remarkable curriculum vitae that includes two UMN UROP awards, a National Science Foundation (NSF) Research Experience for the Undergraduate (REU) award, and a 2018 outstanding paper award from the West Lakes. In two weeks time, he will defend his senior honors thesis on research with tree-rings and experimental nitrogen cycle dynamics at the Cedar Creek Ecosystem Science Reserve. Since his freshman year, Matthew has a been a stand out member of our department’s undergraduate and research communities. This award is very well deserved. Congratulations!

Congratulations to Liam Martin who successfully defended his MA Thesis in Geography this week! His thesis examined fire history along three sites along the Bois Brule River in N. Wisconsin. The area was an important place for the Ojibwe and other travelers, with the Brule serving as a critical link between the St. Croix and Mississippi Rivers and Lake Superior. Nice job, Liam!

We're so pleased to welcome Dr. Farid Seyfullayev as a visiting scientist with the Dendro Center this autumn.

Dr. Seyfullayev, who works with the Azerbaijan National Academy of Science's Central Botanical Garden in Baku, was awarded a grant by the US Fulbright to support his visit to Minneapolis. During his stay, Dr. Seyfullayev will study how climate influences the growth of oak forests in Azerbaijan.

Welcome to Minnesota Farid!

We're seeking an MA/PhD student to join an NSF-funded project on extreme paleofloods in the Red River of the North. The position includes academic year and summer funding, plus training opportunities with collaborators at the Swiss Federal Institute for Forest, Snow and Landscape Research and the USGS Dakota Water Center.

Please visit the link or contact Scott St. George ([email protected]) for more information.

I’m seeking to recruit a graduate student (beginning Fall 2019) to join an NSF-funded project on extreme paleofloods on the northern Great Plains. This position, which will be co-supervised by me and Dr. Joe Zeleznik (North Dakota State University), will combine methods from dendrochronology,...

Kurt and two grad assistants managed to make it out to Stockton Island for some field sampling and inventory in a coastal red pine barrens. Beautiful site. Thankful for the phenomenal boat driving ability and hospitality of NPS personnel.

During the first half of the second millennium, the American West was plagued by a succession of decades-long dry spells. Could it happen again?

We're of Dendro Center alum Erika Eidson, who led a new study demonstrating that Great Basin bristlecone pines are uniquely resilient to mountain pine beetles. It's an important contribution, and we're so proud of Erika and all her successes since graduating from our group.

What have tree rings told us about Northern Hemisphere temperatures during the past millennia? A new paper by a team of German, American, Swedish, Swiss, and British scientists, including Scott St. George, reviews what we’ve learned from tree rings as paleothermometers and recommends ways we might improve our understanding of climate change during the last thousand years.

Over the past two decades, the dendroclimate community has produced various annually resolved, warm season temperature reconstructions for the extratropical Northern Hemisphere. Here we compare these tree-ring based reconstructions back to 831 CE and present a set of basic metrics to provide guidanc...
