“Reconstructing Northeastern United States temperatures using Atlantic white cedar tree rings” is out!

At long last, our paper showing skillful reconstructions of Northeastern temperatures using Atlantic white cedar tree-rings has been published! You can access it here: https://doi.org/10.1088/1748-9326/aa8f1b

Past Global Changes Youth Science Meeting in Morillo de Tou, Spain

This past weekend I had to privilege to be amongst some 90 young scientists from across the world who study all aspects past global changes, and how the knowledge we produce will help aid our understanding of the current, and future, Earth systems. It was held in a small, refurbished village in the foothills of the Pyrenees with gorgeous views of snow-capped peaks, glacier fed rivers, and lush forests. It was wonderful reminder of how incredible the Earth is, and how lucky I am to be a scientist! We participated in workshops that helped us become better communicators, shape the next ten years of paleo-science, and identity the scientific needs of at-risk communities and societies in the coming era of rapid global change.

 

It was great to be re-invigorated on my science, and has gotten (I believe) all those who attended excited for this weeks PAGES Open Science meeting (OSM) in Zaragoza, Spain!

 

The wine isn’t so bad either

UA Science Café: Climate at the core

This Thursday (2/9/17)  I will be speaking at Borderlands Brewing Company in Tucson, AZ about the use of dendrochronology in the northeastern United States and some of my newest research!

2016 Atlantic White Cedar Symposium

This year’s Atlantic White Cedar symposium in Plymouth, MA, I presented on the climate controls of AWC ring widths. It was a great opportunity for me to present my research to a wide range of AWC enthusiasts: from academics, engineers, botanists, ecologists, hydrologists and land managers. AWC is a beloved tree all along the eastern seaboard! It was wonderful to meet so many new scientists working on the same tree. I got tips on where to find some more cedar swamps, contacts with people who routinely uncover sub-fossil stumps, and discovered the cultural uses of AWC from a presentation by members of the Narragansett tribe.

Ameridendro 2016, Argentina

This year’s American Dendrochronology Conference was held in Mendoza, Argentina. This conference brings together dendrochronologists of all flavors from North, Central, and South America for talks, poster sessions, and field trips.

I was lucky enough to spend the week before the conference in El Bolson, Argentina at the “Ameridendro Fieldweek”. I have been able to learn from some of the dendrochronology greats (Dr. Ed Cook and Dr. Ricardo Villalaba) and really delve into more complex data standardization, signal processing, and climate reconstructions.

Current Project

Paleoclimate data provide the opportunity to understand the earth’s climate system on timescales from decades to millennia, as well as the frequency and magnitude of extreme events. This information cannot be robustly determined from relatively short instrumental observations alone. My research  will develop an extensive network of precisely dated and annually-resolved late Holocene tree-ring chronologies from living and preserved (subfossil) Atlantic White cedar (AWC) forests throughout the northeastern United States that will be used to determine the precise timing, frequency, and spatial pattern of past coastal New England extreme storms. These data will be used to improve and extend the climate history of New England and to identify the occurrence, frequency, and broad-scale climate context of hurricane and powerful nor’easter events. These data are a novel high-precision paleoclimate proxy that will help provide essential information about extreme events affecting the heavily populated coast of the northeastern United States.
