PhD student Chi Chen co-authors article on 2015/16 ENSO event impacts to the carbon cycle

October 22nd, 2018 in 2018, Faculty, Graduate students, Oct-18, Ranga Myneni

PhD student Chi Chen (advised by Ranga Myneni) contributed to a recently published article on the impacts of 2015/16 El Niño event to the terrestrial Carbon cycle. In “Impact of the 2015/2016 El Niño on the terrestrial carbon cycle constrained by bottom-up and top-down approaches,” published in Philosophical Transactions of the Royal Society, Chen and his colleagues note this major event imposed extreme warming and dryness in the tropics and other sensitive regions causing a significant perturbation to the global carbon cycle.

E&E major Emma Quirk rows for BU

October 18th, 2018 in 2018, Oct-18, Undergraduate

Emma Quirk, an Earth & Environmental Science major and senior, joins the Head of the Charles Regatta this weekend with BU’s Rowing Team. The event attracts more than 11,000 athletes competing in more than 1,900 boats in 53 races and is the largest two-day regatta in the world. The competition attracts tens of thousands of spectators to the banks of the Charles River each year. Go Terriers!

John Fegyveresi publishes on ice core bubbles as strain indicators

October 16th, 2018 in 2018, Faculty, News, Oct-18, Pub-18, Publications

Adjunct Assistant Professor John Fegyveresi and his colleagues have penned “Instruments and methods: a case study of ice core bubbles as strain indicators” in Annals of Glaciology. In their abstract, the authors note, “Measurements of a sample from ~580 m depth in the WAIS Divide (WDC06A) ice core reveal that bubbles are preferentially elongated in the basal plane of their parent grain, as expected if bubble shape preserves the record of dominant basal glide. This suggests that a method using bubbles as strain gauges could provide insights to grain-scale ice deformation. We introduce a technique using fabric and image analyses of paired thin and thick sections.”

Professor Rick Murray has been elected to a two-year term as a member of the Board of Directors of the American Geophysical Association, where he will help oversee AGU’s business, organizational, and legal affairs. For nearly a century AGU has worked to promote discovery in Earth and space science for the benefit of humanity.

Dan Li publishes on atmospheric boundary layer in Atmospheric Research

October 11th, 2018 in 2018, Dan Li, Faculty, News, Oct-18, Pub-18, Publications

Assistant Professor Dan Li has published a single-author, invited review article titled “Turbulent Prandtl number in the atmospheric boundary layer – where are we now?” in Atmospheric Research. Turbulent Prandtl number is named after the Father of Modern Fluid Mechanics, Ludwig Prandtl, and is an indicator of how turbulent transport of heat differs from its counterpart of momentum. It is a key parameter in first-order turbulence closure schemes used in weather and climate models. In this article, Professor Li reviews recent advances in understanding and modeling of turbulent Prandtl number in the atmospheric boundary layer and presented a unifying framework for turbulent Prandtl number based on his own recent work.

Istem Fer, Elizabeth Cowdery, and Mike Dietze publish in Biogeosciences

October 4th, 2018 in 2018, Faculty, Graduate students, Michael Dietze, News, Oct-18, Pub-18, Publications, Researchers

Postdoc Istem Fer, PhD candidate Elizabeth Cowdery, and Associate Professor Mike Dietze have co-authored “Linking big models to big data: efficient ecosystem model calibration through Bayesian model emulation” in Biogeosciences. “Bayesian methods provide a rigorous data assimilation framework for these applications, especially for problems with multiple data constraints,” the authors note. “However, the Markov chain Monte Carlo (MCMC) techniques underlying most Bayesian calibration can be prohibitive for computationally demanding models and large datasets. We employ an alternative method, Bayesian model emulation of sufficient statistics, that can approximate the full joint posterior density, is more amenable to parallelization, and provides an estimate of parameter sensitivity.”

Wally Fulweiler to speak about discovering the unknown at Radcliffe Institute

September 26th, 2018 in 2018, Events, Faculty, News, Oct-18, Presentations, Robinson "Wally" Fulweiler, Talks

Associate Professor Wally Fulweiler will join The Undiscovered, a Radcliffe Institute science symposium that will focus on how scientists explore realities they cannot anticipate. Speakers from across the disciplines of modern science will present personal experiences and discuss how to train scientists, educators, and funders to foster the expertise and open-mindedness needed to reveal undiscovered aspects of the world around us.

Friday, October 26, 9 AM–5 PM

Knafel Center
10 Garden Street
Cambridge, MA 02138

To paraphrase Louis Pasteur, sometimes luck favors the prepared mind, as when Alexander Fleming discovered penicillin by noticing that mold growing accidentally in his lab seemed to kill bacteria. At other times, new instruments offer unanticipated revelations: Galileo trained his telescope on Jupiter and found it to have moons. And, occasionally, methodical experiments find exactly the opposite of what they sought to prove. Scientists intending to measure the deceleration of the Universe’s expansion, for example, found acceleration instead.
