Big kudos to the Science Fest organizing team, led by Ian Wang and Anna Jessee, and to our faithful faculty leader, Cody Kirkpatrick! And thanks to Polly Sturgeon and her colleagues at IGS for a superb collaboration in the Earthquake Zone!

Earthquake Shakeout Drill at IU
earthquake drill

No, it’s not students overwhelmed with mid-semester academic just so happened that Dr. Michael Hamburger was teaching a class on natural disasters when IU held its first Earthquake Shakeout Drill on October 20. When the mock earthquake occurred in the middle of his class, Dr. Hamburger helped the class practice how to protect themselves to prepare for a future earthquake that will inevitably strike south-central Indiana.

Indiana University students and employees on all IU-administered campuses were encouraged to practice the appropriate response during an earthquake as part of the Great Central U.S. Shakeout on Thursday.

IU is in the proximity of the Wabash Valley and New Madrid seismic zones, making IU’s participation more than just an idle exercise. In advance of the drill, IU faculty, students and staff were asked to review the procedures (summarized at the link below) so that they could be prepared in the event of a future earthquake.

Announcing the new paleontology platform on Notes From Nature!
notes from nature

For Immediate Release: The Indiana University Paleontology Collection has partnered with Notes From Nature to create a new label transcription service specifically for fossils! Notes From Nature creates and provides infrastructure to enable collaborative efforts between research scientists and citizen scientists. This multi-faceted approach enables Indiana University researchers to grant public access to images of the incredible fossils in our collection (we’ve got over 1.5 million fossils!) but also enables interested individuals to assist in the digital data generation process (we»ve got quite the backlog….over 1.5 million fossils!) and metadata curation.

Our first transcription expedition consists of a significant collection of Cambrian trilobites casted by Charles Deiss, of Indiana University. Dr. Deiss visited many world-class institutions to make these plaster molds as perfect replicas of the fossils contained in the original museums for his research. Plaster molds were used by Dr. Deiss and other scientists in the early part of the 20th century because 3D scanning and printing didn’t exist yet! Fortunately for us, data sharing is considerably easier now and with new technology and the support of volunteers to assist in this effort to uncover the secrets of the history of life on Earth, we’re getting closer to new discoveries every day!

Michael Hamburger at National Academy of Science
Michael Hamburger

Professor Hamburger has been away from the Department for the past year, representing Indiana University in our nation’s capital.

Last spring, Hamburger was selected to take part in the National Academy of Science’s Jefferson Science Fellowship program, the first IUB faculty member to take part in this prestigious program. Each year, the fellowship brings a dozen scientists and engineers to Washington to serve as foreign policy advisors to the U.S. Department of State and the Agency for International Development. Hamburger landed an unusual posting, as a Senior Advisor in the State Department’s Office of Religion and Global Affairs. The Office, created by Secretary John Kerry in 2013, is something of a policy think-tank, focusing on the role of religious dynamics in all of the major global issues that play a role U.S. foreign policy. As the only scientist in the office, Hamburger’s work has focused on variety of global environmental issues, including climate change, public health, wildlife trafficking, and natural disasters. His office’s work with religious groups both domestically and internationally contributed to the successful negotiation of the landmark climate agreement at the COP-21 conference in Paris.

Through Hamburger’s work with the State Department, he has initiated a number of projects engaging religious groups in disaster risk reduction. One of the most exciting of these is a project, developed in collaboration with the US Embassy in Islamabad, Pakistan, involves collaboration between U.S. and Pakistani scientists and engineers to develop a training program for religious leaders and madrassa (religious school) instructors in earthquake-threatened areas of Pakistan.

As a separate initiative that will occupied his last month in the Fellowship program, Hamburger served as an Embassy Science Fellow in Kathmandu, Nepal, where he will be working with the USAID office of Disaster Risk Reduction, Resilience, and Reconstruction (or “DR4” as they call it) on a multi-hazard risk assessment for the areas affected by the devastating 2015 Nepal earthquake. The project is intended to help train Nepali geologists and engineers in the challenging hazard assessments involved in return or relocation of the 20,000+ Nepali citizens displaced by last year’s devastating earthquake.

Hamburger hopes to bring some of the project work back to IU for student-based research projects. One initial product of Hamburger’s Washington work: IU is now a charter institution in the State Department’s Diplomacy Lab program, which will bring IU faculty and students as participants in State Department research projects, starting in fall of 2016.

In Memory: Robert Blakely

A long-time friend and colleague, Robert (Bob) Blakely, passed away late last week at his home in Baton Rouge at the age of 95. Bob was a highly talented geophysicist who worked both with the Department of Geology and the Indiana Geological Survey from 1949 through his retirement in 1986. His broad research and teaching interests ranged from applied geophysics to earthquake hazards to potential fields and meteorology. He worked closely with geophysics faculty Al Rudman and Judson Mead on problems of mid-continent basement geophysics and was a mentor to me and Gary Pavlis early on in our careers at IU. He is survived by "the love of his life" Rosanna Blakely, his wife of 73 years and daughter Linda Blakely Junker, both in Baton Rouge.

Bob was a delightful colleague and friend, and he will be greatly missed. Additional details on memorial arrangements and contact information to follow.

Don Hattin
In Memory: Professor Emeritus Donald Hattin

Professor Emeritus Donald Hattin passed away peacefully on Friday, June 24, 2016 in Bloomington Indiana.

Dr. Hattin joined the Department of Geological Sciences at Indiana University as an Assistant Professor in 1954 and remained with us until his retirement in 1995.

He received a B.S. in Geology from the University of Massachusetts-Amhers in 1950, an M.S. in Geology from the University of Kansas in 1952, and a Ph.D. in Geology from KU in 1954. Click here for more information.

A celebration of Dr. Hattin’s life and work will be held on Saturday, July 23rd at 11:30 am in the Tudor Room at the IU Memorial Union, with a reception to follow in the University club rooms.

SGE school demo
SGE Hosts Students from St. Charles Elementary

A group of 46 first grade students from St. Charles Elementary School visited the Department of Geological Sciences on May 12. Carley Gasaway, Kevin Webster, and Alex Zimmerman led hands-on geology activities with the students, covering rock and mineral properties, plate tectonics and Pangaea, along with fossils and ancient life. The students were able to test mineral properties with a variety of mineral samples, reconstruct the continents to form Pangaea, and examine Cretaceous marine fossils and replica dinosaur skulls to think about ancient animal diets.

Chaos limits predictability of hurricane intensities. If a butterfly sets off a hurricane halfway around the world, how well can we forecast the storm’s strength?

Quoting from Richard J. Fitzgerald in Physics Today: "Weather is the archetypical example of a chaotic system. Indeed, it was his calculations of weather models that led Edward Lorenz to his landmark 1963 paper that helped launch modern chaos theory. Lorenz famously gave a 1972 talk titled "Predictability: Does the flap of a butterfly’s wings in Brazil set off a tornado in Texas?" Chanh Kieu and Zachary Moon at Indiana University Bloomington now report on a related question: How well can we forecast the intensity of a hurricane? ...Using a minimal dynamic model, Kieu and Moon found that the limiting speed is stable: Simulated hurricanes approach that equilibrium value regardless of their initial conditions. Yet the errors in forecasts of hurricane intensity don’t go away as one might expect; rather, speed errors level off at about 8 m/s (18 mph) after four to five days in real-time intensity forecasts. Through full-physics simulations, the pair discovered that those errors arise from a so-called chaotic attractor at the maximum potential intensity limit. That finding implies that improvements in intensity forecasts are more likely to come from better modeling of the large-scale environment than from better knowledge of the storm's initial state. Even so, the researchers note, the maximum range of predictability is only about three days, and likely shorter for mature hurricanes."

Indiana University and Virginia Tech geochemists show experimental verification of key principle
Chen Zhu

Quoting IU Newsroom: Geochemists at Indiana University and Virginia Tech have developed and demonstrated a technique for assessing the validity of a principle that has long been important in thermodynamics and chemical kinetics but has proven resistant to experimental verification. Called the principle of detailed balance, the concept is widely used in models to ensure the long-term safety of environmental projects such as storage sites for nuclear waste and for carbon dioxide.

The study, A stable isotope doping method to test the range of applicability of detailed balance was published in Geochemical Perspectives Letters, a publication of the European Association of Geochemists. Co-authors are IU postdoctoral researcher Zhaoyun Liu and doctoral student Yilun Zhang; J. Donald Rimstidt of Virginia Tech; and Honglin Yuan of Northwest University in Xian, China.

"Even though this principle is the cornerstone of a great deal of chemistry and quantum mechanics, it is difficult to demonstrate," said Chen Zhu, professor of Geological Sciences in the College of Arts and Sciences and an author of the study. "We have assumed that it works in many situations without experimental verification." This work was funded by the National Science Foundation. Link to the IU Bloomington Newsroom article.

The evolutionary convergence of mid-Mesozoic lacewings and Cenozoic butterflies

Abstract: Mid-Mesozoic kalligrammatid lacewings (Neuroptera) entered the fossil record 165 million years ago (Ma) and disappeared 45 Ma later. Extant papilionoid butterflies (Lepidoptera) probably originated 80–70 Ma, long after kalligrammatids became extinct. Although poor preservation of kalligrammatid fossils previously prevented their detailed morphological and ecological characterization, we examine new, well-preserved, kalligrammatid fossils from Middle Jurassic and Early Cretaceous sites in northeastern China to unravel a surprising array of similar morphological and ecological features in these two, unrelated clades. We used polarized light and epifluorescence photography, SEM imaging, energy dispersive spectrometry and time-of-flight secondary ion mass spectrometry to examine kalligrammatid fossils and their environment. We mapped the evolution of specific traits onto a kalligrammatid phylogeny and discovered that these extinct lacewings convergently evolved wing eyespots that possibly contained melanin, and wing scales, elongate tubular proboscides, similar feeding styles, and seed–plant associations, similar to butterflies. Long-proboscid kalligrammatid lacewings lived in ecosystems with gymnosperm–insect relationships and likely accessed bennettitalean pollination drops and pollen. This system later was replaced by mid-Cretaceous angiosperms and their insect pollinators.

Chanh Kieu
Geosci faculty member Chanh Kieu’s research is featured in the Quarterly Journal of the Royal Meteorological Society

A recent research study by Chanh Kieu is now featured on the Quarterly Journal of the Royal Meteorological Society (November issue, 2015). In this study, he was able to demonstrate for the first time the stable equilibrium of the hurricane maximum potential intensity (MPI) under the wind-induced surface heat exchange hypothesis. The MPI solution was first found in 1986 by Emanuel, but its stability has been a long conjecture since then. Chanh’s recent work on QJ tackles this stability issue directly, thus answering a standing question related to the MPI equilibrium. More details can be found in this link:

Recent publication names a new species after Professor Emeritus Don Hattin

A publication titled, "Origin and phylogeny of the Cretaceous thoracican cirripede family Stramentidae" by A.S. Gale, which appeared in the Journal of Systematic Paleontology, includes a new species named Leweslepas hattini sp. nov.

Abstract: A cladistic analysis of basal scalpellomorph cirripedes was undertaken in order to identify the phylogenetic position of the Stramentidae. This yielded a well-supported tree, in which the family is positioned crownwards of Archaeolepas, but basal to the families Scalpellidae and Zeugmatolepadidae. A new genus, Loriolepas, is described to accommodate some species previously referred to Archaeolepas. Basal scalpellomorphs display a remarkable change in shell mineralogy from calcium phosphate to calcium carbonate (Eolepas to Archaeolepas); the latter group is identified as a monophyletic clade, the Thoracicalcarea nov. A revised taxonomy of the predominantly Late Cretaceous cirripede family Stramentidae is presented. Stramentidae are subdivided into two subfamilies, Loriculinae subfam. nov., and Stramentinae, based on characters of tergum, carinolatus and peduncular plates. The former subfamily includes Loriculina Dames, 1885, Metaloriculinagen. nov. and, doubtfully, Blastolepas Drushchits and Zevina, 1969, and three new species are described, Loriculina ifrimae sp. nov., Metaloriculina stramentioides sp. nov and Metaloriculina norvicensis sp. nov. The Stramentinae include Leweslepas gen. nov., Stramentum Logan, 1897 and Parastramentum gen. nov. New species are Leweslepas hattini sp. nov, L. hauschkei sp. nov, L. wrightorum sp. nov, Parastramentum albertaensissp. nov, P. brydonei sp. nov, P. peakei sp. nov, Stramentum alekseevi sp. nov and S. praecursor sp. nov. Cladistic analysis of the Stramentidae, based on 25 characters, supports the monophyly of the family, but relationships between subfamilies and genera are poorly resolved. However, in north-west Europe there is an evolutionary morphocline, stratigraphically calibrated, from the early Cenomanian Leweslepas hauschkei gen. et sp. nov. through the middle Cenomanian Stramentum praecursor sp. nov. to the late Cenomanian–Turonian S. pulchellum. A split from this lineage is found in the Western Interior Basin of North America, and the early Turonian S. canadensis gave rise to the middle Turonian S. elegans, which lived epibenthically. Stramentum elegans gave rise to Parastramentum gen. nov. Here is a link to the paper (PDF)
