Research Associate Professor Rachel Abercrombie has received 3 new research awards in the last few months to continue her work in earthquake seismology. She is collaborating with scientists and graduate students at a number of different universities and institutions. The awards, their focus, and Prof. Abercrombie’s work on them are described below:
NSF Collaborative Award
The U.S.-led international experiment project titled Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip or HOBITSS deployed an ocean bottom instrument array offshore New Zealand. The aim is to investigate the physical environment that hosts shallow slow slip and its relationship to destructive, seismic slip on the Hikurangi subduction thrust. Prof. Abercrombie is a PI with Prof. Schwartz (UCSC) and Prof. Sheehan (U Colorado) on a two-year project that will build on the initial data analysis from this experiment. Prof. Abercrombie is leading the analysis of earthquake source parameters to explore their spatial and temporal relationships with slow slip, geodetic coupling and physical properties of the plate interface.
The original deployment and early results featured in a recent EOS article titled “Investigations of Shallow Slow Slip Offshore of New Zealand.”
NSF Collaborative Award
Prof. Abercrombie and Prof. Chen (University of Oklahoma) received three years of funding to investigate earthquake stress drops, their uncertainties, and spatial and temporal changes using data from around Parkfield, California. This section of the San Andreas Fault near Parkfield, has a high rate of earthquakes, and is one of the best-instrumented sections of fault in the world.
Southern California Earthquake Center Award
For this one year award, Prof. Abercrombie is working with Prof. Shearer at UCSD to improve measurements of earthquake stress drop in Southern California.
Prof. Abercrombie also regularly visits scientists at MIT and Harvard with whom she works on a range of different projects. To learn more about her work, check out her profile page.
Duncan FitzGerald gives invited talks in Brazil and Netherlands; attends thesis defense in Netherlands
Earth & Environment Professor Duncan FitzGerald was recently in Santa Catarina, Brazil to give an invited talk titled “Future of northern latitude marshes and their effects on barrier island sand reservoirs” at the Universidade Federal of Santa Catarina.
Professor FitzGerald was also in the Netherlands recently where he gave an invited colloquium titled “Diverse styles of coastal evolution along Santa Catarina Brazil” at the University of Utrecht.
While at the University of Utrecht, Prof. FitzGerald also attended a thesis defense as an outside committee member for University of Utrecht Phd Candidate Wim Ridderinkhof. Ridderinkhof’s thesis was titled “Morphodynamics of ebb-tidal deltas.”

Earth & Environment Associate Professor Michael Dietze will be at the Burren bar this coming Monday June 13th at 6:30 pm to give a brief talk on “Fires, Invasives and Ticks, Oh My! Forecasting Ecology in a Changing World” as part of the Science by the Pint series sponsored by Harvard Graduate School of Arts & Sciences.
The Burren is located in Davis Square in Somerville at 247 Elm St. All members of the public are welcome to attend the event and meet and hear Prof. Dietze’s talk.
Earth & Environment Assistant Professor Dan Li has published a new paper in the Journal of Fluid Mechanics.
The paper titled “Connections between the Ozmidov scale and mean velocity profile in stably stratified atmospheric surface layers” can be read at this link.
In addition, Prof. Li has also had two papers accepted in the Journal of Advances in Modeling Earth Systems.
The paper “Exploring historical and future urban climate in the Earth System Modeling framework: 1. Model development and evaluation” can be accessed here.
The paper “Exploring historical and future urban climate in the Earth System Modeling framework: 2. Impact of urban land use over the Continental United States” can be accessed here.
To learn more about Professor Li’s work, check out his profile page.
The article, “Empirical evidence of contrasting soil moisture-percipitation feedbacks across the United States,” is available online at this link.
Tuttle and Salvucci’s work also received news coverage. A brief article titled “Soil moisture alters next-day rainfall in the United States” that discusses their findings can be found here.
Salvucci was Tuttle’s PhD advisor. To learn more about his work, check out his profile page.
Three Earth & Environment PhD candidates are among the winners of this year’s NASA Earth and Space Science (NESSF) Fellowship Program:
Eric Bullock was awarded the NESSF for his project titled “Improved Activity Data for Carbon Emissions from Forest Degradation Through Multi- Sensor Time Series Analysis in Southeast Asia.” Bullock is advised by Earth & Environment Professor Curtis Woodcock.
Taejin Park was awarded his fellowship for his project titled “Investigation on Changing Photosynthetically Active Growing Season and Gross Productivity of Northern Boreal/Arctic Vegetation Using EOS MODIS and Suomi VIIRS Data in Conjunction with Ground Observations.” Park is advised by E&E Professor Ranga Myneni.
More information about the NESSF program can be found here.
Earth & Environment Professor Duncan FitzGerald and his former graduate student, and now Assistant Professor at William and Mary, Chris Hein have published two new papers in the Journal of Coastal Research (JCR) and Sedimentology.
The JCR paper titled “Records of migration and ebb-delta breaching at historic and ancient tidal inlets along a river-fed paraglacial barrier island” is available online at this link.
The Sedimentology paper titled “Complex coastal change in response to autogenic basin infilling: an example from sub-tropical Holocene strandplain” is available online at this link.

The paper “Predicting the evolutionary dynamics of seasonal adaptation to novel climates in Arabidopsis thaliana” is available online now at this link.
Wang is a PhD student in Geography advised by Professor Mark Friedl.

Earth & Environment Research Associate Professor Rachel Abercrombie and recent E&E PhD recipient Dr. Kasey Aderhold (now with IRIS) have published a new paper in Journal of Geophysical Research – Solid Earth.
The paper is titled “Seismotectonics of diffuse plate boundary: Observations off the Sumatra-Andaman trench,” and it can be downloaded here.
The work in the paper formed a chapter in Aderhold’s PhD thesis. Aderhold received her PhD in Earth Science from Boston University this past year. Abercrombie was her advisor.
