May 18, 2022: Wow, wow! Coastal Geo Lab masters (and soon to be PhD) student Mary Bryan Barksdale was today awarded a two-year Margaret A. Davidson Fellowship from the NOAA National Estuarine Research Reserve program. Congratulations MB!
February 16, 2022: Paper alert! Mahina Robbins' senior thesis was published today as a peer-reviewed manuscript in Geomorphology. This paper quantifies area/volumetric changes in the Virginia Barrier Islands over the last ~180 years, and explores some of the responsible mechanisms. Check it out here, or drop us an email for a copy.
January 26, 2022: With the start of the new semester, we wanted to wish a warm (and in some cases long overdue) welcome to the lab to FOUR new undergraduate students: Ally Gravgaard Nathaniel Ingle, Ethan Stewart, & Grace Weeks. Check out our People page for more info on this great new team of young coastal geoscientists.
November 15, 2021: The VIMS Coastal Geology Lab had a MAJOR milestone today, as we celebrated the successful PhD dissertation defense of Justin Shawler. Congratulations Dr. Shawler! Justin is next heading off to a career with the Coastal and Hydraulics Laboratory of the U.S. Army Engineer Research and Development Center.
August 30, 2021: With the start of the new semester, we're excited to announce two new developments in the Coastal Geology Lab.
Secondly, Chris is excited to announce he has taken the reins as co-director of the VIMS/W&M Undergraduate Program in Marine Science. This incorporates our undergraduate Marine Science Minor, as well as undergrad contributions to research, outreach, and advisory service at VIMS.
July 20, 2021: Justin Shawler's second PhD chapter has been published (open access) in Quaternary Science Reviews! This manuscript, based on a ton of sediment cores, ground-penetrating radar, and geochronology, tells the 2500-year story of the formation and growth of Chincoteague, Assateague, and Wallops islands in northeast Virginia. Justin then goes on to calculated associated sand volumes sequested within these systems through time, and compare them to those contained within the islands to the south, and other progradational coastal systems globally. Congrats especially to Justin and W&M graduate co-authors Chloe Obara and Mahina Robbins. Check it out here: https://doi.org/10.1016/j.quascirev.2021.107096
April 27, 2021: Congratulations to Sarah Grace Lott, who earlier today defended her undergraduate thesis in the W&M Geology Department, earning 'high honors'! Her study, conducted in collaborationwith colleagues from the Federal University of Santa Catarina's Coastal Oceanography Lab was of headland bypassing processes and landforms in the Ubatuba-Capri strandplain-spit system of São Francisco do Sul, Santa Catarina, Brazil.
October 29, 2020: Busy week . . . . but, pleased to share our newest publication, led by Ana Paula da Silva (now at Griffith University in Australia) and colleagues at the Federal University of Santa Catarina. Out today in Scientific Reports this paper presents a record of changing Southern Atlantic wave climate during the last 5000 years as recorded in beach ridges at Pinheira, Brazil (one of my first study sites!). Check it out here: https://doi.org/10.1038/s41598-020-75265-5
October 27, 2020: Whelp, it's been more than six years since Justin Shawler joind the Coastal Geology Lab as an eager W&M undergrad majoring in Government, before going on to complete an honors thesis and is nearing completion of his PhD with our group. Today we are pleased to announce that he is putting that policy interest to work, as he has accepted a position as Coastal Scientist with the Delaware Department of Natural Resources and Environmental Control (Division of Watershed Stewardship, Shoreline and Waterway Management Section). Justin will be starting there in January and working to complete his PhD remotely over the months that follow.
October 26, 2020: Very proud to share today's news that Justin Shawler's first PhD chapter has been published in Sedimentology! This very cool (IMHO) study combines detailed chronostratigraphic field data from barrier islands throughout the US Mid-Atlantic coast with morphodynamic modeling to explore the role of antecedent substrate in modifying barrier-island migration behavior. What is truly novel here is the integration of the field and modeling data in a way rarely accomplished in single studies. Congrats to Justin, Coastal Geology Lab technician Jennifer Connell, W&M graduate Bianca Boggs, and collaborators Dan Ciarletta & Jorge Lorenzo-Trueba. Check it out here: https://doi.org/10.1111/sed.12798
June 30, 2020: The team is just back from a nearly two-week, mask-wearing, socially distant field campaign to Virginia's Eastern Shore. Focused on Kayla Cahoon's MSc thesis work mapping Pleistocene geology and intrglacial sea-level highstands, this campaign resulted in collection of 12 Geoprobe cores for a total of 716 feet of sediment. Now, the real work begins . . . Shown in the photo below are (L-R): Cameron Clark (W&M ugrad), Sarah Grace Lott (W&M ugrad), Bruce (drill rig), Justin Shawler (VIMS PhD student), Jenn Connell (lab genie), Kayla Cahoon (VIMS MSc student), & Mark Lundine (UDel PhD student).
May 20, 2020: Paper alert! Well, a book chapter in this case, authored by Chris Hein and collaborator Andrew Ashton. Published in the new Sandy Beach Morphodyanmics book edited by Derek Jackson & Andy Short, our chapter reviews the controls on long-term shoreline evolution and how associated progradational systems can record multi-decadal through multi-centennial coastal change.
May 6, 2020: We are pleased to share a new paper linking hydroclimate (Indian summer monsoon) & global carbon cycling via soils & rivers. Out today in Nature, this NSF-funded study finds a negative relationship between monsoon rainfall & soil C age on millennial timescales. What’s this mean? That warmer & wetter climate after the last glacial enhanced soil respiration & decreased soil C stocks. With climate change likely to increase rainfall in the tropics, this means accelerated soil C destabilization & addition of even more CO2 to the atmosphere. For more, see the VIMS story about this paper.
April 6, 2020: We're pleased to welcome Elizabeth Davis as a new PhD student in our group in the fall! Liz is currently completing her masters at the University of Delaware studying the Savage Neck Dunes of the Virginia Eastern Shore. At VIMS she'll be working on our new project with collaborators Nick Cohn of the U.S. Army Engineer Research and Development Center and Julie Zinnert of Virginia Commonwealth University studying artifical and natural sand dunes along the North Carolina Outer Banks. Welcome Liz!
December 27, 2019: Chris had the opportunity tonight to present the results of our many years of work studying erosion on Plum Island to those most impacted by that erosion. He gave an hour-long (plus 45 min of Q&A!) talk to an overflow crowd of >200 residents of Newbury and Newburyport at the Newburyport Senior Community Center, detailing our new understanding of coastal processes at this river-mouth barrier island, detailed in papers in Frontiers in Earth Science, Anthropocene Coasts, Coastal Management, and the Journal of Coastal Research. His talk was previewed in the Newburyport News and the Town Common.
November 11, 2019: We're pleased & proud to announce two pieces of great news for PhD student Justin Shawler. First, he was recently awarded a highly competitive Maury Fellowship from the VIMS School of Marine Science. And second, after years of effort, the work developed from his W&M Geology honors thesis was published in the open-access Anthropocene Coasts. Check it out here: Tidal erosion and upstream sediment trapping modulate records of land-use change in a formerly glaciated New England estuary.
September 17, 2019: We are recruiting a PhD student to work on a new three-year grant funded by the NOAA Ecological Effects of Sea-Level Rise program. Titled “Is an old dune a more resilient dune? Assessing the importance of ecological history in coastal protection from storms and sea-level rise”, this project will couple stratigraphy, remote sensing observations, morphologic modeling, & ecology to study the resilience of natural & artificial sand dunes along North Carolina’s Outer Banks. This collaborative, inter-disciplinary project will include extensive field work at the USACE Field Research Facility and across the broader Outer Banks, including participation in the During Nearshore Event EXperiment (DUNEX, https://uscoastalresearch.org/dunex) in Fall 2020. Read the project abstract.
The student will join the VIMS Coastal Geology Lab and School of Marine Science starting in summer 2020. Top applicants will have strong quantitative backgrounds and an interest in coastal sedimentology. We particularly encourage applications from students from diverse backgrounds and demonstrating a commitment to the Institute's mission of diversity and inclusion.
June 3, 2019: PAPERS! Two manuscripts have recently come out from the group. The first, published in Frontiers of Earth Science, is developed in part from the masters thesis of Andy Fallon and senior theses of Sarah Baker and Brody Marino. It was funded by our NSF Coastal SEES project and explores the mechanisms driving cyclical erosion and human responses along Plum Island, MA. The second, led by collaborator Dan Ciarletta of Montclair State University, was published in Journal of Geophysical Research: Earth Surface, and presents a new morphodynamic model of beach and foredune ridge formation, which allows us to quantify paleo sediment fluxes from preserved ridge morphology.
May 30, 2019: Justin & Chris attended the Coastal Sediments 2019 meeting in Tampa Florida. Forgot to take pictures, but, better than that, each presented papers covering studies of Cedar Island evolution and of sediment trapping in beach ridges in Brazil and Virginia.
May 15, 2019: We are very pleased to announce that Kayla Cahoon (W&M 2019) has accepted our offer to join the VIMS Coastal Geology Lab! Check the People page soon for more info on Kayla and her masters thesis.
May 12, 2019: Graduation Day. Always bittersweet, as this time we send off into the world two young women of whom I am immensely proud: Bianca Boggs & Kendall King. Working with these students remains one of my greatest pleasures of this job. You can check below and see that I (Chris) am wearing the same outfit as last year. Except for the crown.

Proud advisor Chris also gave a talk, served as conference Technical Co-Chair, and took a handful of grainy photos. Read more about the Geo Deparment's participation here.
August 10, 2018: Busy week around here . . . today our paper, led by Kate French (formerly WHOI postdoc, now US Geological Survey) and Valier Galy of WHOI, was published (open access) in Nature Scientific Reports. I tweeted about it here. The short version: organic matter exported from rivers is old. 80% of plant waxes from the Ganges & Brahmaputra rivers are 1000s of yrs old, stored in soils & floodplains. The rest cycle in decades, and track paleoenvironmental change.
August 7, 2018: Second student defense in one week! Last week it was Soely, today it was Julie Krask!

December 8, 2016: Charlie Deaton's 2015 William & Mary senior research was published online today in the journal Geology. A fantastic achievement by this young scientist! This work traces barrier island and marsh change on the Eastern Shore of Virginia over the last 150 years and tests the so-called "runaway transgression" hypothesis, finding that any couplings between barrier island dynamics and associated backbarrier marshes are entirely overwhelmed by independent barrier-island migration, likely driven by changes in longshore sediment supply. Check it out here: Barrier island migration dominates ecogeomorphic feedbacks and drives salt marsh loss along the Virginia Atlantic Coast, USA.
