My official retirement began in January 2013 but was prefaced with a one-year sabbatical after completing my last teaching class in December 2011.  Leading up to retirement, I spent a great deal of time planning for the distribution of research samples that we had collected during the previous 40 years.  This effort also included a collaboration with several colleagues to establish an archive for Amino Acid Racemization (AAR) data at the NOAA Paleoclimatology site (see links below).  Beginning in January 2013, I devoted large amounts of time to the organization of our research collection and the physical transportation or shipment of samples to several institutions around the country (Los Angeles County Museum of Natural History; Paleontological Research Institution, Ithaca, NY;  Florida Museum of Natural History, Gainesville, FL; The Academy of Natural Sciences of Drexel University, Philadelphia; and the Delaware and North Carolina Geological Surveys), an effort that required about three years to complete.   Several efforts to synthesize data and to explain our data management procedures also occurred during this time (Wehmiller et al., 2015; Wehmiller and Pellerito, 2015a, 2015b).  


A fortuitous an unexpected combination of events starting in 2014 led to a major project that has resulting in a very satisfying publication (Wehmiller et al., 2021). I credit my colleague Kelvin Ramsey of the Delaware Geological Survey with the insight to realize that AAR data would be useful in understanding the links between the offshore and onshore Quaternary stratigraphy of the mid-Atlantic coastal region, thereby inviting me to participate in this multi-year project. Only in retrospect do I realize that my participation in this project would have been difficult had I had all the “normal” responsibilities associated with a full-time faculty position. Ramsey was responsible for managing an offshore sand resource project funded by the Bureau of Ocean Energy Management (BOEM), motivated by the need to assess these resources post- Hurricane Sandy.   The on-going offshore geophysical work of Laura Brothers (USGS, Woods Hole) and her colleagues was a major component of this project, allowing us to understand the geochronologic relation of offshore and onshore units, and even gain insights into the late Quaternary history of local barrier islands.  The mid-Atlantic results also have a counterpart in a related BOEM project for the SE US (Wehmiller et al., 2019.)  These offshore studies will hopefully contribute insights not only related to sand resources but also for the understanding of late Quaternary sea-level history and offshore wind farm development, and the overall effort certainly indicates the utility of AAR in offshore stratigraphic research.


As part of the BOEM project, we also developed an on-line database (ArcGIS Online) of AAR data in order to facilitate discussion within the working group of colleagues involved in the BOEM project.  This database is a living document that will evolve as new data and interpretations are added.
