A session talk and a poster were presented by me at the 2015 GSA Annual Meeting in Baltimore, MD. In my talk, I discussed evidence of significant erosion across the entire family of Carolina bays. Such evidence help support an age of 800,000 years for the formative event. Entitled “They Don’t Build 'Em Like They Used To; Examining Lidar Of Modified Costal Terrace Surfaces Shows The Carolina Bay Landform To Be Robust When Threatened With Alteration By Gradualistic Processes”, and a PDF version of the talk is available from the GSA via the link HERE. The poster shared the the new LiDAR available from Virginia, and how that re-emphasizes the uniqueness of the Carolina bays present across the “upland Gravels” of Virginia on the surviving Midlothian/Bon Air terrace: “Lidar Elevation Data Provides New Insight Into The Bon Air Gravel And Attendant Carolina Bays”. The abstract and a link to the poster PDF is available form the GSA site linked HERE, and displayed in a smaller image below.
A session talk and a poster were presented by me at the 2013 GSA Annual Meeting in Denver, CO. The talk attempted to review the derivation of the six bay planforms currently being utilized to measure Carolina bays in the Survey. Entitled, “A Proposed Taxonomy For Carolina Bay Circumferential Rim Planforms; Findings Of Robust Adherence To Distinctive Archetypes Is Supported By Lidar-Derived Digital Elevation Maps”, the link connects to the GSA abstract page, which hosts a link to an annotated PDF version of the slide deck. The poster, entitled Carolina Bays And Aeolian Dunes: Playing Nice In The Sandbox?, reviews the juxtaposition of aeolian dunes and Carolina bays in several settings. LiDAR imagery was used extensively in both the Poster and the Talk to support the discussions.
A poster was presented at the 2012 GSA Annual Meeting in Charlotte, NC. There we explored the Cape Fear River Valley and the terraces within, in an attempt to revisit David Soller’s observations regarding Carolina Bay ages. Entitled, Where The Bays Are: A Temporal Tale Of Carolina Bay Geomorphology As Told In Lidar By The Wando And Socastee Terraces, the link connects to the GSA abstract page, which links to an on-line version of the poster.
The 2012 GSA Southeastern Section Meeting allowed me the opportunity to present an oral talk on the subject SURFICIAL QUARTZ SAND DEPOSITS ON THE ATLANTIC COASTAL PLAIN: EOLIAN, FLUVIAL OR MARINE? THE CASE FOR A CATASTROPHIC DELIVERY MECHANISM. Link is to the GSA abstract page, which contains a link to the lecture slides and notes.
I presented an oral talk at the 2012 GSA Northeastern Section Meeting in Hartford, entitled LIDAR-DERIVED DIGITAL ELEVATION MAPS OF MARYLAND, DELAWARE AND NEW JERSEY USED TO IDENTIFY CAROLINA BAY LANDFORMS. Link is to the GSA abstract page, which contains a link to the lecture slides and notes.
We presented a poster at the 2011 GSA Annual Meeting in Minneapolis. The poster content, seen below, is also available as a PDF for download. I presented a TALK on the Survey and its use of LiDAR & Google Earth. A PDF of the deck is available HERE.
We presented a poster at the 2011 Southeastern Section GSA Meeting in Wilmington. The poster content, seen below, is also available as a PDF for download.
We presented a poster at the 2010 GSA Meeting in Denver. The poster content, seen below, is also available in a booklet PDF file.
We also had the opportunity to give an oral presentation on our use of LiDAR in this research at the 2010 GSA Meeting in Denver. A PDF of the presentation is available for download from HERE, or can be viewed as web pages HERE.
We presented a poster (PP31D-1387 Geomorphology Of Possible Younger Dryas Boundary Impact Structure) at the December 2009 AGU Fall Meeting in San Francisco which detailed some of our concepts as they pertain to the Carolina bays and their role in identifying a possible ice shield impact crater. A PDF file of the submission in slide presentation form is available for download HERE. Links are available to two videos on You Tube (Part 1& Part 2) in which we discuss the poster at the AGU meeting. Please note that since the meeting, we have refined the impact location to the Saginaw Bay area of Michigan. The small version below is linked to a higher resolution pdf.
Two videos filmed by George Howard are available on YouTube. In these videos, our AGU poster is referenced to discuss the distal ejecta conjecture and the Carolina bay inferred alignments. Click on the images below to watch the video. Note that since the AGU Fall Meeting we are now proposing an impact in the Saginaw area vs the Lake Michigan basin, as discussed in the 2nd video.
