GA426 (Site Name Keyword)
1-2 (2 Records)
Five sediment samples from two cores collected at site GA426, located approximately 31 miles offshore near Galveston, Texas, were examined for pollen. The site is on an old river terrace that is now submerged in an estuary or back bay. The site is a possible Paleoindian site that is expected to date to between approximately 9,000 and 10,000 BP. The area was above water during the last glacial maximum and was subsequently submerged in the range of 8,400 to 10,000 BP (Patrick Hesp, personal...
POLLEN AND ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM SITES GA426 AND HI178, TEXAS GULF COAST (2010)
Three core samples recovered from two underwater sites (GA426 and HI178) on the outer continental shelf off the Texas coast in the Gulf of Mexico were submitted for pollen and organic residue analysis. Two of the samples were examined for organic residues using Fourier Transform Infrared Spectroscopy (FTIR), and two were examined for pollen. Pollen and organic residue analysis will be used to determine if the core samples represent sites on land or deposition of floral remains blown to sea.
