Gulf of Mexico: Data Report. Report NRL/MR-MM/7430--01-8548, U.S. Naval Research Laboratory, Washington, DC, 12 pages.
Sediment cores and grab samples were collected in the N.E. Gulf of Mexico for the purpose of categorizing the seafloor environment. This report presents results of shore-based analyses performed on the cores and grab samples. Interpretive results are not included. The unopened cores were continuously logged with a multisensor core logger, X-rayed for internal structure identification, and subsequently split open where the core material was tested for mass physical and mechanical properties. This is an NRL CD data report containing spreadsheets that include: the logged data (compressional wave velocity, bulk density by gamma-ray attenuation, derived porosity and scoustic impedance), the laboratory determined properties (natural water content, undrained shear strength, and particle size distribution parameters), core and grab sample photos, and maps of the surficial sediment properties.
Data are also available from the U.S. Naval Research Laboratory (http://22.214.171.124/) as NRL Multi-Media Report NRL/MR-MM/7430--01-8548.
