Seafloor Data

• Based on point data to maximize spatial
  resolution
• Algorithmic underlying data system allows
  progressive improvement and extension addition
  of new data also highly efficient
• US, Australian and global coverages (300k, 400k,
  800k attributed points, growing at 20k points /
  month)
• Statistical validation of outputs using paired
  measurements in underlying database measurement
  and spatial uncertainties available with data

• Now available interactively on the web
• Validated numeric seafloor data for input into
  physical models of MBP and sediment transport
• Try it at instaar.colorado.edu/deltaforce/
  usseabed/interactive/ or Google for dbSEABED or
  iSEABED

Q. What physical property inputs should I put
into a numerical MBP model for this site ?

Many types of studies and analyses are now
possible on the unified point data

• Geostatistics of seabed heterogeneity now
  available across many environments and locations
  in this case plotted using semivariograms
• Sediment facies are resolved, including here
  paleochannels holding muds
