It is anticipated that this latter version will be adequate for most # users, while the former provides a full documentation for those who wish to carry out more # detailed analyses. # # Column numbers: see Hijma et al. (2014) for a detailed description. # # Limiting data: # Note that the elevation is calculated in the same manner as for Paleo-RSL. # However, it is recommended that limiting data are plotted with a horizontal # bar with a width defined by the 2sigma age range, and an elevation that takes # into account the upward error (for upper limiting data) or downward error # (for lower limiting data). # # Source References: # Blum MD et al.

A rigorous, objective error assessment assures that all conceivable sources of uncertainty are accounted for, thereby allowing direct comparison of data from different regions and environments. New developments in the methodology presented here include a more extensive treatment of age errors, plus modeling of modern as well as paleotidal parameters. The methodology is illustrated with an example from the US Gulf Coast. #------------------ # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: EAR-0717364, EAR-0717496, EAR-0719179 #------------------ # Site_Information # Site_Name: Central US Gulf Coast # Location: North America>United States Of America # Country: United States # Northernmost_Latitude: 31.0 # Southernmost_Latitude: 28.0 # Easternmost_Longitude: -89.0 # Westernmost_Longitude: -98.0 # Elevation: 0 m #------------------ # Data_Collection # Collection_Name: Gulf Coast RSL Database Complete 77 Variables # Earliest_Year: 9660 # Most_Recent_Year: 150 # Time_Unit: Cal.
