Title: Northern California cross-shore transects for CoSMoS 3.2
Abstract:
Cross-shore transects (CSTs) developed for Coastal Storm Model (CoSMoS) work in Northern California 3.2 are presented. 3,528 CSTs are numbered consecutively from 8067 at Golden Gate Bridge to 11,594 at the California/Oregon state border. Each of the profiles extend from the approximate -15 m isobath to at least 10 m above NAVD88 (truncated in cases where a lagoon or other waterway exists on the landward end of the profile), and are spaced approximately 100-250 m apart.

Why was the data set created?

The Coastal Storm Modeling system uses several tiers of numerical models to make detailed predictions (meter-scale) of flooding and erosion over large geographic scales. This requires a common structure for comparison of data and for boundary conditions for higher-resolution models. Cross-shore transects (CSTs) allow this common structure and are presented for CoSMoS Northern California 3.2. These data are intended for science researchers and technical users.

How was the data set created?

  1. From what previous works were the data drawn?
    CDIP (source 1 of 1)
    Coastal Data Information Program (CDIP), 2019, MOP v1.1 model output: Scripps Institute of Oceanography, University of California, San Diego, California, online.

    Online Links:

    Type_of_Source_Media: online database
    Source_Contribution:
    defined alongshore model-output site locations modified for use in Northern California
  2. How were the data generated, processed, and modified?
    Date: 19-Jul-2019 (process 1 of 2)
    Alongshore transect locations from Coastal Data Information Program (CDIP) were modified (onshore position adjusted) to better capture cross-shore profiles for shorelines of interest and avoid large offshore rocks (when able). Keeping offshore positions the same or close to originating MOnitoring and Prediction (MOP) lines was a priority, to preserve the ability to compare data from other efforts using CDIP's MOPv1.1 transect lines. Data sources used in this process:
    • CDIP
    Data sources produced in this process:
    • CST lines
    Date: 10-Aug-2022 (process 2 of 2)
    Start and end points for transects/lines were saved as CSV. Data sources used in this process:
    • CST lines
  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    Attribute values are locations of user-defined transect end-points and are valid as described.
  2. How accurate are the geographic locations?
    A formal accuracy assessment of the horizontal positional information in the data set has not been conducted
  3. How accurate are the heights or depths?
    Not applicable.
  4. Where are the gaps in the data? What is missing?
    Dataset is considered complete for the information presented.
  5. How consistent are the relationships among the observations, including topology?
    Location data have undergone QA/QC and display as expected.

How can someone get a copy of the data set?
