geomorphic stratigraphic investigations goals for coastal plain
Geomorphic/Stratigraphic Investigations: Goals for Coastal Plain
  • Produce geologic map that is based on geomorphic mapping, subsurface analysis (cores, borehole geophysics, continuous subsurface imaging) and age dates.
  • Apply new concepts in sequence stratigraphy, and ensure that the Code is appropriately applied to accommodate modern concepts in landscape evolution.
  • Produce paleogeographic reconstructions from geomorphology.
current funded projects
Current funded projects
  • Lizzie project: $25,000 from DWQ to characterize 3D geology at Lizzie Research site; complete by Sept. 30, 2001.
  • 319A project: pending 16 month, $96,000 grant from EPA through DWQ to characterize geology of Little Contentnea Creek Watershed of Neuse River Basin.

NCGS Role: Collaboration
  • To provide a conceptual model for the geomorphic and stratigraphic evolution of the Little Contentnea Creek Watershed (10 digit code) of the Neuse River Basin.
slide20
Why?
  • To understand and model the distribution of shallow aquifer-related facies in a complex assemblage of predominantly Pliocene and younger surficial deposits in a low relief area with few outcrops.
  • To provide a template for planning the pending subsurface field investigation (319A) to confirm, revise, or reject the proposed conceptual model.

Conceptual Model
  • Modern drainages follow paleovalleys that existed prior to the mid-late ? Pliocene Yorktown transgression.
  • Interfluves have been relatively fixed in position for this same period.
  • Paleovalleys and interfluves have distinctly different stratigraphic signatures.
iterative process
Iterative Process
  • Provide overview of Neuse R. Basin geomorphology from existing data sets.
  • Map geomorphology at site specific scale (100 km2 at the Lizzie Research Station.
  • Analyze the 3D sequence stratigraphic framework at site specific scale (100 km2).
  • Produce regional (scale = 102 km2), GIS-based, maps of geomorphic features using concepts from site specific studies.
  • Extrapolate stratigraphic concepts regionally and plan subsurface analysis for model confirmation (319A).

EducationProject Earth Science

Project Earth Science is the NCGS program designed to provide relevant and accurate earth science information for the state's high school students and Earth/Environmental science teachers.

Project Earth Science consists of curriculum and professional development programs that meet the Department of Public Instruction's competency-based curriculum objectives.

    • Handle inquiries about education (~30/month)
vision for the future
Vision for the future
  • Research our clients
    • Develop NCGS Education GIS project that allows us to track needs and developments over time and to identify those teachers needing but not yet receiving materials and assistance.
  • Expansion
    • Obtain funding for this position for travel, professional development and intern.

        • Fund "scholarship" program for the teachers where we issue coupons good for any of the items we sell.
slide47
Geology and Mapping
    • We need to help our earth science teachers understand better how to interpret a geologic map. I propose to develop a series of inquiry investigations aligned with new and published mapping and write grants to conduct workshops to train teachers about their use and value in teaching community geology.
  • Geohazards
    • Develop Rick's debris flow hazards poster into a Web resource for educators
  • GIS/data
    • Create coverages based on our three years of teacher surveys. This data will uncover how we can better serve the teachers based on what they tell us they want from our agency.
  • Resource Evaluation
