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.

17
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.

18
NCGS collaboration with DWQ- Ground Water Section
and USGS-WRD Neuse River Basin modeling

Unmapped Pliocene-Quaternary terrain
19
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.

20
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.

27
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).

• Vision for the Future

40
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.

41
Where have we been?

• Collaborative Projects
• DENR, Mining Commission, Industry
• Talking Rocks Trail
• Mining Commission, DENR, NC DPI, UNC system
• North Carolina Rock Kit Project (850,000 reached)
• NC DPI
• Earth/Environmental Science Curriculum for grades
  9-12, N. C. Standard Course of Study.
• Earth/Environmental Science Reference Tables and
  Support Documents for grades 9-12, N. C. Standard
  Course of Study

42

• Outreach
• School Programs, Public Programs, Workshops and
  Field Trips (113,358 teachers, students and
  citizens reached)
• Service

  Science Teachers advisory board.
• Member of the EarthView advisory board.
• Designate for Department of Environment Natural
  Resources Strategic Planning Environmental
  Awareness/Outreach Team
• Board member of Education and Industry Committee
  for Earth Science in N. C.

43
Current Focus

• Shift to education curriculum development
• Since Spring 2000 semester, NSF Graduate Research
  Trainee fellow in earth science education and
  instructional technology
• Inquiry Teaching and Learning of
  Earth/Environmental Science Concepts using
  Mapping and New Technologies
• A new inquiry-based curriculum about maps, for
  grades 9-12. The curriculum will support the
  Earth/Environmental Science course and feature
  the state's physiography and geology. A digital
  version will be developed to be served on-line.

44

• Rock Kits for grades 9-12
• Redesign our popular Rock Kit project for grades
  9-12. This version is a full kit of mineral and
  rock specimens plus a inquiry based curriculum
  activities, data sheets and background materials
  keyed to the standard course of study.
• Service
• Maintain the listserv that serves the state's
  earth science teachers by informing them of
  workshops, current events, currents ideas and
  practices in education.
• Coordinate the National Association of Geology
  Teachers Outstanding Earth Science Teachers'
  Award.
• Compiled Resources That Support The Earth/
  Environmental Science Requirement For North
  Carolina Schools
• Handle inquiries about education (30/month)

45
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.

46

• Write grants to obtain funding to provide our
  current and future clients with the resources and
  training they need to successfully implement the
  Earth /Environmental science curriculum.
• Collaboration
• Integrate education function with other key
  functions of NCGS.
• Map/Pub Sales
• Added items to our stock especially for the
  teachers This Dynamic Planet poster, Dynamic
  Planet booklet, Time and Terrain map, Geology of
  the Solar System map. Looking at AGI curricula.  
• Fund "scholarship" program for the teachers where
  we issue coupons good for any of the items we
  sell.

47

• 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
• Assist Jeff with Mineral Atlas Web resource for
  teachers.
