  13. Dr. Kathleen M. Farrell, P.G. Senior Geologist for Stratigraphy and Geomorphology Current Geomorphic and Stratigraphic Investigations LIZZIE Site Little Contentnea Watershed Coastal Plain Coalition STATEMAP Compilation

  14. 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.

  15. 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.

  16. NCGS collaboration with DWQ- Ground Water Section and USGS-WRD: Neuse River Basin modeling efforts Unmapped Pliocene-Quaternary terrain

  17. 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.

  18. 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.

  22. Site – Specific Study Lizzie Research Station Upscaling Little Contentnea Creek Watershed

  23. Surficial units 20 m 16m 12 m Nestedvalley fills Wicomico Plain = interfluve 1 km

  24. 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.

  25. 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).

  27. Other Projects • State Map 9 and 10: work with J. Nickerson, K. Gay to compile Raleigh 100K Coastal Plain quads. (Hoffman) • NPS: collaborate with B. Hoffman to construct geomorphic maps of National Parks on coast. (Hoffman) • Finalize coastal atlas project – “Geologic Environments of the Lower Cape Fear River”

  28. Proposed Projects • Continue mapping Coastal Plain sector of Neuse River Basin: 319 B Project - $300,000 3-year project. Probable funding source = EPA. Deadline for submittal is Spring, 2002. • Continue geomorphic and geologic mapping of Cape Fear River Basin beginning with heavily populated New Hanover and Brunswick Counties, includes sinkholes studies. Funding sources sought (possibly FEMA).

  36. Mary Watson Project Geologist – Education and Outreach Coordinator • Project Earth Science • Where have we been? • Current Focus • Vision for the Future

  37. 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.

  38. 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 ScienceCurriculum 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

  39. Outreach • School Programs, Public Programs, Workshops and Field Trips (113,358 teachers, students and citizens reached) • Service • Member of the N. C. Leadership Network for Earth 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.

  40. 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.

  41. 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)

  42. 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.

  43. 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.

  44. 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.
