PLEASE NOTE: TIME CHANGE FOR SC2 - COURSE BEGINS AT 8:30 a.m. and ends at 5:00 on Sunday, March 16


SC-1: Google Earth Applications in Education and Research  
Date:  Sunday, March 16, 2014

Room:  Suffolk
Time:  8 am-5 pm  
Instructor:  Steven Whitmeyer, James Madison University

Google Earth is used by many geoscientists as a "geo-browser" to study Earth features as revealed by the Google Earth terrain model and imagery. Layers that come with Google Earth highlight features of special interest, but dedicated geoscience content is usually created by a small number of geoscientists who know how to program in KML, the language of virtual globes. This workshop will focus on methods that we have developed to help geoscientists create original content for Google Earth using familiar software such as web browsers, word processors, and image file collections. Case studies will include:   (1) Creating digital geologic maps with 3-D symbols, emergent cross sections, etc.; (2) Field data collection with iPads, etc. and integrating field datasets into Google Earth; (3) Optimizing digital geologic map and information for use in the field; and (4) animating surface processes and tectonic motions. Participants will need to bring their own laptops with Google Earth and ActivePerl installed (Mac users already have Perl). If available, participants are also encouraged to bring iPads with the Google Earth and GeoFieldBook apps installed.

SC-2:  Environmental Applications of the Induced Polarization Method
Date:  Sunday, March 16, 2014

Room: Wellesley
Time:  8:30am – 5:00pm

Instructor: Lee Slater and Dimitrios Ntarlagiannis, Rutgers-Newark, New Jersey  

Historically developed as a mineral prospecting method, the induced polarization (IP) geophysical technique has seen a resurgence of interest over the last two decades for environmental and engineering characterization/monitoring. This resurgence has primarily been driven by the recognition of the unique sensitivity of the IP method to pore-surface properties and processes, and the resulting implications for estimation of permeability and monitoring of geochemical or biogeochemical processes.  This one-day short course focuses on the developments in this extension of the DC resistivity method in response to the unique opportunities that exist to improve understanding of near surface (upper 100 m) properties and processes beyond that which can be achieved using resistivity measurements alone. The short course will cover: [1] recent theoretical developments and petrophysical relations; [2] practical advice on how to acquire and process meaningful IP data both in the laboratory and the field; [3] IP data processing and inversion strategies; [4] recent case studies in hydrogeophysics and biogeophysics.  Recent advances with the spectral induced polarization (SIP) method, whereby IP measurements are made over a wide range of frequencies to provide further information on the physicochemical properties of the subsurface, will also be described.

SC-3:  Overview of Utility Locating Technologies
Date:  Thursday, March 20, 2014

Room:  Suffolk
Time:  8 am - 5 pm

Instructor:   Ralf Birken, Northeastern University

Accurate locating and mapping of subsurface utilities is very important for utility owners, highway managers and engineers, designers, and contractors.  The lack of reliable 3D location information can have significant safety and economic consequences.  This short course provides an overview of existing utility locating technologies and methodologies.  The focus is on the complementary geophysical methods of electromagnetic induction (EMI) and Ground Penetrating Radar (GPR).  The following topics will be explored from a mainly practical point of view: Comparison of geophysical EM methods, fundamentals of EMI and GPR, single-channel versus array systems, survey strategies, importance of accurate positioning information, Dig Safe and similar services, Subsurface Utility Engineering (SUE), cost-benefit analysis, and case histories.  Many 3D GPR case histories will be presented for small and large scale locating projects.  A special section will explore the locating of deep conductive utilities.

SC-4:  Multichannel Analysis of Surface Waves (MASW) - Fundamentals Plus
Date:  Thursday March 20, 2014
Room:  Wellesley
Time:  8 am - 5 pm  
Instructors:   Choon Park, Park Seismic LLC, and Mario Carnevale, Hager GeoScience, Inc.

For about a decade, MASW has become a significant tool for geotechnical site characterization, in which the measurement of shear-wave velocity (Vs) plays an important role.  During this period, training for and application of the MASW method, particularly in the U.S., has been software-driven.  In this course, we will enhance understanding of the MASW method by approaching the fundamental and advanced instructional topics from a conceptual standpoint, i.e., one not driven by software instructions.

The Vs of ground materials is the most valuable among the parameters used in calculating shear and Young’s (E) moduli used in foundation design.  The MASW method offers a cost-effective surface geophysical means of obtaining the Vs of ground materials that has traditionally been challenging because of the inherent difficulties in generating and recording shear waves with high signal-to-noise ratio (S/N) in borehole surveys.  The MASW method calculates Vs from surface waves, a dominant and easily recorded waveform in all seismic surveys.  The multichannel recording and processing approach adopted in the MASW method provides flexibility and robustness in data analysis, further enhancing accuracy of the results.

The first part of this course will cover the fundamentals of surface wave data acquisition, analysis, and processing that will allow participants to perform an MASW survey on their own.  We will show how MASW offers simple and easily applied procedures that can be used by most geo-professionals after minimal training.  

Despite the overall simplicity and high success rate of the MASW method, a MASW survey can sometimes produce results that fall below expectations.  Although there may be several reasons for this, the cause may simply be due to non-optimal field acquisition geometry, improperly chosen data-processing parameters, or misapplication of the method without acknowledging its limitations.  Avoiding these problems will increase the confidence level of MASW survey results for practitioners and clients alike.  

The objective of the second part of this course is to fully understand the inter-relationship between critical parameters in data acquisition and processing that influence the outcome of MASW surveys.  With this information, practitioners will gain more confidence in field operation and data processing, and improve their ability to accurately anticipate the outcome of a planned MASW survey. With successful MASW survey experiences, they will be able to face challenging situations more successfully.  

This course will present several actual case histories that illustrate successful, fair, and below-average MASW survey outcomes; i.e. The Good The Bad and The Ugly.  The critical aspects responsible for each outcome will be examined and discussed. Hands-on data collection will also be performed.
