2004 PSSAT Officers President - Ted Zobeck
| |
|
Dr. Richard Drees requested that the following letter be included in the next newsletter. We continue to wish (for him) health and prosperity and our deep appreciation for all his contributions.
I count it a privilege to have
been elected as President of PSSAT. This is a fine organization which has
many outstanding members and as a professional organization has
accomplished a lot over the years. As many of you may know, I had some
health issues last fall. I thought that after a heart valve replacement
that things would be back to normal. But complications which aggravated a
previous illness have kept me from full recovery. I feel that it is best
for PSSAT and my continued recovery that I resign as President of PSSAT.
Tod Zobeck, vice-president, has graciously agreed to fill in as president for the remainder of the year. He will do a good job, and has already initiated committee assignments that I was not able to do. So, give him all the support you can, and give a willing hand if asked to do some task.
I will continue to support
PSSAT and do all I can to further our profession. I look forward to seeing
you all at the next PSSAT annual meeting.
Sincerely, Texas A&M University | |

President's Letter ...Ted M. Zobeck PhD, NRCS-ARS The Professional Soil Scientists Association of Texas was established to foster the profession of soil science and to further the increase and dissemination of information concerning all phases of soil science in order to contribute to the general human welfare (from the Constitution Preamble). I firmly believe in these goals and am proud of our record of past achievement. It is an honor to be of service to PSSAT to foster these goals. As you may know, I began the year as Vice-President and looked forward to issuing membership cards to new members and performing the other duties of the office. However, our incoming president, Dr. Richard Drees , has had unexpected health complications and he felt it best to resign (see letter above). Article VII, section 3a of the Bylaws stipulates that the Vice-President shall perform all duties of the president in cases of disability. I am honored to serve as President of the Association and will do my best to perform the duties of the office. I pray for Richard’s speedy recovery and look forward to seeing him at all future PSSAT activities. As President, I will work closely with the other members of the PSSAT Executive Council: Vice-President Alan Stahnke, President-Elect Eddie Bearden, and Treasurer Kelly Atterbury. We have already appointed committees, as listed in this newsletter. Please contact any members of the Council if you have any questions about your committee duties. Let me know if you were not appointed but wish to serve on a committee. We need to know if you are interested. PSSAT’s work is done through the committees. I encourage all committees to work diligently to foster the goals of PSSAT and look forward to another successful year.

Smithsonian Exhibit Ted M. Zobeck, PhD, USDA-ARS We hope that by now you have been made aware
of an exciting new way to explain the importance of soils to millions of
people, the Smithsonian Soils Exhibit. The purpose of this exhibit closely
follows the purposes and goals of PSSAT and we are an important part of
this project. Well, what
is it? A group of soil scientists from around the country as well as here
in The State of
Texas Smithsonian Exhibit Committee includes Schematic Drawing of the Smithsonian Soils Exhibit

Riparian Soils and the National Riparian Service
Team In June 2002, I attended a phenomenal training on Proper Functioning Condition of Riparian Areas conducted by the National Riparian Service Team. Proper functioning condition (PFC) refers to a qualitative method for assessing the condition of riparian-wetland areas – it is a qualitative assessment based on quantitative science. The PFC assessment is a "consistent approach for considering hydrology, vegetation, and erosion/deposition (soils) attributes and processes to assess the condition of riparian-wetland areas". Interest in riparian areas caused the Agency heads of BLM and USFS (in March 1996) to sign a letter of agreement to "aggressively implement a cooperative management strategy to accelerate the restoration and improved management of riparian-wetland areas in the western United States . NRCS is a principal partner in this initiative. The National Riparian Service Team (and an extended coordination network) was then created to focus efforts on this approach to cooperative riparian restoration. The web site for the National Riparian Service Team is http://www.or.blm.gov/nrst/. The site provides several training materials, including PFC publications and Powerpoint presentations on Riparian Soils and Riparian-Wetland Areas. In addition, reference materials include the publication "Soil Bioengineering – An Alternative for Roadside Management". I had the good fortune to meet the author (Lisa Lewis, soil scientist) at NRCS training last year, and she also mentioned an upcoming publication on riparian soils. Riparian-Wetland Soils was published in September 2003 and is currently available through the National Riparian Service Team web site. Lisa and the entire team are strong resources and contacts for restoration and soils work in riparian areas.

New Technology – LIDAR Research
In general, topographic studies require researchers to select between localized, highly detailed information and less-accurate data that covers a broader area. A scarcity of rapid survey techniques has also limited researchers in their quest for topographic data with accuracies better than 30 cm and resolution of surface features smaller than 10 m. In Texas , these restrictions can affect survey work on low-relief areas of the Gulf Coastal Plain and the Southern High Plains. However, a new technology known as airborne LIDAR terrain mapping can provide both detailed and highly accurate topographic data covering a broad area. LIDAR data has a vertical accuracy of 10 cm and a data-point spacing of less than 1 m, allowing researchers to conduct geomorphic analysis across the continuum of spatial scale. Using laser technology, LIDAR (Light Detection and Ranging) mapping systems can assist in gathering topographic information, such as surface vegetation, buildings, and highways, at 10-to 20-cm accuracy and submeter data-point spacing. Advances in GPS (Global Positioning Systems) have facilitated the development of airborne LIDAR. Airborne LIDAR is a ranging technology that uses light instead of sound or radio waves. LIDAR uses optics in the laser system to scan the beam across the land surface along the aircraft flight path. For each individual pulse of the laser (25,000 times per second), the distance to the target from which the laser reflects is noted. Coincidentally, a sophisticated inertial measuring unit records the roll, pitch, and yaw of the aircraft. At the same time, GPS data are being collected both on the aircraft and at a reference point on the ground to determine aircraft position. Following the flight, these data are combined to yield the X, Y, and Z positions of the features that reflected the laser energy. This process generates a volume of data, and data processing is a significant part of any LIDAR survey. Following data acquisition, poor data is filtered out and calibration parameters are determined for each flight to provide the best X, Y, and Z positions. The resultant data are then used to create models known as Digital Terrain Models (DTMs). LIDAR data can also be fused with additional remote sensing data, including aerial photography, imaging RADAR, and multi- and hyper-spectral data, to improve land-cover classifications. The Bureau of Economic Geology (BEG) in Texas is currently investigating LIDAR applications along barrier beaches and coastal bays. This work will provide topographic models necessary for geomorphic analysis and delineation of shoreline features particularly susceptible to storm damage, analysis of shoreline retreat and overwash, and review of shifts in coastal habitats. The BEG is also investigating flood-hazard mapping, landslide mapping, and mapping for forestry evaluation or wildlife habitat. The BEG is also investigating use of ground-based LIDAR systems to study rock outcrops and complement (or replace) large and awkward photomosaics, cross-sections, and detailed measured sections as primary mapping and description tools. Is LIDAR in your future? (Text modified from Bureau of Economic Geology Midyear Report 2001 and Midyear Report 2003.) |
