The INSPIRE team is gearing up for a week of presenting our research and connecting with our clients, colleagues, and friends in New Orleans. We’ll be at the Ninth International Conference on Remediation and Management of Contaminated Sediments, presented by Battelle from Tuesday thru Friday (Jan 10-13).
Dr. S. Kersey Sturdivant will be presenting findings of research undertaken following the Deepwater Horizon accident in the Gulf of Mexico. His talk will take place on Tuesday at 1:50 pm in Grand Ballroom E.
Animal-Sediment Response to and Recovery from the Deepwater Horizon Accident: A Worm’s Eye View.
John Hardin will be presenting in poster group 2 at the Long-Term Monitoring Strategies poster session (A11 #33). John’s poster will be displayed from Wednesday through 7:00 a.m.–Thursday 1:00 p.m. Presentations/Reception Wednesday, 5:45 p.m.–7:00 p.m.
Short- and Long-Term Recovery of Benthic Communities Following Dredge Material Disposal: A Case Study of the LA-3 Dredged Disposal Site.

If you are in New Orleans this week, please get in touch, we’d love to see you!
Those who are interested in learning more about INSPIRE Environmental have another chance to meet our scientists at the Oceanology International Conference 2017, from Feb. 14 – 16 in San Diego, CA. INSPIRE will be exhibiting a booth and Dr. Drew A. Carey will present a talk on the importance data visualization.
As one of the developers of the technology, we had the privilege of introducing it to the government of Hong Kong in 1993, and it became a key component of the 4-year, territory-wide monitoring program associated with the massive dredging/land reclamation that was a key part of the new Chep Lap Kok airport construction. We introduced the technology in many areas outside the United States (Canada, Ireland, Italy, New Zealand, China, Azerbaijan). SPI is a powerful technology that provides an innovative and cost-effective solution to many marine environmental monitoring programs.
What Sediment Profile Imaging can Measure
Sediment Profile Imaging allows rapid data acquisition during field sampling (the camera is literally “pogo-sticked” across the seafloor). A wide variety of physical and biological parameters can be measured from each image.
Grain-size major mode and range (gravel, sand, silt, clay).
Small-scale surface boundary roughness.
Evidence of erosional or depositional environments, allowing identification of high and low kinetic energy areas.
Subsurface methane gas pockets (evidence of high Sediment Oxygen Demand).
Depth of the apparent RPD (Redox Potential Discontinuity).
Calculation of the Organism-Sediment Index, allowing rapid identification and mapping of disturbance gradients in surveyed areas.
Presence of epifauna.
Surface microbial aggregations.
Infaunal Successional Stage.
Evidence of excess organic loading and high sediment oxygen demand.
Benefits of using Sediment Profile Imaging:
Because traditional seafloor sampling techniques are expensive and time-consuming, an efficient sampling strategy for surveys can be an enormous aid to an efficient survey. SPI aids in determining the location of traditional sampling stations by rapidly characterizing the variation in benthic sedimentary and community conditions. Limited sampling resources can be allocated to the optimum sampling locations to accurately characterize the variance that exists in a particular area. All too often the results of monitoring programs show that a particular parameter of interest has either been over- or under-sampled as a result of “flying blind” initially and then sticking with the initial station locations that were chosen arbitrarily from a nautical chart.
Rapid and cost-effective data collection and analysis
SPI can survey large areas of seafloor quickly and efficiently. For many monitoring objectives, SPI technology can provide the necessary answers without the need to collect grab samples or repeatedly enumerate and identify individual invertebrates and assemble long species lists each time a sampling study is performed.
Gradient delineation between sampling locations accurately
Because the camera can obtain pictures rapidly and efficiently, it can supplement traditional sampling methods. SPI achieves this by “filling in the gaps” between traditional chemical and biological sampling locations. The camera can accurately delineate gradients in biological community type, organic loading, or sediment grain-size between fixed station locations.
Results that are easily understandable by a non-scientific audience;
Many environmental programs have suffered because of their inability to convey results to regulators or a public audience who may not have a marine science background. One of the camera’s most powerful attributes is its ability to convey ecological information in an easily understandable format: a picture.
Over the past 10 years, we have come to realize that the technology’s most powerful asset is this last item. SPI was able to provide the decisive evidence in several environmental litigation cases concerning ocean disposal impacts. SPI technology proved that impacts were transitory and a full ecosystem recovery had taken place.
