Integral Staff to Present at the 22nd Ocean Optics Conference in Portland, Maine

Integral Consulting Inc. scientists will lead poster presentations during the 22nd Ocean Optics Conference in Portland, Maine, on October 26–31, 2014. The six-day conference, sponsored by The Oceanography Society, is expecting to draw more than 350 oceanographers, marine ecologists, optical engineers, marine resource managers, policy professionals, and oceanography students from around the world.

Managing Scientist Grace Chang, Ph.D., and Principal Todd Martin, P.E., will present posters about their work at the Berry’s Creek Study Area (BCSA), a 12-square-mile, watershed-based Superfund site in the New Jersey Meadowlands. Dr. Chang’s poster, “Optical Methods for Quantifying Biogeochemical Variability in a Tidal Estuary,” was co-authored with Todd Martin, Principal Craig Jones, Ph.D., and Scientist Frank Spada. The poster examines a pilot study that used optical instrumentation to predict concentrations of chemicals of potential concern in the BCSA. Among the study’s results was the first-ever determination of PCBs from in situ optical properties. The study also showed that optical properties are good predictors of unfiltered and particulate mercury and methyl mercury present in waterways.

Todd Martin’s poster, “Optically Based Determinations of Biogeochemical Variability in a Tidal Estuary,” was co-authored with Grace Chang and Craig Jones. His poster illustrates how a partial least square regression model using optical properties was successfully developed and used to predict organic and chemical concentrations in the BCSA during a spring tide period. Results of the study also show that variability of dissolved mercury and methyl mercury were associated with tidal fluctuations and marsh exchange processes.

Brandon Sackmann, Ph.D., will present a poster titled “Optics from Ferries as Ground Truth for Satellite Ocean Color Products in Puget Sound.” It extends Integral’s work with Washington State Department of Ecology and the Applied Physics Laboratory at the University of Washington in developing en route ferry monitoring systems in Puget Sound. The poster illustrates how a combination of ferry observations and satellite ocean color data can produce synoptic assessments of key water quality variables that would be difficult to obtain through traditional shipboard sampling techniques.

Dr. Chang, who is also on the Ocean Optics XXII conference planning committee, will chair Oral Session 3 on Tuesday, October 28, from 8 to 10 a.m.

The schedule for the poster presentations are as follows:

Tuesday, Oct. 28, Poster Session 2, 10:30 a.m. to Noon
