REPRESENTATIVE
PROJECT EXPERIENCE
HYDROGRAPHY
Field Manager / Technical
Manager, Bathymetric / Sub-Bottom
Surveys, Phosphorus Flux and Sediment Evaluation, New York City DEP
Reservoirs, Catskill / Delaware Watersheds, New York (Ashokan, Schoharie,
Cannonsville, Pepacton, Neversink, Rondout and West Branch Reservoirs).
The goals of this project were to evaluate post-construction
sedimentation rates and the role of sediments in reservoir nutrient dynamics. To determine sedimentation, high-precision
bathymetric and acoustic sub-bottom surveys of seven large (total area of 1,025
km2) water supply reservoirs in the Catskill/Delaware watersheds of
central New York State were conducted.
To evaluate sediment/water column nutrient dynamics, approximately 1,000
surficial sediment samples were collected and analyzed for pertinent physical
and chemical parameters. Nearly 300
intact sediment cores were collected for microcosm-scale evaluation of sediment
oxygen consumption rates and phosphorus release. The project demonstrated that brief periods of anoxia were
unlikely to result in P release, and suggested that manipulation of
hypolimnetic volume could be a useful water quality management tool.
Mr. Wright was the lead technical expert and field manager of a field
staff that varied between four to six people depending upon short-term workload
requirements. Mr. Wright was
responsible for performing and overseeing day-to-day operations having to do
with state-of-the science on board data acquisition for the bathymetric survey
and sub-bottom sediment profiling, collection of sediment grab samples for
nutrient analyses and collection of undisturbed sediment cores and incubation
of the cores in a field laboratory for measurement of phosphorus release
P-release and sediment oxygen demand.
Mr. Wright performed all of the hydrographical/geophysical data
reduction, analysis and presentation for the project.
Hydrographer / Oceanographic
Technician, NOAA
Soft-Bottom Trawl Impact Study.
In June 2001, CR Environmental, Inc. began
conducting research on fishing gear-induced habitat impacts to soft bottom
habitats in Massachusetts Bay off Scituate, Massachusetts. Mr. Wright was responsible for acquisition
and interpretation of side-scan sonar data, bathymetric mapping, collection of
benthic biological samples, and developing and maintaining a GIS database for
the project. To date, much of the
research on fishing gear-induced habitat impacts focuses on long-term
cumulative changes to gravel bottom or rocky substrate communities in areas
open to or closed to fishing activity. Because little is known of the
historical distribution and density of fishing activity in the open area, it is
difficult to quantify the impact of fishing per unit of effort. Using local
fishermen’s knowledge, open soft bottom areas subject to low and high
intensities of trawling and at similar depths were characterized before and after
repetitive passes of smooth bottom net trawl fishing gear. Areas were surveyed
for benthic infauna, epifauna, sediment surface characteristics, water column
parameters, and fish. Fish stomach
contents and invertebrates were tallied after each of six repetitive trawls.
Four southeastern Massachusetts fishing vessels and six or more fishermen
participated in much of the data collection and preliminary processing with
oversight and training from technical experts.
Marine biologists and oceanographic technicians will analyze the data
with input from the fishermen and a final report will be prepared. Such
information could improve predictive capabilities in fisheries management for
soft bottom habitats, and allow managers to better determine how much fishing
can be sustained there and the effectiveness of rotating versus permanent area
closures.
Field Manager
/ Senior Hydrographer, Colorado River/Hoover
Dam Bathymetric
Surveys. Under contract
to Ladd Construction, Inc., CR was charged with conducting pre- and
post-construction bathymetric surveys of a reach of the Colorado River
immediately downstream of the Hoover Dam, beneath the alignment of the new
Hoover Dam Bypass Bridge which
spans the Black Canyon between Arizona and Nevada. The goal of the
surveys, conducted in 2005 and 2006, was to model the volume of material
deposited in the river during blasting of the canyon walls for
construction of anchoring structures. Project challenges included
navigation to the Site from a launching point about 14 miles downstream,
overcoming positioning uncertainty associated with work deep in the Canyon, and
acquisition of reliable soundings in the highly irregular currents and variable
depths below the Hoover Dam. Mr. Wright designed and executed a precision
single-beam bathymetric survey which met the Project's needs and presented
volume calculations which documented the relatively small volume of
construction-related debris deposition. All work was approved by Project
Engineers, the U.S. FHA and the BLM.
Field Manager / Senior Hydrographer, NOAA/NMFS Essential Fish Habitat Hydrographic & Geophysical Surveys. 2004. The objectives of this project were to locate areas known by the fishing industry to support high fish productivity and then evaluate the physical and biological attributes of these sites to gain some insight as to why the areas might be considered essential fish habitat. Two sites were chosen based on the recommendations of fishermen and geophysical characteristics. These sites were surveyed using swath bathymetry, towed side scan sonar, sub-bottom profiling sonar, and CR's video sled. Mr. Wright was responsible for survey design, data acquisition & processing, and integration of all data into a coherent GIS database.
Field Manager / Senior Hydrographer, Lower Fox River Side Scan Sonar Archaeological Survey, De Pere, Wisconsin. 2006. Under contract to Shaw Environmental, Inc., CR & Mr. Wright performed a pre-dredge side scan sonar survey of a very shallow Operable Unit in the Lower Fox River. Although water depths rarely exceeded two feet, an unconventional deployment of the towfish allowed reliable target identification and substrate characterization to about 10m range.
Field Manager / Senior Hydrographer, Hydrographic & Geophysical Surveys Supporting the East River Tide-Energy Project. Between 2005 and 2006, Mr. Wright has led CR teams conducting bathymetric, side scan sonar and sub-bottom sonar surveys of the East River, NYC in support of the siting and installation of generation turbines for the initial pilot demonstration phase of this project. Other work is currently scheduled for expansion of the survey area in 2007.
Field Manager / Senior Hydrographer, "The Lake" at Central Park, NYC Hydrographic & Geophysical Surveys. As part of the New York City Central Park Conservancy's effort to restore The Lake, Mr. Wright lead a CR team which mapped the water depth and sediment thickness of this shallow urban pond.
Field Manager / Senior Hydrographer, Quinnipiac River Hydrographic & Geophysical Surveys. Under contract to URS, Inc., Mr. Wright led a survey team charged with measuring scour beneath an I-95 overpass in support of bridge design efforts, locating sub-sediment utilities, and exploration of the sub-surface along a proposed large utility alignment. Detailed bathymetric maps, side scan sonar mosaics and maps of magnetic anomalies were provided to project engineers shortly after completion of the field work.
Field Manager
/ Senior Hydrographer, Connecticut River Bathymetric
Surveys.
Mr. Wright directed the acquisition and processing of high precision bathymetric data for a 100-mile reach of the Connecticut River. This CR survey effort was conducted under an ENSR contract for FEMA. Over 350 transects were surveyed along reaches of the Connecticut River between White River Junction, Vermont and the Massachusetts border.
Lead
Hydrographer, Geophysical Surveys of the Delaware River, Bordentown, New
Jersey. In support
of a feasibility study for construction of a large scale power plant on the
bank of the Delaware River, CR Environmental conducted bathymetric, side scan
sonar, acoustic sub-bottom, and magnetic surveys of the Bordentown and
Whitehall Reaches for ENSR International, Inc.
Mr. Wright was responsible for directing acquisition, processing and
presentation of all geophysical data.
Project Limnologist /
Hydrographer, Lake Quinsigamond and Flint Pond Drawdown Feasibility Evaluation. As an integral facet of an evaluation of potential management
techniques for nuisance aquatic vegetation control, Mr. Wright conducted
surveys of aquatic vegetation, bathymetry, and sediment thickness. The surveys allowed calculation of exposed
bottom areas and potentially impacted vegetation for several drawdown
scenarios. The surveys also allowed
estimation of the rate of dispersion of nuisance species through comparisons
with earlier studies.
Jamaica
Bay Bottom Mapping and Remote Benthic Habitat Characterization - Little
Bay, Norton Basin, Grass Hassock Channel and Raunt Channel, Jamaica Bay, New
York. CR
Environmental performed multibeam bathymetry, side-scan sonar, video sled
trawls and RoxANN acoustic bottom surveys for two target basins and two
"reference" basins in Jamaica Bay, New York. Mr. Wright was responsible for
interpretation and presentation of the majority of remote sensing data. CR provided digital and hard-copy versions
of all deliverables, including over 25 scaled survey maps and side-scan mosaics
depicting dominant habitat types, bathymetry and underwater structures such as
ship wrecks. CR also provided project
scientists with accurate hypsographic/volume calculations for each of the
target basins and AutoCADD and ArcView GIS versions of survey data. The surveys were conducted aboard R/V
Cyprinodon.
Consulting Field
Hydrographer / Geophysicist, New Bedford Harbor/Acushnet River
Bathymetric/Sub-bottom Surveys and Vibracore Sediment Sampling. Working as a sub-contractor for CR Environmental,
Mr. Wright provided on-site supervision of bathymetric and sub-bottom survey
operations of this Superfund Site.
Following survey operations, Mr. Wright assisted with collection of
sediment cores. The surveys and samples
were used by EPA sub-contractors in their investigation of the extent of PCB
contamination and possible remedial alternatives.
Field Director, Phase II Sediment
Investigation, Cayuga Inlet, Ithaca, New York. Working as a liaison between CR Environmental and Woodard &
Curran, Inc., Mr. Wright designed and managed a multi-phased
technology-intensive investigation of sediment contamination in Cayuga Inlet,
the largest tributary to Cayuga Lake.
The investigation was designed to determine whether a former MGP facility
had contributed to sediment contamination.
The assessment included detailed mapping of water depth and sediment
thickness, vibrocoring, and several innovative analytical methods. Mr. Wright was responsible for all phases of
data acquisition, analysis and presentation, as well as contribution to a Fish and
Wildlife Impact Assessment in accordance with NY DEC guidance.
Field Hydrographer /
Geophysicist, Housatonic River Bathymetric and
Sub-bottom Surveys - Woods Pond and Rising Pond. Working as a sub-contractor to the ecological science team at CR
Environmental, Mr. Wright performed bathymetric and sub-bottom surveys of two
large impounded ponds on the Housatonic River.
The surveys resulted in accurate estimates of sediment accumulation in
the ponds, and aided EPA sub-contractors in their investigation of the extent
of PCB contamination and possible remedial alternatives.
Field Hydrographer /
Geophysicist, Mamaroneck Harbor Sub-bottom Survey - Mamaroneck, NY, New York District
Army Corps of Engineers, Operations Division.
Working as a sub-contractor to the marine
science team at CR Environmental, Mr. Wright performed a sub-bottom survey of
Mamaroneck Harbor, New York for the operations branch of the New York Army Corps
of Engineers. The purpose of the survey
was to map the sub-bottom layers of harbor sediments to aid in the planning of
dredging operations. The Edgetech
X-STAR sub-bottom profiler was utilized to collect the acoustic sub-bottom
data. Cross-sectional plans of
sub-bottom layers were furnished as final products.
Bathymetric Survey of Springton Lake / Geist
Reservoir, Media, Pennsylvania. In June 2000, Mr. Wright
performed a detailed bathymetric survey of
Springton Lake, a water supply reservoir for the Greater Philadelphia
region. The work was performed for the
Philadelphia Suburban Water Company (PSWC) to support limnological and water
quality investigations. CR mobilized
survey equipment to a small vessel provided by PSWC. The survey was conducted using HYPACK survey software, a Raytheon
DE719 MKII digital fathometer equipped with a 3-degree 200 kHz transducer, and
a 12-channel Trimble DGPS. In addition
to scaled plans, data were delivered to project scientists in GIS format.
Field Hydrographer /
Geophysicist, Fort Point Channel Sub-Bottom Investigation - Boston,
Massachusetts. Mr. Wright applied a Datasonics low-frequency Chirp sonar in a
sub-bottom search for “grout blisters” associated with an underground MBTA rail
line. The survey was successful, and
subsequent dredging operations in the channel were able to avoid these
submerged features, disturbance of which could have resulted in substantial
harm to the railway.
Field
Hydrographer / Geophysicist, Allen Harbor
Bathymetric Survey - Davisville, Rhode Island. Working as a sub-contractor
to the marine science team at CR Environmental, Mr. Wright was the senior
hydrographer for three high precision pre-dredge and post-dredge bathymetric
surveys of the channel connecting Allen Harbor with Narragansett Bay. The project provided our client with
accurate estimates of the volume of dredge material removed, and confirmed that
the dredged channel met ACOE specifications.
Evaluation of Nutrient Loading and Eutrophication Potential of Long Sought for Pond, Westford, Massachusetts. Mr. Wright conducted a two-year water quality evaluation of a large glacial pond, including in-situ measurements of several biological and chemical parameters, deep-core sediment sampling, historical analysis of lake conditions using diatom remains in sediment, and in-depth hydrological analysis. The goal of the project was to evaluate the potential for adverse impacts due to non-point source phosphorus inputs which might result from future shoreline development. The evaluation used mass-balance calculations of P-loading as inputs to models of lake responses to nutrients to estimate current and acceptable P-loading rates. The project concluded that the effects of basin morphometry upon in-lake water circulation had limited lake responses to current P inputs, but strongly suggested that additional loading could result in rapid eutrophic response.

ECOLOGICAL RISK ASSESSMENT
Project Ecologist, Former
Rutland State Hospital MCP Site, Rutland, Massachusetts..
Designed and implemented a
comprehensive Stage II Ecological Risk Characterization (per Massachusetts MCP)
to address potential impacts to a stream and wetland exposed to several heavy
metals. Using a triad approach to sediment quality assessment (bulk
toxicity testing, AVS/SEM analysis & macroinvertebrate bioassessments), the
ERC conclusively demonstrated that metals were unlikely to harm receptor
organisms.
Project Ecologist/Taxonomist, Hampshire Chemical Company,
Nashua, New Hampshire. Assisted in the
design and implementation of a comprehensive ecological risk characterization
program for the Merrimack River. The
project was designed to evaluate potential impacts to fishery resources. The study incorporated extensive sampling of
sediment boundary layer water, sediments and three rounds of quantitative and
qualitative benthic macroinvertebrate sampling. The natural substrate of the river was sampled for invertebrates
using a custom built dredge. Artificial
substrates (rock baskets) designed to eliminate substrate variability were
deployed at the river bottom, and grab samples were collected from near shore
areas. As the principal invertebrate
taxonomist/ecologist for the project, Mr. Wright met or exceeded EPA
Science Advisory Board recommendations for taxonomic resolution. The project demonstrated, based on analyses
of the biological data, that site-related impact to fishery resources in the
Merrimack River was unlikely.
Project Ecologist, Confidential Client, Waltham,
Massachusetts. Investigated the potential
ecological impact of the slow release of over 1 million gallons of PCB and
heavy metal contaminated waste oil to a 15-acre wetland. The assessment involved extensive sediment sampling
and qualitative/quantitative evaluations of soil invertebrate and stream
invertebrate communities. Data analysis
techniques included the equilibrium partitioning approach, effects-level
screening, and modeling of bioaccumulative compounds and heavy metals through
terrestrial and avian wildlife food chains using measured and predicted body
burdens of chemicals in earthworms. Based on invertebrate data, it was
demonstrated that portions of the soil invertebrate community had been
impacted, although the aquatic invertebrate community had not.
Project Ecologist/Taxonomist, Confidential Client,
Concord, Massachusetts. As an integral
portion of a MCP Stage II Ecological Risk Assessment, Mr. Wright developed and
implemented a comprehensive biological survey of the aquatic and soil (peat)
invertebrate communities of an ombrotrophic peat bog contaminated with uranium
and copper. No impact to invertebrate
communities was observed.
Project Ecologist, Confidential Client, Hanover,
Massachusetts. Conducted an initial MCP
Method 3 Stage I screening level environmental risk assessment of an extensive
wetland system which had been contaminated with silver. This initial assessment suggested that
ecological receptors were likely to be harmed by exposure to contaminated
wetland soils. During the Stage II
ecological risk assessment which followed, Mr. Wright served as the
principal taxonomist for wetland soil invertebrates. The biological data collected demonstrated that the soil
invertebrate community had not been impacted by exposure to silver.
Project Ecologist/Taxonomist, Confidential Client,
Orange, Massachusetts. Conducted a
bioassessment of the benthic macroinvertebrate community in a headwater stream
in which concentrations of hexavalent chromium exceeding U.S. EPA Ambient Water
Quality Standards had been detected.
This bioassessment demonstrated that the study stream supported a
benthic community similar to a nearby reference stream, proving that the chromium
had not caused “gross” impairment to stream biota.
Project Ecologist, Confidential Client, Andover,
Massachusetts. Conducted a bioassessment of
the benthic macroinvertebrate community in a small stream in which
concentrations of lead and copper exceeding U.S. EPA Ambient Water Quality
Standards had been detected. This
bioassessment demonstrated that the study stream supported a benthic community
similar to a nearby reference stream, proving that the metals had not caused
“gross” impairment to stream biota.
Project Ecologist, Norwood PCB Superfund Site. Mr. Wright developed a defensible Maximum
Acceptable Sediment Concentration (MASC) for PCBs in the sediments of a stream
adjacent to this CERCLA site. The MASC
was based on bioconcentration / bioaccumulation modeling of PCBs through the
food chain using raccoons as receptor organisms.
Project Manager / Ecologist, Veryfine Corporation,
Westford, Massachusetts (U. Mass. Lowell Research Foundation). Mr. Wright coordinated and conducted
extensive benthic macroinvertebrate sampling, taxonomy and statistical data
analysis of biological, chemical and physical parameters to quantify the
effects of treated industrial effluent on the receiving aquatic
ecosystems. Mr. Wright collected and
identified benthic macroinvertebrate samples from two streams and a pond, as
well as sediment and water samples to monitor water quality parameters. Using ecological indices of community health
and statistical analyses of water quality data, Mr. Wright demonstrated
Veryfine's compliance with NPDES discharge limits. In fact, Veryfine's discharge was shown to maintain water flow
during periods of negligible natural discharge, thereby sustaining a community
of aquatic organisms throughout the summer months. Subsequent to the project's
completion, Veryfine received local, state, and national environmental awards.
Project Manager, Evaluation of Nutrient Budget and
Eutrophication Potential of Long Sought for Pond, Westford, Massachusetts. Conducted a two-year water quality evaluation
of a glacial pond, including in situ measurements of several biological and
chemical parameters, deep-core sediment sampling, historical analysis of lake
conditions using diatom remains in sediment, and in-depth hydrological
analysis. The aim of the project was to
evaluate the potential for adverse impacts due to non-point source phosphorus
inputs. The mass balance calculations
presented in the report demonstrated potential risk of eutrophication due to phosphorus
inputs.
