MESSAGE FROM THE PRESIDENT

Welcome to our first issue of the Woods Hole Group Newsletter for 2009.  The global economy is in turmoil, to be sure, but we hope that the leadership of the United States and the rest of the world will help us find safe harbor for the global community.  Meanwhile, we at Woods Hole Group endeavor to provide the best services to our customers around the world. 

We are coming off a great 2008, and our forecast for 2009 is strong due to our diversified customer base. We also are pleased to report that we have recently been awarded a 5-year, $15 million contract with the U.S. Army Corps of Engineers. This month, we have three new articles for the newsletter.  The first two demonstrate how we use our scientific and engineering expertise in service of industry customers.  The third details significant upgrades to our technical infrastructure - improvements that will allow us to better serve our clients in 2009 and beyond.

Bruce Magnell has written an article on the CASE-EJIP ADCP Intercomparison project, supported by the Joint Industry Project group headed by Chevron, describing the results of test deployments of 75kHz ADCPs and intercomparison current meters in deep waters of the Gulf of Mexico.  The results of this multi-sensor comparison study revealed interesting new conclusions on the performance and application of these instruments in deep low-scattering waters.

Kirk Bosma writes about wetland restoration and numerical modeling.   As the public becomes more aware of the importance of wetlands to the environment, more work is going to be undertaken in restoration of these critical assets.  One of the challenges in restoring impacted systems is assessment of the evolution of the system, and subsequently, projecting what changes in habitat may occur as a result of restoration activities.  Restoration of the wetland, and specifically the alteration of the system hydraulics, often will result in a wide variety of potentially damaging changes.  Kirk discusses the role of numerical modeling in assessing these changes and designing projects to maximize the positive benefits while minimizing potential negative impact.

Woods Hole Group’s master of IT infrastructure, Darren Mansfield (known here in Falmouth as “Doctor D”), describes the latest changes to the Company’s work environment after a year-long overhaul.  I think you’ll find that our internal technical capabilities are extremely sophisticated, which allow us to function efficiently and in a protected data environment.  I hope to be able to report later this year on similar changes to our intranet environment where customers and employees can share information and processes. We've also launched our new website, which we encourage everyone to visit.

It is my pleasure to announce that the 2008 Woods Hole Group “Employee of the Year” is Dave Walsh.  Dave has become one of the stars of our world here, bouncing back and forth from coastal geology to field work in the deep ocean.  He has excellent client and project management skills and we look forward to many more years of his service.  And finally, I would like to thank our customers, vendors, partners and friends for their continued support of Woods Hole Group, and to offer you all our best wishes for productive and prosperous 2009!

President



BREAKING WAVES
News from our Coastal Sciences, Engineering & Planning team spotlighting the coastal zone.

Coastal wetlands play a critical role in the overarching coastal/estuarine environment.  While the scientific community has long recognized the importance of coastal wetlands, their values, and their relationship to estuarine ecosystems, it is only recently that the general public has begun to understand their importance.

Due to the lack of understanding, many wetland systems have been severely impacted by anthropogenic activities, such as the construction of roads, railroads, and housing developments, and have ultimately become severely degraded.  As such, many wetland areas are in need of restoration to return to their integral role in the ecosystem. One of the challenges in restoring these impacted systems is assessment of the evolution of the system, and subsequently, projecting what changes in habitat may occur as a result of restoration activities.


Restoration of the wetland, and specifically the alteration of the system hydraulics, often will result in a wide variety of potential impacts. These impacts include the potential for upland flooding and salt water intrusion, the change or loss of certain habitat areas (e.g., waterfront feeding, anadromous fish migration, among others) or vegetative systems, modification to the tidal exchange, alteration of surface and ground water quality and salinity levels, and potential impacts on the beach/inlet system. 

Addressing the concerns of stakeholders and regulatory agencies is often a balancing act that requires the project proponent to develop an accurate projection of the changes that will occur as a result of the restoration project.  Numerical modeling of these systems provides the ability to assess potential changes, evaluate a range of potential restoration alternatives, and is a cost-effective method to optimize designs, reduce construction costs, and ensure a successful project.

Numerical modeling of a wetland restoration project offers significant advantages, including:

  • More detailed quantitative information than can be obtained cost-effectively in a field data collection program alone

  • Long-term time series of important physical characteristics (e.g., water elevations, tidal velocities, hydroperiods, wetting and drying times)

  • Ability to simulate a wide range of natural occurring conditions (spring tides, storms, etc.)

  • Utility as a valuable engineering tool to evaluate a wide range of restoration alternatives and subsequent design requirements (e.g., changes to salinity levels, inlet scour, culvert and constrictions, fish passage, etc.).

herring river modelHowever, numerical modeling of a tidally-forced wetland system is not straightforward.  There are a wide variety of hydraulic, hydrologic, and hydrodynamic models available, ranging from simple to complex, and from proprietary to community, but not all are applicable for tidally-forced, marsh restoration projects.


marsh constructThe correct model selection, which includes consideration of the dominant physical processes and driving factors within the wetland system, is a key component of the numerical modeling process.  For example, depending on the physical system, the model selection process should evaluate the need for the model to appropriately simulate wetting and drying of a marsh surface, salinity levels, potential stratification, control structures (e.g., culverts, dikes, weirs, etc.), flow resistance due to various vegetation types, upland flooding, and/or storm impacts.  Ultimately, the model developer must understand the abilities and utility of each model prior to selecting the appropriate model for the restoration project. You need the experience and flexibility to select the right tool for each job.


Woods Hole Group has 20 years of tidal wetland restoration and monitoring experience, and our approach has been founded on:color-contours

  • Establishing clear restoration objectives.

  • Ensuring that adequate baseline data area collected.

  • Determining the right analysis techniques and models to implement.

  • Working with the stakeholders to develop potential alternatives.

  • Accurate modeling of existing conditions and alternatives.

  • Engineering design of the preferred alternative.

  • Construction, monitoring, and adaptive management.

Using this approach Woods Hole Group supported the largest privately funded restoration project in the United States, consisting of restoration of over 10,000 acres of marsh in Delaware Bay (Estuary Enhancement Program by PSEG). Currently, Woods Hole Group is working on restoration and modeling projects for the Herring River Estuary System in Wellfleet, MA, the Stony Brook System in Brewster, MA, the Bride Brook System in East Lyme, CT, and the Town Creek System in Salisbury, MA. These projects all included a model selection and development task to help identify and simulate proposed alternatives for the restoration.

 


THE DEEP BLUE
News from our Oceanography & Measurement Systems team spotlighting the open seas, ports, and harbors.

The Teledyne-RDI 75kHz Long Ranger ADCP (LR-75) is capable of obtaining ocean current profile measurements over a range of more than 500m under optimum acoustic conditions.  The deep-water version of the LR-75 was until recently the only commercially available technology for obtaining long-range current profiles in very deep water, and has been widely used in the offshore energy industry.  However, in recent years the offshore industry has limited use of the LR-75 for deep (>1500m) ocean measurements based on anecdotal reports of greatly reduced range and degraded accuracy.  This was thought to be due to a low density of acoustic scatterers in deep water, which reduces the backscatter signal strength used by the ADCP to estimate the Doppler shift associated with the water motion.   

To better understand the performance of the LR-75, WHG developed a proposal to the joint industry group CASE-EJIP for a multi-sensor intercomparison study in deep, low-scattering waters of the Gulf of Mexico. 


Location of the intercomparison study in the Gulf of Mexico.

The study was carried out during June-November 2006 at Chevron’s Cat Deep wellsite (Mississippi Canyon Block 782) in water depth of about 2000m. Two LR-75s and a 300 kHz Workhorse Sentinel ADCP (WHS-300) were deployed by ROV for three 1-month intervals in bottom tripods approximately 65m away from the wellhead of an exploratory drill rig.  The ADCPs were oriented so that none of their four main acoustic beams intersected the rig’s vertical riser.   Intercomparison current meters whose performance was known from previous studies were deployed on a 500m tall subsurface mooring about 1 km away, including 5 Nortek Deepwater AquaDopps, an Aanderaa RCM-11, and a 1200 kHz T-RDI ADCP.  Most of the instruments worked and gave apparently valid data, although significant differences in instrument performance were observed.  Analysis showed that currents were nearly homogeneous in the vertical above about 100 meters above bottom (mab), while frequency-dependent bottom intensification was observed in the range of 0-100mab. 

Despite the low density of acoustic scatterers, the LR-75s gave apparently valid data out to a range of more than 350m above bottom, as evidenced by the ADCP’s quality control parameters (high Correlation Magnitude combined with a realistic gradient of Echo Amplitude).  However, the intercomparison showed that the measured velocities from both LR-75s were significantly low-biased in all depth measurement cells (bins), out to the farthest measured range.  The speed deficit ranged from nearly 100% in bins close to the ADCP, to more than 10% in bins several hundred meters away.  The low bias error is inferred to be due to the ADCP’s reception of spurious scattered or reverberated side lobe signals from the rig’s nearby steel riser.  The acoustic beam pattern of the 4-beam LR-75 is such that side lobe energy may be returned from a nearby vertical object, such as a riser, over a time interval corresponding with many range bins. In any range bin, the amplitude of side lobe reflections or reverberations may be significant relative to the weak backscatter signal from scatterers in the water column.  The spurious side lobe signals are correlated with the transmitted signal but have zero Doppler shift, so when this correlated “noise” is mixed with the weak backscatter signal from scatterers in the main beams, the ADCP reports a low-biased speed.  Such a correlated-noise error cannot be detected by the ADCP itself, nor can the error be corrected in post-processing.

Temporary removal of the oil rig’s riser due to an approaching hurricane provided an opportunity to directly confirm the importance of side lobe interference.  In the absence of the riser, LR-75 velocities in mid-range bin were not low-biased compared to a reference current meter at comparable depth, whereas they were significantly low-biased immediately prior to removal of the riser and after the return of the riser.

Comparison of hourly-average current speed measured by LR-75 #6243, Bin 8 (265mab) versus reference current meter AquaDopp #2303 (260mab) with riser present (red) and with riser removed (blue).

This study showed that when an LR-75 is deployed in a deep, low scattering environment in close proximity (<500m) to a large vertical non-moving object such as a riser, significant underestimation of current speeds will result due to side lobe interference.  There is no possible orientation of an upward-looking four-beam ADCP that will avoid this side lobe interference.  If deployment of an LR-75 in the vicinity of a riser cannot be avoided, Teledyne-RDI recommends physically disabling one of the four beams and orienting the disabled beam toward the riser, in order to minimize the strength of side lobe echoes due to the other three beams and permit unbiased current measurements.  However, this configuration was not tested in this study, and its effectiveness cannot be predicted from the results of this study.

HOUSTON SPOTLIGHT

The year 2008 can be characterized by both a high volume of bids submitted and more importantly a number of challenging awards.
 
A project was initiated in February to measure near bottom currents in a furrow field in the deep Gulf of Mexico (~2800m).  For this project six instrumented bottom frames were precision deployed with a ROV at selected sites in four furrows.  To keep vessel costs low, data were successfully downloaded acoustically from the frames four and eight months after deployment.  The frames and instruments will be retrieved early this year using acoustic releases at the end of the 12 month deployment period.
 
A year-long coastal measurement program was deployed on the east coast of the U.S., which includes measurements from bottom platforms, subsurface moorings and surface moorings.  This program focuses on detailed current, wave and density measurements.

A year-long measurement program on the North Slope of Alaska began in August.  The program includes measurement of waves, currents and ice thickness from instruments mounted in bottom frames at three sites.
  
A year-long full column, current measurement program at a deepwater site in the Gulf of Mexico was also been awarded and deployed in July.  A second four-mooring program was deployed in December on behalf of a joint industry group.  That deployment cruise was conducted cost effectively through cost sharing of a service visit to the first mooring program.

We were also awarded a contract to design, build and install ADCP moonpool deployment systems on two new-build drillships over the next two years.  The design phase of this project is winding up and will be quickly followed by fabrication, installation and maintenance.  Such systems compared to the more common method deployment of ADCP’s ‘over-the-side’ include improving data quality and reducing risks of equipment damage and loss.
  
A desk study of currents and water temperatures in the northeastern Gulf of Mexico was recently awarded as a precursor to a one year measurement program.

Our platform-based measurement system in Trinidad, which provides meteorological, wave and current profile data in real-time, continues to collect data nearly flawlessly as it reaches two years of continuous operation. 

The first phase of a project to analyze data collected in ADCP surveys of eddies and the Loop Current data for the joint industry group, CASE-EJIP, was been completed and Phase 2 has just been initiated.  The purpose of this project is to better understand the kinematic structure of highly sheared fronts associated with strong current features and thus improve criteria affecting offshore design and operations.

And last, but far from least, provision of oceanographic support personnel to an oceanographic vessel offshore Brazil in partnership with C&C Technologies has been in full swing for over a year.   Standard sub-surface mooring deployments and service visits have continued through the year.  In addition, a surface buoy has been designed, fabricated and deployed  that receives data acoustically from a taut subsurface current mooring and transmits those data to shore via satellite.

As usual, still hanging in the balance are proposals requiring a large range of capabilities from real time systems, moorings and analyses both domestically and internationally.

PEOPLE ON THE MOVE.

WOODS HOLE GROUP'S CORPORATE ORGANIZATION KEEPS ON GROWING and we would like to announce developments within our corporate organization:

George Hampson, Woods Hole Group's Senior Marine Biologist and mainstay of both Company and Community, has retired.  He will still be consulting on contracts as needed, but he now becomes  Emeritus at Woods Hole Group as well as Woods Hole Oceanographic Institute. Here is an excerpt from his WHOI biography:

"George was born in Holyoke,Massachusetts but in, but if you ask him, he will say with a smile that he is a Cape Codder. His family summered in Pocasset, near a small, marshy creek that provided an “open school” to learn about the water and the critters living in it. When he was a teen, his family moved permanently to Nye’s Neck in North Falmouth.

After schooling at Tabor Academy and an undergraduate degree from Northeastern University, he found work in 1958 assisting WHOI biologist Howard Sanders with an ecology course at the Marine Biological Laboratory. He joined the U.S. Army in 1960, but was back on the streets of Woods Hole within a year, serving as an Army reservist and looking for work. Sanders soon hired him as a research assistant for WHOI.

For 37 years, he worked alongside Sanders and colleagues that included Hovey Clifford, Bruce Tripp, Bob Hessler, Fred Grassle, Rose Petrecca , and John Farrington. He was a jack-of-all-trades—field sampler, lab analyst, diver, naturalist, and biochemist—who contributed to studies of marine invertebrates from the intertidal zone to deep water. He worked extensively with Sanders, Max Blumer, and two generations of scientists exploring the effects of oil spills on the marshes and coastlines of Buzzards Bay. He also worked to find and classify many species of benthic animals, particularly the primitive, throwback crustacean known as the cephalocarid, which was discovered by Sanders. Among many visitors to the Sanders lab, the most famous was probably the emperor of Japan.

George’s interest in the ocean and coast carried over into his home and civic life. He went to his first public hearing in the early 1960s, and he has been actively involved in local government and resource management ever since. He served on the planning board for the Town of Falmouth, as a founding board member for the Coalition for Buzzards Bay, and he now chairs the Falmouth Coastal Pond Management Committee. He was a founding member of the 300 Committee, a non-profit land trust organized in 1985 to preserve Falmouth’s open spaces.

Though he officially “retired” from WHOI eight years ago, George is still hard at work on several coastal programs, including the Massachusetts Estuaries Project, a group that studies water quality in 89 embayments around the state. One of his favorite activities is teaching people of all ages about the coast and coastal waters. “I am just giving something back for all that I have gotten from this community,” he says."

In 2007 George was the recipient of the Falmouth Heritage Award from the Falmouth Historical Society.  The award honored George for "... distinguished leadership in heritage preservation over a period of years. His efforts resulted in a lasting contribution that continues to benefit the town, its residents and its visitors, and has inspired others to value the richness of Falmouth’s past." 

In addition, George continues to be a mainstay of the Massachusetts Estuary Program (MEP) based out of UMASS Dartmouth.  We are certain that he will also continue his long-standing work in teaching science to school-children throughout the area.

To George we offer our congratulations and our deep appreciation for a career full of achievement that has inspired us all.  Please join us in wishing George and Barbara a happy retirement, full of rewards they both so richly deserve.

David R. Walsh, M.S. was named EMPLOYEE OF THE YEAR at the Woods Hole Group Holiday Party this past December 2008.

Congratulations David!!



Matthew F. Shultz, P.E. passed the Professional Engineering exam in October 2008 and is now a licensed engineer.
