Back from Cleopatra’s Palace

Nov 09, 2011

Archeological diver and Aqua Survey employee Eric Wartenweiler Smith recently returned from an expedition in Egypt diving on Cleopatra’s sunken palace as part of renowned underwater archeologist Franck Goddio’s dive team.  Read on to find out his thoughts on:

-Life in post-revolution Egypt

-Tantalizing news on what still waits to be found in the murky depths of Aboukir Bay

-The future of underwater survey technology

Aqua Survey would like to welcome Aqua Survey employee and archeological diver Eric Wartenweiler Smith back from his annual trip to Egypt. 

Each year, Smith participates as a member of renowned archeologist Franck Goddio’s dive team. Goddio is responsible for the discovery of Cleopatra’s sunken palace as well as Napoleon Bonaparte’s flagship. Smith has participated in Goddio’s expeditions since 1996.

No stranger to Egypt, Smith wasn’t sure what to expect in returning for the first time to the country post-revolution. “Besides hearing the firsthand accounts of the revolution from my Egyptian friends, and witnessing many demonstrations and marches in the streets as the process of forming a new government unfolds, I was also particularly impressed by the attitude of the people I met in the street; there was a palpable air of national pride and friendliness, and a real sense of energy and purpose in the young people.”

When asked whether this year’s expedition had any interesting finds, Smith smiled and replied, “While I can’t give specific details, I can say that we’ve found some very exciting new discoveries this year. Franck has said before that we have only found 1% of the artifacts out there and I believe it. I’m excited by the ramifications of what these new discoveries will reveal about ancient Egyptian culture.”

Smith has seen a lot of changes in the field of underwater archeology during the past fifteen years. One of the biggest changes he’s observed is in the survey technology used. “The technology that we’re using now has revolutionized what we’re capable of. The tools we were using just a few years ago seem archaic in comparison. It’s interesting to note that the tools that are revolutionizing underwater archeological work are the very same ones that Aqua Survey uses on a daily basis. It’s a very exciting time to be involved in underwater survey work of any kind.”

Although Egypt, its history and its people hold a certain appeal to Smith, he’s happy to be home and looks forward to getting back in the field with Aqua Survey.

Iconic New York Landmark Keeps Up with the Times

Nov 03, 2011

Due to the renovation of the Panama Canal, the Bayonne Bridge is about to receive a similarly impressive upgrade.

Read on to find out more about the construction of this fascinating bridge and its currently proposed upgrade.

Plus: What services is Aqua Survey providing to support harbor expansion?

Last week Peter Zantal, a general manager at the Port Authority of New York and New Jersey announced that the raising of the Bayonne Bridge by 60 feet would be completed by 2016. Post-renovation, vessels will have 215 feet of clearance under the bridge, allowing the newer, larger Post-Panamax size vessels through. 

A modern engineering feat of its day, the Bayonne Bridge has made it possible for commuters to drive easily from Staten Island, New York and Bayonne, New Jersey across the Kill van Kull since 1931. It’s been a pivotal part of expansion and transportation in the area and its intricate work and astute design has enabled it to last for nearly 80 years.

Created through collaboration between master bridge-builder Othmar Ammann and famed architect Cass Gilbert, the bridge has the distinction of being the fourth-longest steel arch bridge in the world. It was designated a National Historic Civil Engineering Landmark in 1985 by the American Society of Civil Engineers.

The Swiss-born Ammann designed seven of the twelve bridges which connect New York City to its surrounding areas. Ammann became known for creating bridges that were not only cost-effective and durable but also beautiful, which made him quite sought after during the Depression era.

Ammann chose the design of the bridge, a steel arch, over other bridge types as it was cheaper and would accommodate an addition in the future of rapid transit tracks. Soaring 266 feet over the Kill van Kull the bridge is 8,640 feet long. 

After three years of construction, the Bayonne Bridge was completed on November 15, 1931 and cost nearly $13 million. At the time of its completion, it was the longest steel arch bridge in the world. 

A Continued Tradition of Innovation

In a similar innovative spirit to Ammann’s work, the Port Authority has devised a plan for the renovations which will allow the bridge to remain open to motor vehicle traffic during the entire project. The Bayonne Bridge supports thousands of vehicles per day, in fact as of 2003, it was found that more than 20,000 vehicles per day cross between Staten Island and Bayonne. In order to allow this traffic to continue unobstructed a new platform will be constructed above the current one while traffic continues below. When the new platform is complete, the old one will be demolished, thus giving the bridge its new clearance height.

The Port of New York and New Jersey is the largest on the east coast. In 2010, over 32 million metric tons of goods worth more than $175 billion came through the harbor.

The More Things Change, The More They Stay The Same

Renovating New York Harbor is nothing new and has in fact been underway for many years in order to accommodate bigger and bigger vessels.  Aqua Survey has been there in one way or another for decades to support this ongoing expansion, particularly to our clients in the dredging industry who we routinely provide services to ranging from hydrographic surveys and sediment sampling to laboratory analyses and much more.

You may have noticed the USS Chester in the graphic above. It’s the same ship which was pictured traveling through the Panama Canal in August’s email about the reengineering of the Panama Canal.  Aqua Survey President Ken Hayes’s father served on the Chester during World War II.  He was only 17 when he enlisted in the Navy.

Bombs, Elephants and Puerto Rico

Oct 28, 2011

Traveling everywhere from gold mines in Laos to military testing grounds near Puerto Rico, and having used just about every conceivable form of transportation from airplane to elephant to do it, it’s been a busy month for Aqua Survey founder Ken Hayes.  Read on to find out more.


Did you ever live through a month that no amount of imagination could have ever envisioned? 

I am in that month right now.  I have traveled to dozens of countries for business and pleasure in the past. This month I traveled to the remote jungles of Laos to demonstrate some electromagnetic metal detection equipment we designed to meet some pretty demanding unexploded ordnance (UXO or bombs) detection specifications.  The bombs are Vietnam vintage and now buried in the jungle’s metal-rich soil.  The soil is magnetic and conductive and has foiled effective use of other UXO detection technologies in the past. The bombs continue to kill or maim villagers on a daily basis.  Our analog down-hole probe and our digital survey equipment tested well.  That is just part of the story.

Philadelphia to Toronto to Shanghai to Kunming (China) to Bangkok to Ubonratchthani (Thailand) and finally to Sepon from Savannkhet (Laos) by chopper to a remote mining camp in the jungle.  A low altitude chopper flight is an amazing way to take in an incredibly dense jungle sprinkled with a few dozen isolated rice paddy villages. 

About 30 miles outside of Sepon is a gold and copper pit mining operation that the Ho Chi Minh Trail runs right through. Forty years ago we tried to bomb this Vietcong supply route into oblivion.  The area now is strewn with thousands, if not millions, of unexploded bombs.  The mining camp has taken the admirable initiative to train the villagers to use modern detectors to locate and then dispose of the bombs.  The Vietcong also strung trip-wire booby-traps.  What a mess.  To date about 80,000 munitions have been safely removed.  The new equipment we left behind will allow the field teams to detect more deeply buried bombs thus greatly increasing safety, efficiency and effectiveness. 

When I left New Jersey I already knew our equipment would work unless some unknown phenomenon would mug us.  There would be a lot of firsts for me on this trip:

China, Thailand, Laos and Japan
Living in a shipping container
Being in a jungle with wild elephants
Working in a communist country
Walking in areas with cobras and UXO
Experiencing the spiritual center of Laos, Luang Prabang

My mom was a little concerned her 58-year-old son might not be as safe in the jungles of Laos as he would be in Flemington, New Jersey.  Mom...not even one mosquito bite...relax.  Last week Bill Rottner and I did a site visit to Vieques Island, Puerto Rico in advance of upcoming UXO survey tasks.  The place is covered with diabolical plants.  After the work portion of our trip was over, Bill and I decided to grab our snorkel gear and head to the public beach where I promptly stepped on a sandbur plant.  My foot still hurts.  The moral of this story is to pay attention to the really little things, because they are the ones most likely to cause you pain.

Our goal as a company has been the same since 1975: To leave this watery-blue planet in a better shape than we found it.  We pride ourselves in finding a way to get both big and small projects done safely and professionally.

Glacier Dwarfs Skyscrapers: Icy Past Revealed

Aug 25, 2011

Notes from the Field: Ancient Oysters

“Recently we were collecting sediment cores in New York in support of a harbor deepening project. The goal was simple, penetrate deeply until the glacial till is reached. This was a reasonable goal for one of our heavy-duty vibracoring systems. When the sample was retrieved and split open we discovered a strata of oyster shells from an ancient bed that most likely dates back to the Pleistocene era (1.8 million to 10,000 years ago).”

-Don Nazario, Senior Environmental Scientist, Aqua Survey, Inc.

The shell layer which Don found last week is just one reminder of the rich geological and biological history of New York City and its surrounding waterways. The region and harbor owes much of its current configuration to the last ice age when the Laurentide ice sheet advanced and retreated over a period of 60,000 years, reaching its last peak 22,000 years ago.  New York City marked the southernmost extension of the ice sheet, which covered hundreds of thousands of square miles in what are now Canada and the northern United States. Ten thousand years ago global warming accelerated and the region went through drastic changes.  Spruce and tundra were quickly replaced by pine forests and the mammoths and mastodons which once thrived in the region died out.  These transformations are thought to possibly have happened within the lifespan of a human being.  It’s intriguing to imagine how the Paleo-Indians survived such rapid changes.

At its tallest the Laurentide ice sheet covered New York City with a thousand feet of ice.  If New York City was to be covered in that much ice today, only a handful of buildings would poke through, the most prominent being the Empire State Building.

NJ Firm Uses High-Tech Toys in Search for Murder Case Evidence

Aug 05, 2011

Eric Wartenweiler Smith

This past week, Flemington-based Aqua Survey participated in a forensic investigation that is looking for new evidence in a murder case that dates back to the mid-1970’s. On November 13th 1974, six members of the DeFeo family were found shot to death in their Amityville, Long Island, New York home.  The eldest son Butch DeFeo was tried and convicted for the murders.  The aftermath of the shootings served as the inspiration for the 1979 film, The Amityville Horror

Aqua Survey was contracted by filmmaker Ryan Katzenbach to use its proprietary electromagnetic (EM) survey technology to look for a specific piece of evidence which is thought to have been discarded in the nearby Amityville Canal.  Katzenbach is currently producing a documentary entitled Shattered Hopes which will examine the DeFeo murder case with a strong focus on the family and the events leading up to the murders. 

A specially designed EM metal detection device, designed by Aqua Survey, was maneuvered by divers over an area roughly a half acre in size.  Aqua Survey originally developed the technology to detect underwater unexploded ordnance (bombs) and treasure.
Aqua Survey president Ken Hayes said, “While unable to disclose what exactly we’re looking for, I can say that it’s a metallic object weighing in at roughly three pounds.  If it’s there, our team will find it.”

Aqua Survey’s Manager of Marine Operations, Mark Padover led the survey which concluded this past Thursday.  “Over 100 possible targets were identified in the survey area. It’s a heavily developed waterway so there’s bound to be a lot of metallic debris,” stated Padover.  “The next step will be to have divers examine each of these pinpointed anomalies to determine if any of them are in fact the sought after evidence.”

Accompanying Padover was Aqua Survey’s Senior Archeological Diver, Eric Wartenweiler Smith.  Smith is a veteran member of world renowned archeologist Franck Goddio’s dive team.  With Aqua Survey’s support Smith accompanies Goddio, who discovered Cleopatra’s sunken palace off the coast of Alexandria, Egypt, on his yearly expedition to continue excavation of the palace as well as search for new historical sites.

Smith commented on the EM equipment, “Aqua Survey’s new technology opens up a lot of exciting opportunities for undersea discovery. Working with these new tools has me switching from searching for historic shipwrecks, bombs, torpedoes, and crime evidence on a weekly basis. I can’t wait to see what we find next!” In regards to the Amityville project Smith remarked, “I’m looking forward to seeing the results of the finished dive-out. If we find what we’re looking for, it could have drastic ramifications for the verdict of this notorious murder case.”

Later this month Padover will be travelling to Walker Lake, Nevada to lead an Aqua Survey team of scientists.  Smith is also headed to Nevada to assist Padover and then to Egypt to resume his work with Goddio.  For the Nevada project, they will be putting the same EM coil technology to use for its original purpose of finding underwater bombs as well as using a variety of other advanced remote sensing geophysical tools, such as transverse gradient magnetometry, side scan sonar and bathymetry.  Over 50 square miles in size, Walker Lake is adjacent to the Hawthorne Army Depot, one of the largest ammunition storage depots of its kind in the world. 

Aqua Survey, founded in 1975 by Hayes, characterizes sediments and shorelines by geophysical survey, sampling, contaminant studies and archeological investigations.  They pinpoint bombs/munitions, locate lost treasure and weapons, assess environmental toxicity and guide marine archeologists worldwide.  Aqua Survey is headquartered in Flemington, NJ.

“Whether we are locating bombs, ship wrecks, missing cargo, forensic evidence or profiling contaminants in water bodies, work is always an adventure,” said Hayes.  Next month Hayes heads to Southeast Asia to demonstrate a new Aqua Survey tool that can detect 500 pound Viet Nam War-era bombs that are deeply buried in the Laotian jungle.

Aqua Survey Unveils Dredger’s Smart Pipe

Jun 08, 2011

WEDA 2011 Dredger's Smart Pipe

Earlier this week Aqua Survey unveiled their latest innovation at the Western Dredging Association’s 31st conference in Nashville, Tennessee. 

Beach replenishment projects face costly setbacks when munitions are dredged ashore.  Providing a simple solution to an expensive problem, the Dredger’s Smart Pipe will alert its operator when metallic objects are traveling through their dredge’s discharge pipeline.  The system will detect munitions, bomb fuses and other metallic objects. 

Aqua Survey will provide technician training.  Orders for the Dredger’s Smart Pipe are being accepted for late Fall 2011 deliveries.

Dr. Doi to Present at Third International Dialogue on Underwater Munitions

Apr 12, 2011

Environmental Risks of UXO/MEC
Contaminants in Sediment Addressed
by Laboratory Toxicity Testing

Jon Doi, Ph.D., Aqua Survey, Inc.

The primary focus of the detection and removal of underwater munitions has been for the acute effects on humans, i.e., bombs exploding.  However, the greater concern may be on the environmental effects of bomb constituents (propellants and explosives) leaking from bombs for considerable lengths of time. This talk will cover a number of topics on the surveying, sampling and laboratory toxicity testing of UXO/MEC in sediments. There will be a brief discussion on the use of various EM survey devices for UXO/MEC detection and on the sampling techniques used for UXO/MEC-contaminated sediments.  The main part of the talk will be on how our laboratory deals with these types of sediments in the laboratory and what tests are useful. Before the sediment is opened for homogenizing and compositing, it is scanned for possible UXO/MECs. The choice of the type of toxicity test to perform (acute, chronic, freshwater, marine or bioaccumulation), the organism chosen, the conditions of the toxicity test are all important decisions to be made in order to determine whether the sediment is likely to have an impact on the benthic community at the UXO/MEC contaminated site. The identification of bomb constituents and possible toxicity associated with these contaminants will be discussed.
