FALMOUTH SCIENTIFIC ANNOUNCES A NEW LOW FREQUENCY ADDITION TO THE BUBBLE GUNTM FAMILY OF SEISMIC SYSTEMS
Cataumet, MA, USA – March 12, 2014 – Falmouth Scientific, Inc. (FSI), a global leader in oceanographic instrumentation and marine systems integration, is very excited to present the HMS-620LF Low Frequency Bubble GunTM Seismic System at Oceanology International 2014.
FSI’s Bubble Gun Systems are perfect for small boat shallow water geophysical surveys. Bubble Gun systems utilize a contained air volume to generate narrow band, low frequency acoustic signals. The data collected with HMS-620 systems rivals that of much larger, heavier, and more expensive air-gun, boomer, and sparker systems without the need for large power sources or air compressors. This proven technology provides superior signal penetration through coarse sand, gravel tills, and other difficult to penetrate sediments.
With some new technology developments and increases in the physical dimensions of the acoustic transducer FSI can now offer a much lower bandwidth system that gives even deeper signal penetration. Previous Bubble Gun systems demonstrated frequency characteristics in the low-hundreds of hertz, but the new HMS-620LF shifts the spectrum downward such that it produces substantial energy components below 100 hertz. And the new system only needs a small 2 KWatt generator as its power source.
FSI’s HMS-620LF seismic source vehicle is on display in Booth A150 at Oceanology International 2014 being held this week in London, UK. Please stop by for more information and an in-air demonstration of this new, powerful, sub-bottom profiling tool.

Data collected with the HMS-620 rivals that of much larger, heavier, and more expensive air-gun, boomer, and sparker systems, and its small size makes it easily deployable without the need for heavy machinery, winches, or cranes.
Bubble Gun systems utilize a 15 cubic inch air volume to generate narrow band, low frequency acoustic signals. This proven technology provides superior signal penetration through coarse sand, gravel tills, and other difficult to penetrate sediments.
New Dual Source System Available
By adding a second transmit channel to the existing transceiver enclosure, and by synchronizing the two signal generators, FSI has realized significantly higher energy output, which results in much deeper signal penetration. The two Bubble Gun source transducers can be mounted together on one tow vehicle, or can be configured as two separate single-source vehicles.
New Battery Powered 24 VDC Option
All of FSI’s Bubble Gun systems can be fitted with a 24 VDC power option which allows them to be powered by lead-acid marine batteries. This means that you can perform shallow water seismic surveys without the need for a generator or ship’s power. Two deep-cycle marine batteries will allow over ten hours of survey time on a single charge. No generator noise, no fuel, no exhaust, all with no degradation of the data.
Falmouth Scientific offers other sensor based products such as current, wave, and tide meters; solutions for drilling & vortex induced vibration monitoring; portable sidescan sonar imaging; and other acoustics-based underwater instrumentation.

Sept 2010 - Law enforcement officials rely on FSI’s HMS-1400 Portable Side Scan to speed search and recovery efforts
The HMS1400 side-scan sonar, a product released in early 2010 by Falmouth Scientific Inc., was utilized in an effort to find and recover the body of a drowning victim. The California sheriff’s office in charge of the case had spent 72 days and countless resources for the search before using the sonar, which enabled officials to locate the body in only one hour.
The sonar’s role in this recovery highlights the benefits of its use: small size, usability, and effectiveness even in deep water. The equipment’s powerful software, comparable to software found in more expensive systems, enables swift and accurate target identification through high resolution, real-time side-scan images.
The HMS1400 side-scan sonar offers the advanced technology of larger, more costly systems in a portable and affordable package.
Falmouth Scientific has put together a solution utilizing our standard 2D-ACM Current Meter along with telemetry capabilities and a solar powered charging system. These systems were deployed on buoys in the Commonwealth of the Northern Mariana Islands (CNMI), which is located in the Pacific Ocean due east of the Philippines.
CNMI personnel are now able to download system data from various spots on the island via a mobile receiver unit mounted in their vehicle.
The program is being funded through the CNMI Division of Fish and Wildlife sport fishing restoration program. Through research, monitoring, regulation, enforcement, planning, and management, the Division seeks to ensure the long-term survival and sustainability of the Commonwealth of the Northern Mariana Island's natural resources for generations to come.
March 2010-Falmouth Scientific's New Portable Side Scan Sonar Helps Local Harbormaster in Search and Recovery Effort
FSI and its Hegg Marine Solutions (HMS) Division announced today that the company's new HMS-1400 Side Scan Sonar System helped the Town of Falmouth, Massachusetts, locate a vehicle that had been driven off a local pier into the town harbor. Earlier attempts to locate the car using other techniques had been unsuccessful. John Baker, President of FSI, deployed the HMS-1400 Side Scan Sonar System off the side of the Harbormaster's boat. The sonar system quickly identified a possible target object, which showed up as a large image on the system's deck-based computer screen.Specialized software supplied by Oceanic Imaging Consultants (OIC) of Honolulu, Hawaii, helped identify the object as a likely target. Divers from the Falmouth Fire Rescue department later confirmed that the target was the missing car, which was recovered later that afternoon.
The HMS-1400 Side Scan Sonar System identifies features on the seabed by sending sound pulses into the water and processing the signals that return to the unit after being reflected off the seabed. the time required for the pulse to return to the unit, as well as the strength of the returned signal, can be used to identify features that stand out from the surrounding seabed material.
According to John Baker, "This was an ideal use of the HMS-1400 Side Scan Sonar System, which was designed as a highly portable system to be deployed from small vessels for search and recovery operations, harbor security and inspection surveys, and rapid environmental assessment surveys. We are proud to have been invited to demonstrate the effectiveness of the technology on a project to help the local community."

November 2009-FSI Awarded Contract by SPAWAR
FSI announced that it has been awarded a contract modification by Space and Naval Warfare Systems Center Pacific (SPAWAR) of San Diego for additional effort on an un-tethered, autonomous station-keeping Gateway Buoy (“Gatekeeper”). The Gatekeeper communications buoy is designed to provide persistent communications from subsurface acoustic modems to over-the-horizon assets via RF and satellite telemetry. The contract is an extension of an SBIR Phase II award to FSI in 2006 for development of a prototype autonomous Gatekeeper buoy that harvests energy from the surrounding environment to provide power for sensors, communications, and propulsion systems for maintaining a user-settable watch circle over an extended period. This contract and a related modification bring the total funding for the SBIR Phase II project to over $1.3M.
Under Phase I and Phase II of the SBIR project, FSI and its partners, Vehicle Control Technologies (VCT) of Reston, VA, Autonomous Undersea Systems Institute (AUSI) of Lee, NH, and Mil3 of Cary, NC, designed and built a prototype “Gatekeeper”--a spar-type buoy with a hydrodynamic body, thruster, and mission software that allows it to maintain the watch circle or transit to a new location in response to remote commands in currents up to 3 knots. The buoy also incorporates an innovative energy-harvesting Sea Water Activated Power System (SWAPS™) developed by Mil3. The self-regulating SWAPS assembly uses a magnesium alloy to generate hydrogen when in contact with sea water to energize fuel cells and allows for extended station-keeping deployments at an energy density, cost, and size significantly better than lithium ion batteries. The contract modification provides for system improvements and demonstration of the Gatekeeper Buoy station-keeping performance, communications reliability, and endurance in sea states of 2 to 3 for a two-week period. The endurance test is scheduled for Spring 2010.
September 2009-FSI Posts Instructional Videos On-Line
FSI announced that it has made several instructional videos available to aid customers in configuration and deployment of its 2D-ACM current meters.

Ocean conductivity, temperature, and depth measurements provided by the sensor are also used to calculate sound velocity, salinity, and density for use in weapons targeting and submarine buoyancy determination. FSI has supplied over 150 DT-705 CTD sensors to the Navy under previous contracts. Sensors supplied under the new contract will be used to instrument Los Angeles Class submarines as well as the newer Virginia Class submarines.
FSI DT-705 CTD sensors incorporate a patented NXIC (non-external inductive conductivity) sensor design, which is not affected by proximity of external objects around the sensor. This represents an advance over earlier inductive conductivity sensors, whose conductivity readings could be affected by nearby objects. The NXIC sensor also provides robust operation and highly stable readings. The DT-705 CTD sensor is a shock-hardened design which survived extensive shock tests required for rating as Class A Naval equipment meeting Critical Item Product Specification and environmental requirements.
