CTD Deployments and anti-fouling
James Walton, sales manager of AML Oceanographic (formerly Applied Microsystems Limited) will talk about some interesting CTD deployments in Canada and Kuwait and then go on to discuss UV based anti-fouling techniques.
AML is based near Victoria, Canada and is an innovative manufacturer of Sound Velocity, CTD and environmental sensors, probes and instruments. AML’s success story originated with developing UV protected CTDs for the Smart Oceans project run by Ocean Networks Canada. Their UV biofouling protection technology was developed and tested with the help of the Folger Pinnacle node on the NEPTUNE cabled observatory, and soon after concluding the test there AML supplied 5 CTDs to be deployed on Smart Oceans. They made one or two mistakes along the way, and James will recount the story of the sale, what went wrong, what they did to fix it, and an example of a later sale to another customer where they learned from their previous mistakes.
Mr. Walton has a BSc in Electrical Engineering from the University of Alberta, and lived in Japan for 6 years. James joined the AML sales team in 2011, and is currently sales manager for environmental and science-related projects globally, supporting the regional sales people, agents and resellers.

Mobile and Miniature Mass Spectrometers for Marine and Space Applications (pdf)
In situ mass spectrometry in extreme environments, such as in the deep ocean or outer space, poses significant challenges. Many of these challenges are common, including the requirements for high reliability, autonomous or remote operation, ruggedness to deal with rapidly changing environmental conditions, and restrictions on size, weight, and power. Other engineering concerns are specific to the particular environment, such as extreme pressure differentials between ambient hydrostatic pressure and mass spectrometer vacuum at depth in the ocean, and extreme temperature ranges in deep space.
We have been developing underwater mass spectrometers and have deployed these instruments on a variety of underwater platforms, such as tow sleds, vertical profiling frames, remotely operated vehicles (ROVs), and autonomous underwater vehicles (AUVs). One of the primary targets in recent years has been in situ characterization of underwater natural hydrocarbon seeps and leaks.
More recently, we have begun to design and test a prototype micro-machined ion trap array mass spectrometer aimed at detecting and identifying low-molecular-weight biomarkers, ultimately to be adapted for space missions of astrobiological relevance. We plan to demonstrate that the prototype instrument can detect and characterize water and compounds of prebiotic relevance, such as those on the surface of comets.

ClearSignal Biofouling Protection for Marine Instruments
Hank Lobe, Severn Marine Technologies, LLC
Historically, bio-fouling control has been achieved by exploiting the toxicity of metals, organometals and other similar biocides to marine invertebrates and incorporating them in paint matrixes to form antfouling coatings. This class of coatings and associated methodology is unacceptable for undersea instruments for a variety of reasons which include: optical transparency, changes in density over time, toxicity to personnel and the environment, and degrading efficacy.
Other antifouling techniques that are sometimes used on oceanographic instrumentation such as ablative greases containing various pepper extracts were also evaluated but judged to be unacceptable when evaluated against the performance requirements of long term effectiveness, durability, occupational safety and constant density.
Severn Marine Technologies LLC and its Corporate Partners, Mid Mountain Materials Inc. has developed a newer class of coatings, ClearSignal, that has been designed specifically for oceanographic instrumentation and advanced undersea platforms. The system is presently being used by the US Navy, Port and Harbor facilities, offshore oil and gas interests, instrument providers to the the NSF OOI program and others.
The topic area is particularly timely as the science and commercial industries have in the last several years realized an acute need the technology described. Examples of this are the $400M dollar plus NSF Ocean Observing Initiative, the US Navy Persistent Sensing programs and the commercial seismic oil exploration expanded use of seismic streamers that incorporate sensors which are highly susceptible to the acoustic noise generated from biofouling settlement.
Information will be presented on the specific biofouling protection and performance requirements of a variety of oceanographic instrumentation and platform types. Specific examples and data from a variety of commercial and scientific Glider and oceanographic instrument deployments will be presented in order that the listener can ascertain the full range of biofouling protection possible with state of the art biofouling control solutions. The listeners will be encouraged to describe their particular biofouling issue as related to oceanographic instruments and platforms in order that a solution and performance expectation can be described for that application and instrument.

The Wave Glider: A Wave Powered Autonomous Surface Vehicle for Operational & Predictive Oceanography
Neil Trenaman, Vice President of International Business Development, Liquid Robotics, Inc.
The Wave Glider wave-powered unmanned maritime vehicle (UMV), represents a novel and unique approach to persistent ocean presence. Wave Gliders harvest the abundant energy contained in ocean waves to provide essentially limitless propulsion while two solar panels continuously replenish batteries that are used to power the vehicle’s control electronics, communications systems, and payloads. Wave Glider is a hybrid sea-surface and underwater vehicle in that it is comprised of a submerged “glider” attached via a tether to a surface float.
The Wave Glider is well suited for air-sea surface investigations. With a continuous view of the sky the vehicle makes use of GPS for precise navigation and iridium, or other RF communications, for command and control. The Wave Glider can operate as a vessel, covering long distances in the ocean, or as a station-keeping platform. Test results, to be included in this presentation, will discuss both roles.
In this presentation, we review the design of this platform and present results from the extensive engineering sea trials conducted with prototype and production versions of the vehicle. The vehicle’s performance in a variety of ocean conditions --- varying sea state, wind speed, and surface currents --- is discussed. Differing wind and wave conditions yield varying performance of the Wave Glider. Field experience and analytical results will be presented. While each situation is unique experience indicates the Wave Glider can achieve an average speed of 1.5 knots.
In addition to the basic Wave Glider technology we will focus on the role of currents in the operation of the vehicle and as an application. Liquid Robotics operators have become familiar with a variety of ocean environments including the Pacific Ocean between Hawaii and California and the Gulf of Mexico. Field experience will be discussed. Recent projects have explored the Wave Glider’s ability to enter a “drifter” mode by entering a locked turn. Preliminary assessments of this approach will be presented.
The Wave Glider is also able to carry a water speed sensor for the evaluation of relative velocity through the water. Combined with GPS measurements of velocity relative to the earth the immediate surface current may be derived. An analysis of this technique will be presented. Finally this presentation will discuss the integration of an acoustic Doppler current profiler (ADCP) on the Wave Glider. The technical implementation and preliminary data results will be described.

Determining Battery Capacity with your Laptop
Kevin Hardy, Senior Development Engineer
Scripps: Institute for Geophysics and Planetary Physics, Marine Biology Research Division
Turn your laptop into an advanced battery tester for between $150-$300. You can then easily determine what effect current drain, temperature, or pressure will have on the capacity of your system battery. The CBAIII Pro from West Mountain Radio will be demonstrated. Set-up is easy with a USB cable to the PC, software CD, and battery leads.
Unlike a simple resistive load tester, where current will change with decreasing voltage, the CBA will perform a constant current test on virtually any type or size of battery, any chemistry, with any number of cells up to 55 volts, recording data continuously to your PC. Your results of single battery, or series and parallel stacks may be surprising. The CBAIII has a few quirks, but all and all it's quite useful.
The CBA is capable of test rates of up to 40 amps or 150 watts, whichever is higher. Versions to handle up to 2000 watts are possible. It graphically charts voltage versus amp-hours until a pre-determined cut-off voltage is reached, where you see total amp-hr capacity.
Graphs may be displayed, saved and printed. Multiple graphs of the same battery, or multiple batteries, may be overlaid for comparison. Battery tests may be printed on a color or black & white printer, or saved as a pdf and e-mailed. Test results can be printed on Avery 5160 labels to be affixed to individual batteries to log their test date and performance.
More info on the CBA III is at:
Bonus presentation: Deep water plastic spheres
In any time remaining, moderate-cost injection molded trawl floats will be shown which have the potential for use as instrument housings to 1,400m. Injected molded hemispheres of styrene plastic are thermally fused into a hollow sphere. Some interesting opportunities exist. ABS (Acrylonitrile butadiene styrene) and styrene plastic maybe solvent welded to create ports. All plastic model building techniques apply. Samples will be shown. If anyone is willing to try this, see the speaker afterwards. We'd ask the experimenter to share their results, good or bad, at a later STF meeting.

CONTROS PRESENTS IMPROVED HYDROC™ CO2 SENSOR (pdf)
Stefan Kramer - email@example.com
CONTROS Systems & Solutions GmbH, Kiel, Germany, has recently introduced an upgraded version of the optical based underwater CO2 sensor, “HydroC™”, following extensive proving trials and scientific validation. The CONTROS HydroC™ sensor was evaluated for its easy handling and very positive quality characteristics in the ACT performance statements, which were announced by the organizers some weeks ago (http://www.act-us.info ).
The latest version of the CONTROS HydroC™ sensor includes the external SBE-5T pump with a special designed flow head. Using this pump and its special designed flow head, the CO2 sensors response time has been dropped down to 1 minute, which makes it the fastest on the market and also the response time of the HydroCTM CH4 sensor has been decreased down to 2 min. To achieve this effect several flow heads were designed with the aid of 3D CAD programs, where also flow simulations were done, afterwards the designs were put to test in order to get the actual performance of each design. At the end, the head design with the fastest flow and signal was chosen.

Li-Ion chemistry is ideal for undersea environments. The cells are sealed and do not out-gas and the polymer versions can withstand pressures greater than 10,000 psi. This combination results in a battery that is easier and safer to use and one that does not require heavy, expensive pressure vessels.
Recent advances in electronic control of the Li-Ion battery and new modular design concepts for construction of complex battery systems have resulted in battery systems that are more robust, more flexible, longer lived, easier to charge and maintain, and more safe than their lower density counterparts. These new Li-Ion battery systems can be designed to deliver this energy at high voltages and high currents. Electronic charge control within the battery system allows charging by direct connection to power supplies or constant power sources such as fuel cells and solar panels.
The modular design concept for Li-Ion and Li-Polymer battery systems are presented with an emphasis on construction for undersea applications. Key to the modular battery system design concept is the ability to electronically balance all the cells within the battery system automatically without operator intervention. Two different methods are described that show how electronic balancing of all the cells within the battery system are accomplished. Examples of production battery systems already in service are shown and systems under development are provided.

High Brightness Light Emitting Diodes in Underwater Applications
Kevin Hardy, VP
DeepSea Power & Light
San Diego, CA
Undersea lighting continues to follow the rapid development of Light Emitting Diodes (LEDs) for general commercial illumination. LEDs have made substantial headway in their adaptation to undersea vehicles given to their light generation characteristics, efficiency and durability. In addition to improvements in LED technology, electronic drivers have become simpler and increasingly efficient, providing options to end-users for thermal roll-back, dimming, AC/DC, or variable voltage input with constant current output. DSPL engineers have devised ways to pressure compensate both the LEDs and the driver electronics, successfully testing LED arrays and drivers to 20,000psi. New light system configurations are emerging for diver, manned submersible, and
unmanned vehicle applications.
This presentation will discuss differences with and advantages over gas discharge lamps, advances in High Brightness LED lighting systems, in-house validation testing methods, and suggest where ongoing developments will take us next. Recent at-sea experience by manned and unmanned vehicles will be shown.

Recent Advances in Affordable Ion Trap MS Technology
And Their Applications in Natural Products Characterization
Abstract: 3-D ion traps have been a part of the Liquid Chromatography Mass Spectrometry (LCMS) landscape for over a decade, providing multi-path mass spectrometry experiments (ms/ms or msn) for unknown screening and structure elucidation. Recent advances in ion trap LCMS features including Enhanced Charge Capacity (ECC) which extends the number of ions that can be simultaneously analyzed and electronic control of Atmospheric Pressure Ionization (API), which delivers optimum drying gas during gradient LC separations by controlling the temperature distribution throughout a complete analytical run have resulted in producing an overall increase in sensitivity and a reduction in background interference while lowering the ownership price threshold. These features facilitate the economical analysis of complex and thermally labile compounds, including pharmaceutical, natural products and their associated metabolites. This talk will discuss in detail these new advances and will give examples of this technology applied to the characterization of molecules derived from natural products.

Is Swarm Sensing in the Ocean An Idea Who’s Time Has Come?
Marine Physical Laboratory
Scripps Institution of Oceanography
The understanding of oceanic processes has always been hindered by the difficulty in measuring them. Almost all types of propagating waves are either rapidly attenuated or suffer little and non-specific interaction with the ocean’s interior. The latest generation of ships, moorings, gliders all offer advantages, however, still suffer from significant aliasing. Via the revolution in micro processing technology, power storage and the continuing advancement of low cost sensors the opportunity to launch swarms of small, autonomous, self contained, and communicating vehicles now exists. Such vehicle swarms could sample oceanic processes on space-time scales that were heretofore unobtainable while being transported at lower Reynolds numbers. This permits the measurement of ocean currents while at the same time providing a view from the point of view of small animals that cannot swim faster than these currents. Among the many interesting processes that can be investigated using these ideas are coastal larval transport, the measurement of various features of sub mesoscale eddies, and the evolution of thin oceanic layers of phytoplankton. This talk will describe the speaker’s experiences in developing autonomous platforms for ocean sensing, his vision of the evolution of these systems, and the role that they can play in helping to achieve a better understanding of the dynamics of the ocean’s interior and the processes that occur within.

Eonfusion, Myriax’s Data Fusion Project: Closely coupled visualization, analysis and data fusion tools for 4D environmental data.
Dr Tim Pauly, President, Myriax Inc.,
2877 Historic Decatur Rd. Suite 400, San Diego, Ca 92106
Tim will present some background and an overview to Myriax’s data fusion project, and demonstrate the emerging 4D visualization and data fusion capabilities of the new Eonfusion application.
We aim to enhance the excitement of discovery that visualization brings to data analysis, to provide a suite of tools that makes the interesting absolutely fascinating and the mundane easy, and ultimately to offer ‘inter-ocular traumatic impact’ - understanding that hits you between the eyes.
Eonfusion is a novel new software tool being built by Myriax (formerly SonarData) that is extending the possibilities of data fusion and visualization. With compelling 4‐dimensional visualization and a ground breaking topology and fusion engine, the system is ideal for dealing with complex modelling and spatial temporal analysis. This demonstration will show some of the applications of the new software to environmental data visualization and modelling.
Tim Pauly – PhD, GradDip(Applied Physics), BSc. Tim joined CSIRO Department of Horticulture, South Australia in 1982. He developed innovative computer programs for their genetics laboratory to automate a spectrophotometer for data acquisition and recombinant DNA analysis; and to standardize and analyze electrophoresis gels. In 1987 he commenced consulting, lecturing and contract work as a research associate for the Centre for Marine Science and Technology at Curtin University, Western Australia, participating in a wide range of projects. These included: generated 3-D predictive wave spectra data for the Indian Ocean as input to a novel yacht velocity predication package for the Australian Americas Cup Defense; yacht based deep ocean acoustic bathymetry system used for sea mount detection and satellite ground truthing; and the design and construction of an acoustic data logging and analysis system for the determination of the acoustic target strength of Antarctic krill. Tim then moved to Hobart to lead the marine acoustics stock assessment program within the Antarctic Marine Living Resources Group for the Australian Antarctic Division; and represented the Australian Government at numerous international meetings such as Working Group meetings for the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) and International Whaling Commission (IWC). In 1995 he co-founded SonarData and in 2001 left the Antarctic Division to work full time at SonarData, (now Myriax Software). He has set up and led the data fusion project at Myriax Software Pty. Ltd. in Hobart Australia over the last few years which has culminated in the Eonfusion software application.

Science and Art: Globes of Hope
Cindy Clark - Director of Scripps Communications
Cindy is the contact for a scientific project in the works that needs input from our ocean technology experts.
In a nutshell, a TV producer has conceived a global art installation project with an oceans theme. It consists of launching seven, 40-foot diameter spheres into the world's oceans to bring attention to the oceans. Scripps has been invited to be a science partner with no financial obligation.
We can help validate the science value of this art/environment project. Tony Haymet is very interested in Scripps's involvement and suggests placing GPS on these spheres so they could be recoverable if lost. This is an open discussion about what scientific instrumentation is feasible and could be valuable to add to these spheres; how feasible this entire project may be; and who may be interested in taking this a step further for Scripps.

The New Marine Science Development Center
The SIO Marine Science Development Center (MSDC) has recently moved to new quarters in the SIO Service Yard. Their new space is much larger and their capabilities have been augmented with new equipment. Come hear about what they offer and see examples of completed work. The discussion will include tips on submitting drawings for fabrication.
MSDC specializes in the design, development, and fabrication of oceanographic and space equipment that range in scale from minute laser components to large-scale integrated systems. They are capable of quantitative instrument and assembly production, or custom engineering design and fabrication to suit any need. They have been serving the scientific community here at SIO, UCSD, and various other institutions, as well as the private sector, since 1945.
MSDC has continued to meet the demands of modern science and engineering technologies by adding five CNC machines to it's facilities. Computer Numerically Controlled machining (CNC Machining) contain machine tools that are called machining centers, turning centers, Wire EDM (Electrical Discharge Machining), screw machines, etc. CNC machines are programmed by converting part geometry in Cartesian coordinates (X,Y, Z) and formatting those coordinates into a programming language such that the CNC controller can interpret them by moving the axes of the machine tool to automatically remove the required material from the work piece to form the finished machined component. CNC machining produces parts in a very consistent manner and is ideal for large quantity part runs and parts with complex geometry.
MSDC automates the programming of CNC machines by utilizing CAD\CAM (Computer Aided Design \ Computer Aided Manufacturing) software, so that designs on paper can be transformed in digital geometric drawings. The part drawing is transferred from SolidWorks to FeatureCam, allowing the machinist to apply and visualize various machining strategies in a virtual on-screen environment. Once the machinist is satisfied with a particular machining strategy, FeatureCam will output the CNC code, commonly referred to as G-code post processed, which is now ready to load into the controller of the machine tool that will be used to actually perform the machining operations.

Pressure Tolerant Electronics - Design Principles and Applications
Corey Jaskolski, President, Hydro Technologies, (Windsor, CO)
Pressure tolerant electronics eliminate the need for pressure vessels in underwater applications. As research and defense applications push for systems that can go deeper in the ocean for longer periods of time, designing with pressure tolerant electronics can result in significant costs savings and increases in system reliability. There are several simple design, pressure compensation, and testing techniques that, if followed will result in a pressure tolerant system whether applied to a new design or to the modification of existing equipment. Several examples (both good and bad) taken from real world industry, academia, and film applications will be examined.
Corey Jaskolski, President, Hydro Technologies, graduated from MIT with a MS EE-CS. While at MIT he also worked at unmanned underwater vehicle (UUV) developer Bluefin Robotics, where he led the early development of the first pressure tolerant Lithium Polymer battery packs. In 2001, Jaskolski spent several weeks aboard the Russian science vessel, the Academic Keldysh, in support of James Cameron's documentary filming of the Titanic. During this expedition, Jaskolski got the opportunity to descend 12,500 feet to the wreck of the Titanic to support robotic operations. Jaskolski is featured in the film "Ghosts of the Abyss", a Walt Disney picture that covers this expedition.
