virtual laboratories new opportunities for collaborative Water Science
Hydrology and Earth System Sciences, 2014Co-Authors: Serena Ceola, Emanuele Baratti, Rene Capell, Attilio Castellarin, Jim E Freer, Markus Hrachowitz, Berit Arheimer, Yeshewa Hundecha, Gunter Bloschl, Christopher HuttonAbstract:Reproducibility and repeatability of experiments are the fundamental prerequisites that allow researchers to validate results and share hydrological knowledge, experi- ence and expertise in the light of global Water management problems. Virtual laboratories offer new opportunities to en- able these prerequisites since they allow experimenters to share data, tools and pre-defined experimental procedures (i.e. protocols). Here we present the outcomes of a first col- laborative numerical experiment undertaken by five differ- ent international research groups in a virtual laboratory to address the key issues of reproducibility and repeatability. Moving from the definition of accurate and detailed experi- mental protocols, a rainfall-runoff model was independently applied to 15 European catchments by the research groups and model results were collectively examined through a web- based discussion. We found that a detailed modelling proto- col was crucial to ensure the comparability and reproducibil- ity of the proposed experiment across groups. Our results suggest that sharing comprehensive and precise protocols and running the experiments within a controlled environment (e.g. virtual laboratory) is as fundamental as sharing data and tools for ensuring experiment repeatability and reproducibil-

A portable ASV prototype for shallow-Water Science operations
OCEANS 2016 MTS IEEE Monterey, 2016Co-Authors: Samuel Bertram, Drew Azevedo, Greg Del Vecchio, Ben Hopner, Geoffrey Wheat, Christopher Kitts, William KirkwoodAbstract:Autonomous Surface Vessels (ASV) are capable of performing a wide range of tasks given the emergence of state-of-the-art sensors, wireless communications links, autopilots and supervisory control systems. This paper describes prototyping efforts for a new, low-cost, portable ASV specifically developed for transport by helicopter and backpack in the Arctic. A prototype of this new ASV was developed as part of an 8-month undergraduate capstone project at Santa Clara University. The resulting system has a modular aluminum chassis, marine grade thrusters, and an open source autopilot system. The system has undergone initial field testing and has demonstrated the ability to navigate along paths in a region of interest to within 1 meter. This paper reviews the design of the vehicle, illustrates its navigation performance to date, and discusses plans for future work.

A small scale ROV for shallow-Water Science operations
OCEANS 2016 MTS IEEE Monterey, 2016Co-Authors: Killian Poore, Geoffrey Wheat, Christopher Kitts, William KirkwoodAbstract:Remotely Operated Vehicles (ROVs) are a proven tool for performing highly-capable marine operations ranging from Science investigations to industrial applications. While industry-grade ROVs can support an impressive array of functions, they can be very expensive and complex. As such, they are often inappropriate for use in educational programs where functional requirements are limited but low-cost access, simple designs and safe-to-use systems are paramount. Unfortunately, the common breed of educational ROVs developed for pool demonstrations and K-12/university competitions are often not capable enough to support compelling applications in the field. Over the past 15 years, Santa Clara University's Robotic Systems Laboratory has developed and supported field operations of ROVs at both ends of this spectrum. However, there is great interest in defining a vehicle design that sits in the middle of this trade-space, offering a blend of field capability with cost and complexity constraints consistent with a university program. This paper described the definition of such a vehicle class and the design of an initial ROV built with this blend of features in mind. The paper discusses the key characteristics that dictate the design of the vehicle, describes the design of the vehicle, and reviews its current capability as demonstrated in the field. Future enhancements and upgrades to the systems are also presented.

Modular AUV for routine deep Water Science operations
Oceans '02 MTS IEEE, 1Co-Authors: M. Sibenac, William Kirkwood, Robert S. Mcewen, F. Shane, R. Henthorn, D. Gashler, H. ThomasAbstract:The original Odyssey vehicle systems established a style of platform that has proven to be extremely versatile and useful for a variety of scientific missions. The Monterey Bay Aquarium Research Institute (MBARI) has carried forward the Odyssey design, now called Dorado. Dorado is a mid-sized vehicle in comparison to other AUV systems. Dorado vehicles are 0.5334 m (21") diameter, and are designed for deep Water (4500 m) operation. The Dorado design improves upon the original Odyssey versatility by dividing the vehicle up into modular sections. Specific sections can then be built to carry out each type of mission. A Dorado vehicle can then consist of a nose section, one or several mission-specific midbodies, and a tail section. The main vehicle systems for propulsion, control, data handling, navigation, acoustic sub-systems, and most other standard functions are housed in the tail section. This paper introduces the history of the Dorado systems, and what has been accomplished to date. This paper further describes the various architectural concepts and operational results. Future planning is also discussed.

Virtual laboratories: new opportunities for collaborative Water Science
2014Co-Authors: Serena Ceola, Emanuele Baratti, Rene Capell, Attilio Castellarin, Markus Hrachowitz, Berit Arheimer, Gunter Bloschl, J. Freer, D. Han, Yeshewa HundechaAbstract:Abstract. Reproducibility and repeatability of experiments are the fundamental prerequisites that allow researchers to validate results and share hydrological knowledge, experience and expertise in the light of global Water management problems. Virtual laboratories offer new opportunities to enable these prerequisites since they allow experimenters to share data, tools and pre-defined experimental procedures (i.e. protocols). Here we present the outcomes of a first collaborative numerical experiment undertaken by five different international research groups in a virtual laboratory to address the key issues of reproducibility and repeatability. Moving from the definition of accurate and detailed experimental protocols, a rainfall-runoff model was independently applied to 15 European catchments by the research groups and model results were collectively examined through a web-based discussion. We found that a detailed modelling protocol was crucial to ensure the comparability and reproducibility of the proposed experiment across groups. Our results suggest that sharing comprehensive and precise protocols and running the experiments within a controlled environment (e.g. virtual laboratory) is as fundamental as sharing data and tools for ensuring experiment repeatability and reproducibility across the broad scientific community and thus advancing hydrology in a more coherent way.
