“…However, there are still substantial questions about the relatively thin, stably stratified upper ocean boundary layer, mostly due to a lack of necessary observations. New instrument platforms and techniques provide novel ways to observe and investigate the upper ocean, and more specifically the relatively shallow stable layers (Daniel et al, 2011;Peterson and Fer, 2014). This dissertation explores those layers.…”

“…In addition to the central mooring and to obtain better spatial coverage of the SPURS-I study area, Liquid Robotics Wave Gliders (Daniel et al, 2011) were deployed during the field campaign, and remained in the water for a year-long mission (other than a few days during the midterm cruise for servicing). Three Wave Gliders moved around a 1 ∘ x 1 ∘ box near the central mooring in repeating paths to provide good temporal and spatial coverage.…”

The global movement of people and goods has increased the risk of biosecurity threats and their potential to incur large economic, social, and environmental costs. Conventional manual biosecurity surveillance methods are limited by their scalability in space and time. This article focuses on autonomous surveillance systems, comprising sensor networks, robots, and intelligent algorithms, and their applicability to biosecurity threats. We discuss the spatial and temporal attributes of autonomous surveillance technologies and map them to three broad categories of biosecurity threat: (i) vector-borne diseases; (ii) plant pests; and (iii) aquatic pests. Our discussion reveals a broad range of opportunities to serve biosecurity needs through autonomous surveillance.

Wave glider is the first unmanned autonomous marine robot to use only the ocean's endless supply of wave energy for propulsion. Wave glider comprises fin system, tether and float which harvest all of its energy from waves and sun to produce forward thrust. As a consequence of the lack of design information and data for the wave glider, the main aim of the study is using computational fluid dynamics (CFD) to present a method to predict calm water resistance for the floating hull through calculations of 3 different hull forms using the same mesh generation under the same conditions. Calculations are carried out using 3 different mesh sizes for Froude number in the range of 0.10 to 0.40 and compared for accuracy of the solution parameters. Wigley parabolic hull, high speed round bilge form (NPL) and Series 60 have been comparatively investigated in order to estimate the hydrodynamics performance of the hull. The linear seakeeping analysis, coupled heave and pitch motions, roll motion, in irregular waves, with one parameter Bretschneider and JONSWAP spectra. Numerical computations have been performed for motion response predictions of the three hulls which cover wave angles from 0˚ to 180˚ at 45˚ intervals for six different forward speeds from 0 to 4.304 knots using Maxsurf Motion software.The close agreement between the numerical predictions shows the importance of CFD applications in estimating the hydrodynamics performance to design the floating hull and the numerical method is useful in glider design. The fine grid is fit to the calculation and shows the most appropriate results because convergent results are obtained as the mesh size decrease so the fine grid is the one which will be applied for the other hulls. Also it can be observed that the added resistance and the RAOs for NPL hull are less than the other hulls. Therefore from the comparisons, the NPL hull is the optimum hull compared to the other hulls from the resistance and seakeeping point of view.How to cite this paper: Ahmed, A.M.E.
