58 st / August 2017 has awarded its Laurie Prandolini Re- search Fellowship of $14,000 AUD to Fletcher Thompson, who holds a B.Eng. degree in naval architecture and is a Ph.D. candidate at the Australian Maritime College of the University of Tasmania. This fellowship will support Thompson's Ph.D. research project, Project FOX (Fleet Operations and eXpeditions), which aims to establish distributed intelligence into an autono- mous marine vehicle fleet to exhibit collaborative behaviors. Fletcher will be able to obtain ad- ditional equipment for these vehicles and extend the scope of Project FOX. These resources, such as embedded high-performance 3D image process- ing systems, laser-scanning modules and high-resolution mono and stereo camera units, will advance navigation and environmental sensing abilities of the fleet to a globally competitive level. Sampling to Understand Chukchi Biological Processes Biological processes in the upper ocean are complex, and understand- ing them requires measurements of multiple biological and physical prop- erties across a wide range of temporal and spatial scales. In the summertime, the Chukchi Sea is a two-layer sys- tem: warm, fresh meltwater formed by ice melting at the surface overlies cold, salty winter water formed during freeze-up. At the interface between these two layers, temperature and practical salin- ity can change as much as 5ยบ C and 3 PSU over 2 m. Resolving these thin layers requires fast-sampling, high-res- olution instrumentation. A Sea-Bird SBE 49 FastCAT CTD and ECO Puck (chlorophyll-a, CDOM and turbidity) were integrated onto a towed vehicle, providing high-resolution physical and biological maps of the upper ocean in the Chukchi Sea. These instruments were chosen for their high sampling frequency, compact size and ability to transit the data back in real time, enabling adaptive sampling and the resolution of thin and patchy bio- logical and physical properties. Harbor Branch Offers Hands-On Training for Graduate Program Florida Atlantic University is now providing an unprecedented oppor- tunity for graduate students to earn a master's degree while working along- side leading scientists and engineers at FAU's Harbor Branch Oceano- graphic Institute and the Charles E. Schmidt College of Science. The newly launched marine science and ocean- ography graduate degree program is for students interested in coastal and oceanographic science. By incorpo- rating the research faculty at Harbor Branch, the program provides a hands- on academic experience. MacArtney Supplies Multibeam Solution for Harbor Surveys Located on the western border be- tween Basque Country and Gascony, the harbor of Bayonne belongs to the region Nouvelle-Aquitaine. Harbor depth data must be provided to the various harbor operators. MacArtney France has supplied the multibeam solution for a bathymetric vessel to conduct depth surveys. The solution includes a Kongsberg Mari- time EM 2040P shallow-water multi- beam echosounder, a Valeport miniS- VS sound velocity sensor, an iXBlue Hydrins INS, and a Trimble SPS 855 GNSS modular receiver.
