Common Strategy

Research vessels and their equipment are one of the most reliable means we have of accessing diverse marine environments to conduct research. The ocean and its inhabitants play a significant role in the changes facing the globe, and developing our understanding of marine ecosystems is therefore more important than ever. Marine research infrastructures are critical for supporting the continued development of marine scientific evidence. Given their importance, a review of the current European fleet and its capabilities was conducted, with information also gathered on fleet management and operation, and on training.This Policy Brief outlines why we need research vessels, explaining the multiple roles they play in supporting marine science and ocean observing. It presents an overview of the current European fleet and its capabilities, including specialized capacity to conduct research in deep-sea and Polar regions. It highlights the importance of transnational access for European researchers within this context. It also briefly outlines the concerns around training for vessel crew, marine technicians and shore-based staff. It then presents the main recommendations of EMB Position Paper 25, which are applicable to the research vessel and marine science communities, national and Euoprean funders and to policy makers. This publication summarises the main messages and recommendations of the recent EMB Position Paper 25 on “Next Generation European Research Vessels: Current Status and Foreseeable Evolution”, which was produced in collaboration with the European Research Vessel Operators (ERVO) community. The Position Paper provided a comprehensive look at the current research vessel fleet in Europe, updating the findings and recommendations of EMB Position Paper 10 from 2007 on “European Ocean Research Fleets - Towards a Common Strategy and Enhanced Use”.

Abstract De Robertis, A., Wilson, C. D., Furnish, S. R., and Dahl, P. H. 2013. Underwater radiated noise measurements of a noise-reduced fisheries research vessel. – ICES Journal of Marine Science, 70: 480–484. Vessel-radiated noise is traditionally measured at naval acoustic ranges, but lower-cost options are desirable for routine monitoring of research vessels. Measurements of a noise-reduced research vessel made at a naval noise range are compared to those made using an experimental mooring equipped with commercially available instrumentation. The measurements from the mooring were precise and within 2.5 dB of those from the noise range at third-octave bands <500 Hz. At higher frequencies, direct comparisons were precluded by an intermittent shaft-related noise present only during the mooring measurements, but previously observed at the navy range. The agreement between the two methods suggests that simplified, field-deployable hydrophone systems can be used to accurately characterize the noise signatures of research vessels.

Dr. William Livingstone Ford played an important role in the development of Canadian marine science after World War II. Trained as a physical chemist, he spent the early part of his scientific career in the United States with Dupont and the Woods Hole Oceanographic Institution. From 1948 to 1965 he held various positions with the Canadian Defence Research Board across the country. The highlight of his long career was serving as the senior manager of the Bedford Institute of Oceanography in Dartmouth, NS from 1965 to 1978. He was a prominent leader in the national marine science community and a member of the Nova Scotian Institute of Science. This article summarizes highlights of his distinguished career as a both a scientist and government manager and his many contributions to Canadian oceanography. He was a well-respected science manager who developed a productive and collegial management style that encouraged different agencies to work together on multidisciplinary programs.

Abstract De Robertis, A., and Wilson, C. D. 2010. Silent ships sometimes do encounter more fish. 2. Concurrent echosounder observations from a free-drifting buoy and vessels. – ICES Journal of Marine Science, 67: 996–1003. The reactions of walleye pollock (Theragra chalcogramma) to the NOAA ships “Miller Freeman” (MF), a conventionally designed research vessel, and the “Oscar Dyson” (OD), a noise-reduced research vessel, were compared near the Shumagin Islands, Alaska. Observations with a buoy-mounted echosounder indicated a stronger decrease in pollock backscatter strength and a greater increase in pollock backscatter depth associated with the passage of the MF than the OD. The pollock began to respond at a distance of ∼270 m from the vessel and were disturbed for several minutes after vessel passage. The reaction to the OD was weak, suggesting that measurements of pollock made by the OD in this environment are not strongly biased by vessel avoidance. Comparison of echosounder observations collected on board each vessel indicated that the MF measured less pollock backscatter, a deeper pollock depth distribution, and weaker single-target echoes than the OD. Together, the results indicate that acoustic measurements from the two vessels are not equivalent because of a reduced avoidance response to the noise-reduced vessel.

Abstract Needle, C. L., and Catarino, R. 2011. Evaluating the effect of real-time closures on cod targeting. – ICES Journal of Marine Science, 68: 1647–1655. Under its Conservation Credits scheme to reduce cod mortality, the Scottish Government has implemented a system of real-time closures (RTCs) since 2008. These are relatively small, temporarily closed areas (50–225 square nautical miles per RTC, closed for 21 d) that are triggered by high cod catches. An important step in evaluating their effectiveness is to determine the response of vessels to RTCs, because the conservation benefit would be reduced if vessels moved to areas of greater cod abundance following closures. Abundance indices from research-vessel surveys and commercial-vessel observer trips are combined to create a time- and space-dependent relative cod-importance index (RCII). Vessel monitoring system data from Scottish vessels fishing during 2008/2009 are used to construct RCII profiles for each vessel, which are then used to determine whether the areas to which vessels move have a higher or a lower RCII, and how far away they move when an RTC is activated. We show that the RCII of the areas moved to tends to be lower than that of the RTC and that vessels travel farther when moving away from a closure than when moving back after reopening. Although not conclusive, this result indicates that RTCs may impact beneficially on cod mortality.

Using Data

Data science is a new academic field that has received much attention in recent years. One reason for this is that our increasingly digitalized society generates more and more data in all areas of our lives and science and we are desperately seeking for solutions to deal with this problem. In this paper, we investigate the academic roots of data science. We are using data of scientists and their citations from Google Scholar, who have an interest in data science, to perform a quantitative analysis of the data science community. Furthermore, for decomposing the data science community into its major defining factors corresponding to the most important research fields, we introduce a statistical regression model that is fully automatic and robust with respect to a subsampling of the data. This statistical model allows us to define the ‘importance’ of a field as its predictive abilities. Overall, our method provides an objective answer to the question ‘What is data science?’.

With the advent of coherent electron sources with cold field emission guns (cFEGs), it has become possible to utilize the coherent interference phenomenon and perform “practical” electron holography. Historically, holography was envisioned to extent the resolution limit by compensating coherent aberrations. Indeed such work has been done with reasonable success in a few laboratories around the world. However, it is the ability of electron holography to map electrical and magnetic fields which has caught considerable attention of materials science community.There has been considerable theoretical work on formation of space charge on surfaces and internal interfaces. In particular, formation and nature of space charge have important implications for the performance of numerous electroceramics which derive their useful properties from electrically active grain boundaries. Bonnell and coworkers, in their elegant STM experiments provided the direct evidence for GB space charge and its sign, while Chiang et al. used the indirect but powerful technique of x-ray microchemical profiling across GBs to infer the nature of space charge.
