EU/U.S. Roadmap to measuring the results of investments in science: the Bellagio Statement: a report following the “EU/US Science of Science Policy” Rockefeller Foundation Bellagio Center Workshop, 27 June – 30 June 2011

Public and private investments in science and technology (S&T) have significantly increased over the past decades in Europe and the United States. The results have been transformative – ushering in the telecommunications and internet revolutions; providing better access to food, water, and shelter; improving health care; combating environmental degradation and climate change; and helping to inform policies to promote social and economic security. It is essential that these investments continue to create value for the public. Indeed, national governments are increasingly asking complex and probing questions regarding the effects of their investments; they want transparency and accountability for the spending of taxpayers’ money; and they want their decisions regarding investments in science to be informed by data-driven analyses. Now more than ever before, the science community must explain and justify the spending on publicly-funded research. While it is clear that research pays off in general, there is great skepticism about both the marginal value of spending, and the chosen investment targets. There is a clear requirement to ensure greater effectiveness and efficiency in the use of public research funding; reduce the reporting burden on scientists; and to exploit the enormous analytical power generated by advances in information technology. Experts from the European Union and the United States met at the Rockefeller Foundation in Bellagio, Italy, to examine these issues. The task at hand should not be underestimated. Although the potential return from this work is enormous, the scale of the challenge of developing these new ideas into workable solutions for policy makers is also very significant. Despite the major strides already made in the U.S. through the National Science Foundation’s Science of Science and Innovation Policy (SciSIP) program and the interagency STAR METRICS program, a shared approach with other nations would certainly both accelerate progress and implementation. The purpose of the Bellagio conference was to explore the formation of a mutually beneficial multi-national collaboration in documenting the results of investments in science. The group believes science today is a global activity. Scientists and engineers collaborate across borders, move across borders and the benefits of their research know no borders. Expansion beyond current measurement systems could both broaden and deepen participation in science

Geotectonic setting of hydrothermal activity on the summit of Lucky Strike Seamount (37,17'N, Mid-Atlantic Ridge)

We have investigated the relations between volcanic, tectonic, and hydrothermal activity on Lucky Strike Seamount (37°17′N, Mid-Atlantic Ridge) using a nested survey strategy involving collection of data from different deep-sea mapping systems. The highly tectonized seamount summit consists of three volcanic cones surrounding a relatively flat depression with a young lava lake in its center. Hydrothermal activity is focused mainly within the summit depression with most of the vents located proximal to the lava lake. Isolated active and inactive chimneys and mounds are widespread throughout the summit depression and occur on both volcanic (pillow lava) and hydrothermal (sulfide rubble and hydrothermally cemented breccias) substrates. The large volume of sulfide rubble, together with the nature of the sulfide structures, indicates that hydrothermal activity has been episodic but ongoing for a long period of time (hundreds to thousands of years). On the basis of the distribution of hydrothermal deposits, we propose a model of alternation between tectonic and volcanic control on hydrothermalism at Lucky Strike Seamount. Midsegment melt focusing produces a spatially and temporally stable heat source that sustains focused high-temperature hydrothermal activity over long time periods. During periods of amagmatic extension, active faulting within the summit depression provides multiple, near-surface fluid flow pathways for discharge of high-temperature fluids and widespread deposition of massive sulfides. During eruptive events, rapid effusion of very hot lava creates a lava lake and hyaloclastite deposits. The new sheet flows form a cap on the hydrothermal system, and fluid upflow is reorganized. Discharge of high-temperature fluids is restricted to isolated sites with relatively high permeability, for example, the edges of the lava lake. Much of the upwelling hydrothermal fluid pools in the subsurface, conductively cools, and mixes with entrained seawater before discharging as widespread low-temperature diffuse flow. Hyaloclastites become cemented, further augmenting the sealing of the system. Present-day activity at Lucky Strike Seamount represents this locally volcanically controlled phase of activity, despite the segment as a whole being dominantly amagmatic

The GEOTRACES Intermediate Data Product 2017 (IDP2017) is the second publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2016. The IDP2017 includes data from the Atlantic, Pacific, Arctic, Southern and Indian oceans, with about twice the data volume of the previous IDP2014. For the first time, the IDP2017 contains data for a large suite of biogeochemical parameters as well as aerosol and rain data characterising atmospheric trace element and isotope (TEI) sources. The TEI data in the IDP2017 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at crossover stations. The IDP2017 consists of two parts: (1) a compilation of digital data for more than 450 TEIs as well as standard hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing an on-line atlas that includes more than 590 section plots and 130 animated 3D scenes. The digital data are provided in several formats, including ASCII, Excel spreadsheet, netCDF, and Ocean Data View collection. Users can download the full data packages or make their own custom selections with a new on-line data extraction service. In addition to the actual data values, the IDP2017 also contains data quality flags and 1-σ data error values where available. Quality flags and error values are useful for data filtering and for statistical analysis. Metadata about data originators, analytical methods and original publications related to the data are linked in an easily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2017 as section plots and rotating 3D scenes. The basin-wide 3D scenes combine data from many cruises and provide quick overviews of large-scale tracer distributions. These 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of tracer plumes near ocean margins or along ridges. The IDP2017 is the result of a truly international effort involving 326 researchers from 25 countries. This publication provides the critical reference for unpublished data, as well as for studies that make use of a large cross-section of data from the IDP2017. This article is part of a special issue entitled: Conway GEOTRACES - edited by Tim M. Conway, Tristan Horner, Yves Plancherel, and Aridane G. González
