SNOMS Swire NOCS Ocean Monitoring System: diary of the system development and installation on the MV Pacific Celebes in 2006 and 2007
Get PDFThe SNOMS project brings together the resources of the United Kingdom’s National Oceanographic Centre, Southampton (one of the world’s leading centres for marine research) and The Swire Group (a major multinational corporation) to make a significant contribution towards improving our understanding of the role of the oceans in controlling concentration of carbon dioxide in the atmosphere and hence the worlds climate.The Swire Group Charitable Trust funded the design, assembly and installation of a scientific data collection system on their ship the MV Pacific Celebes. The system is now providing data from areas where no or little data exists particularly in the Indian Ocean, Red Sea and Mediterranean. It links with and connects on-going observations in the Atlantic. Data from the system supports projects both at NOC and elsewhere including the IOCPP (International Ocean Carbon Coordination Project).This report provides an illustrated diary of the progress of the project between signing of the contract between the Swire Group and NOC in March 2006 and the installation of the working system on the MV Pacific Celebes in June 2007. A new type of system for monitoring the partial pressure of CO2 at the sea surface had to be developed which could run autonomously of NOC with only periodic servicing by the ship’s crew. This was done by designing a simple tank system to contain temperature, conductivity and dissolved oxygen sensors built by Aanderaa and the new CO2 device the “ProCO2” developed by ProOceanus in Canada. This would be used with the ProOceanus total gas Pressure device the GTD.The system was assembled and tested at NOC before its first sea trial on the P&O ferry MV Pride of Bilbao in November 2006. Modifications were made after this trial. A longer trial was carried out on the Pride of Bilbao from February to April 2007. The system was shipped to Singapore in May 2007, and installation was completed in Jakarta on 4 June 2007
First Annual Report on the SNOMS Project
Get PDFIn 2006 the Swire Group Charitable Trust funded the development and installation of a system to measure the partial pressure of carbon dioxide dissolved in the surface ocean from one of the Swire Group’s ships. The system was fitted on the MV Pacific Celebes in June 2007. The Celebes trades on a global route out of Singapore. It takes about 5 months to go round the world. Measurements are made of the partial pressure of carbon dioxide in seawater and air, also of water temperature, salinity, dissolved oxygen and nitrogen, air temperature, pressure and humidity. Data are collected automatically on the ship and then transmitted to shore where they are transferred to a public web page. The data are vital to enabling the prediction of change in the ocean’s ability to absorb carbon dioxide and hence the rate of climate change induced by anthropogenic release of carbon dioxide. Key observations to date are: (1) potentially high inputs of gasses into the ocean during sustained storm conditions, (2) a substantial natural flux of carbon dioxide into the atmosphere of the western equatorial Pacific under the ‘La Nina’ conditions of 2007, (3) the potential of the western North Atlantic to absorb more carbon dioxide in autumn than previously predicted
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
