ADCP current measurements in the bay of Sept-Îles in 2018
No full textWater velocity profiles were gathered in the Bay of Sept-Îles from the 16th to the 18th of May, 2018, as part of the Canadian Healthy Oceans Network (CHONe II) program. Current profiles were collected using a Teledyne RDI Sentinel V 500 kHz ADCP fixed on a Biosonics BioFin aluminum towing body and towed at a speed of approximately 2 m s−1. The ping frequency and vertical resolution were set to 0.5 Hz and 0.5 m yielding a 50 m depth range. The mean depth of the towing body was 0.9 m and the centre of the first bin was 2.6 m deep. Towed ADCP velocities were smoothed with a 63 ping horizontal moving average and gridded at a resolution approximately equivalent to the distance travelled by the boat in the corresponding time (252 m). Water velocity data were collected inside the bay during flood tide. Repeated passages were also conducted at the mouth of the bay, between the port of Sept-Îles and Pointe à la Marmite during one semidiurnal tide cycle (12 h)
Physical oceanographic data in the bay of Sept-Îles
No full textThis data set contains temperature, salinity, oxygen, fluorescence, turbidity, currents, and lagrangian drift data collected in the bay of Sept-Îles, on the north shore of the Gulf of St. Lawrence, Canada. Five sampling campaigns were conducted from May to September of 2017, to assess seasonal variations in the oceanographic conditions. An additional campaign was conducted in May 2018, focusing on the measurement of currents. These surveys covered the inside of the bay and the nearby archipelago. The bay of Sept-Îles has recently been the subject of a multidisciplinary study by the Canadian Healthy Oceans Network (CHONe II) because it is a heavily industrialized and urban coastal area at Canadian midlatitudes. It is therefore a good site to study the impact of such human presence on adjacent marine ecosystems. The objective of this data set was to enable the development and calibration of hydrodynamic and biogeochemical models of the bay, which was hindered by scarce knowledge of the environmental conditions. Water properties were collected using a Seabird Electronics SBE19plus and a Sontek CastAway CTD probe. Currents were measured using a towed acoustic Doppler current profiler (ADCP) model Teledyne RDI Sentinel V, and passive surface drifters which used Spot GPS probes
Passive surface drifter data in the bay of Sept-Îles in 2003
No full textLagrangian drift data were gathered by Denis Lefaivre in the Bay of Sept-Îles in 2003 as part of work for the Department of Fisheries and Oceans, Canada (DFO). The drifters were deployed from the small DFO boat Barachois, and consisted of 2 m long by 10.16 cm wide PVC tubes. These were weighted on one end and affixed with a 22.86 cm ring 20 cm from the other, to increase stability. Positions were recorded every 2 minutes by a GPS emitter inside the top 20 cm of the tube, which remained above water. Sampling was done from September 9 to 11, 2003
Physical oceanographic data in the bay of Sept-Îles measured by SBE 19plus CTD probe in 2017
No full textTemperature, salinity, dissolved oxygen, turbidity and fluorescence data were gathered in the Bay of Sept-Îles during the Spring and Summer in 2017, as part of the Canadian Healthy Oceans Network (CHONe II) program. These were profiles were collected during 5 separate campaigns (2 in May, 2 in June, and 1 in September) at 21 stations in the bay and archipelago. On two occasions (late June and September), repeated passages were also conducted at the mouth of the bay, between the port of Sept-Îles and Pointe à la Marmite during one semidiurnal tide cycle (12 h). Although other measurements were collected continuously, CTD data were gathered once every three passages at the beginning, middle, and end of the passage. The data were collected from the local fishing vessel Yvan-Raymond using a Seabird electronics SBE 19plus CTD probe

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
