Full text linkThis report describes the mooring operations conducted during RV Ronald H. Brown cruiseRB0901 between 15 April and 5 May 2009.These mooring operations were completed as part of the United Kingdom Natural EnvironmentResearch Council (NERC) funded RAPID-WATCH Programme to monitor the AtlanticMeridional Overturning Circulation at 26.5°N. The primary purpose on this cruise for the UKteam was to service the RAPID Western Boundary moorings while the US team worked on theWestern Boundary Time Series project.Cruise RB0901 was from Charleston, South Carolina to Charleston, South Carolina andcovered the Western Boundary moorings deployed on cruises SJ08 and RB0701. This cruisewas the seventh annual refurbishment of the Western Boundary section of an array of mooringsdeployed across the Atlantic in order to continuously observe the Atlantic MeridionalOverturning Circulation (MOC). This array will be further refined and refurbished duringsubsequent years.The instruments deployed on the array consist of a variety of current meters, bottom pressurerecorders, and CTD loggers, which, combined with time series measurements of the FloridaChannel Current and wind stress estimates, will be used to determine the strength and structureof the MOC at 26.5°N.(http://www.noc.soton.ac.uk/rapid
RRS Discovery Cruise DY039, 17 Oct - 01 Dec 2015, Southampton, UK to Nassau, Bahamas. RAPID moorings cruise report
No full textThis cruise report covers scientific operations conducted during RRS Discovery Cruise DY039. The purpose of the cruise was the refurbishment of an array of moorings spanning the latitude of 26.5°N from the Bahamas to the Canary Islands. Cruise DY039 departed from Southampton, UK on Saturday 17 October 2015, calling at Tenerife, Spain and Nassau, Bahamas before ending in Nassau, Bahamas on 21 November 2015.The moorings are part of a purposeful Atlantic wide mooring array for monitoring the Atlantic Meridional Overturning Circulation and the associated heat transport. The array is a joint UK- US programme and is known as the RAPID-MOCHA array.During DY039 moorings were serviced at sites: EBH4, EBH4L, EBH3, EBH2, EBH1, EBH1L, EBHi, EB1, EB1L, MAR3, MAR3L, MAR2, MAR1, MAR1L, MAR0, WB6, WB4, WB4L, WBH2, WB2, WB2L, WB1, WBADCP and WBAL. Sites with suffix ‘L’ denote landers fitted with bottom pressure recorders. RAPID-AMOC continues the measurements at 26°N started with the RAPID and RAPID-WATCH programmes and through the ABC Fluxes project extends the measurements to include biological and chemical measurements in order to determine AMOC links to climate and the ocean carbon sink on interannual-to-decadal time scales. This is the first deployment of the ABC Fluxes biogeochemical samplers and sensors to the array (aside from initial oxygen sensors that were deployed in 2014).The ABC Fluxes sensors include pCO2 sensors, pH sensors, additional oxygen sensors and autonomous water samplers to collect samples for nutrient and carbonate chemistry analysis following mooring recovery.Additionally the RAPID telemetry MkIII system was deployed for the first time on the array at EBHi with 6 data pods set to release over the 18-month deployment period. 24 temperature sensors and 2 75kHz ADCPs were also added to mooring WB1 for the MerMEED project.Mooring EB1L was not able to be recovered but a replacement was deployed. A sediment trap mooring NOGST was also recovered and redeployed for the Ocean Biogeochemistry and Ecosystems Group at the NOCS.CTD stations were conducted throughout the cruise for purposes of providing pre- and post- deployment calibrations for mooring instrumentation (including oxygen and carbonate chemistry sampling) and for testing mooring releases prior to deployment.Shipboard underway measurements were systematically logged, processed and calibrated, including: surface meteorology, 5m depth sea temperatures and salinities, water depth, and navigation. Water velocity profiles from 15 m to approximately 800 m depth were obtained using the two vessel mounted Acoustic Doppler Current Profilers (one 75 kHz and one 150 kHz)

Full text linkThis report describes the mooring operations conducted during RRS Charles Darwin Cruise CD170 and RV Knorr Cruise KN182-2. Cruise CD170 was conducted between 2 April 2005 and 27 April 2005, and Cruise KN182-2 was conducted between 2 May 2005 and 26 May 2005.These cruises were completed as part of the United Kingdom Natural Environment Research Council (NERC) funded RAPID Programme and the United States of America National Science Federation (NSF) funded MOCHA Programme to monitor the Atlantic Meridional Overturning Circulation at 26.5ºN. The primary purpose of these cruises was to service the 26.5ºN mooring array deployed in 2004 during RRS Discovery cruises D277 and D278 (cruise report number 53).Cruise CD170 was from Tenerife to Bermuda, and covered the Eastern Boundary and Mid-Atlantic Ridge moorings deployed on D277. On arrival in Bermuda equipment and personnel were transferred to the RV Knorr, with Cruise KN182-2 covering the Western Boundary moorings deployed on Cruise D278. These cruises are the first annual refurbishment an array of moorings deployed across the Atlantic in order to set up a pre-operationalprototype system to continuously observe the Atlantic Meridional Overturning Circulation (MOC). This array will be further refined and refurbished during subsequent years.The mooring array deployed in 2004 consisted of 19 moorings from the National Oceanography Centre, Southampton (NOC – formerly the Southampton Oceanography Centre), with 3 from the Rosenstiel School of Marine and Atmospheric Science (RSMAS), University of Miami. The replacement array deployed in 2005 consisted of 24 NOC moorings, and 5 RSMAS moorings. Moorings are focused at the Eastern and Westernboundaries, along with a grouping at the Mid Atlantic Ridge.The instruments deployed on the array consists of a variety of current meters, bottom pressure recorders and CTD loggers which, combined with time series measurements of the Florida Channel Current and wind stress estimates, will be used to determine the strength and structure of the MOC at 26.5ºN

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
