Farmers, Phantoms and Princes. The Canadian Pacific Railway and Filmmaking from 1899-1919

Le développement des images animées coïncide avec le développement d’importantes campagnes de publicité de la compagnie de chemin de fer Canadien Pacifique. Cette compagnie a vite réalisé le potentiel du nouveau média et misé sut la fascination du public pour le train et le mouvement. En vue d’encourager l’immigration et l’établissement dans l’ouest du Canada, la compagnie a mis en place un vaste système de promotion qui inclut l’utilisation des films. La réalisation des films du Canadien Pacifique se répartit en deux grandes catégories : les films destinés de façon spécifique à des fonctions d’éducation et d’information et les films à vocation de divertissement. Le Canadien Pacifique n’a pas défini au préalable le type de réalisation, mais il facilita une production reliée à l’attraction commerciale de l’époque.The development of motion pictures coincided with the development of active publicity campaigns by the Canadian Pacific Railway Company. It did not take the CPR long to realize the potential of the new medium and capitalize on the public's fascination with train and motion. In order to encoutage immigration and settlement to western Canada, the company developed an extensive system of promotion which included the use of films. CPR filmmaking fell broadly into two categories, those which were designed with a specific intent to educate, inform and persuade and those which were primarily intended as entertainment. If CPR did not define the type of filmmaking rathet it facilitated the production of contemporary appeal

Evaluating the efficiency and temporal variation of pilot-scale constructed wetlands and steel slag phosphorus removing filters for treating dairy wastewater

t r a c t The performance and temporal variation of three hybrid and three integrated, saturated flow, pilot-scale constructed wetlands (CWs) were tested for treating dairy farm effluent. The three hybrid systems each consisted of two CWs in-series, with horizontal and vertical flow. Integrated systems consisted of a CW (horizontal and vertical flow) followed by a steel slag filter for removing phosphorus. Time series temporal semivariogram analyses of measured water parameters illustrated different treatment efficiencies existed over the course of one season. As a result, data were then divided into separate time period groups and CW systems were compared using ANOVA for parameter measurements within each distinct time period group. Both hybrid and integrated CWs were efficient in removing organics; however, hybrid systems had significantly higher performance ( p < 0.05) during peak vegetation growth. Compared to hybrid CWs, integrated CWs achieved significantly higher DRP reduction ( p < 0.05) throughout the period of investigation and higher ammonia reduction ( p < 0.05) in integrated CWs was observed in late summer. Geochemical modeling demonstrates hydroxyapatite and vivianite minerals forming on steel slag likely control the fate of phosphate ions given the reducing conditions prevalent in the system. The model also demonstrates how the wastewater:slag ratio can be adjusted to maximize phosphorus removal while staying at a near-neutral pH. ª 2010 Elsevier Ltd. All rights reserved. Introduction Research for improving constructed wetland (CW) nutrient removal capabilities is motivated by the increasingly stringent worldwide water quality regulations and the often varying treatment performance of existing CWs for treating nutrient rich livestock wastewate

Ocean temperature and salinity in McMurdo Sound, Antarctica in 2016

Ocean salinity was recorded at 10 second intervals by a Seabird Electronics SBE 37 microCAT CTD at a nominal depth of 100 m in McMurdo Sound at 77.6152 °S, 164.8821 °E. The dates covered by the salinity observations at 100 m depth are from 28-10-2016 06:43:11 UTC to 13-11-2016 21:59:51 UTC. The salinity is reported in units of practical salinity. Ocean temperature was recorded at 10 second intervals by a Seabird Electronics SBE 56 thermistor at a nominal depth of 75 m in McMurdo Sound at 77.6152 °S, 164.8821 °E. The dates covered by the temperature observations at 75 m depth are from 28-10-2016 06:43:11 UTC to 13-11-2016 21:59:51 UTC. The temperature is reported in units of °C in the ITS-90 temperature scale

Temperature, salinity and acoustic backscatter observations and tidal model output in McMurdo Sound, Antarctica in 2016 and 2017 - links to original files

Temperature and salinity observations were made at nominal depths of 75 m and 100 m, respectively, by Sea Bird Electronics sensors. Acoustic volume backscatter measurements were made by an ASL Environmental Sciences Acoustic Zooplankton Fish Profiler (AZFP) operating at four-frequencies (125 kHz, 200 kHz, 455 kHz and 769 kHz). The AZFP profiled the top 25 m of the water column in 0.1 m bins. All instruments were deployed through a landfast sea ice cover that was approximately 2 m thick. The WWW Tide and Current Predictor model was used to generate tidal height forecasts for the deployment periods

Tidal height forecast data for Ross Island, Antarctica (2017-11-08 to 2017-11-13)

Tidal height forecast data were produced from the WWW Tide and Current Predictor (http://tbone.biol.sc.edu/tide/tideshow.cgi?site=Ross+Island%2C+Antarctica) for Ross Island, Antarctica, for the period of the 2017 AZFP deployments. The dates covered by the tidal height forecast are from 8-11-2017 00:00 UTC to 13-11-2017 23:50 UTC
