Biological survey of the Panama Canal Zone

exhaustive biological survey of the Panama Canal Zone-will be undertaken in the winter of 1910-11. A part of the fresh-water streams of the Isthmus of Panama empty into the Atlantic Ocean and others into the Pacific Ocean. It is known that a certain number of animals and plants in the streams on the Atlantic side are different from those of the Pacific side, but as no exact biological survey has ever been undertaken the extent and magnitude of these differences have yet to be learned. When the canal is completed the organisms of the various watersheds will be offered a ready means of mingling together, the natural distinctions now existing will be obliterated....

Biological Survey of the Panama Canal Zone (1911)

With the cooperation of several of the executive departments, and of the Field Museum of Natural History, a party of about 10 naturalists was accordingly sent to the zone, and the results so far accomplished have been very satisfactory. Large collections of biological material have been received, including specimens of a considerable number of genera and species new to science. It also seemed important to determine exactly the geographical distribution of the various organisms inhabiting the Isthmus, which is one of the routes by which the animals and plants of South America have entered North America and vice versa. The estimated cost of the survey which would have to be met by the Institution is $11,000...

Biological survey of the Panama Canal Zone (1912)

At first it was intended to confine the collections to the Canal Zone proper, but as the faunal and floral areas extended to the north and south of this region, it was decided to carry the work into the Republic of Panama, a step which met with the hearty approval of that Republic. The work accomplished has been very valuable to science, including collections and observations of vertebrate animals, land and fresh water mollusks, and plants, including flowering plants, grasses and ferns. Special attention will be given during the coming season to vertebrate animals, insects, crustaceans, rotifers and other minute freshwater animals, and also to the microscopic plants known as diatoms. Includes appendix of papers that resulted.

SAIL Panama Canal Zone Project 2008 : Biological Survey of Panama (1910-1912)

During the 18th Annual 2008 SAIL meeting at the Smithsonian Tropical Research Institute in Panama, a suggestion was made for the need to digitize and make available through the Aquatic Commons some of the early documents related to the U.S. biological survey of Panama from 1910 to 1912. With SAIL’s endeavor, a new digital project was born and this presentation describes its process, beginning to final product. The main source consulted for determining copyright clear publications was: Heckadon-Moreno. 2004. Naturalists on the Isthmus of Panama: A hundred years of natural history on the biological bridge of the Americas. 1st English ed. Smithsonian Tropical Research Institute, Panama City, Republic of Panama. (Document contains 26 slides)

Bibliography of the SAIL Panama Canal Zone Project 2008 : a selected bibliography.

During the 18th Annual 2008 SAIL meeting at the Smithsonian Tropical Research Institute in Panama, Vielka Chang-Yau, librarian, mentioned the need to digitize and make available through the Aquatic Commons some of the early documents related to the U.S. biological survey of Panama from 1910 to 1912. With the assistance of SAIL, a regional marine librarian’s group, a digital project developed and this select bibliography represents the sources used for the project. It will assist researchers and librarians in finding online open access documents written during the construction of the Panama Canal, specifically between 1910-1912. As the project progressed, other items covering the region and its biological diversity were discovered and included. The project team expects that the coverage will continue to expand over time.

Caractérisation du pergélisol : application d’une nouvelle méthode afin d’estimer la conductivité thermique à l’aide de la tomodensitométrie

La construction dans l’Arctique nécessite une connaissance précise des propriétés thermiques et géotechniques du pergélisol. La connaissance de ces propriétés est également nécessaire pour le paramétrage des modèles de transfert de chaleur. Des études antérieures ont démontré le grand potentiel de l’utilisation de la tomodensitométrie pour les mesures du volume des composantes du pergélisol et la visualisation de la cryostructure. Une nouvelle approche est proposée pour mesurer la conductivité thermique du pergélisol. Les objectifs généraux de ce projet sont (1) d’élaborer une nouvelle méthode de caractérisation du pergélisol à l’aide de la tomodensitométrie et de modèle éprouvés et (2) de comparer et mettre au point une méthode novatrice pour mesurer la conductivité thermique et des paramètres géotechniques. Les résultats démontrent que les tests effectués à l’aide de la tomodensitométrie donnent des résultats d’une valeur scientifique comparable aux autres méthodes existantes de mesure de déjà existantes de conductivité thermique du pergélisol.
