    With the opening of the Woods Hole Oceanographic Institution in July 1931, there was inaugurated a program of investigations in the deep waters of the western North Atlantic for which there had long been a great need. ...
  • Short period vertical oscillations in the western basin of the North Atlantic 

    Seiwell, Harry Richard (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1937-05)
    Because of general interest in the subject of vertical oscillations in the sea and because such information is scanty for the ocean basins, an investigation of the question in the western North Atlantic was initiated by ...
  • The minimum oxygen concentration in the western basin of the North Atlantic 

    Seiwell, Harry Richard (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1937-05)
    With the advance in knowledge of oceanic circulation there now exists a demand for additional identifying properties which will serve to trace the origin and movements of water masses in the sea, and to check earlier ...
  • The sediments of the continental shelf off the eastern coast of the United States 

    Stetson, Henry C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1938-07)
    Our knowledge of clastic, shallow-water sediments over any considerable area of ocean floor is very generalized and leaves much to be desired. The notations concerning the character of the bottom found on all charts are ...
  • Circulation in upper layers of southern North Atlantic deduced with use of isentropic analysis 

    Montgomery, Raymond B. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1938-08)

  • Application of the distribution of oxygen to the physical oceanography of the Caribbean sea region 

    Seiwell, Harry Richard (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1938-09)
    Observational data for this discussion were obtained principally during the two cruises of the oceanographic research ship, "Atlantis," to the Caribbean Sea March 7 to May 5, 1933 (stations 1487-1610) and February 2 to ...
  • On the local dissipation of natural fog 

    Houghton, Henry G.; Radford, W. H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1938-10)
    It is submitted that the hazards of landing aircraft in fog could be greatly reduced by providing relatively small clearings into which approaching planes could be safely guided by radio or other navigational aids which ...
  • On the measurement of drop size and liquid water content in fogs and clouds 

    Houghton, Henry G.; Radford, W. H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1938-11)
    A short critical review of possible methods for the measurement of the size of fog particles is presented. It is concluded that the only suitable method of obtaining the distribution of drop sizes present in a given fog ...
  • Fluid mechanics applied to the study of atmospheric circulations. I. A study of flow patterns with the aid of isentropic analysis. 

    Rossby, Carl-Gustaf; Namias, Jerome; Simmers, Ritchie G. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1938-12)
    This paper constitutes Part I of a report on certain investigations which have been in progress at the Massachusetts Institute of Technology during the past few years and which have been supported in part with funds ...
  • Thermoconvective eddies in air : application to meteorology 

    Avsec, Dusan (E. Blondel la Rougery : Gauthier-VillarsWoods Hole Oceanographic Institution, 1939)
    The object of the present work is a study thermoconvective eddies in a layer of air heated uniformly from below. Being given the importance that these eddies present in meteorlogical phenomena, we have tried to attain three ...
  • The effect of short period variations of temperature and salinity on calculations in dynamic oceanography 

    Seiwell, Harry Richard (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1939-11)
    This paper is a discussion of possible discrepancies in computations of ocean currents (based on horizontal variations of dynamic topography calculated from arbitrary deep lying reference surfaces), because of time ...
  • Observations of vertical humidity distribution above the ocean surface and their relation to evaporation 

    Montgomery, Raymond B. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1940-02)
    In order to obtain information on the effect of eddy viscosity and eddy diffusion at the boundary between sea and atmosphere, simultaneous measurements of humidity at two, three or four levels between 1 and 38 meters ...
  • Report on an experiment in five-day weather forecasting 

    Allen, R. A.; Fletcher, R.; Holmboe, J.; Namias, Jerome; Willett, Hurd C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1940-04)
    The following report is presented as a statement of progress made at the Massachusetts Institute of Technology (M.I.T.) in the investigation into the possibility of extending the range of reliable weather forecasts. This ...
  • Preliminary report on long-period variations in the transport of the Gulf Stream system 

    Iselin, Columbus O’Donnell (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1940-07)
    In 1937 the Woods Hole Oceanographic Institution and the Bermuda Biological Station for Research agreed to cooperate on a five year program of observations. This was designed to throw light on the general problem of ...
  • Some effects of shearing motion on the propagation of waves in the prevailing westerlie 

    Garstens, M. A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1941-04)
    In recent years great interest has developed in the study of the role of the semipermanent centers of action as they affect weather conditions averaged over several days. An examination of the daily synoptic and upper ...
  • Observations of atmospheric radiation 

    Brooks, Frederick A, (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1941-10)
    Atmospheric radiation is the primary variable in nocturnal cooling, although wind has greater influence on the temperature of surface air. Since temperature inversions near the ground cannot be formed unless surfaces are ...
