CYCLE OF PHOSPHORUS IN GULF OF MAINE 441 Methods of estimating its value are so indirect that little is known of its magnitude under any circumstances. Although our data are admittedly very unprecise and yield only minimal values for the exchange, it is nevertheless of some interest to use it in estimating the coefficient required to account for the transport of phosphate in the Gulf of Maine. The gradient of phosphate concentration is sufficiently uniform throughout the period May-November to permit a single value to be taken at any level as representative of the entire period^ This is not the case during the remainder of the year.

Distribution of density, <Tt, with depth in November, 1935, and Febru- ary and May, 1936, at standard station in the western basin of the Gulf of Maine. Depths in meters measured downward along the ordinate; density, at, measured along the abscissa. calculated the value of A for the boundary of each of the layers, using the data presented in Table VIII for estimating Q and the slopes of the curves in Fig. 3 for dcjds. The result is shown in Table X. The values of A are minimal and are less reliable at the greater depths. The values obtained are not unreasonable. Seiwell considered A to equal 2 C.G.S. units in the thermocline of the tropical Atlantic, whereas values increasing to 50 C.G.S. units have been obtained in various waters (Seiwell, 1935)..
