Spectral analysis of spatial series of oceanographic variables


, : Spectral analysis of spatial series of oceanographic variables. Journal of Experimental Marine Biology and Ecology 30(2): 147-164

Time series of fluorescence, temperature, concentration of nitrite, and of nitrate + nitrite, obtained in the upwelling zone off northwest Africa, were analyzed by power spectral techniques, after application of a first difference filter. In 3 runs, coherence between fluorescence and temperature was significant at all frequencies lower than 0.04-0.13 cycles/min; in another 3 runs, coherences showed a drop at low frequencies. Coherences between the remaining pairs of variables were significant at the lower frequencies studied in most cases. Significant coherences between nitrate + nitrite and temperature were found at wider frequency ranges than for fluorescence and temperature. Nitrite showed higher coherences with fluorescence and lower ones with temperature than nitrate + nitrite, as would be expected from the involvement of phytoplankton in the production of nitrite. Some points concerning coherence between fluorescence and physical variables, as represented by temperature, are discussed.

In 1985-1993 there were 37,046 deliveries in the Maternity and Gynaecological Ward of District General Hospital in Radom. In 4873 (13.15%) cases the caesarean section (c.s) was performed. Primiparas constituted 39.3% and the repeated c.s. was carr...
