23. Physical, chemical, and biological observa- 

 tions on the Continental Shelf, Nova Scotia to 

 Long Island, 1964-66. By John B. Colton, Jr., 

 Robert R. Marak, Samuel R. Nickerson, and 

 Ruth R. Stoddard. 1968, 195 pp. on 3 micro- 

 fiche. 



ABSTRACT 

 This report lists and illustrates results obtained 

 during eight quarterly environmental surveys: De- 

 cember 1964 and 1965, March 1965 and 1966, May- 

 June 1965 and 1966, and September 1965 and 1966. 

 The purpose of these surveys was to determine the 

 seasonal distribution of temperature, salinity, dis- 



solved oxygen, and chlorophyll in an area support- 

 ing an intensive commercial fishery. 



24. Hydrographic observations in Tampa Bay, 

 Florida, and the adjacent Gulf of Mexico — 

 1965-66. By Carl H. Saloman and John L. 

 Taylor. 1968, 393 pp. on 6 microfiche. 



ABSTRACT 

 The hydrographic data include water temperature, 

 salinity, total phosphorus, total nitrogen, oxygen, 

 pH, turbidity, chlorophyll A, B, and C, astacin and 

 nonastacin carotenoids, primary productivity based 

 on chlorophyll A extraction, primary productivity 

 by the oxygen light- and dark-bottle method, and 

 ultraviolet absorption. Methods of collecting and 

 analyzing samples are described. Tables summarize 

 the data by mean, range, number of observations by 

 month and year, and by area. All observations were 

 made as part of continuing estuarine research in 

 Tampa Bay and vicinity. 



25. Oceanic conditions in the northwestern 

 Gulf of Guinea, Geronimo Cruise 3, 10 Feb- 

 ruary to 21 April 1964. By Julien R. Goulet, 

 Jr., and Merton C. Ingham. 1968, 48 pp. on 

 1 microfiche. 



ABSTRACT 

 This atlas comprises a series of horizontal and 

 isopycnic sections. The distributions of temper- 

 ature, salinity, and dissolved oxygen are shown on 

 the 0-, 20-, 50-, 100-, 200-, and 400-m. horizontal 

 surfaces, and on the 25- and 26-g/l isopycnic sur- 

 faces. Topographies of the thermocline and the 

 25- and 26-g/l isopycnic surfaces are shown also. 



26. Oceanic conditions in the northwestern 

 Gulf of Guinea, Geronimo Cruise 4, 5 August 

 to 13 October 1964. By Merton C. Ingham, 

 Julien R. Goulet, Jr., and John T. Brucks. 

 1968, 50 pp. on 1 microfiche. 



ABSTRACT 

 This atlas comprises a series of horizontal and 

 isopycnic sections. The distributions of tempera- 

 ture, salinity, dissolved oxygen, and dissolved phos- 

 phate-phosphorus are shown on the 0-, 20-, 50-, 

 100-, 200-, and 400-m. horizontal surfaces, and on the 

 25- and 26-g/l isopycnic surfaces. Topographies 

 of the thermocline and the 25- and 26-g/l isopycnic 

 surfaces are shown also.
