      Analytical methods have been developed for the determination of iodate, iodide and particulate iodine in sea water. Iodate is converted to tri-iodide and the absorbance of tri-iodide at 353 nm is measured. The precision ...
    • The marine geochemistry of trace metals 

      Boyle, Edward A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1976-04)
      The marine geochemical cycles of iron, copper, nickel, and cadmium were studied in order to provide a basis for oceanographic models for trace metals. Copper, nickel, and cadmium can be determined in a 100 ml seawater ...
    • The sensitivity and predictability of mesoscale eddies in an idealized model ocean 

      Haidvogel, Dale B. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1976-04)
      Two numerical applications of two-level quasigeostrophic theory are used to investigate the interrelationships of the mean and mesoscale eddy fields in a closed-basin ocean model. The resulting techniques provide a more ...
    • On the midwater fish faunas of Gulf Stream rings with respect to habitat differences between slope water and northern Sargasso Sea 

      Jahn, Andrew E. (Woods Hole Oceanographic Institution, 1976-04)
      Forty-three 1000-in oblique Isaacs-Kidd midwater trawl collections were made on six cruises. In most cases, these were accompanied by 1500-m hydrocasts and plankton tows to 800 m. The fish collections comprise 19,400 ...
    • Functional anatomy of the Macrouridae (Teleostei, Gadiformes) 

      McLellan, Tracy (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1976-05)
