The marine geochemistry of methane
In the highly productive coastal surface waters near Walvis Bay, methane is present in concentrations considerably above those which would be predicted from solubility equilibrium with the atmosphere. A one dimensional diffusive model and a one dimensional horizontal advection diffusion model were …

Transient structure in benthic communities : the effects of oxygen stress, burial and high rates of sedimentation
The influence of natural short-term fluctuations in environmental parameters on three components of transient benthic invertebrate community structure: abundance of individuals and species, biomass of individuals, and species diversity, were investigated in this study. The effect of low …

Dissolved inorganic and particulate iodine in the oceans
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 of this method is ca. ±3%. Iodide is first separated from most other anions by …

Nutritional ecology of Agalma okeni and other siphonophores from the epipelagic western North Atlantic Ocean
… veliger larvae, sergestids, mysids, euphausiids, and small fish, though laboratory experiments showed that not all could eat nauplii. Species which could capture Artemia nauplii usually required 2 - 4 hours to digest them, while large prey took 7 - 18 hours to be digested. Since a single …
