ECHEVERRIA, Félix et al. Physicochemical and biological characterization of Sea Water in Mamonal zone (Cartagena Bay) for static antifouling paint testing. Rev.fac.ing.univ. Antioquia [online]. 2007, n.39, pp.7-20. ISSN 0120-6230.

The incrustation of marine organisms (biofouling) affect several submerged metallic structures, like ship hulls. Biofouling frequently induces metal corrosion, reduces the speed of displacement, increases fuel consumption, and increases the frequency of dry-dock operations. Antifouling paints which have the capacity to prevent the marine organisms from contacting the painted surface (by means of biocide release), have been developed in order to mitigate these deleterious effects. Static tests of antifouling paints include immersing painted panels (attached to floating structures), and periodically evaluating its performance. Before conducting these static tests, it is important to characterize the local maritime environment by determining the range of values of the most significant physical, chemical and biological variables. A complete characterization of the sea water in the zone of Mamonal (Cartagena Bay) was conducted; variables such as solar irradiation, light availability, dissolved oxygen, temperature, pH, redox potential, alkalinity, and salinity were measured. In addition, the determination and quantification of the main biological entities present in the samples was also carried out.
