5th IMW Sampling Mission: Brazil, Chile, Peru and Ecuador 



Eighty nine samples from 12 sites in Brazil, 7 sites in Chile, 2 sites in Peru and 2 sites in 

 Ecuador were collected between March 15 and May 2, 1992 in a single sampling mission. With a 

 few exceptions, samples were collected at the pre-selected sites. In Brazil, for example, Bragan?a 

 and Macei6 replaced Belem and Aracaju, respectively. The pre-selected Isla Caviana was deleted 

 while Sao Luis and Guanabara Bay were added to the sampling list. In Chile, 2 sites (Puerto 

 Montt and Concepcibn) replaced Valdivia. Arica was added to the sampling list to give a better
