Copepods

Plankton samples were taken either superficially or vertically from different depths to the surface off the coast of Brazil (4 degrees 57 minutes N and 34 degrees 42 minutes S). These plankton samples belong to the collections of the Instituto Oceanográfico, USP. Some were donated by foreign institutions like the Japanese Government (samples from the \"Toko Maru\" cruise) and The Woods Hole Oceanographic Institution (\"Atlantis\" cruise n. 247 along 36°S lat.). Some were donated to the Instituto by the Brazilian Navy. The others were collected by the Institutos staff for several purposes (hydrographical, biological and fisheries research).
