During November-December 1977, a modest physical field experiment was carried out over the wide shelf off northern Peru near 9S. Repeated sections of temperature and absolute current profiles were run along two lines with 60 km alongshore separation. Local winds were moderate, rather uniform and favorable for upwelling throughout the study period....
