Fig. 65. Distribution of temperature off the Lobos Islands, July 17-20. Section showing the possible effect 

 of the rocks upon upwelling. The upper section represents conditions on the sheltered, the lower on the 

 exposed side, of the Lobos de Afuera ; their relative positions are indicated by arrows. The positions of these 

 stations are shown in Fig. 12. 



Table XIX. Phosphate values around Lobos de Afuera 



Stations to the leeward and windward of the Lobos de Afuera are compared with those lying closer 

 inshore and farther offshore. Upwelling off the windward shore of the islands is suggested by the high phos- 

 phate at Sts. WS 696 and 695, whereas at Sts. WS 690 and 691, no farther from land, it is intermediate 

 between inshore and offshore values.
