Brief résumé of scientific studies that could be profitably undertaken in the Galapagos Islands.

1. Meterological observations. These are at present wholly lacking. Little is known about the amount and variation of rainfall on any of the Islands. Stations with recording instruments should be established at strategic points. 

2. Ocean currents. It is highly desirable to have tidal movements recorded over considerable periods of time by means of tide gauges. The strength, fluctuation, salinity, chemical, and biological constituents of the ocean currents in the vicinity of, and [[strikethrough]]possibly [[/strikethrough]] through, the Islands constitute data of great scientific importance. These studies may throw light on the movements of marine mammals and fishes in the Galapagos region and perhaps make possible future regulations looking toward the conservation and perpetuation of economically important ^[[species]] [[strikethrough]]fishes.[[/strikethrough]]

3. Photographing and mapping the Islands from the air. The Galapagos Islands need to be accurately mapped and to have their individual positions more exactly determined. It is not necessary to discuss the value of good maps or charts from the point of view of navigation. The only means of carefully, expeditiously, and economically mapping islands such as the Galapagos is from the air. These photographic maps would show the extent and nature of the respective land masses forming the archipelago, and, if taken from proper altitudes, would reveal shoals, submerged rocks, and the configuration of the ocean bottom about the shores of the Islands. The physiographic features
