Galapagos Islands

The existence of a species of tomato on the Galapagos Islands was first noted by Charles Darwin. Despite a moderate level of variation, Lycopersicon cheesmanii Riley is considered the only tomato species on the islands. All populations examined exhibited morphological and physiological characteristics that clearly...

Some ridge sections are underlain by mantle melt anomalies, or hot spots, such as at the Azores and Galapagos Islands. These are marked by the stars in Figure 19.1 and data points 12 and 13 in Figure 19.5. Mantle upwelhng beneath both these ridge sections has abnormally thickened the oceanic crust to at least about 10 km. Most of the 47 known hot spots lie more than 500 km from a ridge axis. The Hawaiian islands are a notable example.

Around deep-sea vents lives a very interesting species of animal the tubeworm. Some tubeworms can grow to be almost 8 feet (3 m) long. They were first discovered in the 1970s around some hydrothermal vents near the Galapagos Islands off the coast of South America. Since then many tubeworms have been found at deep-sea vents all over the world.

When Charles Darwin was climbing the rocks of the Galapagos Islands—pursuing the finches that would eventually bear his name—he must have cut his finger occasionally or scraped a knee. Young adventurer that he was, he probably paid no attention to the little stream of blood trickling out. Pain was a fact of life to the intrepid island explorer, and it had to be borne patiently if any work were to get done. 

An examination of Figure 6 also illustrates other problems with marine shell samples. Four samples from the environment of the Galapagos Islands ranged from a little more than —4.0% to a little less than +0.5%. This equates to an apparent variation of ca. 850 years between...

Propylene has the same general characteristics found for the other hydrocarbons. Leg I concentrations vary from 3.43 0.49 X 10 ml/l near the Galapagos Islands to 0.59 0.07 X 10" ml/l for an area located s 1500 miles southeast of Hawaii. Leg II exhibits what appears to be a... 

Ethane concentrations exhibit the same type of relative constancy as methane. The only variable and high concentrations (relative to open ocean values) of 0.50 X 10 ml/1 are found near the Galapagos Islands and Ecuador. There is good agreement between the average concentration found in 1972 ( 0.20 X 10" ml/1.) and 1974 (0.28 X 10 ml/L).
