Phosphorus is an essential element to all life and this journal article describes how. This article illustrates phosphorus occurrence in the Earth's crust and its sources and sinks in the ocean. I learned that with the advent of new techniques, we have gained a greater understanding of the forms of phosphorus in the marine environment and how specific organism utilize each of these phosphorus pools. The phosphorus cycle is a very complex cycle and is not fully characterized yet.
The impacts of El Niño and La Niña on the U.S. climate during northern summer are analyzed separately in this journal article. Over most of North America during La Niña events a continental-scale peculiar high dominates, which leads to hot and dry summers over the central United States. The impacts of El Niño over North America, however, are weaker and more variable. In this article, there are many Figures that illustrate these impacts of El Niño and La Niña on the U.S. climate during northern summer.
