This image shows colonies of Pavona clavus and branching coral Pocillopora robusta. Once they've sailed to their desired destination, scientists anchor their boat and look for coral to core. The branching coral Pocillopora robusta seen in the sides of this photograph are beautiful but not particularly useful for paleoclimatic research. Others, like the massive coral Pavona clavus that dominates this picture, are perfect: big, easily cored, and sometimes hundreds of years old, ancient enough to produce a long and interesting climatic record.
The Gulf of California appears to be in full bloom in this Sea-viewing Wide Field-of-view Sensor (SeaWiFS) image acquired on March 22, 2001. The distribution of phytoplankton (greenish pixels) in the gulf reveals the turbulent nature of the currents there, particularly in the central and southern portions of this subtropical arm of the Pacific Ocean. The Gulf of California is framed by Mexico's Baja Peninsula on the left and that country's province of Sonora on the right. Phytoplankton blooms are also visible off the west coast of Baja in this scene. The white pixels are clouds.
Morales Dam in Los Algodones, Baja California, Mexico is the source of water for the Alamo Canal which flows west to Mexicali. Agriculture is the primary user of water diverted at this dam. This diversion leaves the bed of the Colorado River without enough water to sustain its flow.
