1 Common triggers of an anaphylactic reaction include drugs, such as penicillin, insect stings, foods (peanuts, shellfish), X-ray dye, and latex. 2  The symptoms of anaphylaxis may vary and can include hives, tongue swelling, vomiting, and even shock.  If someone is at risk, avoidance is the best form of treatment.
Ocean regions with high concentrations of phytoplankton will have shades of blue-green depending upon the type and density of the phytoplankton population there. The basic principle behind the remote sensing of ocean color from space is that the more phytoplankton is in the water, the greener it is.
The image on the right represents the movement (flux) of CO 2 into and out of the sea surface of the ocean. 1  Purple to blue colors indicate areas of the ocean where more CO 2 is diffusing into sea surface water than is diffusing from sea surface water out to the atmosphere. 2  Thus, these areas are acting as a carbon sink.
