The long range transport of persistent and semi-volatile organics was studied in this article using a coupled atm-ocean circulation model. DDT was found mostly in soils and had the longest residence time in the soil and ocean. DDT travels vertically in oceans by attaching to particles and suspending downward. About 30% of DDT is stored in particulate matter in the oceans. The global scale substance transport in the environment is ultimtely determined by atmospheric circulation. After a decade of simulation 12% of global DDT was found to accumulate in the Arctic.

ER admissions and the Red Tide
This article deals with the relevancy of emergency room admissions for gastrointestinal issues to Florida Red Tide Blooms. Exposure to Red Tide aerosols has been known to cause neurological as well as respiratory illnesses, but it can also cause gastrointestinal complications due to ingestion of shellfish and fish. During Florida Red Tide blooms, ERs saw a 40% increase in admissions for gastrointestinal illness.
Chinook Salmon Growth during the 1998 El Nino and 1999 La Nina
The following article researches the growth rate of juvenile Chinook Salmon during El Nino and La Nina periods. The salmon experienced greater growth during strong El Nino events as opposed to the La Nina event. This was due to elevated temperatures, lower salinity, and greater freshwater outflow.
