  Data Tips with this icon contain special step-by-step Microsoft Excel graphing instructions for advanced levels.

Conductivity - Water, regardless of whether it is fresh or saline, serves as one of the best electrical conductors on the planet. Learn about conductivity and its relation to salinity, and use real-time ocean observing system (OOS) data to investigate what factors affect conductivity.

$$$eaweed - Seaweed has been traditionally harvested in Europe, Asia and the Pacific Islands for thousands of years, and today harvesting seaweed is big international business. In this Data Tip, we'll take a look at trade and fisheries data to find out who are the big harvesters and importers.

Iron Fertilization - Using data from the Monterey Bay Aquarium Research Institute, track chemical changes during an upwelling event and investigate the effects of iron enrichment.

Diversity of the Deep - Explore the diversity of organisms living on deep sea hydrothermal vents. The species in these unique communities have evolved to thrive in extreme temperatures and no light. This month's data activity will introduce you to some of the common statistical measurements of diversity as you compare the organisms found at various locations on a hydrothermal vent at the Juan de Fuca Ridge.

  The Dead Zone: A Marine Horror Story - Learn about the cause and implications of the Gulf of Mexico dead zone. Includes maps illustrating the size of the Mississippi River watershed and the dead zone. The data provides water quality measurements, and students are asked to graph dissolved oxygen versus depth. Can you think of potential solutions to the problem?
