Sea Level Trends - This lesson is designed as an introductory activity exploring one facet of global climate change — sea level change. Students will access real scientific data to investigate and compare long-term changes in sea level from different coastal locations around the United States.

Heat Capacity - Why does coffee take so long to cool down? Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? How can buoys help us explore these questions? In this hands-on introduction to heat capacity by the Bridge and COSEE NOW, students explore the concept and its effects on our daily lives. Students use ocean observing system data to investigate why water acts as a thermal buffer and the practical applications this has.

Sea State - Being able to accurately forecast the conditions at sea, or sea state, has been the goal of explorers, sailors, and fishermen for thousands of years. Now, through the use of ocean observing systems, we can not only predict, but pinpoint, exactly what the sea state will be like before leaving the dock.

Cold One Day, Warm Another? - Ever wondered why water temperatures at the beach can be so different from day to day? Learn how upwelling influences beach water temperatures in this Data Tip, a collaboration with the U.S. Army Corps of Engineers Field Research Facility.

Waves: An Alternative Energy Source - Our lives have become so dependant on non-renewable energy sources that it is hard to imagine life without them. But what about renewable or sustainable energy sources? Explore the possibility of waves as an alternative energy source and use data from US ocean observing system (OOS) buoys to determine the feasibility.

Tsunami - On Saturday, December 25, 2004 an underwater earthquake caused tsunamis to crash into coasts around the Indian Ocean basin, claiming over 100,000 lives. What are the underlying physical and geological forces that create these devastating natural phenomena?

Tides - Tides dictate the lives of the marine organisms which live within their reach, as well as the plans of those who live, work, and play near the coast. This month we examine the factors that influence the tides and use NOAA tide data to make tidal predictions.

Oceanography 101 - To comprehend the system as a whole, scientists must cross the boundaries of disciplines. This month we focus on a unique resource which has gone beyond the typical boundaries of both science and education -- Classroom BATS (Bermuda Atlantic Time-series Study). Classroom BATS helps science teachers to use real ocean data to conduct inquiry-based learning in their grade 6-12 classrooms.

Tip of the Iceberg - Icebergs are just a chip off the old block ... of a glacier, but can you imagine one the size of Rhode Island? Learn how icebergs are formed and why the tracking of them is so important to the shipping industry. Then, chart the path of two Antarctic icebergs.
