Internet-based modules link classrooms with studies of New Jersey's coastal ocean. Interdisciplinary projects use real-time or near real-time data to support science concepts: history of oceanography; how and why ocean data is collected; impact of physical factors on phytoplankton, fisheries. Students use data to plot sea surface temperatures and currents, predict ocean weather conditions, and more. ... Full description.

This article describes a new method of studying climate change. A previously unnoticed cooling trend that persisted for a millennium caused enough ice to build up in Antarctica's Ross Sea that thousands of Adelie penguins abandoned their colonies beginning about 2,000 years ago. The techniques may also help to refine our understanding of climatic change on the southernmost continent. This article ... Full description.
