This web-based activity tackles the broad reasons for undertaking ocean exploration - studying the interconnected issues of climate change, ocean health, energy and human health. Students examine the types of technology ocean scientists use to collect important data.
In this activity, students model circulation in gyres, explore characteristics of gyres found around the world, and predict the climate impacts of changes to the circulation in these gyres and climate on adjacent land. Gyres, large systems of rotating ocean currents, play an important role in Earth's climate system.
This activity utilizes labs, online resources, and student ideas to build an understanding of polar climates, how changes in polar oceans can affect coastal climates, and how changes in polar regions affect climates elsewhere on Earth.
This narrated slide show gives a brief overview of coral biology and how coral reefs are in danger from pollution, ocean temperature change, ocean acidification, and climate change. In addition, scientists discuss how taking cores from corals yields information on past changes in ocean temperature.
This video addresses acidification of the ocean and the ecological and economic implications of the resulting pH change on marine life. It includes information about how ocean acidification resulting from increased absorption of CO2 from the atmosphere is affecting ocean species such as sea urchins and oysters. Scientists from the University of California at Santa Barbara discuss their experiments with sea creatures in acidic sea water. There is an associated lesson plan and classroom activity that has students test the effects of CO2 on water pH.
This static image from NOAA's Pacific Marine Environmental Laboratory Carbon Program offers a visually compelling and scientifically sound image of the sea water carbonate chemistry process that leads to ocean acidification and impedes calcification.
