It’s confirmed: both Antarctica and Greenland are losing ice —around 350 billion tons each year—and, as a result, sea level has risen 11.1 millimeters worldwide since 1992. This photo shows a...
A Coral Reef Watch satellite monitors the temperature of the world’s oceans. When ocean waters get too hot, corals release the microscopic algae that provide them with color and, more importantly,...
Recent Antarctic expeditions have documented climate-induced changes to emperor penguin habitats and impacts on how the penguins feed, breed, and raise their young.
Omoo, a Great White Shark ( Carcharodon carcharias ), carries a satellite tag that sends information daily about her movements across the Pacific. Follow her migration real-time . More about the...
A fleet of underwater floats called Argo is deployed at more than 3,000 spots around the world. The floats transmit information about water temperature, salinity, and pressure which scientists use to...
Through the use of satellites and land survey tools, scientists are learning about the effects of climate change on our ocean. By combining data regarding sea level and land elevation, they can see...
Follow a journey with satellite tags placed on bull sharks and tarpon. Both of these large predatory fish are found in coastal in-shore ecosystems and the two species have similar diets. If given the...
'Blue Marble' image of the Earth taken from the VIIRS instrument aboard NASA's most recently launched Earth-observing satellite - Suomi NPP . This composite image uses a number of swaths of the Earth...
How do we know where ocean animals swim day and night? Scientists are getting snapshots into the daily lives of whales , sharks , and even fish by tagging the animals to track their movements. You’ve...
Humpback whales ( Megaptera novaengliae ) are the most abundant baleen whale in the nearshore waters around the Antarctic Peninsula. They, along with millions of penguins, seals, seabirds, and other...
