Giant petrels soared against a clear blue sky, and gentle waves rocked the ship—although the crew didn’t […]

Lead Pollution in Antarctic Waters: Have We Cleaned Up Our Act?

Researchers traveled to the far reaches of Antarctica to determine whether lead levels there have declined since humans started cleaning up their act by halting lead emissions. They found that global warming might be negating some of the good we’ve done, as melting glaciers could release stored natural and industrial lead into the ocean. Carrie […]

Tiny shells tell the history of Antarctic ice

Over the past 10,000 years, the West Antarctic Ice Sheet has gone through long periods of growth and long periods of retreat. Shells from the tiny organisms living in the seawater throughout the millennia can be used to reconstruct the history of times when warmer water from offshore came onto the shelf and weakened the […]

We’re In Deep Heat: trouble boils over in West Antarctica

An international team of researchers shows that rising ocean temperatures along West Antarctic ice shelves are linked to rising warm water from the deep ocean, and that the rate of warming is larger than previously thought. With no indication of a slow down in warming, these findings illuminate on new realities of sea level challenges […]
