Mangroves: A Filter for Heavy Metals
A mangrove is a forest consisting of various species of mangrove trees growing with their bases submerged in water, at the interface between land and sea. They cover more than three quarters of tropical coastlines, that is to say almost 200,000km². In New Caledonia, they accounts for almost 80% of the island’s western coastline.
Satellites See Unprecedented Greenland Ice Sheet Surface Melt
For several days this month, Greenland’s surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations. Nearly the entire ice cover of Greenland, from its thin, low-lying coastal edges to its two-mile-thick center, experienced some degree of melting at its surface.
