Scuba-diver scientists from the U.S.G.S, with support teams from the U.S. EPA, the Lower Elwha Klallam Tribe, and Washington Sea Grant, are returning to the mouth of Washington’s Elwha River this week to explore and catalogue the effect of released sediment on marine life following the nation’s largest dam removal effort.

Rock Drilling ‘Threatens’ Scotland’s Geology

Irresponsible drilling of holes into rocks to extract samples threaten to “annihilate” geological features in Scotland, with the general public experiencing defaced outcrop in every setting imaginable – remote beaches and islands, mountain tops, and, lamentably, classic geological sections within statutory protected areas.

Caffeinated Coastal Waters

Red Tide Species Is Deadlier Than First Thought

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.
