Sulfide minerals
Examples of sulfide minerals that occur at hydrothermal vents and are being studied by Amy Gartman: (left to right) sphalerite, an ore of zinc that often contains iron ([Zn,Fe]S); cubes of pyrite, rich in iron (FeS2); and covellite, containing copper and sulfur (CuS).The pyrite cubes are a little more than half an inch on a side.

Sunset State Beach webcams
USGS Pacific Coastal and Marine Science Center in Santa Cruz, California installed these two video cameras, pointed at the shoreline. The cameras collected imagery every half hour for 10 minutes, during daylight hours. The images are stored in the cloud and are used to study coastal variations through time, like wave, shoreline, and sandbar dynamics.

Thawing Permafrost, Alaska
Thawing permafrost on various peatlands in Alaska. Permafrost thaw results in ground subsidence and inundation that kills black spruce and other understory plants living on the permafrost plateau. The black spruce forests found on permafrost plateaus are replaced with sedge- and moss-dominated bogs and fens, altering the ecosystem structure and function.
