Around July 10–12, 2017, in the middle of the long, dark Antarctic winter, a rift in the Larsen C Ice Shelf broke through the last few miles of ice to the Weddell Sea and formed a new iceberg. The NOAA National Ice Center has given the Delaware-sized iceberg the designation A-68.

Chad Reese and Chuck Parrett of the Wyoming-Montana Water Science Center measure channel width for a small stream near Helena, Montana. Streams of this size are often measured using an instrument called a flume designed to constrain all flow to an artificial channel with a known mathematical relationship between water level and streamflow.

Taken 7/11/2017 at Grizzly Ranch, Suisun City, CA. USGS biological science technician Breanne Cooney shows kids how to measure the vegetation surrounding waterfowl nests. Density and height of vegetation can influence the survival of waterfowl eggs and chicks and affect their risk of falling prey to ravens, skunks, and other predators.

Preliminary seafloor bathymetry (shown in colors) collected by the USGS research vessel Parke Snavely on July 11, 2017. Relative depths shown in color, superimposed on a shaded-relief map from the June 26 USGS air-photo survey. Note white data gap next to the shore where water was too shallow for the Snavely to map.
