Isla Verde, San Juan, Puerto Rico
The urban reef at Isla Verde supports various species of protected corals, sea turtles, and crustaceans, as well as many Caribbean fish. It also protects the International Airport and numerous homes and resorts on the coast.

RestoreNet treatments
RestoreNet locations are testing commonly used restoration techniques, including pitting, mulching, and above-ground micro sites. This photo shows the mulching treatment, which can increase soil moisture and lead to higher plant survival under some conditions.

Survey at a dam-removal and culvert-retrofit site
USGS staff survey the Mill River near the former Hopewell Mills Dam site in Taunton, Massachusetts. Surveys at the dam-removal and culvert-retrofit sites provided topographic and bathymetric data for hydraulic models developed for the study.

Image of the Week - Elwha River Dam Removal
In September 2011, the largest dam removal project in U.S. history began.
Two dams built on the Elwha River in the early 1900s created two reservoirs in northwestern Washington. They also greatly reduced the amount of sediment flowing to the river’s delta and blocked salmon migration upstream into Olympic National Park.

Webcam check at Halema‘uma‘u
HVO geologists made a routine visit to the webcam monitoring Halema‘uma‘u. No changes were observed in the pit, but views were hampered by poor weather and thick fog.

10 frame 3D reconstruction
Digital 3D reconstruction of lake bottom using 10 photo frames taken by the dive camera system. This reconstruction allows us to gain more insight about the lake bottom since elevation has been added to the photographs.
