A Devils Hole pupfish swims above the algae mat that typically covers the shallow spawning shelf in Devils Hole. 

USGS Cooperative Research Unit graduate student Ambre Chaudoin monitors pupfish spawning behavior in Devils Hole, the only habitat for endangered Devils Hole pupfish.The USGS cameras that captured effects of an earthquake on Devils Hole can be seen in this picture.

After being caught by mist nets, birds are anesthetized while a small transmitter is inserted into the abdominal cavity. The surgical procedure takes less than 30 minutes. Birds recover quickly and are ready for release within an hour of surgery. This photo shows a male curlew with a black leg flag inscribed "H8".

The Long-billed Curlew (Numenius americanus) is the largest North American shorebird and is characterized by its long and decurved bill.

A tiny brittle star (the central disc is smaller than a dime) clings to the branches of a soft coral in a sample bucket brought into the shipboard laboratory from a submersible dive. This creature makes its home on the deep, dark ocean floor.

High resolution satellite imagery showed the landscape and building damages before and after the magnitude-7 earthquake hit Haiti in the beginning of 2010. This image was taken after the earthquake.

On April 20, 2010, the BP Deepwater Horizon drilling platform collapsed and sank in the Gulf of Mexico, causing one of the largest oil spills in history. One of the big dilemmas in responding to the oil spil is how to clean up the oil itself. One way currently under research is to use bacteria that naturally break down oil.

You may notice a green, red or brown film on your favorite boating or swimming area in the summer. This coloring could mean that the water is affected by harmful algal blooms. Harmful algal blooms are an accumulation of tiny organisms known as algae and can release harmful toxins into the environment. Pictured here is Binder Lake in Iowa covered in algal blooms.

USGS researchers discovered a new species of turtle. The Pearl River map turtle makes its home in the Pearl River of Louisiana and Mississippi.

Setting block net across an intertidal rivulet draining a hurricane-derived mudflat.  Net is retrieved at low tide to obtain an estimate of fish catch.  Fish density was found to be greater in waters draining natural tidal forests than in waters from mudflats formed as a result of landfall of a Category 5 hurricane on Cape Sable, Everglades National Park i

Sampling fish within the intertidal zone of a mangrove forest requires setting a block net at the interface between forest and river at high tide, then retrieving the net at low tide.  Here researchers await high tide to set the nets seen in the boat.
