Flow diagram of coal to coal-tar-pitch process
Coal tar is a byproduct of the coking, liquefaction, or gasification of coal. Coal-tar pitch is the residue that remains after the distillation of coal tar. Coal tar and coal-tar pitch are used in coal-tar-based sealcoat products, although use of coal-tar pitch is more common than use of coal tar. Both coal tar and coal-tar pitch are known human carcinogens.

Mapping Cape Cod National Seashore using unmanned aerial systems
The USGS conducted UAS flights to map the Nauset Marsh and Coast Guard Beach areas of Cape Cod National Seashore on Tuesday, March 1, 2016. These are the first authorized UAS flights in the northeast region of the national park system, and were performed under a research permit according to FAA and DOI regulations.

PAHs near pavement sealed or not sealed with coal-tar sealant
Concentrations of polycyclic aromatic hydrocarbons (PAHs) in settings near pavement sealed with coal-tar-based sealants were substantially higher than concentrations in settings where coal-tar sealant was not used.

Stony Coral Tissue Loss Disease in Biscayne National Park
The Florida Keys reefs have been experiencing a severe disease outbreak from 2014 to present called Stony Coral Tissue Loss Disease (SCTLD).

Transport pathways for PAHs from coal-tar-based sealcoat
Coal-tar-based sealcoat is a potent source of PAHs and related chemicals. Worn particles of coal-tar-based sealcoat are transported by rain, wind, tires, and even our feet from pavement to other environmental settings. Sealcoat product (A), after it dries, gradually abrades to a powder and becomes part of the dust on the pavement (B).

USGS-CVO crew digs out Mount St. Helens' Sep. Lobe monitoring station.
During the first few days of Mount St. Helen's earthquake swarm in March 2016, the September Lobe monitoring station (located on the 1980-86 dome) was buried in deep snow and not transmitting data.

June 27th lava flow and steepest descent paths near Pāhoa, Kīlauea
This small-scale map shows Kīlauea's June2th lava flow boundaries on March 25, 2016, in relation to the eastern part of the Island of Hawai‘i. The area of the flow field on February 20 is shown in pink, while widening and advancement of the flow field as mapped on March 25 is shown in red. Pu‘u ‘Ō‘ō lava flows erupted prior to June 27, 2014, are shown in gray.

Chesapeake Bay ospreys are healthy despite toxics in their fish diet
An adult osprey brings a fish to its nestlings at Poplar Island, Maryland. USGS researchers placed game cameras in some osprey nests to identify the types of fish that Chesapeake Bay ospreys are eating, then tested those fish species for toxic chemicals.
