Warning buoy
A buoy warning of the under-bay sewage treatment plant pipeline appears to guide the AUV on its course; confirming that the AUV’s position is accurate. The AUV uses a differential global positioning system (GPS) receiver and bottom-tracking Doppler velocimetry log (DVL) to maintain position.

Wastewater impacts
The AUV travels along the under-bay section of the Bergen Point Sewage Treatment Plant outfall pipe in Babylon, NY. The goal is to see if changes in surrounding water-quality suggest potential leaks in the aging infrastructure.

Kīlauea's summit lava lake puts on a good show today
In concert with inflationary tilt, the level of Kīlauea Volcano's summit lava lake rose over the past day and was measured at 28 m (92 ft) below the vent rim this morning.

Defoliated nonnative tamarisk with native cottonwood trees
Nonnative tamarisk can form mixed stands with native trees, such as cottonwoods, and other nonnative trees, such as Russian olive.

Mapping the Bay
This autonomous instrument reduces the time and manpower traditionally needed for manned-boat surveys. Because geologic, biologic, hydraulic, and chemical data are collected simultaneously; the datasets allow for a systems-based approach to analysis.

Nonnative tamarisk is fire resistant
Nonnative tamarisk is resistant to wildfire, in part due to its abilty to resprout from the its roots.

Three Gorges Dam Brings Power, Concerns to Central China
Images from Landsat 5 in 1993 and Landsat 8 in 2016 show how the Yangtze river transformed after the completion of the largest hydroelectric power plant in the world in 2012.

Where is the AUV?
If the vehicle becomes stuck or disabled at depth, a hydrophone can be used to locate the submerged instrument. When at the surface, the AUV can send its retrieval location to a web server or cell phone.

Off on a mission
The AUV navigates to its starting position before diving to a fixed distance off the seabed to measure dissolved oxygen concentrations in the Great South Bay, Long Island, NY. The goal is to document the spatial extent of low dissolved oxygen concentrations, or hypoxia, to identify the best habitat for juvenile hard clam survival.

Aug. 6 explosive event at Kīlauea's summit
On August 6, a rockfall from the steep walls of Overlook crater, which contains Kīlauea Volcano's summit lava lake, triggered an explosive event that deposited spatter (molten lava) and solid rock fragments on the rim of Halema‘uma‘u Crater. That event was just the latest in a series of explosions that began in 2008.
