Noa Randall and Rachel Allen are installing an optical turbidity sensor on the mudflats in Wellfleet harbor, to pair with the altimeter run by the Center for Coastal Studies.  The Herring River, which drains into Wellfleet Harbor, is slated to have its 100-yo dam removed in the next 6 months, with the potential to dramatically increase the sediment load and sus

The USGS Puerto Rico Landslide Susceptibility Map provides an interactive tool to assess landslide risk in Puerto Rico from low susceptibility to extremely high.

In collaboration with the National Park Service, Woods Hole Oceanographic Institution, and the Vesta Corporation, the Environmental Geosciences group researched a new approach to climate change mitigation. The team led an experiment at the Herring River site as a first examination.

Aerial image of eruption in Halemaʻumaʻu at Kīlauea Volcano's summit taken during an overflight at approximately 7:30 a.m. HST on September 30, 2021. The eruption is generating a vigorous plume of volcanic gas, including sulfur dioxide, being transported downwind.

Aerial image of eruption in Halemaʻumaʻu at Kīlauea Volcano's summit taken during an overflight at approximately 7:30 a.m. HST on September 30, 2021. In this image, multiple active fountaining sources are visible in the central and western portions of Halemaʻumaʻu.

Aerial image of eruption in Halemaʻumaʻu at Kīlauea Volcano's summit taken during an overflight at approximately 7:30 a.m. HST on September 30, 2021. Lava continues to erupt from multiple vents along the floor and western wall of Halemaʻumaʻu crater. As of this afternoon all lava activity is confined within Halemaʻumaʻu Crater.
