An alternative to uncrewed aerial systems (UAS; commonly known as 'drones'), U.S. Geological Survey (USGS) scientists use helikites equipped with cameras to collect imagery of the coastline. The pictures collected by these helium-powered kite-balloons are used to create a 3D digital elevation map of the beach.

Coastal communities, especially those on barrier islands, are vulnerable to processes of coastal change. The DUring Nearshore Event eXperiment (DUNEX) project is a multi-agency, a

The US Army Corps of Engineers Field Research Facility in Duck, NC has set up a variety of sensors and arrays on the beach to measure oceanographic paramters for DUNEX

To survey the bathymetry off of the Pea Island DUNEX site WHOI investigator Peter Traykovski prepares to run into the surf with the ASV nicknamed "Robo Turtle" while USGS investigator Chris Sherwood handles the remote controller.

Hurricane Ida made landfall as a Category 4 hurricane in Louisiana, and brought widespread precipitation and flooding along its path and up the northeastern coast of U.S. in the following week.

No changes were observed at Kīlauea's summit during a brief field visit on September 3, 2021. Sunny weather made for spectacular views, though strong winds were blowing. The solidified crust of the lava lake within Halema‘uma‘u—which was active from December 2020 to May 2021—is visible in the lower center of this image. USGS photo by K. Mulliken.

View from a temporary webcam, which is located just southwest of Kīlauea summit caldera, and looks south over the area of the August 2021 intrusion. The dark lava flow on the left of image (mid-ground) is where the 1982 lava flow spilled out of the south caldera.

The USGS Active Groundwater Level Network includes about 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months. The animation shows snapshots of water-level statistics in the network during August 2021.

HVO technician Steven Fuke checks the solar panel at station HRPKE while conducting station maintenance on September 1. HVO remote monitoring stations are powered via solar panels and a suite of batteries.

Station HRPKE is located southwest of Kīlauea's summit, in the upper Southwest Rift Zone region, within Hawai‘i Volcanoes National Park. The station measures sulfur dioxide (SO₂) concentrations in the air, as well as local meteorological data such as wind speed, wind direction, and rainfall.
