A view looking north into Halema‘uma‘u, at Kīlauea's summit, on September 24, 2021, seen during a brief clear spell between passing rain clouds. There has been no significant change in the surface elevation of the solidified crust of the lava lake since the eruption paused in late May 2021.

Tule white-fronted geese get ready to land at Summer Lake Wildlife Area in Oregon. The geese turn upside down and sideways to drop altitude quickly to land, a behavior known as "whiffling" or "maple leafing."

Two high-resolution, digital cameras were mounted on towers overlooking the beach, dunes, and instrument arrays in the Outer Banks of North Carolina on September 18, 2021, as part of the DUring Nea

Researchers from the USGS and North Carolina Universites set up their equipment on installed poles stretching from the dune to the surf zone.

To install instruments offshore professional divers were hired to work alongside USGS personnel. Here, long segments of pipe are jetted into the seafloor to which instruments will be attached to measure offshore oceanographic conditions.

USGS researcher Jenna Brown takes a measurement with a real time kinematic GPS receiver, this will give her an accurate position and height of the aluminum pole beneath it, which will have mutliple instruments attached to it to measure water flow and elevation changes.

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.

USGS scientists mounted this high-resolution digital camera on an observation tower in the dune at the U.S. Army Corps of Engineers Field Research Facility near Kitty Hawk, North Carolina. The camera overlooks the beach, dune, and an instrument array, and collects images throughout calm and storm conditions.

Metal poles and equipment will installed on the beach and in the surf zone near the Army Corps of Engineers Field Research Facility pier near Kitty Hawk, North Carolina. The poles extend about 5 feet above the ground or seabed, to support instruments that continuously measure wave heights, water levels, and currents using acoustics.
