As part of the Remote Sensing of Coastal Change and Florence Supplemental projects we have been developing novel workflows for repeat-mapping of coastal environments at order decimeter resolution over up to hundreds of kilometers in a single day, using Structure-from-Motion photogrammetry or SfM, from crewed aerial platforms.

Hinkley Valley, in the central to western Mojave Desert of southeastern California, has a long historical record owing to its position as a crossroads for rail and road traffic and its position adjacent to the Mojave River.

Katy O’Donnell onboard the RV Landsteiner during a high-resolution water quality mapping survey. The boat is equipped with a flow-through system that pumps water onto the boat while underway and directs sample water to a multiparameter water quality sonde, thermosalinograph, fluorometers, nitrate and ammonium analyzers.

The western fissure in Halemaʻumaʻu wall remains active. Glowing vents and a prominent spatter cone are visible in this photo, which shows some spattering at the vent. This view looks steeply down from Kīlauea's west caldera rim, and the lava lake surface is visible in the background. USGS photo by B. Carr on 12/31/2020.

Diagram of the SQUID-5 towed surface vehicle and the waterproof camera housings with labeled components. The camera mounting mechanism aligns the camera axially with the dome and allows the camera to be adjusted fore and aft to accommodate various lens types and enable alignment with the glass port radius of curvature for minimal distortion.
