Dr. Mark Buckley of the USGS St. Petersburg Coastal and Marine Science Center holds a new Sofar Smart Mooring and Spotter Buoy that will be used to deliver high-fidelity, real-time wave, water level, and wind data. These data will be used to validate and improve the USGS/NOAA Total Water Level and Coastal Change Forecast, which provides real-time forecasts of water levels and coastal change along nearly 3,000 miles of the U.S. Gulf and Atlantic coasts.

A camera is attached to the kite and taken up and down the beach to take a bunch of pictures used to create a digital elevation model with structure-from-motion techniques.

In August of 2020, the enormous CZU wildfire complex consumed over 85,000 acres in San Mateo and Santa Cruz Counties, leaving scarred landscapes in the hilly region. Runoff from large rainstorms in the winter months carry contaminants from the soils within these burned-out forests. Forest fires and the fire retardants used to help control and extinguish them introduce chemicals into watersheds that can harm wildlife and contaminate drinking water. Research geologist Renee Takesue, of the USGS Pacific Coastal and Marine Science Center, samples stream sediment in the lower parts of burned watersheds to measure concentrations of several kinds of contaminants after the major storm runoff in late January of 2021. Our team hopes to compare these with samples taken from the same watersheds after the fire. Samples must be collected before too much time has elapsed since the wildfires, before post-fire storms wash the burned material downstream.

The atmospheric river, a narrow, powerful track of water vapor that can deliver tremendous volumes of rain, hit the central California coast and stalled there between January 26 and 28, 2021 — with catastrophic consequences. The area around Rat Creek, about 20 miles south of Big Sur's town center, received more than 8 inches of rain during a 2-day period, according to the National Weather Service. Rainwater washed dead trees, ash, mud, and rock downslope from the nearby watershed, scorched by the Dolan Fire in Los Padres National Forest in the fall of 2020. Drain pipes that run below Highway 1 were rapidly clogged with the debris and were eventually overwhelmed. The roadway was no match for the overflowing culverts, resulting in a massive collapse of the rocky cliff. On January 29th, a USGS reconnaissance flight snapped this dramatic photo above the Rat Creek drainage showing the debris flow.

On May 20, 2017, this section of the Big Sur coastline experienced a huge landslide that wiped out scenic coastal Highway 1. By July 2018 the roadway was reopened. USGS scientists from the Pacific Coastal and Marine Science Center and the Geology, Minerals, Energy, and Geophysics Science Center continue to monitor this section of the coastline, in collaboration with the California Department of Transportation. This photo was taken January 29, 2021.
