USGS scientists collect core samples from estuaries, lakes, coasts, and marine environments to study a range of physical and chemical properties preserved in sediment or coral over time. They process and analyze these core samples at the Pacific Coastal and Marine Science Center’s Sediment Core Lab.

Image of the Week: Tulare Basin Refills
A winter of heavy rain causes flooding in California's Tulare Basin, threatening cropland. The basin was once the site of a large lake that appeared naturally every winter as rainfall and snowmelt from the nearby Sierra Nevada mountain range flowed down and filled the basin. It was even known as the largest lake west of the Mississippi River.

Tracking Coastal Change with Photogrammetry (AD)
Monitoring coastal changes is important for the millions of people that live along coasts in the United States, particularly as climate change hastens coastal erosion by raising sea levels and fueling powerful storms.

Sediment Transport in San Francisco Bay (AD)
The Sacramento and San Joaquin Rivers deliver half the amount of sediment they did 50 years ago to San Francisco Bay. Just as sea-level rise is accelerating, the demand for sediment is growing.

Image of the Week - Caldor Fire Expands Toward Lake Tahoe
The Caldor fire in California started on August 14, 2021 and quickly spread in high winds.
The fire continues to expand toward the Lake Tahoe area as residents evacuate.
This image was captured on August 21, the 8th day.
Landsat 8's near infrared and shortwave infrared bands reveal active fire, burn scars, and smoke.

Image of the Week - Dixie Fire Ravages Northern California
The Dixie Fire has become the largest single fire in California's recorded history. State fire officials don't list it at the top, however. The record is held by the massive August Complex fire of 2020 which burned over one million acres. The term "complex" is used when multiple fires in the same area ignite separately.

Ferromanganese Nodules—2021 North Atlantic Stepping Stones Exped. (AD)
During a recent dive on the New England Seamount chain off the North Atlantic coast, researchers aboard the NOAA Ocean Exploration Expedition, North Atlantic Stepping Stones, discovered a marine geological feature known as a ferromanganese (Fe-Mn) nodule field in the saddle between two peaks of Gosnold Seamount.
