Heterosigma akashiwo in Bay
By sshukla@usgs.gov from All News. Published on Feb 04, 2026.
A new study by several scientists examines the environmental conditions that fueled a massive algal bloom in the San Francisco Bay. By analyzing water quality, circulation, and microscopic communities, the research helps explain how rare combinations of factors can drive major ecological events, including blooms of Heterosigma akashiwo, a species first identified in Japan.

Satellite Imagery Shows Beach Widening in Southern California Driven by Human Activity
By ppearsall@usgs.gov from All News. Published on Feb 02, 2026.
While many of California’s beaches have narrowed over time due to coastal erosion, new research from USGS and the University of California, Irvine shows that some beaches consistently defy this trend. In fact, the amount of beach growth outpaces the erosion in southern California—thanks largely to human intervention.
Yellowstone earthquakes that are related to ground deformation

Volcano Watch — When it rained rocks: tephra fall during Kīlauea’s episode 41
By kmulliken@usgs.gov from All News. Published on Jan 29, 2026.
Large lava fountains streamed from both the north and south vents reaching heights of at least 1475 feet (450 meters) during episode 41 of Kīlauea’s summit eruption on January 24, 2026. Strong updrafts coupled with light winds blowing to the east and north sent lava fragments from the fountains, called tephra, over much of the District of Puna and into South Hilo and the eastern edge of Kaʻū.
Photo & Video Chronology — January 27, 2026 — Tephra fall from Kīlauea episode 41
By kmulliken@usgs.gov from All News. Published on Jan 29, 2026.
During episode 41 on January 24, lava fountains from the north and south vents in Halemaʻumaʻu at the summit of Kīlauea reached up at least 450 m (1475 feet). Weak surface winds in combination with stronger upper-level winds blowing to the east and north resulted in widespread tephra fall in communities to the northeast and east within the Districts of Kaʻū, Puna, and South Hilo.

Episode 41 of lava fountaining at the summit of Kīlauea was active for 8 hours and 18 minutes on January 24, 2026. Weak surface winds in combination with stronger upper-level winds blowing to the east and north during episode 41 resulted in widespread tephra fall in communities to the north, east-northeast, and east of the eruptive vents (District of Puna on the Island of Hawaiʻi)
Finding and defending grassland cores using spatial covariance
By shouse@usgs.gov from All News. Published on Jan 27, 2026.
Grassland ecosystems continue to lose ecological integrity as woody plants invade and fragment habitat. This talk demonstrates how spatial covariance can more accurately flag grassland cores and edge conditions relevant to bird occupancy than tree‑cover metrics alone. The talk highlights management implications for defending cores and restoring contiguous habitat.
Florida’s Fading Coral Reefs Could Sharply Increase Coastal Flood Risk
By ppearsall@usgs.gov from All News. Published on Jan 26, 2026.
Coral reefs do more than support vibrant marine ecosystems—they also act as natural breakwaters, protecting coastlines from storm-driven waves. New USGS-led research shows that as Florida’s coral reefs continue to degrade, the loss of this natural protection could dramatically increase flooding risk for coastal communities in southeast Florida.

Biophysical controls on sediment erodibility in San Francisco Bay
By ppearsall@usgs.gov from All News. Published on Jan 23, 2026.
The erodibility of bed sediment in estuaries can shape everything from water clarity to habitat quality, and influences the magnitude of sediment transport. While scientists largely understand how bed sediments in sandy environments erode, less attention has focused on muddy sediments in estuaries. New research from USGS shows that waves matter—but so do the animals living in the mud.
Volcano Watch — What do small earthquakes beneath Kīlauea summit mean for the ongoing eruption?
By kmulliken@usgs.gov from All News. Published on Jan 22, 2026.
“Volcano Watch” articles over the past two weeks have described past episodic lava fountaining eruptions at Kīlauea Iki (1959) and Maunaulu (1969). Next week, we will continue this series with a summary of the most recent past episodic eruption at Kīlauea. Why? Because past eruptions can give us clues as to how the ongoing episodic eruption in Halemaʻumaʻu might progress or change.
