Flood-inundation maps for Río Grande de Arecibo in and near Utuado Municipio, Puerto Rico, 2026 Flood-inundation maps for Río Grande de Arecibo in and near Utuado Municipio, Puerto Rico, 2026
The U.S. Geological Survey (USGS) created digital flood-inundation maps for a 3.4-mile reach of Río Grande de Arecibo in the municipality of Utuado Municipio, Puerto Rico. Water-surface profiles were computed for the stream reach by using a one-dimensional, steady-state, step-backwater model. This model was calibrated to the current (2026) stage-streamflow relation (rating curve number...
Shifting phenology in planktonic foraminifera in the Gulf of America (Mexico) with 21st century warming Shifting phenology in planktonic foraminifera in the Gulf of America (Mexico) with 21st century warming
We investigate trends in foraminiferal phenology using a 12-year (2008–2020), well-resolved (7 to 28-day resolution) time series of planktonic foraminiferal fluxes from a U.S. Geological Survey sediment trap in the northern Gulf of America (Gulf of Mexico; 27.5°N, 90.3°W). The total foraminiferal flux declined over this time. We used Horn-Morisita dissimilarity analysis, principal...
Effects of storm surge exceedance value on overwash and inundation forecasts Effects of storm surge exceedance value on overwash and inundation forecasts
Hurricane induced sediment transport and flooding can cause catastrophic damage to coastal communities. Forecasts test our understanding of the drivers of sediment transport and flooding, as well as quantify potential storm effects on coastlines. Real-time availability of forecasts allows emergency response and management decisions to be made with additional information. This study...

Decoding Harmful Algal Blooms: Unraveling the Mystery
Harmful algal blooms (HABs) are a significant environmental concern due to their potential effects on health, ecosystems, and economies. Algal toxins, which are toxic compounds produced by certain species of cyanobacteria and algae, are commonly linked to these blooms. It's important to note that algal toxins can still be present even when a bloom is not visible, highlighting the need for ongoing...
