Bruce Bernard (left) and Scott McBride (right) obtain water and sediment samples at Egmont Key which is about 1 mile west of the mouth of Tampa Bay in the Gulf of America. Samples were collected June 14, 2010 prior to the possible occurrence of oil contamination from the Deepwater Horizon's oil well.

A map showing North America's tropical-to-temperate transition zone. Red, orange, and yellow depict the more tropical zones, and blues depict the more temperate zones, based on to the coldest recorded temperature for each area between 1980 and 2009.

 Winter temperature extremes control the distributions of subtropical fishes. Common snook (Centropomus undecimalis), aggregate at a spring in northern Florida during winter. Snook are warm saltwater game fish, common in Florida, that have been moving further northward as extreme cold spells become less frequent and less intense.

In this NOAA satellite image from Sept. 15, 2020, Hurricane Sally approaches the U.S. Gulf Coast, Hurricane Paulettte creates storm waves far out in the Atlantic, and Tropical Storms Teddy and Vicky lie near the coast of Africa. Two tropical depressions are also developing; one of them is not visible in this image.

USGS coastal change experts predict that storm waves kicked up by the Category 1 hurricane are likely to cause some erosion at the base of the dunes along about 11 percent of coastal beaches between Florida and Virginia.

The U.S. Geological Survey has released a report on the potential duration of aftershocks of the 2020 Southwest Puerto Rico earthquake sequence (series) to guide public policy decisions, other actions, and help people stay safe and care for themselves and each other.

El Servicio Geológico de los EE. UU. ha publicado un informe sobre la duración potencial de las réplicas de la secuencia (serie) del terremoto del Suroeste de Puerto Rico en el 2020 que puede ser usado como guía en las decisiones de política pública, otras acciones y ayudar a las personas a mantenerse seguras y cuidarse a sí mismas y a los demás.
