The Oysters of Chicopit: Status of the Oyster Population in Chicopit Bay before, during, and after the Construction of the Mile Point Project

Chicopit Bay, part of the Timucuan Ecological and Historic Preserve in Florida, is a small embayment at the intersection of San Pablo Creek (part of the Intercoastal Waterway) and the St. Johns River. Home to a number of small oyster beds, this area is now being dredged to help eliminate cross currents from the main shipping channel of the St. Johns. WARC researchers collect baseline...

A desmid alga is bright red and green photographed in UV light
December 31, 2017

This single-celled alga is a natural ornament

It looks like a holiday ornament, but this lovely object is a single-celled freshwater alga from the desmid family, found in the marshes of Florida’s Arthur R. Marshall Loxahatchee National Wildlife Refuge. USGS biologist Barry Rosen photographed it at 200x magnification using ultraviolent light and a fluorescence microscope. Desmids range in size from under 10 microns—

Ultraviolet light gives desmid alga cell a bright red glow


Illuminated with ultraviolet light, this living desmid cell has a bright red chloroplast. USGS biologist Barry H. Rosen, an expert on aquatic microorganisms, takes exquisite microscopic photos as part of his study of these single-celled green algae, which he has collected in a nearly pristine area of the northern Everglades. This cell got smooshed (the technical

USGS Hurricane Preparedness

Before a hurricane, USGS Scientists undertake a data collection effort of a grand scale. They install a temporary mobile network of sensors along the coasts to collect additional data on the intensity of storm surge, one of the most dangerous elements of a hurricane. This effort provides critical information that allows various USGS partners and emergency responders to

Image of the Week - Irma Churns Up Sediment in the Florida Keys

Hurricane Irma churned up sediment around the Florida keys as shown by these Landsat images.

At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.

Irma Churns Up Sediment in the Florida Keys

Hurricane Irma crossed the Florida Keys the morning of September 10, 2017, as a Category 4 hurricane with winds of 130 miles per hour. Besides damage done to structures on the islands, the storm also stirred the waters.

A natural marvel in a single cell

This single-celled freshwater algae wasa collected as part of the first-ever study of the green algae family called desmids in Florida’s Loxahatchee National Wildlife Refuge, in the northern Everglades. USGS biologist Barry H. Rosen, an expert on freshwater algae who leads the study, used a technique called differential interference microscopy to highlight the relief of

A glimpse of the microbial world's hidden beauty

To collect, identify and document these single-celled algae called desmids, USGS biologist Barry H. Rosen has traveled by airboat into the interior of Florida’s Loxahatchee National Wildlife Refuge, where decaying marsh grasses created a mosaic of peat soils and the soft, slightly acidic water where desmids grow. Rosen thinks the area may have some of the world’s greatest
