In foreground, red-weathering rocks are Hue Shale (oil-prone source rock with is present throughout 1002 Area) and dark gray rocks are Kemik Sandstone (lateral equivalent to Thomson sandstone, main reservoir in Pt. Thomson field).

Scientist from the Florence Bascom Geoscience Center first sampled four islands in Florida Bay, Everglades National Park, in April 2014 to collect cores to study sea level rise and storm history in the region.  In September 2017, Hurricane Irma (a category 4 storm at landfall in the Florida Keys) passed just to the west of our field sites.  The western-most of the four

Sea-Level Rise, Extreme Water Levels, and Coastal Erosion ... How bad could it possibly be?

By Sean Vitousek, USGS Research Oceanographer

• Sea-level rise represents an unprecedented civil engineering challenge.
• Small amounts of sea-level rise can disproportionately increase the frequency

The World's Water - Distribution of Earth's Water

The Earth is a watery place. But just how much water exists on, in, and above our planet? About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent

(A) Underneath the β-layer of the epidermis is an accumulation of hypereosinophilic necrotic debris. The remaining epidermis is extensively ulcerated. Heterophils and macrophages infiltrate the underlying dermis. Skin, PAS. (B) Necrotic debris is found above the β-layer of the outer generation (BO) and between the BO and the β-layer of inner generation (BI).

Wildfires burned across Lebanon in mid-October 2019. A pair of images taken just 10 days apart by the European Space Agency's Sentinel-2A satellite show the burn scar from one of the larger wildfires.

Black Racer snake (A) The epidermis over much of the body, but cranially pronounced, has multifocal to coalescing dull white to pale gray foci. (B) Multiple scales around the head are thickened and roughened. (C) Ventrally, there are multiple dull white to grey foci of up to 8 mm size, occasionally with central indentations.

The Natural Water Cycle

Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over
