Unified Interior Regions

Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.

USGS scientists installed a rapid deployment gauge Feb. 14 near Goffstown

USGS field crews are deploying storm-tide and wave sensors today from Maine to Delaware to track and study a Nor’easter forecasted to begin tomorrow.

Significant flooding along the coast of Massachusetts occurred Thursday, January 4, 2018, caused by a powerful blizzard.  Peak storm surge of approximately 3.00 feet occurred at the astro high tide; and, according to the National Weather Service, is the highest since records began at the Boston tide station in 1921. 

A carbonatite here, a glacial moraine there, a zig-zagging fault or two, even a behemoth of a batholith. The geology of the 50 States is an enormous patchwork of varied forms, beautiful in their variance but challenging to present as a single map.

A high-tech buoy that monitors water quality in real time was just installed in one of New England’s most popular lakes, where in the future it will help with determining when swimmers should and shouldn’t be in the water. 

New USGS models help predict storm effects on beaches

As the 2016 hurricane season opens, weather forecasters, emergency managers and coastal residents have access to tools developed by the U.S. Geological Survey that predict, more precisely than ever, where beach erosion and beachfront flooding will take place during hurricanes and other storms.

First-of-its-kind survey shows that algal toxins are found nationwide

Much of the coast from Maine to Virginia is more likely to change than to simply drown in response to rising seas during the next 70 years or so, according to a new study led by the U.S. Geological Survey.

A newly published, three-volume “Remote Sensing Handbook” is a comprehensive coverage of all remote sensing topics written by over 300 leading global experts.

With the release of new US Topo maps for Illinois and South Dakota, the USGS has completed the second, three-year cycle of revising and updating electronic US Topo quadrangles. This means that since late 2009, the USGS has published nearly every map in the conterminous U.S., twice.
