Project Overview

The National Geodetic Survey (NGS), an office of NOAA’s National Ocean Service, manages a network of Continuously Operating Reference Stations (CORS) that provide Global Navigation Satellite System (GNSS) data in support of positioning, meteorology, space weather, and geophysical applications throughout the United States, its territories, and several foreign countries (ref: CORS website).

In September, UNAVCO installed a new CORS site in Seward, Alaska, as part of ongoing UNAVCO support of the CORS network. Data downloading and distribution is handled by CORS.

UNAVCO supports CORS installations and maintenance around the world. Future installations include a station in Nome, Alaska.

Significance

Seward, Alaska lies on Alaska’s southern coast, in an area susceptible to megathrust earthquakes and their accompanying tsunamis. Seward’s port was devastated by the tsunami generated by the magnitide 9.2 Great Alaska Earthquake in 1964, and continues to be a major tourist destination due to its dramatic setting and rich sea life. The CORS station in Seward is a multipurpose site serving surveyors, GIS users, engineers, scientists, and the public at large.
