Seismograph information

The continental crust bears the scars of over 4 billion years of Earth history, and North America provides one of the most complete records of continental growth, modification, and breakup. EarthScope (www.earthscope.org), funded by the National Science Foundation, is a project for deep geoscientific exploration of the entire North American continent, and our Earth. The EarthScope Program provides a framework for broad, integrated studies across the Earth sciences, including research on fault properties and the earthquake process, strain transfer, magmatic and hydrous fluids in the crust and mantle, plate boundary processes, large-scale continental deformation, continental structure and evolution, and composition and structure of the deep Earth.

To gather data for these studies Earthscope installed seismometers in a grid array across the United States. One of the seismometers, EarthScope Station L61B, is located at the MacLeish Field Station. The three component broadband sensors continuously sense, record, and transmit ground motions from a wide range of seismic sources, including local and distant earthquakes, volcanic eruptions, and other natural and human-induced activities. You can see the output of this monitor on the web (EarthScope Station L61B). The station was installed in 2013.

Environmental Monitoring

To support research in the environmental sciences and to improve quantitative literacy among all students at Smith College, the Center supports an environmental monitoring program. Quantitative data on the environments around Smith are made available to faculty and students for use in courses and projects. Currently, most of these efforts are based at the MacLeish Field Station, and we see opportunities to grow this program to include Smith's campus and other areas.

Environmental monitoring at the Ada and Archibald MacLeish Field Station currently comprises measurement of meteorological variables and vegetation. Continuous measurements from atop an eighty-foot tower include atmospheric pressure, temperature, relative humidity, solar radiation, and wind speed and direction. These data are complemented by precipitation recorded by a heated tipping-bucket rain gauge at ground level. Additionally, three 20 x 50 m (0.1 ha) permanent vegetation plots were established in hemlock-dominated forests in 2009, and micrometeorological stations were added to these plots during the summer of 2010. Shorter-term monitoring efforts have included snow sampling, geochemical surveys of streamwater, and assessing the differences in throughfall chemistry and volume between deciduous and hemlock forest stands.
