Flux towers track CO2 exchange between forests and atmosphere

Determining exchange rates of carbon dioxide between the earth’s forests and the atmosphere is turbulent business. Wind above forest canopies swirls as vortexes of air enter and exit stands of trees.  Across the globe, towers stand among the landscape, with sensors monitoring these eddies for carbon dioxide, water vapor and other gasses.  These so-called “flux towers” collect data on carbon dioxide exchange rates between the earth and atmosphere. Information gathered plays into the debate on the measurable effects of climate change. Carbon dioxide flows between the earth, atmosphere and ocean in an attempt to reach equilibrium. As automobiles and energy production facilities burn fossil fuels, more carbon dioxide joins to the mix.

Government Officials Ignore Health Risks Associated with E. coli in Boulder Creek

Since 2003 harmful bacteria Escherichia coli (E. coli) levels have created a health risk to recreational users in Boulder Creek. Boulder Creek has been designated as an impaired stream and is not meeting an EPA health-based water quality standard. Concentrations of E. coli increase from the mouth of Boulder Canyon to the University of Colorado-Boulder and beyond based upon data collected by the City of Boulder according to information published by the CU Independent and the Boulder Camera . EM spoke to environmental engineer Art Hirsch of the Boulder Waterkeeper , who is advocating for greater accountability from all entities that own property abutting the stream. “E.

New Monitoring Site for Ocean Acidification in American Samoa

The National Oceanic and Atmospheric Administration (NOAA) and the Pacific Islands Ocean Observing System (PacIOOS) at the University of  Hawaiʻi at Māno a , in collaboration with other partners, recently deployed a new ocean acidification (OA) monitoring site in Fagatele Bay National Marine Sanctuary , American Samoa. Derek Manzello , a coral ecologist with NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) in Florida, is the lead PI of ACCRETE: the Acidification, Climate and Coral Reef Ecosystems Team at AOML. Dr. Manzello connected with EM about the deployment. “ACCRETE encompasses multiple projects that all aim to better understand the response of coral reef ecosystems to climate change and/or ocean acidification,” explains Dr.
