Science advances: the marine carbon cycle

Posted 3 years 4 months ago

The amount of dissolved carbon in the world's oceans is roughly equivalent, and likely greater, than atmospheric concentrations of CO2. Some of it gets semi-permanently sequestered, some gets released up into the atmospheric in a process that has been in place for millions of years. But with the global carbon picture changing, understanding the details of these processes has become more urgent: the slightest changes in ocean temperature or acidification (not hypothetical: we know these conditions are in flux) could usher in major changes in the relationship between the carbon in...

Robinson Fall Commencement Address

Anthropocene lecture: repairing the world

Posted 3 years 5 months ago

The final event in this fall's very successful Anthropocene Lecture Series takes place tonight at 7 p.m in the Chapel. No scientific investigation can be complete without the inclusion of a moral perspective and tonight's lecture looks at the ways theology and science can work together:

The physical sciences tell us the what and the how regarding the condition of the earth, but the why question -- why should we engage in helping to repair our world -- is a matter seriously addressed by people of faith.  There are also many people of no faith equally concerned and willing simply...

The 'Anthro' in Anthropcene

Posted 3 years 6 months ago

Who is the 'Anthro' in Anthropocene? A very good question, and professor of philosophy and women's studies Chris J. Cuomo provides the answer Thursday at the Chapel in this week's installement of the Anthropocene Lecture Series:

The term “anthropocene” has gained enormous popularity among scientists who believe that we are currently in a global geological era that is distinguished by the extensive and lasting impacts that “human” activities (i.e. fossil fuel combustion, deforestation, pollution, etc.) are having on all of Earth’s vital systems. But should the practices, institutions...

Carbon Sequestration in Salt Marshes

Posted 3 years 6 months ago

The importance of the world's rainforests, and to some extent the mangroves, as storage sinks for atmospheric are carbon well-known. But salt marshes, too, are extraordinarily efficient mechanism for photosynthesis and the production of biomass that work together to sequester carbon at a high rate. So disappearing wetlands along the coast present much more peril than loss against storm surge, which itself plays significant part in their role in an ecosystem.

Now, Deepak Mishra, associate professor in the department of geography, has developed tools and techniques to map carbon...
