The Carbon Collection of Inland Waters

The study of carbon in lakes is not new to SIL. Reports of carbon dioxide emission to the atmosphere from the Caspian Sea, of intense hydrogenetrophic methanogenesis in lake sediments, or of incredibly high CO2 partial pressures (>600,000 matm) in the bottom waters of L. Kivu all sound like modern limnological forays. Yet, these discoveries were all published in SIL journals in the 1930s (respectively, Brujewicz 1937, Kusnetzow 1935 and Damas 1937)!  It is a humbling exercise to look at past literature and discover that what you thought was cutting edge research was already studied decades before you were born. History aside, “carbocentric” limnology has enjoyed a remarkable renaissance over the last 10 years and SIL journals have remained at the forefront of it. This collection of carbon papers published in Inland Waters illustrates that what has changed is not the subject itself, but rather the scope of inquiry (continental to global), the diversity of delivery pathways and how they differ in different aquatic systems (streams, rivers, lakes and reservoirs). Enjoy the read!
