new image gallery: fieldwork at Twitchell

I've posted some shots from a recent foray to Twitchell Island to gather soil cores, water samples, and do some recon for our new carbon capture project. Twitchell Island is in the Delta; it is a ~1,000-ha property, 2 metres below sea level, bounded on the north by Seven Mile Slough, on the east and south by the San Joaquin River, and on the west by Three Mile Slough. It is the site of an experiment being conducted by the U.S. Geological Survey to study whether growing tules and cattails on the sinking islands of the Sacramento Delta can reverse the soil loss caused by wind, rain and farming. The soil under the 15-acre site has risen 1 to 2 feet since the project started in 1996.
