Abstract Details (PID = P205)
Title:Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) Program (P205)
Description:Anthropogenic carbon dioxide (CO2), produced primarily by burning fossil fuels, is the one of the leading causes of climate change often referred to as global warming. Fortunately, the current atmospheric CO2 concentrations are only about half what they would otherwise be because the oceans are currently absorbing huge quantities. Both numerical models and existing data indicate that much of the oceanic uptake of CO2 occurs at high latitudes - almost exclusively in the Southern Ocean around Antarctica. Up until the beginning of the SOCCOM program almost all of the Southern Ocean seawater measurements of CO2 were taken during the local summer. In the local winter much of the area is either inaccessible due to ice coverage or simply too nasty/dangerous for routine oceanographic observations from research vessels. Four years ago the National Science Foundation funded the SOCCOM program to provide a wintertime upper ocean data set that would allow us to estimate CO2 concentrations and fluxes both in and under the ice. The measurements are being made by a collection of autonomous floats that are equipped with biogeochemical sensors. The floats are deployed during the summer, but are "smart" enough to operate year-around. The measurement list includes, temperature, salinity, dissolved oxygen, inorganic nitrate, pH, cholorphyll and particle density. When deployed the float sinks to 1000m (3280 feet) and then drifts with the current for 10 days in "sleep" mode. Then it sinks to 2000m (6562 feet) and subsequently measures all of the properties as it rises to the surface. Once at the surface the collected data are relayed ashore via satellite and are immediately (3-5 days) available for use. We encourage primary and secondary schools/classes to "adopt" these floats and we make the data available to the students at the same time as anyone else. Use of these data are up to individual teachers, but applications include geography, writing skills, graphing techniques (both simple and advanced), and biological, chemical and/or physical ocean processes. One goal of our outreach program is to have at least one SOCCOM float adopted in each state.
