Short summary

The Southern Ocean is a key sink of carbon dioxide (CO_{2), but efforts to study trends in and the variability of the sink have been hindered by the limited number of CO_{2 measurements in this region. Here we describe a set of new in situ continuous (minutely) atmospheric CO_{2 observations. We show that this new record better captures long-term changes and seasonality than traditional 2-weekly flask records. As such, this data set will provide key insights into the changing Southern Ocean sink.}}}
