A sampler was designed to observe detailed vertical gradients of dissolved gases in a shallow lake in winter; modified versions were used to examine horizontal gradients at the ice‐water interface and vertical gradients in the littoral of lakes in summer. A weighted cylinder, open at the top and sealed at the bottom, is lowered into the water deep enough that bottles then placed in it will be below the water surface. Water is siphoned into the bottles through tygon tubes with a self‐starting siphon. Repeated samples were obtained at air temperatures as low as −25C.
