probes and fluorescent in situ hybridization (FISH). Seawater sampled at 80 m depth
at 177 miles offshore of Moss Landing, California, USA. Bacteria are labeled with a
fluorescein (green) stain and Archaea are labeled with a CY-3 (red) stain. Scale bar, 5
μm. Separate images were overlaid in Adobe Photoshop.
