Caption

CARD-FISH images of UCYN-A haptophyte symbiosis in the Bering Sea. The nitrogen fixing cyanobacteria UCYN-A2 are shown in red and the Haptophyte algae host are shown in blue and green. The bottom row are nanoSIMS results of the cells identified by CARD-FISH. The colors represent the 15N:14N ratio, warmer colors show higher enrichment of 15N, indicating they are fixing 15N2 gas.
