All experiments were performed with seawater from a 5-m depth, unless otherwise noted. Seawater was unfiltered unless otherwise specified. TdR, thymidine incorporation; Leu, leucine incorporation; ND, not determined. *, the rate of FLV tracer disappearance was higher than the rate of disappearance of unstained virus particles.
