This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Viruses are now unarguably considered essential components of marine ecosystems with regard to their natural abundance and their ecological implications. The interaction of viruses with microaggregates is, however, poorly documented despite the critical implications of microaggregates for the ocean biogeochemistry and the marine optical properties. Thus, the main goal of this project is to shed light on the interactions between viruses and microaggregates. One of the major studies of this project focuses on the impact of viral lysis on the dynamics of microaggregates. This study involves the use of virus  host model systems isolated from the SIO-pier. The expected results will provide novel insights into our understanding of viral ecology and to a larger extend into the functioning of the ocean.
