1999 Projects: Midwater researchThe midwater region, below the photic zone but above the benthic boundary layer, is the largest living space on Earth. MBARI is one of the few institutions with the tools to study this fascinating realm inhabited mostly by gelatinous animals that feed on particulate matter generated in the overlying photic zone. In 1999 we will continue quantitative measurements of the vertical distribution, abundance, and seasonal variations of three key types of midwater animals: larvaceans, siphonophores, and hydromedusae. We will also continue to collect samples of these animals for studies on their life cycles and feeding behavior. These studies will be closely coupled with RNA analyses to determine phylogenetic relationships among the various species. Genetic typing is particularly useful for ascertaining the evolutionary relationships of midwater organisms, for which no fossil record exists.For 1999 midwater research is grouped under two projects:
