Oceanic plankton have been hypothesized to occur in micropatches (<10 meters) that can have a large impact on marine ecosystem dynamics. Towed video microscopy was used to unobtrusively determine distributions of oceanic plankton over a continuum of scales from microns to hundreds of meters. Distinct, taxa-specific aggregations measuring less than 20… (More)
Plankton form the base of the food chain in the ocean and are fundamental to marine ecosystem dynamics. The rapid mapping of plankton abundance together with taxonomic and size composition is very important for ocean environmental research, but difficult or impossible to accomplish using traditional techniques. In this paper, we present a new pattern… (More)
Pelagic marine ecosystems are characterized by variability in biotic and abiotic components across a continuum of time and space scales from microns to thousands of kilometers (Haury et al. 1978). Present monitoring of these ecosystems is done primarily by large-scale ocean surveys that use net and bottle sampling to collect specimens for quantifying… (More)
Polycystine Radiolaria are one of the most conspicuous zooplankton taxa inhabiting the oceanic waters of the tropics and subtropics. Radiolaria are single-celled, eukaryotic organisms that are exclusively marine and, almost exclusively oceanic in their distributions. The unique morphologies and complex life histories of these organisms have captured the… (More)
