M.O. Title: An Oligotrophic Oceanic Microbial Observatory

Location:Northwestern Sargasso Sea- off Bermuda

Created by George Rice, Montana State University

Deploying a conductivity, temperature, depth (CTD) rosette profiling package in the Northwestern Sargasso Sea off of Bermuda. The CTD is used to collect discrete water samples at specific depths throughout the water column (0 - 2000 m) of this research site. Each bottle is independently triggered for collection from the bridge of the R.V. Weatherbird II. Picture provided by C. Carlson (Oceanic Microbial Observatory)

This project focuses geographically on the Bermuda Atlantic Time-series Study (BATS) site. This site is one of the longest time-series studies of oceanographic conditions on the planet and for the past decade has been a test bed for the development of advanced molecular techniques developed to measure microbial diversity. The rich data set from BATS provides important physical, chemical and biological information that is used by the microbial observatory to understand how ocean conditions affect the planktonic microbial communities. The Oceanic Microbial Observatory applies a new high throughput cultivation technology, developed at Oregon State University, to identify, count, and cultivate major oceanic microbial groups that have not previously been cultured. Technologies are also employed to characterize the quality and quantity of organic substrate utilization by these microorganisms.

Project Goals:

An overreaching goal of the Oceanic Microbial Observatory is to better understand the role of the ocean's smallest inhabitants, Bacteria and Viruses, in the context of larger oceanographic processes. This objective is being reached by:
