The
Oceanic Microbial Observatory draws upon and contributes to several data
sets. The BATS biogeochemical database, the Bermuda Testbed Mooring (BTM)
and the Bermuda Bio-optics programs provide a rich contextual framework
in which we set our microbial observatory. These are public data sets and
can be reached by the following links. |

In addition to the microbial
time-series data collected through our microbial observatory, we also
perform a variety of experimental based projects designed to investigate
how factors such as nutrient limitation and mixing affect community structure
and remineralization of dissolved organic matter.

High throughput culturing technology,
developed by S. Giovannoni, is an approach used to isolate microbes from
seawater. The advantage of this approach is that it can successfully isolate
and identify organisms that can then in turn be cultured. This procedure
has been successful in bringing several organisms previously considered
"unculturable", including SAR
11, into cutlure. Below is a list of strains isolated from our Oceanic
Microbial Observatory.

BATS site throughout the BATS Time-series record. Note the subsurface pulses
of prokaryotes at depth. To learn more click here. |

This
panel shows electropherograms of community structure shifts in mixing experiments.
Here we tested the affects of mixing microbial populations of different
depth horizons with naturally occurring organic substrates collected from
the surface 10 m. Click here for
