Ecological dynamics in the subarctic Pacific, a possibly iron-limited ecosystem

Creator:

Miller, Charles B., Frost, Bruce W., Wheeler, Patricia A., Landry, Michael R., Welschmeyer, Nicholas, and Powell, Thomas M.

Abstract:

It has been suggested that production in offshore waters of the subarctic Pacific is limited by availability of dissolved Fe. Although that is not yet adequately established, the functional consequences of the limitation (if it exists) can be characterized from the results of the Subarctic Pacific Ecosystem Research (SUPER) program....

Impacts of microbial chemical interactions on marine plankton physiology

Creator:

Moore, Eric R.

Abstract:

The bioavailability of chemical compounds in the marine environment fundamentally influences the growth and physiology of microorganisms. Organic and inorganic chemicals that are produced by some marine plankton can be consumed by other plankton for energy production, growth, or to initiate essential physiological processes. Cultures of the diatom Thalassiosira pseudonana,...

Single-Cell Genomics of Uncultivated Marine Bacteria

Creator:

Landry, Zachary

Abstract:

Historically, the difficulty of obtaining pure cultures of abundant marine microbial plankton has an obstacle to reconstructing the underlying mechanisms of biogeochemistry in the ocean. While a number of dominant marine species from the ocean surface have been cultured, the dominant microbial plankton of the dark ocean proved far more...
