Changing concentrations of CO, CH₄, C₅H₈, CH₃Br, CH₃I, and dimethyl sulfide during the Southern Ocean Iron Enrichment Experiments

Creator:: Wingenter, Oliver W., Haase, Karl B., Strutton, Peter, Friederich, Gernot, Meinardi, Simone, Blake, Donald R., and Rowland, F. Sherwood
Abstract:: Oceanic iron (Fe) fertilization experiments have advanced the understanding of how Fe regulates biological productivity and air–sea carbon dioxide (CO₂) exchange. However, little is known about the production and consumption of halocarbons and other gases as a result of Fe addition. Besides metabolizing inorganic carbon, marine microorganisms produce and consume...

Jet stream intraseasonal oscillations drive dominant ecosystem variations in Oregon’s summertime coastal upwelling system

Creator:: Bane, John M., Spitz, Yvette H., Letelier, Ricardo M., and Peterson, William T.
Abstract:: Summertime wind stress along the coast of the northwestern United States typically exhibits intraseasonal oscillations (ISOs) with periods from ≈15 to 40 days, as well as fluctuations on the 2- to 6-day “weather-band” and 1-day diurnal time scales. Coastal upwelling of cool, nutrient-rich water is driven by extended periods of...

Absolute humidity modulates influenza survival, transmission, and seasonality

Creator:: Shaman, Jeffrey and Kohn, Melvin
Abstract:: Influenza A incidence peaks during winter in temperate regions. The basis for this pronounced seasonality is not understood, nor is it well documented how influenza A transmission principally occurs. Previous studies indicate that relative humidity (RH) affects both influenza virus transmission (IVT) and influenza virus survival (IVS). Here, we reanalyze...

An approach to designing a national climate service

Creator:: Miles, E. L., Snover, A. K., Whitely Binder, L. C., Sarachik, E. S., Mote, P. W., and Mantua, N.
Abstract:: Climate variability and change are considerably important for a wide range of human activities and natural ecosystems. Climate science has made major advances during the last two decades, yet climate information is neither routinely useful for nor used in planning. What is needed is a mechanism, a national climate service...

The effect of climate variation on agro-pastoral production in Africa

Creator:: Stige, Leif Christian, Stave, Jørn, Chan, Kung-Sik, Ciannelli, Lorenzo, Pettorelli, Nathalie, Glantz, Michael, Herren, Hans R., and Stenseth, Nils Chr.
Abstract:: Using national crop and livestock production records from 1961–2003 and satellite-derived data on pasture greenness from 1982–2003 we show that the productivity of crops, livestock, and pastures in Africa is predictably associated with the El Niño Southern Oscillation and the North Atlantic Oscillation. The causal relations of these results are...

Predicting global atmospheric ice nuclei distributions and their impacts on climate

Creator:: DeMott, P. J., Prenni, A. J., Liu, X., Kreidenweis, S. M., Petters, M. D., Twohy, Cynthia, Richardson, M. S., Eidhammer, T., and Rogers, D. C.
Abstract:: Knowledge of cloud and precipitation formation processes remains incomplete, yet global precipitation is predominantly produced by clouds containing the ice phase. Ice first forms in clouds warmer than −36 °C on particles termed ice nuclei. We combine observations from field studies over a 14-year period, from a variety of locations...

Vailulu’u Seamount, Samoa: Life and death on an active submarine volcano

Creator:: Staudigel, Hubert, Hart, Stanley R., Pile, Adele, Bailey, Bradley E., Baker, Edward T., Brooke, Sandra, Connelly, Douglas P., Haucke, Lisa, German, Christopher R., Hudson, Ian, Daniel Jones, Koppers, Anthony A. P., Konter, Jasper, Lee, Ray, Pietsch, Theodore W., Tebo, Bradley M., Templeton, Alexis S., Zierenberg, Robert, and Young, Craig M.
Abstract:: Submersible exploration of the Samoan hotspot revealed a new, 300-m-tall, volcanic cone, named Nafanua, in the summit crater of Vailulu’u seamount. Nafanua grew from the 1,000-m-deep crater floor in <4 years and could reach the sea surface within decades. Vents fill Vailulu’u crater with a thick suspension of particulates and...

New insights into bacterial acquisition of phosphorus in the surface ocean

Creator:: White, Angelicque E.
Abstract:: Since 1958 when Alfred C. Redfield (1) recognized the similarity between the ratios of elements in living biomass and those dissolved in the surrounding seawater, we have understood that microorganisms largely control the concentrations, distribution, and molecular makeup of nutritional resources in the ocean. The primary elemental ingredients for life,...

Geochemical proxies of North American freshwater routing during the Younger Dryas cold event

Creator:: Carlson, Anders E., Clark, Peter U., Haley, Brian A., Klinkhammer, Gary P., Simmons, Kathleen, Brook, Edward J., and Meissner, Katrin J.
Abstract:: The Younger Dryas cold interval represents a time when much of the Northern Hemisphere cooled from ≈12.9 to 11.5 kiloyears B.P. The cause of this event, which has long been viewed as the canonical example of abrupt climate change, was initially attributed to the routing of freshwater to the St....

Delayed upwelling alters nearshore coastal ocean ecosystems in the northern California current

Creator:: Barth, John A., Menge, Bruce A., Lubchenco, Jane, Chan, Francis, Bane, John M., Kirincich, Anthony R., McManus, Margaret A., Nielsen, Karina J., Pierce, Stephen D., and Washburn, Libe
Abstract:: Wind-driven coastal ocean upwelling supplies nutrients to the euphotic zone near the coast. Nutrients fuel the growth of phytoplankton, the base of a very productive coastal marine ecosystem [Pauly D, Christensen V (1995) Nature 374:255–257]. Because nutrient supply and phytoplankton biomass in shelf waters are highly sensitive to variation in...
