Aerobic hydrogen production and dinitrogen fixation in the marine cyanobacterium Trichodesmium erythraeum IMS101
(2008-11)
Rates of hydrogen production and acetylene reduction were measured in aerobic cultures of the marine cyanobacterium Trichodesmium erythraeum IMS101 grown in a supplemented seawater medium low in combined inorganic nitrogen. ...
Predicting and verifying the intended and unintended consequences of large-scale ocean iron fertilization
(2008)
Ocean iron fertilization (OIF) is being considered as a strategy for mitigating rising atmospheric CO2 concentrations. One model for implementation is the sale of carbon offsets. Modeling studies predict that OIF has the ...
Enhanced ocean carbon storage from anaerobic alkalinity generation in coastal sediments
(European Geosciences Union, 2008-09)
The coastal ocean constitutes the crucial link between land, the open ocean and the atmosphere. Furthermore, its shallow water column permits close interactions between the sedimentary and atmospheric compartments, which ...
Quantifying particle dispersal in aquatic sediments at short time scales: model selection
(2008)
In a pulse-tracer experiment, a layer of tracer particles is added to the sediment-water interface, and the down-mixing of these particles is followed over a short time scale. Here, we compared different models (biodiffusion, ...
Inferred influence of nutrient availability on the relationship between Sun-induced chlorophyll fluorescence and incident irradiance in the Bering Sea
(American Geophysical Union, 2000 Florida Ave., N.W. Washington DC 20009 USA, [mailto:service@agu.org], [URL:http://www.agu.org], 2008-08)
This study examines variability in the relationship between Sun-induced chlorophyll fluorescence and incident solar irradiance as a potential diagnostic of the nutritional status of phytoplankton. The study site is the ...
Reducing the risk of lethal encounters: vessels and right whales in the Bay of Fundy and on the Scotian Shelf
(2008)
The North Atlantic right whale Eubalaena glacialis is endangered, in part, due to vessel-strike mortality. We use vessel traffic and right whale survey data (similar to 3 nautical miles [n miles], similar to 5.6 km resolution) ...
