Revealing the Ocean's Hidden Fertilizer Marine Plants Play Major Role in Phosphorus Cycling
Ocean's Hidden Fertilizer Marine Plants Phosphorus Cycling
2015/5/25
Phosphorus is one of the most common substances on Earth. An essential nutrient for every living organism—humans require approximately 700 milligrams per day—we are rarely concerned about consuming en...
NITROGEN AND PHOSPHORUS CYCLING IN MIDWESTERN AGRICULTURAL WETLANDS IN RESPONSE TO ALTERED HYDROLOGIC REGIMES
Wetland soil Midwest agriculture
2015/1/16
The transfer of nutrients from US Midwest croplands into surface waters causes eutrophication and a decline in water quality. Temporary retention of nutrient-rich runoff in constructed wetlands can he...
Characterization of alkaline phosphatase activity in the North and South Pacific Subtropical Gyres: Implications for phosphorus cycling
alkaline phosphatase activity iin the North South Pacific Subtropical Gyres:phosphorus cycling
2014/4/8
We characterized alkaline phosphatase (AP) activity (APA) and report AP kinetic parameters in the North and South Pacific Subtropical Gyres (NPSG and SPSG, respectively) to evaluate the relative impor...
Phosphonates and particulate organic phosphorus cycling in an anoxic marine basin
Phosphonates particulate organic phosphorus
2014/5/19
Total particulate phosphorus (TPP), particulate inorganic P (PIP), and particulate organic P (POP) concentrations
were measured in a year-long series of sediment trap samples collected throughout the...

The phylogenetic composition of bacterial communities varies along the salinity gradient of estuaries, one notable
pattern being the prevalence of alpha- and beta-proteobacteria in salt- and freshwat...
Phosphorus cycling in the North Pacific Subtropical Gyre using cosmogenic 32P and 33P
Phosphorus cycling North Pacific Subtropical Gyre cosmogenic 32P and 33P
2014/5/27
The North Pacific Subtropical Gyre (NPSG) has been hypothesized to be in transition from a nitrogen (N)-limited system to one predominantly limited by phosphorus (P) as a result of a two-decade-long s...
Iron-sulfur-phosphorus cycling in the sediments of a shallow coastal bay: Implications for sediment nutrient release and benthic macroalgal blooms
Iron-sulfur-phosphorus cycling in the sediments shallow coastal bay:sediment nutrient release benthic macroalgal blooms
2014/5/26
We conducted a study to determine the seasonal relationship between iron, sulfur, and phosphorus in the upper sediments and pore waters of a shallow intercoastal bay. From April 1999 to September 2000...
