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...
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...
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...
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...
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...
