Phosphorous cycling in the Gulf of Maine : a multi-tracer approach
… purification and measurement of 32p and 33p in rainwater and in inorganic, organic and particulate pools in seawater. In order to constrain the input ratio of 33p/32p, rain samples were collected and measured continuously for 32p and 33p, as well as 7Be and 21OPb, from March 1996 to March …

Phosphonate biogeochemical cycling in the marine environment: from an ocean scale to a molecular scale
… Sea, a chronically P-limited basin, using 33P and enzymatic assays. We showed that phosphonate production was low but consumption was high, suggesting that phosphonate production and consumption may be spatially or temporally decoupled. We also explored phosphonate production in the model …

Phosphorus physiology of the marine cyanobacterium Trichodesmium
… by measuring uptake rates and uptake kinetics of 33Pi and DOP (using alpha labeled adenosine-5’-triphosphate 33P-ATP as a model P ester compound). The in situ uptake rates suggest that the contribution of P ester to total P uptake can be greater than 25% for Trichodesmium, and therefore P esters …

Dietary Effects on the Stoichiometry of Growth, Regulation, and Wastes of Ozark Stream Insect Detritivores
… models. Subsequent experiments used 33P and 14C as microbial tracers to examine effects of diet leaf type and nutrient content, as well as taxonomic identity, on incorporation efficiency of microbial C and P by the detritivorous caddisflies Pycnopsche lepida, Lepidostoma sp., and …
