Dr. Jia-Zhong Zhang is a principal investigator in charge of nutrient program at AOML. His lab has developed a number of analytical methods for low-level nutrient measurements widely used in oligotrophic waters as well as the EPA nutrient methods for coastal waters with varying salinity. Dr. Zhang has been funded by NOAA’s coastal program to study the sediment-water exchange of phosphorus in Florida Bay and its role in ecosystem functioning. He is a co-PI in the GO-SHIP global repeat hydrography program currently funded by the NOAA climate program office. The GO-SHIP program aims to quantify decadal changes in heat, fresh water, carbon, nutrients, oxygen, and trace gases in the global ocean. Nutrient measurements in this program are essential in identifying the hydrographic eature, estimating anthropogenic carbon in the ocean and in studying ocean biogeochemical cycles. The field observations are executed in each major ocean basin on board the NOAA Ship Ronald H. Brown. Dr. Zhang earned his Ph. D in Marine and Atmospheric Chemistry from the Rosenstiel School of Marine and Atmospheric Science (RSMAS) at the University of Miami.
