The Oceanic Nutrient Laboratory is a fully equipped chemistry laboratory for standard nutrient analyses using ASTORIA-PACIFIC 305D Analyzer (4 channels)-or Technicon-Autoanalyzer-II segmented-flow (5 channels) analyzers. These are controlled by and their data acquired by laptop computers. Additionally, there are two laboratory versions of a fluorescent nutrient-sensor package for measuring nutrients (nitrate, nitrite, and ammonia) in seawater at the nanomolar level (Masserini and Fanning, 2000). Each consists of an XYZ autosampler and a three-module flow-injection system (one for each nutrient), three Hitachi high-sensitivity fluorometers (one for each module), and a laptop computer to control the system and acquire data. The laboratory is also equipped with a computer-controlled conductometric oxygen titrator. Extensive design and production facilities, critical to sensor development, are available within the College of Marine Science at the University of South Florida for electronic, hardware, and software modifications. The USF College of Marine Science possesses a full machine shop with a highly skilled staff of machinists and designers. Other laboratory facilities include a 6 Channel Gas Scintillation Radionuclide Detector System, Metter Toledo AG245 Analytical Balances, Mettler Toledo PB3002 Top Loading Balance (maximum weight 3100g), Fisher Scientific Muffle Furnace, VWR Scientific 1350 Gravity Oven, Milli-Q RG Deionized Water Polishing Systems, and a Sea-Bird Electronics SBE 21 Thermonsalinograph.
