nutrientsdi 06jan 060107 through 060202 Samples taken from Go-Flo bottles and analyzed within 4 hours on board the LM Gould during the January LTER Cruise. Samples not run within 4 hours were frozen at -70 Celsius and run at a later date during the cruise. All samples run on an Lachat QuikChem 8000 Flow Injection Analysis nutrient analyzer. year, day, date, grid line, grid station, GMT (hour), GMT (min), latitude (degrees), latitude (minutes), longitude (deg.), longitude (min.), event #, CTD bottle #, irradiance (%), depth (m), phosphate (uM), silicate (uM), nitrite (uM), nitrate (uM), ammonium (uM), nitrate+nitrite (uM) nitrate (uM) from difference of measured variables nitrite + nitrate (uM) and nitrite (uM). Water was sampled from all depths at all cruise stations. Water from Go-Flo bottles was sub-sampled directly into acid washed 50ml Falcon tubes and stored, up to 4 hours, at 4 degrees Celsius until analysis on a Lachat QuikChem 8000 nutrient analyzer. Samples not run within 4 hours were frozen at -70 degrees Celsius until anlysis. Frozen samples were stored in new 50ml Falcon tubes. Frozen samples collected within the euphotic zone of the CTD cast were filtered through 0.45um polypropylene syringe-tip filters before freezing, all others were collected directly into the 50ml tubes. Water was sampled from Go-Flo bottles off a side-deployed rosette at all depths sampled (usually eleven discreet depths). nutrients, phosphate, silicate, nitrate, nitrite, ammonium ASCII, comma separated online lter lmg0601.nuts Dr. Maria Vernet, Scripps Institution of Oceanography, San Diego,CA mvernet@ucsd.edu Dr. Maria Vernet, Scripps Institution of Oceanography, San Diego, CA mvernet@ucsd.edu Wendy Kozlowski, Julie Schram, Jenny Husby, Karie Sines Karie Sines Karie Sines Karie Sines Karie Sines 070702 "A Suggested Protocol for Continuous Flow Automated Analysis of Seawater Nutrients" Louis I.
