The rates of primary production and new production will be                      studied at the GOFS Pacific Ocean time-series sites site,                       Station Aloha (23oN 158oW) using mixed layer measurements of                    oxygen, argon, nitrogen, radon-222 and the stable isotope ratio                 of 02.  The primary goal is to constrain the rates of                           biological processes by comparing results from the geochemical                  gas method with independent in vitro incubation experiments and                 sediment trap fluxes.  Proposed sampling frequency is monthly.                  Preliminary results demonstrate that highly accurate and                        precise measurements of dissolved gas concentrations and                        isotopic composition can be made using mass spectrometry.                       Calculation of oxygen loss to the atmosphere using data from                    four cruises at Station P in 1987 and 1988 yield new production                 rate estimates within a factor of two of values determined                      independently by in vitro incubations and sediment trap                         measurements.  Geochemical and biological production estimates                  appear to be consistent in this part of the ocean which is a                    dramatic contrast with recent findings in subtropics.
