Patchiness of phytoplankton and primary production in Liaodong Bay, China.

摘要: A comprehensive study of water quality, phytoplankton biomass, and photosynthetic rates in Liaodong Bay, China, during June July 2013 revealed two large patches high biomass production with dimensions on the order 10 km. Nutrient concentrations were above growth-rate-saturating throughout bay, possible exception phosphate at some stations. The presence therefore appeared to reflect distribution temperature variation light penetration restricted by turbidity. There was no patch or a third, linear characteristics suitable for rapid growth; absence bloom that likely reflected fact width less than critical size required overcome losses turbulent diffusion. bottom waters virtually all eastern half bay below depth mixed layer, lowest oxygen concentrations, 3-5 mg L-1, found part bay. column much remainder within both surface exceeded 5 L-1.
