Cell densities of Parmales (a group of siliceous marine phytoplankton) were determined in
81 water samples from depths of 0–60 m on a monthly basis from October 2009 and October
2010 in Magdalena Bay, Mexican Pacific coast. The highest cell densities of Parmales were
recorded in sub-surface waters between 0 and 15 m water depth and reached maximum cell
densities of up to 40× 103 cells L− 1 in July at 10 m depth. In total five Parmales species
were identified: Triparma columacea f. columacea, T. retinervis f. retinervis, T. laevis f …

Abstract
Cell densities of Parmales (a group of siliceous marine phytoplankton) were determined in 81 water samples from depths of 0–60 m on a monthly basis from October 2009 and October 2010 in Magdalena Bay, Mexican Pacific coast. The highest cell densities of Parmales were recorded in sub-surface waters between 0 and 15 m water depth and reached maximum cell densities of up to 40 × 103 cells L−1 in July at 10 m depth. In total five Parmales species were identified: Triparma columacea f. columacea, T. retinervis f. retinervis, T. laevis f. mexicana, T. strigata and Tetraparma insecta. The present study suggests that cell densities of Parmales are associated with increased nutrient levels during the upwelling period from April to July.
