Seasonal variations in the phytoplankton community in the north-eastern Sea of Marmara and a species list
This paper describes phytoplankton abundance data collected in the Sea of Marmara in 2000 and identifies new species to the region. The quantitative sampling was carried out monthly at 3 stations and seasonally at 6 stations at depths of 0.5, 5, 10 and 20 m. Additionally, vertical samplings by plank...

The phytoplankton density was lower at the 20 m depths because of the low light penetration property of the Sea of Marmara.
