Phytoplankton distribution along the eastern coast of the U.S.A.—VII. Mean cell concentrations and standing crop

Remote sensing of phytoplankton community composition along the northeast coast of the United States

“…Spatial and seasonal variations of satellite-derived phytoplankton taxonomic groups from this study generally agreed with the cell count observations and with previous work (e.g. Marshall, 1984aMarshall, , 1984bMarshall & Cohn, 1987;Marshall & Ranasinghe, 1989;Marshall et al, 2006). Cell abundances of some major phytoplankton functional groups (e.g.…”

“…The spatial distributions and the time-series patterns of phytoplankton composition derived from CHEMTAX method agreed reasonably with cell count observations. Phytoplankton composition over the U.S. northeastern continental shelf including studies involving NOAA National Marine Fisheries Service (NMFS) based cruises from 1969 through 1985 showed over 600 algal taxa recorded for this region (Marshall & Ranasinghe, 1989). The major components included diatoms, a diverse group of phytoflagellates, plus pico-phytoplankton (b3 μm) composed predominantly of cyanobacteria and chlorophytes (Marshall, 1984a(Marshall, , 1984b.…”

Feeding by Phototrophic Red‐Tide Dinoflagellates on the Ubiquitous Marine Diatom Skeletonema costatum

“…Skeletonema costatum is a ubiquitous diatom and often dominates the abundance and/or biomass of diatoms and total phytoplankton in the coastal waters due to its very high maximum growth rates of three to four divisions per day (Balkis 2003;Durbin and Durbin 1981;Marshall and Ranasinghe 1989;Pratt 1965;Ramaiah and Furuya 2002;Reid, Lange, and White 1985). So far, heterotrophic protists (Hansen 1992;Jeong et al 2004b) and copepods (Conover 1956;Deason 1980;Martin 1965;Paffenhöfer 1976) have been known to be two major grazers on S. costatum in marine plankton communities.…”

Photoprotection and xanthophyll‐cycle activity in three marine diatoms1

“…We interpret this plasticity as a functional trait that contributes to its ecological success in the turbulent environment where it grows. This species dominates the algal community during the spring bloom in the northern Adriatic Sea (Totti and Artegiani 2001) and in coastal waters of the northwest Atlantic (Marshall and Ranasinghe 1989). Chaetoceros as a genus might be seen as having high photophysiological plasticity since other species have the same acclimation behavior with respect to light variations ( C. muelleri Lemmerm., Olaizola and Yamamoto 1994; C. gracilis Pant., Kashino and Kudoh 2003).…”

“…The three species used as models are Skeletonema marinoi, Chaetoceros socialis, and Thalassiosira rotula. The first species blooms in the coastal area of the Adriatic Sea in the late winter (Totti andArtegiani 2001, Sarno et al 2005), while the second co-occurs with other species during the spring bloom in some coastal areas (Marshall andRanasinghe 1989, Totti andArtegiani 2001), and the third grows in more offshore ecosystems (Syvertsen 1977). Different photoresponses were determined, depending mainly on the species but also on the growth PFD acclimation of the cells.…”
