A review of phytoplankton composition within Chesapeake Bay and its tidal estuaries
Abstract
Based on a continuous 20-year data base of monthly sampling in Chesapeake Bay and tidal regions of its major tributaries, 1454 phytoplankton taxa have been identified in these waters. They represent a diverse assemblage of species with a dominant diatom flora throughout the year, in addition to large seasonal representation by chlorophytes, cyanobacteria, cryptophytes and dinoflagellates. Included among this flora were 34 potential harmful or toxin producing species. The phytoplankton compositions associated with the seasonal successional patterns are discussed, in addition to characterizing the dominant floral relationships, with comparison to early composition records within the Bay. Several of the present day most common taxa were similar to those reported in sediment cores from the Bay dating to periods prior to European settlement. Comparison with collections made ∼8 decades ago (1916–1922) within Chesapeake Bay indicated several of the same dominant flora remain dominant today; however, their cell concentrations are now significantly greater along with an increased diversity of species compared with these earlier studies.

Since the 1990s there has been an increase in M. polykrikoides bloom occurrence and intensity throughout Virginia waters with a geographic expansion from the York River primarily southwards to the James River and to a lesser degree northwards to the Rappahannock River.
“Since the 1990s there has been an increase in bloom occurrence and intensity throughout Virginia waters (Marshall, 1996;Marshall et al., 2005) with a geographic expansion of the blooms from the York River, primarily southwards to the James River (Marshall and Egerton, 2009a), and to a lesser degree northwards to the Rappahannock River (Marshall and Egerton, 2009b).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
