TL;DR: In this paper, a correlation matrix between the phosphorus fractions, determined by serial extraction, and 14 sediment variables was computed, and it was concluded that calcium phosphate is not a major constituent of the sediment-phosphorus reservoir.

Abstract: In order to determine the primary factors related to the accumulation of phosphorus in estuarine sediments, a study of phosphorus fractions in sediments of the Delaware River Estuary was undertaken. A correlation matrix between the phosphorus fractions, determined by serial extraction, and 14 sediment variables was computed. Total phosphorus and total inorganic phosphorus in the sediment-phosphorus reservoir decreases with increasing salinity. This variation is correlated with decreasing iron oxyhydroxide content in the sediment. Neither clay content nor calcium carbonate content appear to be significantly correlated with variation in total inorganic phosphorus content in the fine-grained sediments of this estuary. Although calcium phosphate is concluded to be a major constituent of the sediment-phosphorus reservoir, there was no evidence found that it is authigenic in this environment.

Transformation of particle-bound phosphorus at the land-sea interface
TL;DR: The distribution of particle-bound phosphorus in the suspended matter of the Chesapeake Bay was partitioned by a sequential chemical leaching technique into three major fractions: (1) an organic and loosely-bound fraction (Org-P), (2) an iron-associated fraction extracted with citrate-dithionate-bicarbonate (CDB-P) and (3) a detrital (apatite rich) fraction extracting with hydrochloric acid (HCl-P).

Low phosphorus sediments in a hypersaline marine bay
TL;DR: Shark Bay, Western Australia is a large, shallow, hypersaline coastal lagoon with low nutrient input as discussed by the authors, and the sediment organic C, total N, and total P were measured in the sediments along the salinity gradient.

TL;DR: In this article, the spatial and vertical distribution of phosphorus was studied by analysing sediment samples from 345 stations of different seabed substrate types in archipelago areas of the northern Baltic Sea (Svealand in Sweden and Aland, SW Finland and W Uusimaa in Finland).

Loss-on-ignition as an estimate of organic matter and organic carbon in non-calcareous soils
TL;DR: In this paper, a good correlation exists between loss-on-ignition and organic C values, determined by Tinsley's method, and regression lines and prediction limits are given from the data obtained.
