Polyphosphate and associated measurements from water and particulate samples collected from 13 locations in the Great Lakes in July-Aug 2018 on R/V Blue Heron cruise BH18-09

Abstract

Water and particulate samples were collected from 13 locations in the Great Lakes to quantify polyphosphate (polyP) under a range of phosphorus (P) levels. The dataset also includes other related parameters, including particulate phosphorus (PP), chlorophyll-a (Chl-a), activities of alkaline phosphatase (APase), soluble reactive phosphorus (SRP), particulate carbon (PC), and particulate N (PN). Ratios of polyP:PP reported in the literature are also included for comparison. The supplement files include CTD data (temperature, oxygen, Chl-a, and light transmission) and the phytoplankton abundance data. Phytoplankton data are originally from the Great Lakes Environmental Database (GLENDA) collected by the US Environmental Protection Agency Great Lakes National Program Office (EPA GLNPO).
