Data on sediment nitrogen loadings and nitrogen in the biomass of seagrasses from Sungai Pulai estuary (Johor, Malaysia)

摘要

This paper presents data on nitrogen characteristics in a tropical seagrass meadow located in Sungai Pulai estuary (Johor, Malaysia) and is related to the article “Nitrogen dynamics in tropical seagrass meadows under heavy anthropogenic influence” [1]. Field sampling conducted from August 2015 to May 2016 aimed to collect sediments and seagrass tissues for analysis of nitrogen elemental content and stable isotope values. Sediment samples and seagrass tissue (above-ground and below-ground parts) were collected by using PVC cores. The information is presented as unprocessed and partially data, which incorporates nitrogen content (in %) and δ15N values (‰) of sediment and seagrass tissue samples. Nitrogen loadings in the seagrass sediments, as based on down-core data of sediment samples up to 30 cm depths, should be read with [1] to comprehend the baseline nitrogen dynamics of the study area.
