Consensus Reference Material Collection Data of marine dissolved organic matter collected in the Florida Strait between 2019 and 2023

Abstract

The laboratory of Prof. Dennis A. Hansell at the University of Miami is supported by the U.S. National Science Foundation to provide the international community of marine dissolved organic matter analysts the reference waters needed for testing their analytical results against those of a select group of expert analysts.

Three depths of the water column are sampled in the Florida Strait, typically twice each year, to collect and distribute those waters as reference materials. The deepest water (i.e., deep seawater reference (DSR)) is collected in the Florida Straits at 700 m depth. A mid depth seawater reference (MSR), is collected at 150 m depth and surface seawater reference (SSR) is collected at 5 m. In the data table that follows, the relevant information for each collection during NSF Grant OCE-1844886, awarded to the Hansell laboratory, is provided. These details include the ship employed and its cruise designations, the dates of collection, the batch and lot numbers designated for the reference waters, the locations and depths sampled, the concentrations of dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) in each lot. Finally, hyperlinks to the associated CTD and underway data, archived by RVDATA.US, are provided.
