TLDR
In this article, a spectrophotometric method is described for the determination of dissolved mono- and polysaccharides in seawater, based upon the well known alkaline ferricyanide reaction, but uses the reagent 2,4,6-tripyridyl-s-triazine (TPTZ) to give a strongly colored complex with the reduced iron.About:

Polysaccharide aggregation as a potential sink of marine dissolved organic carbon
TL;DR: It is shown that the formation of polysaccharide particles is an important pathway to convert dissolved into particulate organic carbon during phytoplankton blooms, and can be described in terms of aggregation kinetics.

Chemical Biomarkers in Aquatic Ecosystems
TL;DR: This paper presents a meta-analyses of metabolic Synthesis and biomarker applications to Ecology and Paleoecology using Atomic Weights of Elements and Conversion Factors, as well as some of the methods used in this work to derive these units.

Cellular and extracellular production of carbohydrates and amino acids by the marine diatom Skeletonema costatum: diel variations and effects of N depletion
TL;DR: This study provides new evidence of β-1,3-glucan supplying carbon skeletons for synthesis of amino acids and protein in diatoms and strongly indicates that β-carboxylation provides C4 precursors for amino acid synthesis.
Journal ArticleDOI
Formation and global distribution of sea-surface microlayers
TL;DR: In this paper, a study of surfactants in the sea-surface microlayer (SML) in different regions of the ocean (subtropical, temperate, polar) suggests that this interfacial layer between the ocean and atmosphere covers the ocean's surface to a significant extent.
Journal ArticleDOI
Fibrillar polysaccharides in marine macromolecular organic matter as imaged by atomic force microscopy and transmission electron microscopy
TL;DR: In this article, colloid samples from the Gulf of Mexico and Middle Atlantic Bight of nominal sizes 1-200 nm were collected by cross-flow ultrafiltration, diafiltered, and freeze-dried.

TL;DR: Carbohydrate concentrations in depth profiles from the Atlantic and Pacific Oceans, the Gulf of Mexico, and the Gerlache Strait (Antarctica) were determined by MBTH analysis without hydrolysis and after dilute HCI and concentrated H2SO4.

Dissolved carbohydrates in seawater. I, A precise spectrophotometric analysis for monosaccharides
TL;DR: A relatively precise and rapid method for the analysis of total dissolved monosaccharides at the concentrations that occur in seawater is described which uses 1-ml quantities for each analytical and control replicate.
