Characterizing dissolved organic matter fluorescence with parallel factor analysis: a tutorial
Tập 6 Số 11 - Trang 572-579 - 2008
A sub‐fraction of dissolved organic matter fluoresces when excited with
ultraviolet light. This property is used to quantify and characterize changes in
dissolved organic matter (DOM) in aquatic environments. Detailed mapping of the
fluorescence properties of DOM produces excitation emission matrices (EEM),
which are well suited to multi‐way data analysis techniques (chemometrics).
Techniques such...
A simple and efficient method for the solid‐phase extraction of dissolved organic matter (SPE‐DOM) from seawater
Tập 6 Số 6 - Trang 230-235 - 2008
A simple protocol is presented for the solid‐phase extraction of dissolved
organic matter (SPE‐DOM) from seawater using commercially prepacked cartridges.
The method does not require major instrumentation and can be performed in the
field. Modified styrene divinyl benzene polymer type sorbents (Varian PPL and
ENV) and sorbents of a silica structure bonded with different hydrocarbon chains
(Varian ...
Relationship between wind speed and gas exchange over the ocean revisited
Tập 12 Số 6 - Trang 351-362 - 2014
The relationship between gas exchange and wind speed is used extensively for
estimating bulk fluxes of atmospheric gases across the air‐sea interface. Here,
I provide an update on the frequently used method of Wanninkhof (1992). The
update of the methodology reflects advances that have occurred over the past two
decades in quantifying the input parameters. The general principle of obtaining
a rela...
Application of the isotope pairing technique in sediments where anammox and denitrification coexist
Tập 1 Số 1 - Trang 63-73 - 2003
The isotope pairing technique (IPT) is a well‐established 15N method for
estimation of denitrification. Presence of anammox, the anaerobic oxidation of
NH4+ to N2 with NO2− results in violation of central assumptions on which the
IPT is built. It is shown that anammox activity causes overestimation of the N2
production calculated by the IPT. However, experiments with different additions
of 15NO3− ...
Inner filter correction of dissolved organic matter fluorescence
Tập 11 Số 12 - Trang 616-630 - 2013
The fluorescence of dissolved organic matter (DOM) is suppressed by a phenomenon
of self‐quenching known as the inner filter effect (IFE). Despite widespread use
of fluorescence to characterize DOM in surface waters, the advantages and
constraints of IFE correction are poorly defined. We assessed the effectiveness
of a commonly used absorbance‐based approach (ABA), and a recently proposed
controll...
Online δ13C analysis of volatile fatty acids in sediment/porewater systems by liquid chromatography-isotope ratio mass spectrometry

Evaluation of diagnostic pigments to estimate phytoplankton size classes
Tập 18 Số 10 - Trang 570-584 - 2020
AbstractPhytoplankton accessory pigments are commonly used to estimate
phytoplankton size classes, particularly during development and validation of
biogeochemical models and satellite ocean color‐based algorithms. The diagnostic
pigment analysis (DPA) is based on bulk measurements of pigment concentrations
and relies on assumptions regarding the presence of specific pigments in
different phytopla...
WACODI: A generic algorithm to derive the intrinsic color of natural waters from digital images
Tập 13 Số 12 - Trang 697-711 - 2015
AbstractThis document presents the WAter COlor from Digital Images (WACODI)
algorithm, which extracts the color of natural waters from images collected by
low‐cost digital cameras, in the context of participatory science and water
quality monitoring. SRGB images are converted to the CIE XYZ color space,
undergoing a gamma expansion and illumination correction that includes the
specular reflection ...
An approach to correct the effects of phytoplankton vertical nonuniform distribution on remote sensing reflectance of cyanobacterial bloom waters
Tập 15 Số 3 - Trang 302-319 - 2017
AbstractCyanobacterial blooms occur frequently in eutrophic lakes and their
potentially harmful effects affected the security of drinking water and food
sources, biodiversity, and economic activities, and attracted the attention of
general public worldwide. Cyanobacteria could move vertically in the water
column by regulating their buoyancy, which leads to the assumption of
homogeneous water inval...
Application of cross‐flow ultrafiltration for isolating exopolymeric substances from a marine diatom (Amphora sp.)
Tập 7 Số 6 - Trang 419-429 - 2009
The increasing recognition of the roles that exopolymeric substances (EPS) play
in the aquatic environment necessitates obtaining sufficient quantities of
purified EPS for exploration of its physical, chemical, and biological
properties, as well as for quantitative and structural analysis of its
composition. For this purpose, three preconcentration/ purification techniques,
i.e., 1) ethanol precip...
