Interannual and Subdecadal Variability in the Nutrient Geochemistry of the Cariaco Basin
Interannual and Subdecadal Variability Nutrient Geochemistry Cariaco Basin
2015/7/17
The CARIACO Ocean Time Series program has made monthly measurements of oxygen, nutrients, and carbon system parameters (∑CO2, alkalinity, pH) in the Cariaco Basin since 1996. At the same time, sedimen...
Variability in optical particle backscattering in contrasting bio-optical oceanic regimes
Variability contrasting bio-optical oceanic
2014/4/8
Variability in the optical particle backscattering coefficient (bbp) is investigated in oceanic waters from two
sites, namely the BOUe′e pour l’acquiSition d’une Se′rie Optique a` Long termE site in ...
Temporal and spatial variability in the cycling of nitrogen within a constructed wetland: A whole-system stable-isotope-addition experiment
Temporal spatial variability in the cycling of nitrogen a constructed wetland A whole-system stable-isotope-addition experiment
2014/4/17
Constructed wetlands attenuate effluent nutrients, are hydrodynamically well defined, and are a useful proxy for the study of nitrogen (N) transformation in eutrophic natural systems. A whole-system s...
Effects of land use, urbanization, and climate variability on coastal eutrophication in the Baltic Sea
land use urbanization climate variability coastal eutrophication in the Baltic Sea
2014/4/17
Sedimentary records of organic matter inputs (stable nitrogen isotopes [d15N], nitrogen [N], and carbon [C] content), phytoplankton abundance (pigments, stable carbon isotopes [d13C]), and community c...
Variability of Pseudo-nitzschia and domoic acid in the Juan de Fuca eddy region and its adjacent shelves
Pseudo-nitzschia and domoic acid adjacent shelves
2014/4/17
The Juan de Fuca eddy is a toxic ‘‘hot spot.’’ Domoic acid (DA) was detected in the eddy during each of six
cruises over a 4-yr study, although Pseudo-nitzschia abundance and toxin concentrations wer...
Spatial variability of climate and land-use effects on lakes of the northern Great Plains
Spatial variability climate land-use on lakes of the northern Great Plains
2014/4/21
Evaluation of the effects of climate change and human activities on lakes requires improved understanding of how stressors interact and the degree to which individual sentinel lakes represent broad sp...
Spatial variability of stable isotopes and fossil pigments in surface sediments of Alaskan coastal lakes: Constraints on quantitative estimates of past salmon abundance
Spatial variability stable isotopes fossil pigments surface sediments Alaskan coastal lakes Constraints on quantitative estimates past salmon abundance
2014/5/4
We quantified spatial patterns of stable isotopes of N and C (δ15N, δ13C) and fossil pigment concentrations in the uppermost 10 mm of sediment (,10 yr) from 74 profundal locations and three spawning-s...
The optical volume scattering function: Temporal and vertical variability in the water column off the New Jersey coast
scattering function Temporal
2014/5/13
I present optical data collected offshore of the New Jersey coast at the Long Term Ecological Observatory LEO-

Variability of particulate seawater properties related to bottom mixed layer-associated internal waves in shallow water on a time scale of hours
particulate seawater properties bottom mixed layer-associated internal waves a time scale of hours
2014/5/20
To obtain information on relations between internal wave-controlled hydrographic variability in bottom mixed layers (BMLs) and particle-associated BML parameters, depth distributions of density, relat...
Acetate cycling in the water column of the Cariaco Basin: Seasonal and vertical variability and implication for carbon cycling
Acetate cycling in the water column Cariaco Basin Seasonal and vertical variability carbon cycling
2014/5/27
Acetate oxidation frequently has been used as proxy of organic carbon decomposition in marine anoxic sediments. However, the importance of acetate uptake in carbon cycling in marine anoxic water colum...
