Accumulation of prokaryotic remains during organic matter diagenesis in surface sediments off Peru
Accumulation of prokaryotic organic matter diagenesis
2014/4/18
Bacterial biomarkers (D-amino acids and muramic acid) were investigated in surface sediments (0–1 cm) at 22
stations in the Peru margin. Concentrations were used to quantitatively estimate the relati...
Assessing environmental control on dinoflagellate cyst distribution in surface sediments of the Benguela upwelling region (eastern South Atlantic)
environmental control dinoflagellate cyst distribution surface sediments the Benguela upwelling region
2014/4/21
Organic-walled dinoflagellate cyst assemblages in surface sediments of the Benguela Current Upwelling System (eastern South Atlantic) show geographic patterns that cannot entirely originate from cyst ...
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...
Microscale mineralization pathways in surface sediments: A chemical sensor study in Lake Baikal
Microscale mineralization pathways surface sediments A chemical sensor study Lake Baikal
2014/5/4
We used an array of ion-selective electrodes (oxygen [O2], hydrogen [H+], carbonate [CO32-], calcium [Ca2+], ammonium [NH4+], and nitrate [NO3-]) with a micromanipulator to study mineralization proces...
Distribution and retention of effluent nitrogen in surface sediments of a coastal bay
Distribution retention of effl uent nitrogen
2014/5/19
Anthropogenic nitrogen (N) often causes coastal eutrophication, yet little is known about the fate and retention
of effluent N in coastal waters and, hence, about the system’s ability to assimi...
Quantitative and qualitative relationships between planktonic diatom communities and diatom assemblages in sedimenting material and surface sediments in Lake Baikal, Siberia
Quantitative qualitative relationships Lake Baikal Siberia
2014/5/21
Endemic planktonic diatoms are a major component of Lake Baikal sediments during interglacial periods. To
investigate how these diatom assemblages are altered during sediment formation, quantitative ...
