Analyse von Butylzinnverbindungen in Sedimenten mittels GC-AED
(Univ. Hamburg, 2007)
Organotin compounds are variously used industrial chemicals. One of the most toxicological relevant compounds is tributyltin (TBT). TBT has been used as an effective component in antifouling paints for decades. Thus, it ...
Laser ablation ICP-MS in paleoceanography
(Univ. Bremen, 2008)
The different benthic foraminiferal species (epibenthic as well as endobenthic) colonize wide areas of the ocean floor and are widely used for paleoceanographic reconstructions. To improve these reconstructions, it is an ...
The effect of acidic polysaccharides on the biogeochemistry of iron in the marine environment
(Univ. Bremen, 2008)
In the early 1990`s the first IPCC report stated the effect of anthropogenic CO2 emissions on global warming and John Martin`s Iron Hypothesis (Martin and J.H 1990), relating atmospheric dust deposition, a major source of ...
Influence of Species‐Specific Feeding Ecology on Mercury Concentrations in Seabirds Breeding on the Chatham Islands, New Zealand
(
- Environmental Toxicology and Chemistry
, 2021-01-20)
Mercury (Hg) is a toxic metal that accumulates in organisms and biomagnifies along food webs; hence, long‐lived predators such as seabirds are at risk as a result of high Hg bioaccumulation. Seabirds have been widely used ...
High field strength element systematics and Lu-Hf & Sm-Nd garnet geochronology of orogenic eclogites
(Univ. Frankfurt (Main), 2008)
Concerning the Bulk Silicate Earth (BSE), the depleted mantle and the continental crust are thought to balance the budget of refractory and lithophile elements, resulting in complementary trace element patterns. However, ...
Methane oxidation and carbon assimilation in marine sediments
(Univ. Bremen, 2008)
Anaerobe Oxidation of Methane, AOM, methanotrophy, stable isotope labeling, stable isotope probing, carbon assimilation, flow-through columns, ANME, Seep-SRB, Gullfaks, Tommeliten. - Anaerobic oxidation of methane (AOM) ...
Predictive modeling of organic pollutant leaching and transport behavior at the lysimeter and field scales
(Univ. Dresden, 2007)
Soil and groundwater pollution has become a global issue since the advent of industrialization and mechanized agriculture. Some contaminants such as PAHs may persist in the subsurface for decades and centuries. In a bid ...
Modeling the spatial and temporal variability of marine radiocarbon reservoir ages in the Late Quaternary
(Univ. Bremen, 2008)
Radiocarbon, reservoir age, ocean circulation, projection age, top-to-bottom age, B-P age. - In paleoceanography and paleoclimatology radiocarbon is frequently used to date carbonaceous samples of the past 50,000 years and ...
Mesoskopische Strukturen in kristallinen Systemen an zwei Beispielen aus Natur und Synthese
(Univ. Hamburg, 2006)
In dieser Arbeit werden zwei mesoskopische Systeme untersucht, zum ersten die ferroelastischen Domänen in Calcium-dotiertem Bleiphosphat, zum zweiten die oszillatorische Biomineralisation im Calcit und Aragonit von ...
