Interdisciplinary Studies Integrating the Black Sea Biogeochemistry and Circulation Dynamics
Interdisciplinary Studies Integrating Black Sea Biogeochemistry Circulation Dynamics
2015/8/3
The Black Sea is a deep (about 2 km) elliptic basin with zonal and meridional dimensions of approximately 1000 km and approximately 400 km, respectively, located roughly between 28° and 42°E longitude...
Steamy, humid mangrove forests; clear blue waters with colorful coral and fish; large river mouths and iceberg-covered coasts; meter-long tubeworms in the dark oceanic abyss: what is common to these v...
Determining the basic processes governing the biogeochemical structure of the water column is a key challenge for today's oceanographers. Knowledge of these basic processes for an aquatic system makes...
Quantifying the Impact of Atmospheric Deposition on the Biogeochemistry of Fe and Al in the Upper Ocean:A Decade of Collaboration with the US CLIVAR-CO2 Repeat Hydrography Program
Atmospheric Deposition Biogeochemistry of Fe Al in the Upper Ocean Collaboration CLIVAR-CO2 Repeat Hydrography Program
2015/7/17
The aerosol deposition of continental material and its partial dissolution in the surface ocean exerts an important control on the distribution of iron and other potentially limiting trace metal (TM) ...
Scientific Outcomes and Future Challenges of the Ocean Carbon and Biogeochemistry Program
Scientific Outcomes Future Challenges Ocean Carbon Biogeochemistry Program
2015/7/17
The ocean plays a major role in shaping Earth's climate, regulating levels of key atmospheric trace gases such as carbon dioxide on time scales of decades to millennia. Much progress has been made in ...

Integrating Biogeochemistry Ecology Ocean Data Assimilation Systems
2015/7/6
Monitoring and predicting the biogeochemical state of the ocean and marine ecosystems is an important application of operational oceanography that needs to be expanded. The accurate depiction of the o...
Arsenic and phosphorus biogeochemistry in the ocean: Arsenic species as proxies for P-limitation
Arsenic and phosphorus biogeochemistry the ocean: Arsenic species proxies for P-limitation
2014/4/2
Arsenic and phosphorus are biochemically very similar, and hence arsenate (As5+) is toxic by interfering with the energy metabolism, in particular during P limitation. However, many phytoplankton deto...
Effect of a flood event on the dynamics of phytoplankton and biogeochemistry in a large temperate Australian lagoon
a flood event on the dynamics phytoplankton biogeochemistry temperate Australian lagoon
2014/4/17
In episodically driven estuaries, nutrient delivery is typically confined to sporadic flow events, followed by intense biogeochemical recycling of nutrients. We document the response of a temperate la...
Remineralization of upper ocean particles: Implications for iron biogeochemistry
Remineralization upper ocean particles iron biogeochemistry
2014/4/17
The role of heterotrophic bacteria in iron recycling, the influence of complexation on iron remineralization,and iron mobilization rates from lithogenic vs. biogenic particulate iron (PFe) were examin...
Mixing and its effects on biogeochemistry in the persistently stratified, deep, tropical Lake Matano, Indonesia
persistently stratified deep tropical Lake
2014/4/16
In the . 590-m deep, tropical Lake Matano (Indonesia), stratification is characterized by weak thermal
gradients (, 2uC per 500 m) and weak salinity gradients (, 0.14% per 500 m). These gradients per...
