近日，中国地质大学生物地质与环境地质国家重点实验室宋虎跃副研究员及合作者在国际地学领域权威期刊《GEOLOGY》上发表题目“Uranium and carbon isotopes document global-ocean redox-productivity relationships linked to cooling during the Frasnian-Famennian mass ex...
Blooms of the coccolithophore Emiliania huxleyi regionally act as an important source of dimethyl sulfide (DMS) and calcium carbonate and alter the optical properties of the surface mixed layer (Balch...
On any given day Naval vessels travel the world's oceans, nearshore exercises take place, and at times, real operations occur where lives and equipment are in harm's way. Accurately predicting environ...

We review the current distribution of lead and lead isotopes in the ocean with regard to the evolving pattern of human emissions during the past decades and centuries.
A Decade of Directly Measured Sediment N2 Fluxes:What Can Narragansett Bay Tell Us About the Global Ocean Nitrogen Budget?
Directly Measured Sediment N2 Fluxes Narragansett Bay Global Ocean Nitrogen Budget
2015/7/17
The tight coupling between nitrogen and carbon cycling has important implications for global climate. These two cycles are under growing anthropogenic pressures (e.g., warming temperatures, changes in...
Taking the Pulse of Marine Ecosystems: The Importance of Coupling Long-Term Physical and Biological Observations in the Context of Global Change Biology
Coupling Long-Term Physical Biological Observations
2015/7/16
Research programs that co-locate environmental sensors with "biology" can enable the linking of environmental data with changes in biological or ecological processes. The coastal and marine Long Term ...
GODAE: The Global Ocean Data Assimilation Experiment
GODAE Global Ocean Data Assimilation Experiment
2015/7/6
During 1996 and 1997, Neville Smith and Michel Lefèbvre developed the Global Ocean Data Assimilation Experiment (GODAE) concept (Smith and Lefèbvre, 1997). Its central idea was to conduct a 10-year in...
Smothered oceans: Extreme oxygen loss in oceans accompanied past global climate change
Smothered oceans Extreme oxygen loss oceans accompanied past global climate change
2015/3/4
Seafloor sediment cores reveal abrupt, extensive loss of oxygen in the ocean when ice sheets melted roughly 10,000-17,000 years ago, according to a study from the University of California, Davis. The ...
Research on global path planning based on ant colony optimization for AUV
autonomous underwater vehicle (AUV) path planning ant colony optimization path smoothing
2011/9/9
Path planning is an important issue for autonomous underwater vehicles (AUVs) traversing an unknown environment such as a sea floor, a jungle, or the outer celestial planets. For this paper, global pa...
