A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry reflecting changing climate conditions over the past 35 million years.The...
When waves break in the ocean, they inject tiny particles into the air, called aerosols, that carry organic molecules more than 5,000 years old. The discovery, published in Science Advances by Steven ...
Paleoceanographic and marine paleoclimatic investigations commonly use deep, open-ocean sediments or coral reefs to establish a continuous record of past global environmental changes because they both...
Nitrogen is an essential nutrient for living systems in the ocean; it is a component of proteins, chlorophyll, and nucleic acids. In the oceans, nitrogen exists as a dissolved gas (N2), dissolved orga...
The Black Sea is the world's largest marine anoxic basin. The Black Sea's water below a depth of ~100 m is enriched with hydrogen sulfide that formed after the intrusion of seawater as a result of sea...
The second edition of Michael Pilson's classic textbook An Introduction to the Chemistry of the Sea is a welcome addition to introductory oceanography texts. This new edition, recently published by Ca...
As the world’s ice diminishes in the face of climate change—from the dramatic decline in Arctic sea ice, to thinning at the margins of both the Greenland and Antarctic ice sheets, to retreating mo...
Seismic stratigraphic and drill data from Antarctic continental margins have provided much direct evidence concerning ice sheet evolution as Earth’s climate cooled from the warmth of the Eocene. S...
The Ross Sea in a Sea of Change     Ross Sea  Sea       2015/7/15
The Ross Sea, the most productive region in the Antarctic, reaches farther south than any body of water in the world. While its food web is relatively intact, its oceanography, biogeochemistry, and se...
Sea surface temperature (SST) measurements are required by operational ocean and atmospheric forecasting systems to constrain modeled upper ocean circulation and thermal structure. The Global Ocean Da...
Coincident with shifting monsoon weather patterns over India, the phytoplankter Noctiluca miliaris has recently been observed to be dominating phytoplankton blooms in the northeastern Arabian Sea dur...
Where's the remaining oil from the 2010 Deepwater Horizon disaster in the Gulf of Mexico? The location of 2 million barrels of oil thought to be trapped in the deep ocean has remained a mystery. Unti...
The location of 2 million barrels of oil thought to be trapped in the deep ocean has remained a mystery. Until now. Scientist David Valentine of the University of California, Santa Barbara (UCSB) and...
We analyzed liver samples from 322 ringed seals (Pusa hispida) collected from Cumberland Sound (southeast Baffin Island) to test our ability to differentiate between carbon sources in near apex preda...
Moored sediment traps were deployed for 1 yr at depths of 120, 600, and 3500 m in the water column to investigate the trace metal (M) (Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) composition, sources, ...
