Selective preservation of organic matter in marine environments; processes and impact on the sedimentary record
(Copernicus Publications on behalf of the European Geosciences Union, 2010-02-05)
The present paper is the result of a workshop sponsored by the DFG Research Center/Cluster of Excellence MARUM "The Ocean in the Earth System", the International Graduate College EUROPROX, and the Alfred Wegener Institute ...
The western Arctic boundary current at 152°W : structure, variability, and transport
From August 2002 to September 2004 a high-resolution mooring array was maintained across the western Arctic boundary current in the Beaufort Sea north of Alaska. The array consisted of profiling instrumentation, providing ...
Defining DNA-based operational taxonomic units for microbial-eukaryote ecology
DNA sequence information has been increasingly used in ecological research on microbial eukaryotes. Sequence-based approaches have included studies of the total diversity of selected ecosystems, the autecology of ...
Larvae from afar colonize deep-sea hydrothermal vents after a catastrophic eruption
The planktonic larval stage is a critical component of life history in marine benthic species because it confers the ability to disperse, potentially connecting remote populations and leading to colonization of new sites. ...
Sedation at sea of entangled North Atlantic right whales (Eubalaena glacialis) to enhance disentanglement
(Public Library of Science, 2010-03-09)
The objective of this study was to enhance removal of fishing gear from right whales (Eubalaena glacialis) at sea that evade disentanglement boat approaches. Titrated intra muscular injections to achieve sedation were ...
Seismic reflection images of a near-axis melt sill within the lower crust at the Juan de Fuca ridge
The oceanic crust extends over two thirds of the Earth’s solid surface and is generated along mid-ocean ridges from melts derived from the upwelling mantle. The upper and mid crust are constructed by dyking and seafloor ...
Deep-sea mining of seafloor massive sulfides
The potential emergence of an ocean mining industry to exploit seafloor massive sulfides could present opportunities for oceanographic science to facilitate seafloor mineral development in ways that lessen environmental harms.
Anatomy of an oil spill : long-term effects from the grounding of the barge Florida off West Falmouth, Massachusetts
(Yale University, 1980-05)
To determine carefully the effects on the marine and estuarine benthos of Number 2 fuel oil spilled by the barge FLORIDA off West Falmouth, Massachusetts, we sampled for many months along an onshore-offshore gradient of ...
The stability of arc lower crust : insights from the Talkeetna Arc section, south-central Alaska and the seismic structure of modern arcs
(American Geophysical Union, 2006-11-11)
One process for the formation of continental crust is the accretion of arc terranes at continental margins. A longstanding problem with this model is that although the composition of the continental crust is andesitic, ...
Acoustic intensity fluctuations induced by South China Sea internal tides and solitons
Between late April and May 23, 2001, a suite of acoustic and oceanographic sensors was deployed by a team of U.S., Taiwan, and Singapore scientists in the northeastern South China Sea to study the effects of ocean variability ...
