Sequence differences in the tRNA-proline (tRNApro) end of the mitochondrial control-region of three species of Pacific butterflyfishes accumulated 33– 43 times more rapidly than did changes within ...
Comparisons of genomic sequence between divergent species can provide insight into the action of natural selection across many distinct classes of proteins. Here, we examine the extent of positive se...
Nearly all target detection "radars" in existence operate at microwave frequencies because their wavelengths are small enough that compact antennas provide both good angular resolution and high sensit...
Measuring and interpreting the optical properties of ocean waters has been, and continues to be a challenging endeavor in oceanography. Just as the measurements of temperature~ salinity and density (T...
The last hundred years have seen a revolution in our understanding of ocean processes. I have selected a subset of seven topics. Technological developments generally led (rather than followed) new ide...
Immediately following World War II, the faculty and research staff at Scripps Institution of Oceanography, under the leadership of Director Roger Revelle, began to grow quickly to meet the new challen...
Quaternary continental shelves and coastal areas record the impact of relative sea-level changes as well as the influence of fluctuations in sediment supply. Relative sea-level change (i.e., its rate ...
Over the last 15 years marine scientists in Europe have come together to work on a range of scientific problems related to the geological, physical, chemical, and biological processes that control the...
The Labrador Sea is the coldest and freshest basin of the North Atlantic. Winter cooling in this sea produces Labrador Sea Water. This intermediate water plays an important role in the exchange of hea...
Numerous observational and modeling studies of ocean circulation surrounding Taiwan have reported occurrences of cold water and doming of isotherms (called the cold dome) that result in the formation ...
Publication of this special issue of Oceanography is one of the several ways that the Intergovernmental Oceanographic Commission is being recognized for 50 years of outstanding service to the communit...
Seamount systems that are geographically, hydrographically, topographically, and/or genetically "isolated" are likely to have developed highly endemic taxa and ecosystems. Although current estimates o...
The present study examines oxygen and phosphorus dynamics at a seasonally hypoxic site in the Arkona basin of the Baltic Sea. A coupled benthic–pelagic reactive-transport model is used to describe th...
We show rapid microevolution of one component of invertebrate innate immunity, phenoloxidase activity, in a natural population of the water fleaDaphnia magna.InDaphniahatched out of different depths o...
The evolution of damped basin-scale internal waves was investigated using a modal analysis for layer-stratified rotating lakes. A simple model for homogeneous oscillatory boundary layers was incorpora...
