Feeding behavior of the ctenophore Thalassocalyce inconstans : revision of anatomy of the order Thalassocalycida
Behavioral observations using a remotely operated vehicle (ROV) in the Gulf of California in March, 2003, provided insights into the vertical distribution, feeding and anatomy of the rare and delicate ctenophore Thalassocalyce ...
Upgrades to StellaBase facilitate medical and genetic studies on the starlet sea anemone, Nematostella vectensis
(Oxford University Press, 2007-11-03)
The starlet sea anemone, Nematostella vectensis, is a basal metazoan organism that has recently emerged as an important model system in developmental biology and evolutionary genomics. StellaBase, the Nematostella Genomics ...
Actin polymerization controls the activation of multidrug efflux at fertilization by translocation and fine-scale positioning of ABCB1 on microvilli
(American Society for Cell Biology, 2012-08-01)
Fertilization changes the structure and function of the cell surface. In sea urchins, these changes include polymerization of cortical actin and a coincident, switch-like increase in the activity of the multidrug efflux ...
Paleoreconstruction of organic carbon inputs to an oxbow lake in the Mississippi River watershed : effects of dam construction and land use change on regional inputs
(John Wiley & Sons, 2015-10-10)
We use a dated sediment core from Lake Whittington (USA) in the lower Mississippi River to reconstruct linkages in the carbon cycling and fluvial sediment dynamics over the past 80 years. Organic carbon (OC) sources were ...
Expendable oceanographic mooring (XMOOR)
(Woods Hole Oceanographic Institution, 1997-04)
An expendable, self-deploying mooring (XMOOR) for shallow water applications has been developed to address Navy requirements for environmental monitoring. The project has been conducted jointly between the Woods Hole ...
Evidence for significant photochemical production of carbon monoxide by particles in coastal and oligotrophic marine waters
(American Geophysical Union, 2009-12-09)
Carbon monoxide (CO) photoproduction from particulate and chromophoric dissolved organic matter (CDOM) was determined in seawater from open-ocean and coastal areas. In confirmatory tests, poisoned or non-poisoned filtered ...
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.
Deglacial diatom productivity and surface ocean properties over the Bermuda Rise, northeast Sargasso Sea
(American Geophysical Union, 2009-12-12)
Diatom assemblages document surface hydrographic changes over the Bermuda Rise. Between 19.2 and 14.5 ka, subtropical diatom species and Chaetoceros resting spores dominate the flora, as in North Atlantic productive regions ...
Submeter bathymetric mapping of volcanic and hydrothermal features on the East Pacific Rise crest at 9°50′N
(American Geophysical Union, 2007-01-19)
Recent advances in underwater vehicle navigation and sonar technology now permit detailed mapping of complex seafloor bathymetry found at mid-ocean ridge crests. Imagenex 881 (675 kHz) scanning sonar data collected during ...
Geochemical cycling of silver in marine sediments along an offshore transect
Although there have been many surface water and water column silver (Ag) analyses in the ocean, the absence of high resolution pore water and solid phase Ag profiles has hampered our understanding of its oceanic geochemical ...
