The effects of water content on diffuse reflectance spectrophotometry studies of deep-sea sediment cores
Sediment cores recovered during ODP drilling operations are commonly scanned using a Minolta CM-2002 spectrophotometer to obtain spectral data. Core processing procedures aboard the JOIDES Resolution require that these spectral data be measured on wet cores. However, the effects of changing water content on the spectra of marine sediments is unknown. We examined the effects of changing water co...
متن کاملMercury adaptation among bacteria from a deep-sea hydrothermal vent.
Since deep-sea hydrothermal vent fluids are enriched with toxic metals, it was hypothesized that (i) the biota in the vicinity of a vent is adapted to life in the presence of toxic metals and (ii) metal toxicity is modulated by the steep physical-chemical gradients that occur when anoxic, hot fluids are mixed with cold oxygenated seawater. We collected bacterial biomass at different distances f...
متن کاملEmergence of coherent wave groups in deep-water random sea.
Extreme surface waves in a deep-water long-crested sea are often interpreted as a manifestation in the real world of the so-called breathing solitons of the focusing nonlinear Schrödinger equation. While the spontaneous emergence of such coherent structures from nonlinear wave dynamics was demonstrated to take place in fiber-optics systems, the same point remains far more controversial in the h...
متن کاملPotential Health Benefits of Deep Sea Water: A Review
Deep sea water (DSW) commonly refers to a body of seawater that is pumped up from a depth of over 200 m. It is usually associated with the following characteristics: low temperature, high purity, and being rich with nutrients, namely, beneficial elements, which include magnesium, calcium, potassium, chromium, selenium, zinc, and vanadium. Less photosynthesis of plant planktons, consumption of n...
متن کاملThe Sodium and Potassium Content of Sea Water
EVER since the investigations of Forchhammer in the middle of last century it has been known that the composition of sea water throughout the mass of the oceans is relatively constant, and that, whatever be the degree of concentration or dilution, the ratios between the concentrations of the principal components vary, if at all, between narrow limits. Modern workers have not only confirmed this...
