Deep-sea organisms research oriented by deep-sea technologies development
Science Bulletin, 2022Deep-sea environment, characterized by high pressures, extremely high/low temperatures, limited photosynthesis-generated organic matter, darkness, and high levels of corrosion, is home to flourishing special ecosystems in the world. Here, we illustrate how the deep-sea equipment offers insights into the study of life in the deep sea based on the work ...

Deep-sea sediments typically have sedimentation rates less than 30 m/10 years, and rates as low 0.1 m/10 years have been reported. The slow sedimentation rates and unusual sediment compositions reflect the low fluxes of aluminosilicates eroded from continents. The terrigenous material that does deposit is often windblown dust.

Deep-Sea Pleistocene Biostratigraphy
Science, 1966The first detailed paleontological analysis of a deep-sea pistoncore from the Caribbean Sea has been completed. The core, P6304-8, was raised from 3927 meters, east of Beata Ridge at 14°59′N, 69°20′W. Formerly, stratigraphic works in this area were based on studies of paleotemperature, measured by the oxygen isotope mass spectrometry method, or on ...

Deep sea navigation techniques
Marine Geophysical Researches, 1990Accurate navigation forms an essential part of all research at sea and the deep ocean imposes it’s own unique problems. This chapter discusses several of the techniques in current use on the research vessels of the Natural Environment Research Council (NERC), concentrating on those systems which provide global navigation facilities, as opposed to the ...

Deep sea, deep snow … deep space
2012We know that ultra-high-energy protons can travel on average only about 160 million light years before interacting with the cosmic microwave background and losing energy. Ultra-high-energy photons can’t even travel that far before being absorbed by the background.
