Lagrangian floats as sea floor imaging platforms
There is a persistent need for high resolution photographic images of the sea floor and associated biota for marine habitat classification and fisheries stock assessment. This paper presents a novel low cost Lagrangian imaging platform that offers high quality images with reduced operational demands in comparison to existing methodologies such as diver surveys, drop cameras, ship towed systems ...
متن کاملSurprises from the sea floor
Unknown planet: Around 72% of the Earth’s surface is covered by oceans, and much of that surface is still unchartered territory for science. (Graphic: SuperStock.) More than seventy percent of the surface of our planet is covered by oceans. 88 percent of their area is deeper than 1,000 metres and thus difficult to access for research. There are only a handful of research submersibles that can d...
متن کاملExtending the sub-sea-floor biosphere.
Sub-sea-floor sediments may contain two-thirds of Earth's total prokaryotic biomass. However, this has its basis in data extrapolation from ~500-meter to 4-kilometer depths, whereas the deepest documented prokaryotes are from only 842 meters. Here, we provide evidence for low concentrations of living prokaryotic cells in the deepest (1626 meters below the sea floor), oldest (111 million years o...
متن کاملMR imaging of pelvic floor relaxation.
The wide variety of available surface coils, pulse sequences, and post-processing techniques make MR imaging a useful clinical and research tool for evaluation of pelvic floor relaxation. Cases of isolated cystocele do not require imaging; however, in cases in which multiple compartments of the pelvis are involved or the patient has failed prior surgery, MR imaging should be considered for preo...
متن کاملNew Tools for Decomposition of Sea Floor Pressure Data
In recent years more and more long-term broadband data sets are collected in geosciences. Therefore there is an urgent need of algorithms which semiautomatically analyse and decompose these data into separate periods which are associated with different processes. Often Fourier and Wavelet Transform is used to decompose the data into short and long period effects but these fail often because of ...
