Researchers at MIT have developed a technique for precisely controlling the arrangement and placement of nanoparticles on a material, like the silicon used for computer chips, in a way that does not d...
Antarctic Bottom Waters Freshening at Unexpected Rate
Antarctic Bottom Waters Freshening Unexpected Rate
2017/2/16
In the cold depths along the sea floor, Antarctic Bottom Waters are part of a global circulatory system, supplying oxygen-, carbon- and nutrient-rich waters to the world’s oceans. Over the last decade...
OPTIMAL IMAGE STITCHING FOR CONCRETE BRIDGE BOTTOM SURFACES AIDED BY 3D STRUCTURE LINES
Image Stitching 3D Structure Line Concrete Bridge Inspection
2016/7/27
Crack detection for bridge bottom surfaces via remote sensing techniques is undergoing a revolution in the last few years. For such applications, a large amount of images, acquired with high-resolutio...
Acoustic characterization of pelagic sediments using sub-bottom profiler data: Implications for the distribution of REY-rich mud in the Minamitorishima EEZ, western Pacific
REY-rich mud Minamitorishima EEZ sub-bottom profiler sediment classification western Pacific
2017/4/10
Sub-bottom profiling was conducted in the Japanese Exclusive Economic Zone (EEZ) around Minamitorishima Island,
western Pacific Ocean, to investigate the features and distribution of mud rich in rare...
A COMPUTATIONAL METHOD TO EMULATE BOTTOM-UP ATTENTION TO REMOTE SENSING IMAGES
Image interpretation Modelling Image understanding Texture Analysis Process modelling
2015/12/23
In this paper, we propose a computational model which is capable of emulating the expert’s bottom-up attention to remote sensing images. The bottom-up visual attention is a relatively primary step in ...
Quasi-parabolic reflecting bottom surfaces of the Drygalski Antarctic floating ice tongue
radio echo sounding radio glaciology glacier ice tongues
2015/9/28
Very high frequency deep radio sounding systems for ice thickness measurements are practically the only useful apparatuses for large scale radar flight surveys in polar regions. The morphology of the ...
Morphology of bottom surfaces of glacier ice tongues in the East Antarctic region
radio echo sounding radio glaciology glacier ice tongues
2015/9/28
During three Antarctic summer campaigns (1995/97/99) Radio Echo Sounding (RES) system data from some glacier ice tongues in the East Antarctic regions between Victoria Land and George V Land were coll...
A NEW TECHNIQUE BASED ON MINI-UAS FOR ESTIMATING WATER AND BOTTOM RADIANCE CONTRIBUTIONS IN OPTICALLY SHALLOW WATERS
UAS Ocean color Littoral waters Bottom reflectance Radiance Visible spectrum Saint Lawrence Estuary
2015/9/10
The mapping of nearshore bathymetry based on spaceborne radiometers is commonly used for QC ocean colour products in littoral waters. However, the accuracy of these estimates is relatively poor with r...
On the String Translations Produced by Multi Bottom–Up Tree Transducers
String Translations Produced Multi Bottom–Up Tree Transducers
2015/9/10
Tree transducers are defined as relations between trees, but in syntax-based machine translation, we are ultimately concerned with the relations between the strings at the yields of the input and outp...

2015/9/7
We report on the installation of a long-term buried ocean-floor broadband seismic station
(MOBB) in Monterey Bay, California (USA), 40km off-shore, at a water depth of 1000 m.
The station was instal...
From bottom landers to observatory networks
landers multidisciplinary long term observatories global change
2015/9/7
For a long time, deep-sea investigation relied on autonomous bottom landers. Landers can vary in size from 200 kg
weight to more than 2 t for the heaviest scientific landers and are used during explo...
Analysis of ADCP data above a bottom observatory
ADCP sensitivity current lines inclination observatory’ s wake
2015/9/7
A 300-kHz ADCP was set on GEOSTAR, a six-m3 deep-sea observatory. It was operated with cells of 80 cm during a three-week test experiment at 42-m water depth in
the northern Adriatic sub-basin. Altho...
