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...
Acoustic characterization of pelagic sediments using sub-bottom profiler data: Implications for the distribution of REY-rich mud in the Minamitorishima EEZ, 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...
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 ...

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...
Advances in Marine Ecosystem Dynamics from US GLOBEC: The Horizontal-Advection Bottom-up Forcing Paradigm
Global ocean ecosystem dynamics ecosystem climate Marine ecosystems
2015/7/16
A primary focus of the US Global Ocean Ecosystem Dynamics (GLOBEC) program was to identify the mechanisms of ecosystem response to large-scale climate forcing under the assumption that bottom-up forci...

Influence of bottom water anoxia on nitrogen isotopic ratios and amino acid contributions of recent sediments from small eutrophic Lonar Lake, central India
nitrogen isotopic ratios Influence
2014/4/2
Lonar Lake is a eutrophic, saline soda lake with permanently anoxic deep water. The high pH and
deoxygenation result in very elevated d15N of suspended particulate matter (SPM) and sediments due to
