The Promise of Satellite Oceanography [PDF]
The goal of the Oceanic Processes Program at NASA is to evaluate the utility of spaceborne techniques for observing the oceans, and to apply these techniques toward advancing our understanding of fundamental oceanic behavior. This paper describes some of the oceanographical problems amenable to solution using satellite observations, such as the use of ...

ABSTRACT Openwork mountain block deposits (blockfields, blockstreams) have received much research interest globally given their visual appeal as prominent cold‐region landforms. However, studies have shown that these landforms in both glaciated and non‐glaciated environments are probably of considerable age (pre‐Quaternary), yet the environmental ...

Numerical solutions of a boundary value problem on the sphere using radial basis functions [PDF]
Boundary value problems on the unit sphere arise naturally in geophysics and oceanography when scientists model a physical quantity on large scales. Robust numerical methods play an important role in solving these problems. In this article, we construct numerical solutions to a boundary value problem defined on a spherical sub-domain (with a ...

Modeling hydrography and marine sedimentation in the Cariaco Basin since the Last Glacial Maximum [PDF]
The Cariaco Basin has shallow connections with the Caribbean Sea, and these are further reduced at times of lower sea level, such as at the Last Glacial Maximum (LGM).

[Comment on “The Oceanography Report”] Composition of the Oceanography Report
In looking over the subject matter of The Oceanography Report (TOR), beginning with the September 1, 1981, edition of Eos, I am struck by the predominance of physical oceanography lead articles. In fact, out of 63 articles, 23 are “pure” physical oceanography, 25 are multidisciplinary, general, or news and announcement articles, and the remainder are ...

ABSTRACT Megafauna became extinct during the late Quaternary, with climate changes and human activities the two main proposed extinction drivers. Palaeoloxodon naumanni (Naumann's elephant) and Mammuthus primigenius roamed the Japanese archipelago during the Pleistocene.

ABSTRACT In Ireland, the Nahanagan Stadial (NS) was characterised by cirque glacier, plateau icefield and mountain ice cap expansion and is named after the cirque glacier type‐site of Lough Nahanagan in the Wicklow Mountains. This period is broadly equivalent to the Younger Dryas Stadial and Greenland Stadial‐1 (GS‐1: ~12.9–11.7 ka).

On the wave turbulence theory for stratified flows in the ocean [PDF]
After the pioneering work of Garrett and Munk, the statistics of oceanic internal gravity waves has become a central subject of research in oceanography. The time evolution of the spectral energy of internal waves in the ocean can be described by a near-resonance wave turbulence equation, of quantum Boltzmann type.

ABSTRACT This paper presents evidence of glacier surging in the British landform record. We use new high‐resolution multibeam‐echosounder bathymetry data to map the submarine geomorphology of a former tidewater glacier that drained the Skye Icefield, NW Scotland, during the Younger Dryas Stadial (Greenland Stadial 1) ca. 12.9–11.7 ka.
