Seabed Observations at the New England Mud Patch: Reflection and Scattering Measurements and Direct Geoacoustic Information

Seabed Geoacoustic Structure at the Meso-Scale

The approach includes both theoretical and measurement components. One measurement approach exploits the very high geoacoustic information content in direct path measurements of seabed reflection and scattering. Another measurement approach, based on long-range reverberation, has much less information content but is nonetheless a powerful way to explore scales inherent in the seabed. Both kinds...

11: Seabed Geoacoustic Structure at the Meso-Scale

The observational approach is based on direct path measurements of seabed reflection and scattering. The key advantages of this approach are: 1) high resolution vertically, 0.1m and laterally: inner scale of ~10m and outer scale of 100 km; 2) it substantially reduces uncertainties from the space/timevarying oceanography and biology due to short path lengths; 3) it requires a low source level, 4...

the effects of multiple intelligences (focus on musical, visual, and linguistic) and direct instruction on learning grammar: a case on iranian efl students at elementary level

1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
