We present the geomorphology of the Eastern Samoa Volcanic Province, covering 28,446 km², and depths ranging from ~50-4000 m. A new compilation of available multibeam data reveals 51 previously undocumented seamounts, and delineates major submarine rift zones, eruptive centers, and volcanic plateaus. Moving from a regional to local scale, and...
Xylem is nonuniform in its structure and function throughout the plant stem. Xylem structure varies from pith to bark, from root to apical meristem, from stem to branch, at nodes vs internodes, and at junctions of branches, stems or roots compared to the internodal regions nearby. At smaller scales, anatomy...
Our oceans surround us, and we depend upon them for food, transportation, and recreation. They affect us daily as they shape our climate and rattle our world with unexpected events. Current headlines indicate that they are in flux and perhaps in trouble. Coral reefs are dying due to rising ocean...
