1939 Benioff & Gutenberg in Bull. Amer. Meteorol. Soc. 20 424/1 The waves..exhibit no relation to microseisms nor to the barometric conditions in this region. No hypothesis as to their origin has yet been suggested. We designate them microbaroms.

1953 Jrnl. Acoustical Soc. Amer. 25 796/1 Microbaroms apparently originate in ocean storms associated with low pressure areas.
