The Geometric, Crystallographic, and Hydrodynamic Blueprint of Braarudosphaera bigelowii: A Structural Principle for Dodecahedral Biomineralization

Synthesis of the structural, crystallographic, and hydrodynamic properties of the regular pentagonal dodecahedral exotheca of Braarudosphaera bigelowii. Includes Dynamic Shape Factor correction to Stokes' Law, golden-ratio volume derivation, and original modeling of suture obliquity (explicitly noted as derived rather than directly measured). Supports the conclusion that the organism's high density requires energetic coastal mixing. Builds on Larsen (2018).

Abstract

Synthesis of the structural, crystallographic, and hydrodynamic properties of the regular pentagonal dodecahedral exotheca of Braarudosphaera bigelowii. Includes Dynamic Shape Factor correction to Stokes' Law, golden-ratio volume derivation, and original modeling of suture obliquity (explicitly noted as derived rather than directly measured). Supports the conclusion that the organism's high density requires energetic coastal mixing. Builds on Larsen (2018).
