tetrapod.datum SURVEY // DL-0418 · HEADLAND MOLE SECT-09 (57°44'06"N 10°35'42"E) Coupled torsional strain, hydrophone comb-echo & diaphone acoustic survey across a 20-tonne Merrifield Dolos (DL-0418, 90° twisted octagonal H-flukes, 63% void porosity) wedged before an octagonal Jarlan roundhead caisson and twin cast-iron Type-F Diaphone foghorns (DIA-01). · T+01.10s / T+10.20s — Type-F Diaphone blasts open on a brassy D2–A2 fifth (73.4 / 110.0 Hz) across the headland, terminating in low-pressure piston grunts (03.70s, 12.80s) that droop to 46.2 Hz (F#1) as reservoir pressure vents. · T+02.45s / T+06.95s — Oblique wave-slam surge (+0.62 m OD) unloads the submerged fluke; during the subsequent trough drawdown, DL-0418 undergoes a -3.82° torsional roll and -18.4 mm vertical settlement away from its dashed yellow Epoch-0 datum contour, spiking shank-fillet waist strain (SG-02) to +412 uE and shifting the submerged HYD-09 void comb-reflection delay from 4.2 ms to 3.6 ms.
