Bioelectrical oscillations and scaling behaviour of sea mud

Abstract

This study uses a systematic approach to examine the bioelectric dynamics of marine sediments. We used an eight-channel recording system to measure bioelectric potentials. It had Pt/Ir electrodes and high-precision data acquisition (1 Hz sampling, 24-bit resolution). The setup was temperature-controlled (23±1 °C). It had optimized electrode placement to capture spatial variations. Our analysis revealed: (1) Channel-specific amplitude variations of 8.82±8.24 mV to 85.11±21.22 mV, indicating varied bioelectric activity; (2) A consistent periodic behaviour with mean intervals of ∼640 seconds across channels; (3) Power-law frequency scaling with exponents α∈[−1.49,−0.84], suggesting critical dynamics; (4) Strong spatial correlations (ρij=0.51−0.85) indicating coordinated network behaviour. The scaling exponents from detrended fluctuation analysis (αDFA=1.17−1.54) strongly support self-organized criticality. These findings suggest marine sediment is a natural info-processing network. It may have uses in unconventional computing and environmental sensing. The observed dynamics and coordination patterns show new, complex capacities. They could inspire bio-inspired computing architectures.
