Prior to the mid-twentieth century, oceanographers largely conceptualized the abyssal benthic zone as an ecologically static repository, sustained exclusively by a slow, uniform rain of organic detritus originating from epipelagic surface waters. This oceanographic orthodoxy was challenged by the discovery of benthic storm events—episodes of intense, transient abyssal currents capable of scouring bottom sediments and resuspending organic material over thousands of square kilometers. Early measurements revealed that far from experiencing invariant stagnation, abyssal communities exhibit sudden metabolic spikes following these high-energy disturbances. Subsequent sediment-trap studies demonstrated that benthic storms expedite the vertical transport of surface-derived particulate organic carbon by generating localized turbulent mixing that captures fast-sinking aggregates. Consequently, researchers began to suspect that abyssal benthic fauna possess physiological adaptations tailored to episodic resource surpluses rather than continuous starvation. While early models treated the deep ocean bed as a homogenous sink operating near ecological equilibrium, contemporary findings suggest that benthic ecosystems are dynamically structured by unpredictable hydrodynamic flux, requiring a fundamental revision of global carbon-budget models.

Based on the passage, which of the following can be inferred regarding oceanographic understanding of the abyssal benthic zone prior to the mid-twentieth century? Consider each of the three choices separately and select all that apply.
