Short summary
Environmental exposure histories can affect organismal sensitivity to climate change and ocean deoxygenation. The natural variability of environmental conditions for nearshore deep-sea habitats is poorly known due to technological challenges. We develop and test a novel, autonomous, hand-deployable lander outfitted with environmental sensors and a camera system and use it to characterize high-frequency oxygen, temperature, and pH variability at 100–400 m as well as seafloor community responses.
