Robust detection of marine life with label-free image feature learning and probability calibration
Machine Learning: Science and Technology, 2023 Advances in in situ marine life imaging have significantly increased the size and quality of available datasets, but automatic image analysis has not kept pace.

Quantifying the Ocean's Biological Pump and Its Carbon Cycle Impacts on Global Scales.
Annual Review of Marine Science, 2022 The biological pump transports organic matter, created by phytoplankton productivity in the well-lit surface ocean, to the ocean's dark interior, where it is consumed by animals and heterotrophic microbes and remineralized back to inorganic forms.

Ion pumps as biological targets for decavanadate [PDF]
Dalton Transactions, 2013 The putative applications of poly-, oligo- and mono-oxometalates in biochemistry, biology, pharmacology and medicine are rapidly attracting interest. In particular, these compounds may act as potent ion pump inhibitors and have the potential to play a role in the treatment of e.g. ulcers, cancer and ischemic heart disease.

Influence of atmospheric dust deposition on sinking particle flux in the northwest Pacific
Frontiers in Marine Science, 2023 We examined the flux and composition of sinking particles collected at a water depth of 800 m in the northwest Pacific from November 2017 to August 2018 to assess the impact of dust deposition on organic carbon export.

Epipelagic nitrous oxide production offsets carbon sequestration by the biological pump
Nature Geoscience, 2022 Substantial nitrous oxide production in the epipelagic zone of the subtropical ocean partially offsets carbon sequestration by the marine biological pump, according to observations from the South China Sea and subtropical northwest Pacific.
