In recent papers he was focusing on the following fields of study:

Nicholas J. P. Owens mostly deals with Phytoplankton, Oceanography, Ammonium, Nitrogen and Assimilation. His work on New production as part of general Phytoplankton research is frequently linked to Context, thereby connecting diverse disciplines of science. Many of his research projects under Oceanography are closely connected to Environmental resource management with Environmental resource management, tying the diverse disciplines of science together.

The study incorporates disciplines such as Photochemistry, Absorbance, Dissolved organic carbon and Colored dissolved organic matter in addition to Nitrogen. His Assimilation research incorporates themes from Algae, Diatom and Nitrogen assimilation. The study incorporates disciplines such as Drainage basin, Hydrology, Estuary, Turbidity and Saturation in addition to Salinity.

Between 1999 and 2020, his most popular works were:

  • Methane in the southern North Sea: Low-salinity inputs, estuarine removal, and atmospheric flux (130 citations)
  • Bacterial diversity in the bacterioneuston (sea surface microlayer): the bacterioneuston through the looking glass (85 citations)
  • The large capacity for dark nitrate‐assimilation in diatoms may overcome nitrate limitation of growth (78 citations)

In his most recent research, the most cited papers focused on:

  • Ecology
  • Oceanography
  • Ecosystem

His scientific interests lie mostly in Nitrate, Oceanography, Sea surface microlayer, Pseudoalteromonas and Microbiology. The various areas that he examines in his Nitrate study include Ammonium and Algae, Botany, Darkness. His Oceanography research integrates issues from Phytoplankton, Spring bloom and Algal bloom.

His Sea surface microlayer research is multidisciplinary, incorporating elements of Neuston, Library, 16S ribosomal RNA and Vibrio.
