What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Oceanography
  • Bacteria

His main research concerns Oceanography, Ecology, Ocean gyre, Ecosystem and Photic zone. He combines subjects such as Phytoplankton, Particulates, Carbon cycle and Biogeochemical cycle with his study of Oceanography. His Ecology research integrates issues from Nitrogen cycle and Metagenomics.

His Ocean gyre study incorporates themes from Deep sea and Biogeochemistry. In his study, Cyanobacteria is inextricably linked to Nitrogen fixation, which falls within the broad field of Ecosystem. His Photic zone research also works with subjects such as

  • Nitrate that intertwine with fields like Nitrogen,
  • New production which intersects with area such as Trichodesmium and Bloom.

His most cited work include:

  • Nitrogen cycles: past, present, and future (3413 citations)
  • The Sorcerer II Global Ocean Sampling Expedition: Northwest Atlantic through Eastern Tropical Pacific (1647 citations)
  • VERTEX: carbon cycling in the northeast Pacific (1497 citations)

What are the main themes of his work throughout his whole career to date?

David M. Karl mostly deals with Oceanography, Ocean gyre, Ecology, Environmental chemistry and Photic zone. His Oceanography study combines topics from a wide range of disciplines, such as Phytoplankton, Carbon cycle and Biogeochemical cycle. His Ocean gyre research is multidisciplinary, relying on both Nitrogen fixation, Diel vertical migration, Mixed layer and Prochlorococcus.

His Ecology research is multidisciplinary, incorporating elements of Metagenomics and Microbial population biology. He works mostly in the field of Environmental chemistry, limiting it down to topics relating to Phosphorus and, in certain cases, Nutrient, as a part of the same area of interest. His study in Photic zone is interdisciplinary in nature, drawing from both Nitrate, Particulates, Atmospheric sciences and New production.

He most often published in these fields:

  • Oceanography (47.64%)
  • Ocean gyre (24.41%)
  • Ecology (21.65%)

What were the highlights of his more recent work (between 2013-2021)?

  • Oceanography (47.64%)
  • Ocean gyre (24.41%)
  • Ecology (21.65%)

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

His scientific interests lie mostly in Oceanography, Ocean gyre, Ecology, Environmental chemistry and Subtropics. David M. Karl interconnects Phytoplankton, Particulates and Biogeochemical cycle in the investigation of issues within Oceanography. His research in Ocean gyre intersects with topics in Photic zone, Atmospheric sciences, Water column, Mixed layer and Diel vertical migration.

The Ecology study combines topics in areas such as Metagenomics, Microbial ecology and Microbial population biology. His Environmental chemistry study combines topics from a wide range of disciplines, such as Seawater, Carbon cycle, Phosphate and Methane. David M. Karl has included themes like Carbon sequestration, Climate change and Pelagic zone in his Ecosystem study.

Between 2013 and 2021, his most popular works were:

  • Scientists' Warning to Humanity: Microorganisms and Climate Change (263 citations)
  • Microbially Mediated Transformations of Phosphorus in the Sea: New Views of an Old Cycle (155 citations)
  • Diversity and Activity of Communities Inhabiting Plastic Debris in the North Pacific Gyre. (125 citations)
