Overview

What is he best known for?

The fields of study he is best known for:

  • Oceanography
  • Ecology
  • Paleontology

His primary scientific interests are in Oceanography, Foraminifera, North Atlantic Deep Water, Thermohaline circulation and Glacial period. His work on Oceanography is being expanded to include thematically relevant topics such as Paleontology. His Foraminifera research is multidisciplinary, relying on both Bottom water, δ18O and Radiocarbon dating.

His North Atlantic Deep Water research is multidisciplinary, incorporating elements of Younger Dryas, Climate change, Abrupt climate change and Atlantic multidecadal oscillation. His Glacial period study combines topics from a wide range of disciplines, such as Ice core, Holocene and Ice sheet. His Paleoclimatology study incorporates themes from Quaternary and Terrigenous sediment.

His most cited work include:

  • Collapse and rapid resumption of Atlantic meridional circulation linked to deglacial climate changes (1393 citations)
  • North Atlantic thermohaline circulation during the past 20,000 years linked to high-latitude surface temperature (717 citations)
  • Comparison of Atlantic and Pacific paleochemical records for the last 215,000 years : changes in deep ocean circulation and chemical inventories (589 citations)

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

His primary areas of investigation include Oceanography, Foraminifera, Table, Paleontology and Glacial period. All of his Oceanography and Holocene, Deglaciation, North Atlantic Deep Water, Deep sea and Last Glacial Maximum investigations are sub-components of the entire Oceanography study. He interconnects Younger Dryas and Radiocarbon dating in the investigation of issues within Deglaciation.

His studies in North Atlantic Deep Water integrate themes in fields like Atlantic multidecadal oscillation, Climate change and Gulf Stream. In his study, which falls under the umbrella issue of Foraminifera, Geomorphology is strongly linked to Geochemistry. His Glacial period research includes themes of Paleoclimatology and Ice sheet.

He most often published in these fields:

  • Oceanography (65.42%)
  • Foraminifera (29.15%)
  • Table (17.97%)

What were the highlights of his more recent work (between 2012-2021)?

  • Oceanography (65.42%)
  • Last Glacial Maximum (8.81%)
  • Holocene (14.92%)

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

His primary areas of study are Oceanography, Last Glacial Maximum, Holocene, Glacial period and Deglaciation. The concepts of his Oceanography study are interwoven with issues in Sediment, Climatology and Radiocarbon dating. His Last Glacial Maximum research is multidisciplinary, relying on both Abyssal zone, Water mass, Atlantic water and Deep sea.

His research in the fields of Stadial overlaps with other disciplines such as Vegetation. His Glacial period study deals with North Atlantic Deep Water intersecting with Abrupt climate change. His work deals with themes such as Younger Dryas, Physical geography, Quaternary science and Paleoclimatology, which intersect with Deglaciation.

Between 2012 and 2021, his most popular works were:

  • Formation of the Isthmus of Panama (327 citations)
  • North Atlantic ocean circulation and abrupt climate change during the last glaciation. (149 citations)
  • Anomalously weak Labrador Sea convection and Atlantic overturning during the past 150 years (142 citations)

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

  • Ecology
  • Oceanography
  • Paleontology

Lloyd D Keigwin mostly deals with Oceanography, Glacial period, Last Glacial Maximum, Deep sea and Deglaciation. His Oceanography and Foraminifera, Younger Dryas, Sea ice, Ocean current and Ice sheet investigations all form part of his Oceanography research activities. The various areas that Lloyd D Keigwin examines in his Glacial period study include North Atlantic Deep Water and Climate change.

His Last Glacial Maximum study also includes fields such as

  • Water mass together with δ13C,
  • Abyssal zone together with Holocene, Radiocarbon dating, Benthic zone and Seamount. His Deep sea research incorporates themes from Climatology and Interglacial. His Deglaciation research includes elements of Primary productivity, Stratification, Pacific ocean and Paleoclimatology.
