Overview

What is she best known for?

The fields of study she is best known for:

  • Ecology
  • Sedimentary rock
  • Groundwater

Her primary scientific interests are in Rare-earth element, Geochemistry, Groundwater, Carbonate and Aquifer. Her study on Groundwater is covered under Hydrology. Within one scientific family, Karen H. Johannesson focuses on topics pertaining to Inorganic chemistry under Carbonate, and may sometimes address concerns connected to Metal, Dissolved organic carbon, Sorption and Total organic carbon.

Her Aquifer research incorporates themes from Carbonate rock and Volcanic rock. The study incorporates disciplines such as Organic matter and Mineralogy in addition to Speciation. Karen H. Johannesson interconnects Environmental chemistry and Carbonate Ion in the investigation of issues within Mineralogy.

Her most cited work include:

  • Factor analytical approaches for evaluating groundwater trace element chemistry data (209 citations)
  • Speciation of rare earth elements in natural terrestrial waters: assessing the role of dissolved organic matter from the modeling approach (198 citations)
  • Rare earth elements (REE) and yttrium in stream waters, stream sediments, and Fe–Mn oxyhydroxides: Fractionation, speciation, and controls over REE + Y patterns in the surface environment (179 citations)

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

Her main research concerns Groundwater, Geochemistry, Aquifer, Environmental chemistry and Hydrology. Her Groundwater research includes themes of Seawater, Trace element, Spring and Surface water. Her Geochemistry research integrates issues from Sediment and Carbonate.

Many of her research projects under Aquifer are closely connected to Alkalinity with Alkalinity, tying the diverse disciplines of science together. Her work deals with themes such as Organic matter, Mineralogy and Arsenic, which intersect with Environmental chemistry. Her Submarine groundwater discharge, Groundwater discharge, Hydrology and Arsenic contamination of groundwater study in the realm of Hydrology connects with subjects such as Biogeosciences.

She most often published in these fields:

  • Groundwater (49.67%)
  • Geochemistry (42.48%)
  • Aquifer (35.29%)

What were the highlights of her more recent work (between 2016-2021)?

  • Environmental chemistry (39.87%)
  • Sediment (30.07%)
  • Geochemistry (42.48%)

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

Karen H. Johannesson spends much of her time researching Environmental chemistry, Sediment, Geochemistry, Groundwater and Estuary. The Environmental chemistry study combines topics in areas such as Organic matter, Tungsten and Arsenic. Her work in Sediment tackles topics such as Brackish water which are related to areas like Salt marsh.

Groundwater is a subfield of Hydrology that she investigates. Borrowing concepts from Rare-earth element, she weaves in ideas under Estuary. Her Aquifer research incorporates elements of Arsenate and Arsenite.

Between 2016 and 2021, her most popular works were:

  • Rare earth element behavior during groundwater–seawater mixing along the Kona Coast of Hawaii (41 citations)
  • Contrasting dissolved organic matter quality in groundwater in Holocene and Pleistocene aquifers and implications for influencing arsenic mobility (37 citations)
  • Biogeochemical Controls on the Release and Accumulation of Mn and As in Shallow Aquifers, West Bengal, India (23 citations)

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

  • Ecology
  • Sedimentary rock
  • Redox

Karen H. Johannesson mainly focuses on Groundwater, Biogeochemical cycle, Environmental chemistry, Estuary and Sediment. Her Groundwater study contributes to a more complete understanding of Hydrology. Her study focuses on the intersection of Environmental chemistry and fields such as Organic matter with connections in the field of Arsenic and Dissolved organic carbon.

Her studies in Dissolved organic carbon integrate themes in fields like Nitrate, Rhodochrosite and Mineralogy. Her work in Estuary addresses issues such as Salinity, which are connected to fields such as Oil shale, Particulates, Bank and Carbonate. Karen H. Johannesson combines subjects such as Geochemistry, Pore water pressure, Brackish water and Biogeochemistry with her study of Sediment.
