Marine environmental geology
This is a suggestion for a Degree Project for Bachelor's and Master's levels at the Department of Marine Sciences. Degree projects at the Department of Marine Sciences are done independently and must be written and assessed individually.
Subject: Marine Chemistry
Level: Bachelor and Master
Supervisors: Kjell Nordberg or Lennart Bornmalm
Project description
Human impact on the marine environment is often reflected as oxygen deficiency in the sea with laminated and polluted sediments, as well as severe impact on marine fauna and flora (marine micropaleontology or eelgrass beds).
Here too, accumulation bottoms with continuous deposition of sediment, pollutants and microfossils constitute a useful environmental archive and a valuable tool for tracking the occurrence and spread of pollution and environmental changes over time. Heavy metals, environmental toxins, sediment structures, and microfossils are preserved in the sediments and can thus be used both temporally and spatially.
The marine environmental geology, with studies of historical oxygen deficiency and pollution, often has very strong advantages as we can use stratigraphic technology to work with older sediments where regular environmental surveys have not been carried out before.
Marine environmental geology is also closely linked to physical oceanography to elucidate dispersal mechanisms in the marine environment.
