Lehrinhalt

The lecture will be held by Prof. Dr. Luis Laglera from the University of the Balearic Islands (UIB, Palma de Mallorca) within a guest professorship at the Institute of Analytical Chemistry.

1.Oceanography. General description ocean properties and effects at a global scale. Reservoir of many substances. Important effect in heat transfer and weather. Huge economic importance as food source. Final destination of waste. Subjected to rapid change due to anthropogenic pressure (acidification, CO2 increase, pollution, deoxygenation).

NOTE: This content will be presented in the lecture series 771303 Environmental and Biotechnological analysis

2.Definition of water mass. Stratification and mixing.
3.Chemical oceanography. Complexity: highly concentrated heterogeneous matrix, very low concentrations.
4.Biological effect on ocean chemistry (uptake, defecation, exudation, light blockade)
5.Physical effects (currents, upwelling, solar radiation, temperature range, pressure, flocculation)
6.Chemical control of biological processes.
7.Analytical chemistry in oceanography. Need for more sensitive, selective and matrix independent techniques. Trends. Remote detection.
8.Chemical speciation. Organic and inorganic compounds interact changing their chemical an physical properties and their interaction with biota
9.Biogeochemical cycles. Element and compound cycling.


OCEAN RELEVANT PARAMETERS. Measurement and environmental relevance (hot topics).
10.Gas solubility. Oxygen. OMZ.
11.Gas solubility. The carbonate system. The ocean as CO2 sink and ocean acidification
12.pH. Ocean acidification.
13.Nutrients. Limitation. Eutrophication.
14.Dissolved Organic Matter composition. HPLC multidisciplinary applications.
15.Organic pollution. POP, emergent pollutants, microplastics.
16.Trace element cycling. Nutrients and pollutants: Hg, Pb

Inhaltliche Voraussetzungen (erwartete Kenntnisse)

Basics in general chemistry and analytical chemistry

Lehrziel

The interaction of chemistry and biology in aquatic environments is very different than that experienced in terrestrial ecosystems.

The study of the ocean chemistry, requires of the development of specific sampling strategies and analytical methods and techniques.

Concepts: water mass, ocean as a sink of pollutants, insitu vs exsitu vs remote vs lab analysis, biogeochemical cycles.

The students will be presented with the most challenging environmental problems affecting currently the ocean, predicted trends and the analytical tools available for their study.
