The goal is to familiarize students with methods and instrumentation in marine research, as well as their capabilities and limitations. After successfully passing the exam, students will be able to plan and organize a simpler research field trip or a simpler experiment in the laboratory, and choose what is important to measure and at what dynamics in order to test a hypothesis or monitor a possible impact.
Lectures:
1. Introductory remarks.
2. Planning fieldwork, planning experiments in the laboratory.
3. Defining goals.
4. Collecting oceanographic data: measuring sea depth (one-, two- and three-dimensional display of results), measuring sea temperature and salinity, measuring the direction and speed of sea currents, recording sea level, measuring light and transparency of the sea, buoys with instruments for long-term measurements, remote sensors - aerial and satellite images.
5. Taking sea water samples, measuring chemical parameters (nutrients, organic matter, metabolic gases, trace elements).
6. Research institutes and ships in Croatia.
7. Underwater observation (in situ): scientific diving (range, dangers, physiological limitations of man), submarines (manned, remotely operated), underwater filming (cameras, cameras).
8. Biological sampling: plankton, nekton, benthos, sediment samples, preliminary sampling, necessity of quantitative sampling, sampling dynamics and its significance, sample labeling, recording of other data, influence of various factors on sampling (time of day, time of year).
9. Suitability of selected methods, range of measured values.
10. Processing of collected data.
