Field experiment: Measuring salinity#
Objectives#
Measure the salinity in the Elbe estuary
Make (and partially test) a hypothesis about sources of salinity variability
As one group, follow the exercise sheet for ideas about how to set up your experiment.
Tip
Divide tasks within the group for efficiency, but ensure everyone understands the whole process.
Suggestion#
Recommended location: since for WiSe2324 we‘ve been to work there.
Install necessary software or use lab computer. If using a lab computer, you must include this in your list of necessary equipment provided at 15:00 on the course day before the field excursion.
Tip
We can provide advice. If in doubt, ask before trying something.
Some ideas to get you started#
Find the salinity from the North Sea from literature or past Seepraktikums; find the salinity in the Elbe in Hamburg.
Identify a location for measurements. Use e.g. local maps or Google maps to check for water access. Ideally there will be a dock from which you can lower the instrument.
Find and note the expected tides for your chosen location and time of day.
You will likely need to make repeat measurements over at least 6 hours; decide the frequency of measurement and depth (if applicable).
Ensure you outline all required materials in time (including the required instruments and auxiliary equipment), needed ropes, floats, life vests, etc..
Plan the figures you intend to create from the data. When designing your experiment, consider what these figures will look like, and how you‘ll use the data to evaluate variability.
Warning
Human safety first. Equipment safety second.
