Tutorial 2#

Open the notebook CTD transects and run all cells to generate some plots#

  • modify your data directory data_dir

Plot CTD transects for different variables#

Remember your MFP cruise plan and the bathymetry of the North West Shelf TODO: (links)

  • Explain why the data is available at different depths throughout the expedition

  • Are there temperatures that stand out? For example, temperatures below 0 degrees?

Play around setting ax.set_ylim() to zoom in on certain depth ranges

  • Describe the evolution of salinity along the transect

  • Explain why salinity changes close to land

Oxygen:

  • Describe the evolution of oxygen along the transect

  • Where is the lowest oxygen found and why do you think this is the case?

Nitrate:
Is there nearest to land there are very high nitrate values

  • Explain why this is the case

pH

  • Hypothesize why pH is lower in some spots

  • Is there an obvious correlation with temperature or other variables?

Phytoplankton (Chlorophyll)

  • Where are the highest concentrations of chlorophyll?

  • Is there an obvious correlation with temperature or other variables?

Discussion points#

  • Which variables are most affected by proximity to land?

  • How do you expect these variables to change with climate change?

Reflection#

  • Are there locations where you would have liked to take more measurements?

  • Why? and how would you modify the cruise plan?
