15-06-2016 Morning Edit

- How is the N-cycle linked with the deep sea sediment? Does Global Change have a role in this?

- Figure Fishmarket Florida decreasing catch, biodiversity and body-size: explain, give causes and consequences.

- What are the important factors that affect estuary biota? List from most important to least important.

- Design a research programme to assess the environmental consequences of a energy atoll with a diameter of 3km, located 7km west of the coast of Zeebrugge. You have access to a research vessel (the simon stevin). Money and people are not an issue, but time is, you have to report after the first and second year.

- Words: Chlorophyll c; Re=2wrv; Cananoid copepod;sublittoral; Intermediate disturbance hypothesis

Edit

17-09-15 (Course given by Ilaria Coscia) - morning session

- Research question (ORAL part) : an energy plant was made in an estuary in front of the Belgian coast. You have to set up a research program which will investigate the impact of this in two years, without money limitations

- what is secondary production and how it can be evaluated

- diagram Irradiance/Photosynthetic rate (Slides of primary production) Explain the graph and define Ec, Ek, Pmax

- Euphotic, Carrying capacity, Beam trawl, Stramenopiles, DOM

17-09-15 (Course not give by Volckaert, but by Ilaria Coscia) - afternoon

Diagram of compensation depth and critical depth: explain

Picture of biological carbon pump: explain

Which factors can limit growth in the ocean?

Words: CTD, Trophic yield, Estuary, chemoautotrophy

Research question: marine reserve area is made in front of the Belgian coast. You have to set up a research program which will investigate the impact of this marine reserve area on the coast. (unlimited funding!)

Silica is commonly a limiting factor in the ocean. How is this possible? When and where does this happen?

Figure: Diurnal migration of plankton (chapter 7, fig 7.5): explain

Irigoien: What did they find + why was this study necessary? (+ why so many authors?)

Research question: You have to investigate the impact of a new canal in the western Scheldt. You have access to a research vessel (the simon stevin). Money and people are not an issue, but time is, you have to report after the first and second year.

words: POC, NPP, Pierre-Joseph Van Beneden, Picoplankton, Neritic zone


18-06-13 We had 4 questions (oral) and 5 definitions (written)

1. How is the N-cycle linked with the deep sea sediment?

2. Fig 2.8 (2.2.2. Photosynthetic pigments): Explain and what are the consequences for the ocean

3. Irigoien et al.: Why was this research so importent for marine science

4. Quantify the Porpoises population that seemingly performed a shift from the northern to the southern North Sea. You have acces to a 70m research vessel and a drone. Funds and people are no problem, but you only have 2 years

5. Assimilation, Bathypelagic, Beam trawl, Shear stress, Intermediate disturbance hypothesis


5 oral questions 10 points each (1 about papers), answer in a structured way, 300 words max (30lines) and 10 definitions, written-only, 2 points each.


19-06-12 VM

  1. How is the phosporus cycle linked with the deep sea sediment ?
  2. Interpret the following graphs : graphs of Chl a content in low/high light acclimated algae
  3. What is the connection between the Reynols number and larvae of starfish ?
  4. Design a research programme for two years (strict timing) to assess the environmental consequences of a gas spill of a well in the Central North Sea, you will have unlimited funding and people and two research vessels (70m and 25m) at your disposal.
  5. Irigoien et al. on copepod hatching determined that "diatoms" aren't toxic, why did they had to research this seemingly trivial question ?
  6. Definitions (explain in a marine context and in max. 50 words) :
Phycnocline, hypo-osmotic, polychaete, beam trawl, DON, North Atlantic Oscillation Index, PAC, Dinoflagellate, compensation depth, non-native species

19-06-12 NM

  1. What is the role of silica in phytoplankton? Is it a vitamin, a nutrient, something else?
  2. Evaluate this picture: fishcatch around the world (discuss why fish is caught a lot in some places and almost not in others)
    Fish landings
  3. Marine ecologists say that bacteria are important in marine ecosystems. Why?
  4. You are assigned to quantify the ecosystem after 50% less nutrient input (due to the installation of a new water purification plant) from the Wester Scheldt till 20km before the mouth. People and funds are no problem but time is. You only have 2 years and need to give in results after each year. You have acces to two research vessels (70m and 25m).
  5. Siegel D.A. et al (science 2002: The North Atlantic spring phytoplankton bloom and Sverdrup's critical depth hypothesis) modified Sverdrup's critical depth hypothesis. Was this modification necessary?
  6. Definitions (explain in a marine context and in max. 50 words) :
Continental shelf, MSY, stramenopiles, logarithmic bottom layer, DOM, hydrodynamic front, kelp, ecosystem resilience, macrobenthos, nansen bottle.
