Elliot & McLusky 2002 🌎🔭🔬⚗ Flashcards
What does this paper consider?
What the definition / classification of estuaries has taught us
Why we need s classification system for estuaries
Why do we need to define estuaries
Difficulties and dilemmas of trying to define estuaries and its constituent parts
What do Elliot & McLusky 2002 present?
Generic framework for the definition, classification, monitoring, assessment, reporting and management of estuaries because the existing definitions will never be suitable for all needs - A DIFFERENT APPROACH IS NEEDED.
What approach do Elliot & McLusky (2002) propose?
‘Expert Judgement Checklist Approach’ - could provide guidance for those needing to define / delimit an estuary, whilst still acknowledging the variability of such systems.
What does the Expert Judgement Checklist Approach relate to?
European, temperate estuary but there are lessons for estuaries world wide.
Why is a checklist approach needed?
Because legislators need to understand the scientific approach that a wide ranging approach is needed as our environments are far too complex to be summarised be a few sentences
What is acknowledged about estuary definitions?
It is insufficient for scientists to reply on legal and socieconomic definitions drawn up by non scientists. Eg WFD - expert judgement is the last resort to define reference conditions - this paper argues it should be the first resort.
Give examples of the checklist approach?
Presence of erosion - deposition cycles?
Turbidity maximum zone?
Are the nutrients not limiting?
