This is a working and communication space for the coastal ecosystem assessment project. Project coordinators: Jonny Stark, Ben Raymond

A copy of Jonny's presentation from the MEASO conference can be found here.

 


 

Discussion points arising from the MEASO Thursday lunchtime session

  • our definition of "coastal" is open to further discussion: will we consider only depth in defining our domain of interest, or also e.g. distance from the coastline? Note that other definitions of "coastal" or "nearshore" already exist (e.g. via AntOS)
  • AntOS is in the process of collating a database with coastal physical and biological data. There was an AntOS survey regarding important survey sites (https://www.scar.org/scar-news/antos-news/antos-survey/). A summary of this survey will be presented at the Davos conference
  • one of the early tasks of this project will be to collate and summarize the existing literature and data, e.g. intertidal, tourism (IAATO), plastics
  • something resembling the risk assessment table from Alex Rogers' Somerville workshop may be useful: a table that cross-tabulates processes and effects with knowledge and data, thereby summarizing the importance and state of knowledge/data of each
  • the spatial and temporal coverage of data will also be important, since the vast majority of coastal science has been conducted in spatially-limited areas or during limited temporal periods. Case studies could be conducted in particular areas where data coverage is suitable
  • keep intended use of data in mind as we go, and the scope of policy/other stakeholder outcomes and interests
  • terrestrial processes that affect the nearshore zone will be important here, but these terrestrial components themselves aren't of direct focus. There are parallel bodies of work that are already addressing those processes
  • similarly but more broadly, there are many other projects and initiatives that cover parts of this project's domain of interest. Coordinating this projects work with those other initiatives will be important
  • will our "coastal ecosystem" domain include areas under ice shelves or glacier tongues? Collapse of these features is likely to be of interest. Note that there was workshop on Antarctic Ecosystem Research Following Ice Shelf Collapse and Iceberg Calving Events held in late 2017 at Florida State University, organised by Jeroen Ingels and collaborators (see https://marinelab.fsu.edu/labs/ingels/outreach/polar-academy/). A review paper from this workshop is in preparation

 

Agenda of the MEASO Thursday lunchtime session

(Note that names of individuals who expressed interest in specific components of the work have been indicated below. This information is a bit thin at the moment, and will be updated as it evolves)

 

MEASO – Coastal ecosystems – vulnerability to climate change meta-analysis meeting

Facilitators: Jonny Stark and Ben Raymond

Aims

  • to get a first cut idea of what info exists,
  • identify what needs doing initially, and
  • who is volunteering to do it

 

Other considerations

Scope

Structure

Collaboration platform: Google docs, SOKI, others?

  • Email list
  • Reference list
  • Data list

 

We will run through the 20 or so general areas and get a quick summary of who/what for each.

  1. Coastal ecosystem features and definition
  2. Coastal/shallow water habitat distribution
  3. Processes causing or likely to cause change in coastal ecosystems:
  4. “Icescape” (Rob Massom)
    1. Sea ice
    2. Fast ice
    3. Polynas
    4. Bergs/glaciers
    5. Ice shelves and ice sheet margin (Jeroen Ingels)

 Sea ice and light

  1. Ice scour
  2. Freshening/melt
  3. Winds/waves and weather
  4. Sedimentation
  5. Ocean acidification
  6. Seawater temperature
  7. Blue carbon
  8. Invasive species
  9. Pollution (Catherine King)
  10. Species physiological tolerances
  11. New habitats
  12. Impacts on ecosystems: (Stacy Deppler, Alyce Hancock, James Black)  
    1. Changes in community composition, regime shift, tipping points.
    2. Changes to primary production
    3. Changes to food web dynamics, trophic links.
    4. Loss of diversity. Extinctions?
    5. Links to terrestrial processes (Aleks Terauds, Jasmine Lee)
    6. Links to terrestrial habitat use by marine species
    7. Data mapping and analysis (Anton Van de Putte, Huw Griffiths, Ben Raymond)
    8. policy/management
    9. Needs and future directions
      1. ROMS
      2. Bathymetry
      3. other
      4. Connections and implications, will change in coasts drive change elsewhere?

 

There will be a brief discussion of the synthesis component (i.e. tying all those pieces together). It is very likely that this will require new analysis work. Points of interest include:

  • Discussion of a general understanding of how the different stressors might interact with each other, so that we can work towards ideas on how that analysis will best be done
  • Possible outputs (GIS layers, possibly some kind of interactive widget thing, perhaps a summary for the environments portal (https://www.environments.aq/information-summaries).
  • Identify other stakeholders/end users that we might want to keep in touch with as work progresses
