  • Hello,

    Thank you for making this data available to the public. I was wondering if the other inlets contain these same organisums specifically Portland Inlet, Nasoga Gulf, Little Channel, Alice Arm and in the Chatham Sound?

    Thank you for your time on this matter,

    Sarah Heinlein

    • Hi Sarah,

      Apologies for our slow response to your question! Our notification system was apparently down but it has now been fixed.

      I have seen data within Portland Inlet but I am not sure whether similar glass sponge reefs have been observed in the other areas you mention. Geogratis provides bathymetric data for sponge reef areas but only those within Hecate Strait and Queen Charlotte Sound. You might be able to find a bit more information in the references within DFO’s conservation strategy for corals and sponges: http://www.pac.dfo-mpo.gc.ca/oceans/protection/docs/cscs-pcce-eng.pdf. Otherwise, I would suggest contacting Natural Resources Canada or the Canadian Hydrographic Service as they are likely the best sources of information.

how to access the restricted data

This feature was created from 1 raw data layer. Each data layer has a custodian and different restrictions as to which types of data BCMCA may distribute on this website. The unrestricted feature and Marxan-ready data are available to download at the map & data tab. To gain access to the restricted data, please go through the following process:

  1. Determine whether you are interested in the feature data or Marxan-ready data. (See the Glossary for descriptions on these data types.)
  2. Using the info below, make a list of the custodians you will need to contact for permission to use the data. Please note that many of the features use similar data layers and require permission from the same custodians. Also note that BCMCA does not supply the contact information for the custodians, but they can be found through web searches. Then contact each of the custodians directly, indicating:
    • which features you are requesting permission to have data for
    • whether you are requesting the feature data or Marxan-ready data
  3. When all of the required permissions have been received for a feature or set of features, please forward the email confirmations to the BCMCA data custodian at info@bcmca.ca to obtain the data.

An index of all the data custodians for ALL features is available here.
