The marine features atlas encompasses marine
habitats, marine mammals, seabirds, oceanography and ecosystem
components that are not included in the fish and shellfish atlases.
Most of the maps presented here are contributions from others
organizations including Gwaii Haanas National Park Reserve and Haida
Heritage Site and Living Oceans Society.
Our collective understanding of the marine
ecosystems around us is by no means complete. In fact, the data shown
in these maps represents only what we know – not the breadth
of information that we do not know. So consider these living documents
that will grow and mature in keeping with current research and
knowledge.
Living
Oceans Maps
Living Oceans Society has been actively involved
in mapping of marine features and marine ‘habitat’
modeling throughout the British Columbia coastline for several
years. The results of two marine habitat modeling
analyses by Jeff Ardron of Living Oceans Society are shown below.
Bottom
complexity is a unique measure, developed to show how
‘complex’ (ie. convoluted) the sea bottom
topography is relative to areas surrounding it. The Conservation
Utility map is a result of the MARXAN computer model. In very
simplistic terms, the model uses available physical and biological
datasets for generally fixed marine features – such as depth
and bottom type, kelp and eelgrass – for input, generating
areas of high to low potential conservation value based on parameters
set for the model run. Results of this model have particular utility in
broad-scale marine planning. For more information about MARXAN,

from the Living
Oceans Library.
