Map of carbon storage areas in Canada’s oceans.
These areas are delimited by depth boundaries that represent where each ‘habitat’ type may be found. Subsea permafrost is found at depths of 0–120 m, north of 60°N, and methane clathrates are found below 300 m.

Trajectory of Aboriginal Needs current status over time.
The Aboriginal Needs goal includes the extent of sea ice and the cost of participating in traditional hunting or fishing (i.e., gasoline price) relative to the cost of purchasing food.

Fig 3.
Original Ocean Health Index (OHI) and Canadian OHI (COHI) scores, for individual goals or subgoals (coloured petals) and overall (central number) for 2013.
In COHI–Equal, all goals have equal weighting; in COHI–BW-DCE, goals are weighted based on a latent-class discrete choice model coefficients. Numbers in italics show goal current status. Mariculture (MAR) and Fisheries (FIS) subgoals are part of the Food Provision goal; Aboriginal Needs (AN); Natural Products (NP); Carbon Storage (CS); Coastal Protection (CP); Tourism & Recreation (TR); Livelihoods (LIV) and Economies (ECO) subgoals are part of the Coastal Livelihoods goal; Iconic species (ICO) and Lasting Special Places (LSP) subgoals are part of Sense of Place; Clean Waters (CW); Habitat (HAB) and Species Protection (SPP) subgoals are part of the Biodiversity goal.
Fig 4.
Four weighting schemes for combining constituent goals or subgoals of the Canadian Ocean Health Index.
Weights are represented as the height of each band, and the overall Index score is indicated at the top of each weighting scheme. ‘Equal’: all goal weights = 1; ‘Likert’: weights are derived from Likert-scale survey questions; ‘BW-Rank’ and ‘BW-DCE’: weights are derived from the answers of best/worst survey questions. See Methods for details. Goal and subgoal codes are as in Fig 3.
Fig 5.
BW-DCE weighing across five regions for constituent goals or subgoals of the Canadian Ocean Health Index.
Weights are represented as the height of each band, as estimated by discrete choice model coefficients (see Methods for details), and the overall Index score is indicated at the top of each region. Similar letters above the overall Index indicate that the indices differed in less <5% of simulated cases. BC: British Columbia, Prairies: Alberta, Manitoba, and Saskatchewan, ON: Ontario, QC: Quebec, Atlantic: New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland. Goal and subgoal codes are as in Fig 3.
Fig 6.
BW-DCE weighing across six age groups for constituent goals or subgoals of the Canadian Ocean Health Index.
Weights are represented as the height of each band, as estimated by discrete choice model coefficients (see Methods for details), and the overall Index score is indicated at the top of each age group. Similar letters above the overall Index indicate that the indices differed in less <5% of simulated cases. Goal and subgoal codes are as in Fig 3.
Fig 7.
BW-DCE weighing across four political affiliations for constituent goals or subgoals of the Canadian Ocean Health Index.
Weights are represented as the height of each band, as estimated by discrete choice model coefficients (see Methods for details), and the overall Index score is indicated at the top of each political affiliation. Similar letters above the overall Index indicate that the indices differed in less <5% of simulated cases. NDP/Green: New Democratic Party & Green Party; LPC: Liberal Party of Canada; CPC: Conservative Party of Canada. Goal and subgoal codes are as in Fig 3.
Fig 8.
BW-DCE weighing of whether or not respondents are members of environmental non-governmental organisations for constituent goals or subgoals of the Canadian Ocean Health Index.
Weights are represented as the height of each band, as estimated by discrete choice model coefficients (see Methods for details), and the overall Index score is indicated at the top of each category. Similar letters above the overall Index indicate that the indices differed in less <5% of simulated cases. Goal and subgoal codes are as in Fig 3.
