Questions

Which themes appear in both sources?

What new information have surveys added beyond what was already written in the literature?

How do themes vary between fishing vs. shipping contexts?

How do themes vary with positionality of the respondent (surveys only)?

Result 1: Bridges and barriers according to review and survey

Sunburst figure

Visualizes each of the themes (Data, Ecological, Social, and Implementation) identified in the literature and surveys. Also visualizes the sub-themes within each theme bin. Literature themes are on top while surveys are on the bottom. Cooler colors indicate bridges while warmer ones represent barriers. The small text/poor resolution should be resolved when the figure is viewed as a pdf!

Table

May include in the supplemental, but could be redundant to the sunburst diagram.

Result 2: Codes by review and survey

Result 2.1: Frequencies according to review and survey

Code appearance counts across all bridge OR barrier codes. The values represent counts of themes or sub-themes.

{fig-align=“center” width=“10in”, height = “12in”}

{fig-align=“center” width=“10in”, height = “12in”}

Result 2.2: Heat maps of theme co-occurence

This heatmap represents number of times two codes co-occurered together in the same article, or “theme co-occurence”. Bridges are placed on rows and barriers are separated by columns. Literature codes are on the top and survey codes are on the bottom.

{fig-align=“center” width=“10in”, height = “12in”}

{fig-align=“center” width=“10in”, height = “12in”}

Result 3: Variations by industry

3.1: Management and conservation problems DOM has been used to address

3.2: Fishing vs. shipping

{fig-align=“center” width=“5in”, height = “8in”}

{fig-align=“center” width=“5in”, height = “8in”}

Result 4: Variations by position (survey only)

{fig-align=“center” width=“8in”, height = “6in”}
