Chapter 4 Conduct: The OHI Toolbox
OHI assessments are highly collaborative, and include information and perspectives from different disciplines and stakeholders. For OHI assessments to be most efficient and transparent, we emphasize reproducibility and collaborative open data science tools. You will use the OHI Toolbox to calculate OHI scores for your assessment area, which leverages open data science tools: R, RStudio, git, and GitHub. Below are resources for your team to learn, which are good to begin as early as possible.

4.1 Overview of the OHI+ workflow
This overview reviews the core OHI features for the Framework and the Toolbox to help guide you as you tailor your assessment. It also describes recommended collaborative software (Google Drive) and required open source software (R, RStudio, GitHub) that you will use in your assessment.
4.2 What is the Toolbox?
These slides introduce the software and philosophy behind the OHI Toolbox. It emphasizes how OHI teams should establish collaborative practices that leverage open source software to make assessments more organized and transparent.
4.3 Intro to open data science
These videos follow the OHI training book Introduction to open data science. It is a hands-on introduction to a collaborative workflow with R, RStudio, Git, and GitHub, as described in Our path to better science in less time using open data science tools (Lowndes et al. 2017). This is recommended for analysts and collaborators working with data for OHI+ assessments.
4.4 Calculations: basic workflow
This video walks through Chapter 8 of the OHI Toolbox-training. It was recorded as a live-demo in 2018 to introduce OHI+ Kenya and OHI+ Tanzania teams to the Toolbox Workflow. Screensharing from RStudio and GitHub, it repeats the basic Toolbox workflow several times, using demo data, updated data, and updated models.
4.5 Calculations: advanced workflow
This Chapter of the Toolbox Training describes more advanced operations using the Toolbox. Additional information is included in Chapter 9: Pressures and Resilience and in the OHI Manual starting with Modifying goal models.
4.6 Uncertainty & gapfilling
These slides introduce uncertainty in the Ocean Health Index and how to approach gapfilling missing data in a responsible way. These slides accompany a publication Mapping Uncertainty Due to Missing Data in the Global Ocean Health Index (Frazier, Longo & Halpern 2016).
4.7 Further learning
- The OHI Manual is a good reference document as well.
- A bit of history: this is how the whole ohi-science.org website started; this was originally a PDF created from a Word Doc that we would email to interested groups and became a living resource whose current version is always available online.
