Developing an ocean best practice: A case study of marine sampling practices from Australia

Introduction

An ocean best practice is a “methodology that has repeatedly produced superior results relative to other methodologies with the same objective; to be fully elevated to a best practice, a promising method will have been adopted and employed by multiple organizations” (Pearlman et al., 2019). Best practices can include manuals, guides, protocols and standard operating procedures, but they all share a common goal to improve the quality, consistency, and effectiveness of data acquisition and accessibility. They include some or all aspects of the ocean observation value chain, from planning through to derived products. Using ocean best practices has many benefits including more collaborative opportunities, efficient use of time, improved systems operability, data comparability and interoperability, greater trust in data, streamlined regulatory approvals, and higher funding success (e.g. (Pensieri et al., 2016; Rivest et al., 2016; Walker et al., 2021).

The systematic development and use of ocean best practices is supported by the Ocean Best Practices System (OBPS) (Pearlman et al., 2019) (www.oceanbestpractices.org). The centerpiece of this international program is the OBPS Repository, a searchable and secure interface that allows the submission and retrieval of all ocean practices, including those fully elevated to best practices (Hörstmann et al., 2021). Other facets of the OBPS include a journal research theme, a UN Ocean Decade program (Ocean Practices), training and capacity development, and various task teams focused on discrete projects or disciplines (e.g. -omics).

Since 2012, there has been a surge in the number of marine science publications that use the term ‘best practice’ in their title or topic (Figure 1), yet the term is not often defined, nor the process behind the practice development described. Is it necessary to clearly articulate how ocean best practices are developed to ensure consistency and meaning when one refers to a ‘best practice.’

Importantly a ‘best practice’ is more than a documented practice that an individual or institution uses and considers good. This article aims to describe a rigorous process to develop an ocean best practice using examples from a case study from Australia. Although we focus on an Australian case study, there are of course other practices that have been developed using a similar approach (e.g. QARTOD Quality Assurance of Real Time Oceanographic Data in Bushnell et al. (2019), Monitoring and Regulation of Marine Aquaculture in Read et al. (2001). The case study used here is the Field Manuals for Marine Sampling to Monitor Australian Waters, a suite of nine standard operating procedures (referred to henceforth as Australian SOPs) released in 2018, which have since become national best practices for marine survey design, multibeam echosounders, autonomous underwater vehicles (AUVs), benthic and pelagic baited remote underwater video systems (BRUVs), towed imagery, sleds and trawls, grabs and box corers, and remotely operated vehicles (ROVs). This project is described in more detail in Przeslawski et al. (2019b) and at https://marine-sampling-field-manual.github.io. More than 136 individuals from 53 agencies contributed to the Australian SOPs, and the process underpinning their development highlights the broader challenges and benefits of developing best practices.

As presented below, the process to develop a best practice includes three phases 1) scope and recruit, 2) develop and release, 3) revise and ratify; this article is similarly structured. Each phase includes several steps and actions that are supported by the Ocean Best Practices System (Figure 2, www.oceanbestpractices.org). The Australian case study differs from many other practices, which only use the second phase (develop and release). This paper will emphasize the value of the other phases to ensure a practice is truly a ‘best practice’.

Phase 1: Scope and recruit

The first step to develop a best practice is to confirm the need, including identifying potential users. This may involve an audit of existing practices, workshops or questionnaires which may reveal similar practices or multiple practices that could be converged. No one wants to go through this whole process only to find that it has already been done by someone else or will only have a handful of users! It may also be useful to identify the drivers for a proposed best practice which may include the need for consistent reporting or for metrics to be linked integrated monitoring (Essential Ocean Variables in Muller-Karger et al. (2018). For the Australian SOPs, a questionnaire was released to the Australian marine science community to identify user needs and gauge interest in contributing to a working group. Similar methods were also reviewed by searching scientific databases. This was done before the full development of the Intergovernmental Oceanographic Commission’s OBPS Repository (www.oceanbestpractices.org), which now provides a useful a tool for such a search (Samuel et al., 2021). Results from the review or questionnaire were then compiled in a scoping report to identify potential knowledge gaps and to document this first step (Przeslawski et al., 2019a).

After the need for a best practice has been confirmed, a working group and leader(s) should be formed. The working group leader should have expertise on the topic and have the time and ability to organize people and make decisions about potentially contentious issues. Before assembling the working group, the leader must set the scope of the best practice document to manage expectations. A best practice cannot address everything; it may need to be limited to a particular instrument, environment, or metric. The logistics and format of the working group will vary among regions and communities, and there is no ideal number of participants. The Australian SOPs had varying working group sizes, ranging from eight members (sled and trawl SOP) to 48 members (multibeam SOP). For this step, the overriding principle is inclusivity, and all major potential contributors and institutions should be invited to participate. Invitations can be extended individually or through newsletters, workshops or other public fora. In many ways, this is the most important step to set a future best practice up for success. The more perspectives able to be included in a working group, the stronger the best practice will be, and the more ownership and uptake will eventuate.

Phase 2: Develop and release

This second phase is the one that will be most familiar to many researchers, as it is indispensable in the development of any practice, let alone a best practice. The working group develops content by first applying the learnings from the first phase to decide if and how to integrate related methods into their practice. The working group will then undertake several iterations of consultations and draft methods (referred to as a strawman in Figure 2) until they have a final draft. There may be disagreements during this iterative process. In these cases, the majority or working group lead should decide which method to use. More formal decision-making processes may also be explored (e.g. Loizidou et al., 2013). Importantly, these choices should be clearly documented and justified in the final draft. For the Australian SOPs, where there were disagreements about including a particular step, the step was often included but clearly marked as recommended, not essential. At other times, the working groups developed more innovative ways to integrate seemingly disparate recommendations. For example, in the grab and box corer SOP, working group members advocated for different sieve sizes (1000, 500, 300 µm). Ultimately, the SOP puts forward the 500 µm sieve size as the consistent national standard, but states that if ‘individual survey objectives require a finer mesh size … or comparison with datasets from larger mesh size … [the user can] layer the sieves and process samples separately so that the recommended standard of 500 µm is still followed and data are comparable.”

After the working group has agreed on a final version, the next step is a formal review process. This can either be done through submission to a journal via their peer-review process (e.g. Langlois et al., 2020; Mantovani et al., 2020; Parks et al., 2022) or managed through the working group via an external review process. It is insufficient for working group members alone to review the practice. If the practice is likely to be used by a large number of users, we also recommend the working group solicit input more broadly through a consultation period or online questionnaire that invites feedback from potential users. The working group will then respond to these reviews and revise the method, documenting decisions and responses to feedback in an adjudication record, with major points addressed in the revised version of the method. The Australian SOPs were each externally reviewed by at least two experts in the field, with some of these reviewers providing such valuable input that they were included as authors in the subsequent version.

After revision, the practice is ready to be released, if it has not already been done so through a scientific journal’s peer-review process. The process of appropriately documenting a best practice is described in Hörstmann et al. (2021). The way a practice is released depends on resourcing and user preferences and can include traditional formats such as institutional reports or scientific journal articles, as well as more modern formats such as apps, webpages or videos. The first version of the Australian SOPs was released as static pdfs, but the second version also included an online GitHub portal (https://introduction-field-manual.github.io). This digital delivery system was chosen due to the following benefits:

• The practices are easily accessible in online or pdf formats, increasing the flexibility of user experiences and needs.

• The online system readily reflects minor corrections by harvesting through the source document maintained on an online file repository, in this case Google Docs.

• Updates and version control are easier to manage through permissions on GitHub and Google Docs.

• Analytics are easily generated to track downloads, which can then be incorporated into impact assessments.

• The online system has more flexibility to embed imagery and other media and to maintain links to external resources.

If a working group does not have the capability to host a practice, they can upload the practice directly to the Ocean Best Practices Repository, during which it will also be assigned a DOI. Regardless of the way in which a practice is released, the meta-data should be submitted to the Ocean Best Practices Repository to make a new practice findable to the international community. Importantly, after a practice is released and listed in the OBPS Repository, the working group should notify key stakeholders and promote to target audiences using newsletters, social media, or conference and workshop presentations.

Phase 3: Revise and ratify

Most ocean practices are considered complete after they are released, but a final phase (revise and ratify) is required to elevate them to a ‘best practice’. Once a practice is released, the working group should invite feedback from the community to understand how and why the practice is being used and to identify any necessary revisions. When considering the definition of a best practice, this step is particularly important because it shows that the practice is ‘adopted and employed by multiple organizations’ (Pearlman et al., 2019). When the Australian SOPs were first released, contact details and a simple web-form were shared for users to offer suggestions or report errors; these were compiled over the following year. During this same period, we also assessed uptake through analytics generated by the OBPS Repository and Google Analytics. These and other measures were compiled in a report on impact and outcomes of the Australian SOPs (Przeslawski et al., 2021).

Based on feedback and uptake, it may be appropriate to revise the practice. If this is the case, the working group is reformed, and the second phase starts again (Figure 2). Revisions can be minor to reflect recent studies, technological advances, or new digital infrastructure; or they can be more substantial in which case another review period is warranted. An example of the latter is the Australian multibeam SOP that was first released in 2018 at the same time as a very similar practice from AusSeabed, an emerging seabed mapping initiative. During Phase 3 of the Australian SOPs, we noted the similarity between the two practices, and a partnership between the two programs yielded a converged second version that was released in 2020 (Picard et al., 2020). Although often desirable, convergence or extensive revision of best practices could potentially result in changes in the way in which data are collected such that data are no longer consistently comparable over time. This must be considered during best practices revisions, and if major method changes are proposed, a window of overlap between the old and new methods could facilitate comparisons between them to map interoperability.

Once a practice has been released, the working group should seek community endorsement from broader discipline representatives or end users so that the practice can become a true best practice. The Global Ocean Observing System (GOOS) offers an international endorsement process for best practices (Hermes, 2020) which details several criteria including a rigorous community review process (see Phase 2). At the time of writing, this is the only established endorsement process for an international ocean best practice. Other endorsements may come from institutions and permitting agencies who may recommend or require your method be used in ocean activity permissions. The endorsement process for the Australian SOPs varies among the numerous best practices. For example, the BRUV SOP (Langlois et al., 2020) received GOOS endorsement, the multibeam SOP is used by many entities collaborating with the AusSeabed program (e.g. Geoscience Australia, CSIRO, Australian Hydrographic Office, Australian State governments and universities), and all the SOPs are used by the Australian Federal Government (Parks Australia – Marine Parks Branch) as recommendations in permitting and requirements in contracts.

The final step is to maintain and update what is now a best practice. This is particularly relevant for those practices incorporating emerging technologies, developing data infrastructure, or tentative workflows. For example, the -omics methods often used in biomolecular ocean observing and research are rapidly evolving and may require more frequent updates (Saito et al., 2019; Samuel et al., 2021). Periodic reviews of the practice will help identify outdated information that can be corrected with a new version. For long-term maintenance, particularly of lengthy best practices or compendiums of best practices such as the Australian SOPs, an oversight committee will be useful.

Challenges

The process to develop a best practice takes time and effort, and it has numerous challenges. Some of these relate to content, such as ensuring the method is fit-for-purpose and within scope, but arguably the more significant challenges relate to people and institutional resistance. Because of the highly collaborative nature of this process, there may be many people and institutions involved, thus posing issues related to following deadlines with numerous time-poor colleagues, reaching consensus when two groups disagree on key aspects, and balancing flexibility to help ensure uptake with prescriptiveness to help ensure data comparability.

Although the process described in this paper may be challenging and time-consuming, it optimizes the chance to develop a true best practice that is:

• Fit-for-purpose with clearly defined scope;

• Representative and inclusive of potential users;

• Accurate and effective, reflecting emerging technologies and programs; and

• Supported and adopted by users.

Conclusions

This paper illustrates the three major phases and accompanying steps to develop an ocean best practice, providing associated examples from a case study from Australia. Many practices are only developed with a single phase (develop and release), and we accentuate the importance of the other two phases (scope and recruit, revise and ratify) which are required for a true best practice. These phases also have other benefits, including higher uptake of a practice stemming from a sense of shared ownership (from scope and recruit phase) and currency and accuracy (from revise and ratify phase). Importantly, the approach documented here is highly collaborative and iterative, with the final step linking to earlier steps and potentially yielding subsequent versions (Figure 2). This will ensure a long lifespan of a best practice.

An additional benefit of the Australian SOP approach was the development of multiple related ocean practices at the same time. These SOPs are often used concurrently to characterize the geomorphology and ecology of a marine area. The impact of the SOPs and their value to users would have been diminished if they had progressed separately in an uncoordinated manner over different timeframes.

At a national scale, the Australian SOPs have been used to ensure consistency in data acquisition and data quality, such that data are interoperable at national scales. This allows scientists, managers and policymakers in Australia to 1) meet state and federal goals for integrated monitoring (e.g. National Marine Science Plan in Hedge et al. (2022), New South Wales Marine Integrated Monitoring Program in Aither (2022)), 2) report on internationally agreed metrics Miloslavich et al. (2018) and Muller-Karger et al. (2018) at local to national scales, and 3) adopt a best practice-based approach to monitoring the vast network of Australian Marine Parks that will ideally spread into many other applications that are comparatively unguided and unregulated regarding standards for data collection and management (e.g. naval mapping, offshore energy exploration and development). Industry can then adopt such best practices to improve environmental assessments and regulation (e.g. offshore wind in North Sea in Abramic et al. (2022)).

At a global scale with the United Nations Decade of Ocean Science for Sustainable Development, it is imperative that we continue developing, using, and maintaining the currency of existing best practices to ensure that the science we undertake locally or regionally can complement that undertaken elsewhere (Pearlman et al., 2021). This will contribute to improving our understanding of our global ocean and the changes it faces, which in turn will assist other ocean stakeholders in policy and management to make science-driven decisions.
