“…Marine debris is an increasing problem in oceans worldwide and poses several environmental, economic and health issues (Gregory, 2009;Hayes et al, 2015). As a result, there is a rising concern about the negative effects that this form of pollution may have on sea life (Thompson et al, 2004;Moore, 2015).…”

“…using models). There is a wealth of practical guidance for selecting appropriate indicators and their unit of measure, including conceptual frameworks, such as the Driver‐Pressure‐State‐Impact‐Response framework (Mace & Baillie, ), and computational approaches, such as state‐and‐transition models (Rumpff, Duncan, Vesk, Keith, & Wintle, ) and qualitative loop models (Hayes et al., ).…”

Decision triggers show great potential for facilitating timely management action, promoting evidence‐based management and preventing undesirable changes to the status of species, ecosystems and threats. Integration of decision triggers into day‐to‐day management practice has been slow, constrained by insufficient resources and limited in‐house expertise. Arguably, the greatest impediment is the lack of an overarching process with robust and accessible methods for developing and implementing decision triggers in a manner that fits within an organization's established processes and skill sets. We identify the steps necessary for setting decision triggers and highlight how these steps align with commonly used conservation planning and management frameworks, for ease of adoption. We emphasize that decision triggers do not require a known ecological threshold, and can be applied to data‐rich and data‐poor contexts, with single or multiple management objectives. Synthesis and applications. This work highlights the necessary steps involved, and importantly, the suite of methods that can be used to set decision triggers, with the aim of supporting practitioners in the development of robust and defensible decision triggers.

“…In many cases, benefitting fully from satellite capabilities will require recurrent interaction among users and those responsible for mission planning and subsequent data processing. Such recurrent interaction will be particularly important for the ongoing efforts to develop essential variables for monitoring and assessing marine ecosystems, in part because biological and ecological characteristics interact in ways that are often complex, poorly understood and, especially relevant to our discussion, varying in importance seasonally and over time (Hayes et al 2015). To illustrate, high up on the list of candidate essential marine ecosystem variables is satellite-observed, color-variant chlorophyll concentration, indicative of phytoplankton density and primary production more generally.…”
