    Novel tools and methods for monitoring marine environments can improve efficiency but must not compromise long-term data records. Quantitative comparisons between new and existing methods are therefore required to assess their compatibility for monitoring. Monitoring of shallow water coral reefs is typically conducted using diver-based collection of benthic images along transects. Diverless systems for obtaining underwater images (e.g. towed-cameras, remotely operated vehicles, autonomous underwater vehicles) are increasingly used for mapping coral reefs. Of these imaging platforms, towed-cameras offer a practical, low cost and efficient method for surveys but their utility for repeated measures in monitoring studies has not been tested. We quantitatively compare a towed-camera approach to repeated surveys of shallow water coral reef benthic assemblages on fixed transects, relative to benchmark data from diver photo-transects. Differences in the percent cover detected by the two methods was partly explained by differences in the morphology of benthic groups. The reef habitat and physical descriptors of the site-slope, depth and structural complexity-also influenced the comparability of data, with differences between the tow-camera and the diver data increasing with structural complexity and slope. Differences between the methods decreased when a greater number of images were collected per tow-camera transect. We attribute lower image quality (variable perspective, exposure and focal distance) and lower spatial accuracy and precision of the towed-camera transects as the key reasons for differences in the data from the two methods and suggest changes to the sampling design to improve the application of tow-cameras to monitoring.

    Adapting research methodology during COVID-19: Lessons for transformative service research
    (Emerald Publishing Limited, 8/02/2021) Dodds S; Hess AC
    Purpose Coronavirus disease 2019 (COVID-19) has created a challenging, yet opportunistic, environment in which to conduct transformative service research (TSR) and assess research methodology. The purpose of this paper is to evaluate and gain important new insights of a group interviewing method with vulnerable people and their support group, adapted and transferred online during COVID-19. Design/methodology/approach This research examines the experiences of 35 participants (nine family groups composed of parents and young people), involved in a research project that explores a sensitive topic, youth alcohol consumption and family communication, that was moved online during lockdown. Researcher reflections on running group interviews face-to-face prior to COVID- 19 and online during lockdown are included in the data. Findings Thematic analysis of participant interviews and researcher reflections reveals four key benefits and three limitations of online group interviews with vulnerable people and their support group. The benefits include being comfortable, non-intrusive and safe; engaging and convenient; online communication ease and easy set-up. The limitations relate to lack of non-verbal communication, poor set-up, and privacy and access issues. Practical implications The global environment is uncertain and being able to implement effective qualitative research online is essential for TSR and service research in the future. This paper provides a step by step procedure for an innovative online group interviewing technique that can be used by TSR and qualitative service researchers. Originality/value Conducting research during a pandemic has provided unprecedented insights into qualitative research approaches and methodology. This paper contributes to literature on service and TSR methodology by providing a framework for researchers to investigate vulnerable groups online in an effective, safe and non-intrusive way. The framework also has the potential to be applied to other service contexts.
