These large-scale studies estimated impacts on benthos (particularly removal rates per trawl pass), monitored subsequent recovery rates, measured natural dynamics of tagged megabenthos, mapped the regional distribution of seabed habitats and benthic species, and integrated these results in a dynamic modelling framework together with spatio-temporal fishery effort data and simulated management. Typical impact rates were between 5 and 25% per trawl, recovery times ranged from several years to several decades, and most sessile megabenthos were naturally distributed in areas where little or no trawling occurred and so had low exposure to trawling. The model simulated trawl impact and recovery on the mapped species distributions, and estimated the regional scale cumulative changes ...

Even in the last century, biological knowledge of the oceans remained more limited than that of physical ocean processes such as storms, tsunamis from undersea earthquakes and teleconnections, like El Niño. Yet, human exploitation of the oceans is accelerating, reaching greater depths (Figure 1) and having greater impacts on marine life. Many uses interact, as when ports displace fishing, chemical industries contaminate marine life, and greenhouse gases in the atmosphere acidify and warm the oceans. Sustainable, science-based ocean policies that mitigate human impacts urgently need enhanced knowledge of marine life.

Without integration, different groups manage different activities inconsistently, there are conflicts from overlapping or competing activities, and there is no ability to consider the cumulative impacts of multiple activities. Further, and increasingly important, some form of integration of management will be required to deal effectively with climate change. However to date there has not been an agreed approach for Integrated Management (IM). In 2017 and 2018, a team of researchers associated with the Centre for Marine Socioecology (CSIRO and UTas) and partners (SARDI and DFO), collaborated to develop a framework for implementation and a ‘lens’ for evaluation of Integrated Management (IM). The research team then convened two workshops to test the framework with a broader group of subject matter experts, and to apply the lens to Australian IM case studies. The case studies included Gladston...

However, few scienti f ic investigations of the subject have been made, perhaps because shell-gathering is usually done by women whereas anthropological studies often focus on hunting by men (Meehan, 1982).

Attended by 75 mostly early-and mid-career participants from Australia, New Zealand, Japan, and the United States, the workshop featured nine keynote presentations. Working groups identified important themes and challenges that are fundamental to understanding the Earth system. This research relies upon ocean-going research platforms to recover geological, geobiological, and microbiological information preserved in sediment and rock beneath the seafloor and to monitor subseafloor environments through the global ocean. The workshop program was built around five scientific themes: Biosphere Frontiers, Earth Dynamics, Core to Crust, Global Climate, Natural Hazards, and Ocean Health through Time. Workshop sessions focused on these themes and developed 19 associated scientific challenges. Underpinning these are legacy samples and data, technology, engineering, education, public outreach, big data, and societal impact. Although all challenges are important, the asterisks that follow denote those of particular relevance and interest to ANZIC. Ocean Health through Time comprises the ocean's response to natural perturbations in biogeochemical cycles*; the lateral and vertical influence of human disturbance on the ocean floor; and the drivers and proxies of evolution, extinction, and recovery of life*. Global Climate entails coupling between the climate system and the carbon cycle; the drivers, rates, and magnitudes of sea level change in a dynamic world*; the extremes, variations, drivers, and impacts of Earth's hydrologic cycle*; and cryosphere dynamics*. Biosphere Frontiers addresses the habitable limits for life*; the composition, complexity, diversity, and mobility of subseafloor communities*; the sensitivity of ecosystems to environmental changes; and how the signatures of life are preserved through time and space*. Earth Dynamics: Core to Crust encompasses the controls on the lifecycle of ocean basins and continents*; how the core and mantle interact with Earth's surface*; the rates, magnitudes, and pathways of physico-chemical transfer among the geosphere, hydrosphere, and biosphere*; and the composition, structure, and dynamics of Earth's upper mantle. Natural Hazards involves the mechanisms and periodicities of destructive earthquakes*; the impacts of submarine and coastal volcanism; the consequences of submarine slope failures on coastal communities and critical infrastructure*; and the magnitudes, frequencies, and impacts of natural disasters*. The ANZIC Ocean Planet Workshop will contribute to formulating the next science framework for scientific ocean drilling which in turn will guide the focused planning of specific drilling, logging, and monitoring projects.

In parallel with public health systems, a system to assess ocean health should evaluate the occurrence and severity of a set of syndromes of concern through a series of indicators composed from a parsimonious set of ecosystem essential ocean variables delivered by a coherent and robust observing system. The development of such approach for the global assessment of ocean health will help inform policies acting upon the drivers causing ocean syndromes and help ensure a healthy ocean for all.

A total of 906.4 km2 of seagrass habitat, fringing 671.1 km of coastline was identified, mapped and sampled. Eleven seagrass species (approx. 20% of all known species) were recorded. In all, 74% of the seagrass communities occur along open coastlines and are characterized by depth-zoned species distributions (intertidally and subtidally), variable shoot-surface areas and variable above-ground biomass values. Each zone was dominated bfone or two of the following species: Syringodium isoetifolium, Cymodocea serrulata, Halodule uninervis, Halophila ovalis and Halophila spinulosa. Of the remaining seagrass, 10% occurred on reef flats in mixed-species communities, !3% in a regionally restricted monospecific community of Halodule uninervis, and 4% in communities dominated by Enhalus acoroides.
