Deep seabed mining:Frontiers in engineering geology and environment

Ocean mining activities have been ongoing for nearly 70 years,making great contributions to industrialization.Given the increasing demand for energy,along with the restructuring of the energy supply catalyzed by efforts to achieve a low-carbon economy,deep seabed mining will play an important role in addressing energy-and resource-related problems in the future.However,deep seabed mining remains in the exploratory stage,with many challenges presented by the high-pressure,low-temperature,and complex geologic and hydrodynamic environments in deep-sea mining areas,which are inaccessible to human activities.Thus,considerable efforts are required to ensure sustainable,economic,reliable,and safe deep seabed mining.This study reviews the latest advances in marine engineering geology and the environment related to deep-sea min-ing activities,presents a bibliometric analysis of the development of ocean mineral resources since the 1950s,summarizes the development,theory,and issues related to techniques for the three stages of ocean mining(i.e.,exploration,extraction,and closure),and discusses the engineering geology environment,geological disasters,in-situ monitoring techniques,envi-ronmental protection requirements,and environmental effects in detail.Finally,this paper gives some key conclusions and future perspectives to provide insights for subsequent studies and commercial mining operations.

Poultry gut health-microbiome functions,environmental impacts,microbiome engineering and advancements in characterization technologies

The gastrointestinal tract(GIT)health impacts animal productivity.The poultry microbiome has functions which range from protection against pathogens and nutrients production,to host immune system maturation.Fluctuations in the microbiome have also been linked to prevailing environmental conditions.Healthy poultry birds possess a natural resistance to infection.However,the exploration of environmental impacts and other relevant factors on poultry growth and health have been underplayed.Since good performance and growth rate are central to animal production,the host-microbiome relationship remains integral.Prior to the emergence of metagenomic techniques,conventional methods for poultry microbiome studies were used and were low-throughput and associated with insufficient genomic data and high cost of sequencing.Fortunately,the advent of high-throughput sequencing platforms have circumvented some of these shortfalls and paved the way for increased studies on the poultry gut microbiome diversity and functions.Here,we give an up-to-date review on the impact of varied environments on microbiome profile,as well as microbiome engineering and microbiome technology advancements.It is hoped that this paper will provide invaluable information that could guide and inspire further studies on the lingering pertinent questions about the poultry microbiome.
