On April 22, 2026, the College of Marine Science and Engineering hosted the second session of the “Deep Blue Wisdom Forum” academic salon. The event was chaired by Associate Dean Yang Yang, who briefly reviewed the first academic salon and introduced the guest speakers for this session. The salon featured presentations by Professor Zhang Dong, Dr. Yang Jianghua, and Dr. Yu Pengpeng, each sharing insights from their respective research fields.
Professor Zhang Dong delivered a presentation titled “Remote Sensing of Coastal Zone Resources and Environment.” He systematically introduced his team’s recent research progress utilizing multi-source remote sensing technologies in areas such as coastal topography and geomorphology, wetland ecology, resource utilization, and maritime target identification. He showcased a series of research achievements, including integrated remote sensing reconstruction of underwater topography from intertidal zones to shallow seas and deep oceans, refined classification of coastal salt marsh wetlands, remote sensing assessment of island natural vulnerability, suitability evaluation of offshore wind energy resource development, and remote sensing estimation of offshore wind turbine scale, installed capacity, and carbon emission reduction. This research provides feasible strategies for the development and utilization of coastal zone resources and ecological environmental protection supported by remote sensing technology.
Dr. Yang Jianghua provided a systematic report on “Precision Biomonitoring Using Environmental DNA and Ecological Health Diagnosis.” Set against the backdrop of global biodiversity conservation, his presentation focused on the principles, advantages, and current technical bottlenecks of environmental DNA (eDNA) biodiversity monitoring. He specifically highlighted the enrichment of trace environmental DNA, the construction of native species DNA barcode databases, and continuous eDNA monitoring. These techniques enable non-invasive, highly sensitive detection of biodiversity, invasive alien species, and pathogens. This technology overcomes the limitations of traditional surveys and provides scientific, quantitative, and intelligent diagnostic support for water quality early warning, ecological restoration, and biosafety management.
Dr. Yu Pengpeng gave a systematic presentation on “Full-Ocean-Depth Piezoelectric Drive Technology.” He introduced the working mechanisms and performance characteristics of piezoelectric drives in extreme deep-sea environments, focusing on structural design, working principles, mechanical modeling, and interface morphology. He showcased the development of related prototypes and their performance under simulated deep-sea environmental testing. Additionally, he engaged in in-depth discussions with attending faculty members on directions such as cross-sea domain inspection robots, long-term service life, and engineering applications.
