Ophiuroid fauna of cobalt-rich crust seamounts in the Northwest Pacific Ocean
Wanying Chen, Jieying Na, Chengcheng Shen, Ruiyan Zhang, Bo Lu, Hong Cheng, Chunsheng Wang, Dongsheng Zhang
2021, 40(12): 55-78. doi: 10.1007/s13131-021-1887-y
Abstract:
Seamounts are vulnerable ecosystems in the deep sea and can be heavily impacted by human activities, such as bottom fishing and deep-sea mining. The species composition and distribution patterns of benthic fauna is key information for the designation...
Morphological description and population structure of an ophiuroid species from cobalt-rich crust seamounts in the Northwest Pacific: Implications for marine protection under deep-sea mining
Jieying Na, Wanying Chen, Dongsheng Zhang, Ruiyan Zhang, Bo Lu, Chengcheng Shen, Yadong Zhou, Chunsheng Wang
2021, 40(12): 79-89. doi: 10.1007/s13131-020-1666-1
Abstract:
Many seamounts are covered with cobalt-rich ferromanganese crusts, and are increasingly attracting interest for the potential extraction of valuable mineral resources from deep seabed environments. However, the impacts of potential mining activities ...
Ceuthonoe nezhai gen. et sp. n. (Polynoidae: Polynoinae) commensal with sponges from Weijia Guyot, western Pacific
