Deep ocean blue holes possess steep physicochemical gradients, especially low dissolved oxygen concentration, which shape the extraordinary microbial communities. However, environmental responses of microorganisms with different lifestyles and knowledge culturable in are still unknown. Here, we investigated bacterial community structure world’s deepest hole - Yongle Blue Hole (YBH) South China ...

Ultraviolet (UV) radiation has a profound impact on marine life, but historically and even currently, most ocean color satellites cannot provide radiance measurements in the UV, thus UV penetration, global ocean. We develop system (termed as UVISRdl) this study, based deep learning, to estimate remote sensing reflectance (Rrs) at 360, 380, 400 nm (collectively termed near-blue bands, nbUV) from...
