“…This resulted in the first margin wide quantification of natural gas escaping the seafloor. Zhang et al (2019) used video footage of fluids escaping the Grotto vent at Endeavor ridge to study short-period variations in vertical fluxes of hydrothermal plumes. Quantitative analysis of digital video images of plumes using the particle image velocimetry method allowed the comparison of vents from midocean ridges around the globe.…”

Over fifteen years ago, Ocean Networks Canada (ONC) began with the world’s first large-scale, interactive, real-time portal into the ocean, bringing continuous, real-time data to the surface for applications in scientific research, societal benefits, and supporting Canada’s ocean industry. This marked the dawn of the Internet-connected ocean, enabling a more fulsome understanding of the ocean through ocean intelligence. These open data have improved our ability to monitor and understand our changing ocean offshore all three coasts of Canada, thanks to diversity of sensor systems to monitor earthquakes and tsunamis, deep sea biodiversity, whales, hydrothermal vents, neutrinos, ocean noise, ocean acidification, forensics experiments, and the impact of climate change, including sea ice thinning in the Arctic. This pioneering approach began in the late 1990s, when scientists began developing a new way of doing ocean science that was no longer limited by weather and ship-time. They imagined a permanent presence in the ocean of sensors to allow a continuous flow of ocean data via the Internet. This big science began to take shape early this century, when a partnership between United States and Canadian institutions was established. ONC evolved out of this international collaboration with seed funding from the Canada Foundation for Innovation, while in the United States, the Ocean Observatories Initiative (OOI) was funded. ONC works closely with OOI on that span the countries’ west coast border. Recently similar observing initiatives in Europe have begun, led by EMSO, which now has a close collaboration with ONC as an Associate Member.

“…图像区域互相关算法在实验流体力学中应用广泛 , 是粒子图像测速技术(Particle Image Velocimetry, PIV) [27,28] 和粒子图像追踪测速技术(Particle Tracking Velocimetry, PTV) [29] 的核心算法. 区域互相关算法的基本原理是计算前后两张图像中判读窗口的相似性, 以最大相似点的位移作为判读窗口的位移.…”

“…在该机制下, 羽流实验结果以及羽流积分模型理论均发现在近喷口区域 , 羽流截面流量随羽流上升近似线性增加 [35,36,37] . 经公式 [40] , 该畸变可以通过测量相机拍摄平面和热液羽流成像平面的夹角进行坐标转换矫正, 在本研究中, 热液羽流图像并未出现明显的透视现象, 因此由相机倾斜而导致的计算误差较小; (4)热液羽流与海水间的折射率差异造成光线偏移, 模糊羽流边缘; (5)图像互相关算法可能会对流速造成一定程度的低估 [28] .…”

“…(2) 海底冷泉与海底热液虽然属于不同的海底流体活动, 但二者在喷出海底后都往往会形成与周围海水存在性质差异的羽状流, 在同一个海洋系统中, 二者具有千丝万缕的联系 [1] . 前人已经利用PIV方法对热液喷口的流场进行了计算 [58,59] . Crone等人 (3) 基于PIV方法估算的海底冷泉气泡的流速, 与实验室测量和前人野外测量的速度具有很好的一致性 [21,60] .…”
