Direct observations of tidal mixing and studies on ocean/climate variability synchronized with 18.6-year period nodal tidal cycle

强烈的潮汐引起的湍流混合到达千岛群岛或阿留申海峡周围的深海观测证实。这种强烈的垂直混合通过铁等营养物质的循环影响北太平洋亚北极的海洋生态系统。此外，观测和气候模式实验表明，源于18.6年周期的潮汐混合调制的海洋变化被日本东部海温和阿留申低压系统等海气相互作用放大，并调节着双年代际气候和海洋变化。

Intense tide-induced turbulent mixing that reached deep ocean around the Kuril or Aleutian Straits was observationally evidenced. This strong vertical mixing affects marine ecosystem in the subarctic North Pacific through circulations of nutrients such as iron. Furthermore, observations and climate model experiments revealed that oceanic variations originated from the 18.6-year period modulation of the tidal mixing in those regions are amplified by air-sea interactions such as SST east of Japan and the Aleutian Low Pressure system and regulate bi-decadal climate and ocean variations.
